Technology of correct knitting of reinforcement under a stitch foundation. Reinforcement of a string foundation How to connect a string foundation, old and new

Correctly, a lot of what the durability of the architectural design means. The value of the reliable structure, in its own way, depends on the parameters of the reinforcement. One of the most important stages is knitting the reinforcement under. This frame can be built independently without compromising after thorough knowledge of technologies, tools, and materials. If the further implementation of the project will be entrusted to a development team, such information will help monitor the correctness of the actions of the Vikonavians.

Features of the stitch foundation

This type of foundation often stagnates, let us step on the peculiarities and advantages:

• Such a foundation follows the contours of the walls; therefore, there are fewer other materials in the leveled ones than in their monolithic counterparts.
• In fact, the simplest, most straightforward option is that it equally distributes the importance. When constructing small and other light structures, it is permissible to construct them without reinforcement.
• If necessary, install a laminated base with a frame in the middle. On weak soils you can get stronger.
• Production of such spores is possible using relatively inexpensive materials.

Such engineering solutions make it possible to provide reliable support at high levels, and in other insufficient supports. screw until it reaches the level of solid ground, and below the level of freezing. Solid reinforced concrete elements reinforce the power frame of the booth. At the pouring stage, they can be fitted with shutter parts.

Important! In any case, there is a need for a front extension of the design, the basis that carries. Accurate calculations will help optimize the expenditure of material and labor resources. If you know that there is not enough knowledge, seek help from professional fakivts. Additional technical data and the general part of professional documentation.

It is believed that metal fittings should be used against metal fittings, requiring greater respect for lower specialness.

Building structures use reinforced steel reinforcement manufactured according to the national standard 5781-82. For the production of such metal products, hot rolling technology is used. Precisely regulated: dimensions, height and placement of protrusions, steel grades. In order to increase resistance to corrosion, various types of alloying should be applied. Using additional laboratory techniques, the value and other technical parameters are verified.

For private living, fittings of class A 400 (A-III) with a diameter of 10 mm to 16 mm are suitable. In the most advanced areas, rods from 16 mm to 22 mm can be stiffened. As in the name, there is a letter “C” - so the components can be squeezed together from the frozen joints. The truth “K” is about additives that reduce anti-corrosion properties. Jumpers and other additional elements of the frame do not have great importance. They can be made from thin haircuts with a diameter of 6-10 mm (classes A 240 (A-I)) to A 300 (A-II).

It is necessary to understand that the reduction of parameters and additional possibilities will increase the quality of the product. However, increased resistance to oxidative processes is not required. After being caught in the deep concrete, there will be a vologger every day and the next morning. Apparently, the sympathetic minds of corrosion developments are switched off.

The authenticity of viruses before their development also requires consideration in the report. Such work operations are entrusted to highly qualified facists in order to avoid such inconveniences:

• When there is a high flow of electric arc, a high temperature can significantly reduce the value of the metal.
• A defect in the seam may cause the joint to fail at the stage of pouring the mortar.
• Without thorough cleaning, the application of a special dry coating will not be resistant to corrosion processes.

You can create a power frame from. These viruses have been introduced recently, and there are no standards, supported by a wealth of practical testing. It is also necessary to take into account the diversity of the combination of glass, carbon and basalt in combinations with plastic.

Such fittings are less comparable to their metal counterparts. After this, it does not create a “place for cold”, which thereby enhances the insulating characteristics of the structure. Other “pluses” are re-indicated lower:

• Polymer-based composites are not threatened by corrosion. The stench decreases approximately 3 times, the lower metal parts have the same diameter, so apply force for stretching.
• The extra advantage is not a big one. Light rods are easy to transport and dismantle.
• There are no traces on them, so after completing the installation operations the clothes will remain clean.

• Reinforcement with sloping plastic has less spring. They cannot be bent to a small radius without damaging their integrity.
• It loses its value when heated.
• Several modifications can improve the furnace process.
• You can't connect.
• There are still no technologies that are based on precise developments and confirmed by solid evidence.

See you home! These shortcomings can be called intelligent. The strength of the welded seams is more clearly seen. Skloplastik does not carry out an electric jet, but at the depth of the foundation it is not of great importance.

You will never be able to clarify the identity of the gate after a visual inspection. The very advantage of this is to provide products from domestic producers, which are confirmed by official certificates. This hardening, however, can be applied to all types of reinforcement valves.

Scheme of reinforcement of a strip foundation

Since there is no professional project approved by an architectural bureau, you can use such information. The stench will help to develop the structure of the armature and other light household items. These rules can be updated during the development of metal viruses. Having chosen composite analogues, you will need to make specific corrections to ensure proper results.

Below are the specifics of the technology:

• The later elements of the structure are subject to maximum stress. Here you can find lozini with a diameter of 10-12 mm.
• For vertical and transverse sections, reinforcement with a thickness of 6 to 10 mm is suitable.
• The small space between the surrounding elements has been created. For larger distances, choose rods with a large diameter or change the diameter.
• What is more important is the expansion of the reinforcing frame in the middle of the concrete block. To the outer surface from the new hour of pouring, maintain a distance of 30-60 mm.

More handily and more handily, you can remove the required data for help. Such calculators are sold at no cost by sellers of fittings and other websites (not our fault).

This is due to the understanding of the underground waters, the depth of freezing and the level of ground waters, and geological data. Such tasks must be entrusted to specialized fakhivs, since the work of the object is transferred, which exerts more than 40 kN per square meter. the surface of the land plot.

In order to independently create a reinforcement cage for a string, standing or finger foundation, a mesh for a floating slab, you need to learn how to correctly knit the later and cross-sections of the strings. For this, it is enough to have a self-sufficient or factory tool and know the schemes for installing reinforcement in the middle of concrete structures.

The most recent recommendations on how to knit reinforcement by hand were provided by a contractor from the project in 2007 at the Institute of Reinforced Concrete Construction named after Gvozdev. The knitting thread conforms to GOST 3282 (available with coatings of 0.2 - 6 mm and without any 0.16 - 10 mm), since not every thread that is in the reign of the home master, after falling becomes soft, preserves characteristics m_tsnostі.

