摘要

PROBLEM TO BE SOLVED: To provide a construction method of main bridge structure and a junction structure between a temporary column and a temporary girder for achieving the same using the temporary column as a bridge structure of a main structure to thereby reduce the construction period and the cost.;SOLUTION: Plural temporary columns 4 are disposed at predetermined intervals and temporary girders are disposed being supported by the plural temporary columns 4, and using the temporary columns 4 and the temporary girders, a bridge body 22 of the main structure is built. After removing the temporary girders, the bridge body 22 and the temporary column 4 are connected to each other being interposed by a joint member 25 between the bridge body 22 and the temporary column 4 to build the main bridge structure 1.;COPYRIGHT: (C)2015,JPO&INPIT
