COMPOSITE GIRDER BRIDGE CONSTRUCTION METHOD USING TEMPORARY STEEL LATERAL RIB AND PERMANENT CONCRETE LATERAL RIB

摘要

PURPOSE: A construction method of a composite girder bridge using a provisional steel horizontal rib and a permanent concrete horizontal rib is provided to facilitate construction and working and reduce construction costs of a composite girder bridge. CONSTITUTION: A construction method of a composite girder bridge using a provisional steel horizontal rib and a permanent concrete horizontal rib comprises following steps. A composite girder(100) is placed on the top of a bridge post(210). The composite girder is made of two steel girders(110). A steel horizontal composite plate is installed in the composite girder. A temporary steel horizontal reinforcement rib is installed in the steel horizontal composite plate. A permanent concrete horizontal rib(160) is formed on the steel horizontal composite plate. The temporary steel horizontal reinforcement rib is removed from the steel horizontal composite plate. The steel girder, the steel horizontal composite plate, and the permanent concrete horizontal rib are integrated with each other. The slab is formed on the top of the composite girder and the steel plate girder.
