Description

本発明は、芯材の少なくとも一方の側端面において、繋ぎ目部を形成するように表面材の端部同士を対向させて該芯材の外表面に該表面材を貼着した建築用パネル材に関する。   The present invention provides a building panel material in which at least one side end surface of a core material is bonded to the outer surface of the core material with the end surfaces of the surface material facing each other so as to form a joint portion. About.

建物の内装材や家具材等に用いられる建築用パネル材としては、合板やパーティクルボード、或いはインシュレーションボードやＭＤＦなどの木質繊維板等の板状とされた木質系材料を芯材として、該芯材の外表面（表裏面、側端面（木口面）等）に、表面化粧用の表面材を貼着したパネル材が提供されている。このような芯材に、表面化粧用の表面材を貼着する場合は、当該芯材の表裏面及び側端面等に直接、樹脂シートや突板等の化粧シート（表面材）を貼着する構成とされている。   As building panel materials used for building interior materials and furniture materials, plywood, particle boards, or wood-based materials such as insulation fiber boards or wood fiber boards such as MDF are used as core materials. A panel material is provided in which a surface material for surface decoration is attached to the outer surface (front and back surfaces, side end surfaces (front end surface), etc.) of a core material. In the case of attaching a surface material for surface decoration to such a core material, a configuration in which a decorative sheet (surface material) such as a resin sheet or a veneer is directly attached to the front and back surfaces and side end surfaces of the core material. It is said that.

また、上記のような芯材としては、上記板状とされた芯材以外に、枠組み形成された外枠内にコア材等を充填、配設したものや、ガラスパネル等の面材を嵌め込むための開口部を設けた芯材等が用いられている。
このような芯材に、表面化粧用の表面材を貼着する場合には、まず、薄板状の木質系材料からなる面材を芯材の表裏面に貼り付け、次いで、樹脂シートや突板等の化粧シートを該面材の表面及び芯材の側端面等に貼着する構成とされている。或いは、面材を基材として、該基材の表面に予め化粧シートを貼着した表面材を、芯材の表裏面及び側端面等に貼着する構成とされている。 In addition to the plate-shaped core material, the core material is filled with a core material or the like in a frame-formed outer frame, or a face material such as a glass panel is fitted. The core material etc. which provided the opening part for inserting are used.
When sticking a surface material for surface decoration to such a core material, first, a face material made of a thin wooden material is attached to the front and back surfaces of the core material, and then a resin sheet, a veneer, etc. The decorative sheet is attached to the surface of the face material, the side end face of the core material, and the like. Or it is set as the structure which sticks the surface material which adhered the decorative sheet beforehand to the surface of this base material on the surface of a base material, the front and back, a side end surface, etc. by using a face material as a base material.

上記のように表面材を、上記芯材の表裏面及び側端面に貼着する場合には、当該表面材の端部同士の繋ぎ目部（突合わせ部或いは目地部、重ね部）が建築用パネル材自体の表面側或いは裏面側に位置すると、見栄えが悪いため、当該繋ぎ目部が、芯材の側端面に位置するようにして、その表面材の貼着がなされている。
上記のように表面材の繋ぎ目部を、芯材の側端面に位置させた建築用パネル材においては、従来は、表面材を、芯材の表面及び裏面にそれぞれ貼着し、側端面に、別の表面材（エッジシートとも言う）を貼着する構成とされたものがあった。
或いは、芯材の表面に貼着した化粧シートと、裏面に貼着した化粧シートとを側端面において、一部重ねるようにして貼着する構成とされたものもあった。 When the surface material is adhered to the front and back surfaces and the side end surfaces of the core material as described above, the joint portion (butting portion or joint portion, overlapping portion) between the end portions of the surface material is for construction. When it is located on the front side or the back side of the panel material itself, it does not look good. Therefore, the surface material is adhered so that the joint portion is located on the side end surface of the core material.
In the construction panel material in which the joint portion of the surface material is positioned on the side end surface of the core material as described above, conventionally, the surface material is pasted on the front surface and the back surface of the core material, respectively, There was a configuration in which another surface material (also referred to as an edge sheet) was attached.
Alternatively, there has been a configuration in which a decorative sheet attached to the surface of the core material and a decorative sheet attached to the back surface are attached so as to partially overlap each other at the side end face.

前者のエッジシートを貼着する構成とされたものでは、芯材の表裏面と端面との縁部（角部）において、それら表面材同士にズレや隙間が生じないよう突合わせて貼着する必要があり、その貼着工程において高い精度が要求されるものであった。また、該突合わせ部が、角部に位置することから、剥がれ易くなるといった問題があった。さらに、角部を境に表面材の模様の連続性が失われてしまうので、見栄えが悪くなるという問題もあった。
また、後者の化粧シートを側端面において重ねる構成とされたものでは、貼着工程において、上記したような高い精度が要求されるものではないが、当該重ね部において段差が生じる。このような段差が生じると、重ねられた上側の化粧シートの端面には、通常、模様等が施されておらず白色等であるため、当該端面が露出することから、見栄え等が悪いという問題があった。また、当該重ね部において化粧シートが剥がれ易くなるという問題があった。 In the case where the former edge sheet is configured to be adhered, the edge portions (corner portions) between the front and back surfaces and the end surfaces of the core material are abutted and adhered so that no deviation or gap occurs between the surface materials. Therefore, high accuracy is required in the attaching process. In addition, since the butted portion is located at the corner, there is a problem that it is easy to peel off. Furthermore, since the continuity of the pattern of the surface material is lost at the corner, there is a problem that the appearance is deteriorated.
Further, in the case where the latter decorative sheet is configured to be overlapped on the side end surface, the above-described high accuracy is not required in the attaching step, but a step is generated in the overlapped portion. When such a step occurs, the end face of the upper decorative sheet that is overlaid is usually white or the like without a pattern or the like, and the end face is exposed, so that the appearance is poor. was there. Further, there is a problem that the decorative sheet is easily peeled off at the overlapped portion.

