（産業上の利用分野）
この発明は減衰性能を持つ免震装置に関するものである
。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) This invention relates to a seismic isolation device with damping performance.

絶縁型免震構法における免震装置には安全性の面から地
震時の水平力を減衰させる機能を有することが要求され
、これを反映して現在さまざまな手法によりエネルギー
吸収能力を持たせた免震装置が開発されつつある。(Problem to be solved by the invention) Seismic isolation devices in insulated type seismic isolation construction methods are required to have the function of attenuating horizontal force during earthquakes from the viewpoint of safety. Seismic isolation devices with energy absorption ability are being developed using techniques.

。One end of the plurality of dampers faces each other, and both ends are connected to an end plate and a steel plate so that the dampers can be tilted in any direction. When the seismic isolation device is deformed in a certain direction, the damper on the side in that direction is compressed, and the damper on the opposite side is pulled, so that a damping force is applied to the seismic isolation device.
（実施例） 以下本発明を一実施例を示す図面に基づいて説明する。(Example) The present invention will be explained below based on the drawings showing one embodiment.
この発明の免震装置Ａは積層ゴム１の中央に円筒形の中
空部ａを設け、ここへ複数のダンパ２を立設してなるも
のである。The seismic isolation device A of the present invention is constructed by providing a cylindrical hollow part a in the center of a laminated rubber 1, and having a plurality of dampers 2 erected therein.
中空部ａは第２図のように上下に鋼板６で水平に仕切ら
れ、仕切られた各中空部ａ、ａに複数のダンパ２を、一
端を対向させ、他端を開き、両端をエンドプレート４と
鋼板３とに接続する。The hollow part a is horizontally partitioned vertically by steel plates 6 as shown in FIG. 4 and the steel plate 3.
接続はダンパ２が免震装置Ａの変形に従って任意の方向
へも傾斜可能に、自在なものとし、各ダンパ２は傾斜し
た状態で立設される。The connection is such that the damper 2 can be tilted in any direction according to the deformation of the seismic isolation device A, and each damper 2 is installed upright in an inclined state.
図示した実施例では一中空部ａに３本のダンパ２を用い
た場合を示すが、免震装置Ａの減衰力に方向性を持たせ
ないためにも少なくとも６本のダンパ２を必要とし、こ
のとき上部の中空部ａではダンパ２が鼎立した状態とな
り、下部では鋼板３に関して対称に配置される。In the illustrated embodiment, three dampers 2 are used in one hollow part a, but in order to prevent the damping force of the seismic isolation device A from having directionality, at least six dampers 2 are required. At this time, the damper 2 is in an upright state in the upper hollow part a, and is arranged symmetrically with respect to the steel plate 3 in the lower part.

左側のダンパ２は圧縮を、中央と右側のダンパ２，２は
引張を受け、上下針６本のダンパ２による減衰力が免震
装置Ａに与えられる。In Fig. 2, when a horizontal force is applied to the seismic isolation device A and it deforms to the left as shown in Fig. 13, the upper hollow part a,
The damper 2 on the left side receives compression, and the dampers 2, 2 on the center and right sides receive tension, and the damping force by the damper 2 with the six upper and lower needles is applied to the seismic isolation device A.
この鼎立したダンパ２は上下方向の振動減衰にも有効に
機能する。This upright damper 2 also effectively functions to damp vibrations in the vertical direction.
（発明の効果）
この発明は以上の通りであり、免震装置は積層ゴム内に
上下に設けた多数のダンパにより効果的に減衰力を得る
ことができる。(Effects of the Invention) The present invention is as described above, and the seismic isolation device can effectively obtain damping force using a large number of dampers provided above and below within the laminated rubber.
またこの装置は既成のダンパを積層ゴム内に組み込めば
よいので、そのためのスペースを特別に設ける必要がな
い。Furthermore, since this device can incorporate a ready-made damper into the laminated rubber, there is no need to provide a special space for it.
