LAMINATION RUBBER BEARING
To provide a lamination rubber bearing of which configuration is simple and less-expensive and capable of realizing a long cycle formation of an object to be mounted through low rigidity in view of its horizontal rigidity while holding a stable supporting function against a vertical load.SOLUTION: This invention relates to a lamination rubber bearing 1 arranged between an upper structure and a lower structure to be mounted, including: a cylindrical lamination body 5 in which several rubber layers 9 and several rigid layers 10 are alternatively laminated in a vertical direction and at the same time having upper and lower openings 5a, 5b released upward and downward, respectively; an upper tight closing 6 and a lower tight closing plate 7 in which each the upper and lower openings 5a, 5b of the lamination body 5 is tightly closed and a liquid-tight fluid chamber 8 is defined inside the lamination body 5, and being connected to each of the upper structure and the lower structure: and predetermined low viscosity fluid F filled in the fluid chamber 8 and sealed.SELECTED DRAWING: Figure 2
【課題】構成が単純で安価であるとともに、鉛直荷重に対する安定した支持機能を保持しながら、水平剛性の低剛性化によって設置対象の長周期化を実現することができる積層ゴム支承を提供する。【解決手段】本発明は、設置対象の上部構造と下部構造の間に設けられる積層ゴム支承１であり、複数のゴム層９及び複数の剛性層１０が上下方向に交互に積層されるとともに、上方及び下方にそれぞれ開放する上下の開口５ａ、５ｂを有する筒状の積層体５と、積層体５の上下の開口５ａ、５ｂをそれぞれ密閉し、積層体５の内部に液密の流体室８を画成するとともに、上部構造及び下部構造にそれぞれ連結された上密閉板６及び下密閉板７と、流体室８に満たされ、封入された所定の低粘度流体Ｆと、を備える。【選択図】図２
