SLIDING SEISMIC ISOLATOR AND SEISMIC ISOLATOR SUPPORT
To provide a sliding seismic isolator and a seismic isolator support which are excellent in dust resistance to a sliding surface that constitutes the sliding seismic isolator and which can guarantee the friction coefficient at the time of design.SOLUTION: A sliding seismic isolator 40 has a cradle 43 comprising a spherical seat 44 having a first concave spherical surface 44a, a sliding body 45 having a first convex spherical surface 45b accommodated in the first concave spherical surface 44a and a second convex spherical surface 45a on the opposite side of the first convex spherical surface 45b, and a shoe 41 having a second concave spherical surface 41c on which the second convex spherical surface 45a slides. A dustproof sheet 50 is attached to the shoe 41, and a part of the dustproof sheet 50 extending from the shoe 41 toward the cradle 43 is in contact with the cradle 43.SELECTED DRAWING: Figure 2
【課題】滑り免震装置を構成する滑り面への防塵性に優れ、設計時の摩擦係数を保証することのできる、滑り免震装置と免震支承を提供すること。【解決手段】第一凹球面４４ａを有する球座４４を備えている、受け台４３と、第一凹球面４４ａに収容される第一凸球面４５ｂを備え、第一凸球面４５ｂの反対側に第二凸球面４５ａを備えている摺動体４５と、第二凸球面４５ａが摺動する第二凹球面４１ｃを備えている沓４１とを有する滑り免震装置４０であり、沓４１には防塵シート５０が取り付けられており、沓４１から受け台４３に向かって延設する防塵シート５０の一部が受け台４３に接触している。【選択図】図２
