DEVICE FOR ANCHORING COMPOSITE REINFORCEMENT Russian patent published in 2021 - IPC E04C5/12 

FIELD: construction industry.

SUBSTANCE: invention relates to the field of construction, namely to equipment for the production of pre-stressed building structures. In the device for anchoring composite reinforcement, the body is made telescopic, consisting of separate conical thin-walled rings, inside which a thin-walled truncated conical wedge with a cavity in which longitudinal stiffeners are installed is placed. Longitudinal composite plates are installed in pairs between the inner body of the device and the conical wedge, which are located coaxially to the inner stiffeners of the conical wedge. In the composite mutually touching planes of the plates, longitudinal open grooves are made along the inner faces, and the grooves are arranged mirror-symmetrically along the entire length of the plates and are shaped in the form of an open semicircular groove, or an open rectangular groove for compressing and anchoring the ends of the reinforcement, while a layer of friction material is applied to the inner open grooves of the plates.

EFFECT: increasing in the reliability of anchoring the end sections of the reinforcement bundles and the convenience of fixing them, simplifying the assembly and disassembly of the anchoring device.
