Description
本発明は、家具や建築材(建具や柱等)のコア材、荷物運搬用のパレット等として利用することができる構造体に関する。 The present invention relates to a structure that can be used as a core material for furniture and building materials (such as joinery and pillars), a pallet for carrying goods, and the like.
家具や建具には見えない部分に紙質(ダンボール)を使用して、強度や物性(反り曲がりの矯正など)を向上させているものがある。代表的なものとして、紙製のハニカムコアを面材でサンドイッチした構造をもつ、フラッシュパネルが挙げられる。しかし、紙製のコアは、それ自体としても、製品化後も、強度、反り、表面接着強度についてきわめて重篤な欠点が発生しやすい。例を挙げると、紙製のコアを用いたフラッシュパネルでは、コア材が薄いため、コア材と面材の接着面積が少なく、接着力不足のため、はく離しやすい。したがって、面材のひずみを十分に吸収できない。また、コア材が薄くて軽く、十分な強度を有していないため、面材が変位(反り曲がり等)したときに、フラッシュパネル自体に反り曲がりが発生する、などといった問題が存在する。 Some papers (cardboard) are used for parts that cannot be seen in furniture and joinery to improve strength and physical properties (such as correction of warping and bending). A typical example is a flash panel having a structure in which a paper honeycomb core is sandwiched between face materials. However, the paper core itself and the product are likely to have serious defects in strength, warpage, and surface adhesion strength. For example, in a flash panel using a paper core, since the core material is thin, the bonding area between the core material and the face material is small, and the adhesive force is insufficient. Therefore, the distortion of the face material cannot be sufficiently absorbed. Further, since the core material is thin and light and does not have sufficient strength, there is a problem that when the face material is displaced (warped or bent), the flash panel itself is warped.
このような問題を解決するため、強度に優れるとともに、面材を十分に補強することができる構造体を提供することを目的として、本発明者は特許文献1にかかる構造体を発明した。
特許文献1の発明によれば、紙製のハニカムコアと比べて強度が高く、また、フラッシュパネルのコア材として用いた場合、面材との接着強度も高いため、面材を十分に補強することができる。さらに、伸縮するため、保管や持ち運びに便利であり、コア材として使用する際には、面材のサイズに合わせてサイズ調整ができるという効果が得られる。
In order to solve such a problem, the present inventor invented the structure according to Patent Document 1 for the purpose of providing a structure that has excellent strength and can sufficiently reinforce the face material.
According to the invention of Patent Document 1, the strength is higher than that of a paper-made honeycomb core, and when used as a core material of a flash panel, since the adhesive strength with the face material is also high, the face material is sufficiently reinforced. be able to. Furthermore, since it expands and contracts, it is convenient for storage and carrying, and when used as a core material, the effect that the size can be adjusted according to the size of the face material is obtained.
しかし、特許文献1の構造体は、溝加工に手間がかかるという問題があり、また、フレキシブルシートが必要であるため、両面に化粧紙等が貼付されている面材(いわゆる化粧板)を利用する場合はよいが、シートが貼付されていない板を利用する場合には、あらためてフレキシブルシートを貼付する手間がかかり、化粧板以外の廃材の有効利用には資さない。 However, the structure of Patent Document 1 has a problem that it takes time to process the groove, and since a flexible sheet is required, a face material (so-called decorative board) in which decorative paper or the like is pasted on both sides is used. However, when using a board without a sheet attached, it takes time to apply a flexible sheet again, and does not contribute to the effective use of waste materials other than the decorative board.
また、特許文献1の構造体は、平面内では自由自在な形に対応できる反面、折曲用溝が板基材の強度を部分的に遮断してしまうという問題があり、さらに、曲面状に湾曲させようとした場合は、折曲用溝の両側をつなぐフレキシブルシートが破断して、板基材が溝部分で分断するため、ソファーの背もたれ部や円柱のような曲面的な家具や建築材のコア材として利用することができないという問題があった。 In addition, the structure of Patent Document 1 can correspond to a free shape in the plane, but has a problem that the bending groove partially blocks the strength of the plate base material, and further has a curved shape. If you try to bend it, the flexible sheet that connects both sides of the groove for bending breaks, and the base plate is divided at the groove. There was a problem that it could not be used as a core material.
本発明は、上述した問題を解決するため、強度および取り扱い性に優れるとともに、溝加工等の手間がかからず、平面形状にも曲面形状にも対応できる構造体を提供することを課題とする。 In order to solve the above-described problems, an object of the present invention is to provide a structure that is excellent in strength and handleability, does not require labor for grooving, and can handle both a planar shape and a curved surface shape. .
本発明者は、上記課題を解決するため、検討を繰り返した結果、剛性の高い板材からなる構造体でありながら、平面上での伸縮が可能であるとともに、曲面に沿って湾曲することが可能な構造体を提供することに成功し、本発明を完成した。 As a result of repeated studies to solve the above-mentioned problems, the present inventor is capable of expanding and contracting on a plane and bending along a curved surface while being a structure made of a highly rigid plate. The present invention was completed by successfully providing a simple structure.
上記課題を解決するために、本発明にかかる構造体は以下の構成を有する。
帯状の板基材を、板面同士を対向させて多数積層してなる構造体であって、
積層最上端および最下端の板基材を除いて、前記板基材はそれぞれ、他の板基材と接着されていない非接着部を介して、その上下に積層された板基材と上下交互に接着されており、且つ、当該接着部は、少なくとも、上下いずれかの板基材との間に2箇所以上設けられていること、
前記板基材の長手方向沿いの一縁または両縁に、切り欠きが形成されていること、
前記切り欠きが各板基材において同じ位置に形成されており、且つ、前記接着部に形成されていること、
前記構造体を積層方向に引き伸ばした際、隣接する2枚の板基材間に、上辺および下辺が当該2枚の板基材からなる紡錘状のセルが開口すること
を特徴とする。
In order to solve the above problems, the structure according to the present invention has the following configuration.
It is a structure formed by laminating a number of strip-shaped plate base materials with the plate surfaces facing each other,
Except for the uppermost and lowermost plate base materials, the plate base materials are alternately turned up and down with plate base materials stacked on the top and bottom via non-adhesive parts that are not bonded to other plate base materials. is bonded to, and, the adhesive portion is at least that provided at two or more locations between the upper or lower plate substrate,
Notches are formed on one edge or both edges along the longitudinal direction of the plate base material,
The notch is formed in the same position in each plate base material, and is formed in the adhesive portion;
When the structure is stretched in the stacking direction, a spindle-shaped cell having an upper side and a lower side made of the two plate bases opens between two adjacent plate bases.
上記構造体は、非伸展時には、薄板が積層された状態そのままであるため、非常にコンパクトである。そして、上記構造体の各板基材は、他の板基材と接着されていない非接着部を介して、その上下に積層された板基材と上下交互に接着されており、且つ、当該接着部は、少なくとも、上下いずれかの板基材との間に2箇所以上設けられているため、上記構造体を積層方向に引っ張ると、隣接する2枚の板基材間に、上辺と下辺が当該2枚の板基材からなる紡錘形のセルが複数出現し、積層方向に伸展する(図1および図2参照)。
ここで、積層最上端・最下端以外の板基材において、当該板基材の上または下に積層された一方の板基材との接着部が2箇所で、他方の板基材との接着部が1箇所であるときは、積層方向に1列のセル群が出現し、上下両方の板基材との接着部が2箇所の場合は、積層方向に2列のセル群が出現する。同様に、上または下に積層された一方の板基材との接着部が3箇所で、他方の板基材との接着部が2箇所または3箇所であるときは、3列または4列のセル群が出現する。一列を構成するセル数は、板基材の枚数を2で割った数か、あるいはその数から1を引いた数となる。
好ましい構造体では、前記接着部は、少なくとも、上下いずれかの板基材との間に3箇所以上存在する。
The structure is very compact because it remains in a state where thin plates are laminated when it is not extended. And each board base material of the above-mentioned structure is pasted up and down alternately with the board base material laminated on the upper and lower sides via the non-adhesion part which is not pasted up with other board base materials, and Since the adhesive portion is provided at least two places between the upper and lower plate base materials, when the structure is pulled in the stacking direction, the upper side and the lower side between the two adjacent plate base materials However, a plurality of spindle-shaped cells composed of the two plate base materials appear and extend in the stacking direction (see FIGS. 1 and 2).
Here, in the plate base materials other than the uppermost layer and the lowermost layer, there are two bonding portions with one plate base material laminated on or under the plate base material, and the other base material is bonded. When the number of parts is one, one row of cell groups appears in the stacking direction, and when there are two bonding portions with both the upper and lower plate bases, two rows of cell groups appear in the stacking direction. Similarly, when there are three adhesion portions with one plate base material laminated on the top or bottom and two or three adhesion portions with the other plate base material, three rows or four rows A group of cells appears. The number of cells constituting one row is the number obtained by dividing the number of plate base materials by 2 or the number obtained by subtracting 1 from the number.
In a preferred structure, there are at least three bonding portions between the upper and lower plate bases.
