〔発明の目的〕
（産業上の利用分野）
本発明は、住宅、特に集合住宅の内装に用いられる床材
に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a flooring material used for the interior of a house, particularly an apartment complex.
（従来の技術）
近年、都市部においては集合住宅が増加しつつある．又
、これらの中でも新築のみならずリフォームにおいても
健康上その他の理由から木質床材を希望する割合が大き
くなりつつある。(Conventional technology) In recent years, apartment complexes are increasing in urban areas. Furthermore, among these, an increasing proportion are requesting wooden flooring not only for new construction but also for renovations, for health and other reasons.
しかし、従来の木質床材は、一部を除いて遮音床材と称
する床材でも、軽量床衝撃音レベルがＬＬ−５５程度で
あるため、遮音性能が充分であるとは言えず、階下に若
干の床衝撃音が伝わる欠点が認められていた．
このため、軽量床衝撃音遮音性能の向上を図ってＬｔ−
５０を目標として開発された製品も発売されているが、
緩衝層に軟質な発泡体を１又は２層以上用いている場合
が多く、実用性、特に床材表面への荷重による撓み（凹
み）性能に問題がある場合が多く認められた。However, with the exception of some conventional wood flooring materials, even those that are called sound insulating flooring materials have a lightweight floor impact sound level of about LL-55, so it cannot be said that their sound insulation performance is sufficient. The drawback was that some floor impact noise was transmitted. For this reason, the Lt-
Although products developed with a target of 50 are on sale,
In many cases, one or more layers of soft foam are used for the buffer layer, and there are often problems with practicality, particularly with respect to the ability to bend (dent) due to loads applied to the surface of the flooring material.
（発明が解決しようとする問題点）
本発明は、床材の実用性、特に、荷重による撓み性能を
大幅に悪化させることなく、充分な軽量床衝撃音遮音性
能を得ることの可能な床下地材を提供しようとするもの
である。(Problems to be Solved by the Invention) The present invention provides a flooring material that can obtain sufficient light-weight floor impact sound insulation performance without significantly deteriorating the practicality of the flooring material, particularly its deflection performance under load. The aim is to provide materials.
（問題点を解決するための手段） 本発明の構戒を一実施例に基づいて説明する。 (Means for solving problems) The structure of the present invention will be explained based on one embodiment.
まず、第１図に示すように、厚さ１〜２くり程度の突起
状発泡体（２）の設置されたプラスチックシート（１）
を頂端部のみが接するように合板（３）に接着する。即
ちプラスチックシート（１）が柱状発泡体（２）を挟ん
で合板（３）と一体化した構造となる。First, as shown in Figure 1, a plastic sheet (1) with a protruding foam (2) about 1 to 2 mm thick is installed
Glue it to the plywood (3) so that only the top ends touch. That is, the structure is such that the plastic sheet (1) is integrated with the plywood (3) with the columnar foam (2) in between.
このようにして製作された床下地材は、表・裏共に平滑
な表面を有しながら、内部は突起状発泡体（２）により
部分的な点状で支持されるため、振動の伝播する面積が
小となり、また、プラスチックシート（１）及び合板（
３）と軟質な発泡体である突起状発泡体（２）の硬さが
異なるため、均一に軟質なシート状緩衝材より効率良く
振動の減衰が可能であるまた、表・裏共に平滑であるた
め、施工時において、接着剤により埋没して、振動が直
接下部の合板（３）に伝播することもない。実用面でも
、単に軟質な発泡プラスチックシートに凸を加工したタ
イプではなく、軟質な発泡体の厚さは１〜２旦り程度で
、あとは荷重による圧縮変形が小の、無発泡又は突起状
発泡体（２）より低発泡倍率のプラスチックシート（１
）及び合板（３）であるので荷重による撓みも最少限に
とどまる。The flooring material manufactured in this way has smooth surfaces on both the front and back sides, but the interior is supported in partial dots by the protruding foam (2), so it has an area where vibrations propagate. becomes smaller, and plastic sheet (1) and plywood (
Because the hardness of the protruding foam (2), which is a soft foam, is different from that of the cushioning material (3), it is possible to damp vibrations more efficiently than the uniformly soft sheet-like cushioning material.In addition, both the front and back sides are smooth. Therefore, during construction, it is buried in the adhesive and vibrations do not directly propagate to the plywood (3) below. In practical terms, it is not simply a type of soft foamed plastic sheet with convexities, but a soft foamed material with a thickness of about 1 to 2 degrees, and a non-foamed or protruded type that is less susceptible to compression deformation under load. A plastic sheet (1) with a lower expansion ratio than the foam (2)
) and plywood (3), so deflection due to load is kept to a minimum.
尚、この発明の他の実施例の構戊について第３図に示す
と、この場合第１図と異なり、合板（３）の代わりに無
発泡又は突起状発泡体（２）より低発泡倍率のプラスチ
ックシート（４）を用いたものである。The structure of another embodiment of the present invention is shown in FIG. 3. In this case, unlike in FIG. A plastic sheet (4) is used.
そして、本発明の遮音床下地材と、総厚１０ミリの直貼
りタイプの床仕上げ材を組合わせた場合の構或を第４図
に示し、軽量床衝撃音遮音効果を第５図に示す。Figure 4 shows the structure when the sound insulating floor base material of the present invention is combined with a direct-applying type floor finishing material with a total thickness of 10 mm, and Figure 5 shows the impact sound insulation effect of a lightweight floor. .
