Description

【０００１】
【発明の属する技術分野】
本発明は、建物の室内の床面に配設される床材に関するものである。
【０００２】
【従来の技術】
従来より、住宅等の建物室内の床面には、木質の床材がよく用いられている。これは、木材の合板からパネル状の床材を複数形成し、この床材を床に敷詰めるものである。床材の表面や裏面には、防湿処理が施してある。
【０００３】
このような従来の床材は、側面の木口には防湿処理が施されていないため、木口からの吸湿・吐湿によって床材の湿度（含水率）変化が生じるものの、湿度変化による床材の伸縮率は小さく床に敷詰めた後で反り・突き上げ等が発生することはないものであった。ところが、最近は樹木の伐採制限等によりこのような合板を使用することが困難になってきており、合板の代替品として、複数の木屑片を固めて形成した削片板や、木材を一度解繊してパルプ状に形成した木質繊維板等が使用される傾向にある。
【０００４】
このような木質繊維板や木材削片板は、表１に示すように吸湿・吐湿による伸縮率が合板よりも大きいものであり、これらより上記のような床材を形成して床に敷詰めた場合、伸縮によって反り・突き上げ等が発生するという問題があった。そこで、木質繊維板や木材削片板からなる床材の側面の木口に防湿処理することが考えられた。
【０００５】
【表１】

【０００６】
ところで、上述したような床材は、床に複数敷詰めてほぼ面一な床面を形成するものであるが、床材の側面にはそれぞれ雄実と雌実が形成されており、この雄実と雌実の嵌合によって隣接する床材が接合されるものである。
【０００７】
床材の木口への防湿処理としては、合成樹脂からなる防湿性を有するシートを貼着することがまず考えられるのであるが、このようなシートは薄くて保形性がないものであって、床材の実が形成された側面に貼着する作業は困難であると共に、このようなシートを実の如く凹凸のある面に貼着して施した防湿処理は不十分なものであった。
【０００８】
【発明が解決しようとする課題】
本発明は上記の点に鑑みてなされたものであり、その目的とするところは、側面に実が形成された吸湿性を有する材料からなる床材の前記側面に、容易に迅速に十分な防湿処理を施すことのできる床材を提供することを課題とするものである。
【０００９】
【課題を解決するための手段】
上記課題を解決するために本発明に係る床材は、吸湿性を有する基板部１１の上面に突板１２を貼着してなる床板部１の側面１ａに実２を形成し、床板部１の上面に透明又は半透明な上面防湿層３を貼着し、床板部１の実２を形成した側面１ａに該側面１ａに沿う形状をした自己保形性を有する金属箔で形成した防湿性部材４を貼着すると共に、上面防湿層３又は防湿性部材４を貼着していない床板部１の表面に防湿層５を形成して成ることを特徴とするものである。このような構成とすることで、床材の実２が形成された側面１ａに自己保形性を有する防湿性部材４を貼着することで、この側面１ａに容易に迅速に防湿処理を施すことが可能となると共に床材の表面を防湿性を有する部材で確実に隙間無く被覆することが可能となって、防湿処理として十分なものとすることができ、この時、防湿性部材４を金属箔で形成することで容易に形成可能となる。
【００１０】
また、基板部１１を木質繊維板と木材削片板の一方又は両方で形成することが好ましい。このような構成とすることで、最近の傾向としての脱合板化に対応することが可能となる。
【００１３】
【発明の実施の形態】
以下、本発明の一実施形態について添付図面に基づいて説明する。
【００１４】
本発明の床材は、基板部１１とこの基板部１１上面に貼着する突板１２とで主体となる床板部１が形成される。
【００１５】
基板部１１は、吸湿性を有する材料で形成され、本実施形態では、ＭＤＦやＨＤＦ等の木質繊維板や、木材削片板（所謂パーティクルボード）や、あるいはＷＰＢからなる平面視矩形状をしたものである。この基板部１１の表面には、化粧板としての突板１２が貼着される。突板１２は、基板部１１と同様に木質材料で形成されるもので、湿式で形成されるものであれば厚さ０．２〜０．５ｍｍ程度、乾式で形成されるものであれば厚さ１ｍｍ程度である。突板１２は平面視において基板部に重なるように貼着され、突板１２の表面側（上面側）には木目模様等の模様（図示せず）が形成してあり、床材が床に配設された際に室内側から見えるものである。このようにして、基板部１１の上面に突板１２を貼着して床材の主体となる床板部１が形成してある。
【００１６】
この床板部１は、平面視における矩形状の四側面１ａに実２が形成してある。実２は、雄実２ａ又は雌実２ｂからなるもので、それぞれの面にいずれかの実２ａ，２ｂが形成される。本実施形態においては四側面１ａの全面に形成してあるが、特にこれに限定されるものではなく、一部の側面１ａにのみ形成してあってもよい。
【００１７】
