CONCRETE GIRDER FOR UPPER STRUCTURE OF BRIDGE

摘要

PURPOSE: A concrete girder for the upper structure of a bridge is provided to facilitate the tensile reinforcement of a concrete member and to prevent the rigidity degradation of a post tensile reinforcing material due to corrosion. CONSTITUTION: A concrete girder (11) for the upper structure of a bridge comprises a concrete member and a post tensile reinforcing anchor (30) embedded into the concrete member. The post tensile reinforcing anchor includes an anchor plate, a bolt fastening column, and an anchor bolt. The bolt fastening column is formed on the bottom of the anchor plate and is formed with bolt grooves in the longitudinal direction. The anchor bolt is joined to the bolt fastening column to be screwed to a bolt groove. The anchor bolt is embedded into the concrete member with the head exposed to the outer surface of the concrete member.
