<P>PROBLEM TO BE SOLVED: To provide a sound insulation floor structure in which the floor structure having specification with high sound insulation performance can be easily and compactly formed by combining mainly commercially available materials. <P>SOLUTION: A sound insulation floor structure, which is provided in a floor part between an upper floor 30 and a lower floor 31 in a wooden house building, is supported by floor support members 11a, 11b. The sound insulation floor structure comprises: a floor substrate material 12 laid on the floor support members; a sheet material 13 having elastic force laid on the top face of the floor substrate material 12; a sound insulation laminate plate-like body 14 laid on the top face of the sheet material 13 having elastic force; and a floor finishing material 15 laid on the top of the sound insulation laminate plate-like body 14. The sound insulation laminate plate-like body 14 is formed by laminating a woody surface material 16, a lower layer heavy surface material 17, an asphalt, rubber, or resin elastic surface material 18, and an upper layer heavy surface material 19 in this order and jointing and integrating them together. The elastic sheet material 13 is interposed between the sound insulation laminate plate-like body 14 and the floor substrate material 12, thus making a floating floor structure of the sound insulation floor structure. <P>COPYRIGHT: (C)2013,JPO&INPIT |