このような床板部１には、上面（即ち突板１２の上面）に上面防湿層３として防湿性シート３１を貼着するものである。この防湿性シート３１は、ＰＰ（ポリプロピレン），ＰＥ（ポリエチレン）等の合成樹脂フィルムを熱融着するもので、例えばＰＰの場合は１８０℃前後で熱溶着し（因みにＰＰの融点は１６０℃〜１７０℃）、ＰＥの場合は１２０℃前後（因みにＰＥの融点は９５℃〜１１０℃）で熱溶着するものである。この防湿性シート３１は、木質材料で形成されて吸湿性を有する床板部１が吸湿しないように表面に貼着するものである。本実施形態では、防湿性シート３１はＰＰやＰＥを用いるものであるが、特にこのように限定されるものではなく、透湿性を有さないかあるいは透湿性が小さな材料であればよい。また、この上面防湿層３としての防湿性シート３１は、透明か半透明に形成するものであり、この防湿性シート３１を貼着した突板１２の上面の模様が、この防湿性シート３１を介して室内側から見えるようにしてある。
【００１８】
また、床板部１の下面にも、上述した上面防湿層３と同様に防湿層５としての防湿性シート５１を貼着するものである。本実施形態では、この防湿性シート５１も上面防湿層３としての防湿性シート３１と同様にＰＰやＰＥを用いるものであるが、特にこのように限定されるものではなく、透湿性を有さないかあるいは透湿性が小さな材料であればよい。また、上面防湿層３としての防湿性シート３１のように透明か半透明である必要はないものである。
【００１９】
また、床板部１の実２を形成した側面１ａには、自己保形性を有する防湿性部材４を被覆するものである。防湿性部材４は金属箔よりなり、この金属箔を実２に当接する部分は実２と同形状に折曲して、実２を含む側面１ａ全面に沿うように形成するものである。本実施形態においては防湿性部材４は金属箔よりなるものであるが、特にこれに限定されるものではなく、防湿性及び自己保形性を兼ね備えるものであればよい。
【００２０】
次に、上記のような上面防湿層３及び防湿層５としての防湿性シート３１，５１と、防湿性部材４とを床板部１に貼着する方法について説明する。
【００２１】
上面防湿層３としての防湿性シート３１を床板部１の上面（即ち平面視における床板部１）より大きく形成し、防湿層５としての防湿性シート５１を床板部１の下面（同じく平面視における床板部１）より大きく形成する。これらの防湿性シート３１，５１を平面視において床板部１が中に配置されるように床板部１の上面と下面とにそれぞれ貼着すると共に、防湿性シート３１，５１の周端縁３１ａ，５１ａを床板部１の側面１ａに貼着する。この際の貼着は上述したように熱溶着により行う。次に、防湿性部材４を床板部１の側面１ａに貼着する。防湿性部材４は、予め金属箔を折曲して実２を含む側面１ａに沿うような形状に形成してあり、実２を含む床板部１の側面１ａに沿わせて貼着する。この時、防湿性部材４の周端縁４ａは上記防湿性シート３１，５１の外表面に貼着し、防湿性部材４と防湿性シート３１，５１との間に湿気が侵入する隙間が生じるのを防止するものである。なお、防湿性部材４の床板部１の側面１ａ及び防湿性シート３１，５１への貼着は、両面テープのようなテープによるのが好ましい。合成ゴム系接着剤等の速乾性の接着剤も使用可能であるが、トルエン等が含まれるため、ＶＯＣ問題上好ましくない。
【００２２】
以上のような構成とすることで、上面防湿層３及び防湿層５と、防湿性部材４とを床板部１の表面に貼着し、床板部１の表面が防湿性を有するもので被覆されたことで、床板部１が吸湿・吐湿して伸縮することによる反り・突き上げの発生を防止することができるものでありながら、防湿性部材４の実２を形成した板部材１の側面１ａへの貼着は、実２を含む側面１ａに沿うような形状に防湿性部材４を形成することで、予め上記形状に保形されている防湿性部材４を該側面１ａに沿って当接させて貼着するだけで、容易に迅速に作業を行うことが可能となると共に、防湿処理として十分なものとすることができる。
【００２３】
なお、本実施形態では、平面視矩形上をした床板部１の四側面に実２を形成したが、四側面のうちの一部の側面に実２を形成し、この実２を形成した側面にのみ防湿性部材４を貼着し、実２を形成していない側面には、床板部１の下面に貼着した防湿性シート５１と同様の防湿層５を形成するようにしてもよい。
【００２４】

【００２５】
また請求項２記載の発明にあっては、上記請求項１記載の発明の効果に加えて、基板部を木質繊維板と木材削片板の一方又は両方で形成したので、最近の傾向としての脱合板化に対応することが可能となる。

BACKGROUND OF THE INVENTION
The present invention relates to a flooring disposed on a floor surface in a room of a building.
[0002]
[Prior art]
Conventionally, a wooden floor material is often used for a floor surface in a building room such as a house. In this method, a plurality of panel-like floor materials are formed from wood plywood, and the floor materials are spread on the floor. Moisture-proofing is applied to the front and back surfaces of the flooring.
[0003]
