The foundation of the building is subjected to high loads. In most cases, the strength of the material is concrete, bricks, insufficient to compensate for soil movements or trimmed. To strengthen the base, laying the reinforcement in the ribbon foundation, monolithic and even pile.

Rules and Schemes of Armature

Laying of reinforcement and fastening depend on the design of the foundation. For different bases, the scheme uses different.

Ribbon foundation

By performing the calculation of reinforcement for it and the development of the compound scheme, it is necessary to consider:

  • Frames put on concrete to vertical rods;
  • Straight rods are laid with an overlap at 20-25 cm;
  • Connections with the allen should be separated into the dispersion;
  • The wire section is chosen in the depth of the foundation - not less than 0.1%;
  • The frame does not come into contact with the formwork.

The frame is considered a structural element for the foundation, so the tests under load does not pass. His task: to warn the offset when stretching or bending load, and not increase the carrying capacity.

Features are as follows:

  • The upper and lower belt bind to each other P-shaped steel clamps. Bundles in the ends are excluded;
  • If the slab foundation has a thickness of no more than 15 cm, only 1 grid is allowed;
  • Install the framework necessarily on the sublimaton. Monitors the fittings not in contact with the formwork;
  • Cell side no more than 40 cm.

Put the grid on any designs with resting legs - spiders, frogs, tables. If not ready, such details make it yourself.

Scarlet is a monolithic tape connecting concrete piles of the foundation. By design, it resembles a ribbon foundation, which often leads to errors.

With the reinforcement, the woodworks need to be considered:

  • Scarlet does not give in to collective loads, as separated from the ground. There is only a bending moment on it in areas where the rack is thrown into the beams;
  • Standard framework for woodwork need to strengthen. Near the columns additionally reinforce the upper belt, and the lower - all over;
  • You can use only steel rods for reinforcement.

Concrete pile foundation also needs reinforcement. The framework of the poles is associated with the design in the frame, both with the bottom and the upper belt.

Features of the structure, are as follows:

  • The frame is performed both round and square sections;
  • In each post, at least 4 rods are laid;
  • With the shield formwork it is allowed to take only rectangular clamps;
  • Boot concrete poles are reinforced only at the top.

Stages of fitting stages

The base of the house is usually performed from concrete. This is a durable and reliable material that, nevertheless, is not too resistant to stress on compression and stretching. Improve the strength and mass of the foundation has no washed. It is correct to improve its rigidity, that is, create an additional framework. It is this effect that provides a knitting of reinforcement.

A strengthening is performed in a specific sequence:

  1. First of all, choose the laying scheme. The reinforcement rods and the grid in the end should be in the depths of concrete and cannot be contacted with groundwater. It is necessary to place them as uniformly as possible so that the framework distributes the additional load on the entire foundation.
  2. The design is collected separately. The frame is a series of rectangular frames. Their sizes are such that after installing the circuit turns out to be at a distance of 10 cm from the bottom, the top and the side of the formwork. The number of frames depends on the length of the perimeter. The distance between the contours leaves 50 cm, maybe less.
  3. For the corners of the frame, the longitudinal rods connecting the contour into one integer. The diameter of the bar depends on the magnitude of the intended load. It is possible to fix the rods not only with welding, but also knitted wire.
  4. Reinforcement of angles is performed using a M-shaped iron clamp or adhesion and legs. Fall is at least 60-70 cm.
  5. Before filling the foundation, the frame is lowered into the formwork and recorded: put on the backups of the brick or stone. Stop better segments.

Methods mating fittings

There are several methods of bonding rods and the grid with their own hands:

  • welding frames and rods;
  • navigation;
  • Connection to plastic clamps.

Methods for mating reinforcement are chosen on the basis of the nature of the foundation and their own capabilities. For welding, you need to be able to work with a welding unit, while the wire is a tool available to the beginner builder.

Advantages and disadvantages of welding

Bunch of reinforcement for the foundation of welding - the method is reliable and efficient.

The advantages of his undoubted:

strokes are not inferior to the strength of the rod;

The resulting frame does not have weak links, all ligaments are equally durable;

The method is equally reliable both in the construction of multi-storey buildings and small cottages.

