この発明は木質化粧床材、特に合板床やコンクリート床
等の床下地上に施工する上張用の木質化粧床材に関する
。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a decorative wood flooring material, particularly to a decorative wood flooring material for overlaying on a subfloor such as a plywood floor or a concrete floor.
従来の技術
従来、この種の床材は、厚さ12〜15−程度の合板を
基材とし、その上面に銘木材等からなる厚さ0.5〜3

も知られている。Conventional technology Conventionally, this type of flooring has a base material of plywood with a thickness of about 12 to 15 mm, and a layer of 0.5 to 3 mm thick made of precious wood or the like on the top surface.
Generally, a decorative veneer of approximately . In addition, for flooring materials that are directly applied to concrete floors, etc., a cushioning material such as a foamed synthetic resin sheet is further attached to the underside of the base material in order to improve its conformity to the underlying surface. is also known.
そして、か\る床材の施工は、床下地上に接着剤を介し
て該床材を敷き並べ、更に要すれば周縁の接合部から釘
を打ち込んで床下地に固定することによって行われてい
る。The construction of such flooring materials is carried out by laying the flooring materials on the subfloor surface using an adhesive and, if necessary, driving nails into the joints at the periphery to fix them to the subflooring material. .
発明が解決しようとする課題
しかしながら、従来の上記のような木質化粧床材にあっ
ては、次のような固有の問題点ないしは欠点を有するも
のであった。Problems to be Solved by the Invention However, the above-mentioned conventional wooden decorative flooring materials have the following inherent problems or drawbacks.
先ず、第1に、表面に傷がつき易い点である。First, the surface is easily scratched.
このため、施工時においては慎重な取扱いと養生が要求
されるのみならず、生活者によってつけられる表面傷、
殊に土足で使用される店舗等の床にあっては、靴の踵で
表面が部分凹陥する所謂ヒールマークによって、早期に
外観体裁の悪いものとなる欠点があった。このような表
面の傷つき易さの程度は、基材の表面の硬さに大きく依

ン合板が用いられているものであり、それ自体に均一か
つ十分な表面硬さを期待することはできない。そのため
、表面部に樹脂を含浸させることによって硬くすること
も一部に試みられているが、コスト高につき、実際的で
はなかった。For this reason, not only careful handling and curing are required during construction, but also surface scratches caused by residents.
In particular, floors of stores and the like where shoes are used have the disadvantage that so-called heel marks, where the surface is partly depressed by the heel of the shoe, quickly make the floor look unsightly. It is known that the degree of susceptibility of the surface to scratches largely depends on the hardness of the surface of the base material, and that it can be improved by using a hard base material, but from a cost perspective, it is difficult to use a hard base material. Generally, lauan plywood is used, and it cannot be expected that it will have uniform and sufficient surface hardness. Therefore, some attempts have been made to make the surface hard by impregnating it with resin, but this has been impractical due to the high cost.
また、第2に、従来の床材は全体に反りとか歪を発生し
易い点である。このような形状の不安定は、基材に合板

。Second, conventional flooring materials tend to warp or distort as a whole. As long as plywood is used as the base material, this instability in shape is due to the fact that the constituent boards contain a mixture of heartwood and sapwood, which causes uneven moisture content during drying. This is something that inevitably occurs.
そして、床材にこのような反りや歪を有すると、施工に
際して周縁の雌雄の接合部の嵌合操作が行いにくいもの

面に接着し、更には釘打ちを行って反りを修正すること
などが必要となり、このように糊釘併用で施工せざるを
得ないために愈々施工能率が低下するというような重大
な問題にも発展している。If the flooring material has such warpage or distortion, it will be difficult to fit the male and female joints at the periphery during construction, which will not only reduce construction efficiency but also cause the flooring material to lie flat on the subfloor surface. In order to construct the floor, it is necessary to apply adhesive and adhere it to the subfloor surface, and also to correct the warpage by driving nails. This has also led to serious problems such as a sudden decline in construction efficiency.

ものである。In view of the above-mentioned problems, the present invention aims to make the surface hard to be damaged during construction and during living, and to have no warping or distortion, and therefore to have good workability.
This was done with the aim of achieving significant labor and time savings in construction, and creating a high-quality decorative floor.

