FIELD: construction.
SUBSTANCE: support stand is made in the form of a tubular structure, walls of which are reinforced with longitudinal stressed and unstressed rod reinforcement and transverse spiral reinforcement, including an end-thrust bearing and an embedded item at least on one end of the stand, at the same time the embedded item comprises a shell in the form of a ring from steel strip, a mounting ring fixed on the inner surface of the shell, and anchor reinforcement from separate rods, which are made with inclined section of rod bending in the lower part, changing into the straight end, parallel to its upper part, and installed so that the section of the upper part of the rod changing into bend; covers the mounting ring, and the specified straight end is fixed to the shell under the mounting ring. Rods of anchor reinforcement may be fixed with non-stressed rods of longitudinal reinforcement of the stand wall. Anchoring reinforcement may also be made of separate U-shaped rods.
EFFECT: increased bearing capacity and reliability of stand support.