Fakhivtsi do not recommend the use of plastic clamps, because when the concrete is moved in the middle of the formwork, the joint will shift at once. For slab foundations, the industry produces ready-to-weld reinforcement mesh, which is more expensive to deliver to the site due to smaller bars.

In addition, the ends have to be filled with P-like elements by hand. Therefore, for minor tasks of reinforcement work in individual everyday life, a knitting bolt, a hook and the given instructions are completely sufficient.

The technology for knitting reinforcement correctly involves the following sequence of operations:

• from the bay, a piece of 20-25 cm is cut for rod diameters of 8 – 16 mm;
• it bends completely, starts when the rods are blown diagonally;
• the sting of the hook is pulled into the loop;
• the trembling clamp tightens;
• The outer edge is placed on the stock of the jack;
• The tip wraps of the tool are twisted in 3-4 turns;
• after the tension is tightened, the free ends are pushed out into the middle of the frame;

This technology is suitable for all foundations, including the schemes for moving the struts in the middle of the reinforcement structures.

Important! When the reinforcement is 25 mm thick, weld the sticks with adhesive wash. Tied with tiny twists, the intersections in this form can become creased under the weight of the construction material.

Stitch foundation

Before you build a frame from reinforcement for a stitch foundation, you need to understand the basic requirements of independent foundations:

• the straight rods at the corners are overlapped;
• frames stand on concrete bases on vertical struts;
• for cross-cut concrete structures, reinforcement is less than 0.1%;
• The dry, dry ball is not safe, the darts are sticking together on the large plots with formwork.

It is not possible to reinforce the corners of a strip foundation simply by overlapping the rods. The reinforcement is carried out using special anchoring schemes, directed below.

When reinforcing the lines, ensure the particularity of your foundation:

• when concreting MZLF, the reinforcement cage can be tied in the middle of the formwork, vikorist strips, clamps and anchors;
• The deep-laid lines are reinforced before installing the panels; splinters can easily penetrate into the middle of the formwork;
• frames can be prepared in the formwork, placed behind the frame in the formwork, and then reinforced with L-like or P-like anchors in the corners;
• footing reduces the minimum size of the dry ball on concrete under the base of the structure from 5 cm to 2-3 cm; To create the lower dry ball, special plastic stands - “flasks” - are used;
• when extending later rods, it is necessary to ensure an overlap of 20 diameters of the reinforcement, or not less than 25 cm;
• It is prohibited to lay the lower belt on a stone, a platform, scraps of reinforcement, including plastic or concrete pads are allowed;
• connecting the reinforcement overlapping the cores and spreading them apart, so that in one section more than half of the sections of all later reinforcement are not connected.
• It is based on the minimum height of the reinforcement at the transverse section of the cross-stitch foundation, which is more than 0.1%;

Schemes for reinforcing the corners of a stitch foundation.

Important! Clamps (transverse horizontal and vertical rods) are mainly necessary to give the frames the necessary spacious geometry. Therefore, the reinforcement is important for its design, but it does not bear any stress during operation. The diameter is taken to be equal to 6 and 8 mm for less than 80 cm and more than 80 cm.

Slab foundation

The fragments of the slab that floats are impacted by the road foundation; in the middle part of the structure, discharged reinforcement can become damaged. However, this method of saving materials will require professional development in special programs. Therefore, individual contractors most often use reinforcement mesh with the same middle.

Correctly knitting reinforcement into meshes is not difficult, however, amateurs, rather than relying on knowledge and profile lighting, indulge in the following:

To assemble the reinforcement frame of the slab, the upper mesh must be fixed on the support above the lower chord. For which tables, toads, spiders, and other elements with curved legs for spiraling onto the lower middles, policemen to support the upper ball are used.

The spider is made from reinforcement with a diameter of 8 mm.

When the fittings are damaged at the site, it is prohibited to heat the rods in gas boilers. It is our responsibility to use the necessary versatility or clips to ensure the required radius of the vehicle. In places where load-bearing walls are being removed, the slab foundation is reinforced with additional reinforcement, then. The cooking time changes twice a day.

The slabs with reinforcement ribs under the walls, which are to be supported, have frames built in analogy with the foundations and grillages. They are tightly knitted with mesh slabs, providing standard dry balls for concrete.

Grillage

The similarity between the grillage and the raft foundation leads to independent reinforcement. The stitching indicates stretching in the sole of the cottage, and in the upper part due to the heaving of the soil. There is no force on the grillage, the fragments of wine are reinforced in the ground with a ball of expanded polystyrene, which is crushed, or with a clear gap of 10 - 20 cm. orthogonal pinching of the posts into the beams.

Important! For a grillage, it is not enough to build a standard frame from later shears tied with clamps. It is necessary to additionally strengthen the top row of columns (palettes and stovpi), the entire lower belt.

Scheme of the correct reinforcement of the unit for obtaining a grillage/firewall.

Recommendations on how to knit reinforcement bars correctly are used only with steel rods. It is not recommended to install composite reinforcement in foundations, as when tension appears, it will stretch out, and then the tension will begin to be absorbed. This can lead to the opening of cracks at the bottom of the upper part of the concrete foundation beams, from which the grillage is formed.

Stop and fall

The design of the frames that are erected in monolithic reinforced concrete slabs and slabs is similar to the reinforced belt of the stitch and grillage. The shape of the cut can be of several types:

• with vertical tubular formwork, it is possible to create a square or round frame;
• When all parts of the foundation are poured into the panel formwork, the clamps for connecting the vertical struts are made into a square or rectangular shape.
• The minimum number of late rods in one stack is equal to 4.

Knitting a frame for pali.

The lower part of the rubble concrete slabs is not reinforced, because the rods are used to lay the middle of the formwork of large stones. The heads of the rubble concrete pile (1 m in height) are filled with ready-mixed concrete and reinforced with a short frame.

