Abstract:
To provide a temporary bridge that can be erected urgently to save lives, transport goods, and the like, in the event of a flood.SOLUTION: Floor slab panels 21, in which multiple pieces are connected in a bridge axis direction so that a connection part can be bent in a direction perpendicular to the bridge axis, are installed on an origin side bank 1 in a spirally wound state. The floor slab panels 21 are sequentially unwound and rotated on a leading girder 5 material previously installed between the origin side bank 1 and an arrival side bank 2, thereby developing and extending a floor slab 20 connected between the origin side bank 1 and the arrival side bank 2. Thus, a temporary bridge 10 is formed in which both ends of the erected floor slab 20 are supported by fulcrum blocks 14, and the floor slab 20 forms an arch shape due to tension introduced into a closing cable 12 stretched below the floor slab 20.SELECTED DRAWING: Figure 1
