COMPOSITE GIRDER USED STEEL-CONCRETE OF CONTINUOUS OF PRESTRESS BRIDGE AND IT'S BUILDING METHOD

摘要

A steel-concrete composite girder on continuously point one prestressed composite girder bridge and its construction method is arranged to effectively renitency, works to the boundary of steel-concrete composite girder. A steel-concrete composite girder on continuously one prestressed composite girder bridge of point includes a H-shaped steel truss (10), a concrete component (20), a support unit (30) and a coupling member (40). H-shaped steel truss is mounted in the continuous point in the bridge mark of composite girder bridge. Concrete component is fixed to the lower part of purlin. Concrete component is arranged on continuous point. Support unit is fixed to every one end and the lower part of purlin of concrete component. Support unit controls every one end of concrete component. Support unit renitency is performed.