In such a conventional flooring, the moisture at the side end is not treated with moisture, so the moisture (moisture content) of the flooring changes due to moisture absorption and moisture absorption from the end, but the flooring of the flooring due to humidity change The expansion / contraction rate was small, and no warping or thrusting occurred after laying on the floor. However, recently it has become difficult to use such plywood due to tree cutting restrictions, etc., and as a substitute for plywood, shards made by solidifying multiple pieces of wood chips and wood are once solved. There is a tendency to use a wood fiber board or the like which is formed into a pulp shape by fibering.
[0004]
As shown in Table 1, such wood fiber boards and wood chipboards have a higher expansion and contraction rate due to moisture absorption and moisture absorption than plywood, and the floor material as described above is formed and laid on the floor. When packed, there has been a problem that warpage, push-up, etc. occur due to expansion and contraction. In view of this, it has been considered to apply a moisture-proofing treatment to the side end of the floor material made of wood fiber board or wood chipboard.
[0005]
[Table 1]

[0006]
By the way, the floor materials as described above are laid on the floor to form a substantially flush floor surface, and male and female berries are formed on the side surfaces of the floor material. Adjacent flooring materials are joined by fitting the fruit and the fruit.
[0007]
As a moisture-proof treatment to the mouthpiece of the floor material, it is first considered to stick a moisture-proof sheet made of a synthetic resin, but such a sheet is thin and has no shape retention, The work of attaching the floor material to the side surface on which the fruit is formed is difficult, and the moisture-proofing treatment in which such a sheet is applied to an uneven surface as in reality is insufficient.
[0008]
[Problems to be solved by the invention]
The present invention has been made in view of the above points, and the object of the present invention is to easily and quickly provide sufficient moisture-proofing to the side surface of the flooring material made of a hygroscopic material having fruit formed on the side surface. An object of the present invention is to provide a flooring that can be treated.
