ASEISMIC BASE ISOLATION SUPPORT DEVICE
To provide an aseismic base isolation support device capable of attaining a stable aseismic characteristic and additionally showing in particular a superior durability, seismic effect and manufacturability.SOLUTION: An aseismic base isolation support device 1 comprises a disc-like upper plate 2 fixed to a structure of upper part such a building and the like, a disc-like lower plate 3 fixed to a lower part structure such a foundation and the like, several toric rigid layers 4 and elastic layers 5 alternately laminated between the upper plate 2 and the lower plate 3 and concentrically arranged to each other, a centrum 10 defined by a lower surface 6 of the upper plate 2 and an upper surface 7 of the lower plate 3 and each of the inner peripheral surfaces 8 and 9 of the rigid layers 4 and the elastic layers 5, and a laminate body 14 vulcanized and adhered to a cylindrical outer peripheral surface 11 of the rigid layers 4 at the inner peripheral surface and having a cylindrical covering layer 13 integrated with a cylindrical outer peripheral surface 12 of the elastic layers 5, and a lead plug 15 arranged at the centrum 10.SELECTED DRAWING: Figure 1
【課題】安定な免震特性を得ることができ、加えて耐久性及び免震効果並びに製造性に特に優れた免震支持装置を提供すること。【解決手段】免震支持装置１は、建物等の上部の構造物に取付けられる円盤状の上板２及び基礎等の下部の構造物に取付けられる円盤状の下板３、上板２及び下板３間において交互に積層されていると共に互いに同心に配された複数枚の円環状の剛性層４及び弾性層５、上板２の下面６及び下板３の上面７並びに剛性層４及び弾性層５の夫々の内周面８及び９で規定されている中空部１０並びに内周面で剛性層４の円筒状の外周面１１に加硫接着されていると共に弾性層５の円筒状の外周面１２と一体となった筒状の被覆層１３を有した積層体１４と、中空部１０に配された鉛プラグ１５とを具備している。【選択図】図１
