Sliding seismic isolation device
A sliding seismic isolation device includes an upper shoe and a lower shoe, the upper and lower shoes having sliding surfaces, and the sliding surfaces having curvatures; and a columnar steel slider disposed between the upper and lower shoes, the slider having an upper surface and a lower surface that are in contact with the upper and lower shoes, respectively, and have curvatures. A double-woven fabric layer is attached to each of the upper and lower surfaces of the slider via an adhesive layer, the double-woven fabric layer containing PTFE fibers and fibers with higher tensile strength than that of the PTFE fibers, and the PTFE fibers being arranged on sides of the sliding surfaces of the upper and lower shoes. A fluorine coat layer is disposed on a surface of the double-woven fabric layer, and a lubricating oil layer is disposed on a surface of the fluorine coat layer.
