(54) FOUNDATION

The invention relates to the construction, in particular to the construction of foundations for columns.

Known foundation for the column, including the base plate and the shell with a glass, supported on the plate 1.

The disadvantages of this foundation are the complexity of manufacturing its elements and the increased consumption of materials. ..V

Closest to the present invention is a foundation comprising a support plate made with peripheral and central protrusions, and a shell having inclined walls connected in the upper part of the upper part and vertical walls forming the cup, supported respectively on the peripheral and central protrusions 2.

The disadvantages of the known foundation are the high labor intensity of the construction, the irrational static work and the lack of a non-destructive ability.

The purpose of the invention is to reduce the complexity of the construction of the foundation and increase its carrying capacity.

The goal is achieved. in that the foundation, which attaches the support plate, made with peripheral and central protrusions, and a shell having inclined walls connected in the upper part and vertical walls forming the cup, supported respectively on the peripheral and central protrusions, are provided with racks installed in the glass, the upper ends of which are combined the horizontal bolt, and the shell is executed on the composite of two rectilinear elements opposite each other, the vertical wall of each of which has an L-shaped outline in plan.

FIG. 1 given the plan of the proposed foundation; in fig. 2 shows a section A-A in FIG. in fig. 3 shows a section BB in FIG. in fig. 4 - prismatic shell, general view;

The foundation consists of a base plate 1 with protrusions protruding upward in the central 2 and peripheral 3 parts, on which two prismatic shells are installed symmetrically

25 4 L-shaped profile with an L-shaped vertical wall 5 in plan, with the number 1 of vertical walls 5 to the central ledge 2 of plate 1 with the formation of glass 6, in the cavity

30 of which are placed racks 7 with a protruding bolt 8 with concrete 9 concrete joints. In the glass of the transom 8, a column 10 is installed, monopolized with concrete 11.

The installation of the proposed foundation is made as follows. Reinforced concrete base plate 1 is installed on the prepared base of the soil or it is made on site from A1OLITHIC reinforced concrete. On the plate 1 is installed using a lifting mechanism e shows the shell 4, having vertical L-shaped walls 5 in plan, which are adjacent to the protrusion of the base plate 1 and to each other with the formation of the cup 6. In the cavity of the cup 6 they install a rack 7 with a protruding crossbar 8 with concrete grouting 9 joints between base plate 1 and shells 4. A column 10 is installed in the transom 8 glass and the grouting of the joints with concrete 11 is established.

The application of the proposed foundation provides a rational static joint operation of the slab with shells in the monolithic glass, which allows reducing the cross section of the foundation structures and simplifying the manufacture of structural elements.
