MEANS AND METHOD FOR RESUMING TO HOME POSITION OF BASE ISOLATION STRUCTURE, AND IMPROVED GROUND PROVIDED WITH THE MEANS
PROBLEM TO BE SOLVED: To provide means and a method for resuming to a home position of a base isolation structure, the means and the method capable of being readily installed, removed and maintained and also being cost-effective, along with an improved ground provided with the means.SOLUTION: A plurality of means 20 (20a) for resuming to a home position is installed around a building foundation 8 so as to directly or indirectly connect a ground 1 and the building foundation 8, for resolving a displacement caused by a tensile force or a pressing force generated in the means for resuming to a home position due to the displacement, using one or both of the forces. The means 20 for resuming to a home position may be an elastic material 23 (23a) or an expansion member 23. An annular, rod-form or plate-form rubber material may be used as the elastic material 23, and a gas-filled damper as the expansion member. An extremely-low-hardness rubber should preferably used as the rubber material. Attenuation means 25 for attenuating a vibration or a cushioning material 62 for filling a cushioning clearance 70 may be provided further between the ground 1 and the building foundation 8.
【課題】設置、取り外し、メンテナンスが容易であり、かつコスト的にも有利となる、免震構造の原点復帰手段及び原点復帰方法、ならびに該手段を備えた改良地盤を提供する。【解決手段】原点復帰手段２０（２０ａ）は、地盤１側と建物の基礎８側とを直接もしくは間接につなぐよう建物の基礎８の周囲に複数個配置され、ずれによって前記原点復帰手段２０に生じた引張り力もしくは押圧力のいずれか一方もしくは双方を利用して前記ずれを解消させる。原点復帰手段２０は、弾性材２３（２３ａ）もしくは伸縮部材２３のいずれかとすることができ、弾性材２３としては環状、棒状もしくは板状のゴム材、伸縮部材としてはガス封入ダンパとすることができる。ゴム材としては超低硬質ゴムを利用することが好ましい。地盤１側と建物の基礎８との間にはさらに、振動を減衰させるための減衰手段２５、あるいは緩衝空隙７０を埋める緩衝材６２が配置されてもよい。【選択図】図１
