Description
【発明の詳細な説明】 〔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] (Field of Industrial Application) The present invention relates to a flooring material used for the interior of a house, particularly an apartment house.
（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。(Prior Art) In recent years, the number of apartment houses has been increasing in urban areas.
In addition, among these, not only for new construction but also for remodeling, the percentage of people who desire wood flooring is increasing for health reasons 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。However, conventional wooden floor materials, even if partially called sound insulation floor materials, do not have sufficient sound insulation performance because the lightweight floor impact sound level is about L L -55, so it cannot be said that the floor insulation It was recognized that there was a defect that some floor impact sounds were transmitted.
このため、軽量床衝撃音遮音性能の向上を図ってLL-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。For this reason, L L -50
Although products developed with the goal of being released have been released, it is often the case that one or more layers of soft foam are used for the cushioning layer, and practicality, especially bending due to the load on the floor surface (dent)
It was often recognized that there was a problem with performance.
（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 is a floor substrate capable of obtaining sufficient lightweight floor impact sound insulation performance without significantly deteriorating the practicability of the floor material, in particular, the bending performance under load. It is intended to provide wood.
（問題点を解決するための手段） 本発明の構成を一実施例に基づいて説明する。まず、第
１図に示すように、厚さ１〜２ミリ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。(Means for Solving Problems) The configuration of the present invention will be described based on an embodiment. First, as shown in FIG. 1, a projecting foam having a thickness of about 1 to 2 mm.
The plastic sheet (1) provided with (2) is adhered to the plywood (3) so that only the top end is in contact. That is, the plastic sheet (1) is integrated with the plywood (3) with the columnar foam (2) interposed therebetween.
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。The flooring material manufactured in this way has a smooth surface on both the front and back sides, but the inside is supported by the projecting foam (2) in partial dots, so the area where vibration propagates. In addition, the hardness of the plastic sheet (1) and plywood (3) and the protruding foam (2), which is a soft foam, are different, so the vibration of the vibration is more efficient than the uniformly soft sheet-shaped cushioning material. Attenuation is possible.
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ミリ程度で、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。In addition, since the front and back surfaces are smooth, there is no possibility that vibration will be directly propagated to the lower plywood (3) by being embedded in the adhesive during construction. From a practical point of view, it is not a type in which convex is processed on a soft foam plastic sheet, the thickness of the soft foam is about 1 to 2 mm, and there is little compression deformation due to load, and no foam or protruding foam Since the plastic sheet (1) and the plywood (3) have a foaming ratio lower than that of the body (2), the flexure due to the load is minimized.
尚、この発明の他の実施例の構成について第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。Incidentally, FIG. 3 shows the configuration of another embodiment of the present invention. In this case, unlike FIG. 1, a plastic having a lower expansion ratio than the non-foamed or protruding foam (2) instead of the plywood (3). The 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成を第４図に
示し、軽量床衝撃音遮音効果を第５図に示す。FIG. 4 shows the structure in which the sound insulation floor base material of the present invention is combined with the direct-adhesion type floor finishing material having a total thickness of 10 mm, and FIG. 5 shows the lightweight floor impact sound insulation effect.
（発明の効果） 本発明は以上説明したように、床材表面で発生した振動
がコンクリートスラブに伝播するのを低減させ、軽量床
衝撃音レベルの改善を行い、且つ、床が過度に軟質とな
るのを防止する効果を有する。(Effect of the invention) As described above, the present invention reduces the propagation of vibration generated on the surface of a floor material to the concrete slab, improves the lightweight floor impact sound level, and makes the floor excessively soft. It has the effect of preventing
