Description
本考案は、集成材に関する。詳しくは、略正方形形状の複数個の板状木片が平面状に配置され、隣り合う板状木片の相対する端面同士が接着されている集成材に関する。 The present invention relates to laminated timber. Specifically, the present invention relates to a laminated material in which a plurality of plate-like pieces of a substantially square shape are arranged in a planar shape and opposite end surfaces of adjacent plate-like pieces of wood are bonded to each other.
従来より、家屋や家具等に幅広く板材が用いられている。板材としては、大径樹木から切り出した比較的大型の無垢材や、複数の薄板材を接着して形成した合板などがある。 Conventionally, plate materials have been widely used for houses and furniture. Examples of the plate material include a relatively large solid material cut out from a large-diameter tree and a plywood formed by bonding a plurality of thin plate materials.
例えば、特許文献1には、「基板に対して,積層薄板を接着剤により接合してなる複合集積材であって,上記積層薄板は,原木をその円周方向に沿って切削することにより第1薄層板を得て,次いで,多数枚の該第1薄層板を接着剤を用いて積層接合することにより積層接合体となし,次いで,該積層接合体をその積層方向に沿った方向に,厚み0.1〜30mmのシートに切断したものであり,かつ該複合集積材は,幅が5〜100cm,長さが30〜400cmであることを特徴とする複合集積材」が記載されており、これによって「表面模様が略同じで,強度に優れ,生産性,施工性に優れた,大形状の複合集積材,及びこれを用いた施工構造を提供することができる。」とある。 For example, Patent Document 1 states that “a composite integrated material obtained by joining laminated thin plates to a substrate with an adhesive, and the laminated thin plates are obtained by cutting a log along its circumferential direction. 1 thin layer plate is obtained, and then a number of the first thin layer plates are laminated and bonded using an adhesive to form a laminated joined body, and then the laminated joined body is oriented along the laminating direction. The composite integrated material is characterized by being cut into a sheet having a thickness of 0.1 to 30 mm and the composite integrated material having a width of 5 to 100 cm and a length of 30 to 400 cm ”. As a result, it is possible to provide a large-sized composite integrated material having substantially the same surface pattern, excellent strength, excellent productivity and workability, and a construction structure using the same. .
しかし近年、急激な天然樹木の減少によって大型の板材を切り出すことが出来るような大径樹木が少なくなり、大型の無垢の板材は高価なものとなっている。無垢の板材は、長期間使用して汚れたような場合であっても、表面を削ればもとの豊かな表情に戻るという優れた特徴を有している。 However, in recent years, large-diameter trees that can cut out large-sized boards due to a sudden decrease in natural trees have decreased, and large-sized solid boards have become expensive. The solid plate material has an excellent feature that even if it is used and soiled for a long time, it will return to its original rich expression if the surface is shaved.
また、木材は方向によって吸水率や収縮率が異なるため、板材に反りや収縮等の変形が生じてしまい、製品価値が低下することがあった。木目が表面に現れるように切り出された板材は、繊維方向には反りにくいものの、これと概ね垂直な方向に反りやすいという欠点がある。十分に乾燥させた木材を用いた場合であっても、吸湿すれば同様であった。 Moreover, since the water absorption rate and the shrinkage rate differ depending on the direction of the wood, the plate material may be deformed such as warping or shrinkage, which may reduce the product value. The plate material cut out so that the grain appears on the surface is not easily warped in the fiber direction, but has a drawback of being easily warped in a direction substantially perpendicular thereto. Even when fully dried wood was used, it was the same if moisture was absorbed.
このような現象は、肉厚の板材(厚板)とした場合に顕著かつ問題となり、例えば、厚板を用いる床材等では乾燥や吸湿による反りが経時的に発生していた。特に、厚板は一旦反ってしまうと、肉厚であるが故、元の状態に戻すことが困難であった。 Such a phenomenon becomes prominent and problematic when a thick plate material (thick plate) is used. For example, a floor material using a thick plate has warped due to drying or moisture absorption over time. In particular, once the thick plate is warped, it is difficult to return to the original state because it is thick.
一方、地球環境の保全の観点などから、リデユース(減らすこと)、リユース(再び使用すること)、及びリサイクル(再資源化すること)という我が国の基本方針(いわゆる3R)に合致した物作りが求められている。 On the other hand, from the viewpoint of global environmental conservation, manufacturing that conforms to Japan's basic policy (so-called 3R) of reuse (reduction), reuse (reuse), and recycling (recycling) is required. It has been.
本考案は、上述の事柄に留意してなされたものであって、反りや収縮等が生じにくく、且つ、無垢材のように、表面を削ればもとの豊かな表情に戻る集成材を提供することを目的とする。 The present invention has been made in consideration of the above-mentioned matters, and provides a laminated material that is unlikely to be warped or contracted, and returns to its original rich expression when the surface is shaved, such as solid wood. The purpose is to do.