下記特許文献１では、上記したような問題を解決するために、芯材の表裏面及び側端面に化粧材を貼着した扉パネルが提案されている。
この扉パネルは、裏面にＶ字状の折曲溝を有する化粧材を、芯材の表面側及び裏面側から芯材の側端面まで芯材の角部に対応する部分で折り曲げ、同化粧材の各側端面が芯材の側端面において相互に対向するようにそれぞれ貼着し、その対向部分に所定幅の溝を形成して同溝に目地部材を装着する構成とされている。このものでは、上記表面化粧材及び裏面化粧材の各側端面を、芯材の側端面において相互に僅かに隙間を有して対向するように貼着し、次いで、所定の径のルーター等により該隙間に沿って所定幅寸法に切削することによって、上記目地部材を装着する溝を形成するようにしている。
上記特許文献１に記載の扉パネルによれば、上記のように側端面にて対向される化粧材の対向部位に、所定幅寸法の溝を形成し、該溝に目地部材を埋設するようにしているので、加工精度のバラツキが当該溝により吸収されることとなり、接合面にスキマや段差の生じない扉パネルが得られる、と説明されている。
特開２００５−３３６７８３号公報（図４参照） In the following Patent Document 1, in order to solve the above-described problem, a door panel in which a decorative material is attached to the front and back surfaces and side end surfaces of the core material is proposed.
In this door panel, a decorative material having a V-shaped bent groove on the back surface is bent at a portion corresponding to a corner portion of the core material from the front surface side and the back surface side to the side end surface of the core material. Each side end face is attached so that it faces each other on the side end face of the core member, a groove having a predetermined width is formed in the facing portion, and a joint member is mounted in the groove. In this case, the respective side end surfaces of the surface decorative material and the back surface decorative material are attached so as to face each other with a slight gap on the side end surface of the core material, and then, by a router or the like having a predetermined diameter. By cutting to a predetermined width along the gap, a groove for mounting the joint member is formed.
According to the door panel described in Patent Document 1, a groove having a predetermined width dimension is formed in the facing portion of the decorative material opposed at the side end face as described above, and the joint member is embedded in the groove. Therefore, it is described that the variation in processing accuracy is absorbed by the groove, and a door panel in which no gap or step is generated on the joint surface is obtained.
Japanese Patent Laying-Open No. 2005-336783 (see FIG. 4)

しかし、上記特許文献１に記載の扉パネルでは、当該パネルの側端面において対向される化粧材の端面同士の間に、隙間を有するように化粧材を貼着した後、切削加工により所定幅寸法の溝を形成し、さらに、別部材とされた目地部材を埋設する必要があり、更なる製造工程の簡略化が望まれていた。   However, in the door panel described in Patent Document 1, after the decorative material is attached so as to have a gap between the end surfaces of the facing materials facing each other at the side end surfaces of the panel, the predetermined width dimension is obtained by cutting. In addition, it is necessary to embed a joint member as a separate member, and further simplification of the manufacturing process has been desired.

本発明は、上記実情に鑑みなされたものであり、芯材の側端面において形成される表面材の繋ぎ目部の隙間を簡易な構造で隠蔽し、意匠性を高め得る建築用パネル材を提供することを目的としている。   The present invention has been made in view of the above circumstances, and provides an architectural panel material capable of concealing a gap at a joint portion of a surface material formed on a side end surface of a core material with a simple structure and enhancing design properties. The purpose is to do.

前記目的を達成するために、本発明に係る建築用パネル材は、芯材の少なくとも一方の側端面において、繋ぎ目部を形成するように表面材の端部同士を対向させて該芯材の外表面に該表面材を貼着した建築用パネル材であって、前記表面材は、薄板状の基材の表面に弾性を有する化粧シートを貼着した構造とされ、前記側端面において対向される表面材の両方の端部には、表面側部位を延出させた折込み代がそれぞれに設けられており、これら両方の端部の裏面側部位の端面同士が前記側端面において対向されて形成された隙間に両方の端部のそれぞれの折込み代が折込まれ、これら折込み代が互いに弾接されて該隙間を塞ぐ構造とされていることを特徴とする。 In order to achieve the above-mentioned object, the building panel material according to the present invention is such that at least one side end surface of the core material is formed by facing the end portions of the surface material so as to form a joint portion. An architectural panel material having the surface material adhered to an outer surface, wherein the surface material has a structure in which a decorative sheet having elasticity is adhered to the surface of a thin plate-like substrate, and is opposed to the side end surface. that the ends of both the surface material is provided on the folding was extended surface side portion margin respectively, end faces of the back side portion of both ends is opposite the said end face A feature is that the respective folding margins of both ends are folded into the formed gap, and the folding margins are elastically contacted with each other to close the gap.

また、前記建築用パネル材においては、前記折込み代を、前記表面材の基材の化粧シート側部位を残すようにして切除された該基材の残余部位と、該残余部位の表面側の化粧シートとからなるものとしてもよい。この構成においては、前記折込み代の裏面側基端に、溝部を形成したものとしてもよい。   Further, in the building panel material, the folding allowance is made by leaving the remaining portion of the base material cut out so as to leave the decorative sheet side portion of the base material of the surface material, and the makeup on the surface side of the residual portion It may be composed of a sheet. In this configuration, a groove portion may be formed at the rear surface side proximal end of the folding allowance.

