ANCHOR DEVICE OF PRESTRESSING SYSTEM OF BUNDLES FROM PRESTRESSED REINFORCEMENT OF BUILDING STRUCTURES Russian patent published in 2024 - IPC E04C5/08 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely, to pre-stressing systems of bundles from prestressed reinforcement bars of building structures. Anchor device of the prestressing system of bundles from prestressed reinforcement includes bundles of reinforcing ropes located in the duct tube, the ends of which are placed in the cavity of the support shell and fixed in the anchor cage, a device for injecting the duct tube with a cement mortar, a spiral of indirect reinforcement of concrete of an anchor zone placed on a shell, an injection cover with a branch pipe. On the outer surface of the support shell there are guides parallel to its longitudinal axis contacting the inner surface of the spiral of indirect reinforcement of concrete of the anchor zone, inside it there are inclined slots located equidistantly relative to its axis for arrangement of bundles of reinforcing ropes.

EFFECT: improving the quality of the constructed structure while reducing labour intensity, the cost of its production, and increasing its reliability and durability.
