CONNECTION STRUCTURE BETWEEN GIRDER BRIDGE AND GIRDER BRIDGE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a connection structure between a girder bridge and a girder bridge structure thereof, endurable even against a giant earthquake and a giant Tsunami generated in response to the giant earthquake.SOLUTION: A structure connects a girder bridge 4 installed on a plurality of bridge piers 1 installed in a multispan, and is provided for acquiring two connection structures by a constitution for integrally rigidly connecting a projecting type capital 3 and the girder bridge 4 by imparting prestress by tensionally fixing a PC steel material 8 by connecting the girder bridge 4 installed on both sides of the projecting type capital 3 by the PC steel material 8 penetrating through the projecting type capital 3 by integrally providing the projecting type capital 3 on the bridge pier 1 or by elastically connecting the projecting type capital 3 and the girder bridge 4 without imparting tensioning force to the PC steel material 8 or by the tensioning force up to 0.2 Pu, and the girder bridge structure caused by it becomes the girder bridge strong in strength by constructing the girder bridge structure by combining its two connection structures.