本発明に係る建築用パネル材は、芯材の外表面に貼着される表面材を、薄板状の基材の表面に弾性を有する化粧シートを貼着した構造とし、該表面材の一方の端部に、表面側部位を延出させた折込み代を設け、該折込み代が前記表面材の他方の端部との間に形成された前記繋ぎ目部の隙間に折込まれて、該隙間を塞ぐ構造とされている。
従って、寸法誤差や取付誤差等を吸収するために形成された繋ぎ目部の隙間が、上記折込み代によって塞がれて隠蔽されるので、当該隙間が目立ち難くなり、意匠性を高めることができる。
また、表面材の前記一方の端部に形成された折込み代は、前記繋ぎ目部の隙間に折込まれているので、手前側（芯材の端面に対面した状態における手前側）に向けて突出するような段差が形成されず、意匠性に優れたものとなる。また、手前側に向けて突出するような段差が形成されないので、上述のような芯材の側端面において化粧シートを重ねるものと比べて、剥がれ難いものとなる。また、該表面材の端部は、芯材の側端面において対向されているので、上述のようなエッジシートを貼着するものと比べて、剥がれ難いものとなる。 In the building panel material according to the present invention, the surface material adhered to the outer surface of the core material has a structure in which a decorative sheet having elasticity is adhered to the surface of a thin plate-like substrate, and one of the surface materials The end portion is provided with a folding allowance extending the surface side portion, and the folding allowance is folded into a gap of the joint portion formed between the other end portion of the surface material, and the gap is formed. It has a closed structure.
Accordingly, the gap in the joint formed to absorb dimensional errors, mounting errors, etc. is blocked and concealed by the folding allowance, so that the gap is less noticeable and the design can be improved. .
Moreover, since the folding margin formed in the said one edge part of the surface material is folded in the clearance gap of the said joint part, it protrudes toward the near side (front side in the state facing the end surface of a core material). Such a step is not formed, and the design is excellent. Moreover, since the level | step difference which protrudes toward this side is not formed, it becomes a thing which is hard to peel compared with what overlaps a decorative sheet in the side end surface of the above core materials. Moreover, since the edge part of this surface material is opposed in the side end surface of a core material, it becomes a thing which is hard to peel compared with what sticks the above edge sheets.

さらに、上記のように隙間を塞ぐ部材を、表面材の表面側部位を延出させた折込み代としているので、該表面材の表面側に位置する化粧シートの弾性により、当該折込み代が弾性変形部として機能する。これにより、上記隙間に折込まれた際には、上記表面材の他方の端部の端面に弾接するようにして上記隙間を塞ぐことができる。従って、上記隙間の幅寸法が長手方向に沿って均一ではない場合でも、当該折込み代が弾接することにより、そのような誤差等も吸収でき、意匠性を高めることができる。
さらにまた、上記特許文献１に記載の扉パネルのように、当該隙間を所定幅寸法とするために切削等をする必要がないので、製造工程の簡略化が図れ、簡易な構造で上記隙間を隠蔽できる。
また、上記折込み代は、表面材の一方の端部の表面側部位を延出させたものとされているので、例えば、別部材等を、上記隙間に埋設するようなものと比べて、製造工程の簡略化が図れる。すなわち、表面材の一方の端部に形成された折込み代を、上記隙間に折込むことで、当該隙間を塞ぐことができ、製造工程の簡略化が図れ、簡易な構造で上記隙間を隠蔽できる。 Furthermore, since the member that closes the gap as described above is a folding margin that extends the surface side portion of the surface material, the folding margin is elastically deformed by the elasticity of the decorative sheet located on the surface side of the surface material. It functions as a part. Thereby, when it folds in the said clearance gap, the said clearance gap can be plugged up so that it may contact elastically with the end surface of the other edge part of the said surface material. Therefore, even when the width dimension of the gap is not uniform along the longitudinal direction, such an error or the like can be absorbed and the design can be improved by the elastic contact of the folding margin.
Furthermore, unlike the door panel described in Patent Document 1, since it is not necessary to perform cutting or the like in order to make the gap have a predetermined width, the manufacturing process can be simplified, and the gap can be formed with a simple structure. Can be concealed.
In addition, since the folding allowance extends from the surface side portion of one end of the surface material, for example, it is manufactured as compared with the case where another member is embedded in the gap. The process can be simplified. That is, by folding the folding margin formed at one end of the surface material into the gap, the gap can be closed, the manufacturing process can be simplified, and the gap can be hidden with a simple structure. .

また、前記表面材の他方の端部に、表面側部位を延出させた折込み代を更に設け、該折込み代が前記隙間に折込まれて、前記一方の端部に設けられた折込み代とにより、該隙間を塞ぐ構造としているので、より効果的に意匠性を高めることができる。
すなわち、芯材の側端面において対向される表面材の一方の端部にのみ折込み代を形成したものでは、その他方の端部の端面の一部が当該折込み代によって十分に覆い隠されず、その一部が露出する場合がある。一方、表面材の他方の端部に折込み代を更に設けたものとすれば、これら対向する端部にそれぞれ設けられた折込み代が上記隙間に折込まれることにより、上記隙間が塞がれて隠蔽されるので、対向する表面材のいずれの端部の端面もこれら折込み代により覆い隠され、意匠性に優れたものとなる。
また、上記構成によれば、上記折込み代のそれぞれが折込まれて表面側に位置する化粧シートが互いに弾接するようにして当該隙間に介在されるので、当該隙間側への折込みにより形成される表面からの窪みを、上記表面材の一方の端部にのみ折込み代を形成したものと比べて、効率的に小さくできる。
さらに、上記折込み代のそれぞれが上記隙間に折込まれているので、表面材の端部端面が露出することがなく、上記表面材の一方の端部にのみ折込み代を形成したものよりも、より剥がれ難いものとなる。 Further , the other end portion of the surface material is further provided with a folding allowance for extending the surface side portion, the folding allowance is folded into the gap, and the folding allowance provided at the one end portion And since it is set as the structure which plugs up this clearance gap, the design property can be improved more effectively.
That is, in the case where the folding margin is formed only at one end portion of the surface material facing the side end surface of the core material, a part of the end surface of the other end portion is not sufficiently covered by the folding margin, Some may be exposed. On the other hand, if the other end portion of the surface material is further provided with a folding margin, the folding margin provided at each of these opposed end portions is folded into the gap, thereby closing the gap. Since it is concealed, the end surface of any end part of the facing surface material is concealed by these folding margins, and the design is excellent.
Further, according to the above configuration, each of the folding margins is folded and the decorative sheets positioned on the surface side are interposed in the gap so as to be in elastic contact with each other, so the surface formed by folding into the gap side Can be efficiently reduced as compared with the case where the folding margin is formed only at one end of the surface material.
Further, since each of the folding allowances are folded into the gap, the end face of the surface material is not exposed, and more than the one where the folding allowance is formed only at one end of the surface material. It will be difficult to peel off.

