SLIDE BEARING SEISMIC-ISOLATED BUILDING AND SEISMIC-ISOLATED BUILDING
To provide a technology capable of adjusting a vertical rigidity of a slide bearing seismic-isolated device at a seismic-isolated building to a specified vertical rigidity.SOLUTION: A slide bearing seismic-isolated device comprises a slide bearing part and a vertical rigidity adjustment part, the vertical rigidity adjustment part has an upper plate part, a lower plate part, a supporting rubber body mounted on the lower plate part and a ring part projected from either one of the upper plate part and the lower plate part to enclose around the supporting rubber body. The ring part has an inner diameter where a side clearance is formed between it and a side surface of the supporting rubber body at a state before a load of a superstructure may act, a side surface of the supporting rubber body under a state in which a load of the superstructure acts to cause it to be shrunk in a vertical direction is abutted against an inner peripheral surface of the ring part to restrict a deformation of the supporting rubber body, and the supporting rubber body may realize the desired vertical rigidity when the deformation is restricted by the ring part.SELECTED DRAWING: Figure 3
【課題】免震建物におけるすべり支承免震装置の鉛直剛性を所期の鉛直剛性に調整可能な技術を提供する。【解決手段】すべり支承免震装置は、すべり支承と鉛直剛性調整部を備え、鉛直剛性調整部は、上側プレート部と、下側プレート部と、下側プレート部上に設置される支持ゴム体と、上側プレート部および下側プレート部の何れか一方から突設され支持ゴム体の周りを囲うリング部を有する。リング部は、上部構造物の荷重が作用する前の状態における支持ゴム体の側面との間に側方クリアランスが形成される内径を有すると共に、上部構造物の荷重が作用して鉛直方向に収縮した状態における支持ゴム体の側面がリング部の内周面に当接することで支持ゴム体の変形を拘束するように形成され、支持ゴム体は、リング部によって変形が拘束された際に所期の鉛直剛性が発揮される。【選択図】図３