上記課題を解決するために、本考案の集成材は、略正方形形状の複数個の板状木片が平面状に配置され、隣り合う板状木片の相対する端面同士が接着されてなる集成材であって、各板状木片の繊維方向が、隣り合う板状木片の繊維方向と概ね直行するように各板状木片が配置された構造とした。ここで、板状木片には、厚みが1〜20cmのものが含まれている。 In order to solve the above-mentioned problems, the laminated material of the present invention is a laminated material in which a plurality of plate-like pieces of a substantially square shape are arranged in a planar shape and opposite end surfaces of adjacent plate-like pieces of wood are bonded together. Thus, each plate-like piece of wood is arranged so that the fiber direction of each piece of plate-like piece is substantially perpendicular to the fiber direction of adjacent plate-like pieces. Here, the plate-like wooden pieces include those having a thickness of 1 to 20 cm.
この集成材は、各板状木片の繊維方向が、隣り合う板状木片の繊維方向と概ね直行するように各板状木片が配置された構造であることにより、各板状木片の反りが抑えられるため、集成材全体としても反りや収縮が生じにくくなる。また、合板とは異なり、長年の使用等によって汚れた場合であっても表面を削ることで、もとの豊かな表情に戻すことができる。さらに、この集成材の表面は、光のあたる方向(見る方向)によって異なる表情を見せ、意匠的にも優れている。加えて、このような優れた特徴により利用用途が広く、例えば、生活用品、建築用品および工芸細工等のあらゆる分野に利用することができる。 This laminated lumber has a structure in which each plate-like wood piece is arranged so that the fiber direction of each plate-like wood piece is substantially perpendicular to the fiber direction of the adjacent plate-like wood piece, thereby suppressing warpage of each plate-like wood piece. Therefore, warpage and shrinkage are less likely to occur as a whole of the laminated material. Also, unlike plywood, even if it becomes dirty due to long-term use, it is possible to restore the original rich expression by shaving the surface. Furthermore, the surface of this laminated material shows a different expression depending on the direction of light (the direction of viewing) and is excellent in design. In addition, due to such excellent features, it can be used in various fields such as daily life, building supplies, and craftwork.
このとき、板状木片が柾目のものである集成材とすることが好ましい。複数個の板状木片の全てが柾目のものであることがより好ましい。 At this time, it is preferable to use a laminated material in which the plate-like piece of wood has a mesh shape. It is more preferable that all of the plurality of plate-like wooden pieces have a mesh shape.
この集成材は、表面に柾目の木目が規則的に並び、とても美しいものである。 This glulam is very beautiful, with regular grain lines on the surface.
またこのとき、複数個の板状木片が、第一の樹木から得られた木材を成形加工したものと、第一の樹木とは異なる種類の第二の樹木から得られた木材を成形加工したものと、からなる集成材とすることも好ましい。 In addition, at this time, a plurality of plate-like pieces of wood molded from wood obtained from the first tree and wood obtained from a second tree of a different type from the first tree. It is also preferable to use a laminated material composed of
この集成材は、第一の樹木と第二の樹木の種類を適宜選択・組み合わせることによって、表面に変化をもたせることができる。例えば、檜から得られた板状木片と、これよりも濃い色調を備えた、桜から得られた板状木片を使用して所望のパターンを描くように配置すれば、表面に幾何学的な模様を形成することができる。 The laminated lumber can be changed in surface by appropriately selecting and combining the types of the first tree and the second tree. For example, if a plate-like piece of wood obtained from a cocoon and a plate-like piece of wood obtained from cherry blossoms with a darker color tone are arranged so as to draw a desired pattern, the surface will have a geometrical shape. A pattern can be formed.
またこのとき、板状木片が廃木材を成形加工したものである集成材とすることも好ましい。複数個の板状木片の全てが廃木材を成形加工したものであることが好ましい。 Further, at this time, it is also preferable to use a laminated material in which the plate-like piece of wood is formed by processing waste wood. It is preferable that all of the plurality of plate-like pieces are formed by processing waste wood.
この集成材は、廃木材をリサイクルして得られたものであり、廃棄物を削減でき地球環境に優しい。 This laminated lumber is obtained by recycling waste wood, which can reduce waste and is friendly to the global environment.
またこのとき、板状木片の厚みが3〜15cmであり、床材として用いられる集成材とすることも好ましい。複数個の板状木片の厚みが全て等しく3〜15cmであることが好ましい。 At this time, the thickness of the plate-like piece of wood is 3 to 15 cm, and it is also preferable to use a laminated material used as a flooring. It is preferable that the thicknesses of the plurality of plate-like pieces are all equal to 3 to 15 cm.
上記本発明の集成材は割れにくいなど強度が強く、また厚板とした場合であっても反りにくい。また、長年の使用等によって汚れた場合であっても表面を削ることで、もとの豊かな表情に戻すことができる。このような優れた特徴を有する本発明の集成材は床材として用いることに最適なのである。 The laminated material of the present invention has high strength such as being hard to break, and even when it is a thick plate, it is difficult to warp. In addition, even if it becomes dirty due to long-term use, it is possible to restore the original rich expression by shaving the surface. The laminated wood of the present invention having such excellent characteristics is optimal for use as a flooring.
