Rapid construction method and jig for reinforcement of steel plate reinforced concrete viaduct

摘要

Problem to be solved: to secure and secure the multi-story rigid frame viaduct in a short period of time. Solution: a steel plate s is placed on a support frame 12 which is installed on a beam B between a bridge pier P in the construction to increase the seismic resistance of a pier P by winding a reinforcing steel sheet s in a bridge pier P of an existing multi-layer rigid frame viaduct and increasing the earthquake resistance of a pier A construction jig, which is disposed so as to be freely tilted to the leg P, is installed on the ground g, and after the construction of the construction fixture in which the receiving base 22 is tilted is set on the pair of beams B, after the reinforcing steel plate s is fixed on each of the receiving base 22, the receiving table 22 is fixed After the reinforcing steel sheet s is erected vertically, and the reinforcing steel sheet s is provided on both sides of the outer periphery of the pier P, the reinforcing steel sheet s is welded to the reinforcing steel sheet s, and the mortar m is injected between the reinforcing steel sheet s and the outer peripheral surface of the bridge leg P.