と、を主たる改善手段の要素とするものである。Means for Solving the Problems The present invention achieves the above-mentioned objectives by, firstly, converting the material of the base material to medium density fiberboard (MDF-semi-rigid fiberboard); and secondly, The front and back sides are balanced by attaching veneers of approximately the same thickness to both the front and back sides of the material. Thirdly, in addition to the joint structure of the actual type, the outer Fourthly, the floor according to the above-mentioned items 1 to 3 was adopted. The main element of the improvement measures is that the flooring material is adhesively bonded between adjacent materials, and a laying construction method is adopted in which the floor material is not glued or nailed to the subfloor surface. That is.
而して、この発明に係る木質化粧床材は、中質繊維板か
らなる所定厚さの基板の表裏両面に、略同厚の表面化粧
単板と裏打ち単板とが貼着されてなるものである。Thus, the wooden decorative flooring material according to the present invention is formed by pasting a decorative veneer and a lining veneer of approximately the same thickness on both the front and back sides of a substrate of a predetermined thickness made of medium density fiberboard. It is.

更に、上記施工方法において、好ましくは、床材を緩衝
材シートを介して床下地上に置き敷き施工するものであ
る。Furthermore, in the above-mentioned construction method, preferably, the flooring material is placed on the subfloor surface via a cushioning material sheet.
作用
基材として用いられる中質繊維板は、材質上表面が相当
に硬い。このためこの表面硬さによって、化粧単板の表
面の耐傷性を改善し、殊に土足用床材にあっても表面に
ヒールマーク等の凹損を生じにくいものとする。The medium-density fiberboard used as the working base material has a considerably hard surface. Therefore, this surface hardness improves the scratch resistance of the surface of the decorative veneer, and makes it difficult for dents such as heel marks to occur on the surface, especially in flooring materials for shoes.
また、上記基材はそれ自体工業製品であるために材質的
に均一であり、ベニヤコア合板の場合のように材質的な
ムラを有しない。従って、それ自体に反りとか歪の発生
要因を内圧しない。Moreover, since the base material itself is an industrial product, it is uniform in material and does not have unevenness in material as in the case of veneer core plywood. Therefore, there is no internal pressure within itself that causes warping or distortion.
加えて該基材の両面に、実質的に同じ厚さの単板が貼着
されていることにより、表裏にバランスがとれ、愈々反
りや歪を生じない。従って、施工上、周縁の接合部の嵌
合操作に支障を生じることがなく、かつフラットな床仕
上げを可能とする。In addition, since veneers of substantially the same thickness are adhered to both sides of the base material, the front and back sides are balanced, and no warpage or distortion occurs. Therefore, during construction, there is no problem in fitting the peripheral joints, and a flat floor finish is possible.
更に、周縁の接合部が、相互に嵌合される雄さね部と雌
ざね部と\もに、外方に突出した接着用の下あご部とこ
れに対応する切欠段部とを有するものとなされているこ
とにより、隣接する床材相互を確実に同一平面で接合し
うると同時に、上記下あご部と切欠段部とを接着剤で接
着することによって一体的に結合施工することが容易で
ある。従って、前記の反りや歪を有しないこと5相俟っ
て、床下地面上に完全な置き敷き施工の方法で、良好な
仕上り状態の床を構成することが可能となる。Furthermore, the joint portion of the periphery has a male tongue portion and a female tongue portion which are fitted into each other, and both have a lower jaw portion for adhesion protruding outward and a corresponding notch step portion. By doing so, it is possible to reliably join adjacent flooring materials on the same plane, and at the same time, it is easy to connect the lower jaw part and the notch step part in one piece by gluing them with adhesive. It is. Therefore, in combination with the above-mentioned absence of warpage and distortion, it is possible to construct a floor with a good finish by completely laying it on the subfloor surface.
実施例

A)は、基材(1)と、その上面側に貼着された木質表
面化粧単板(2)と、同下面に貼着された木質裏打単板
(3)とで構成されている。Example In the example shown in FIGS. 1 and 2, the flooring material (
A) is composed of a base material (1), a decorative wooden veneer (2) attached to its upper surface, and a backing wooden veneer (3) attached to its lower surface.
基材(1)は、中質繊維板(MDF)からなる。中質繊

