摘要

PROBLEM TO BE SOLVED: To provide a bridge girder installation method for providing girders at the upper sections of bridge piers to form a bridge, a girder pull-up crane used for the method, temporary girders, a girder transport vehicle, and girders in a construction field.;SOLUTION: A plurality of girders are provided with temporary girders, and the girder pull-up crane is provided by the guide of the temporary girders. After the girder transport vehicle is prepared for load dispersion, primary girders are transported to the girder transport vehicle and pulled up. After pulling out the girder transport vehicle to provide primary temporary girders, the primary girders are anchored. A method that can apply an assembly method by precast, and an apparatus used for the method can thereby be provided even in the case of a general road bridge.;COPYRIGHT: (C)2009,JPO&INPIT
