FLOATING FLOOR STRUCTURE AND FLOATING FLOOR CONSTRUCTION METHOD

To provide a floating floor structure capable of supporting even when there are changes in the load of loaded items on the floating floor or changes in the placement of the loaded items, responding appropriately to the changes while providing vibration isolation.SOLUTION: The floating floor structure has multiple vibration isolators spaced apart from each other on a floor base and each having on the top thereof a support part that supports the floor slab with the floor slab floating above the floor base. The multiple vibration isolators are arranged in a manner that some of the vibration isolators support the floor slab under normal conditions and the number of vibration isolators that support the floor slab increases as the load on the floor slab increases.SELECTED DRAWING: Figure 1 【課題】浮床上の積載物の荷重変動や、積載物の配置の変動があっても、これらに好適に対応して防振しつつ支持できる浮床構造を提供すること。【解決手段】床基盤上に互いに間隔を空けて配置され、床スラブを床基盤から浮かせた状態で支持する支持部をそれぞれ上部に有する複数の防振装置を有し、複数の防振装置は、通常状態においては複数の防振装置のうちの一部の個数で床スラブを支持し、床スラブにかかる荷重の増大に応じて床スラブを支持する防振装置の個数が増加する態様で、配設されている。【選択図】図１
