Reinforcement of the foundation with their own hands - an event aimed at strengthening the basis and an increase in the construction period. Concrete copes with loads, but without amplification is unable to resist his bending, so you need to build a reinforcement framework.

How to reinforce the foundation? In order for the design to cope with all statistical loads, it should be correctly calculated, and then installed for all mounting rules. Below will be considered how to properly reinforce the ribbon foundation, as well as the reinforcement of the foundation, the calculation of the reinforcement, laying and bidding.

Choose a high-quality material that dozens of years can serve

When laying a frame, the following rules of the ribbon foundation should be observed:

• when selecting products, it is recommended to use the material and 400 material and above;
• you should not connect the rod with welding, the cross section will be weakened;
• the design is required to be enhanced in the corners and in non-standard planes;
• should not apply a sleek type of wire;
• framework in the ribbon foundation must be laid in the tape, the minimum step from the edge should be at least 50 mm, and the metal will not be exposed to rust;
• the rods with each other need to be adopted with overlay, the step is selected based on the diameter of the wire, in practice it is held at least 25 cm;
• when filling the formwork, the solution should be monitored so that the stones are not stuck in the frame nodes.

If the formwork frame has been erected by all technologies, it means that the basis will cope with all the loads, but if there are no cracks, chips will appear in the future.

Selection of material

Horizontal reinforcement is located along the perimeter of the foundation

With the erection of the reinforcing framework for the foundation, it is necessary to use three different types of wires.

Each of them is used for major groups:

• horizontal, is located along the perimeter of the formwork;
• connecting cross;
• connecting vertical.

The last two types, many experts are called "clamps", since their main task is to fasten all the design nodes. Before choosing fittings for the ground, it is required to carry out strength calculations.

Vertical fittings

Proper reinforcement of the foundation of a single-storey private house or garage can be made independently without the help of specialists.

Since the load on the base will act small, then the calculation on bending and the compression is not required, it is necessary to use the rods with a diameter of 12-14 mm.

To create a skeleton, the foundation under the house is elevated, given the following:

• when selecting horizontal rods are guided by the rule - the cross section should be 0.1% of the length of the tape; If the base ribbon is up to 3 meters, then the minimum diameter should be taken 10 mm if the length is greater than the standard value, the wire must be thicker than 12 mm, and it is impossible to use the reinforcement with a cross section of more than 40 mm;
• the connecting crossing is selected as follows - the wire diameter should be equal to or greater than ¼ thickness of the horizontal bar; The thickness of 6-8 mm is standard;
• the connecting vertical wire is used depending on the height of the tape, the products with a diameter of 6-8 mm are suitable for finely brewed bases.

The rules of reinforcement of the bubble foundation of a bellped type provide for the use of rods from 8 mm and more.

Bits

All parts of the valve must be interconnected with a wire

In the reinforcement of various types of foundations, the most reliable method can be considered the connection of all parts using a wire, such a skeleton has increased strength, unlike the same, but when welding.

The combination of knitting and welding of nodes is practiced, only rectilinear areas are allowed to weld among themselves, angles, complex bends required to fasten only wire.

How to make reinforcement? Apply the following methods for mating:

• knitting machine (pistol);
• hook.

The last method is successful for small volumes, since the montage of the frame will take a lot of time.

When viscating crochet, use a special annealed wire with a cross section of 0.8-1.2 mm.

Ribbon base frame circuit

To build a reliable base for the house should not be saved on materials, as in the future it will turn into serious problems. How to secure the rods in the angles of formwork? In practice, two main types of angular compounds are used: on the plot of tapes and between adjacent vertical areas.

Different types of carcasses
At the corners of the foundation, the reinforcement must be bent under 90 degrees

Each reinforced method implies the use of certain technologies. For corners, ribbons are used:

• rigid paw; When installing on the edge of each reinforcement, it is raised at the right angle "paw", the wire becomes similar to the poker, the bend length is selected from the accounting of the rod cross section, equal to 35 diameters; The bend is connected to the corresponding perpendicular area so that the outer rods of one tape be fastened with the same other, internal;
• clamps "Molds G"; The method of a bundle is the same as the last case, the difference is only that instead of the paw of a M-shaped wire length of each side equal to 50 diameters of the valve; The rods are fixed between themselves so that the external rods of one tape are fastened with the internal other, it will be more reliable;

• clamps "Form P"; When the angles are connected, two clamps will be required, the length of each side is also equal to at least 50 wire diameters, the blank is welding with two reinforcing rods located in one plane and reinforcement, located at an angle of 90 degrees.

How is the connection of the expanded base angles?

The external reinforcement should be unhappy before you need an angle indicator, then an additional rod is fixed to it, to give greater strength.

It is important to remember that the external elements are bonded with internal.

In reinforcement, it is necessary to pay attention to the distance from the reinforcement to the surface. In this case, metal elements can not be put right on the bottom of the trench of the foundation. The minimum distance from the ground to the rod should be at least 8 cm.

Crochet

Crochet gun

Such a reinforcement technique of foundation implies the use of specialized tools. To this end, you can purchase a crochet gun. However, this is an expensive construction tool that is beneficial with permanent work on the execution of orders, but it is impractical to buy it for one-time use.

Therefore, during the reinforcement, the usual mating hook is most often used. Before use, it is recommended to first make a template - a special workbench that serves to relieve and accelerate work. For its manufacture, bars are taken from a tree with a width of up to 0.5 m, and up to 3 m long. If the step is to do more, the template will be cumbersome and uncomfortable in use.

In the tile foundation, the reinforcement knit a grid, whose rod is perpendicular to

In a wooden frame, holes are made by a drill and grooves, on the outlines repeating the rods themselves. Next, they are sliced \u200b\u200bin size slices. The length of the knitting wire is recommended about 0.2 m. Now you can fix the reinforced bars.

When crocheted crochet, two types of technology are usually found. With a slab foundation, most often resorted to knitting of the reinforcement, located perpendicular to one another. This method is called transverse reinforcement. Reinforcement of the belt foundation with its own hands means a convenient way to mating to connect the reinforcement of the Vangest.

How to reinforce the ribbon foundation with your own hands? In the reinforcement procedure, it is necessary to comply with the following technology for the formation of a single frame. It is necessary to start working from the folding of the wire in half and fix it in the place of the alleged compound. At the same time, the location of the connections is made with the same step along the entire length of the joint in several different places.

The knitting wire must be in the recess of the reinforcement profile. So, in the place of the required connection, make a folded wire with a hook loop. Now you need to start turning the knitted wire with rotating tool, then carefully remove the hook. For details on the reinforcement of the slaughter foundation, see this video:

At each site of bonding, the brass should be repeated the procedure described above 4-5 times, since the clutch only in one place may entail the shift of the rod of the entire frame. Unlike perpendicular compound with a one-time method of mating, the design may be unreliable and cracks and defects will go in the future.
