Plastically deformable support bodies (16) are embedded in a gel-like elastic body (15). A bottom-surface adhesive layer (15b) of the gel-like elastic body (15) is bonded to a floor surface (F), and a pressurizing plate (13) is kept on a top-surface adhesive layer (15a). A leg section (2) of equipment (1) is restrained from moving laterally with a bolt (22) provided on the pressurizing plate (13). A load of the equipment (1) is used to apply pressure to a vibration-damping pad (12) via the pressurizing plate (13). A restraint wall (18) is disposed around the vibration-damping pad (12) and a caulking compound (20) is packed in the opening between the pressurizing plate (13) and the floor surface (F). The caulking compound (20) is blocked by the restraint wall (18), and the gel-like elastic body (15) is allowed to deform due to a gap (19) formed between the restraint wall (18) and the vibration-damping pad (12). According to the present invention, a simple and hygienic seismic isolation structure can be used to prevent vibration, noise, and toppling of equipment installed on a floor surface without using anchor bolts. |