前記建築用パネル材において、前記折込み代を、前記表面材の基材の化粧シート側部位を残すようにして切除された該基材の残余部位と、該残余部位の表面側の化粧シートとからなるものとすれば、基材の残余部位の厚さを調整することで、上記のように表面材の端部から延出させる折込み代の厚さを調整できる。
また、例えば、化粧シートのみを折込み代とする場合において、該化粧シートを基材の端部から延出させるようにして基材の表面に貼着して折込み代を有した表面材を形成する場合は、その折込み代を構成する化粧シートの延出幅を略均一にする必要があることから、その貼着工程において高い精度が必要となる。一方、上記のように、前記表面材の基材の化粧シート側部位を残すようにして切除して、その基材の残余部位と化粧シートとにより折込み代を構成するものとすれば、容易に、かつ精度良く折込み代を形成することができる。さらに、化粧シートが比較的薄い場合等で、折込み代の強度を高めたい場合には、上記したように基材の残余部位の厚さを調整することで、折込み代の強度を容易に高めることができる。 In the building panel material, the folding allowance is obtained from a remaining part of the base material that has been cut out so as to leave a decorative sheet side part of the base material of the surface material, and a decorative sheet on the surface side of the residual part If it becomes, the thickness of the folding allowance extended from the edge part of a surface material as mentioned above can be adjusted by adjusting the thickness of the remaining part of a base material.
Further, for example, when only the decorative sheet is used as the folding allowance, the decorative sheet is attached to the surface of the base material so as to extend from the end of the base material to form a surface material having the folding allowance. In this case, since it is necessary to make the extending width of the decorative sheet constituting the folding margin substantially uniform, high accuracy is required in the attaching step. On the other hand, as described above, if it is cut out so as to leave the decorative sheet side part of the base material of the surface material, and the folding margin is constituted by the remaining part of the base material and the decorative sheet, In addition, the folding allowance can be formed with high accuracy. Furthermore, when the decorative sheet is relatively thin, etc., and when it is desired to increase the strength of the folding margin, the strength of the folding margin can be easily increased by adjusting the thickness of the remaining part of the base material as described above. Can do.

上記基材２２の厚さは、適宜、設定可能であるが、例えば、１．０ｍｍ〜５．０ｍｍ程度としてもよい。 Each of the surface materials 2 and 2 includes a thin plate-like base material 22 and an elastic decorative sheet 20 attached to the surface 22 a of the base material 22. The base material 22 is made of the same woody material as described above. In this embodiment, the base material 22 is relatively hard and dense, and has excellent surface smoothness. Therefore, the MDF (Medium Density Fiberboard, medium fiberboard, medium density fiber) is used. It is also called a board.
As shown in FIG. 2 (a), when the base material 22 is attached to the outer surface of the core material 1, the front and back surfaces 11, 12 and the left and right end surfaces 13, 14 of the core material 1 A bending groove 24 having a substantially V-shaped cross section is formed by cutting with a cutting tool or the like so that it can be bent at a portion corresponding to the corner. The bending groove 24 is formed by cutting the base material 22 into a V shape so that only the decorative sheet 20 of the surface materials 2 and 2 is left.
The thickness of the substrate 22 can be set as appropriate, but may be, for example, about 1.0 mm to 5.0 mm.

上記化粧シート２０は、オレフィン系樹脂などの合成樹脂系材料をシート状（フィルム状）に加工したもので、例えば、厚さが５０μｍ〜１．０ｍｍ程度の薄状のものであり、上記基材２２の表面２２ａの全面に亘って接着剤等で接着されている。本実施形態では、木目模様が施され、厚さが７０μｍ程度とされたオレフィン系樹脂シートを採用している。尚、化粧シート２０としては、弾性を有するものであれば、どのようなものでもよく、また、模様も木目に限らずどのようなものでもよい。例えば、本実施形態のように、二枚の表面材２，２を芯材１の表面側及び裏面側に貼着するものでは、これら二枚の表面材２，２の模様を異ならせたものとしてもよい。   The decorative sheet 20 is obtained by processing a synthetic resin material such as an olefin resin into a sheet (film shape), for example, a thin sheet having a thickness of about 50 μm to 1.0 mm. The entire surface 22a of 22 is bonded with an adhesive or the like. In the present embodiment, an olefin resin sheet having a grain pattern and a thickness of about 70 μm is employed. The decorative sheet 20 may be any material as long as it has elasticity, and the pattern is not limited to the grain and may be any material. For example, in the case where two surface materials 2 and 2 are attached to the front surface side and the back surface side of the core material 1 as in this embodiment, the patterns of the two surface materials 2 and 2 are different. It is good.

上記基材２２及び化粧シート２０から構成される表面材２，２は、図１に示すように、芯材１の左右端面１３，１４においてそれぞれ対向される端部に、その表面側部位を延出させた折込み代２５，２５を有している（図では、右端面１３側のみを図示しているが、左端面１４も図３（ｃ）に示すように同様である。）。
すなわち、本実施形態では、二枚の表面材２，２のそれぞれ幅方向両端部には、その表面側部位を延出させた折込み代２５がそれぞれ形成されている。 As shown in FIG. 1, the surface materials 2, 2 composed of the base material 22 and the decorative sheet 20 extend the surface-side portions to the opposite ends of the left and right end surfaces 13, 14 of the core material 1. Folding allowances 25, 25 are provided (in the figure, only the right end face 13 side is shown, but the left end face 14 is the same as shown in FIG. 3C).
That is, in this embodiment, the folding margin 25 which extended the surface side site | part is formed in each width direction both ends of the surface material 2 of 2 sheets, respectively.