On vertical cuttings, legs are inserted under the straight cut for a tight connection of the posts with the beams of the grillage. In this case, some of them are guilty of being tied to the lower belt, which they lost to the upper one.

Build the frame best on your own, using vikorist and darting twisting. In ready-made products, which are produced for all parts of foundations, drilled pins, all welded materials. This is due to the high technological level of welding in rustic wood with wood lashing.

In this way, you can correctly knit the reinforcing mesh and frames yourself at the seams. For the skin type, the foundation has nuances that change the meaning of the dry ball and concrete. The most difficult moment is the anchoring of the corners, strengthening of the pushing and stretching zones.

The integrity and correctness of the reinforcement frame contain many indicators of the value, reliability and durability of the foundation support structure. The reinforcing belt can be seen as a kind of skeleton, which corresponds to a real increase in the strength of the base to the desired effect.

In preparation for the future pouring of the foundation, it is necessary, first of all, to consider all the reinforcement and optimally integrate it into a similar structure, otherwise, in some way it is possible to ensure the connection of adjacent elements into a single frame.

You are encouraged to learn more about the safety precautions and important related nuances below.

Diameter

When choosing reinforcement for the foundation, we first pay attention to the diameter of the rods. The principle is simple: the more common the fittings, the more serious needs they have to show. When the optimal diameter is determined, first of all, the characteristics of the soil (the main moment - heaving) are taken into account and the finished spore is transferred to the mixture, the internal lining and the bags/outlets.

Reinforcement diameter, weight, total cross-section area

So, ideally, you follow the rules. Along with this, a lot of private forgettings are evident from the development of project documentation and the identification of related great developments, reaching the averaged and generally accepted values. As long as there is a lot of daily life in small situations, for example, such as climbing, such an approach is acceptable.

Class

Another important indicator is the reinforcement class. For an individual foundation, choose material class A-3.

Corrugated fittings A3, steel grade A500S, GOST 5781-82

The reinforcement of this group is easy to use (it is easy to bend without the need for special tools), the value is reliable. It is better to use rods of class A-2 (they can be bent by 180 degrees, A-3 – by 90 degrees).

Material

An equally important display is the preparation of fittings. Previously, there was no need for regular food - the rods were made from stainless steel, there were no alternatives.

The future market is constantly developing and expanding. One of the confirmations of this was the appearance of plastic fittings for sale.

These groups are characterized by improved operational and practical characteristics. In the middle of the main transitions of the skloplastikovy reinforcement, the next moments will be indicated:

• high indicators of reliability, value and durability;
• equal to low varity;
• the vaga is small.

The use of flexible plastic reinforcement allows you to save on average up to 30-40% on purchased and transported material for plating the reinforcing frame aligned with traditional steel elements.

The small size of the plastic reinforcement makes it possible to transport it in a simple passenger car. The reinforcement does not need to be demarcated until the end. To cut lozin, use a grinder first.

Important! In front of the sharp plastic reinforcement, put on dry overalls, gloves, eyepieces and a respirator.

Composite plastic fittings of different diameters are available for sale, which translates into different knitting options. It is important for late reinforcement to be 8 mm long, for transverse reinforcement - 6 mm.

The fastening of skewed plastic reinforcement is most often made in 2 ways:

• for additional help with the tying rod;
• for additional plastic clamps.

The procedure for implementing both methods is identical for steel and fiberglass reinforcement and will be discussed in the following sections.

Drill, clamp, retainer: features of basic fasteners

The fastening of reinforcing bars into a single frame can be formed using stiffened rods, clamps and special fasteners. There is a table about them.

Table. Materials for fastening reinforcement

Bonding material	Description
	The most traditional, budget-friendly and basic (especially for “old school” workers) material for knitting reinforcement. Made from singed steel. It is important to sell “wholesale”, that is. in packages (more robust, since the material has already been cut into uniform strips) or in special spools. The packaging and the final round of fruit can be changed depending on the vibrator. The most convenient ones are 5-kilogram packs filled with 40-centimeter cut-outs. One such package should contain 1000 to 1500 pieces of wood.
	The principle of knitting has little to do with knitting - the same methods, similar tools. The twist is characterized by great strength (it’s easier to bend and twist). The pieces are more expensive, but they are less expensive. It has a larger diameter (4 mm in diameter versus 1.2 mm in white). To ensure reliable connection of the reinforcing bars, it is enough to twist a 20-centimeter clamp onto one point of the crossbar.
	The most current option for connecting reinforcing bars. Fixators are made of plastic. It is best to show yourself in a complex with plastic reinforcement. The advantages over steel reinforcement and knitting dart are obvious. To make them aware, you need to pay attention to just 1 piece of steel reinforcement - it is susceptible to corrosion. It is designed to increase the diameter of the metal rod by an order of magnitude. This value, however, is not changing for the better. Corrosion should be brought before concrete appears. Water penetrates at the pore. As the water freezes, it expands and the cracks become larger. The fasteners do not rust, and connecting to additional fittings is much simpler, easier, and faster. For sale there are a number of different types of fastenings that allow you to securely connect reinforcing bars in various wide areas, plaster “supports” (as in the picture) and fix other problems connected s armuvannyam.

Looking at those who look at the care associated with the knitting of the reinforcement itself, the order of connecting the rods with special fasteners cannot be seen - this process is not connected with the traditional understanding and in general truly intelligent.

Give the rod and clamps more respect.

First of all, drit.

For the production of such, as intended, low-carbon grades of steel are used. The flammable material is remarkably easy to bend and efficiently copes with the tasks that are placed on it. We sell available non-galvanized coatings in a knitting pattern (black color) and similar galvanized coatings (white).

Many fahivts advocate the purchase of a galvanized knitting rod for finishing the foundation due to the superhumanity and ineffective waste of the foundations, arguing for their position by the fact that the reinforcing frame after pouring concrete becomes inaccessible to the wind, also, etc. there will be nothing to live. However, it is not possible to turn off corrosion, as was stated earlier.