に4〜6MIn程度のものを用いるのが一般的である。The base material (1) is made of medium density fiberboard (MDF). Medium density fiberboard has a specific gravity of 0.4 to 0. 8 fiberboard,
The hardness is also quite high. Although the thickness is not particularly defined, it is generally in the range of about 3.0 to 15.0 m, particularly about 4 to 6 MIn.
表面の化粧単板(2)は、天然銘木材から得られる厚さ

。また同樹種のものであっても、コスト上、相対的に低
グレードのものを使用するのが一般的である。The backing veneer (3) is used to balance stress on the front and back sides of the flooring material in relation to the decorative veneer (2) on the surface, and therefore, it is substantially similar to the decorative veneer (2) on the surface. Although they should be of approximately the same thickness, they do not have to be exactly the same. Rather, it is also possible to use a material that is slightly thicker than the decorative veneer so as to be able to impart stress that tends to warp the base material (1). Further, as for the material, it is preferable to use the same tree species as the decorative veneer (2), but a different tree species can also be used as long as it has the same shrinkage rate. Furthermore, even if the wood is of the same species, it is common to use a relatively low grade wood due to cost reasons.
上記床材(A)は、表面の化粧単板(2)の有効寸法に
おいて一般的には303x1818皿の大きさに形成さ
れ、四周側面には、接合部が形成される。The flooring material (A) is generally formed to have a size of 303 x 1818 plates in terms of the effective dimensions of the decorative veneer (2) on the surface, and joints are formed on the four circumferential sides.

構造を併有したものとなされている。The joint part is located between two adjacent sides of the four circumferential sides of the flooring material (A).
A female tongue portion (4) is formed on the side surface of one side, and a corresponding male tongue portion (5) is formed on the side surface of the other two sides, thereby essentially having a real joint structure, and In addition, the lower part of the female groove part (4) is largely protruded outward on the two side surfaces where the female groove part (4) exists, and the protrusion width (Wl) is 8 to 15 mm, preferably about 10 mm. A lower jaw part (6) for adhesion is formed, while a wide notch is formed on the lower side of the two sides having the other male tongue part (5) to accommodate the lower jaw part (6). A notch step portion (7) having a width (W2) larger than that is formed, thereby creating a joint structure similar to a mutually interlocking joint structure.
次に、上記の床材(A)の施工方法の好ましい一例を第
3図および第4図に基いて説明する。Next, a preferred example of the method for constructing the above-mentioned flooring material (A) will be explained based on FIGS. 3 and 4.

、所望の床施工を完了しうるちのである。First, as shown in FIG. 3, a cushioning material sheet (9) made of a foamed synthetic resin sheet or the like having a predetermined thickness is laid on a subfloor surface (B) made of concrete, plywood, particle board, or the like. Then, on top of that, first
After fixing one piece of flooring material (A) and applying adhesive (8) on its lower jaw part (6), attach the next flooring material (A') to the periphery with a joint as shown in Figure 4. Assemble them so that they fit together, and fit the male and female tongue portions (4) and (5),
Connect the lower jaw part (6) to the cutout step part (7) of the adjacent flooring material (A').
Glue them together on the surface. Here, flooring (A)
Since (A') does not have any warpage, it does not cause any difficulty in the above-mentioned fitting operation of the joint portion. Moreover, the flooring material can be installed flat without any part of it rising above the base surface. Therefore, the flooring material (A) (A) is replaced by the base surface (B
), there is no need for work such as gluing the flooring materials with adhesive or nailing them from the joints. Construction has been completed.

のとしても良い。In addition, when the above-mentioned cushioning material sheet (9) is constructed on a subfloor surface having unevenness, such as a concrete floor, its use is essential in order to absorb the unevenness. The material, thickness, etc. are selected as appropriate depending on the application and location, but for example, if it is a polyolefin resin foam sheet and requires some degree of sound insulation, a thickness of about 3.0 mm is recommended. Furthermore, in cases where sound insulation is not required as much as on the first floor, a thin one with a thickness of about 1.0 mm can be suitably used. Furthermore, instead of being spread on the floor subfloor surface (B) as described above, the cushioning material sheet may be previously attached to the lower surface of the flooring material (A) with an adhesive.
