CONNECTING DEVICE FOR BRIDGE

PROBLEM TO BE SOLVED: To follow even large deformation in the bridge shaft direction by fixing a plate-like upper constitutive body, which is arranged so as to cover a clearance part generated between adjacent beams or the beams and the ground from above, to the beams or one side of the ground, and supporting it so as to be freely displaceable in the bridge shaft direction from the beams or the other side of the ground. SOLUTION: An upper constitutive body 18 whose upper surface 18a is formed as a part of a bridge surface 17, is installed so as to cover a clearance part 16 from above, and an end part 18b on the pavement slab 13 side is fixed to a pavement slab 13, and an end part 18c on the connecting plate 15 side is supported by a connecting plate 15 so as to be freely displaceable in the A direction. On an under surface 18d, a downward projecting wall part 26 is arranged in a condition of being fitted to an upward projecting wall part 29. A lower constitutive body 20 is also arranged so that a bar-shaped part 30 turns to the pavement slab 13 side. Thereby, even when a bridge or the ground is displaced in the bridge shaft direction, continuity of a bridge surface is kept, and a device having a large allowable deformation quantity can be realized.
