(54) FOUNDATION UNDER THE COLUMN

I

The invention relates to a builder, a structure, in particular to the construction of foundations for industrial and agricultural buildings.

Shell foundations are known, consisting of a support shell, the cavity of which is filled with bulk material l.

The closest technical solution to the invention is the foundation of a pod column comprising a spherical memphane connected to the outer and inner rings and filled with a bulk material, radial screws attached to the outer ring at the same ends, a glass with a protrusion on a thin tirtse 2.

However, the carrying capacity of these foundations is limited, and the static scheme of work is not effective enough.

The purpose of the invention is to increase the holding capacity by improving the static operation.

The goal has been reached by informing the fundus under the column, including the outer and inner rings, connecting a spherical membrane with them, a sprinkle of loose material located between the membrane and the ground, radial cables attached at one end to the outer ring, a glass with the protrusion on the bottom end is provided with an additional ring located under the stadan below the outer ring and coaxially inside, with the other ends of the radiator cables attached to the additional ring, the cup is passed through the inner it simply supported on the ring and an additional ring and its projection wound v.polost additional ring.

FIG. 1 shows the foundation for the column, a cross-section; in fig. 2 shows a section in FIG. one.

The foundation for the column includes outer 1 and inner 2 rings, spherical Memphana 3 connected to them, 4 bulk material filling located between Memphana 3 and soil 5, radial cables 6 attached at the ends to the outer ring 1, cup 7 with a ledge 8 on the bottom the end face, an additional ring 9, a glass 7 is passed through the inner ring 2 and supported on an additional ring 9, and its ledge 8 is inserted into the cavity 10 of the ring 9. A column 11 is inserted into the glass 7, and the gap between the column 11 and the walls of the glass is filled with concrete 12 ,

The assembly of the structural elements of the foundation is carried out using a lifting mechanism, and a bulk material, such as sand or slag, is pumped into the cavity between the soil 5 and the spherical membrane 3. The column 11 transfers the loads to the cup 7. From the cup, the loads are transferred to the additional ring 9, the cables 6 are reinforced with the reinforcing ring 1, and the bulk material to the spherical membrane 3,

The described foundation for the column ensures rational operation of the spherical membrane,

As a result, a significant reduction in the material and metal consumption of the foundation for the column is achieved. (concrete up to 80% and steel up to 30% compared with; with a stepped foundation