• If you decide to knit steel reinforcement, you can knit it with both galvanized and non-galvanized wire - if corrosion will occur to the reinforcing frame, it will be the same, whether the reinforcement, or the damage, and The basic characteristics of the foundation for such furnishings are not give in. ;
• Yakshcho Vikorishino Vikoristovati to Znplastikov reinforcement, more painfully the health of the gap, the gap of the Tsomo will be the trivial Trival Termin of the Open Structural Service,

Depending on the diameter, the most optimal for ease of use and reliability is the 1.2-1.4 mm option. “Single” is weak for the foundation; work with “double” will attract a lot of attention.

In other words, clamp.

This, as it was meant, is an improvement and reduction in the knitting option. They are made from plastic, not steel, so when such fastenings are removed, the risk of corrosion in the middle of the supporting structure is turned off. In addition, through the material used to make the plastic clamps, many of the clamps suffer from a low supply of power to secure the entire group.

1. How can clamps be placed on the vantagement that is created in the middle of the foundation? You can.
2. Why won’t the fastenings rupture over time, destroying the uniformity of the structure and ruining the foundation? Chi will not burst.
3. Is the plastic clamp really reliable? True, but you need to go to your choice correctly.

Corisna is pleased! For knitting reinforcement, it is best to use plastic clamps with a vikoristan steel rod as a core. Such fasteners are more expensive to construct, lower steel wears out, and they do not pose a problem with handiness in work.

Important note! Plastic clamps cannot be used for knitting reinforcement when working on the foundation in the winter - in the cold, the material of the fasteners almost becomes brittle. Vinyatok are special fixatives made from polyamide.

First of all, remember the rule: the fittings are not connected to the welding material, but are connected themselves.

Connection of fittings - diagram

The bottom line is that the contact between the metal and the electrode causes a change in the value of the first layer, which brings about the importance that is expected with minimal possible shrinkage of the foundation, which can lead to catastrophic consequences, after The ice age of them is as follows:

• the place where the fittings are connected will collapse;
• the reinforcing frame falls apart;
• The concrete structure begins to crack.

No comments will be required regarding this threatening the information on the foundation of the structure. As the fault can be seen only in special reinforcing bars, the technology of preparing them according to GOST immediately transfers the possibility of further welding.

In another way, vertical support rods, which are installed as supports for horizontally oriented rods, cannot simply be driven into the ground. The correct way to work is this: the lower reinforcing row is laid on special plastic fasteners (the so-called “clamps”, demonstrated earlier), and the upper part of the vertical runners is connected to the upper row of the frame. By placing this way, turn off the contact of the rods with the external core.

Thirdly, the upper horizontal row of the frame must be tied in the middle - this is more foldable and more correct. Often, uninformed forget-me-nots are allowed to make adjustments, leaving the top row of the frame unfixed. If the concrete is poured by hand, nothing terrible will happen in such minds. When pouring with a special concrete pump, the mixture is fed under a pressure. Open the vise until the reinforcement is pulled to the sides, so that it may become loose.

Fourthly, during reinforcement it is necessary to pay special attention to the corners of the structure, because The stench itself is the weakest link to the foundation. In such plots, the ridges do not fit under a straight edge, but bend. Overlap when they hang in the wall. It is important that the reinforcement bars do not overflow at one point. The principle is demonstrated in the image.

The correct consideration is the reinforcement, which results in a rigid, spacious frame that shows the air of people without visible changes in the structure.

For knitting reinforcement, you can use a wide variety of devices - from pliers to special automatic guns.

Using sharp pliers and a wire cutter with teeth that are blunt in front is the best option. Its only advantage is the need to purchase additional attachments and tighten them with similar improvised methods for a long time, manually and tediously. That’s why we lose sight of their gaze.

If you are on a tight budget, you would like to get a basic hook for tying. For this you don’t need anything other than a piece of 4-5 mm diameter, a blank for a handle or an old unnecessary screw/sew and hammer.

To prepare the gachka, do the following:

• prepare your pen. You can use any type of wood to prepare (wood is easier and easier to hammer in flowers), for example, using household tools to serve your purpose. The handle can be made from other materials, brand, so that you can handle it manually;
• beat the flowers into the handle, leaving 3-4 cm loose;
• hold a drop of flower, for example, using a plier or other similar device;
• Bend the flowers from the gutter. It works like this: you place the flowers on a supporting stand, for example, a sheaf, and using a hammer, press the prepared hook into shape for knitting.

The procedure for preparing a hook from twisting/sewing is reduced to the final stage of the induced process. At the exit, you must remove the attachment that may be approaching the appearance.

Knitting with a heavy gag

Having prepared a self-made tool or bought a ready-made tool from a government store, proceed to the finishing work. To begin with, carefully practice on third-party fittings, but do not thoroughly explain the principle of operation. It lies in the future:

• a piece of knitting material with a length of at least 200 mm is folded all over;
• When cut, the workpiece is wrapped diagonally at the joining point;
• The hook stretches around the closed loop;
• The loose ends of the knitting needle are carefully pulled through the loop. At this stage the hook also helps;
• If the working tool is not removed, turn it behind the year arrow until a reliable connection is released. Depending on the number of turns (up to 3-4) turns. It is no longer possible to twist the thread - it will break. Bend all parts of the ends of the wood. If the ends are too long, you can cut them with wire cutters or other similar tools.

p align="justify"> Schematically the process of representation on the next image.

For a quick understanding of the technology, take a look at the step-by-step illustrations.

There are a number of other options for knitting reinforcement with a hook, but if there is a better way to install it, it is recommended to stick to it yourself.

He also shows himself a nasty way, which is why the Vikonator is guilty of consistently viconting such manipulations:

• fold the cut in half, like at the front cut;
• place warehouses under the fittings at the connection place;
• tie the noose with a hook;
• bend the “tail” through the hook so that it becomes loose;
• tighten the loop.

The procedure for completing the work is clearly demonstrated in the following illustrations.

Knitting with automatic stitch

The automatic, reversible and screw-type crank is a sophisticated and manual version of the sophisticated attachment.

