Description

本発明は、建具に関する。   The present invention relates to a joinery.

従来より、縦枠部材と横枠部材からなる芯材の表裏面に表面板を接着して作製される建具が知られている。例えば、本出願人は、ケナフボードの表面に厚みの薄い木質積層板が貼り合わされてなる複合木質板と、この複合木質板が芯材（ドア芯材）として枠組みされたドア芯用枠組み体を提案している（特許文献１）。そして、特許文献１には、一般的なLVL（Laminated Vaneer Lumber:単板積層板）を芯材として使用したドアに比べて、強度物性が高く、芯材の吸湿膨潤に起因して発生する反りが小さいことが記載されている。   DESCRIPTION OF RELATED ART Conventionally, the joinery produced by adhere | attaching a surface plate on the front and back of the core material which consists of a vertical frame member and a horizontal frame member is known. For example, the present applicant has a composite wood board in which a thin wood laminate is bonded to the surface of a kenaf board, and a door core frame body in which the composite wood board is framed as a core material (door core material). (Patent Document 1). Patent Document 1 discloses that warp is caused by high strength physical properties and due to hygroscopic swelling of the core material compared to a door using a general LVL (Laminated Vaneer Lumber) as a core material. Is described as being small.

しかしながら、特許文献１のドア芯用枠組み体の芯材を構成する複合木質板は、比較的高価なケナフボードの表面に木質積層板が貼り合わされて形成されているため、製造されるドア（建具）のコストを抑制することは必ずしも容易ではない。さらに、特許文献１のドア芯用枠組み体に表面板を接着してドア（建具）を形成する場合、表面板と対峙する木質積層板の端部から吸湿が生じる恐れがあり、これによって、ドア（建具）に反りが生じてしまう場合もあると考えられる。特に、縦枠部材の長さが２ｍを超えるような大きな建具の場合に、大きな反りが生じる恐れがあった。   However, the composite wood board constituting the core material of the door core framework of Patent Document 1 is formed by bonding a wood laminate to the surface of a relatively expensive kenaf board. ) Is not always easy to control. Further, when a door (joint) is formed by adhering a surface plate to the door core frame body of Patent Document 1, moisture absorption may occur from the end of the wood laminate facing the surface plate. It is considered that there may be warping in (joint). In particular, in the case of a large joinery in which the length of the vertical frame member exceeds 2 m, there is a possibility that a large warp may occur.

本発明は、以上のとおりの事情に鑑みてなされたものであり、コストを抑制しつつ、芯材の吸湿による反りの発生が確実に抑制された建具を提供することを課題としている。   The present invention has been made in view of the circumstances as described above, and an object of the present invention is to provide a joinery in which generation of warpage due to moisture absorption of the core material is reliably suppressed while cost is suppressed.

上記の課題を解決するために、本発明の建具は、四角柱状の長尺枠部材と、短尺枠部材とを含む芯材の表裏面に表面板が固定されて形成される建具であって、前記長尺枠部材は、表裏面の前記表面板と対峙する側に位置する表層が麻系繊維ボードで形成されており、かつ、前記表層の間にLVLまたはパーティクルボードで形成された芯層が挟持されていることを特徴としている。   In order to solve the above-mentioned problem, the joinery of the present invention is a joinery formed by fixing a surface plate to the front and back surfaces of a core material including a rectangular column-shaped long frame member and a short frame member, In the long frame member, the surface layer located on the side facing the surface plate on the front and back surfaces is formed of hemp fiber board, and the core layer formed of LVL or particle board is formed between the surface layers. It is characterized by being pinched.

この建具では、前記表層の厚みと前記芯層の厚みとの比が、1：1〜1：2.4であることが好ましい。   In this joinery, the ratio between the thickness of the surface layer and the thickness of the core layer is preferably 1: 1 to 1: 2.4.

この建具では、前記長尺枠部材の長さが、240cm〜400cmであることがより好ましい。   In this joinery, the length of the long frame member is more preferably 240 cm to 400 cm.

本発明の建具によれば、コストを抑制しつつ、芯材の吸湿による反りの発生を確実に抑制することできる。   According to the joinery of this invention, generation | occurrence | production of the curvature by moisture absorption of a core material can be suppressed reliably, suppressing cost.

図１は、本発明の建具の一実施形態を例示した分解斜視図である。図２は、図１に示した建具の芯材のＸ部の拡大図である。   FIG. 1 is an exploded perspective view illustrating an embodiment of a joinery of the present invention. FIG. 2 is an enlarged view of a portion X of the core material of the joinery shown in FIG.