上記折込み代２５は、図２（ｂ）に示すように、表面側部位を構成する化粧シート２０の延出部２１と、表面側部位を構成する基材２２の延出部２３とから構成されている。該折込み代２５は、表面材２の基材２２の端部の化粧シート２０側部位を残すようにして、切削工具等によって切除することにより略均一の厚さに形成されている。すなわち、表面材２の基材２２の化粧シート２０側部位を残すようにして、その裏面側部位を切除した基材２２の残余部位が延出部２３となり、該延出部２３と、該延出部２３の表面側に位置する化粧シート２０の延出部２１とにより折込み代２５を構成するようにしている。
上記基材２２を切除する厚さは、図２（ｂ）のように、化粧シート２０の延出部２１の裏面側に、僅かに基材２２の延出部２３が残るような厚さ（ほぼ化粧シートのみの厚さ）としてもよい。このように基材２２を一部残した場合にも、その延出部２３は比較的、薄く、また繊維質であるため、該延出部２３と、化粧シート２０の延出部２１とにより構成される折込み代２５は、適度に弾性を有し、後記するように隙間Ｓｐ（図１（ｂ）参照）に折込まれた際にも弾性を有した弾性変形部として機能する。 As shown in FIG. 2 (b), the folding allowance 25 is composed of an extending part 21 of the decorative sheet 20 constituting the surface side part and an extending part 23 of the base material 22 constituting the surface side part. ing. The folding allowance 25 is formed to have a substantially uniform thickness by cutting away with a cutting tool or the like so as to leave the decorative sheet 20 side portion of the end portion of the base material 22 of the surface material 2. In other words, the remaining part of the base material 22 that has been removed from the back surface side of the base material 22 of the base material 22 of the surface material 2 becomes the extension part 23, and the extension part 23 and the extension part 23 The folding allowance 25 is configured by the extended portion 21 of the decorative sheet 20 positioned on the surface side of the protruding portion 23.
The thickness at which the base material 22 is cut off is such that the extended portion 23 of the base material 22 remains slightly on the back side of the extended portion 21 of the decorative sheet 20 as shown in FIG. The thickness of the decorative sheet only) may be used. Even when a part of the base material 22 is left in this way, the extension portion 23 is relatively thin and fibrous, so that the extension portion 23 and the extension portion 21 of the decorative sheet 20 The constructed folding margin 25 has moderate elasticity, and functions as an elastically deformable portion having elasticity even when it is folded into the gap Sp (see FIG. 1B) as will be described later.

上記折込み代２５の厚さは、芯材１の左右端面１３，１４において、繋ぎ目部３を形成するように対向される表面材２，２の端部同士の間に形成される寸法誤差や取付誤差等の吸収のための隙間Ｓｐや化粧シート２０自体の厚さ等に応じて適宜、設定可能であるが、例えば、５０μｍ〜１．０ｍｍ程度としてもよい。本実施形態のように、７０μｍ程度の厚さとされた化粧シート２０を備えたもので、かつ、表面材２の基材２２の裏面側部位を切除することにより形成する場合は、０．１ｍｍ程度〜１．０ｍｍ程度、より好ましくは０．２ｍｍ程度〜０．５ｍｍ程度としてもよい。このように薄状の折込み代２５とすることで、その弾性変形が阻害されることなく、後記するように屈曲させて隙間Ｓｐに折込む際に、容易に折込むことができる。   The thickness of the folding allowance 25 is such that a dimensional error formed between the end portions of the surface materials 2 and 2 facing each other so as to form the joint portion 3 on the left and right end surfaces 13 and 14 of the core material 1. Although it can be appropriately set according to the gap Sp for absorbing an attachment error or the like, the thickness of the decorative sheet 20 itself, etc., for example, it may be about 50 μm to 1.0 mm. When it is provided with the decorative sheet 20 having a thickness of about 70 μm as in the present embodiment and is formed by excising the back side portion of the base material 22 of the surface material 2, it is about 0.1 mm. About 1.0 mm, more preferably about 0.2 mm to about 0.5 mm. By using the thin folding allowance 25 in this way, the elastic deformation can be easily performed without being hindered when bending into the gap Sp as described later.

また、上記折込み代２５の端部端面２２ｂからの延出幅は、適宜、設定可能であるが、表面材２，２が芯材１の左右端面１３，１４に貼着された状態で、対向される端部端面２２ｂ，２２ｂ間に形成される隙間Ｓｐに応じた延出幅とすればよい。つまり、該隙間Ｓｐを塞ぐようにして折込まれた折込み代２５，２５同士が弾接可能な延出幅とすればよい。また、この折込み代２５の延出幅は、後記するように左右端面１３，１４側に向けて屈曲された際に、これら左右端面１３，１４に当接しない程度のものとすることが好ましい。すなわち、延出幅を大きくし過ぎると、隙間Ｓｐに折込み弾接させた状態では、表面側に浮き上がる恐れがあるが、左右端面１３，１４に当接しない程度の延出幅とすれば、表面側に浮き上がるようなことを防止できる。   Further, the width of extension of the folding allowance 25 from the end face 22b can be appropriately set. What is necessary is just to set it as the extension width | variety according to the clearance gap Sp formed between end part end surface 22b, 22b. That is, the extension width 25 and the folding allowances 25 that are folded so as to close the gap Sp may be set so as to allow elastic contact. Further, it is preferable that the extending width of the folding allowance 25 is set so as not to contact the left and right end faces 13 and 14 when bent toward the left and right end faces 13 and 14 as described later. That is, if the extension width is excessively large, there is a risk of floating to the surface side in the state of being folded and elastically contacted with the gap Sp, but if the extension width is such that it does not contact the left and right end faces 13, 14, the surface It can be prevented from floating to the side.

また、上記隙間Ｓｐに応じて、上記表面材２の折曲用溝２４から端部端面２２ｂまでの幅寸法を設定するようにすればよい。すなわち、芯材１の左右端面１３，１４に貼着される表面材２，２の幅寸法は、貼着されて対向した際に、対向される端部端面２２ｂ，２２ｂ間に、上記した隙間Ｓｐが形成されるような幅寸法とすればよい。
尚、上記表面材２，２の対向する端部端面２２ｂ，２２ｂ間の隙間Ｓｐは、寸法誤差や取付誤差等を吸収可能な幅寸法とすればよく、１．０ｍｍ〜１０．０ｍｍ程度、２．０ｍｍ〜５．０ｍｍ程度としてもよい。これにより、後記するように、折込み代２５，２５が隙間Ｓｐに折込まれて該隙間Ｓｐを塞いだ際に、外観上、より目立ち難いものとなる。 Moreover, what is necessary is just to set the width dimension from the groove | channel 24 for bending of the said surface material 2 to the edge part end surface 22b according to the said clearance gap Sp. That is, the width dimension of the surface materials 2 and 2 adhered to the left and right end surfaces 13 and 14 of the core material 1 is the above-described gap between the opposed end end surfaces 22b and 22b when opposed to each other. The width dimension may be such that Sp is formed.
The gap Sp between the end portions 22b, 22b facing each other of the surface materials 2, 2 may be a width that can absorb a dimensional error, a mounting error, etc., and is about 1.0 mm to 10.0 mm. It is good also as about 0.0 mm-5.0 mm. As a result, as will be described later, when the folding margins 25 and 25 are folded into the gap Sp to close the gap Sp, the appearance is less noticeable.

