ERECTION METHOD AND ERECTION STRUCTURE OF BRIDGE

PROBLEM TO BE SOLVED: To provide an erection method and an erection structure of a bridge, eliminating a setting beam and effectively using the upside of a girder to improve workability and decrease the possibility of precipitation and drop. SOLUTION: In this erection method of a bridge, a new girder 3 is hoisted and connected to an existing girder 2 on a bridge pier or an abutment 1 to erect the bridge. A stepwise or slope face temporary receiving part 4 is formed on the axial end of the existing girder 2 to descend from the top face toward the chip, and an engagement part 5 shaped corresponding to the temporary receiving part 4 is formed at the axial end of the new girder 3. The new girder 3 is hoisted to engage the engagement part 5 of the new girder with the temporary receiving part 4 of the existing girder 2 to enter the temporary receiving state, and in this temporary state, the temporary receiving part 4 and the engagement part 5 are connected to each other.
