(54) FOUNDATION

The invention relates to the construction and construction of foundations for columns of industrial, civil and agricultural buildings. The known foundation includes adjacent spatial blocks, each of which is made of vertical and inclined elements symmetrically arranged for it 1. The closest in technical essence to the proposed foundation is a foundation that includes volumetric blocks composed of flat trusses, a support plate having square in terms of openings, on which the blocks rest, adjoining each other and forming in the place of adjoining the glasses under the columns 2. The disadvantage of the known foundations is their lack On the rationality of static work. The purpose of the invention is to improve the static operation of the foundation. The goal is achieved by the fact that in the foundation, which includes a base plate and mounted on it three-dimensional blocks made of flat trusses, adjacent to each other and forming glasses under the columns at the location, the base plate is solid, and three-dimensional blocks are made in the plan in the form of pr angular equilateral triangles adjacent to each other along the entire contour, with flat trusses in each volumetric block vertically mounted and interconnected by connections, and glasses under the columns are formed in the place of adjoining verschin acute-angled blocks. FIG. 1 depicts the foundation plan; in fig. 2 shows section A-A in FIG. one; in fig. 3 - volumetric block, general view; in fig. 4 — node I in FIG. one; in fig. 5 — node II in FIG. 1. The foundation includes volumetric blocks 1 installed on the base plate 2. The volumetric block 1 is made of flat vertically mounted trusses 3 and has a rectangular equilateral triangle shape in plan. Flat trusses consist of upper ca 4, lower ca 5, diagonals 6 and racks 7, with the extreme stands with cut 8. Flat trusses 3 are connected

between each connection 9. Staples 10 are mounted on the block on the right angle cut.

Volumetric blocks 1 adjoin each other along the entire contour, while in the place of adjoining the right angles of the bracket 10 are connected with brackets 11 anchored in the slab, and in the place of adjoining the acute angles there are glasses 12 under the columns 13. Joints between blocks 1 and the joints between the pillars 13 and the blocks 1, they are monolithic concrete.

The proposed foundation in terms of static work is more rational, since the work included the entire supporting section, on which the columns are installed, which improves the static operation of the structure.

The proposed foundation provides an increase in the carrying capacity and an improvement in static work, as a result of which it is possible to transfer significant loads on the column and the base to be burned and the material consumption of the foundation to be reduced.
