【発明の詳細な説明】
（産業上の利用分野）
この発明は、住宅、ビル建築等の内装に用いられる木質
系床材において、軽量床衝撃音を低減する遮音床材に関
する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a sound insulating flooring material that reduces lightweight floor impact noise among wooden flooring materials used for the interior of houses, buildings, etc.
（従来の技術）
最近、マンション等の集合住宅や高層建築において、上
階の音が下階に響き渡るということで、これが社会問題
にまでなっている。室内で発生する会話等は隣室の場合
は、壁体を通じて間こえるが、この場合は壁面の面比重
を大きくすることでほぼ解決されてきた。しかし、床材
表面に直接与えられる衝撃音は、単に床材の面比重を大
きくすることでは解決できない。(Prior Art) Recently, in apartment complexes such as condominiums and high-rise buildings, the sound from the upper floors echoes to the lower floors, which has become a social problem. Conversations that occur indoors can be heard through the walls of adjacent rooms, but this problem has been mostly solved by increasing the surface density of the walls. However, impact noise that is directly applied to the surface of the flooring material cannot be solved simply by increasing the surface specific gravity of the flooring material.
床面を刺激する衝撃音には、重量床衝撃音と軽量床衝撃
音があり、このうち重量床衝撃音は、表面床材の種類に
は殆ど関係なく、コンクリートスラブの厚み等の建築構
造枢体に影響されるため、表面の仕上げ床材の改良だけ
では改善できない。Impact sounds that stimulate floor surfaces include heavy floor impact sound and light floor impact sound. Of these, heavy floor impact sound has little to do with the type of surface flooring material, but is due to structural factors such as the thickness of the concrete slab. Because it is affected by the body, it cannot be improved simply by improving the surface finish of the flooring material.
しかし、軽量床衝撃音は、表面床材の種類や構成に大き
く影響されるので、表面床材の改良が種々行われている
。However, since lightweight floor impact noise is greatly affected by the type and structure of the surface flooring material, various improvements have been made to the surface flooring material.
この軽量床衝撃音を改良するために、従来は床仕上げ材
としてカーペットあるいはクツションシートなどを敷い

などのメンテナンスの難しさ等の理由により、比較的掃
除等が簡単で現代的雰囲気や豪華さも惑じることのでき
る等の理由から、木質化粧床材の需要が増え、それに伴
って木質化粧床材での遮音要求が強まっている。In order to improve this lightweight floor impact sound, carpets or cushion sheets have been used as floor finishing materials in the past, but these have caused hygienic problems such as the generation of dust mites, and difficulty in maintenance such as cleaning. For various reasons, the demand for decorative wood flooring has increased because it is relatively easy to clean and can give off a modern atmosphere and luxury, and with this, the demand for sound insulation with decorative wood flooring has increased. There is.
しかし、木質化粧床材の軽量床衝撃音の低減は、なかな
か難しく、一部の商品では木質化粧床材の裏面に軽量発
泡シートや、高比重遮音シート、繊維物質等を貼着して
いるが、未だ十分な遮音効果を発揮していない。また、
木質床材としては軟らかすぎるために荷重による凹みや
、船酔と同じような気分になる等軟らかさから起きる問
題も存在する。さらに、施工面が繊維質の木質床材では
、繊維に接着材が浸透して、繊維が硬化してしまうため
に遮音性能の低下の可能性も考えられる。However, it is difficult to reduce the impact sound of lightweight flooring made of wood decorative flooring, and some products use lightweight foam sheets, high-density sound insulating sheets, fiber materials, etc. attached to the back of the wood decorative flooring. However, it still does not have sufficient sound insulation effect. Also,
Because it is too soft to be used as a wood flooring material, there are problems caused by its softness, such as denting under load and a feeling similar to seasickness. Furthermore, in the case of wooden flooring that has a fibrous construction surface, the adhesive may penetrate into the fibers and harden them, which may reduce the sound insulation performance.
また、繊維ではコンクリート面からの水分を防ぐことが
できず、結果として床材の反り等が発生しやすくなって
いる。Furthermore, fibers cannot prevent moisture from seeping in from the concrete surface, and as a result, the flooring tends to warp.
（発明が解決しようとする問題点）
そこでこの発明は、木質化粧床材にあって、なお軽量床
衝撃音が低減でき、ある程度の硬さを備える遮音床材を
提供するものである。(Problems to be Solved by the Invention) Therefore, the present invention provides a sound insulating flooring material which is a wooden decorative flooring material, can still reduce the impact sound of a lightweight floor, and has a certain degree of hardness.

化粧床材の裏面に貼着するものより構成される。(Means for Solving the Problems) This invention solves the above problems by pasting a nonwoven fabric formed into a wave shape and having sheets pasted on both sides to the back side of a wooden decorative flooring material with grooves on the back side. It consists of things that do.

みが厚くなると凹み量が大きくなるという欠点がある。(Function) Impact sound applied to the floor is attenuated, absorbed, and
It is thought that this is reduced by dispersion, etc. Moreover, the sheet pasted on both sides of the nonwoven fabric can prevent adhesives, water, moisture, etc. from entering the nonwoven fabric, and can also have the function of improving cutting properties. Furthermore, because it is formed into a firm wave shape, it is much stronger against vertical forces than non-woven fabric that is not formed. Therefore, disadvantages such as dents and feeling similar to seasickness are eliminated. In addition, in the case of a non-woven fabric that is not formed into a wave shape, a certain degree of thickness is required for sound insulation performance, but there is a drawback that the thicker the thickness, the larger the amount of dents.
なお、波状成形は不織布に限らず各種発泡体、天然繊維
等でも良い。Note that the wave-forming is not limited to nonwoven fabric, and various foams, natural fibers, etc. may be used.
次にこの発明の２〜３の実施例を遮音効果について述べ
る。Next, the sound insulation effect of two to three embodiments of this invention will be described.