従来の紙製のハニカム構造体(引き伸ばすと六角形のセルが出現する)には折り目が設けられており、また、特許文献1の構造体にも板面に折曲用溝が設けられており、いずれも直線で囲まれたセルが出現するように構成されている。このように折り目や溝を設ければ、材質が本来持つ強度を部分的に遮断してしまうという問題がある。これに対し、本発明にかかる構造体では、板基材を折り曲げるための溝等が構成されていないため、曲線で囲まれたセルが出現する。すなわち、本発明品は、板基材自体の強度を殺さず使用するため、特許文献1の構造体よりも曲げに対しての強度は向上する。また、開いた状態では材自体に応力がかかる為、それに抵抗する力が常にかかっており、更に曲げ強度が向上する。
また、特許文献1の構造体のように、折曲用溝やフレキシブルシート等を設ける必要がなく、板基材の接着のみで製造できるため、製造が簡単であり、低コストでの生産、量産が可能である。例えば、4m×2mサイズの面材に接着剤を一定幅で塗布後、面材を積層していき、プレス機でプレスして接着した後、所望の幅にカットすることにより、長さ4m(または2m)×幅数cmの板基材からなる構造体を多数製造することができる。このように長さのある構造体を製造できることにより、曲がりに対する強度を維持したフラッシュパネル等を製造する事ができる。
The conventional paper honeycomb structure (hexagonal cells appear when stretched) is provided with folds, and the structure of Patent Document 1 is also provided with a groove for bending on the plate surface. In both cases, cells surrounded by straight lines appear. If folds and grooves are provided in this way, there is a problem that the strength inherent in the material is partially blocked. On the other hand, in the structure according to the present invention, since a groove or the like for bending the plate base material is not configured, a cell surrounded by a curve appears. That is, since the product of the present invention is used without damaging the strength of the plate base material itself, the strength against bending is improved as compared with the structure of Patent Document 1. Moreover, since stress is applied to the material itself in the open state, a resistance force is always applied, and the bending strength is further improved.
Further, unlike the structure of Patent Document 1, it is not necessary to provide a bending groove, a flexible sheet, or the like, and it can be manufactured only by bonding the plate base material. Therefore, the manufacturing is simple, low-cost production, and mass production. Is possible. For example, after applying adhesive to a 4 m x 2 m size face material with a certain width, laminating the face material, pressing and bonding with a press machine, and then cutting to a desired width, the length 4 m ( Alternatively, a large number of structures made of a plate substrate having a size of 2 m) × several cm can be produced. Since a structure having a long length can be manufactured in this manner, a flash panel or the like that maintains strength against bending can be manufactured.
また、上記構造体は、曲面をなすように湾曲させることもできる。すなわち、構造体の積層最上端と最下端の板基材をつかんで、積層方向に対し反り返るように力をかけると、上記構造体は円弧状の曲面をなすように湾曲する(図3参照)。板基材を積層方向へ引き伸ばしながら湾曲させることにより、半径の小さな円弧にも、大きな円弧にも対応可能である。また、最上端と最下端の板基材が接触するまで湾曲させて円柱状の形とすることも可能であり、さらに、円弧の一部の形状とすることや、S字状に屈曲させること、一部のみ曲面形状とすることも可能であるため、様々な曲面形状に対応できる。 Further, the structure can be curved so as to form a curved surface. That is, when the plate body at the uppermost end and the lowermost end of the laminated structure is grasped and a force is applied to warp in the lamination direction, the structure is curved to form an arcuate curved surface (see FIG. 3). . By curving the plate substrate while stretching it in the laminating direction, it is possible to deal with both small and large arcs. It is also possible to make a cylindrical shape by curving until the uppermost and lowermost plate substrates come into contact with each other, and further to form a partial arc shape or bend into an S shape. Since only a part of the curved surface shape is possible, various curved surface shapes can be handled.
板基材の長手方向における、前記接着部の長さは20mm以上であることが好ましい。また、前記セルの上辺および下辺の長さ(以下、セルの一辺の長さとも称する)は、前記接着部の長さの3倍以上であることが好ましく、4倍以上であることがより好ましい。
セルの一辺の長さが上記より短すぎる場合は、セルの開口高さ(積層方向におけるセルの内径の最大値)の上限が小さくなるため、十分な変形を達成できない。
The length of the adhesive portion in the longitudinal direction of the plate substrate is preferably 20 mm or more. Further, the length of the upper side and the lower side of the cell (hereinafter also referred to as the length of one side of the cell) is preferably 3 times or more, more preferably 4 times or more of the length of the adhesive portion. .
When the length of one side of the cell is too shorter than the above, the upper limit of the cell opening height (maximum value of the inner diameter of the cell in the stacking direction) becomes small, so that sufficient deformation cannot be achieved.
本発明にかかる構造体は、積層方向に引き伸ばした場合(すなわち、平面内で伸展させた場合)にも、積層方向に反り返らせた場合(すなわち、曲面をなすように伸展させた場合)にもセルがほぼ均一に出現するため、強度が偏りにくい。
そして、セルが開いた状態で、各セル内に桟木の役目を果たす材を入れることにより、変形状態を維持することができる。このような固定具としては、剛性を有する板状の固定具であって、その長手方向沿いの一縁に所望のピッチでコの字型やU字型の切り欠きが設けられたものが好ましく、この固定具を、構造体の板基材と直交する向きに配置し、切り欠きに板基材を嵌め込むことにより、セルが開いた状態で構造体を固定することができる。この際、平面での変形を保持する場合には、直線状の固定具を用いればよく、曲面での変形を保持する場合には、曲線状の固定具を用いればよい。安定な固定のためには、板基材の接着部を保持することが好ましいため、固定具の切り欠きは、板基材の接着部を嵌め込むのに適したサイズ(すなわち、板基材2枚分を差し込めるサイズ)とすることが好ましい。
また、これに対応して、構造体を構成する板基材の長手方向沿いの一縁に、コの字型やU字型の切り欠きを形成し、且つこの切り欠きを、各板基材の同じ位置に形成すれば、セルが開口した状態で構造体を固定するのに便利である。例えば、上述した固定具として、板基材と同じ板幅の固定具を用い、固定具の切り欠きと、板基材の切り欠きの深さ(板の幅方向における長さ)の合計が、板基材の幅と一致するように両者の切り欠きを形成すれば、固定具と板基材の切り欠きを嵌め合わせることにより、固定具と板基材を完全に同一空間内で組み合わせることができるため、伸展により形成された平面もしくは曲面上での凸凹を生じず固定することが可能である。板基材の切り欠きが深すぎると破損の恐れがあるため、板基材側の切り欠きの深さは、板基材の幅の半分未満とすることが好ましい(より好ましくは板基材の幅の1/5〜2/5程度)。板基材側の切り欠きは、長手方向沿いの両縁に設けてもよいが、この場合は、各縁における切り欠きの位置を異ならせることが好ましい。
また、板基材の切り欠きは、接着部に設けることが好ましい。
When the structure according to the present invention is stretched in the laminating direction (that is, extended in a plane) or warped in the laminating direction (that is, extended so as to form a curved surface). However, since the cells appear almost uniformly, the strength is not biased.
And the state which deform | transformed can be maintained by putting the material which plays the role of a crosspiece in each cell in the state which the cell opened. Such a fixture is preferably a plate-like fixture having rigidity, and a U-shaped notch or U-shaped notch is provided at a desired pitch on one edge along the longitudinal direction. The structure can be fixed in a state where the cells are opened by disposing the fixing tool in a direction orthogonal to the plate substrate of the structure and fitting the plate substrate into the notch. At this time, a linear fixture may be used to hold the deformation on the plane, and a curved fixture may be used to hold the deformation on the curved surface. Since it is preferable to hold the adhesive part of the plate base material for stable fixation, the notch of the fixing tool is a size suitable for fitting the adhesive part of the plate base material (that is, the base material 2). It is preferable to use a size that allows insertion of sheets.
Correspondingly, a U-shaped or U-shaped notch is formed at one edge along the longitudinal direction of the plate base material constituting the structure, and this notch is formed on each plate base material. If they are formed at the same position, it is convenient to fix the structure with the cells open. For example, as a fixture described above, using a fixture having the same plate width as the plate base material, the total of the notch of the fixture and the notch depth of the plate base material (length in the width direction of the plate) If the notches of both are formed to match the width of the plate base material, the fixture and plate base material can be combined completely in the same space by fitting the notches of the fixture and plate base material together. Therefore, it is possible to fix without causing unevenness on a flat surface or curved surface formed by extension. If the notch of the plate base is too deep, there is a risk of breakage. Therefore, the depth of the notch on the side of the plate base is preferably less than half the width of the plate base (more preferably the plate base 1/5 to 2/5 of the width). The notches on the plate substrate side may be provided on both edges along the longitudinal direction, but in this case, the positions of the notches on each edge are preferably different.
Moreover, it is preferable to provide the notch of a board | substrate base material in an adhesion part.
好適な構造体の例として、厚み1〜5mmの板基材からなり、接着部の長さが20〜80mmであり、セルの一辺の長さが200〜800mmであって、且つ、セルの一辺の長さが前記接着部の長さの4倍以上である構造体を挙げることができる。 As an example of a suitable structure, it is composed of a plate substrate having a thickness of 1 to 5 mm, the length of the adhesive portion is 20 to 80 mm, the length of one side of the cell is 200 to 800 mm, and one side of the cell The structure whose length is 4 times or more of the length of the said adhesion part can be mentioned.