建具１は、芯材２の表裏面に表面板３が固定されて形成される。   The joinery 1 is formed by fixing the surface plate 3 to the front and back surfaces of the core material 2.

芯材２は、縦方向に配置された長尺枠部材２１と横方向に配置された短尺枠部材２２とによって縦長の方形状に枠組みされており、その内側に左右の長尺枠部材２１の中央付近を連結する桟材２３が格子状に配設されている。   The core material 2 is framed in a vertically long rectangular shape by a long frame member 21 arranged in the vertical direction and a short frame member 22 arranged in the horizontal direction, and the left and right long frame members 21 are disposed inside the core material 2. Crosspieces 23 connecting the vicinity of the center are arranged in a lattice pattern.

長尺枠部材２１は、四角柱状であり、長手方向（縦方向）長さは160cm〜400cm程度に設計することができる。また、短尺枠部材２２および桟材２３も四角柱状であり、長手方向（横方向）長さは50cm〜150cm程度に設計することができる。   The long frame member 21 has a quadrangular prism shape, and the length in the longitudinal direction (longitudinal direction) can be designed to be about 160 cm to 400 cm. Further, the short frame member 22 and the crosspiece 23 are also in the shape of a quadrangular prism, and the length in the longitudinal direction (lateral direction) can be designed to be about 50 cm to 150 cm.

長尺枠部材２１は、表裏面の表面板３と対峙する側に位置する表層Ｌ１,Ｌ２が麻系繊維ボードで形成されており、かつ、この表層Ｌ１,Ｌ２の間にLVL（Laminated Vaneer Lumber:単板積層板）またはパーティクルボードで形成された芯層Ｍが挟持されている。   In the long frame member 21, the surface layers L1 and L2 located on the side facing the front surface plate 3 on the front and back surfaces are formed of hemp fiber boards, and the LVL (Laminated Vaneer Lumber) is formed between the surface layers L1 and L2. : Single-layer laminated board) or core layer M formed of particle board is sandwiched.

長尺枠部材２１の芯層ＭをLVL（Laminated Vaneer Lumber:単板積層板）で形成する場合、例えば、スギ、カラマツなどの針葉樹やシナ、ブナなどの広葉樹などを原料とした単板が積層されたものを適宜使用することができる。また、長尺枠部材２１の芯層Ｍをパーティクルボードで形成する場合には、解体廃材を樹脂とともに熱圧成形したものなどを適宜使用することができる。   When the core layer M of the long frame member 21 is formed by LVL (Laminated Vaneer Lumber), for example, a single plate made of conifers such as cedar and larch and broad-leaved trees such as China and beech is laminated. What was done can be used suitably. Moreover, when forming the core layer M of the elongate frame member 21 with a particle board, what decomposed | disassembled waste material was hot-press-molded with resin etc. can be used suitably.

LVL（Laminated Vaneer Lumber:単板積層板）およびパーティクルボードは、いずれも比較的安価であるため、建具１のコストを抑制することができる。   Since both LVL (Laminated Vaneer Lumber) and particle board are relatively inexpensive, the cost of the joinery 1 can be suppressed.

長尺枠部材２１の表層Ｌ１,Ｌ２を形成する麻系繊維ボードは、例えば、ケナフ、ジュートなどの麻系繊維を３次元的に絡ませてマット化した麻系繊維に熱硬化性樹脂を含浸させた後、ホットプレスで熱圧成形することにより製造されたものを例示することができる。また、同様の麻系繊維を粒状接着剤と混合したものをマット化した後、ホットプレスで熱圧成形することにより製造されたものを例示することができる。   The hemp fiber board that forms the surface layers L1 and L2 of the long frame member 21 is made by impregnating a thermosetting resin into a hemp fiber that is matted with hemp fibers such as kenaf and jute in three dimensions. Then, what was manufactured by hot-pressing with a hot press can be illustrated. Moreover, what was manufactured by carrying out hot-pressure shaping | molding by hot press after matting what mixed the same hemp fiber with a granular adhesive agent can be illustrated.