The length (as a rule, it is 32 cm) and, in general, the special design of the reversible hook allows you to securely twist the bolt in one tightening. A soft hand with a gum and a robot with a tool is still handy and safe, but the culprit is the culprit of calluses on the hands.

The order of this kind of attack is:

• From now on, circle the reinforcing bars with a dart at the junction point (the procedure is the same as for every emergency emergency, all necessary information was provided);
• The hook is inserted into the loop;
• Finally, pull the handle of the instrument towards yourself.

That's all. As a result of such simple actions, the device, which works similarly to the “yule”, quickly tightens the flow, ensuring the removal of a strong, reliable and neat knot. The laboriousness and spending an hour on research will make the work quicker.

The tool is suitable for both professional and private writing. The reversing crank does not require any special technical maintenance - all you need to do is periodically lubricate the working elements with oil.

The principle of operation of the screw hook is demonstrated in detail in a video recording.

Video – Knitting with an automatic stitch

Hand-knitted with a stitch - it takes a long and laborious approach. And although the automatic hook, seen in the front section, makes it easier and quicker to install reinforcing robots, there is a wonderful opportunity to do everything richly and with even less effort. You can also use a drill/screwdriver to help.

All you need to do is prepare a latch (as a workpiece with a diameter of 0.5 cm, according to the principle of preparing a latch, you have already learned in one of the front sections) and fix it in the cartridge. screwdriver in the same way as the original drill bits are installed (details The sequence of replacing the working tool should be specified in the instructions directly from your screwdriver, since for different models of tools these moments may vary significantly.

Look like this design will be in this way.

The following procedure has no bearing on the technology of tying the reinforcement with a hook: you just fold the two pieces yourself, place them under the reinforcement, hook the loop with a hook, and then twist it not by hand, but with an additional screwdriver, reporting minimal effort.

When the drill is tightened, the tool practically does not recognize pressure, so for knitting you can use the most budget drill-screwdriver with minimal force. Better yet, the boule model is equipped with a wrapper regulator. In front of the robot, show yourself yogo shonaymenshe.

The gun can be used to knit the reinforcement as smoothly as possible, either simply or manually - the most sophisticated models of such guns can be assembled in less than a second. No preparatory steps are required: after winding the gun around the spool, the operator simply brings the tool to the connection point and presses the corresponding button. For information on special options and functions, please refer to the instructions for the specific tool.

It looks like this.

There is no need to cut the wood before working: you can make all the tools yourself. This is a great advantage - the output from the appearance of cuttings from knitting is daily, which is why the amount of incomplete expenditures and working expenditures changes significantly.

The gun is hand-held by the robot - it can be trimmed with one hand and the other, while holding the reinforcement frame, which makes it difficult to obtain additional working force from the eyes of the handguns.

An automatic gun, instead of hand tools, allows you to develop a consistently high knitting strength. All models have the function of adjusting the tension and tightening force.

Pistol brand	Vaga	Size of fittings	Price
	1.4 kg	D19xD18	48780 rub.
	1.5 kg	D20xD22	60920 rub.
	2.25 kg	-	52,000 rub.
	2.4 kg	Width 20 to 35 mm	165,000 rub.

Among the shortcomings of the automatic gun for knitting reinforcement, you can see the following points:

• high quality of the tool and components (spool with dart);
• the need to first start working with a pistol (with nothing foldable, otherwise the additional hour is still spent. In practice, this is overcompensated by the savings in time spent on rolling the dart);
• the impossibility of using a pistol in highly accessible places. You may be a serious knitting machine, but you still won’t be able to fully cope with the stagnation of hand tools for knitting. For example, you won’t be able to use a gun to tie the rods in the coils of a reinforcing frame. Finally, you can insert the hook between the whips to attach the 2nd ball of the folding frame.

A few words about clamps

For knitting reinforcing bars, as intended, you can use special clamps. The stink looks like this.

In this way, one end of the clamp is loose, and on the other the retainer is loosened.

The order of the attack yoke is:

• the vibration will start under the reinforcement strips at the place of the cross;
• The free end is pulled into the opening of the fastener until it stops;
• The position of the fastening is fixed, which ensures the connection of the fittings.

There are many different types of clamps on sale. The most commonly used reinforcement complexes are those made from polyamide 6.6. Such clamps normally “feel” in a temperature range of -40-85 degrees, without bursting, cracking or spreading. A good clamp is elastic. You can check this parameter like this: select the selector and turn it down. As soon as a crack appeared at the place, it appeared as if such a clamp was being removed.

There are special guns available for sale that allow you to carry out the process of cleaning clamps more easily and quickly.

Metal fasteners (connectors) can be added to similar fastenings to connect the reinforcing bars into a single frame. One end of such a mesh is equipped with a hook, the other with a loop. Set the diameter of the steel violin to an average of 2-4 mm. At the place where the reinforcement is connected, the hook and loops are secured to the lower steel bar. The middle part of the clamp presses the upper rod to the lower one.

The life of a hut begins with the laying of the foundation. The main thing that appears to be a foundation of concrete is its importance. There you can reach a frame made of reinforcement rods, tied together, laid in the middle of the concrete. Such a frame is called reinforced. This article deals with such an important stage of civil work as the binding of reinforcement for the foundation.

It is necessary to take a closer look at how we have begun to discover the methods of knitting reinforcement for the foundation. The stench differs among themselves according to the type:

• tool;
• material;
• knitting schemes;

By type of tool This can be done either by hand knitting reinforcement for the foundation or by using a special tool. How the rest of the vikors are special knitting hooks, screwdrivers, special guns, which are released for this particular operation.

Yak material, which is used for connecting reinforcement rods with each other vikorist:

• knitting drits— this is the broadest and most advanced technology of associated reinforcement for the foundation, which is connected to the associated unit.
• violins- with hooks at the end, as a substitute for dressing with a knitting arm, knitted without tying a knot.
• clamps small in size Made from plastic- This new material has increased ease of installation and high elasticity of knitting, and is also not afraid of corrosion. However, such a connection of reinforcement for the foundation evokes great skepticism among professionals. Read the report.
• clips- vikonani in the form of clamps that fix the connecting rods to each other.
• zvarne z'ednannya- This old method does not gain expansion, fragments of the welded joint, due to its crispness, are susceptible to cracking when poured with concrete and do not lack the necessary reliability. A highly qualified welding specialist is required to make an acid welded joint.

