To provide a spring type seismic damper capable of preventing excessive deformation of a laminated rubber seismic device upon a giant earthquake and preventing damage on the laminated rubber designed with a quick deformation restoration function.SOLUTION: A spring type seismic damper 11 according to the present invention is a seismic building structure provided with a seismic isolator arranged between an upper structure and a base structure, and comprises: a cylinder 18 which is attached between the upper structure and the lower structure, and of which both ends are provided with end plates 23, 24; a rod 22 provided with a piston 21 attached on its tip; and a coil spring 19 received in the cylinder 18. The piston 21 is received in the cylinder 18, one end of the coil spring 19 is secured on the end plate 23 of the cylinder 18, the other end is secured on the piston 21, and a relative displacement between the upper structure and the base structure (extension or compression of a relative distance therebetween) by an earthquake is returned to an original position by extension or 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ことを目的とする。【解決手段】本発明に係る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であって、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、前記ピストン２１がシリンダ１８内に収納され、前記コイルバネ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、前記上部構造と基礎構造との地震による相対変位（相対間距離の伸びまたは縮み）に対して前記コイルバネ１９の伸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
