PROBLEM TO BE SOLVED: To provide a bridge girder support device with a simple structure, which can be manufactured smaller at fully low cost with less working man-hours. SOLUTION: Between a bridge column 1 and a bridge girder, a support body 3, which includes a highly rigid lower shoe 5, a sequentially-laminated elastic body 7 arranged on the lower shoe 5, and a highly rigid upper shoe 6, is disposed. The lower shoe 5 is fixed to the side of the bridge column 1, and the upper shoe 6 is fixed to the side of the bridge girder. The weight of the bridge girder is elastically supported by compression deformation of the elastic body 7. Around the support body 3, a highly rigid cylindrical body 8 having a height from the lower shoe 5 to the upper shoe 6 is disposed. COPYRIGHT: (C)2011,JPO&INPIT |