麻系繊維の長さは、防湿性、施工性などの観点から、例えば、10〜200nmの範囲を好ましく例示することができる。また、麻系繊維の密度も、防湿性、強度物性などの観点から、500〜1000kg／m3の範囲を好ましく例示することができる。さらに、麻系繊維を固める樹脂としては、コストや強度の観点から、ユリア樹脂、メラミン樹脂、フェノール樹脂などの熱硬化性樹脂を好ましく例示することができる。さらに、樹脂の含有率は、例えば、5〜30重量％、好ましくは15〜25重量％とすることができ、この範囲であることで確実に防湿性を確保することができる。 The length of the hemp fiber can be preferably exemplified, for example, in the range of 10 to 200 nm from the viewpoint of moisture resistance, workability, and the like. Further, the density of the hemp fiber can be preferably exemplified in the range of 500 to 1000 kg / m 3 from the viewpoint of moisture resistance and strength properties. Furthermore, as resin which hardens hemp fiber, thermosetting resins, such as a urea resin, a melamine resin, a phenol resin, can be illustrated preferably from a viewpoint of cost or intensity | strength. Furthermore, the resin content can be, for example, 5 to 30% by weight, preferably 15 to 25% by weight, and moisture resistance can be reliably ensured by being in this range.

そして、長尺枠部材２１は、麻系繊維ボードで形成された表層Ｌ１,Ｌ２の間に、芯層Ｍが挟持されて形成されている。表層Ｌ１,Ｌ２と芯層Ｍは、接着剤で接着されて一体化されていることが好ましい。表層Ｌ１,Ｌ２と芯層Ｍを接着するための接着剤としては、例えば、エチレン酢酸ビニル共重合体、エポキシ樹脂系、ウレタン系の接着剤などを例示することができる。   The long frame member 21 is formed by sandwiching the core layer M between the surface layers L1 and L2 formed of hemp-based fiber board. The surface layers L1 and L2 and the core layer M are preferably bonded and integrated with an adhesive. Examples of the adhesive for bonding the surface layers L1 and L2 and the core layer M include an ethylene vinyl acetate copolymer, an epoxy resin-based adhesive, a urethane-based adhesive, and the like.

表面板３は、縦長の方形状であり、芯材２の大きさ、形状と対応している。表面板３の材料は、例えば、合板、MDF（Medium Density Fiberboard:中密度繊維板）、パーティクルボードなどを例示することができる。表面板３を芯材２に接着するための接着剤としては、例えば、エチレン酢酸ビニル共重合体、エポキシ樹脂系、ウレタン系の接着剤などを例示することができる。なお、接着剤を使用せず、釘や金具を用いて表面板３と芯材２とを固定することもできる。   The surface plate 3 has a vertically long rectangular shape and corresponds to the size and shape of the core material 2. Examples of the material of the surface plate 3 include plywood, MDF (Medium Density Fiberboard), and particle board. Examples of the adhesive for adhering the surface plate 3 to the core material 2 include an ethylene vinyl acetate copolymer, an epoxy resin-based adhesive, and a urethane-based adhesive. The surface plate 3 and the core material 2 can be fixed using a nail or a metal fitting without using an adhesive.

短尺枠部材２２および桟材２３の材料は、無垢材、集成材、LVL（Laminated Vaneer Lumber:単板積層板）、合板、木質繊維板、パーティクルボードなどのうち１種または２種以上を適宜選択することができる。   The material of the short frame member 22 and the crosspiece 23 is appropriately selected from one or more of solid wood, laminated wood, LVL (Laminated Vaneer Lumber), plywood, wood fiberboard, particle board, etc. can do.

従来、建具の反りは、表裏面の環境に温湿度差がある場合に生じると考えられている。特に、木製の芯材が吸湿し、表裏面の環境に温度差が生じると、芯材では冷たい側に含水が移動して厚み方向に含水率の傾斜ができ、この含水率の傾斜によって芯材に反りが生じる。   Conventionally, warping of joinery is considered to occur when there is a temperature and humidity difference between the front and back environments. In particular, if the wooden core material absorbs moisture and a temperature difference occurs between the front and back surfaces, the moisture content of the core material moves to the cold side and the moisture content is inclined in the thickness direction. Warping occurs.

