SPRING TYPE VIBRATION CONTROL DAMPER
To provide a spring type vibration control damper capable of preventing excessive deformation of a laminated rubber base isolation device at the time of a huge earthquake and preventing damage of the laminated rubber by imparting a quick deformation restoring function.SOLUTION: A spring type vibration control damper 11 comprises: a cylinder 18 mounted between an upper structure and a foundation structure of a base isolation building structure having a base isolation device interposed between the upper structure and the foundation structure and provided with end plates 23, 24 at both ends; a rod 22 mounted with a piston 21 at the tip; and a coil spring 19 housed in the cylinder 18. The piston 21 is housed in the cylinder 18, one end of the coil spring 19 is fixed to the end plate 23 of the cylinder 18, the other end is fixed to the piston 21, and relative displacement between the upper structure and the foundation structure due to an earthquake is returned to an original position by compression of the coil spring 19.SELECTED DRAWING: Figure 3
【課題】巨大地震時に積層ゴム免震装置の過大変形を防止すると共に、速やかな変形復元機能を付与して積層ゴムの損傷を防ぐことができるバネ式制震ダンパーを提供する。【解決手段】バネ式制震ダンパー１１は、上部構造と基礎構造との間に、免震装置を介在させてある免震建物構造の上部構造と基礎構造との間に取り付けられ、両端に端板２３、２４が設けられたシリンダ１８と、先端にピストン２１が取り付けられたロッド２２と、シリンダ１８内に収納されるコイルバネ１９とからなり、ピストン２１がシリンダ１８内に収納され、コイルバネ１９の一端がシリンダ１８の端板２３に固定され、他端がピストン２１に固定され、上部構造と基礎構造との地震による相対変位に対してコイルバネ１９の圧縮によって相対変位を元の位置に戻す構成とする。【選択図】図３
