PURPOSE: An elastic support for a bridge is provided to easily remove a wedge support member from an upper plate or a lower plate or install the wedge support member on the upper plate and the lower plate by installing the wedge supporting member and an anchor member by a bolt with a dual structure. CONSTITUTION: An elastic support for a bridge comprises a top plate(30A), a bottom plate(30B), and an elastic rubber pad. The elastic support comprises a top and a bottom wedge(50A). The top plate is coupled on a deck structure of a bridge with an anchor member(20). The bottom plate is coupled on a pier structure with the anchor member. The elastic rubber pad is arranged between the top and the bottom plate. The wedge is installed on a side facing the top and the bottom plate. The wedge limits the horizontal movement of the top and the bottom plate. The wedge absorbs impact due to horizontal movement of the top and the bottom plate in case of impact such as earthquake. |
