Description
本考案は、異なる木材を用いた三層パネルに関し、特に、耐力壁、フローリング、室内間仕切、パーティション、建具素材に好適な高強度、低歪の三層パネルに関する。 The present invention relates to a three-layer panel using different woods, and more particularly to a high-strength, low-distortion three-layer panel suitable for bearing walls, flooring, indoor partitions, partitions, and joinery materials.
従来から存在する集成材は、小さな板を接着剤で貼り合わせ、一定の面積を有する板、場合により柱とした人工木材である。そして、厚みをもたせる場合、適宜複数層を接着し各種の建築場面で用いられている。 Conventionally laminated wood is artificial wood made by sticking a small board with an adhesive and having a certain area, possibly a pillar. And when giving thickness, several layers are adhere | attached suitably and it is used in various construction scenes.
しかしながら、従来の技術では以下の問題点があった。
従来の集成材は、表に表れる意匠を考慮し、同素材（同種の木材）を接着したものであり、複数層を貼り合わせたものについても、基本的に同素材のパネルを接着して厚みを稼いだものであり、無垢材の代替素材、安価な素材という位置づけに過ぎなかった。
However, the conventional technique has the following problems.
Conventional laminated timber is made by bonding the same material (the same kind of wood) in consideration of the design shown in the table, and even for laminated layers, the panel of the same material is basically bonded to the thickness. It was only positioned as an alternative material for solid wood and an inexpensive material.
本考案は上記に鑑みてなされたものであって、歪みの少ない高強度な三層パネルを提供することを目的とする。 The present invention has been made in view of the above, and an object thereof is to provide a high-strength three-layer panel with less distortion.
請求項１に記載の三層パネルは、ともに同厚同素材であるひき板を幅はぎした第一パネルおよび第三パネルを、ひき板向きを同方向にして重ね、その間に、第一パネルおよび第三パネルとは異なる素材である互いに同厚のひき板を幅はぎした第二パネルを、ひき板向きを第一パネルおよび第三パネルに直交して挟み、パネル間を接着したことを特徴とする。 The three-layer panel according to claim 1, wherein the first panel and the third panel, both of which have the same thickness and the same material, are overlapped with each other in the same direction, and the first panel and The second panel is made of a different material from the third panel, and the second panel is stripped with the same thickness. The second panel is sandwiched perpendicularly to the first panel and the third panel, and the panels are bonded. To do.
すなわち、請求項１に係る考案は、ブロック材より縦方向に長尺である幅はぎを用いた直交積層構造により、歪みの少ない高強度な三層パネルを提供できる。また、第一および第三層を同厚としていることにより同一製造ラインを用いることができ生産効率が向上し安価な三層パネルを提供できる。また、中間層である第二層が第一および第三層と異なる素材であるので、接着性や強度性能を向上させることも可能となる。 That is, the device according to claim 1 can provide a high-strength three-layer panel with less distortion by an orthogonal laminated structure using width strips that are longer in the vertical direction than the block material. In addition, since the first and third layers have the same thickness, the same production line can be used, and the production efficiency can be improved and an inexpensive three-layer panel can be provided. Moreover, since the second layer, which is an intermediate layer, is made of a material different from that of the first and third layers, it is possible to improve adhesiveness and strength performance.
ひき板の幅は同一とする必要はないが、概ね同幅とすることにより木調が整う。第一層（または第三層）と第二層の厚みは必ずしも同厚とする必要はないが、同厚とすることにより、第一層（または第三層）と同一製造ラインを用いて第二パネルを製造できて、生産効率を向上させることができ、より安価に三層パネルを提供可能となる。 Although it is not necessary for the widths of the ground plates to be the same, the wood tone is adjusted by making the widths substantially the same. The thicknesses of the first layer (or the third layer) and the second layer are not necessarily the same, but by using the same thickness, the first layer (or the third layer) is used in the same production line. Two panels can be manufactured, production efficiency can be improved, and a three-layer panel can be provided at a lower cost.