本発明の構造体は、平面および/または曲面を有する建築材または家具(例えば、フラッシュパネルや、柱、イスの背もたれ部等)のコア材として用いるのに好適である。この際、面材(表装材)と同じ材質からなる構造体を用いれば、面材との接着が容易である。 The structure of the present invention is suitable for use as a core material of a building material or furniture having a flat surface and / or a curved surface (for example, a flash panel, a pillar, a back portion of a chair, etc.). At this time, if a structure made of the same material as the face material (surface material) is used, adhesion to the face material is easy.
また、本発明の構造体は荷物運搬用のパレットとして使用するのに好適である。パレットとして使用する場合の好ましい例として、幅100〜200mmの板基材を用い(材質としては、塩化ビニル等の合成樹脂が好ましい)、積層方向の一端側から少なくとも半数(より好ましくは2/3以上)の板基材の板面に、フォークリフトのフォークを挿通するための孔を連続して設けた構造体が挙げられる。 The structure of the present invention is suitable for use as a pallet for carrying goods. As a preferable example when used as a pallet, a plate base material having a width of 100 to 200 mm is used (as a material, a synthetic resin such as vinyl chloride is preferable), and at least half (more preferably 2/3) from one end side in the stacking direction. A structure in which holes for inserting a fork of a forklift are continuously provided on the plate surface of the plate base material as described above.
本発明の構造体は、簡易な工程で製造することができる。また、平面内で伸縮させることができるだけでなく、曲面内で伸縮させることができ、伸展させる力の強弱により、所望のサイズに調節できるため、非常に汎用性が高い。非伸展時には板を積層しただけの容量となるため、保管や持ち運びに便利である。また、板基材の材質・厚み・幅の調節により強度の調節ができるため、家具等のコア材としてだけではなく、トン単位の荷物を載せるパレットとして用いることも可能である。 The structure of the present invention can be manufactured by a simple process. In addition to being able to expand and contract within a plane, it can be expanded and contracted within a curved surface, and can be adjusted to a desired size by the strength of the extending force, so it is very versatile. It is convenient for storage and carrying because it has the capacity of just stacking the plates when not extended. In addition, since the strength can be adjusted by adjusting the material, thickness, and width of the plate base material, it can be used not only as a core material for furniture or the like but also as a pallet on which tons of luggage are placed.
本発明の板基材は、力を加えれば撓むが、力を除けばすぐに元の直線形状に戻る程度の剛性と可撓性を有するものであって、且つ、接着可能な材質からなる板基材であればよい。接着には、接着剤による接着だけでなく、溶着も含まれる。
このような板基材の例として、1mm〜5.5mm厚のMDF(中質繊維板)、3mm〜4mm厚のパーティクルボード、1mm〜5mm厚の合板、1mm〜5mm厚の樹脂板(塩化ビニル樹脂、アクリル樹脂等)、1mm〜4mm厚の強化紙、0.5mm厚程度の鉄板、0.3〜1mm厚のアルミ板が挙げられる。板基材の表面が紙や合成樹脂等のシートで被覆されているもの(例えば化粧板)は、伸展時にシート層が剥離するおそれがあるので、表面が被覆されていない板基材を用いることが好ましい。
The plate base material of the present invention bends when a force is applied, but has rigidity and flexibility enough to return to the original linear shape when the force is removed, and is made of a material that can be bonded. Any plate substrate may be used. Bonding includes not only bonding with an adhesive but also welding.
Examples of such plate base materials include 1 mm to 5.5 mm thick MDF (medium fiberboard), 3 mm to 4 mm thick particle board, 1 mm to 5 mm thick plywood, 1 mm to 5 mm thick resin board (vinyl chloride resin) , Acrylic resin, etc.) 1 mm to 4 mm thick reinforced paper, about 0.5 mm thick iron plate, 0.3 to 1 mm thick aluminum plate. If the surface of the board substrate is coated with a sheet of paper or synthetic resin (for example, a decorative board), the sheet layer may be peeled off during extension, so use a board substrate that is not coated with the surface. Is preferred.
板基材同士の接着は、板基材の材質を考慮して、適切な接着剤を使用すればよい。例えば、板基材が合成樹脂や木質材料からなる場合は酢酸ビニル樹脂系接着剤を使用することができる。
また、板基材が金属・合成樹脂からなる場合は、接着剤を用いず、溶接や溶着により接着してもよい。
Adhesion between plate base materials may be performed using an appropriate adhesive in consideration of the material of the plate base material. For example, when the plate substrate is made of a synthetic resin or a wood material, a vinyl acetate resin adhesive can be used.
Further, when the plate substrate is made of a metal / synthetic resin, it may be bonded by welding or welding without using an adhesive.
また、本発明の構造体は、板基材の材質・幅・厚み等を調節することにより、家具等のコア材以外にも、様々な用途に用いることができる。例えば、合成樹脂板(アクリル樹脂板、塩化ビニル樹脂板等)を用いれば、耐候性にも優れるため、外部での使用に好適である。また、強度を高めれば、スノコ、門扉、側溝フタ、シャッター、コンテナ、パレット(荷物をのせたままフォークリフトなどで移動する荷台)として用いるにも適している。 Moreover, the structure of this invention can be used for various uses besides core materials, such as furniture, by adjusting the material, width | variety, thickness, etc. of a board | substrate base material. For example, if a synthetic resin plate (acrylic resin plate, vinyl chloride resin plate, etc.) is used, it is excellent in weather resistance, and thus is suitable for external use. Further, if the strength is increased, it is also suitable for use as a snowboard, gate, gutter lid, shutter, container, pallet (loading platform that moves with a forklift or the like while carrying the load).
板基材の厚みは、金属板(鉄板やアルミ板)の場合は0.3mm以上1mm以下、合成樹脂板や木質材料板の場合は、1mm以上6mm以下が好ましい(より好ましくは2〜4mm)。薄すぎると強度が落ち、他方、分厚すぎると重量が重くなる。 The thickness of the plate substrate is preferably 0.3 mm or more and 1 mm or less in the case of a metal plate (iron plate or aluminum plate), and preferably 1 mm or more and 6 mm or less (more preferably 2 to 4 mm) in the case of a synthetic resin plate or a wood material plate. . If it is too thin, the strength decreases, and if it is too thick, the weight increases.
板基材の板幅は、用途に合わせ(家具のコア材、パレット等)適宜選択すればよい。コア材として用いる場合、幅10〜40mmが一般的であり、25〜35mmが汎用されるサイズである。 The board width of the board substrate may be appropriately selected according to the use (furniture core material, pallet, etc.). When used as a core material, a width of 10 to 40 mm is common, and 25 to 35 mm is a commonly used size.
板基材の長さも、用途に合わせ適宜選択すればよい。例えば、フラッシュパネルのコア材として用いる場合、板基材の長さは650〜2000mmが一般的な範囲である。パレットとして用いる場合は、900〜2000mmが一般的な範囲である。 What is necessary is just to select the length of a board | substrate base material suitably according to a use. For example, when used as a core material of a flash panel, the length of the plate base material is in a general range of 650 to 2000 mm. When used as a pallet, 900 to 2000 mm is a general range.
本発明において、板基材を多数積層したとは、少なくとも板基材を4枚以上積層したことを意味する。8枚以上積層したものがより好ましい。 In the present invention, the fact that a large number of plate substrates are laminated means that at least four plate substrates are laminated. What laminated | stacked 8 or more sheets is more preferable.
接着部の長さ(板基材の長手方向における長さ)は、20mm〜70mm程度が好ましく、30〜60mm程度がより好ましい。接着部が短すぎると剥離しやすくなるため、耐久性の点で問題があり、他方、接着部が長すぎると、伸展率が低下する。また、全ての接着部の長さは等しいことが理想的であるが、接着部ごとに多少相違してもよい。例えば平均50mmの場合、40〜60mmの範囲内(平均値に対し±20%)で相違していても問題なく使用することができる。
セルの一辺の長さは、所望する構造体の伸展率によって適宜変更すればよいが、200〜800mm程度が好ましく、300〜600mm程度がより好ましい。また、セルの一辺の長さは、接着部の長さの4倍以上であることが好ましく、5倍以上であることがより好ましい。セルの一辺の長さは全ての場所で均一であることが理想的であるが、セルごとに多少相違していてもよく、平均値に対し、±15%程度相違していてもよい。
About 20 mm-70 mm are preferable and, as for the length (length in the longitudinal direction of a board | substrate base material) of an adhesion part, about 30-60 mm is more preferable. If the bonded portion is too short, it is easy to peel off, which causes a problem in terms of durability. On the other hand, if the bonded portion is too long, the stretch ratio is lowered. Moreover, although it is ideal that the length of all the adhesion parts is equal, you may differ somewhat for every adhesion part. For example, in the case of an average of 50 mm, even if it is different within a range of 40 to 60 mm (± 20% with respect to the average value), it can be used without any problem.
The length of one side of the cell may be appropriately changed depending on the desired extension of the structure, but is preferably about 200 to 800 mm, and more preferably about 300 to 600 mm. Further, the length of one side of the cell is preferably 4 times or more, and more preferably 5 times or more the length of the bonded portion. Ideally, the length of one side of the cell should be uniform in all places, but it may be slightly different for each cell, and may be about ± 15% different from the average value.
