STEEL-CONCRETE COMPOSITE GIRDER AND STRUCTURE USING THE SAME

摘要

PURPOSE: A steel-concrete composite girder and a structure using the same are provided to lower the cost by pouring concrete without using a form and reduce the relative size of a steel-concrete composite girder. CONSTITUTION: A steel-concrete composite girder(1000) comprises a steel girder(100), a cross member(200), and a bottom plate(300). The cross member is joined to the top of the steel girder by crossing the steel girder. The bottom plate is joined to the cross member and is equipped with a reinforcement part(310) in the same direction as the steel girder. The top of the bottom plate is arranged by a lattice member and a Π-shaped channel to reinforce transversely. The steel-concrete composite girder is joined to a girder connection part through a bottom plate connection part, placed on a bridge post, and concrete is poured on the top.