請求項２に記載の三層パネルは、請求項１に記載の三層パネルにおいて、第一パネルおよび第三パネルのひき板長さを２５００ｍｍ以上としたことを特徴とする。 The three-layer panel according to claim 2 is characterized in that, in the three-layer panel according to claim 1, the lengths of the first and third panels are 2500 mm or more.
すなわち、請求項２に係る考案は、長尺とすることにより、近年需要のおおきな、天井の高い住宅等に好適な三層パネルを提供することができる。 That is, the invention according to claim 2 can provide a three-layer panel suitable for a house with a high ceiling, which has been in great demand in recent years.
請求項３に記載の三層パネルは、請求項１または２に記載の三層パネルにおいて、素材を、杉、桧、赤松または黒松から選択したことを特徴とする。 The three-layer panel according to claim 3 is the three-layer panel according to claim 1 or 2, wherein the material is selected from cedar, camellia, red pine or black pine.
すなわち、請求項３に係る考案は、同素材の直交積層構造とするより歪みないし狂いの少ない、好適な組合せとして三層パネルを提供することができる。特に、杉や桧は多数植樹されているため、間伐材の利用も促進し、持続的かつ好適な植樹環境の実現に資する。 That is, the invention according to claim 3 can provide a three-layer panel as a suitable combination with less distortion or deviation than a cross-layered structure of the same material. In particular, since many cedars and bushes are planted, the use of thinned wood is also promoted, which contributes to the realization of a sustainable and suitable tree planting environment.
請求項４に記載の三層パネルは、請求項１または２に記載の三層パネルにおいて、第一パネルおよび第三パネルの素材を桧、第二パネルの素材を杉、または、第一パネルおよび第三パネルの素材を杉、第二パネルの素材を桧としたことを特徴とする。 The three-layer panel according to claim 4 is the three-layer panel according to claim 1 or 2, wherein the material of the first panel and the third panel is cocoon, the material of the second panel is cedar, or the first panel and The third panel is made of cedar and the second panel is made of cedar.
すなわち、請求項４に係る考案は、産出間伐材の現状を鑑み、好適な組合せ、かつ、高強度低歪みの三層パネルを提供できる。 That is, the device according to claim 4 can provide a three-layer panel with a suitable combination and high strength and low strain in view of the current state of the thinned wood produced.
本考案によれば、歪みの少ない高強度な三層パネルを提供することができる。 According to the present invention, a high-strength three-layer panel with less distortion can be provided.
以下、本考案の実施の形態を図面を参照しながら詳細に説明する。
ここでは、第一および第三層に桧パネル、中間層である第二層に杉パネルを用いる例を説明する。
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
Here, an example in which a cocoon panel is used for the first and third layers and a cedar panel is used for the second layer, which is an intermediate layer, will be described.
桧材は間伐材を用い、縦３０００ｍｍ、厚み１２ｍｍのひき板を用意し、まず、幅はぎする。すなわち、長辺の側面同士を接着し、第一パネルおよび第三パネルを製作する。このとき、個々のひき板の幅を揃えて全体で４５０ｍｍの幅となるようにしてもよいが、幅はぎした際、幅方向の長さが揃っていない材料を用いる場合は、４５０ｍｍ以上の長さとなるようにして、接着後に４５０ｍｍに切断するようにする。 The thinning is made of thinned wood, and a board with a length of 3000 mm and a thickness of 12 mm is prepared. That is, the long side surfaces are bonded to each other to manufacture the first panel and the third panel. At this time, the widths of the individual strips may be aligned so that the total width is 450 mm. However, when using a material that does not have a uniform length in the width direction when the width is stripped, a length of 450 mm or more is used. Then, after bonding, cut to 450 mm.
杉材も間伐材を用い、縦４５０ｍｍ、厚み１２ｍｍのひき板を用意し、幅はぎして第二パネルを製作する。幅方向は、同様に一定幅のものを接着して３０００ｍｍとしてもよく、不揃いの場合には、３０００ｍｍ以上の長さとし、接着後に３０００ｍｍに切断すればよい。 The cedar is also made of thinned wood, a 450 mm long, 12 mm thick board is prepared, and the second panel is produced by stripping the width. Similarly, the width direction may be 3000 mm by bonding a certain width, and if it is not uniform, the length may be 3000 mm or more, and it may be cut to 3000 mm after bonding.
