GIRDER FOR RAHMEN STRUCTURE, THE MAKING METHOD AND BRIDGE CONSTRUCTION METHOD USING GIRDER FOR RAHMEN STRUCTURE

摘要

PURPOSE: A girder for a rahmen bridge, a manufacturing method thereof, and a bridge construction method using the same are provided to cost-efficiently construct a bridge by optimizing several devices required for reinforcing a corner part. CONSTITUTION: A girder for a rahmen bridge comprises two lower vertical support beams(110), an upper horizontal support beam(120), and end inclination tension devices. The lower vertical support beams are extended from the top of a bridge lower structure. Hinge bearings(140) are installed on the top of the lower vertical support beams. The upper horizontal support beam is placed on the top of the hinge bearings. The end inclination tension devices comprise tendons(130). The tendons are inclinedly installed between the lower vertical support beams.
