DEVICE TO STRENGTHEN VAULTED FLOOR OF A BUILDING UNDER RECONSTRUCTION Russian patent published in 1995 - IPC

FIELD: civil engineering. SUBSTANCE: strengthening the floor of a building with carrying beams rested on walls, and self-carrying and carrying vaults is made using reinforced concrete strengthening elements. The elements are positioned on both sides of beam and connected to it by rests, installed on lower face of bea. Working reinforcement of the reinforced concrete element is prestressed in the form of tie rods, attached to ends at outer surfaces of walls so to adjust stress value. Holes for rod-type anchors provided with stressing devices and catches are made in the body of vault. In so doing, working reinforcement is connected through sliding links either to rod-type anchors or to rests and anchors. EFFECT: strengthening floor rigidity when asymmetric operating loads effect. 5 dwg
