Supporting device for bridging material in bridge spacing

摘要

PROBLEM TO BE SOLVED: To always position an erection material in the center in the width direction of an expansion spacing, regardless of the occurrence of relative displacement in the bridge axial direction between upper structures, when supporting the erection material for supporting a filler for blocking up, for example, a void of the expansion spacing by the upper structure, by being installed in the expansion spacing formed between the upper structures adjacent in the bridge axial direction or between the upper structure and a lower structure.SOLUTION: A support device 1 is constituted of fixing members 2 and 2 fixed to a surface of turning in the erection direction of an erection material 5 such as the adjacent respective upper structures 7 and 7, a receiving member 3 relatively movably arranged in the bridge axial direction to both fixing members 2 and 2 while contacting with both fixing members 2 and 2 by straddling between both fixing members 2 and 2 and receiving the erection material 5 in a state of locking to the erection side of the erection material 5 on both fixing members 2 and 2 and energizing members 4 and 4 for sharing compressive force between the receiving member 3 and the respective fixing members 2, between the receiving member 3 and the respective fixing members 2, arranged in a state of exhibiting restoring force and pressing the receiving member 3, and keeps the restoring force of both energizing members 4 and 4 on both sides of the receiving member 3 in an equal state.
