PSC GIRDER HAVING IMPROVED STRONG COUPLING PERFORMANCE OF CORNER PORTION AND CONSTRUCTION METHOD FOR RAHMEN OR BOX TYPE STRUCTURE USING SAME

摘要

The present invention relates to a PSC girder having an improved strong coupling performance of a corner portion and a construction method for a rahmen or a box type structure using the same, which effectively transmits more of a compressive force and a tensile force generated on both ends of the PSC girder placed on a corner portion to concrete the corner portion by constructing the PSC girder and the concrete in the corner portion to strongly be coupled to a bridge pier and an abutment which are a lower structure of a bridge. The PSC girder comprises: a loop-type corner portion reinforcing bar having an upper flange, an abdominal flange, and a lower flange formed to horizontally protrude on an end surface portion of the PSC girder; and a middle corner reinforcing bar portion formed to horizontally protrude from the inside of the PSC girder in a position spaced from an end surface position of the PSC girder to a middle portion of the PSC girder.;COPYRIGHT KIPO 2015
