Description

【発明の詳細な説明】 [産業上の利用分野] この発明はコンクリート床材に直接施工するに適した遮音性木質系床材に関する。 DETAILED DESCRIPTION OF THE INVENTION [Field of the Industrial] This invention relates to sound insulation Wooden flooring which is suitable for construction directly concrete flooring.

[従来技術] 従来、中高層住宅の床は、コンクリート床にカーペット類をフェルトを介して直接貼付けたものが多かった。 [Prior art] Conventionally, the floor of the mid-to-high-rise residential, were often those pasted directly through the felt the carpeting to the concrete floor. しかし、カーペット類は汚れやすいうえ、ダニの発生が問題となっていた。 However, after that easy carpeting is dirty, the occurrence of ticks has been a problem.

そのため、カーペット類を貼る代わりにコンクリート床に、裏面厚み2mm位の発泡ポリウレタンシートを貼着した木質系床材を直接貼付けて床を構成するように変わってきたが、木質系床材はカーペット類に比べ遮音性に劣っているため、居住性を損なうという欠点があった。 Therefore, the concrete floor instead pasting carpeting, but the wood flooring foamed polyurethane sheet was stuck to the back surface thickness 2mm position directly attached Ke to have changed so as to constitute a floor, wood-based flooring carpeting since the poor sound insulation compared with, there is a drawback that impairs comfort.

[発明が解決しようとする課題] 本発明者は上述した課題を解消し、遮音性のすぐれた木質系床材を提供することを目的とするために日々研究した結果、発泡シートと基布に綿状繊維をからませた緩衝材を貼合わせた材料が遮音性向上に有効であることを知ってこの発明を完成した。 [INVENTION Problems to be Solved] The present inventors have solved the above problems, the results were studied daily for an object to provide a sound insulation excellent wood-based flooring, the foam sheet and the base fabric material laminated cushioning material which entangle the cotton-like fibers are know to be effective in sound insulation improved complete this invention.

[課題を解決するための手段] この発明は、木質板の裏面に発泡シート、および基布に綿状繊維をからませた緩衝材が順次貼着されていることを特徴とする遮音性木質系床材に係る。 [Means for Solving the Problems] The present invention, sound insulation wood, characterized in that the rear surface to the foam sheet of the wood board, and a cushioning material which entangle the cotton-like fibers in the base fabric are sequentially adhered according to the floor material.

以下、図面により本発明の遮音性木質系床材について詳述する。 It will be described in detail below sound insulating wooden flooring of the present invention with reference to the drawings. 第1図において、1は木質板であり、この木質板1の裏面に発泡シート2、および基布3に綿状繊維4 In Figure 1, 1 is a wood board, flocculent fiber 4 to the wood board foam sheet 2 to the back surface of 1, and the base fabric 3
をからませた緩衝材5が順次貼着されている。 It is successively attached a buffer material 5 entangle the.

上記木質板1としては、合板、パーティクルボード、ハードボード、LVL(平行合板)などをあげることができ、その表面に銘木単板、化粧合成樹脂シートを貼着したり、塗装を施して化粧層を形成してもよい。 As the wood board 1, plywood, particle board, hardboard, etc. may be mentioned. LVL (parallel plywood), precious wood veneer on its surface, or adhering a decorative synthetic resin sheet, the decorative layer painted it may be formed.

また、発泡シート2としてはポリウレタン樹脂、ポリエチレン樹脂、合成ゴム等の合成樹脂製発泡シートあるいは天然ゴムの発泡シートが使用できる。 Further, the foamed polyurethane resin as a sheet 2, a polyethylene resin, the foamed sheet of synthetic resin foam sheet, or natural rubber, such as synthetic rubber can be used. 厚さは1〜3mm Thickness 1~3mm
が好ましいが、これに限定されるものではない。 It is preferred, but is not limited thereto.

