ELASTIC SUPPORT FOR BRIDGE

PROBLEM TO BE SOLVED: To provide an elastic support for a bridge which can elastically support a bridge girder in perpendicular and horizontal directions to a support body, while causing no tensile deformation to an elastic member even when the bridge girder is inclined in an axial direction of the bridge in relation to the support body by a live load. SOLUTION: A lower end side plate 54 of the elastic member 50 is fixed to a lower shoe 40, and upper end side plates 51, 52, 53 are formed to be able to come into contact with an upper shoe 30 from below. A horizontal movement of the upper end side plates 51, 52, 53 in relation to the upper shoe 30 is restricted by bolts 51b, 52b, 53b, respectively, whereby the bridge girder 1 can be elastically supported to a bridge pier 2. Since the second upper end side plate 52 and the third upper end part side plate 53 are movable downward in relation to the upper shoe 30, an upward force is not applied to the second upper end side plate 52 even when an end side of the upper shoe 30 in the axial direction X of the bridge is moved upward by the live load.
