ANCHORING DEVICE Russian patent published in 2018 - IPC E04C5/12 E01D19/14 

FIELD: construction.

SUBSTANCE: anchoring device consists of reinforcing beams containing twisted wire reinforcing strands and placed, with the exception of the end sections, in lubricant-filled protective shells, and anchors, each of which comprises a base plate, an anchor yoke made with coaxial cylindrical channels and conical recesses, in which wedge clamps are located. The end sections of the reinforcing strands are located in the wedge clamps. Each base plate is made in the form of a disk with cylindrical channels coaxial with the corresponding channels of the anchor yoke, in which the protective shells of the anchor strands are arranged with the possibility of sealing. Sealing is carried out by a lubricant. The end sections of cylindrical channels of the anchor yoke are made with cylindrical bores coaxial with the channels of the base plate, in which the shell ends of the corresponding reinforcing strands are arranged with the possibility to interact with their end part. Each shell end, the ends of the wedge clamps, the cylindrical channel and the end section of the reinforcing strand form an airtight chamber filled with a lubricant. The sections of the reinforcing strands above the wedge clamps are protected with casings and a protective cup.

EFFECT: simplifying and increasing the reliability of corrosion protection, facilitating the repair work of the anchor device, reducing the size and improving the reliability of the base plate.