Necessary drit

When choosing a drill, it is necessary to consider the following factors:

• Manufacturing accuracy class. The accuracy class is determined by the production method. This is due to the high class of accuracy, which is a variation of the actual size, diameter, as declared by the manufacturer throughout the entire year, which is smaller than that of the lower class of accuracy. However, for knitting reinforcement, the accuracy class is not of particular importance.
• How to rent a dart. There are two types of rolling: cold rolling and hot rolling. Cold-rolled steel is pressed from blanks without heating. With the hot-rolling method, rolled steel is rolled into a heated mill, which provides greater value.
• Which group should I pay attention to? drіt (the first and the other group is sleeping);
• Corrosion resistance level. Behind this sign, there is only one difference - that the coating is galvanized on the surface.

The criterion for choosing a dart is very simple, required drit, which is called “knitting”. It has a new set of necessary characteristics: sufficient softness when applying value, resistance to abrasion and reliability of fastening.

Galvanization is respected above worldliness.
The optimal diameter of the knitting needle is 12-14 mm. A lot of strength is used on something with a diameter of 1.6-2 mm, as a result of which the everyday life becomes calm, and one is too weak, it just shovels.

Respectfully It is necessary to stitch so that the connected reinforcement after tying the knot becomes rigid: before the hour of pouring, the frame is liable to become indestructible. This ensures the reliability of the structure after being caught.

You need to check the rigidity of the connected fittings using the threaded rods - if they are firmly fixed, then they won’t walk, anyway. There is no need to try the vuzol itself, otherwise there is a risk of developing a binder.

Dovzhina dart, it is recommended to use one tying point, set at 30 to 50 div. The cost itself is extremely cheap - about 50 UAH. for 100 meters. To avoid shortages at an unexpected moment through wastage or loss, it is recommended to purchase them with an extra supply. 100 rubles for 200 meters is not at all inexpensive.

How to bend reinforcement correctly, all the ways

Choose how to bend the reinforcement for the foundation of the track beyond its diameter: with your own hands The small diameter can be easily bent, and the axis for the same fittings can be achieved use special devices, either self-made or specialized.

The middle of self-made devices can be expanded in two ways. The first is when the original pipe of the same diameter is installed vertically and the base is filled with concrete so that it stands perfectly.

The fittings are inserted all the way into the middle, and now the end that protrudes from the pipe can be bent, simply pressing on it. If you want to install the folding pipes, then put additional pressure on another pipe on the free end of the reinforcement, and now, using extra strength, calmly bend the entire reinforcement.

They also often go out to help with cooking. Once the wood has softened, it can be easily bent when heated. You should also hesitate to use a blowtorch and a hammer. After heating the point with a lamp, bend out the reinforcement with a hammer.

The most radical way is to make an incision with a small grinder and then bend the surface using other tools.

It should be noted that the methods of welding and cutting are not the shortest - in these cases the value of the reinforcement is reduced by up to 10%.

Knitting with slack

Vikonannya gachka for these purposes may be different, but not so important. The sense lies in the obviousness of such a thing, so that for the help of someone else he is reaching out. The rules for knitting reinforcement for the foundation are shown schematically.

Revert to the sequence of actions:

1. It's burning completely;
2. Along the arrow, like a baby, place it in a stretching position;
3. Stick the hook in the loop and it will start right away;
4. Pull the loop through the middle between the loose ends of the drawstring;
5. Do not hold the hook, twist until it is tightened, but do not over-squeeze;
6. Ready!

There are mechanized screw hooks, which have to be pulled for the additional wrapping of the screw. It’s very easy to come out.

For stitch foundation

The reinforcement of a string foundation uses two schemes for laying rods:

• system with 4 rods: two at the base of the foundation, two at the top (to be corrected, if the width of the foundation does not exceed 50 cm),
• system with 6 rods: the additional late cutting is laid between the two main ones (staked at the ends if the width of the foundation is over 50 cm).

Bent reinforcement is placed on the corners, and at least 40 cm protrudes from each end of the pipe. Vuzli connection of fittings guilty will be dealt with one way at a time on the rise no more than 60 dart diameters. For example, if 12 mm reinforcement is used, then the skin is bound to 72 cm or more often.

For stovpfrequent

This is the foundation that is placed on the steps, which marks the role of the fingers.
The middle of the stacks is knitted before pouring. The tying of reinforcement for a regular foundation is the same as for a string foundation - either 4 rods, or 6 for foundations of a large size.

For vertical shears of this type of foundation, 12-millimeter reinforcement is used to vikorize the vertical foundation. Cross haircuts can be thin and smooth.

For wooden booths, it is allowed to vikorize the bottom and vertical reinforcement thinner than 12 mm. Sometimes, for the foundation of small buildings made of wood, a welded frame made of vertical rods, tied with hoops like a barrel, is used. This is wrong, since this method of binding can only lead to welding, but it is not a very reliable method. We've already talked about the price.

For slab

The frame with reinforcement for the foundation can look like a two-dimensional surface, a mesh formed from reinforcement rods. Another option is volumetric, in the form of two meshes with reinforcement that intersect, one extended above the other and connected by transverse rods.

Fittings - 12 mm or even more, up to 16 for private households. The size of the center of the mesh should be 200x200 mm. The distance from the lower reinforcement belt to the pillow (or insulation) is 50 mm. The upper belt is also protected from external influences with a 50 mm ball of concrete.

Rozrakhunok vartosti (price for work and materials)

We will take a 10 by 10 meter foundation for the butt. This is the perimeter of the booth. In addition, there will be a foundation for the internal walls that will be supported - two walls of 10 meters each. Exit 60 m.p. foundation.