[0009]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the flooring according to the present invention forms the fruit 2 on the side surface 1a of the floor board part 1 formed by sticking the protruding board 12 to the upper surface of the substrate part 11 having hygroscopicity. A moisture-proof member formed of a metal foil having a self-retaining property in which a transparent or semi-transparent top moisture-proof layer 3 is attached to the top surface and a shape along the side surface 1a is formed on the side surface 1a on which the floor 2 is formed. 4, and a moisture-proof layer 5 is formed on the surface of the floor plate portion 1 to which the top moisture-proof layer 3 or the moisture-proof member 4 is not attached. By adopting such a configuration, the moisture-proof member 4 having self-shape-holding property is attached to the side surface 1a on which the floor material 2 is formed, so that the side surface 1a is easily and quickly subjected to moisture-proof treatment. It becomes possible to cover the surface of the flooring material with a moisture-proof member without gaps, and as a moisture-proof treatment , the moisture-proof member 4 can be It becomes possible to form easily by forming with metal foil.
[0010]
Moreover, it is preferable to form the board | substrate part 11 by one or both of a wood fiber board and a wood chip board. By adopting such a configuration, it is possible to cope with de-bonding as a recent trend.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.
[0014]
In the floor material of the present invention, a floor plate portion 1 that is mainly composed of a substrate portion 11 and a protruding plate 12 adhered to the upper surface of the substrate portion 11 is formed.
[0015]
The substrate portion 11 is formed of a hygroscopic material. In the present embodiment, the substrate portion 11 has a rectangular shape in plan view made of a wood fiber board such as MDF or HDF, a wood chip board (so-called particle board), or WPB. Is. A veneer 12 as a decorative plate is attached to the surface of the substrate portion 11. The protruding plate 12 is formed of a wood material like the substrate portion 11, and is about 0.2 to 0.5 mm in thickness if formed by a wet method and thick if formed by a dry method. It is about 1 mm. The protruding plate 12 is attached so as to overlap the substrate portion in plan view, and a pattern (not shown) such as a wood grain pattern is formed on the surface side (upper surface side) of the protruding plate 12, and the flooring is disposed on the floor. When viewed, it is visible from the indoor side. In this way, the projecting plate 12 is adhered to the upper surface of the substrate portion 11 to form the floor plate portion 1 that is the main component of the flooring.
[0016]
The floor plate portion 1 has a solid 2 formed on four rectangular side surfaces 1a in plan view. The fruit 2 consists of a male fruit 2a or a female fruit 2b, and either fruit 2a, 2b is formed on each surface. In this embodiment, it is formed on the entire surface of the four side surfaces 1a, but is not particularly limited to this, and may be formed only on a part of the side surfaces 1a.
[0017]
A moisture-proof sheet 31 is adhered to the floor plate portion 1 as the upper moisture-proof layer 3 on the upper surface (that is, the upper surface of the protruding plate 12). The moisture-proof sheet 31 is a material that heat-seals a synthetic resin film such as PP (polypropylene) or PE (polyethylene). For example, PP is heat-sealed at around 180 ° C. 170 ° C.), in the case of PE, heat welding is performed at around 120 ° C. (by the way, the melting point of PE is 95 ° C. to 110 ° C.). This moisture-proof sheet 31 is adhered to the surface so that the floor board portion 1 made of a wood material and having hygroscopicity does not absorb moisture. In the present embodiment, the moisture-proof sheet 31 uses PP or PE, but is not particularly limited to this, and may be any material that does not have moisture permeability or has low moisture permeability. Further, the moisture-proof sheet 31 as the upper moisture-proof layer 3 is formed to be transparent or translucent, and the pattern on the upper surface of the protruding plate 12 to which the moisture-proof sheet 31 is attached is interposed through the moisture-proof sheet 31. It can be seen from the indoor side.
