The main task of the Foundation is to transfer the burden of the building (structure) to the ground. Obviously, the concrete will undergo internal pressure in the foundation - the walls are pressed from the top, and the floor is crushed from the bottom. Concrete, in contrast to reinforcement, compression works very well. So, why is the reinforcement used in the cassette foundation?
The technology of the reinforcement tape is the foundation
Strengthening the tape foundation is a key factor in its reliability and durability (you can separately learn about strengthening the foundations for pilots). In accordance with the provisions of SNiP no. 2.03.01-84, it is not allowed to use uncomplicated reasons in residential construction.
Location and calculation of the reinforcement in the ribbons
The tape has the foundation of non-standard geometry: ten times longer than the depth and width. Due to this form, almost all loads are distributed along the belt. Concrete stone itself can not replace these loads: its bending strength is not enough. In order to build with increased strength, not only concrete is used, but reinforced concrete is a concrete stone with steel elements inside - steel reinforcement. The process of laying metal is called reinforcement of the base strips. It's easy to do with your own hands, the calculation is basic, the schemes are known.
Rules for reinforcement
During operation, the substrate is exposed to various loads from the weight of the house, from soil movement and from freezing. By pressing the house, the lower part encounters the voltage, and the upper part is pressed. Frosting forces, whose lifting force can exceed the weight of the house, and cause stretching in the upper part of the strap, should also be considered. Improper cassette reinforcement can cause destruction and consequently destruction of walls and the entire building. Therefore, the reinforcement of the strips should be based very seriously, the foundation is the foundation of the entire building. In this article we will present detailed drawings and reinforcement schemes for the foundation of the strips.
How is the reinforcement placed in the strips?
Armature angle elements: 1. Horizontal reinforcement. 2. Overlap. 3. Vertical reinforcement. 4. Transverse reinforcement. 5, additional transverse reinforcement. 6. The L-shaped clamp
