GIRDER LIFTING ERECTION METHOD AND GIRDER ERECTION JOINT STRUCTURE

PROBLEM TO BE SOLVED: To provide a girder lifting erection method and a girder erection joint structure excelling in working efficiency and safety and contributing to cost reduction without needing temporary materials and attachment of these materials. SOLUTION: In this girder lifting erection method, a hanging implement 2 on a pier top block 2 on a bridge pier 1 or an abutment is hung penetrating the pier top block and locked to a girder on the ground, then the hanging implement is lifted by a hanging implement driver on the pier top block up to the side of the pier top block from the ground, and a joint part at the axial end of the lifted girder is connected to a joint part 10 of the pier top block to fix and erect the girder between the pier top blocks. At this time, both joint parts can also be connected by setting the joint part at the axial end of the girder lifted to the side of the pier top block by lifting the hanging implement by the hanging implement driver, to the underside of the joint part of the pier top block. The girder erection joint structure is an erected structure of the girder on the bridge pier by the girder lifting erection method. COPYRIGHT: (C)2007,JPO&INPIT
