FLOOR SOUND INSULATION STRUCTURE
To provide a floor sound insulation structure capable of easily adjusting a frequency of an object to be insulated and capable of being installed even when an underfloor space is narrowed.SOLUTION: A floor sound insulation structure 1 comprises: a plurality of sound insulation supporting bodies 50 respectively arranged on an upper face side of a floor structural plywood 10 and elastically supporting a floor material 20; a dynamic vibration absorber 60 disposed between the plurality of sound insulation supporting bodies 50, attached to a lower face of the floor material 20, and comprising a mass 61 and a sheet-like elastic supporting members 62, 63 elastically supporting the mass 61; and an elastic contact member 70 which is disposed between the mass 61 and the lower face of the floor material 20, which is attached to one of the mass 61 and the floor material 20, which is disposed on the other of the mass 61 and the floor material 20 in a non-contact manner and which is in contact with the other of the mass 61 and the floor material 20 in a compressed state in accordance with vibration of the mass 61.SELECTED DRAWING: Figure 2
【課題】遮音対象の周波数を容易に調整することができると共に、床下空間を狭くしたとしても設置可能な床用遮音構造を提供する。【解決手段】床用遮音構造１は、床構造用合板１０の上面側にそれぞれ配列され、床材２０を弾性支持する複数の遮音支持本体５０と、複数の遮音支持本体５０の間に配置され、床材２０の下面に取り付けられ、マス６１およびマス６１を弾性支持するシート状の弾性支持部材６２，６３を備える動吸振器６０と、マス６１と床材２０の下面との間に配置され、マス６１および床材２０の一方に取り付けられ、マス６１および床材２０の他方に対して非接着で配置され、マス６１の振動に伴って圧縮された状態でマス６１および床材２０の他方に対して当接可能となる弾性当接部材７０とを備える。【選択図】図２