[0018]
Moreover, the moisture-proof sheet | seat 51 as the moisture-proof layer 5 is stuck also to the lower surface of the floor board part 1 similarly to the upper surface moisture-proof layer 3 mentioned above. In the present embodiment, the moisture-proof sheet 51 is also made of PP or PE like the moisture-proof sheet 31 as the upper moisture-proof layer 3, but is not particularly limited as such and has moisture permeability. Any material that has no or low moisture permeability may be used. Further, unlike the moisture-proof sheet 31 as the upper moisture-proof layer 3, it is not necessary to be transparent or translucent.
[0019]
In addition, the side surface 1a formed with the fruit 2 of the floor board 1 is covered with a moisture-proof member 4 having self-retaining properties. The moisture-proof member 4 is made of a metal foil, and the portion of the metal foil that abuts against the actual 2 is bent in the same shape as the actual 2 and is formed along the entire side surface 1 a including the actual 2. In the present embodiment, the moisture-proof member 4 is made of a metal foil. However, the moisture-proof member 4 is not particularly limited to this, and any material that has both moisture resistance and self-holding property may be used.
[0020]
Next, a method for adhering the moisture-proof sheets 31 and 51 as the upper moisture-proof layer 3 and the moisture-proof layer 5 and the moisture-proof member 4 to the floor board 1 will be described.
[0021]
The moisture-proof sheet 31 as the upper moisture-proof layer 3 is formed to be larger than the upper surface of the floor plate portion 1 (that is, the floor plate portion 1 in plan view), and the moisture-proof sheet 51 as the moisture-proof layer 5 is formed on the lower surface of the floor plate portion 1 (also in plan view). It is formed larger than the floor plate part 1). The moisture-proof sheets 31 and 51 are attached to the upper surface and the lower surface of the floor plate portion 1 so that the floor plate portion 1 is disposed in the plan view, and the peripheral edge 31a of the moisture-proof sheets 31 and 51, 51a is stuck on the side surface 1a of the floor board 1. The sticking at this time is performed by heat welding as described above. Next, the moisture-proof member 4 is attached to the side surface 1 a of the floor board 1. The moisture-proof member 4 is formed by bending a metal foil in advance so as to follow the side surface 1 a including the actual 2, and is attached along the side surface 1 a of the floor board portion 1 including the actual 2. At this time, the peripheral edge 4a of the moisture-proof member 4 is attached to the outer surface of the moisture-proof sheets 31 and 51, and a gap for moisture to enter between the moisture-proof member 4 and the moisture-proof sheets 31 and 51 is generated. This is to prevent this. The moisture-proof member 4 is preferably attached to the side surface 1a of the floor plate portion 1 and the moisture-proof sheets 31 and 51 by a tape such as a double-sided tape. A quick-drying adhesive such as a synthetic rubber adhesive can also be used, but it is not preferable in view of VOC because it contains toluene.
[0022]
By setting it as the above structures, the upper surface moisture-proof layer 3, the moisture-proof layer 5, and the moisture-proof member 4 are stuck on the surface of the floor-plate part 1, and the surface of the floor-plate part 1 is coat | covered with what has moisture-proof property. Therefore, the side surface 1a of the plate member 1 forming the fruit 2 of the moisture-proof member 4 can be prevented from being warped and pushed up due to the floor plate portion 1 absorbing and discharging moisture and expanding and contracting. Adhesion is performed by forming the moisture-proof member 4 in a shape along the side surface 1 a including the fruit 2, so that the moisture-proof member 4 which has been previously retained in the above shape is brought into contact with the side surface 1 a. It is possible to easily and quickly work by simply sticking and sticking, and the moisture-proof treatment can be sufficient.
[0023]
In the present embodiment, the real 2 is formed on the four side surfaces of the floor plate portion 1 in a rectangular shape in plan view, but the real 2 is formed on a part of the four side surfaces, and the side surface on which the real 2 is formed. The moisture-proof member 4 may be attached only to the side surface, and the moisture-proof layer 5 similar to the moisture-proof sheet 51 attached to the lower surface of the floor board portion 1 may be formed on the side surface where the fruit 2 is not formed.
[0024]