Disadvantages are significant:

To properly connect the framework elements, you need the experience of the welder. Far from everyone owning them;

The method is not suitable if fiberglass fittings are used to enhance;

Welding - the work is dirty, dangerous and takes a lot of time.

This method is usually chosen when they deal with a bulk bulky frame, designed for greater load.

Pros and cons connection by mating method

When constructioning of one-story cottages, the laying and nipping of the valve is more often performed. It takes for this wire of the desired diameter, optionally galvanized, since the entire frame will still be immersed in the thickness of the concrete.

Wire for mating fittings G66623SC

Advantages of this method mass:

To knit reinforcement, do not need a great experience or specific skills;

The work takes up a minimum of time, because, in fact, the builder needs only to tighten the wire 2 of the rod;

Easily eliminate possible shortcomings: wire is unwinding or snacks with nipples;

Stacking and mating can be performed directly in the formwork.

Minuses of the method:

The frame is not too tough. When transferring large segments, the design is often loosened and the attachment is necessary to recyclable;

It is not suitable for enhancing heavy structures designed for high load.

Features of the compound of reinforcement plastic clamps

The easiest foundations are enhanced by thin rods or even a grid. It is more profitable to use plastic clamps. They are simple, easy, ensure reliable fixation. And for their installation, neither effort nor experience is needed.

In fact, there are a lot of flaws in such a way:

  • Plastic is sensitive to low temperatures, in the cold it bursts. Therefore, it is possible to put clamps only in warm weather;
  • If the frames are somewhat and they have large sizes, the clamps will need a lot, which will noticeably increase the cost of reinforcement;
  • It is impossible to move on the finished design, because plastic is not as durable.

Tools for mating fittings, technology work with them

Knit the frame manually is difficult, especially if thick wire is used.

Need a special tool:

  • hook for mating;
  • screwdriver;
  • knitting gun.

Adaptations have their advantages and disadvantages.

How to knit enforce with crochet?

Mating crochet with their own hands are performed in several ways.

To make a simple knot, come so.

  1. The fragment of the wire with a length of 15-10 cm is folded in half, then bend re-, but not the end, manufacturing the semblance of the hook.
  2. Refine crossed rods with a curved end, so that the loop turns out.
  3. Enter a knitted hook in the loop, pick up a free end and put the place of docking again.
  4. The hook stretch over and chew the wire until it breaks.

How to knit enforce with crochet, depends on the nature of the parts connected: beams and columns, rod and clamp. For the latter, a dead node is used.

Make it like this:

  1. The wire with a length of 20-40 cm bends in half, at the end, the loop is performed.
  2. We put the wire under the rod loop forward to the left of the clamp so that 2-4 cm remains.
  3. Spin the fragment on top of the clamp, are again introduced under the rod.
  4. Crochet Through the loop stretch the end of the wire.
  5. The hook is pulled by simultaneously performing several revolutions before the loop beaten.

Using the hook frees from the need to apply large efforts when twisting.

Special gun for knitting

Staying and knitting of reinforcement is faster through a special tool - gun. By sight, he resembles a drill. A knitting wire roll is inserted into the instrument housing. To make a knot, it is enough to send it a "darule" to the place of docking and click on the trigger.

The method has shortcomings. First, it is worth the tool that is not suiced, secondly, the node will not be unleashed. It is necessary to cut the wire.

Using a hook screwdriver

In order not to buy an expensive pistol, but speeding up knitting, cost upgraded by a modernized screwdriver. For this, from a conventional slate nail with a diameter of 5 mm, a hook is made. The device is clamping in the cartridge.

Standard technology: folded 2 times the wire is settled under the reinforcement, the hook captures the loop, and twists it when you press the start button. To tighten the high power node is not needed. Use in this quality the simplest and easy models. When working, expose the minimum speed of revolutions.

Even the simplest foundation must be strengthened. Apply for this carcasters from steel rods and grids. The elements are welded or associated with knitting wire. The choice of the assembly method depends on the size and nature of the foundation.