How much work is required for the correct approach?
It is permissible that the foundation is less than 50 cm wide - in the future, a scheme with several late grooves will be used. In this case, in 1 linear meter of the foundation we will vikoristovuvatimutsya:

• 4 late rods. That means at 60 m.p. will be 240 meters.
• 4 vertical. If the height of the foundation is, say, 50 cm, its height will be no more than 45 cm.
  4 x 45 cm = 1.8 m. For 60 meters to the foundation - 108 m.
• 4 cross. With a foundation width of 45 cm, the width of the transverses should not exceed 35 cm.
  4x35 cm = 1.40 m. At 60 meters the foundation is 84 m.

How much will it cost?

For late vines we use 12 mm reinforcement with a diameter of 25-30 r/m.p. 240 x 35(30) =6000 (7200)
For vertical and transverse rods, use 6-8 mm with a gauge of 12-16 r/m.p. (108+84) x 12(16)=2304 (3072)

So, the purchase of reinforcing rods for this foundation will cost from 8304 to 10072 rubles.

Now we need to take care of the necessary strength dart. 4 ties for a 4-rod foundation per 1 m.p. This is based on a maximum expenditure of 50 cm per tie, 2 meters per meter of construction. We have 60 meters, so obviously we need 120 meters.

Uvaga: It should be sold in kilograms. It is necessary to convert from meters to kg.

1 m shot with a diameter of 1.2 mm weighs 9 grams, likewise 120 m shot with a diameter of 1.2 mm weighs about 1 kg, which costs about 50 rubles. There are a lot of copies, so you can and need to take it from a double reserve of -240 meters for 100 rubles. As a rule, it will not be fully insured and will work from pouring the foundation. In the regions, such robots are cheaper to construct, but the price increase is approximately the same - 1000-2000 rubles per cubic meter. This price includes cutting trenches, installing formwork, tying the frame, pouring concrete and removing formwork.

The foundation is laid down to cover 60 meters, width 0.4 m, height 0.5 m. Calculate volume: 60 x 0.4 x 0.5 = 12 m3. For such an obligation, the cost of foundation work in the warehouse is 12,000 - 24,000 rubles.

The reinforcing frame in the middle of the foundation is a structure that is designed for strength and tension. Even concrete under such pressure becomes covered with cracks, and in the end it simply splits. Therefore, the reinforced frame is necessary, that invisible part of the foundation. In this case, the connection of the rods with each other must be carried out not by welding, but by dart.

Because when boiled at high temperatures, the crystalline burrs of steel change, which leads to a decrease in the value of the product. Therefore, the lesson on how to correctly knit reinforcement for the foundation is now relevant for those who are trying to fill the foundation of a booth with their own hands. Let's look at all the processes in the report.

Vikorystuvani vidi

Before starting to analyze how to properly tie reinforcement for a foundation, you need to look at the reinforcement itself. Today, the market offers two types:

1. This is of utmost importance.
2. Composite.

Vikoristov’s mustache has been ringing for a long time. Although it is a different model, the one below differs from the first one, and is even shorter.

Staleva

Metal reinforcement – ​​there are six classes, each of which is divided into hundreds of additives to lay it down. And the more of the others, the greater the class, the greater the characteristics.

The reinforcement rods themselves are darts with a smooth or corrugated surface. First class – smooth, other corrugated.

The relief structure means an increased surface area of ​​the reinforcement with the concrete break. Before that, the functions of the sides begin to emerge, which must be streamed when the reinforcement structure begins to stretch.

Since the choice depends on the quality of the reinforcing rod, then for the foundations, hot-rolled material of class A III with a diameter of 10 - 18 mm is used.

Cutters with higher performance characteristics and dimensions are more expensive, which means they sacrifice the same functions with little need. And for the lower class, the reinforcement for foundations is weak. If you need to add what’s in the frames, what’s being reinforced, smooth reinforcement is being cured. It is not the main one, but for jumpers, crosscuts, connections and other nodes that are not secured, but stagnant.

When choosing a track, pay attention to the labeling process, especially the index. There are only two axis:

1. “C” means that the reinforcement can be welded.
2. “K” - anti-corrosion additives have been added to the steel. This type is the most expensive, but in a private home there is no vikorism.

Since there is no need for welded reinforcement, it is also not the cheapest option. Therefore, for private owners, the best option is knitting with a steel dart. If the food is good enough, what kind of dart is used to fit the reinforcing frame, then it will be lower about Rozmov.

Composite

This variety contains very new material. It is based on plastic, into which the components are added to form it: rock, coal, basalt.

The most popular is the skloplastikovy variety, because it is simply cheaper than the other two, practically with the same characteristics of value.

If we talk about the technical characteristics of this material, then:

1. The tensile strength of plastic reinforcement is 1000 MPa, and that of steel reinforcement is 390.
2. Vaughn laid down for the metaleva 3.5 times.
3. Steel is corroded, plastic is resistant.
4. Please do not carry out electric shock.
5. It has low thermal conductivity.

If there are negative sides, then:

1. Metal reinforcement has a spring resistance.
2. Plastic is included in the category of low-flammable materials.
3. When heated, the wine softens.
4. You can tie skloplastikovo reinforcement only with clamps or a dart, steel can be welded.

Drit

For reinforcement frames, it is necessary to comply with standards issued according to GOST 3282-74, which indicates that this material is classified according to decal positions.

1. Processing method: uncut or singed.
2. Cutting accuracy.
3. With or without zinc coating.

The diameter of the vibrator varies in the range of 0.16-10 mm. You can choose a black color or a steel one. So, as we say, the knitting dream is that, with the great cycle of death, it is better to choose the burning option.

What we can say is that galvanizing is designed to last a long time, and no one will interfere with it. Although it is more expensive initially, in the middle of hardened concrete, corrosion processes practically do not occur.

To knit a reinforcing frame for foundation structures, vikorist is used with a drill with a diameter of 1.2 - 1.4 mm. above 1.8, because the diameter of the reinforcement rods for the frame is the largest (18 mm).