本発明の構造体では、積層最上端および最下端の板基材を除いて、各板基材はそれぞれ、上の板基材と接着している箇所(a)、いずれの板基材とも接着していない箇所(b)、下の板基材と接着している箇所(c)、いずれの板基材とも接着していない箇所(b’)、の繰り返しの中で上下に積層された板基材と連結されるが、この際、bとb’が等しい(すなわち隣り合うa−a間の中点にcが存在する)ことが好ましい。このように構成することにより、中央が最も膨らんだ左右対称の紡錘形のセルが出現するため、強度の偏りやひずみが生じにくくなる。なお、cがa−a間の中点から多少ずれていてもよいが、ずれすぎるとセルが開口しにくくなるため、a−a間の中点からのずれはセルの一辺の長さの1/5以内に納まることが好ましい。
本発明では、接着部は、上下いずれかの板基材との間に2箇所以上設けられていればよい(すなわち、各板基材において、上記(a)または(c)が2箇所以上あればよい)。接着部が、上または下に積層された一方の板基材との間に2箇所、他方の板基材との間に1箇所設けられている場合は、図10に示すように、積層方向に一列の紡錘形状のセル群が開口する。接着部が、上または下に積層された一方の板基材との間に3箇所、他方の板基材との間に2箇所設けられている場合は、図2に示すように、積層方向に3列のセル群が開口する。各列を構成するセル数は、板基材の枚数を2で割った数か、そこから1を引いた数となる。図2の構造体では、22枚の板基材が使用されているため、セル11個からなる列が2列と、セル10個からなる列(中央の列)が1列出現する。
In the structure of the present invention, each plate substrate is bonded to the upper plate substrate (a) except for the uppermost and lowermost plate substrates, and is bonded to any plate substrate. Plates that are stacked up and down in repetition of a portion (b) that is not bonded, a portion (c) that is bonded to the lower plate substrate, and a portion (b ′) that is not bonded to any plate substrate Although it connects with a base material, it is preferable that b and b 'are equal at this time (namely, c exists in the midpoint between adjacent aa). By configuring in this way, a symmetrical spindle-shaped cell with the center swelled most appears, so that strength bias and distortion are less likely to occur. Note that c may be slightly deviated from the midpoint between aa, but if it is too deviated, it becomes difficult for the cell to open. Therefore, the deviation from the midpoint between aa is 1 of the length of one side of the cell. / 5 or less is preferable.
In the present invention, the adhesive portion may be provided at two or more places between the upper and lower plate base materials (that is, each plate base material includes the above (a) or (c) at two or more locations). Just fine). When the adhesive portion is provided at two places between one plate base material laminated on the top or bottom and at one place between the other plate base materials, as shown in FIG. A row of spindle-shaped cells is opened in a row. In the case where the adhesive portion is provided at three places between one plate base material laminated on the top or bottom and at two places between the other plate base material, as shown in FIG. Three rows of cell groups are opened. The number of cells constituting each row is the number obtained by dividing the number of plate base materials by 2 or the number obtained by subtracting 1 from the number. In the structure of FIG. 2, since 22 plate base materials are used, two rows of 11 cells and one row of 10 cells (center row) appear.
以下、実施例により本発明にかかる構造体をより詳細に説明する。 Hereinafter, the structure according to the present invention will be described in more detail by way of examples.
以下の手順により、本発明にかかる構造体を製造した。図1〜3に本実施例の構造体と同様の構造体(板基材の枚数・接着部の数・切り欠き5の有無等は異なる)を示す。
板基材2として、2.5mm厚のMDF(長さ2150mm×幅150mm)を使用した。前記板基材2を8枚用意し、図4示すように、2,4,6,8枚目の板基材の上面の一端側に接着剤(酢酸ビニルエマルジョン系接着剤)を50mm幅で塗布し、さらに、一定の間隔(370mm)を空けて接着剤の塗布(同じく50mm幅)を繰り返した(以下、本実施例において、各板基材において、接着剤を塗布した範囲(50mm幅)を接着部3、接着剤が塗布されていない範囲(370mm幅)をセル辺と称する)。3,5,7枚目の板基材には、偶数枚目の板基材のセル辺の中央に位置するように、同じ間隔・同じ幅にて接着剤を塗布した。8枚の板基材を積層して(接着剤塗布量190g/m2)、冷圧プレス圧5kg/cm2にて40分加圧し、各板基材を接着した。
構造体は、図1(B)に示すとおり、積層最上端および最下端以外の板基材2において、−上の板基材と接着された箇所/いずれの板基材とも接着されない箇所/下の板基材と接着された箇所/いずれの板基材とも接着されない箇所−の四箇所の繰り返しにより、上下の板基材と連結しており、接着部3が、非接着部を介して上下交互に繰り返される構成となっている。
The structure according to the present invention was manufactured by the following procedure. 1 to 3 show a structure similar to the structure of the present embodiment (the number of plate base materials, the number of adhesion portions, the presence or absence of notches 5 and the like are different).
A 2.5 mm thick MDF (length 2150 mm × width 150 mm) was used as the plate substrate 2. Eight plate base materials 2 are prepared. As shown in FIG. 4, an adhesive (vinyl acetate emulsion adhesive) is applied to one end of the top surface of the second, fourth, sixth, and eighth plate bases in a width of 50 mm. The adhesive was further applied at a constant interval (370 mm) (also 50 mm width) (hereinafter, in this example, the area where the adhesive was applied to each plate substrate (50 mm width)) Is a bonding part 3, and a range (370 mm width) where the adhesive is not applied is called a cell side). The adhesive was applied to the third, fifth, and seventh plate base materials at the same interval and the same width so as to be located at the center of the cell side of the even-numbered plate base material. Eight plate base materials were laminated (adhesive coating amount 190 g / m 2 ) and pressed for 40 minutes with a cold press pressure of 5 kg / cm 2 to bond the plate base materials.
As shown in FIG. 1 (B), in the plate substrate 2 other than the uppermost layer and the lowermost layer, the structure is bonded to the upper plate substrate / unbonded to any plate substrate / lower. It is connected to the upper and lower plate bases by repeating the four places of the part bonded to the plate base material / the part that is not bonded to any plate base material, and the bonding part 3 is moved up and down via the non-bonding part. It becomes the structure repeated alternately.
この構造体1を、積層方向に引き伸ばしたところ、図2に示すように、各板基材2間に曲線で囲まれた紡錘形状(中央付近が太く、両端が次第に細くなっている形状)のセル4が多数出現した。各セルの上辺及び下辺は隣接する2枚の板基材からなり、上辺および下辺の長さは370mmである。
各セル4は非常に均等に開口し、また、伸展させる力の度合いにより、セルの開口サイズを調節することが可能であった。
When the structure 1 is stretched in the stacking direction, as shown in FIG. 2, a spindle shape (a shape in which the vicinity of the center is thick and the both ends are gradually narrowed) surrounded by curves between the plate base materials 2 is obtained. Many cells 4 appeared. The upper side and the lower side of each cell are composed of two adjacent plate base materials, and the length of the upper side and the lower side is 370 mm.
Each cell 4 opens very evenly, and the opening size of the cell can be adjusted according to the degree of force of extension.
上記構造体1について、板基材2の幅が25mmとなるように切断した。板基材2の幅が小さくなることにより、構造体1はより小さな力で自在に伸縮できるようになった。 About the said structure 1, it cut | disconnected so that the width | variety of the board | substrate base material 2 might be set to 25 mm. By reducing the width of the plate substrate 2, the structure 1 can be freely expanded and contracted with a smaller force.
図3に、構造体1を曲面状に屈曲させた状態を示す。図3に示すように、積層体の最上端の板基材と最下端の板基材が接近するように、すなわち構造体が積層方向に対して反り返るように力を加えると、各板基材2間に紡錘形状のセルが出現し、構造体1は湾曲する。図3では、半柱状に湾曲させた状態を示したが、より力をかければ完全な円柱状となり、力を弱めればより緩やかな曲面をなす。さらに、板基材の一端側に力をかけて円錐状の形状(あるいは円錐の一部の形状)とすることや、図10に示すように、湾曲方向を途中で変えてS字状の形状とすることも可能である。 FIG. 3 shows a state where the structure 1 is bent into a curved shape. As shown in FIG. 3, when a force is applied so that the uppermost plate base material and the lowermost plate base material of the laminated body approach each other, that is, the structure warps in the stacking direction, A spindle-shaped cell appears between the two, and the structure 1 is curved. Although FIG. 3 shows a state of being curved in a semi-columnar shape, a more cylindrical shape is obtained when more force is applied, and a gentler curved surface is formed when the force is weakened. Furthermore, a conical shape (or a partial shape of the cone) is applied by applying a force to one end side of the plate base material, or an S-shape is formed by changing the bending direction in the middle as shown in FIG. It is also possible.
セル4の開口面積は、伸展させる力の強弱によって調節可能であるため、使用時にセル4の開口程度を適宜調節することにより、構造体1を所望のサイズに調節できる。 Since the opening area of the cell 4 can be adjusted by the strength of the extending force, the structure 1 can be adjusted to a desired size by appropriately adjusting the opening degree of the cell 4 during use.