これに対し、図１、２に例示した建具１は、四角柱状の長尺枠部材２１と、短尺枠部材２２とを含む芯材２の表裏面に表面板３が固定されて形成される建具である。そして、本発明の建具１の長尺枠部材２１は、表裏面の表面板３と対峙する側に位置する表層Ｌ１,Ｌ２が麻系繊維ボードで形成されている。さらに、本発明の建具１の長尺枠部材２１は、表層Ｌ１,Ｌ２の間にLVL（Laminated Vaneer Lumber:単板積層板）またはパーティクルボードで形成された芯層Ｍが挟持されている。   On the other hand, the joinery 1 illustrated in FIGS. 1 and 2 is a joinery formed by fixing the surface plate 3 on the front and back surfaces of the core member 2 including the rectangular columnar long frame member 21 and the short frame member 22. It is. And as for the elongate frame member 21 of the fitting 1 of this invention, the surface layers L1 and L2 located in the side which opposes the surface plate 3 of front and back are formed with the hemp fiber board. Further, in the long frame member 21 of the joinery 1 of the present invention, a core layer M formed of LVL (Laminated Vaneer Lumber) or particle board is sandwiched between the surface layers L1 and L2.

このため、建具１は、表層Ｌ１,Ｌ２の麻系繊維ボードの優れた曲げ剛性によって長尺枠部材２１の吸湿による曲がりが抑制され、建具１の反りの発生が確実に抑制される。すなわち、長尺枠部材２１は、表面板３と対峙する側に位置する表層Ｌ１,Ｌ２が麻系繊維ボードで形成されているため、表裏面の環境に温湿度差が生じた場合であっても、麻系繊維ボードが曲がりを抑制し、建具の１の反りの発生が確実に抑制される。そのため、長尺枠部材２１の長さが240cm〜400cmと大きな場合であっても、建具１の反りが生じ難く、様々な用途、設置場所に対応した建具１とすることができる。   For this reason, in the joinery 1, bending due to moisture absorption of the long frame member 21 is suppressed by the excellent bending rigidity of the hemp fiber boards of the surface layers L1 and L2, and the warpage of the joinery 1 is surely suppressed. That is, the long frame member 21 is a case where the surface layers L1 and L2 located on the side facing the front surface plate 3 are formed of hemp fiber board, so that a temperature and humidity difference occurs in the environment of the front and back surfaces. However, the hemp fiber board suppresses the bending, and the occurrence of 1 warp of the joinery is reliably suppressed. Therefore, even if the length of the long frame member 21 is as large as 240 cm to 400 cm, it is difficult for the joinery 1 to be warped, and the joinery 1 corresponding to various uses and installation locations can be obtained.

そして、図２に例示したように、表層Ｌ１の厚みＤ１と表層Ｌ２の厚みＤ２を足した厚み（Ｄ１＋Ｄ２）と、芯層Ｍの厚みＥとの比は、1：1〜1：2.4であることが好ましい。表層Ｌ１の厚みＤ１と表層Ｌ２の厚みＤ２を足した厚み（Ｄ１＋Ｄ２）と芯層Ｍの厚みＥの比がこの範囲であると、コストを抑制しつつ、芯材の吸湿による反りの発生を確実に抑制することができる。実際的には、例えば、表層Ｌ１の厚みＤ１と表層Ｌ２の厚みＤ２を足した厚み（Ｄ１＋Ｄ２）としては4.0〜5.0mm程度、芯層Ｍの厚みとしては8〜24mm程度の範囲を例示することができる。   As illustrated in FIG. 2, the ratio of the thickness D1 of the surface layer L1 and the thickness D2 of the surface layer L2 (D1 + D2) to the thickness E of the core layer M is 1: 1 to 1: 2.4. It is preferable. When the ratio of the thickness D1 of the surface layer L1 and the thickness D2 of the surface layer L2 (D1 + D2) to the thickness E of the core layer M is within this range, the warpage due to moisture absorption of the core material is surely suppressed while the cost is suppressed. Can be suppressed. Actually, for example, the thickness (D1 + D2) of the thickness D1 of the surface layer L1 and the thickness D2 of the surface layer L2 (D1 + D2) is about 4.0 to 5.0 mm, and the thickness of the core layer M is about 8 to 24 mm. Can do.

さらに、表層Ｌ１,Ｌ２の厚みは互いに略等しいことが好ましい。これによって、仮に芯層Ｍへの吸湿が生じた場合にも、表裏面で含水率の偏りが生じ難いため、反りの発生をさらに抑制することができる。   Furthermore, it is preferable that the thicknesses of the surface layers L1 and L2 are substantially equal to each other. Accordingly, even when moisture absorption to the core layer M occurs, it is difficult for the moisture content to be biased between the front and back surfaces, so that the occurrence of warpage can be further suppressed.

本発明の建具は、以上の形態に限定されることはない。例えば、芯材は、縦桟材などを含むこともできる。   The joinery of the present invention is not limited to the above form. For example, the core material may include a vertical beam.
