BASE ISOLATION DEVICE AND BASE ISOLATION STRUCTURE PROVIDED WITH THE SAME
To provide a simple base isolation device capable of preventing buckling when undergoing large deformation and to provide a base isolation structure provided with the base isolation device.SOLUTION: A base isolation device 10 comprises a multi-stage laminated rubber bearing 18 made up of: laminated rubber 22 which is installed in a base isolation layer 16 between a superstructure 12 and a substructure 14 and arranged in stages in a vertical direction; and a connection member 32 which is arranged between upper and lower laminated rubber 22 and connects the upper and lower laminated rubber 22. The base isolation device also has a buckling prevention bearing 20 which is installed at a distance from the multi-stage laminated rubber bearing 18 in a horizontal direction. The buckling prevention bearing 20 has a slide section 36 which allows the connection member 32 to come into contact with and to slide on the same when the multi-stage laminated rubber bearing 18 undergoes deformation of predetermined magnitude or more.SELECTED DRAWING: Figure 1
【課題】大変形時の座屈を防止することができる簡易な免震装置およびこれを備えた免震構造物を提供する。【解決手段】上部構造物１２と下部構造物１４との間の免震層１６に設けられ、上下方向に多段に配置した積層ゴム２２と、上下の前記積層ゴム２２の間に配置され、上下の前記積層ゴム２２を連結する連結部材３２からなる多段積層ゴム支承１８を備える免震装置１０であって、前記多段積層ゴム支承１８から水平方向に離れた位置に設けられた座屈防止支承２０をさらに備え、前記座屈防止支承２０には、前記多段積層ゴム支承１８が所定の大きさ以上に変形した際に前記連結部材３２が接触して滑動可能な滑り部３６が設けられているようにする。【選択図】図１
