RIGID CONNECTING METHOD BETWEEN PRESTRESSED CONCRETE GIRDER AND SUBSTRUCTURE OF BRIDGE

摘要

According to the present invention, a rigid girder is constructed by stiffening a girder to a bridge or bridge, which is a substructure of a bridge, to effectively control the bending moment and shear force generated in a bridge, and thus the structurally advantageous PS girder and bridge substructure As for the method of hardening, the upper flange to be adjacent to each other in the longitudinal and transverse direction on the upper surface of the bridge substructure; An abdomen extending downward on the bottom of the upper flange; And a protruding block in the form of a rectangular block body protruding in the transverse direction on both connecting portions of the upper flange and the upper abdomen. The outer surface of the protruding block is adjacent to each other in the transverse direction through a PSC girder. The front surface of the protruding block adjacent to each other in the direction, and the horizontal beam for the continuous point portion between the protruding blocks in the transverse and longitudinal direction adjacent to the bridge substructure to extend in the longitudinal and transverse directions.
