PSC GIRDER CONNECTION STRUCTURE WITH STRENGTH CONNECTOR DETAIL FOR SUBSTITUTION OF REBAR PLACEMENT IN DECK AND BRIDGE CONSTRUCTION METHOD USING THE SAME

摘要

PURPOSE: A cross-shaped PSC girder connecting structure with a horizontal reinforcement connecting material and a bridge construction method using the same are provided to be economically feasible by maximizing the strain efficiency of the PS tendon of a PSC girder. CONSTITUTION: A cross-shaped PSC girder connecting structure comprises a PSC girder(100) and a horizontal reinforcement connecting material(300). An upper flange(130) of the PSC girder is horizontally extended and is adjacent to the side of an extended upper flange of the PSC girder. A board-shape synthesis steel material(200) upwardly projected from the inside is embedded on both upper sides of the expanded upper flanges. A horizontal connection hole(210) is formed in the projected synthesis steel material.
