Claims (1)

[Claims for Utility Model Registration] (1) A seismic isolation support unit disposed between a structure and a support that supports the structure, the seismic isolation support unit being spaced apart in the horizontal direction. at least three or more multi-stage elastic supports disposed in a row, each multi-stage elastic support being formed by stacking at least two or more elastic supports in the vertical direction, forming each multi-stage elastic support In the seismic isolation support unit, where the upper and lower connecting parts of the elastic supports are connected by a common connecting plate, the structure side 1. A seismic isolation support unit characterized by comprising an energy absorber that is installed vertically between the base and the support side and exhibits a damping function against horizontal movement. (2) The seismic isolation support unit includes an upper mounting plate that is attached to the structure side and a lower mounting plate that is attached to the support body side, and the energy absorber is inserted and fitted into each hole of the upper mounting plate and the connecting plate. 2. The seismic isolation device according to claim 1, wherein the upper mounting plate and the connecting plate are respectively coupled to each other, and the lower mounting plate and the energy absorber are coupled by a mounting means that prevents horizontal movement of the lower end of the energy absorber. support unit. (3) An auxiliary multi-stage elastic support is provided at the center of all the multi-stage elastic supports constituting the seismic isolation support unit, and the auxiliary multi-stage elastic support has at least two elastic supports. Claim 1, wherein the bodies are stacked vertically, the upper and lower connecting portions of the stacked elastic supports are connected to the connecting plate, and the energy absorbers are vertically installed inside each of the elastic supports. The seismic isolation support unit described. (4) At the center of all the multi-stage elastic supports constituting the seismic isolation support unit, there is a single type elastic support that extends between the structure side and the support side and whose intermediate part is connected to the connecting plate. 2. The seismic isolation support unit according to claim 1, wherein an elastic support is provided, and the energy absorber is vertically arranged inside the single elastic support. (5) The seismic isolation support unit includes an upper mounting plate that is attached to the structure side and a lower mounting plate that is attached to the supporting body side, and the single elastic support body is inserted through each hole in the upper mounting plate and the connecting plate. The upper mounting plate and the connecting plate are connected to each other by fitting, and the lower mounting plate and the single elastic support are connected by a mounting means that prevents horizontal movement of the lower end of the single elastic support. 5. The seismic isolation support unit according to claim 4.