上記構成とされた表面材２，２を、それぞれ芯材１に貼着する際には、図３（ｃ）に示すように、芯材１の表裏面１１，１２及び左右端面１３，１４を被装するように、これら表面材２，２を接着剤等によって貼着する。この際、図２（ａ）に示すように、上記折曲用溝２４に沿って表面材２を折り曲げ、当該折り曲げ部が、芯材１の表面１１と左右端面１３，１４との角部、裏面１２と左右端面１３，１４との角部に沿うように貼着する。また、これら左右端面１３，１４においては、図１（ｂ）に示すように、それぞれ表面側に貼着された表面材２と、裏面側に貼着された表面材２との端部端面２２ｂ，２２ｂが上記隙間Ｓｐを隔てて対向される。この隙間Ｓｐに、それぞれの折込み代２５，２５が、それぞれ左右端面１３，１４側に向けて屈曲されて折込まれるとともに、互いに弾接されて、これら折込み代２５，２５によって当該隙間Ｓｐを塞ぐようにして、繋ぎ目部３が形成される。   When the surface materials 2 and 2 having the above-described configuration are attached to the core material 1 respectively, the front and back surfaces 11 and 12 and the left and right end surfaces 13 and 14 of the core material 1 are attached as shown in FIG. The surface materials 2 and 2 are attached with an adhesive or the like so as to be covered. At this time, as shown in FIG. 2A, the surface material 2 is bent along the bending groove 24, and the bent portion is a corner portion between the surface 11 of the core material 1 and the left and right end faces 13, 14. It sticks along the corner | angular part of the back surface 12 and the right-and-left end surfaces 13 and 14. FIG. Moreover, in these right-and-left end surfaces 13 and 14, as shown in FIG.1 (b), the edge part end surface 22b of the surface material 2 stuck on the surface side and the surface material 2 stuck on the back surface side, respectively. , 22b are opposed to each other across the gap Sp. In the gap Sp, the folding margins 25 and 25 are bent and folded toward the left and right end surfaces 13 and 14, respectively, and are elastically contacted with each other, and the folding margins 25 and 25 close the gap Sp. In this way, the joint portion 3 is formed.

上記各部材を接着する接着剤としては、特に限定されず、ユリア樹脂や、メラミン樹脂、ユリア・メラミン共縮合樹脂、フェノール樹脂、エポキシ樹脂、ウレタン樹脂などの熱硬化性樹脂を含有する接着剤が挙げられる。あるいは、酢酸ビニル樹脂や、合成ゴム、ポリ乳酸、澱粉、アクリル樹脂等を含有する水性接着剤又はエマルジョン接着剤が挙げられる。あるいは、ポリプロピレンや、エチレン酢酸ビニル樹脂（ＥＶＡ）などの合成樹脂を含有するホットメルト接着剤などが挙げられる。   The adhesive for adhering each of the above members is not particularly limited, and an adhesive containing a thermosetting resin such as a urea resin, a melamine resin, a urea-melamine cocondensation resin, a phenol resin, an epoxy resin, or a urethane resin. Can be mentioned. Alternatively, an aqueous adhesive or an emulsion adhesive containing vinyl acetate resin, synthetic rubber, polylactic acid, starch, acrylic resin, and the like can be given. Alternatively, a hot melt adhesive containing a synthetic resin such as polypropylene or ethylene vinyl acetate resin (EVA) can be used.

上記折込み代２５，２５をそれぞれ左右端面１３，１４側に向けて屈曲させて折込み、互いに弾接させる態様は、どのような態様でもよく、例えば、表面材２，２を貼着する前に、それぞれの折込み代２５，２５を端部端面２２ｂ，２２ｂ側に折り曲げておいて、その状態で貼着するようにしてもよい。このような場合にも折込み代２５，２５は、上記したように弾性を有しているので、これら折込み代２５，２５の復元力により、互いに弾接して隙間Ｓｐを塞ぐことができる。或いは、貼着した後に、上記隙間Ｓｐに押し込むようにして屈曲させて折込んで、弾接させるようにしてもよい。   The above-described folding margins 25, 25 are bent toward the left and right end faces 13, 14, respectively, and may be folded in any manner. For example, before attaching the surface materials 2, 2, The folding margins 25 and 25 may be bent toward the end portion end faces 22b and 22b, and attached in that state. Even in such a case, since the folding margins 25 and 25 have elasticity as described above, the clearance Sp can be elastically contacted with each other by the restoring force of the folding margins 25 and 25 to close the gap Sp. Or after sticking, you may make it bend | fold and fold so that it may push in to the said clearance gap Sp, and you may make it elastically contact.

上記のように芯材１の表裏面１１，１２及び左右端面１３，１４に、それぞれ貼着された表面材２，２は、図１（ｂ）に示すように、左右端面１３，１４において、端部同士が対向されて、端部端面２２ｂ，２２ｂ間に形成された隙間Ｓｐに、それぞれの折込み代２５，２５が、当該隙間Ｓｐを塞ぐようにして、左右端面１３，１４側に向けて屈曲されて折込まれるとともに、互いに弾接されている。
上記状態では、これら折込み代２５，２５が、芯材１の左右端面１３，１４側に向けて屈曲されて折込まれているため、その表面側には、僅かな窪みが長手方向に沿って形成されることとなるが、互いに弾接された折込み代２５，２５の表面側への復元力により、当該窪みは微小なものとなる。すなわち、これら折込み代２５，２５は、互いに弾接されて表面側への復元力が作用しているので、互いに密着するようにして当該窪みを小さなものとでき、その表面側は、略面一となる。 As shown in FIG. 1B, the surface materials 2 and 2 adhered to the front and back surfaces 11 and 12 and the left and right end surfaces 13 and 14 of the core material 1 as described above, The ends are opposed to each other, and the respective folding margins 25 and 25 close to the gap Sp formed in the gap Sp formed between the end facets 22b and 22b toward the left and right end faces 13 and 14, respectively. They are bent and folded, and elastically contact each other.
In the above state, since the folding margins 25 and 25 are bent and folded toward the left and right end faces 13 and 14 of the core material 1, a slight depression is formed along the longitudinal direction on the surface side. However, due to the restoring force to the surface side of the folding allowances 25 and 25 that are elastically contacted with each other, the recess becomes minute. That is, since the folding allowances 25 and 25 are elastically contacted with each other and a restoring force to the surface side acts, the depressions can be made small so as to be in close contact with each other, and the surface side is substantially flush. It becomes.