本考案により、反りや収縮等が生じにくく、且つ、無垢材のように、表面を削ればもとの豊かな表情に戻る集成材を提供することができる。 According to the present invention, it is possible to provide a laminated material that does not easily warp or contract, and returns to its original rich expression when the surface is cut, such as a solid material.
以下、図を用いて本考案の集成材を例示説明する。 Hereafter, the laminated material of this invention is illustrated and demonstrated using figures.
本考案の集成材は、略正方形形状の複数個の板状木片が平面状に配置され、隣り合う板状木片の相対する端面同士が接着されてなる集成材であって、各板状木片の繊維方向が、隣り合う板状木片の繊維方向と概ね直行するように各板状木片が配置された構成である。 The laminated wood of the present invention is a laminated wood in which a plurality of plate-like wood pieces having a substantially square shape are arranged in a plane, and opposite end faces of adjacent plate-like wood pieces are bonded to each other. Each plate-like piece of wood is arranged so that the fiber direction is substantially perpendicular to the fiber direction of adjacent plate-like pieces of wood.
まず、図1〜図4を用いて、第一実施形態の集成材を説明する。これらの図において、各板状木片の表面には細線で木繊維を描いてある。また、図1において、二十五個の板状木片のうち、一つの板状木片にのみ符号を付してある。なお、以下の実施形態はあくまで本考案を例示説明するものであって、本考案は、以下の具体的な実施形態に限定されるものではない。 First, the laminated material of 1st embodiment is demonstrated using FIGS. 1-4. In these drawings, wood fibers are drawn with fine lines on the surface of each plate-like piece of wood. In FIG. 1, only one plate-like piece of the 25 pieces of plate-like piece is given a reference numeral. The following embodiments are merely illustrative of the present invention, and the present invention is not limited to the following specific embodiments.
[第一実施形態の集成材]
本実施形態の集成材1は、檜材(檜から得られた木材)を成形加工して得られた板状木片2を用いてある。具体的には、乾燥させた檜の端材(廃木材)を、柾目が表面に現れるように、厚み12mmで、55mm角の概ね正方形に切り出して板状木片2を得た。
[Glued material of the first embodiment]
The laminated material 1 of the present embodiment uses a plate-like piece of wood 2 obtained by molding a firewood (wood obtained from firewood). Specifically, the dried wood ends (waste wood) were cut into a roughly square of 55 mm square with a thickness of 12 mm so that squares appeared on the surface, to obtain a plate-like piece of wood 2.
この板状木片2を二十五個用意し、各板状木片2の繊維方向(図1および図8参照)が、隣り合う板状木片2の繊維方向と概ね直行するように各板状木片2を平面状に隙間無く配置しながら、隣り合う板状木片2の相対する端面20同士を接着剤(図示せず)で接着して集成材1を得た。各板状木片2の端面20は平坦なままとし、溝加工等は施さなかった。また、接着剤は環境に優しい水性のものを用いた。 Twenty-five plate-like pieces 2 are prepared, and each piece of piece of wood 2 so that the fiber direction of each piece of piece 2 (see FIGS. 1 and 8) is substantially perpendicular to the fiber direction of the adjacent piece of piece 2 of wood. While arranging 2 in a flat shape without any gaps, opposing end surfaces 20 of adjacent plate-like wooden pieces 2 were adhered to each other with an adhesive (not shown) to obtain laminated material 1. The end face 20 of each plate-like piece 2 was kept flat, and no groove processing or the like was performed. The adhesive used was an environmentally friendly water-based adhesive.
なお、図2及び図3に例示するように、各板状木片2の端面20に各種加工を施してもよい。図2は、隣り合う板状木片2の相対する端面20に、ほぞ21加工とほぞ溝22加工を割り振って施した例である。また、図3は、隣り合う板状木片2の相対する端面20に、各々ダボ穴23加工を施して、ダボ24で連結するようにした例である。これらの加工を施した場合であっても、接着剤を併用することが好ましい。 In addition, as illustrated in FIGS. 2 and 3, various kinds of processing may be performed on the end surface 20 of each plate-like piece 2. FIG. 2 shows an example in which the tenon 21 processing and the tenon groove 22 processing are assigned to the opposing end surfaces 20 of the adjacent plate-like pieces 2. FIG. 3 shows an example in which dowel holes 23 are formed on the opposing end faces 20 of adjacent plate-like pieces 2 and connected by dowels 24. Even when these processes are performed, it is preferable to use an adhesive in combination.
また、図4に示すように、集成材1の外周を枠体5で囲ってもよい。このようにすると集成材1の木口が隠れて更に品位が向上するため、例えば、所望のサイズの集成材を用いることによってテーブルや机の表面板に好適に用いることができる。 Further, as shown in FIG. 4, the outer periphery of the laminated material 1 may be surrounded by a frame body 5.
