次に上記構成とした防振、免震材の作動状態について説
明する。Next, the operating state of the vibration isolation and seismic isolation material configured as described above will be explained.
先ず、列車、大型車両等の通過による振動が生じると、
地盤（Ａ）に固定されている下側の剛性部材（２）が振
動するが、この振動の大部分が弾性部材（３）によって
吸収されるため、上側の剛性部材（１）にはほとんど伝
達されない。このため、建造物（Ｂ）自体の振動は非常
に小さいものとなる。First, when vibrations occur due to passing trains, large vehicles, etc.
The lower rigid member (2) fixed to the ground (A) vibrates, but most of this vibration is absorbed by the elastic member (3), so almost no vibration is transmitted to the upper rigid member (1). Not done. Therefore, the vibration of the building (B) itself becomes extremely small.
次に、地震が発生して地盤（Ａ）に垂直方向の強度の震
動が生じると、弾性部材（３）に埋設されているコイル
バネ（４）の垂直方向の復元力により、弾性部材（３）
が垂直方向に伸縮自在となり、低い剛性を有することと
なるので、垂直方向の震動を吸収し減衰させるように働
く。Next, when an earthquake occurs and strong vibrations occur in the vertical direction in the ground (A), the vertical restoring force of the coil spring (4) embedded in the elastic member (3) causes the elastic member (3) to
Since it is vertically expandable and has low rigidity, it works to absorb and attenuate vibrations in the vertical direction.
さらに、コイルバネ（４）の水平方向の復元力の作用に
より、弾性部材（３）が水平方向の震動をも吸収して減
衰させるように働く。Further, due to the horizontal restoring force of the coil spring (4), the elastic member (3) acts to absorb and attenuate horizontal vibrations as well.

この発明は上述のような構成を有するものであり、従っ
て、弾性部材（３）が垂直方向に伸縮自在となるように
、弾性部材（３）にコイルバネ（４）が埋設されている
ので、コイルバネ（４）の垂直方向の復元力によって、
弾性部材（３）の剛性が低くなり、地震等による垂直方
向の強度の震動を吸収することができる。This invention has the above-mentioned configuration, and therefore, the coil spring (4) is embedded in the elastic member (3) so that the elastic member (3) can expand and contract in the vertical direction. Due to the vertical restoring force in (4),
The rigidity of the elastic member (3) is reduced, and strong vibrations in the vertical direction due to earthquakes or the like can be absorbed.
さらに、コイルバネ（４）の水平方向の復元力が作用し
て、水平方向の震動をも吸収することができる。Furthermore, the horizontal restoring force of the coil spring (4) acts to absorb horizontal vibrations as well.
