The present invention relates to a method for the continuous construction of PSC composite girders using cross beams as fixing parts. In this method, a crossbeam and a reinforcing bar projecting from a side surface at the end part of a girder are integrally joined so converting the crossbeam which is a secondary member into primary member, and continuation prestressing strands are fixed to the crossbeam thereby allowing continuation by introducing secondary prestressing, in a simple fashion, in bridges having a plurality of spans, which is to say two or more spans. The present invention also relates to a structure for the method. |
