MOVEMENT RESTRICTOR FOR BRIDGE GIRDER HAVING INCREASED INTEGRATION BETWEEN STEEL PIPE AND INTERNAL CONCRETE

摘要

PROBLEM TO BE SOLVED: To provide a movement restrictor for a bridge girder with a square steel stopper increased in rigidity by increasing the integration of internal concrete with a square steel pipe. SOLUTION: In this movement restrictor for a bridge girder having increased integration between the steel pipe and the internal concrete, deformed reinforcements 3 are disposed on the inner peripheral surface of the square steel pipe 2 filled with the internal concrete 1. The square steel pipe 2 has weld parts 4 to which the deformed reinforcements 3 are welded. COPYRIGHT: (C)2009,JPO&INPIT