セル4の一辺の長さおよび接着部3の長さは、構造体の製造時に決まるため、使用する用途に合わせ適宜調節すればよい。セルの一辺の長さを大きくすれば、開口時のセル面積の上限が大きくなるため、より伸展率の高い構造体とすることができ、他方、セルの一辺の長さを短くすれば、板基材の密度が高く、強度に優れた構造体とすることができる。接着部の長さは、セルの一辺の長さもしくは構造体にかかる力を考慮し、十分な接着強度を有する長さとすればよい。これは板基材の剛性、材質、所望する接着強度等によって変わるため、適宜調節すればよい。 Since the length of one side of the cell 4 and the length of the bonding portion 3 are determined at the time of manufacturing the structure, they may be appropriately adjusted according to the intended use. If the length of one side of the cell is increased, the upper limit of the cell area at the time of opening is increased, so that a structure with a higher extension rate can be obtained. On the other hand, if the length of one side of the cell is shortened, the plate A substrate having a high density and excellent strength can be obtained. The length of the adhesive portion may be a length having sufficient adhesive strength in consideration of the length of one side of the cell or the force applied to the structure. Since this varies depending on the rigidity, material, desired adhesive strength, etc. of the plate base material, it may be adjusted as appropriate.
2.5mm厚のMDFを用いて、長さ2150mm・幅25mmの板基材16枚からなる構造体を作成した。板基材の枚数以外は、実施例1と同じ構成である。その後、フラッシュドア用の枠体(枠体の内径サイズ:高さ2030mm、幅780mm、枠体厚み25m)内に、板基材がドアの高さ方向と平行になるように構造体を納め、構造体の最上端と最下端の板基材が枠体の縦芯に達するまで構造体を引き伸ばし、最上端と最下端の板基材と枠体の縦芯とを接着した(図8参照;板基材の枚数や接着箇所は本実施例の構造体と異なる)。縦芯との接着は、板基材間の接着パターンと同じとなるように行った。なお、枠体の高さ2030mmに対し、板基材の長さは2150mmであるが、積層方向に引き伸ばした際は、板基材が波打つように変形するため、問題なく構造体を枠体内に納めることができた。
積層方向に9列のセル群が出現し、各列におけるセル数は8個または7個であった。各セルはほぼ均等であり、各セルの開口高さ(積層方向におけるセル内径の最大値)は約93mmとなった。しかし、元の積層状態に戻ろうとする力が大きいため、枠体の縦芯が内側に若干撓んでしまい、後工程の縦芯のカット(均等3mmの切り落し)が困難な状態となった。
各セルの開口を小さくして、元の積層状態に戻ろうとする力を弱めるために、板基材の枚数を28枚に増やした構造体を作成した。上記と同様に枠体内に固定したところ、各セルの開口高さは約50mmとなった。この結果、縦芯の剛性が構造体の収縮力を上回り、今回は縦芯に撓みが生じず、後工程の縦芯カットを行うことができた。
Using a 2.5 mm thick MDF, a structure composed of 16 plate base materials having a length of 2150 mm and a width of 25 mm was prepared. The configuration is the same as that of Example 1 except for the number of plate base materials. After that, put the structure in the frame for flash door (frame inner diameter size: height 2030mm, width 780mm, frame thickness 25m) so that the plate base material is parallel to the height direction of the door, The structure was stretched until the uppermost end and the lowermost plate base material of the structure reached the vertical core of the frame, and the uppermost and lowermost plate base materials and the vertical core of the frame were bonded (see FIG. 8; The number of plate base materials and the bonding location are different from the structure of this embodiment). Adhesion with the vertical core was performed so as to be the same as the adhesion pattern between the plate substrates. Note that the length of the plate base material is 2150 mm compared to the frame height of 2030 mm, but when stretched in the stacking direction, the plate base material deforms so as to wave, so the structure can be put into the frame without any problem. I was able to pay.
Nine rows of cell groups appeared in the stacking direction, and the number of cells in each row was 8 or 7. Each cell was almost uniform, and the opening height of each cell (the maximum value of the cell inner diameter in the stacking direction) was about 93 mm. However, since the force to return to the original laminated state is large, the vertical core of the frame body is slightly bent inward, and it becomes difficult to cut the vertical core in the subsequent process (equal 3 mm cut-off).
In order to make the opening of each cell small and weaken the force to return to the original laminated state, a structure in which the number of plate bases was increased to 28 was created. When fixed in the frame as above, the opening height of each cell was about 50 mm. As a result, the rigidity of the vertical core exceeded the contraction force of the structure. This time, the vertical core did not bend, and the vertical core cut in the subsequent process could be performed.
軽量化を図る為に、2.5mm厚のMDFの代わりに、1mm厚のMDFを用いた他は、上記実施例と同様にして、板基材28枚からなる同じ構成の構造体を製造した。
1mm厚のMDFは、2.5mm厚のMDFと比較して強度が弱いため、2枚の板基材間の非接着長さ(セルの一辺の長さ)が370mmでは、本実施例のドアのコア材としては、硬度が不十分であった(最上端と最下端の板基材をドア用枠体の縦芯に固定した状態で、ドア用枠体を直立させると、中央部に撓みが生じて自立できず倒れた)。
そのため、セルの一辺の長さを200mmとしたところ、セルは非常にきれいに均等に開き、硬度の点でも問題なかった。各セルの開口高さは約55mmであった。
しかし、1mmのMDFに対して、セルの開口高さが55mmでは、圧に対して剛性がやや弱いと思われたため、板基材の枚数を36枚にし、セルの開口高さが約40mmとなるようにした。この結果、圧に対する十分な剛性が得られた。
In order to reduce the weight, a structure having the same structure composed of 28 plate base materials was manufactured in the same manner as in the above example except that 1 mm thick MDF was used instead of 2.5 mm thick MDF.
Since the 1 mm thick MDF is weaker than the 2.5 mm thick MDF, the non-adhesive length between two plate bases (the length of one side of the cell) is 370 mm. As the core material, the hardness was insufficient. (When the uppermost and lowermost plate bases are fixed to the vertical core of the door frame, if the door frame is made upright, the center part will be bent. It occurred and I couldn't stand up and fell down).
For this reason, when the length of one side of the cell was set to 200 mm, the cell opened very neatly and had no problem in terms of hardness. The opening height of each cell was about 55 mm.
However, when the cell opening height was 55 mm for 1 mm MDF, the rigidity was somewhat weak against pressure, so the number of plate substrates was 36, and the cell opening height was about 40 mm. It was made to become. As a result, sufficient rigidity against pressure was obtained.
このように、板基材の厚み・枚数・セルの一辺の長さ等を変更するにより、強度や剛性の異なる構造体が作成できるため、所望の強度・剛性の構造体となるよう、各ファクターを適宜調節して、様々な構造体を得ることができる。 In this way, structures with different strength and rigidity can be created by changing the thickness, number of sheets, the length of one side of the cell, etc. As appropriate, various structures can be obtained.
試作を繰り返した結果、最上端と最下端の板基材を枠体に接着するのみの構成(図8参照)では、各セルの形状が不均一になる場合があるため、各セルの開口状態を一定に調節でき、構造体を伸展状態で保持することができる固定具の開発を試みた。
実施例2で製造した、2.5mm厚の板基材(MDF)・28枚からなる構造体を固定するための固定具を作成した。固定具としては、2.5mm厚のMDFからなる板であって、長さ約780mm・幅25mmの板を用い、その長手方向沿いの一縁に、溝幅(板の長さ方向における長さ)約5mm・溝深さ(板の幅方向における長さ)約15mmのコの字型の溝(切り欠き)を、約55mmのピッチで15箇所設けた。固定具の両端だけはL字型に切り欠き、固定具の両端を枠体の縦芯に接着した際に、枠体の壁面との間でコの字型の溝ができるように構成した。
他方、構造体の板基材の長手方向沿いの一縁には、二枚の板基材が接着している箇所の中央部に、溝幅約2.5mm・溝深さ約10mmのコの字型の溝(切り欠き)を入れた。切り欠きは、全ての接着部ではなく、長手方向に一つ飛ばしで設けた。この固定具を板基材と直交に配置して、双方の切り欠きを嵌め合わせることにより、構造体を伸展状態に保つことができた(図9)。また、固定具は構造体と完全に同じ空間内に納まり、伸展面に凸凹が生じないため、構造体を面材と接着する際にも固定具が邪魔になることがない。
固定具を用いることにより、セルの形状を均一に保つことができるため、構造体に強度の偏りがさらに生じにくくなった。また、伸展状態で自立させることができるため、作業効率を向上させることができた。さらに、縦芯に負荷をかけず伸展状態を維持できるため、縦芯が撓むという問題がなくなり、後工程の縦芯カットへの支障がなくなった。
As a result of repeating the trial production, in the configuration in which only the uppermost and lowermost plate base materials are bonded to the frame (see FIG. 8), the shape of each cell may be non-uniform. Attempts were made to develop a fixture that can be adjusted to a certain level and can hold the structure in an extended state.