以上のように、本実施形態に係る建築用パネル材１０は、寸法誤差や取付誤差等を吸収するために形成される表面材２，２の端部端面２２ｂ，２２ｂ間の繋ぎ目部３の隙間Ｓｐが、上記のように折込み代２５，２５によって塞がれて隠蔽されるので、意匠性を高めることができる。
特に、本実施形態では、芯材１の両側部の左右端面１３，１４において対向された表面材２，２の端部端面２２ｂ、２２ｂ間の上記隙間Ｓｐを、それぞれの端部の表面側部位から延出させた折込み代２５，２５によって塞ぐようにし、これら折込み代２５，２５が互いに弾接しているので、対向する表面材２，２のいずれの端部端面２２ｂ、２２ｂも当該折込み代２５，２５によって覆い隠され、意匠性に優れたものとなる。 As described above, the building panel material 10 according to the present embodiment has the joint portion 3 between the end facets 22b and 22b of the surface materials 2 and 2 formed to absorb dimensional errors and mounting errors. Since the gap Sp is closed and concealed by the folding margins 25 and 25 as described above, the design can be improved.
In particular, in the present embodiment, the gap Sp between the end portion end surfaces 22b and 22b of the surface materials 2 and 2 facing each other on the left and right end surfaces 13 and 14 on both sides of the core material 1 is defined as the surface side portion of each end portion. Since the folding allowances 25 and 25 are closed by the folding allowances 25 and 25, the end allowances 25 and 25 are in elastic contact with each other. , 25 and is excellent in design.

また、表面材２，２の折込み代２５，２５は、上記のように芯材１の左右端面１３，１４側に向けて屈曲されて折込まれているので、手前側（芯材１の左右端面１３，１４に対面した状態における手前側）に向けて突出するような段差が形成されず、意匠性に優れたものとなる。
さらに、上記折込み代２５，２５のそれぞれが芯材１の左右端面１３，１４側に向けて屈曲されて折込まれ、互いに弾接されているので、表面材２，２の端部端面が露出することがなく、剥がれ難いものとなる。 Moreover, since the folding margins 25 and 25 of the surface materials 2 and 2 are bent toward the left and right end surfaces 13 and 14 of the core material 1 as described above, the front side (the left and right end surfaces of the core material 1 is No step is formed so as to project toward the front side in the state facing 13 and 14, and the design is excellent.
Further, each of the folding margins 25, 25 is bent and folded toward the left and right end faces 13, 14 side of the core material 1, and is elastically contacted with each other, so that the end faces of the surface materials 2, 2 are exposed. It will be difficult to peel off.

さらにまた、上記のように隙間Ｓｐを塞ぐ部材を、折込み代２５，２５とし、当該折込み代２５，２５を、芯材１の左右端面１３，１４側に向けて屈曲させるとともに、互いに弾接させるようにしているので、表面材２，２の端部端面２２ｂ，２２ｂ間の隙間Ｓｐの幅寸法が長手方向に沿って均一ではない場合でも、これら折込み代２５，２５により、そのような誤差等も吸収でき、意匠性を高めることができる。
また、これにより、上記特許文献１に記載の扉パネルのように、当該隙間Ｓｐを所定幅寸法とするために切削等をする必要がないので、製造工程の簡略化が図れ、簡易な構造で隙間Ｓｐを隠蔽できる。
さらに、上記折込み代２５，２５は、表面材２，２の両端部の表面側部位を延出させたものとされているので、例えば、別部材等を、上記隙間Ｓｐに埋設するようなものと比べて、製造工程の簡略化が図れる。すなわち、表面材２，２の折込み代２５，２５を、芯材１の左右端面１３，１４側に向けて屈曲させ、弾接させることで、上記隙間Ｓｐを塞ぐことができ、製造工程の簡略化が図れ、簡易な構造で隙間Ｓｐを隠蔽できる。 Furthermore, the members that close the gap Sp as described above are the folding margins 25 and 25, and the folding margins 25 and 25 are bent toward the left and right end surfaces 13 and 14 side of the core member 1 and elastically contact each other. Therefore, even if the width dimension of the gap Sp between the end portions 22b and 22b of the surface materials 2 and 2 is not uniform along the longitudinal direction, such an error or the like due to the folding margins 25 and 25. Can be absorbed, and the design can be improved.
In addition, as in the door panel described in Patent Document 1, it is not necessary to perform cutting or the like in order to make the gap Sp a predetermined width, so that the manufacturing process can be simplified and the structure can be simplified. The gap Sp can be concealed.
Further, since the folding allowances 25 and 25 are formed by extending the surface side portions of both end portions of the surface materials 2 and 2, for example, another member or the like is embedded in the gap Sp. Compared with, the manufacturing process can be simplified. That is, by bending the folding margins 25 and 25 of the surface materials 2 and 2 toward the left and right end surfaces 13 and 14 of the core material 1 and elastically contacting them, the gap Sp can be closed, and the manufacturing process is simplified. The gap Sp can be concealed with a simple structure.

