BASE ISOLATION SUPPORT DEVICE
To provide a base isolation support device capable of providing stable vibration isolation characteristics, and preventing fatigue of an elastic layer of a laminate and a vibration damping body, which is excellent especially in durability, a vibration isolation effect and manufacturability.SOLUTION: A base isolation support device 1 includes: a cylindrical laminate 7 having rubber plates 2 and steel plates 3 which are alternately laminated; upper and lower plates 12 and 13; a lead plug 14; a lid member 22 with a semi-concave spherical surface 20 for occluding one end 21 of a hollow part 17, to guide and assist a plastic flow of the lead plug 14 at one end part 18 in a lamination direction A of the hollow part 17; and a lid member 27 with a semi-concave spherical surface 25 for occluding the other end 26 of the hollow part 17, to guide and assist a plastic flow of the lead plug 14 at the other end part 23 in the lamination direction A of the hollow part 17.SELECTED DRAWING: Figure 1
【課題】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、交互に積層されたゴム板２及び鋼板３を有する円筒状の積層体７と、上板１２及び下板１３と、鉛プラグ１４と、中空部１７の積層方向Ａの一端部１８における鉛プラグ１４の塑性流動を案内補助するべく、半凹球面２０を有していると共に中空部１７の一端２１を閉塞する蓋部材２２と、中空部１７の積層方向Ａの他端部２３における鉛プラグ１４の塑性流動を案内補助するべく、半凹球面２５を有していると共に中空部１７の他端２６を閉塞する蓋部材２７とを具備している。【選択図】図１