Today, coils of knitting rod have appeared on the market, with a cut length of 80-180 mm, and loops have already been cut at the ends. Then the sections are ready for knitting. In one bay there are 1000 streams.

Its advantages and shortcomings

The connection of reinforcement for the foundation in the first place is determined by the characteristics of the foundation. This is the main advantage of the reinforced frame. However, other positive aspects of the design are indicated by the knitting of the dart.

1. The joint with a dart preserves the volumetric and linear shape of the frame structure.
2. In this case, the connection is not fixed properly, so as to avoid welding. There is no place for balancing the reinforcing bars with each other, which is very important when pouring, vibrating and breaking concrete. Thus, the connected reinforcement allows the ability to move by millimeters in the area of ​​binding, taking an ideal position when attached to the side of the concrete mix.

Although there are a few shortcomings, the stench is mainly due to the time-consuming characteristics and laboriousness of the process itself. To cook the frame shvidshe, knit the bottom with a dart. And there is a difference here. Tying the reinforcement cages to the foundation is not easy on the right. Here you need to know the methods and use a special tool. Although, as practice shows, a number of knots already provide the necessary evidence that changes the foldability of the knitting, and the hour it takes to complete it.

Yak v'yazati?

There are a number of options and schemes for how to tie the reinforcement manually. You can’t get your knitting fingers through the harshness of the dart itself. For this process, various tools and devices were found. Knitting is carried out with a slack (either self-propelled or factory made), using an automatic slack with inertial action, or pistols. Maistri navit dril was used for mating. And as a knitting material, today’s metal staples, clamps or drippings are used.

Tools

Tying reinforcement to the foundation involves assembling the frame into a single structure. All the meanings of the tools have been studied for a long time, and the knitting schemes have been figured out since then. So let us first look at how you need to master this simple tool.

Gachok

Making a hook for knitting reinforcement with your own hands is not a problem. Because it changes the shape of the haircut and the end of the haircut itself.

Therefore, the skin master adjusts these parameters exactly to suit himself and the precision of the work. It is necessary to add that the hack is a universal tool.

They need to work manually in the middle of the trench, getting under the lower grates, and standing in the pit. The most important thing is to accurately follow the knitting patterns. The self-propelled tool is made from thin reinforcement, which collapses in lamellas. Using a handle, twist a plastic hose or tube and heat it up after inserting the rod.

After drying, the plastic envelops the haircut, which simmers nicely on the corrugated surface of the gusset. Just recently the handles were prepared from the tree, the masters wrapped the haircut with duct tape. Vyazhatsya dart reinforcement shears for the additional gachka way wrapping the rest. At this end, it is wrapped up in a special scheme, which will be discussed below.

Addition of inertial action

All the same hook, except for the soft end, we insert into a special handle. It has a threaded screw thread, and a spring is rotated in the middle, which indicates that the latch is rotated at the release position.

At the end of the day they boil, they need to pull the device from the place of connection. The haircut begins to wrap itself in spiral grooves, wrapping itself around its axis. This is how twisting occurs.

In essence, this is what a tool with a cartridge does. For example, a screwdriver. Then the latch can be inserted into the screwdriver chuck and turn on the remaining one. Obertalny Rukh create a twisted dart. This method is often used by fakists.

Pistol

This device falls into the category of special tools, which is only suitable for one task. In the design of this power tool, insert sockets with a dart (the smell is changeable).

That’s why the device itself is working, and he himself is behind the singing scheme. Handy, quick, clear, but expensive, worth the price of a gun.

The only downside is that it requires electricity either for direct connection or for charging batteries.

Methods and schemes

It’s not easy to assemble a frame for a foundation by hand, at first glance. On the right is the labor that takes time. Apart from all these schemes, there are complex options. Axis is one of them.

1. From the shattered bay, the piece is cut to a length of 25-30 cm.
2. The wine is forming in vain.
3. Wrap two strings around the place.
4. The loop is clapping like a cackle, and it needs to be turned.
5. With twisting, after two turns, one end of the dart is reached.
6. After another two turns, another.
7. External twisting is carried out.

The tool for tying the reinforcement according to this pattern - the hook - must wrap itself until the docks are tied with the dart and do not become too tight. However, it is not easy to twist, the material itself becomes weaker.

In addition, one loop can be twisted in other patterns. This is the simplest option. In addition, the installation of the gages makes it possible to develop folding schemes, which are most often encountered in the great assembly industry. For a private house-building, there are simple knitting options. Of course, it will be simpler if you make ready-made cuts from two loops at the ends. Simply wrap it around the place, two loops are pulled onto the hook, which begins to wrap.

Options for different foundations

The easiest way is to knit a reinforced frame. In essence, the result is from the later and transverse cuts, which stand between them and are considered important. Most often, the center is 20 x 20 or 30 x 30 cm. For such a design, vikorist is knitted with one loop.

The same can be said about the frame for, because its design is a series of gratings connected by transverse short rods. However, there is one subtle point in the weaving of the reinforcement of a stitch foundation - the tightness of the structure. Here it is important to evenly distribute the connection points throughout the entire length of the bent and cut rods that create the reinforcement frame.

Video about how to quickly learn to knit.

The technology for strengthening the frame structure is in no way different from the stitch technology. Here are the same diagrams and methods of linking the structure with reinforcement. If the frame is damaged, then it is necessary to ensure that the frame itself in these sporuds is a vertical structure with vertically installed main rods, which are connected to each other by rods of smaller diameter.

This frame is made up of straight-cut girder. Therefore, the same knitting is carried out here, as in slab or stitch bases. If the crossbar is round, then the later rods are one shear, bent into a circle. This is tied to the vertical elements in the singing places of the frame with the order of installation.

Visnovok

The process of reinforcement of the foundation is associated with a number of operations that contribute to the final result. And here the binding of the reinforcement plays an important role. The main methods are connected with awkward circuits, most often single-loop. Because of this process, you could get into trouble if you were a human being. I just need an hour and a bit of rest.
