PROBLEM TO BE SOLVED: To provide a laminate rubber body including lead plug capable of keeping appropriately attenuation function even if it is applied to a super high rise building and the like.SOLUTION: This invention relates to a laminate rubber body 6 including: a laminate rubber part having a rubber layer 2 and a reinforcing plate 3 alternatively laminated to each other in a vertical direction; an open hole 6a passing through the laminate rubber part in a vertical direction; a column-like lead plug 9 filled and sealed in the open hole; and heat absorbing means (coil) 12 for absorbing heat generated by the lead plug. Increasing in temperature of the lead plug is prevented by the heat absorbing means to prevent a shearing stress of the lead plug from being reduced and keeps appropriately the attenuation function. The heat absorption means can be made as a solid body having a higher specific calorific capacity than that of lead and filled in the lead plug. The heat absorbing means can be formed into a coil-like shape or a rod-like shape and it can be formed by at least more than one type of materials selected from steel, copper and aluminum.SELECTED DRAWING: Figure 1
【課題】超高層建築物等に適用しても減衰機能を適正に維持することが可能な鉛プラグ入り積層ゴム体を提供する。【解決手段】ゴム層２と補強板３とを鉛直方向に交互に積層した積層ゴム部と、積層ゴム部を鉛直方向に貫通する貫通孔６ａと、貫通孔に封入された円柱状の鉛プラグ９と、鉛プラグが発する熱を吸収する吸熱手段（コイル）１２とを備える鉛プラグ入り積層ゴム体６。吸熱手段によって鉛プラグの昇温を防止することで鉛プラグのせん断応力の低下を防止し、減衰機能を適正に維持する。吸熱手段を鉛よりも比熱容量の大きい固体とし、鉛プラグ内に封入することができる。吸熱手段をコイル状、棒状とすることができ、鋼、銅及びアルミニウムから選択される少なくとも一以上の材料で形成することができる。【選択図】図１
