REINFORCED BEAM WITH VERTICAL H-STEEL OR I-STEEL FOR STIFFNESS, THE CONSTRUCTION STRUCTURE AND BRIDGE CONSTRUCTION METHOD USING THE SAME

摘要

A reinforced beam with a vertical h-steel or i-steel for stiffness is provided to facilitate interconnection of a horizontal beam and a beam and economically manufacture and construct the beam by using a shaped steel. An installation structure using a reinforced beam comprises a lower structure of a bridge, and a beam(100) installed at the lower structure and reinforced using a vertical reinforcement member(200). A horizontal beam(300) is connected to the vertical reinforcement member(200) and has an I-shaped or H-shaped section. An upper plate is provided on the beam(100). An L-shaped lower connection plate(510) is installed at the vertical reinforcement member(200). A lower flange(230) is fixed to the upper surface of the L-shaped lower connection plate(510). An L-shaped upper angle(520) is installed at the inner side surface of two flange of the vertical reinforcement member(200).
