PILLAR STRUCTURE Russian patent published in 2019 - IPC E01F9/631 E02D27/42 E04H12/08 

FIELD: construction.

SUBSTANCE: invention relates to the pillar structure. Pillar structure comprises a pillar with a tubular outer sheet metal wall; foundation with a cavity for receiving the lower portion of the outer wall of the pillar; wedge element for fixing the pillar in said cavity by means of jamming; and a reinforcing element attached to a portion of the portion of the outer wall of the pillar placed in the cavity to counteract the collapse of the portion. Mentioned wedge element fits tightly to the outer wall of the pillar by means of supporting protrusions, while providing free space between the supporting protrusions to allow parts of the outer wall of the pillar to be pressed into some of these data spaces, when said outer wall is collapsed due to a collision. Reinforcing element is located at the axial distance from the upper opening of the cavity to allow, in connection with the collision with the pillar, the crushing of the part of the external wall of the pillar located between the reinforcing element and the opening of the cavity.

EFFECT: technical result is prevention of separation of the pillar from the foundation.