基布3に綿状繊維4をからませた緩衝材5に使用する基布としては、ポリエチレンやポリプロピレン等の合成樹脂製の織布が好ましく、また、綿状繊維4としては、ナイロン、ポリエステル、ポリプロピレン等の合成樹脂繊維が防水および耐久性の点で好ましいが、これらに限定されるものではない。 The base fabric for use in the buffer 5 which entangle the cotton-like fibers 4 to the base fabric 3 made of a synthetic resin fabric such as polyethylene and polypropylene are preferred, and as the floss 4, nylon, polyester, preferable because the synthetic resin fibers are waterproof and durable such as polypropylene, but is not limited thereto. この基布3は綿状繊維4のみでは腰がなくて取り扱いにくいので製造時に取り扱いやすくする働きもあるが、床材施工時に床材を適宜大きさに切断する際に綿状繊維4が鋸目につまったり、ほこり状態になって散逸することを防止している。 This base fabric 3 is only floss 4 also serves to facilitate handling during manufacture so difficult to handle without the hips, fluffy fibers 4 saw eye in cutting the flooring appropriately size when flooring construction or jammed in, so as to prevent the dissipation become dust state. また発泡シート2は緩衝材5の表面に発泡樹脂組成物を塗布した後発泡させて形成されてもよいし、緩衝材5は貼着される前に形成されていてもよい。 The foam sheet 2 may be formed by foaming after applying the surface foamed resin composition of the buffer material 5, the buffer material 5 may be formed prior to being bonded. 両者の貼着後の厚みは4〜10mm The thickness of the post-sticking of both 4~10mm
が好ましい。 It is preferred. 厚みが薄過ぎると遮音効果に乏しく、厚みが厚過ぎると経済的にも問題があるが、住宅の改築時に床板が厚過ぎて敷居よりも高くなり、実質的に施工できない状態となったり、床板の上を歩く時に床板の沈みが大きくなる欠点がある。 Poor in the sound insulation effect thickness is too thin, or there is a problem in the thickness is too thick economic, and floor is too thick at the time of housing renovation becomes higher than the threshold, a state that can not be substantially construction, floorboards there is a drawback that sinking of the floor plate is increased when the walk on.

木質板1と発泡シート2の間に遮音性、制振性または緩衝性を有するシート6と中間木質板7を挟み入れてもよい。 Sound insulation between the wood board 1 and the foamed sheet 2 may be inserted sandwiched sheet 6 and the intermediate wooden plate 7 having a damping or cushioning properties. この場合木質板1および中間木質板7の厚みは2.5 In this case, the thickness of the wood board 1 and the intermediate wood board 7 2.5
〜4.0mmが好ましいがこれに限定されるものではない。 ~4.0mm is preferred but not limited thereto.
あまり厚みが薄過ぎると床板としての剛性が問題になり、厚過ぎると価格もさることながら、運搬、施工時に支障を来す恐れがある。 Too much will rigidity is a problem as is too thin thickness of the floor plate, even more than if too thick price, transport, which can cause a problem at the time of construction.

上記木質板1の裏面に貼り合わせる遮音または制振シートとしては、粉末鉛入塩ビシート、無機粉末充填ゴムシート、塩ビシート等が挙げられ、厚さ0.8〜2mmのものが好ましい。 The sound insulation or vibration damping sheet bonded to the back surface of the wood board 1, a powder of lead Nyushio Bishito, inorganic powder filled rubber sheet, PVC sheet, and the like, having a thickness of 0.8~2mm are preferred. また、緩衝性シートとしては天然ゴム発泡シートやオレフィン系発泡シート等の緩衝性のあるシートであればよく、厚みは1〜2mmが好ましい。 Further, as long as the cushioning sheet a sheet a buffering property, such as natural rubber foam sheet or olefin foamed sheets, thickness 1~2mm is preferred.

さらに、中間木質板7として有孔木質板7aを使用すれば遮音性がさらに向上する。 Furthermore, sound insulation can be further improved by using a perforated wood board 7a as an intermediate wood plate 7. 有孔木質板7aの孔直径は5〜15mmが好ましいがこれに限定されるものではない。 Pore ​​diameter of porous wood board 7a is not intended to but preferably 5~15mm limited thereto.

なお、第4図に示したように表層の木質板、遮音性、制振性または遮音性を有するシートおよび中間木質板を一体化したものを小割して組み合わせた木質板の方が、小割しない大判サイズの木質板より遮音性が優れている。 Incidentally, wood board surface layer as shown in FIG. 4, sound insulation, better damping or wood board in combination with a small split those integrated sheets and intermediate wood board having a sound insulation, small sound insulation than wood board of large format that does not divide is excellent.
これは音が小割された部分で伝播しにくくなるためと考えられる。 This may be because the sound is less likely to propagate in a small split portion. 上記のように小割した木質板は、その木口面に若干の折曲ができるようなゆるめのさね加工が施され、さね継ぎによって生じる裏面の溝内に硬化後可撓性を有するホットメルト樹脂8を流し込んで接合され、その裏面全体に発泡シート2、および基布3に綿状繊維4 Small split was wood board as described above, the processing I Is loose as a butt end surface may slightly bent is subjected, hot having a cured after flexibility on the rear surface of the groove caused by the tongue and groove are joined by pouring melt resin 8, the foamed sheet 2, and cotton-like fiber 4 to the base fabric 3 on the entire back surface thereof
をからませた緩衝材5が貼り合わされている。 Is bonded cushioning material 5 entangled the.
