PROBLEM TO BE SOLVED: To provide a measuring jig which: is used for measuring bolt installation positions in construction work to fix a member to a plurality of bolts protruded from a wall surface; and can improve work efficiency by shortening a construction period.SOLUTION: In a repair method of a bridge 100 which has a bridge pier or a bridge abutment made of concrete, a bridge girder is supported by a steel support member 200 installed on the bridge pier or the bridge abutment through a plurality of anchor bolts 150 fixed thereto. The repair method enables positions of the anchor bolts 150 to be accurately measured in a short period of time by measuring the positions of measurement jigs 10 attached to tips of the anchor bolts 150. Also, because the measurement jigs 10 are vertically attached to the anchor bolts 150, the repair method enables axial directions of the anchor bolts 150 to be measured.SELECTED DRAWING: Figure 1 |