次いで、第一パネルと第三パネルとの間に縦横を揃えて第二パネルを挟み相互に接着する。これにより直交三層パネルが仕上がる。なお、実際の作業では、三層パネルを多数重ね、上から適宜圧力をかけて圧着するようにする。最後に２５００ｍｍ以上に加工した上で表面を仕上げ加工する。 Next, the second panel is sandwiched between the first panel and the third panel, and the two panels are bonded to each other. Thereby, the orthogonal three-layer panel is finished. In actual work, a large number of three-layer panels are stacked and pressure-bonded by applying appropriate pressure from above. Finally, the surface is finished after processing to 2500 mm or more.
なお、接着剤は集成材接着用であれば特に限定されないが、例えば水性高分子イソシアネート系接着剤を用いることができる。より具体的には、幅はぎには、ピーアイボンド６０００（株式会社オーシカ製）を用いた高周波印加による圧締、積層接着には、ピーアイボンドＴＰ−１１１（同）を用いたコールドプレスによる圧締をおこなう。積層接着に関しては、例えば、接着剤塗布量は３００ｇ／ｍ２、圧締圧力は８ｋｇ／ｃｍ２×１時間とする。 The adhesive is not particularly limited as long as it is used for adhering laminated materials. For example, an aqueous polymer isocyanate-based adhesive can be used. More specifically, the width is clamped by high frequency application using PI Bond 6000 (manufactured by Oshika Co., Ltd.), and the lamination is clamped by cold press using PI Bond TP-111 (same). To do. Regarding the lamination adhesion, for example, the adhesive application amount is 300 g / m 2 and the pressing pressure is 8 kg / cm 2 × 1 hour.
得られた三層パネルは、繊維方向が直交するため、無垢材または単純な集成材に比し、寸法安定性に優れ歪みが少なくなる。また、断面が厚くなるため、保温性や遮音性に優れる。長尺パネルであるので、造作材、家具用材に利用できる。 Since the obtained three-layer panel is orthogonal to the fiber direction, it has excellent dimensional stability and less distortion compared to a solid material or a simple laminated material. Moreover, since the cross section becomes thick, it is excellent in heat retention and sound insulation. Since it is a long panel, it can be used for construction materials and furniture.
特に、第二パネルに杉材を用い、杉材は相対的に密度が小さいため、第一および第三パネルとの接着性が改善され、寸法安定性をより高める。副次的に、密度が小さいことによる比強度の向上にも貢献する。 In particular, cedar is used for the second panel, and the density of the cedar is relatively small. Therefore, the adhesion with the first and third panels is improved, and the dimensional stability is further enhanced. Secondary, it contributes to the improvement of specific strength due to the low density.
なお、上述の三層パネル以外にも、杉−桧−杉、桧−赤松−桧、赤松−桧−赤松、杉−赤松−杉、赤松−杉−赤松、といった三層パネルを製造することもできる。赤松を黒松としてもよい。特に杉と桧は、広範囲に植樹され、間伐材が利用できるので好適である。 In addition to the three-layer panel described above, it is also possible to manufacture three-layer panels such as cedar-bamboo-cedar, cocoon-red pine-wood, red pine-wood-red pine, cedar-red pine-cedar, red pine-cedar-red pine. it can. Red pine may be black pine. In particular, cedars and bushes are suitable because they are planted over a wide area and thinned wood can be used.
