THREE-DIMENSIONAL SEISMIC ISOLATOR
PROBLEM TO BE SOLVED: To provide a three-dimensional seismic isolator that eliminates a risk of a vertical movement seismic isolation unit overturning to enable reduction in the number of seismic isolators.SOLUTION: A three-dimensional seismic isolator has a structure where a horizontal movement seismic isolation unit 10 and a vertical movement seismic isolation unit 12 are connected vertically. The vertical movement seismic isolation unit 12 is composed of two upper and lower cylindrical containers 28, 30 taking a vertical axial line as their common center. Into the inner side of one cylindrical container 30 is fitted relatively slidably in the vertical direction the other cylindrical container 28. At positions having different heights between cylindrical side walls 36, 38 of both containers are provided with two or more O-rings 40. In a tightly closed internal space 44 surrounded by the two cylindrical containers 28, 30 is sealed gas or air.SELECTED DRAWING: Figure 1-1
【課題】上下動免震ユニットの転倒のおそれをなくし、設置数を減らせる三次元免震装置を提供する。【解決手段】水平動免震ユニット１０と上下動免震ユニット１２とを上下に連結した構造を有する三次元免震装置であって、上下動免震ユニット１２は、上下方向の軸線を共通の中心とする上下２つの円筒型容器２８、３０からなり、一方の円筒型容器３０の内側に他方の円筒型容器２８が上下方向に相対的にスライド可能に嵌合しており、双方の円筒状側壁３６、３８の間の高さの異なる位置に２つ以上のオーリング４０が設けられており、２つの円筒型容器２８、３０により囲まれた密閉された内部空間４４にはガスまたはエアーが封入されている。【選択図】図１−１
