従来、中高層住宅の床には、コンクリートスラブに直接カーペット類を施工す ることが行われている。しかしながら、カーペット類を使用した場合には、張り 替えに手間がかかると共にダニ類が発生するという欠点がある。 他方、近年木質材料が我が国の気候に適するということ及び木質の素材感に対 する親しみについて見直されるに従い、木質床材を使用する傾向が強くなってい る。 Traditionally, carpets have been installed directly on concrete slabs on the floors of middle- and high-rise houses. However, when carpets are used, there is a drawback that it takes time to replace them and mites are generated. On the other hand, with the recent review of the suitability of wood materials for the climate of Japan and the familiarity with the texture of wood materials, the tendency to use wood floor materials has become stronger.
【０００３】 しかしながら、木質床材はカーペット類に比べて遮音性能が著しく劣っている ために、特に、コンクリートスラブに直接施工する直張り用木質床材の場合には 床衝撃音の階下への影響が著しく、又コンクリートスラブの不陸に対する追随性 が悪いという欠点を有していた。However, since the wooden floor material is significantly inferior in sound insulation performance to the carpets, particularly in the case of the wooden floor material for direct tensioning directly applied to the concrete slab, the influence of the floor impact sound on the downstairs is exerted. However, the concrete slab has a drawback that it has a poor trackability to the unevenness.
【０００４】 そこで、上記の欠点を解決するために木質床材の裏面に緩衝材を積層せしめて 木質床材とコンクリートスラブとの間に密着性及び制振性を持たせると共に、更 に木質床材の層中に遮音性を有する制振シートを積層せしめて木質床材自体に遮 音性能を持たせた様々な遮音性木質床材が提案されている。Therefore, in order to solve the above-mentioned drawbacks, a cushioning material is laminated on the back surface of the wooden flooring material so that the wooden flooring material and the concrete slab have an adhesive property and a vibration damping property. Various sound-insulating wooden floor materials have been proposed in which sound-damping sheets having sound-insulating properties are laminated in layers of wood to give the wood floor material sound-insulating performance.
【０００５】 又、遮音性能を高めるという観点から木質床材の裏面に切削溝を設けることが 従来から行われているが、その切削溝についての定量的な検討は未だなされてい ない。Further, from the viewpoint of improving the sound insulation performance, it has been conventionally performed to provide a cutting groove on the back surface of the wooden floor material, but the cutting groove has not been quantitatively examined yet.
【０００６】[0006]
【考案が解決しようとする課題】 本考案者等は木質床材の遮音性を改善すべく鋭意検討を重ねた結果、木質床材 を構成する層中に積層せしめる制振シートの動的バネ定数によって遮音性能が変 化すること、及び前記木質防音床材の裏面の幅方向に設ける直線状の切削溝の数 を多くする程コンクリートスラブへの追随性を良好なものとすることができる上 遮音性能をも向上せしめることができることを見出し本考案に到達した。[Problems to be Solved by the Invention] As a result of intensive investigations by the present inventors to improve the sound insulation of wooden floor materials, as a result, the dynamic spring constant of the damping sheet to be laminated in the layers constituting the wooden floor materials. The sound insulation performance is changed by the above, and the greater the number of linear cutting grooves provided in the width direction of the back surface of the wooden soundproof floor material, the better the followability to the concrete slab. The inventors have found that the performance can be improved and have reached the present invention.
【０００７】 従って、本考案の第１の目的は遮音性能に優れた木質防音床材を提供すること にある。 本考案の第２の目的はコンクリートスラブへの追随性及び遮音性能に優れた直 張り用木質防音床材を提供することにある。 本考案の第３の目的はコンクリートスラブへの追随性及び遮音性能に優れた雁 行模様を有する直張り用木質防音床材を提供することにある。Accordingly, a first object of the present invention is to provide a wood soundproof flooring material having excellent sound insulation performance. A second object of the present invention is to provide a wooden soundproof flooring material for upholstery which has excellent followability to concrete slabs and sound insulation performance. A third object of the present invention is to provide a wood soundproof flooring material for direct tensioning which has a geese pattern and is excellent in conformity to concrete slabs and sound insulation.
