DEVICE FOR REINFORCEMENT OF SUPPORTING ASSEMBLY OF BAY CONSTRUCTIONS Russian patent published in 1999 - IPC

Abstract RU 2140510 C1

FIELD: construction, applicable in repair and restoration of bay constructions. SUBSTANCE: the device consists of short double-cantilever purlins, tension bar between the purlins and a cross-arm; the purlins are mounted on the upper face of the supporting construction with employment of a levelling blanket of concrete or mortar with a thickness of not less than the required gap between the bracing cantilevers of the purlins and cross-arms, the purlins and cross-arms in the working condition are arranged at the same level in the plane of their engagement, the purlins and cross-arms are made of rolled stock, for example, of angle; a tension bar is provided for reduction of the anchoring area of the bay construction reinforcement by purlins; the purlin cantilevers and cross-arms get engaged by twisting the fastening nuts on coupling bolts with tension, thus the reinforcement device gets actuated. EFFECT: enhanced operating reliability, durability, fire-resistance of damaged constructions. 12 cl, 19 dwg
