る。In addition, the vibration-isolating floor assembly of the vibration-isolating floor was eliminated, and the pillars were swingably connected to the pedestals attached to the building floor and the free access floor through ball joints, and the pillars and the legal pedestal were connected. Japanese Patent Laid-Open No. 1-97752 discloses a vibration-isolating floor structure in which an elastic member is interposed between a frame member surrounding the pillar and an elastic member for holding the pillar in an upright state.
（発明が解決しようとする課題）
前者の場合、免振床組があるため、建物床からフロアパ
ネルまごの高さが高くなり、その分だけ建物の階高が高
くなる。(Problem to be Solved by the Invention) In the former case, since there is a vibration-isolating floor assembly, the height of the floor panel is higher than the building floor, and the floor height of the building is increased accordingly.

めに倒れ、フロアパネルは振動する。(Function) Since the present invention is configured as described above, during an earthquake,
The rubber parts that fix the upper and lower ends of the support of the vibration-isolating floor to the floor panel and the building are elastically deformed, causing the support to fall diagonally and the floor panel to vibrate.
而して地震が終ったとき、前記ゴムの弾性力によってフ
ロア、パネルは水平方向の復元力が与えられ、旧位に復
し、免振効果が発揮される。When the earthquake is over, the elastic force of the rubber provides horizontal restoring force to the floor and panels, allowing them to return to their original positions and exhibiting a vibration isolation effect.