A fixture for fixing the 2.5 mm-thick plate base material (MDF) · 28 structure manufactured in Example 2 was prepared. The fixture is a plate made of 2.5 mm thick MDF, using a plate with a length of about 780 mm and a width of 25 mm, with a groove width (length in the plate length direction) at one edge along its longitudinal direction. 15 U-shaped grooves (notches) of about 5 mm and groove depth (length in the width direction of the plate) of about 15 mm were provided at a pitch of about 55 mm. Only the both ends of the fixture were cut out in an L shape, and when both ends of the fixture were bonded to the vertical core of the frame, a U-shaped groove was formed between the wall of the frame.
On the other hand, at one edge along the longitudinal direction of the plate base material of the structure body, a U-shaped groove with a groove width of about 2.5mm and a groove depth of about 10mm A groove (notch) in the mold was made. Notches were provided in the longitudinal direction instead of all the bonded portions. By arranging this fixture perpendicular to the plate base material and fitting the notches of both, the structure could be maintained in the extended state (FIG. 9). In addition, since the fixture is housed in the same space as the structure and no unevenness is generated on the extended surface, the fixture does not get in the way when the structure is bonded to the face material.
By using the fixture, the shape of the cell can be kept uniform, so that the structure is less likely to be uneven in strength. In addition, work efficiency can be improved because it can be self-supported in the extended state. Furthermore, since the extended state can be maintained without applying a load to the vertical core, there is no problem that the vertical core is bent, and there is no hindrance to the vertical core cutting in the subsequent process.
本発明の構造体は、平面内で伸展するだけでなく、積層方向に対して湾曲させることにより、曲面形状にも対応することができる。曲面形状に湾曲させた状態で自立させるため、所望する形状に合わせた固定具を3mm厚のMDFで作ったところ、自立した曲面パネルを製造することができた。
図5に固定具の例を示し、図10に、固定具によりS字状に固定され、片面に化粧シートが貼付された構造体を示す。
本発明の構造体は、力の加減により、伸縮程度を調節しながら曲面状とすることができる。
そのため、固定具として直径200mm、150mm、130mmのリング状の固定具、半径100mm、75mm、65mmの半円状の固定具を用いたところ、同じ構造体で、半径の異なる円柱体、半円柱体を製造することができた。また円錐形状とすることも可能であり、一部平面・一部曲面の形状にも自在に対応させることができた。
The structure of the present invention not only extends in a plane, but can also correspond to a curved shape by curving in the stacking direction. In order to make it stand in a curved shape, it was possible to produce a self-supporting curved panel by making a fixture that fits the desired shape with 3mm thick MDF.
FIG. 5 shows an example of a fixture, and FIG. 10 shows a structure that is fixed in an S shape by the fixture and has a decorative sheet attached to one side.
The structure of the present invention can be formed into a curved surface while adjusting the degree of expansion and contraction by adjusting the force.
Therefore, when using a ring-shaped fixture with a diameter of 200 mm, 150 mm, or 130 mm, and a semicircular fixture with a radius of 100 mm, 75 mm, or 65 mm as the fixture, a cylindrical body or a semi-cylindrical body with the same structure but different radii Could be manufactured. Moreover, it was possible to make it into a conical shape, and it was possible to freely correspond to the shape of a partly flat surface and partly curved surface.
固定具6としては、細長い形状の部材からなり、その長手方向の周縁に多数のコの字型(またはU字型)の切り欠き7が設けられているものが好ましい。形状は、所望する構造体の変形形状に合わせればよく、例えば、図5に示すように、一部平面・一部曲面とする場合は一部直線・一部曲線に形成された固定具(A・B)を、円柱状とする場合はリング状の固定具(C)を、S字状とする場合はS字状の固定具(D)を用いる。また、平面内で伸展させて固定するには、図7(C)のように、直線上の固定具を用いる。
上記実施例のように、固定具と板基材の幅が同じであり、且つ、双方の切り欠きの深さの合計が板基材の幅と同じ(若干大きくてもよい)であれば、固定具と構造体は完全に同じ空間内に収まり、伸展により形成された面上に凸凹は生じない。そのため、構造体の伸展面に表装材を貼り付ける場合などにも、板基材・固定具と表装材との均一な接着が保たれ、且つ、平坦な表装表面が形成される(図10参照)。
The fixture 6 is preferably made of a member having an elongated shape and provided with a number of U-shaped (or U-shaped) notches 7 on the periphery in the longitudinal direction. The shape may be adjusted to the desired deformed shape of the structure. For example, as shown in FIG. 5, in the case of a partial plane / partial curved surface, a fixture (A When using B) as a cylinder, use a ring-shaped fixture (C). When using B-shape, use an S-shaped fixture (D). Moreover, in order to extend and fix in a plane, a linear fixing tool is used as shown in FIG.
As in the above example, if the width of the fixture and the plate base material is the same, and the total depth of both notches is the same as the width of the plate base material (may be slightly larger), The fixture and the structure are completely contained in the same space, and there is no unevenness on the surface formed by extension. Therefore, even when a cover material is pasted on the extended surface of the structure, a uniform adhesion between the plate base material / fixture and the cover material is maintained, and a flat surface is formed (see FIG. 10). ).
2.5mm厚のMDFの代わりに、2.5mm厚の合板を用いた他は、実施例2と同様にして、板基材28枚からなる同じ構成の構造体を製造した。
実施例2と同じように、この構造体を引き伸ばして、最上端と最下端の板基材を枠体の縦芯に接着した(図8の状態)。合板はMDFより剛性が高いため、MDF16枚の場合と同様、枠体の縦芯は内側に撓んだ。
このため、実施例4とおなじ固定具を用いて構造体の伸展状態を保持し、枠体内に納めたところ(図9の状態)、縦芯の撓みを押さえることができた。
A structure having the same structure consisting of 28 plate base materials was manufactured in the same manner as in Example 2 except that a 2.5 mm thick plywood was used instead of the 2.5 mm thick MDF.
As in Example 2, this structure was stretched, and the uppermost and lowermost plate substrates were bonded to the vertical core of the frame (state shown in FIG. 8). Since the plywood has higher rigidity than the MDF, the vertical core of the frame is bent inward as in the case of 16 MDF.
For this reason, the extension state of the structure was held using the same fixing tool as in Example 4 and placed in the frame (the state shown in FIG. 9), and the bending of the vertical core could be suppressed.
ドア内部の空気を外部に流動させることができる構造体の作成を試みた。ドアに関しては、ドア内部の空気を外部に流動させる仕様があるが、既存のペーパーハニカムでは空気を流動させることが出来ない。実施例2と同様の構造体について、各板基材の板面に、直径12mmの貫通孔8(空気穴)を、上下いずれの板基材とも接着していない箇所の板面に一カ所ずつ設けたところ(図6B)、ドア内部における空気の流動が確認できた。なお、図6Aは、実施例7にかかる構造体の正面図を模式的に示す図であって、構成を説明するために各板基材間に隙間を設け、接着箇所を[]にて示した図である。図6Bは、Aの底面図である。 An attempt was made to create a structure that can flow the air inside the door to the outside. Regarding the door, there is a specification that allows the air inside the door to flow to the outside, but the existing paper honeycomb cannot flow the air. About the structure similar to Example 2, 12 mm diameter through-holes 8 (air holes) are formed on the plate surface of each plate substrate, one on each plate surface where the upper and lower plate substrates are not bonded. When provided (FIG. 6B), the flow of air inside the door could be confirmed. FIG. 6A is a diagram schematically showing a front view of the structure according to Example 7. In order to explain the configuration, a gap is provided between each plate base material, and an adhesion portion is indicated by []. It is a figure. 6B is a bottom view of A. FIG.
パレットとして使用することを目的として、厚み4mm、幅170mm、長さ1190mmの板基材2(材質:MDF)36枚を用いて、本発明にかかる構造体1を製造した。接着部の長さはそれぞれ50mmとし、2枚の板基材間における非接着部の長さは330mmとした。図7に本実施例にかかる構造体を示す。図7の底面図(A)に示すように、各板基材2の板面に、80mm×170mmの長方形の貫通孔9(フォーク挿通孔)を2カ所設けた。また、各板基材の長手方向沿いの一縁に、深さ60mmのコの字型の切り欠き5を3カ所(各端部から25mmの箇所および板基材の中央部)に設けた。
さらに、図7(C)に示すように、固定具6として、厚み4mm・幅170mm・長さ900mmの板(材質:MDF)を用意し、その長手方向沿いの一縁に、幅8mm、深さ110mmのコの字型の切り欠き7を一定のピッチで18箇所形成した。
構造体1の切り欠き5に固定具6の切り欠き7を差し込んで、構造体1を伸展状態で固定し、長方形の孔9にフォークリフトのフォーク10を差し込んでパレットとして使用した。図7(B)は伸展状態の正面図であって、フォークリフトのフォーク10を挿通した状態を示す。構造体に約1.5トンの荷物を置いて、昇降・移動を行ったところ、構造体は破損することなく、また、何ら不都合を生じることなくパレットとして使用可能であった。
構造体の強度を調べるため、プレスしたところ、30トンのプレス圧をかけても破損しなかった。このことから、荷物運搬用パレットとしての使用に十分耐えることが実証された。
図11に、本実施例と同様の構造体(板基材の枚数、接着部の数等は異なる)の非伸展時の写真を、図12に伸展状態で固定した写真を示す。図11に示すように、構造体は、固定具を外せば元の積層状態に戻るため、積層方向の寸法は、板基材の厚み×板基材の枚数程度となる。したがって、非使用時は非常にコンパクトに収納でき、持ち運びにも非常に便利である。従来のパレットにこのような機能はなく、本発明によって十分な強度を有するとともに、非使用時にはコンパクトに収納・運搬ができるパレットを提供することができる。
For the purpose of use as a pallet, the structure 1 according to the present invention was manufactured using 36 plate base materials 2 (material: MDF) having a thickness of 4 mm, a width of 170 mm, and a length of 1190 mm. The length of the bonded portion was 50 mm, and the length of the non-bonded portion between the two plate base materials was 330 mm. FIG. 7 shows a structure according to this example. As shown in a bottom view (A) of FIG. 7, two 80 mm × 170 mm rectangular through holes 9 (fork insertion holes) were provided on the plate surface of each plate substrate 2. Further, a U-shaped notch 5 having a depth of 60 mm was provided at three locations (a location 25 mm from each end and the central portion of the plate substrate) on one edge along the longitudinal direction of each plate substrate.
