Sliding seismic isolation device
Provided is a high-performance sliding seismic isolation device with a slider that realizes a contact pressure of 60 MPa. The device includes an upper shoe 1 and a lower shoe (2) having sliding surfaces 1a and 2a with curvatures, respectively; and a columnar steel slider (7) disposed between the upper shoe (1) and the lower shoe (2), the slider having an upper surface 4a and a lower surface 4b that are in contact with the upper and lower shoes, respectively, and have curvatures. The upper surface 4a and the lower surface 4b of the slider (7) have double-woven fabric layers (5) and (6), respectively, each 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 the sides of the sliding surfaces 1a and 2a of the upper shoe (1) and the lower shoe (2).
