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

摘要

A steel-concrete composite girder on the continuous point of a prestressed composite girder bridge and a construction method thereof are provided to resist efficiently the stress acting on the junction of the steel-concrete composite girder. A steel-concrete composite girder on the continuous point of a prestressed composite girder bridge comprises a H-steel girder(10), a concrete member(20), a support unit(30) and a coupling member(40). The H-steel girder is installed on the continuous point positioned in the bridge post of the composite girder bridge. The concrete member is fixed to the lower part of the girder. The concrete member is arranged on the continuous point. The support unit is fixed to each end of the concrete member and lower part of the girder. The support unit controls each end of the concrete member. The support unit resists the stress acting.
