BASE ISOLATION SUPPORT DEVICE
PROBLEM TO BE SOLVED: To provide a base isolation support device capable of obtaining a stable base isolation characteristic, capable of avoiding fatigue and damage of an elastic layer of a laminate and a vibration damper, and excellent in durability, base isolation effect and manufacturability.SOLUTION: A base isolation support device 1 includes: a laminate 7 having a plurality of annular elastic layers 2 and rigid layers 3 laminated alternately; an upper plate 10 and a lower plate 11 respectively attached to an upper end surface 8 and a lower end surface 9 of the laminate 7; and a lead plug 18 defined by an inner peripheral surface 12 of the laminate 7, a lower surface 13 of the upper plate 10 and an upper surface 14 of the lower plate 11, and arranged at a hollow part 17, the hollow part surrounded by the elastic layer 2, the rigid layer 3, the upper plate 10 and the lower plate 11, and extending in a lamination direction V.SELECTED DRAWING: Figure 1
【課題】より安定な免震特性を得ることができ、加えて積層体の弾性層及び振動減衰体の疲労、損壊を回避することができ、耐久性及び免震効果並びに製造性により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、交互に積層された複数の円環状の弾性層２及び剛性層３を有する積層体７と、積層体７の上端面８及び下端面９に取付けられた上板１０及び下板１１と、積層体７の内周面１２、上板１０の下面１３及び下板１１の上面１４で規定されていると共に弾性層２及び剛性層３並びに上板１０及び下板１１で取り囲まれて積層方向Ｖに伸びた中空部１７に配置された鉛プラグ１８とを具備している。【選択図】図１
