A support device for a structure is provided to reduce the size of an upper member by installing a primary horizontal elastic body to the outside of a fixing member, to replace a primary horizontal elastic body easily, to reduce the height of an intermediate member by installing a primary horizontal elastic body only, to increase horizontal bearing capacity and restoring force, to compress a horizontal elastic body in the early stage and to support a bridge easily. The support device(200) for a structure comprises: a lower member(210) installed between a support structure(30) and an upper structure by a footing nut(32) and a bolt(212) to support the load of the upper structure and to absorb horizontal force between the support structure and the upper structure, and provided with a pin hole(214); an upper member(220) installed to the base of the upper structure supported by the support structure by welding or using a bolt and a nut, and attached with a stainless steel plate(222); an intermediate member(230) installed on the base of the upper member and attached with a fluorine resin plate(232) to reduce the frictional force with the stainless steel plate and a pin(234) to bear large shear and bending forces; a vertical elastic body(240) installed between the intermediate member and the lower member to support vertical load of the upper structure elastically and provided with a through hole(242) to penetrate the pin; a fixing member(250) installed on the base of the upper member to be projected downward to install a primary horizontal elastic body(280) horizontally; and an elastic unit(300) composed of a primary horizontal elastic body supporter(260) installed on the outside of the fixing member horizontally to support the outside of the primary horizontal elastic body and the side of the fixing member, a shaft member(270) installed horizontally through a primary penetration unit(252) and a secondary penetration unit(264a) to support the primary horizontal support body horizontally and to transfer the horizontal force generated by the intermediate member and the upper member to the primary horizontal elastic body or the restoring force of the primary horizontal elastic body to the intermediate member and the upper member, and a primary horizontal elastic body(280) coupled to the shaft member to obtain high bearing capacity together with a secondary horizontal elastic body. |
