The foundation of the house is the support and the basis of the entire future structure. The whole structure depends on how correctly it is erected, all further work. The key to the reliability of the foundation will be a reinforced concrete frame. This design consists of steel reinforcement, which is poured with concrete. Reinforcement is able to strengthen the design of the foundation, protect against loads. Carrying out the reinforcement of the foundation will be able to prevent the appearance of cracks, the occurrence of other damage in the area of stretching.
What should be used for the foundation?
It is best to use structures made of hot -rolled round steel. Such reinforcement can be several varieties:
• Smooth,
• with a periodic profile.
If with the first variety more and more – less clear, then the second raises some questions. This article will clarify them.
Reinforcement with periodic profiles – rods that have corrugations of a special shape. They are protrusions located at an angle to the axis. Such a corrugation can provide a more strong, better adhesion with concrete, which is important not only for high -rise buildings in Moscow, but also for country houses, for example, in Nizhny Novgorod.
From below and from above, reinforce the foundation with reinforcement, the section of which is 10 – 12 mm. Calculation of real loads on the foundation is carried out, after which the reinforcement is selected with the desired section.
How to install reinforcement correctly?
Mount the designs in accordance with the specifics provided for in the work project. This project should reflect the installation sequence. Everything must be done in such a way that the elements laid out previously could not complicate the installation of subsequent. All designs created using reinforcement should be located inside the foundation at a distance of at least 5 cm from the outer surfaces.
The rods of the reinforcement must be driven around the entire perimeter of the trench into the bottom. Such methods are built a vertical basis for a reinforced frame. All rods must be driven into two rows. Horizontal rods are necessarily attached to a vertical basis, transverse.
You need to think about installing the reinforcement so that a metal high -quality frame of rods appears inside the foundation, a step in which is 30 cm. A particularly important point will be the method of fastening metal rods among themselves.
Another popular type of construction rental is a profile pipe. You can buy a profile pipe today in special construction stores and in wholesale warehouses in all major cities of the country.
