SOUNDPROOF FLOOR STRUCTURE, SOUNDPROOF METHOD OF FLOOR, AND SOUNDPROOF MATERIAL
PROBLEM TO BE SOLVED: To provide a soundproof floor structure which can reduce a superimposed floor impact sound by a simple structure.SOLUTION: A soundproof floor structure is constructed which constrains a plate-shaped soundproof material 1 including an elastic body, and also including a soft layer whose specific gravity is not lower than 1.5, and a hard layer which is laminated on and joined to at least one face of the soft layer to a floor substrate material by using a connecting tool 3 in a state that the plate-shaped soundproof material opposes and separates from a surface of the floor substrate material 2. The connecting tool is interposed between the floor substrate material and the plate-shaped soundproof material, and a region of a part of either of faces of the floor substrate material and a region of a part of a surface of the plate-shaped soundproof material are connected to each other. The elastic body may be formed of asphalt. A natural frequency of the plate-shaped soundproof material is at a degree of 5 to 50 Hz. The soft layer may be formed of metal.SELECTED DRAWING: Figure 1
【課題】簡便な構造で重量床衝撃音を低減できる防音床構造を提供する。【解決手段】弾性体を含み、かつ比重が１．５以上である軟質層とこの軟質層の少なくとも一方の面に積層して接合された硬質層とを含む板状防音材１を、床下地材２の表面と対向させて離間させた状態で、連結具３で前記床下地材に拘止する床防音構造を施工する。前記床下地材と前記板状防音材との間に前記連結具を介在させて、前記床下地材のいずれかの面の一部の領域と前記板状防音材の表面の一部の領域とを結合する。前記弾性体はアスファルトであってもよい。前記板状防音材の固有振動数が５〜５０Ｈｚ程度である。前記硬質層は金属で形成されていてもよい。【選択図】図１
