考案の分野
本考案は、中質繊維板を基材とした床パネルに
関し、耐たわみ性と、吸湿、給水による反りを防
止した複合床パネルに関する。[Detailed Description of the Invention] Field of the Invention The present invention relates to a floor panel made of medium-density fiberboard as a base material, and relates to a composite floor panel that has flexibility and prevents warping due to moisture absorption and water supply.
従来の技術
従来、実加工された木口を有する繊維板の表面
に突板を貼り合わせた床パネルは知られている。BACKGROUND ART Conventionally, floor panels are known in which a veneer is bonded to the surface of a fiberboard having an actual finished end.
一般に、吸湿、給水による繊維板の膨脹率は、
単板の繊維方向における膨脹率の３〜４倍にも達
する。このために、上述の如き複合床パネルでは
表面側（突板側）が凹となる様な反りが生ずる傾
向がある。 Generally, the expansion rate of fiberboard due to moisture absorption and water supply is
The expansion rate in the fiber direction of the veneer reaches 3 to 4 times. For this reason, the above-mentioned composite floor panel tends to warp so that the surface side (veneer side) becomes concave.
床パネルは、その使用目的から、曲げ強度、耐
たわみ性が良いことが要求される。従つて基材と
して中質繊維板（比重0.4〜0.8）を用いる場合に
は、基材自体を厚くする必要がある。さもなけれ
ば、比重の高い硬質繊維板を用いなければならな
い。これは、コスト高となり、また重量が大きく
なるので施工性が悪い。 Floor panels are required to have good bending strength and deflection resistance due to their intended use. Therefore, when medium density fiberboard (specific gravity 0.4 to 0.8) is used as a base material, it is necessary to make the base material itself thick. Otherwise, high density hard fiberboard must be used. This increases cost and increases weight, resulting in poor workability.
考案の目的
従つて、本考案の目的は、吸湿、給水による反
りの少ない複合床パネルを提供することである。Purpose of the invention Therefore, the purpose of the present invention is to provide a composite floor panel that is less likely to warp due to moisture absorption or water supply.
本考案の他の目的は、中質繊維板を基材として
用い、軽量で曲げ強度及び耐たわみ性にすぐれた
複合床パネルを提供することである。 Another object of the present invention is to provide a lightweight composite floor panel that uses medium-density fiberboard as a base material and has excellent bending strength and deflection resistance.
本考案のその上更なる目的は、一定の曲げ強
度、耐たわみ性を有する軽量化された複合床パネ
ルを提供することである。 A further object of the present invention is to provide a lightweight composite floor panel with constant bending strength and deflection resistance.

板の厚みとを略等しくなるよう調整する。Structure of the invention In this invention, a medium-density fiberboard is used as a base material, a low-grade wood veneer is pasted on the surface, a veneer is pasted on the surface, and a low-grade wood veneer is pasted on the back side of the base material. At this time, the fiber direction of the low-grade wood veneer and the veneer attached to the front and back sides of the base material is oriented in the longitudinal direction of the base material. Desirably, the total thickness of the low-grade wood veneer and the veneer on the front side is adjusted to be approximately equal to the thickness of the low-grade wood veneer on the back side.
これにより、吸湿、給水による反りが防止さ
れ、また中質繊維板基材の厚さを比較的薄くし、
軽量化しても、曲げ強度、耐たわみ性を高く維持
することができる。 This prevents warping due to moisture absorption and water supply, and also allows the thickness of the medium density fiberboard base material to be relatively thin.
Even if the weight is reduced, bending strength and deflection resistance can be maintained high.
実施例の説明

得られたものであつて良い。Description of Examples The base material 1 used in the present invention has a specific gravity of 0.4 to 0.8.
These fiberboards may be obtained by molding softwood fibers, hardwood fibers, or mixed fibers thereof as raw materials.
基材１の表裏面に、尿素、酢酸ビニル、エチレ

接着剤を用いて低級木質単板３，４を貼着する。
これらの単板は、繊維方向を基材の長手方向に配

ーズ、ラワンなどの樹材を切削して得られる単板
である。しかし乍ら他の種類の樹材を切削した単
板であつても良い。 Low-grade wood veneers 3 and 4 are attached to the front and back surfaces of the base material 1 using an adhesive such as urea, vinyl acetate, ethylene vinyl acetate, SBR, or vinyl urethane.
These veneers are preferably attached with the fiber direction oriented in the longitudinal direction of the base material. The low-grade wood veneer mentioned here is a veneer obtained by cutting wood such as spruce, china, hemlock, fir, agacheese, and lauan. However, a veneer cut from other types of wood may also be used.
表面に貼り合わされる突板２は、ケヤキ、ヒノ
キ、スギ、ローズウツド、チーク、マホガニー、

得られる。これらの突板もまた表面側の低級木質

１の長手方向に配向するのが望ましい。何故なら
ば、吸湿、給水による単板の膨脹寸法は繊維方向
に於て小でり、基材の膨脹寸法は長手方向におい
て大であるからである。 The veneer 2 to be pasted on the surface is made of zelkova, cypress, cedar, rosewood, teak, mahogany,
It is obtained by cutting wood that is generally called precious wood, such as cherry tree. These veneers are also adhered to the surface of the low-grade wood veneer 4 on the front side using the same adhesive as described above. At this time, it is desirable that the fiber direction of the veneer is also oriented in the longitudinal direction of the base material 1. This is because the expansion dimension of the veneer due to moisture absorption and water supply is small in the fiber direction, and the expansion dimension of the base material is large in the longitudinal direction.
基材の表裏面に貼着された低級木質繊維板３，
４と突板２とは、膨脹率の高い基材１の膨脹を抑
制する作用を有する。従つて、表面側に貼着され

裏面に貼着する低級木質繊維板３の厚みとを略等
しくして、基材１の表裏に同等の膨脹抑制力が働
くようにするのが良い。 Low-grade wood fiberboard 3 attached to the front and back surfaces of the base material,
4 and the veneer 2 have the effect of suppressing the expansion of the base material 1, which has a high expansion rate. Therefore, the total thickness of the low-grade wood fiberboard 4 and the veneer 2 attached to the front side,
It is preferable to make the thickness of the low-grade wood fiber board 3 attached to the back side substantially equal so that the same expansion suppressing force acts on the front and back sides of the base material 1.

貼着しても良い。 The thus obtained composite panel has a male fruit and a female fruit having shapes that can be fitted into each other formed on both sides of the ends along the longitudinal direction, thereby completing a composite floor panel. The actual processing does not necessarily have to be carried out after forming the composite panel, and the veneer or veneer may be attached to a base material that has been actually processed in advance.

A coating such as a colored coating may be applied as appropriate, or a veneer may be impregnated with a resin in advance, or a veneer coated with the above coating may be attached.
更に、実加工部の補強のために、実部に樹脂を
含浸させることもまた望ましい。 Furthermore, it is also desirable to impregnate the real part with a resin in order to reinforce the real part.

る。 According to the present invention, even if a relatively thin medium-density fiberboard is used, warping due to moisture absorption and water absorption can be prevented by pasting veneers on the front and back sides.In particular, the veneer on the front side By making the total thickness of the veneer and the veneer approximately equal to the thickness of the veneer on the back side, the effect is further enhanced. In particular, the latter improves the bending strength and deflection resistance of the medium density fiberboard base material, so if you want to provide the same bending strength and deflection resistance as conventional flooring materials, it is necessary to reduce the thickness of the base material. This reduces the load per unit area and improves workability.
