PSC GIRDER WITH SHEAR BLOCK, PSC GIRDER MAKING METHOD WITH SHEAR BLOCK AND BRIDGE CONSTRUCTION METHOD USING PSC GIRDER WITH SHEAR BLOCK

摘要

PURPOSE: A PSC(PreStressed Concrete) girder forming a shear block on the upper surface, a construction method thereof, and a bridge construction method using the PSC girder forming the shear block on the upper surface are provided to improve a shear composite effect by forming the shear block between shear forming bodies in order to concentrate stress to a part in which a shear force is largely generated. CONSTITUTION: A manufacturing method of a PSC girder(100) forming a shear block on the upper surface comprises as follows. A bottom plate lower longitudinal reinforcing bar(160) is installed on the upper part of a reinforcing bar assembly unit. The bottom plate lower longitudinal reinforcing bar is inserted into a horizontal hole of a shear forming body in order to be separated. The shear forming body is removed in order to complete the PSC girder, and a plurality of shear blocks(150) is separated and is formed on the upper part of an upper flange(110) in the PSC girder. A vertical shear connection reinforcing bar(180) is formed in the reinforcing bar assembly unit, and the reinforcing bar assembly unit penetrates a vertical hole of the shear forming body.
