(54) THE FOUNDATION OF THE BUILDING. CONSTRUCTIONS

I

The invention relates to the field of construction, namely to the structures of the foundations of buildings, structures of the spacer tin.

The foundation of the building, the structure, is known, including a reinforced concrete slab laid on the base, on which a vertical supporting element 1 is installed and rigidly fixed.

The disadvantage of the known foundation is a small bearing capacity and high consumption of materials.

The closest technical solution to the invention is the foundation of the building, the structure including a reinforced concrete slab laid on the foundation, on which a triangular vertical support element with a through hole 2 is mounted and rigidly fixed.

The disadvantage of this foundation is a small bearing capacity.

The purpose of the described invention is to increase the bearing capacity of the foundation.

The goal is achieved due to the fact that in the well-known foundation of the building.

facilities, including y.1 and 11 th and :; the base is a reinforced concrete slab, on which a triangular vertical support element with a through hole m is installed and rigidly fixed, a triangular BCpTHKa.ibniiiii, a curved element made of 11p mo 141 with a hypotenuse directed along the lines. raim; - acting forces, acting; their on the foundation; one leg placed on a reinforced concrete slab, and the other - fitted to the building structure, the leg placed on the slab is provided with protrusions, and through holes are formed in the slab in which the protrusions are placed. At the same time, the reinforced concrete slab, in the place of supporting the hypotenuse of the vertical support element, can be fulfilled with

5, an inclined section located perpendicular to the hypotenuse and in the plan can be in the form of an isosceles trapezium with a minor base facing the building; FIG. 1 shows a vertical section of the foundation; in fig. 2 - view A-. in fig. one; in fig. 3 - view B-BN of FIG. 1: in FIG. 4 is a vertical section of a part of the foundation with a slab, made

with a sloping plot; in fig. 5 is a plan of the foundation with a plate having the shape of an isosceles trapezium.

The foundation building includes a reinforced concrete slab 2 laid on the base 1, on which a triangular vertical support element 3 with a through hole is installed and rigidly fixed. At the same time, the triangular vertical support element 3 is rectangular with hypotenuse 4, directed along the resultant 5 forces acting on the foundation; one leg 6, placed on a reinforced concrete slab 2, and the other 7 - facing the building structure (not shown), and the leg 6, placed on the slab 2, is provided with protrusions 8, and through holes 2 are formed in the slab 2, in which protrusions 8 are placed. Reinforced concrete plate 2 in the place of bearing 10 on it of hypotenuse 4 of vertical support element 3 can be made with an inclined section I, placed perpendicular to hypotenuse 4, and in plan can be in the form of an equilateral trapezium 12 with a smaller base 13 facing in buildings, facilities. In the upper part of the vertical support element 3, a nest 4 is formed for the stand 15 of the building spacer system, structure, as well as the support platform 16 for installation of the foundation beams 17. A stiffening diaphragm 18 can be provided in each longitudinal row of foundations.

The principle of operation of the foundation of the building, the structure is as follows.

From the resultant 5 forces acting on the foundation, hypotenuse 4 of the vertical support element 3 works for central compression, which allows maximum use of its bearing capacity. The leg 6, placed on the plate 2 and rigidly attached to it with the help of the projections 8 placed in the through holes 9, works together with the plate 2 for bending. The inclined section 11 of plate 2 prevents the foundation from shifting under the action of thrust. The trapezoidal shape of the plate 12 2 allows the stress to equalize to the base 1. The use of the building foundation, the structure allows to increase the carrying capacity.
