SOUNDPROOF FLOOR MATERIAL AND SOUNDPROOF FLOOR STRUCTURE
PROBLEM TO BE SOLVED: To provide a soundproof floor material A which ensures a surface performance of floor material through increasing base material 1 density without forming grooves on a rear surface of the base material 1, while decreasing rigidity of the base material 1 to ensure a soundproof performance.SOLUTION: Soundproof floor material A is provided with: wooden base material 1; decorative material 6 integrally deposited on a front surface of the wooden base material 1; and cushion material 7 integrally deposited on a rear surface of the wooden base material 1, wherein the wooden base material 1 has density from 600 to 850 Kg/mand charpy impact strength in a range from 2.2 to 5.5 kJ/mmeasured in accordance with JIS K7111.SELECTED DRAWING: Figure 2
【課題】防音床材Ａにおいて、基材１の裏面に溝部を形成することなく、かつ基材１の密度を大にして床材の表面性能を確保しつつ、その基材１の剛性を低下させて、防音性能を確保する。【解決手段】防音床材Ａは、木質基材１と、この木質基材１の表面側に一体的に積層された化粧材６と、木質基材１の裏面側に一体的に積層された緩衝材７とを備え、木質基材１は、密度が６００〜８５０Ｋｇ／ｍ３でかつＪＩＳ Ｋ７１１１の規定に準じて測定されるシャルピー衝撃強さが２．２〜５．５ｋＪ／ｍ２の範囲とする。【選択図】図２
