SEISMIC ISOLATION DEVICE AND LAMINATION LAYER RUBBER SUPPORTING DEFORMATION AMOUNT ADJUSTING METHOD
PROBLEM TO BE SOLVED: To provide a seismic isolation device and lamination layer rubber supporting deformation amount adjusting method capable of preventing buckling at the lamination rubber supporting and capable of adjusting an amount of sinking.SOLUTION: This invention relates to a seismic isolation device present between an upper structure and a lower structure. The isolation device comprises a damper mechanism having a sliding part pushed by a flexing member for applying a press contacting force to one of the upper structure and the lower structure to absorb vibration energy while sliding between it and one of the structures; and a sinking restriction mechanism for restricting the sinking by a supporting part for supporting the upper structure while the other of the upper structure and the lower structure being abutted through a sinking of prescribed amount of the upper structure associated with a relative displacement between the upper structure and the lower structure in a horizontal direction. A clearance is provided of enabling a spacer for adjusting the amount of sinking to be placed between the supporting part and the other.SELECTED DRAWING: Figure 2
【課題】積層ゴム支承の座屈を防止するとともに沈み込みの量を調整することが可能な免振装置及び積層ゴム支承の変形量調整方法を提供する。【解決手段】上構造物と下構造物との間に介装される免振装置であって、前記上構造物及び前記下構造物のうちの一方への圧接力を付与する撓み部材に押圧されて前記一方との間で摺動して振動エネルギーを吸収する摺動部を備えたダンパー機構と、水平方向における前記上構造物と前記下構造物との相対変位に伴う前記上構造物の所定量の沈み込みにより、前記上構造物及び前記下構造物のうちの他方が当接されて前記上構造物を支持する支持部を備え、前記沈み込みを規制する沈み込み規制機構と、を有し、前記支持部と前記他方との間に前記沈み込みの量を調整するスペーサーが介装可能な空隙が設けられている。【選択図】図２
