が執られて来たが、以下に示すような問題点があった。2. Description of the Related Art In a flooring material used in an apartment house or the like, a decorative veneer as shown in FIG. A method of adhering a floor material in which a back cushion material (C) is bonded and integrated to a plywood base material (B) that has been subjected to saw groove processing (A) to a concrete slab by using an epoxy resin adhesive or the like is used. Although it has been carried over, there were the following problems.
【０００３】即ち、化粧単板を接着一体化して使用する
基材に、合板を使用するため、 合板に使用される南洋材が枯渇し、コストが高くな
りつつあること。That is, since plywood is used as a base material for bonding and integrating decorative veneers, the South Sea wood used for plywood is depleted and costs are increasing.
【０００４】 軽量床衝撃音遮音を向上させるために
は、鋸溝を入れて基材部分を柔軟にすると遮音性能を向
上させる効果があるが、鋸溝を合板に入れると、合板の
力学的バランスを崩し、反りが発生する恐れがあり、こ
の傾向は、厚さが１０ｍｍ以下では顕著である。In order to improve the sound insulation of lightweight floor impact sound, it is effective to improve the sound insulation performance by making the base material part flexible by providing a saw groove, but when the saw groove is put in the plywood, the mechanical balance of the plywood is improved. May occur and warp may occur, and this tendency is remarkable when the thickness is 10 mm or less.
【０００５】 また、図３に示すように、鋸溝加工の

が殆ど無くなり、反りの発生は無くなるものの、運搬施
工時の取扱いで、図４に示したように、裂け目（Ｖ）が
生じて床材が折損してしまう恐れがある。Further, as shown in FIG. 3, if the depth (D) of sawtooth cutting is not only the orthogonal layer (B 1 ) of the plywood (B) but also the parallel layer (B 2 ) is cut too much, Although the strength in the length direction is almost eliminated and the warpage is eliminated, there is a possibility that the floor material may be broken due to a crack (V) during handling during transportation as shown in FIG.

粧単板の厚さが０．３ｍｍ程度では、基材の硬さがその
まま表面に出てしまい、そのため、通常の合板に使用さ
れるようなラワンでは、材が軟質であるため、ハイヒー
ル等の傷が付きやすかった。The surface hardness of ordinary plywood is low, and when the thickness of the decorative veneer is about 0.3 mm, the hardness of the base material appears on the surface as it is. Since the material of Lauan is soft, it was easy to get scratches such as high heels.
【０００７】そこで、表面硬度向上のために、化粧単板

比重繊維板）と合板とを貼り合わせる方法は、コストア
ップとなる上、製造工程も複雑となった。Therefore, in order to improve the surface hardness, WPC obtained by injecting and hardening a resin into a decorative veneer is used, or MDF (medium specific gravity fiber board) having a large surface hardness is laminated with plywood to form a surface material. , An example using MDF (medium specific gravity fiber board) itself as a base material was also devised, but MDF (medium specific gravity fiber board) alone is fragile and has a problem in dimensional stability, and WPC and MDF (medium density fiber board) and plywood The method of pasting together and increases the cost and complicates the manufacturing process.
【０００８】さらに、上記の基材は、遮音性能向上のた

ような問題があった。Further, in the above-mentioned base material, a cushioning material is adhered and integrated on the back surface in order to improve the sound insulation performance, but there are the following problems.

ある。As shown in FIG. 5, the back surface cushioning material (C)
Is normally 1 to 2 mm on the back when used in products.
Although the convex part (F) with a certain height (E) is installed, if the foreign matter (G) such as sand and dust is caught insufficiently, the cushioning effect will be significantly reduced. It may happen.

However, as the cushioning material (C) is restored, as shown in FIG. 9, the long columnar adhesive (h) is cured as shown in FIG. There was also a case where a squeal was generated due to the friction between the broken portions (h1).

るものである。According to the present invention, the strand board is used as the base material of the flooring material, and the board has a structure in which a large number of thin veneers are laminated. Since the actual strength is high, the possibility of problems such as squealing noise is reduced, and the strength does not drop drastically due to the depth of saw cutting like plywood. The range is larger than plywood, stable quality products can be produced even if there is some deviation during production, and low quality materials, small diameter materials, thinned wood materials, construction waste materials, etc. can be used as manufacturing raw materials, and it is possible to manufacture at low cost Further, the surface hardness of the base material is equivalent to MDF (medium specific gravity fiberboard) and harder than ordinary lauan plywood, so even if a thin decorative veneer is used, scratches such as high heels are less likely to occur. In addition, the bumps of the foam of the cushioning material are not exposed on the back surface of the product. Because, and buried by the adhesive at the time of construction,
The adhesive, which was temporarily compressed by the pressure of a rubber hammer or walking and adhered to the crushed convex root, was cured while the string was pulled into a long columnar shape as the cushioning material was restored. As shown in (1), it has a very beneficial effect such as the fact that the rubbing of the broken parts does not cause stagnation.