＜接着性能評価＞
三層パネルの長期安定性を調べるために、第一層と第三層の間に第二層を挟んで直交接着した試験片を作製し、ＪＡＳ規格およびＡＱ認証試験に則して、浸せき剥離試験および煮沸剥離試験をおこなった。これは、素材の膨潤収縮や熱による接着強度の劣化等を評価する促進試験（加速試験）という位置づけである。
<Adhesion performance evaluation>
In order to investigate the long-term stability of the three-layer panel, a test piece with the second layer sandwiched between the first layer and the third layer and produced by cross-bonding is prepared and immersed in accordance with the JAS standard and AQ certification test. Tests and boiling peel tests were performed. This is positioned as an accelerated test (accelerated test) for evaluating swelling shrinkage of materials, deterioration of adhesive strength due to heat, and the like.
試験片は、杉−杉、桧−杉、赤松−赤松、赤松−杉、の組合せでおこなった（試験片数は各８）。試験概要は、浸せき剥離試験は、水中に２４時間浸せきし、その後７０度で乾燥させて評価したものであり、煮沸剥離試験は、沸騰水中に４時間浸せきし、その後水中浸せきを１時間おこない、最後に７０度で乾燥して評価したものである。 The test pieces were a combination of cedar-cedar, straw-cedar, red pine-red pine, red pine-cedar (number of test pieces: 8 each). The outline of the test is that the immersion peel test was evaluated by immersing in water for 24 hours and then drying at 70 degrees, and the boiling peel test was immersed in boiling water for 4 hours, and then immersed in water for 1 hour. Finally, it was evaluated by drying at 70 degrees.
いずれも浸せき剥離試験は、剥離がほぼ生じず合格であった。一方、煮沸剥離試験はより厳しい環境であったものの、桧−桧に比し、桧−杉の試験片は２０％の合格率の向上、赤松−赤松に比し、赤松−杉の試験片は、約４０％の合格率の向上がみられ、異種素材の組合せの方が、優れた耐久性を示すことが確認できた。 In both cases, the immersion peel test was acceptable with almost no peel. On the other hand, the boiling peel test was a more severe environment, but compared to 桧-桧, 桧 -cedar specimens improved 20%, compared to akamatsu-akamatsu, akamatsu-cedar specimens The pass rate was improved by about 40%, and it was confirmed that the combination of different materials showed superior durability.
また、幅４９０ｍｍ×長さ１９８０ｍｍ×厚み３６ｍｍ（１２ｍｍの３層）の桧−杉−桧の三層パネルと、桧−桧−桧の三層パネルを複数用意し、スパン１８６０ｍｍ、荷重４ｋｇ×５回とした曲げヤング係数測定試験をおこなった。曲げヤング係数は平均値としては９．５〜１０ｋＮ／ｍｍ２であって同等であった。一方、桧の気乾密度は４６０ｋｇ／ｍ３であるのに対し、杉の気乾密度は３００〜４５０ｋｇ／ｍ３であるので、本考案の三層パネルは、曲げ性能を維持しつつ軽量化を図ることができる素材であることが確認できた。 In addition, a plurality of three-layer panels of 桧 -sugi- 桧 and 桧-桧-桧 three-layer panels of width 490 mm × length 1980 mm × thickness 36 mm (3 layers of 12 mm), span 1860 mm, load 4 kg × 5 A bending Young's modulus measurement test was performed. The bending Young's modulus was 9.5 to 10 kN / mm 2 as an average value, which was equivalent. On the other hand, the air-drying density of firewood is 460 kg / m 3 , while the air-drying density of cedar is 300-450 kg / m 3 , so the three-layer panel of the present invention is lightweight while maintaining bending performance. It was confirmed that the material can be used.
本考案である、表面意匠性に優れ、かつ高強度低歪みの三層パネルを用いて、耐力壁、フローリング、間仕切、パーティション、家具、建具（クローゼット、テーブル天板等）といった造作材や家具用材に好適に使用することができる。また、三層構造であるので、断熱扉としても利用できる。
Using this invention's three-layer panel with excellent surface design and high strength and low strain, construction materials and furniture materials such as bearing walls, flooring, partitions, partitions, furniture, fittings (closets, table tops, etc.) Can be suitably used. Moreover, since it has a three-layer structure, it can also be used as a heat insulating door.
