摘要： A seismic isolation bearing device is disclosed in which a laminated elastic rubber-steel bearing adapted to isolate horizontal seismic loading cooperates with a vertical isolation device employing a compression spring, or equivalent device, effective for isolating vertical seismic loadings whereby a three dimensional seismic isolation device is effective to isolate both vertical and horizontal seismic loadings to insure the structural integrity of a superstructure against damage induced by seismic events. The isolation device formed of an isolation cylinder fixed to the structure, with an upper fixing plate vertically movable within the cylinder. A plurality of steel balls being disposed within a space formed between the perimeter of the upper fixing plate and the interior wall of the isolation cylinder. The balls facilitating the guided relative vertical movement between the upper fixing plate and the isolation cylinder. A compression spring within the cylinder and between the upper fixing plate and the structure serves to dampen the vertically imposed seismic loads.
