FLOOR SLAB FOR BRIDGE, AND BRIDGE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a bridge structure capable of restraining a floor slab for a bridge from being damaged in its vicinity of the end of a main girder. SOLUTION: A cutout part 42 cut out along a bridge width direction Y is formed at the lower portion of a floor slab body 40A. First reinforcements 44 are linearly disposed at the upper part of the floor slab 40 to straddle the cutout part 42 along a bridge axis direction X. Second reinforcements 46, 48 are disposed on both sides in the bridge axis direction X with the cutout part 42 placed in between. The second reinforcements 46 are disposed on the bridge section A side, and the second reinforcements 48 are disposed on the earthwork section B side. The second reinforcement 46 is composed of an upper part 46A disposed at the same height and in the same direction as the first reinforcement 44; a bent part 46B disposed along the cutout part 42 on the bridge section A side rather than a support position P; and a lower part 46C disposed at the lower part of the floor slab body 40A.
