PROBLEM TO BE SOLVED: To provide a floor slab structure capable of making a crack hard to be caused by upward provided pavement, in the floor slab structure of not connecting a joint part in the bridge axial direction of a floor slab panel adjacent in the bridge axial direction.SOLUTION: In a floor slab structure 1, sandwich lightweight floor slab panels 10A and 10B are laid in the bridge axial direction, and have a horizontal-shaped bottom steel plate 10a on the lower side, and have vertical reinforcement plates 10b and 10c extending in the vertical direction in both end parts in the bridge axial direction of the bottom steel plate 10a, ans have lightweight concrete 11 placed in a steel shell. A joint part 10X in the bridge axial direction is not connected. A first projection part 10h projecting in the bridge axial direction is provided on one side vertical reinforcement plate 10b among two vertical reinforcement plates 10b and 10c opposed in the joint part 10X in the bridge axial direction, and a first recessed part 10g recessed in the bridge axial direction is provided on the other side vertical reinforcement plate 10c. The first projection part 10h and the first recessed part 10g are fitted in a state of interposing a first cushioning material 10j composed of resin between mutual ones.SELECTED DRAWING: Figure 8 |
