VIBRATION-PROOF MEMBER FOR FLOATING FLOOR STRUCTURE
PROBLEM TO BE SOLVED: To provide a vibration-proof member of an excellent sound insulation effect for a floating floor structure.SOLUTION: A vibration-proof member 10 for a floating floor structure comprises a substrate 14 installed on a floor structure 22 for supporting a movable load on a floor body 20, and a cushioning body 12 that supports a load of ready-mixed concrete that forms the floor body 20 by being cast on the floor structure 22 to fill a gap between the substrates 14. The substrate 14 is made of polyurethane foam of a hardness that may support the movable load, and the cushioning body 12 is made of soft polyurethane foam. A hardness of the cushioning body 12 is set lower than that of the substrate 14, at 0.18 N/cmor greater and so as to support a load of the ready-mixed concrete corresponding to a thickness of the ready-mixed concrete. A dynamic spring constant of the cushioning body 12 is set to be 11.0×106 N/mor smaller, on a condition that the hardness corresponding to the thickness of the ready-mixed concrete is ensured.SELECTED DRAWING: Figure 2
【課題】遮音効果に優れた浮床構造用防振材を提供する。【解決手段】浮床用防振材１０は、床構造体２２の上に載置されて床体２０の積載荷重を支持する支持体１４と、この支持体１４の間を埋めるように床構造体２２上に配設され、床体２０をなす生コンクリートの荷重を支持する緩衝体１２とから構成される。支持体１４は、積載荷重を支持し得る硬さのポリウレタンフォームから構成され、緩衝体１２は、軟質ポリウレタンフォームから構成される。緩衝体１２の硬さは、支持体１４よりも柔らかく、０．１８Ｎ／ｃｍ２以上でかつ生コンクリートの厚みに応じた生コンクリートの荷重を支持し得るよう設定される。緩衝体１２は、生コンクリートの厚みに応じた硬さを満たす条件で、動的ばね定数が１１．０?１０６Ｎ／ｍ３以下になるよう設定される。【選択図】図２