Further, as shown in FIG. 7C, a plate (material: MDF) having a thickness of 4 mm, a width of 170 mm, and a length of 900 mm is prepared as the fixture 6, and a width of 8 mm and a depth are formed on one edge along the longitudinal direction. 18 U-shaped notches 7 having a thickness of 110 mm were formed at a constant pitch.
The notch 7 of the fixture 6 was inserted into the notch 5 of the structure 1 to fix the structure 1 in the extended state, and the fork 10 of the forklift was inserted into the rectangular hole 9 to be used as a pallet. FIG. 7B is a front view of the extended state, and shows a state in which the fork 10 of the forklift is inserted. When a load of about 1.5 tons was placed on the structure and moved up and down, the structure was not damaged and could be used as a pallet without any inconvenience.
When the structure was pressed to examine the strength of the structure, it was not damaged even when a pressing pressure of 30 tons was applied. From this, it was proved that it can sufficiently withstand use as a pallet for carrying goods.
FIG. 11 shows a non-stretching photograph of the same structure (the number of plate base materials, the number of bonding portions, etc.) as in this example, and FIG. 12 shows a photograph fixed in the stretched state. As shown in FIG. 11, since the structure returns to the original laminated state when the fixture is removed, the dimension in the laminating direction is about the thickness of the plate base × the number of plate bases. Therefore, it can be stored very compactly when not in use, and is very convenient to carry. A conventional pallet does not have such a function, and according to the present invention, it is possible to provide a pallet that has sufficient strength and can be stored and transported compactly when not in use.
また、パレットとして使用する構造体として、図13および図14に模式的に示す構造体を作製した。
図13に示す構造体では、底面図(A)に示すように、板幅90mmの板基材を使用し、板面の一部を切り取って、60mm×200mmのフォーク用の孔9を設けた。使用時には正面図(B)に模式的に示すように、(C)の固定具6を使用して構造体1を伸展状態で固定し、フォーク10を孔9に入れて使用する。
図14に示す構造体では、板幅40mmの板基材からなる構造体に、板幅90mmの固定具6を差し込んで使用する。図14(A)は固定具6を使用した状態の底面図であり、(B)はその正面図を模式的に示す図であり、(C)は固定具を示す図である。
Moreover, as a structure used as a pallet, a structure schematically shown in FIGS. 13 and 14 was produced.
In the structure shown in FIG. 13, as shown in the bottom view (A), a plate substrate having a plate width of 90 mm was used, and a part of the plate surface was cut out to provide a fork hole 9 of 60 mm × 200 mm. . At the time of use, as schematically shown in the front view (B), the structural body 1 is fixed in the extended state using the fixture 6 of (C), and the fork 10 is put into the hole 9 for use.
In the structure shown in FIG. 14, a fixture 6 having a plate width of 90 mm is inserted into a structure made of a plate base material having a plate width of 40 mm. FIG. 14A is a bottom view in a state where the fixture 6 is used, FIG. 14B is a diagram schematically showing a front view thereof, and FIG. 14C is a diagram showing the fixture.
このように、パレットとして使用する場合も、様々な実施態様が可能であり、積荷の重さや使用目的に応じて適切な構造体を製造することができる。 Thus, when using as a pallet, various embodiments are possible, and an appropriate structure can be manufactured according to the weight of the load and the purpose of use.
長手方向における接着部の長さ、セルの一辺の長さ等を検討した。
接着部の長さは、伸展時にかかる力によって板基材同士が剥離しない強度を達成できればよいため、所望するセルの開口高さによって変わるが、一般に20mm以上とすることが強度を保つ上で好ましかった。一例を挙げると、2〜3mm厚のMDF(長さ2150mm、幅150mm)では、接着部の長さが10mm程度では、伸展時に接着部がはずれやすく、十分に伸展させることができなかった。しかし、より剛性の弱い板基材を用い、開口高さを小さく設定する場合(例えば10mm程度)には、接着部の長さ10mm程度でも剥離なく伸展させることができた。
家具や建具のコア材として使用する場合は、一般に20mm以上とすることが好ましく、40〜60mm程度がより好ましかった。
また、異なる種類の板について、その剛性を検討するため、板の両端が持ち上がらない・且つ滑る程度に木材で押さえて、0.5kgの力で引っ張った際、50mm持ち上がるピッチ(セルの一辺の長さに相当)を調べたところ2.5mm厚のMDFでは380mm、3mm厚のMDFでは490mm、4mm厚のMDFでは650mm、2mm厚の樹脂板(塩化ビニル樹脂)では350mmとなった(板幅は全て30mm)。
この結果から、同じ力を掛けた際に同じ伸展率を希望する場合、板基材の剛性が強ければ、セルの一辺の長さを長くして対応すればよいことが分かるが、セルの一辺の長さが長すぎると強度が落ちるため、一般に、上述した状況において0.5kgの力で引っ張った際、50mm持ち上がるピッチが300〜800mm程度の剛性を有する板基材が好ましい。特に、家具や建築材のコア材として用いる場合は、上記ピッチが300〜500mm程度となる剛性を有する板基材が好ましく、パレットとして用いる場合は上記ピッチが400〜800mm程度となる剛性を有する板基材が好ましい。
The length of the adhesion part in the longitudinal direction, the length of one side of the cell, etc. were examined.
The length of the bonded portion only needs to achieve a strength at which the plate base materials do not peel off due to the force applied at the time of extension, and therefore varies depending on the desired opening height of the cell. Generally, a length of 20 mm or more is preferable for maintaining strength. It was good. As an example, with an MDF having a thickness of 2 to 3 mm (length 2150 mm, width 150 mm), if the length of the bonded portion was about 10 mm, the bonded portion was easily detached at the time of extension, and could not be sufficiently extended. However, when a plate base material having a lower rigidity was used and the opening height was set to be small (for example, about 10 mm), the adhesive part could be extended without peeling even if the length was about 10 mm.
When used as a core material for furniture or joinery, generally it is preferably 20 mm or more, more preferably about 40 to 60 mm.
Also, in order to study the rigidity of different types of plates, both ends of the plate do not lift up, and the pitch that lifts by 50 mm when pressed with wood and pulled with a force of 0.5 kg (the length of one side of the cell) Was 380 mm for 2.5 mm thick MDF, 490 mm for 3 mm thick MDF, 650 mm for 4 mm thick MDF, and 350 mm for 2 mm thick resin board (vinyl chloride resin) (all board widths were 30 mm) ).
From this result, it can be seen that if the same extension rate is desired when the same force is applied, if the plate base material is strong, the length of one side of the cell can be increased. If the length is too long, the strength is lowered. Therefore, in general, a plate base material having a rigidity with a pitch of 50 mm lifting about 300 to 800 mm when pulled with a force of 0.5 kg in the above-described situation is preferable. In particular, when used as a core material for furniture or building materials, a plate substrate having a rigidity of about 300 to 500 mm is preferable, and when used as a pallet, a plate having a rigidity of about 400 to 800 mm when the pitch is used. A substrate is preferred.
さらに、家具や建築材のコア材として使用するのに好適な構造体について検討するために、MDFからなる構造体について、板基材の幅を15〜35mm、板基材の厚みを1〜4mm、接着部の長さを20〜60mmに変化させて様々な構造体を試作し、適切なセルの一辺の長さ(2枚の板基材間における非接着長さ)を検討した。結果を表1にまとめる。
また、パレット等として使用するのに好適な構造体について検討するために、塩化ビニル樹脂からなる構造体について、板基材の幅を100〜200mm、板基材の厚みを2〜4mm、接着部の長さを30〜70mmに変化させて様々な構造体を試作し、適切なセルの一辺の長さを検討した。結果を表2にまとめる。
板幅、板厚により板基材の剛性は異なるが、一般に、接着部の長さを30mm以上(より好ましくは40mm以上)とした構造体が取り扱い易かった。
なお、MDFからなる板基材であっても、化粧板(両面化粧シート貼り)を用いた場合は、開閉を繰り返すうちにシート層が剥離してくるため、表面にシート層がない板基材を用いることが好ましかった。
Although the rigidity of the plate base material varies depending on the plate width and plate thickness, in general, a structure with an adhesive portion length of 30 mm or more (more preferably 40 mm or more) was easy to handle.
