LEAD-PLUG INCORPORATED LAMINATE RUBBER TYPE BASE INSULATION BEARING
PROBLEM TO BE SOLVED: To provide a lead-plug incorporated laminate rubber type base insulation bearing having a durability improved by preventing the occurrences of cracks or ruptures due to the vibrations of minute amplitudes.SOLUTION: A lead-plug incorporated laminate rubber type base insulating bearing 10 includes: an elastic body 2 having elastic material layers and rigid material layers laminated alternately; and a columnar lead plug 1. The lead plug 1 is arranged in a cylindrical hollow part formed vertically in the elastic body 2, and the lead plug 1 is formed in at least its side face with a film part 11, to which a lubricant is applied.
【課題】微少振幅の振動に起因する亀裂や破断が発生することを防止して耐久性を向上させた鉛プラグ入り積層ゴム型免震支承を提供すること。【解決手段】鉛プラグ入り積層ゴム型免震支承１０を、複数の弾性材料層と剛性材料層とが交互に積層されてなる弾性体２と、柱状の鉛プラグ１と、を備え、鉛プラグ１は、弾性体２の内部に鉛直方向に形成された筒状の中空部内に配置されていて、鉛プラグ１の側面の少なくとも一部には、潤滑剤が塗布されてなる被膜部１１が形成されている鉛プラグ入り積層ゴム型免震支承１０とした。【選択図】図２