Even if it is a plate substrate made of MDF, if a decorative board (double-sided decorative sheet attached) is used, the sheet layer peels off as it is repeatedly opened and closed, so there is no sheet layer on the surface. Was preferred.
メラミン樹脂からなる板基材を使用して構造体を製造した。厚み1.2mm、幅25mm、長さ2150mmのメラミン板を板基材として用い、実施例2と同様、接着部の長さ50mm、セルの一辺の長さ370mmの構造体を作成した。また、板基材に実施例4と同様の構成の切り欠き(溝幅:約1.2mm 溝深さ:約10mm)を形成し、併せて、厚み1.2mmのメラミン板からなり、溝幅が約2.4mm、溝深さが約15mmの切り欠きを有する、実施例4の固定具と同様の構成を持つ固定具を作成した。
材質をメラミン樹脂とした場合も、木質材を用いた場合と同様、平面形状および曲面形状に伸展可能な構造体を作製することができた。
また、当該メラミン構造体は3mmMDF構造体よりも軽く、最上端と最下端の板基材をドア用枠体の縦芯に固定して(固定具を用いず)伸展状態を維持する場合も、自重で曲がる恐れが少なくなった。
A structure was produced using a plate substrate made of melamine resin. A melamine plate having a thickness of 1.2 mm, a width of 25 mm, and a length of 2150 mm was used as a plate base material, and a structure having an adhesive portion length of 50 mm and a cell side length of 370 mm was prepared in the same manner as in Example 2. In addition, a notch (groove width: about 1.2 mm, groove depth: about 10 mm) having the same configuration as that of Example 4 is formed on the plate base material, and is composed of a melamine plate having a thickness of 1.2 mm. A fixture having the same configuration as the fixture of Example 4 having a notch of 2.4 mm and a groove depth of about 15 mm was produced.
When the material was melamine resin, it was possible to produce a structure that could be extended into a planar shape and a curved shape, as in the case of using a woody material.
In addition, the melamine structure is lighter than the 3 mm MDF structure, and the plate base at the uppermost end and the lowermost end is fixed to the vertical core of the door frame (without using a fixture) to maintain the extended state. The risk of bending under its own weight has decreased.
板幅を6.75mmとした以外は実施例4と同様の構造体を作製し、この構造体を2つ用いてフラッシュドアを作成した。厚み11.5mm、幅850mm×高さ2000mmの合板の両面に、固定具で伸展状態に維持した構造体を貼り付け一枚のプレートにした(すなわち、合板が2つの構造体でサンドイッチされた構成を持つ)。さらに、このプレートの両面に厚さ2.5mmの化粧板を張り付けて、フラッシュドアを作成した。図15にこのフラッシュドアの断面図を模式的に示す。図15に示すように、本実施例にかかるフラッシュドアの断面は、「化粧板12/構造体1/合板11/構造体1/化粧板12」という構成になり、ドア厚みは30mm(2.5mm+6.75mm+11.5mm+6.75mm+2.5mm)である。13は木口面に貼る木口テープである。従来のフラッシュドアの製造工程には、芯組み工程(ドアの形作り)が必要であったが、本実施例の方法により製造したフラッシュドアは、中央に合板が挟まれているため、どの部分を切っても中にビスを止められる木質部(合板部)があるため、従来の芯組み工程を必要としない。
また、ドア木口面に貼るテープとして、約2mm程度の厚手のテープを用いることにより、ドアの側面を凸凹感無くカバーすることができた。また、金物を入れビスを固定することも可能であった。
A structure similar to that of Example 4 was prepared except that the plate width was 6.75 mm, and a flash door was formed using two of the structures. A structure maintained in a stretched state with a fixture is attached to both sides of a plywood board with a thickness of 11.5 mm, a width of 850 mm, and a height of 2000 mm to form a single plate (ie, a plywood sandwiched between two structures). Have). In addition, a 2.5mm thick decorative board was attached to both sides of the plate to create a flash door. FIG. 15 schematically shows a cross-sectional view of the flash door. As shown in FIG. 15, the cross section of the flash door according to the present embodiment has a configuration of “decorative board 12 / structure 1 / plywood 11 / structure 1 / decorative board 12”, and the door thickness is 30 mm (2.5 mm + 6 .75mm + 11.5mm + 6.75mm + 2.5mm). Reference numeral 13 denotes a lip tape attached to the lip face. The conventional flash door manufacturing process required a core assembly process (making the door), but the flash door manufactured by the method of this embodiment has a plywood sandwiched in the center, Since there is a wood part (plywood part) that can stop the screw even if it is cut, a conventional core assembly process is not required.
In addition, by using a thick tape of about 2mm as the tape to be applied to the door mouth, we were able to cover the side of the door without any unevenness. It was also possible to insert a hardware and fix the screw.
実施例6で製造した構造体(2.5mm厚の合板製)を固定具で伸展状態に維持したままドア用枠体内に固定し(図9参照)、その両側に厚み約2.5mmの面材を貼り付けてフラッシュドアを作製した。ドア用枠体は、幅約35mm・厚み約25mmの角材を用いて構成した。ドアの仕上がり寸法は、ドア幅約850mm・ドア高さ約2000mm・ドア厚み約30mmである。このフラッシュドア(以下、ドアAと称する)および、実施例12で製造したフラッシュドア(以下、ドアBと称する)について、反り環境試験を行った。面材には、表側にオレフィンシート、裏側に防湿シートが貼付された面材を使用した。面材と枠材・構造体は、酢酸ビニルエマルジョン型接着剤で接着した。接着剤の塗布量は190g/m2とした。また、従来品である紙製のハニカムコアを用いた同じサイズのフラッシュドアを作成し、比較例とした。 The structure manufactured in Example 6 (made of 2.5 mm thick plywood) is fixed in the door frame while maintaining the extended state with a fixture (see FIG. 9), and a face material having a thickness of about 2.5 mm is formed on both sides thereof. A flash door was prepared by pasting. The door frame was made of square material with a width of about 35mm and a thickness of about 25mm. The finished dimensions of the door are a door width of about 850mm, a door height of about 2000mm, and a door thickness of about 30mm. A warpage environment test was performed on the flash door (hereinafter referred to as door A) and the flash door manufactured in Example 12 (hereinafter referred to as door B). As the face material, a face material having an olefin sheet on the front side and a moisture-proof sheet on the back side was used. The face material and the frame material / structure were bonded with a vinyl acetate emulsion adhesive. The amount of adhesive applied was 190 g / m 2 . In addition, a flush door of the same size using a paper honeycomb core, which is a conventional product, was prepared and used as a comparative example.
温度湿度を制御できる2部屋(A室・B室とする)の境に各ドアを設置して試験を行った。A室の温湿度を40℃/90%R.H.で16時間維持した後、20℃/55%R.H.で8時間維持し、これをもう1サイクル繰り返した。この間、B室の温湿度は20℃/55%R.H.のまま維持した。フラッシュドアの9箇所について面材の変位量および反り変形量を測定し、試験中の最大たわみと経緯、試験後の残留たわみを観察した。
ドアAおよびドアBいずれについても、ペーパーハニカムを用いた比較用のフラッシュドアと比べて反りや変形が小さく、強度に優れていた。
Each door was installed on the boundary between two rooms (room A and room B) where the temperature and humidity could be controlled, and the test was conducted. The temperature and humidity in room A was maintained at 40 ° C./90% RH for 16 hours, and then maintained at 20 ° C./55% RH for 8 hours, and this was repeated for another cycle. During this time, the temperature and humidity in the room B were maintained at 20 ° C./55% RH. The displacement amount and warpage deformation amount of the face material were measured at nine locations of the flash door, and the maximum deflection and history during the test and the residual deflection after the test were observed.
Both door A and door B were less warped and deformed than the comparative flash door using a paper honeycomb, and were excellent in strength.
本発明の構造体は、平面状の建具のみならず、曲面状の家具や柱のコア材として用いるのに非常に適しており、これらの性能を向上させることができる(反り曲がりを防ぐ)。また、トン単位の負荷がかかるフォークリフト用のパレットとしても利用できる。また、建具等の製造工程で発生する木質板の端材を利用して製造することができるため、木質材の有効活用にも繋がり、リサイクルに資する。そして、木材や金属の板から製造できるため、従来から存在する段ボール製のハニカムコアやパレットに比べて高強度の構造体を作製することができる。特にパレットとして使用する場合、積荷の重さに耐えるだけでなく、フォークリフトの爪でも破損されにくいため、非常に実用性が高い。さらに、非使用時(非伸展状態時)には非常にコンパクトなサイズとなるため、収納や運搬に便利である。 The structure of the present invention is very suitable for use as a core material for curved furniture and pillars as well as flat joinery, and can improve these performances (preventing warping and bending). It can also be used as a pallet for forklifts that are loaded with tons. Moreover, since it can manufacture using the end material of the wooden board which generate | occur | produces in manufacturing processes, such as joinery, it leads also to the effective utilization of a wooden material and contributes to recycling. And since it can manufacture from a board | plate of wood or a metal, a high intensity | strength structure can be produced compared with the honeycomb core and pallet made from a corrugated cardboard which exist conventionally. In particular, when used as a pallet, it not only withstands the weight of the load, but is also very practical because it is not easily damaged by the forklift claws. Furthermore, since it is a very compact size when not in use (when not extended), it is convenient for storage and transportation.