また、例えば、化粧シート２０の延出部２１のみを折込み代とする場合において、該化粧シート２０を基材２２の端部端面２２ｂから延出させるようにして基材２２の表面２２ａに貼着して折込み代を有する表面材２を形成する場合は、折込み代を構成する化粧シート２０の延出部２１の延出幅を略均一にする必要があることから、その貼着工程において高い精度が必要となる。一方、本実施形態のように、基材２２の裏面側部位を切除することにより折込み代２５，２５を形成するものとすれば、容易に、かつ精度良く折込み代２５，２５を形成することができる。また、このような裏面側部位の切除は、上記折曲用溝２４と同工程或いは関連した工程において実施できるので、上記のような化粧シート２０を基材２２の端部から延出させるようにして貼着するものと比べて、製造工程の簡略化が図られる。   Further, for example, when only the extending portion 21 of the decorative sheet 20 is used as the folding allowance, the decorative sheet 20 is attached to the surface 22a of the base material 22 so as to extend from the end face 22b of the base material 22. When the surface material 2 having a folding allowance is formed, it is necessary to make the extending width of the extending portion 21 of the decorative sheet 20 constituting the folding allowance substantially uniform. Is required. On the other hand, if the folding allowances 25 and 25 are formed by excising the back side portion of the base material 22 as in the present embodiment, the folding allowances 25 and 25 can be easily and accurately formed. it can. In addition, since the rear side portion can be cut in the same process as the bending groove 24 or in a related process, the decorative sheet 20 as described above is extended from the end of the base material 22. The manufacturing process can be simplified as compared with those that are attached.

次に、上記第１実施形態に係る建築用パネル材１０に適用される表面材の他例について、図４に基づいて説明する。図４（ａ）、（ｂ）は、いずれも建築用パネル材１０に適用される表面材の他例を示し、それぞれ図２（ｂ）に対応させた図である。図４（ａ）は、第１変形例に係る表面材、図４（ｂ）は、第２変形例に係る表面材を示している。
尚、上記例との相違点を中心に説明し、同様の構成については、同一符号を付し、その説明を省略或いは簡略に説明する。 Next, another example of the surface material applied to the building panel material 10 according to the first embodiment will be described with reference to FIG. 4 (a) and 4 (b) show other examples of the surface material applied to the building panel material 10, and correspond to FIG. 2 (b), respectively. FIG. 4A shows a surface material according to the first modification, and FIG. 4B shows a surface material according to the second modification.
Note that differences from the above example will be mainly described, and the same components will be denoted by the same reference numerals, and description thereof will be omitted or simplified.

第１変形例に係る表面材２Ａは、図４（ａ）に示すように、折込み代の構成が上記例の表面材２とは異なる。
すなわち、本変形例に係る表面材２Ａは、基材２２Ａの端部の裏面側部位を、上記例よりもやや薄く切除するようにしている。すなわち、化粧シート２０の延出部２１の裏面側に残す基材２２Ａの延出部２３Ａの厚さが、上記例よりも厚くなるように切除している。また、その基材２２Ａの延出部２３Ａの基端部には、屈曲させて折込む際に容易に折込めるように、凹溝状の溝部２６が長手方向（縦方向）に沿って設けられている。 As shown in FIG. 4A, the surface material 2A according to the first modification differs from the surface material 2 of the above example in the configuration of the folding margin.
That is, the surface material 2A according to the present modification is cut slightly thinner than the above example at the back side of the end portion of the base material 22A. That is, it cuts out so that the thickness of extension part 23A of substrate 22A left on the back side of extension part 21 of decorative sheet 20 may become thicker than the above-mentioned example. Further, a groove-like groove portion 26 is provided along the longitudinal direction (longitudinal direction) at the base end portion of the extending portion 23A of the base material 22A so as to be easily folded when folded. ing.

すなわち、上記例の表面材２及び本変形例に係る表面材２Ａにおいては、いずれも折込み代２５，２５Ａの形成を、表面材２，２Ａの端部の裏面側部位を切除することにより形成するようにしている。従って、当該折込み代２５，２５Ａの厚さを容易に調整することができる。よって、化粧シート２０が比較的薄い場合等で、折込み代２５，２５Ａの強度を高めたい場合には、上記裏面側部位を切除する厚さを調整することで、折込み代２５，２５Ａの強度を容易に高めることができる。   That is, in the surface material 2 of the above example and the surface material 2A according to the present modification, the folding margins 25 and 25A are both formed by cutting away the back surface side portions of the end portions of the surface materials 2 and 2A. I am doing so. Therefore, the thickness of the folding allowances 25 and 25A can be easily adjusted. Therefore, when the decorative sheet 20 is relatively thin, etc., and when it is desired to increase the strength of the folding margins 25 and 25A, the strength of the folding margins 25 and 25A is adjusted by adjusting the thickness for cutting away the back side portion. Can be easily increased.

図７（ａ）、（ｂ）は、いずれも第４実施形態に係る建築用パネル材を示し、（ａ）は、図１（ａ）に対応させた図、（ｂ）は、図２（ａ）に対応させた図である。
尚、上記第１実施形態との相違点を中心に説明し、同様の構成については、同一符号を付し、その説明を省略あるいは簡略に説明する。 Next, still another embodiment according to the present invention will be described with reference to the drawings.
FIGS. 7 (a) and 7 (b) each show a building panel material according to the fourth embodiment, (a) is a diagram corresponding to FIG. 1 (a), and (b) is FIG. It is a figure corresponding to a).
Note that differences from the first embodiment will be mainly described, and the same components will be denoted by the same reference numerals, and description thereof will be omitted or simplified.

本実施形態に係る建築用パネル材１０Ｃは、芯材１の外表面に貼着される表面材２Ｆ，２Ｇの構成が上記第１実施形態とは異なる。
すなわち、本実施形態では、芯材１の左右端面１３，１４（図３も参照）においてそれぞれ対向される二枚の表面材２Ｆ，２Ｇのうち、一方の表面材２Ｆの両端部（図では一方の端部のみを図示している）にのみ、上記同様の表面側部位を延出させた折込み代２５Ｃをそれぞれ形成している。つまり、他方の表面材２Ｇの両端部（図では一方の端部のみを図示している）には、折込み代が形成されていない。
また、これら表面材２Ｆ，２Ｇは、いずれも上記同様の基材２２Ｆ，２２Ｇと、これら基材２２Ｆ，２２Ｇにそれぞれ貼着された上記同様の化粧シート２０，２０とからなり、これら基材２２Ｆ，２２Ｇの裏面には、上記同様の角部において折り曲げ可能なように形成された折曲用凹条部２４Ａが形成されている。この折曲用凹条部２４Ａは、本実施形態では、上記折曲用溝２４とは異なり、長手方向に沿って形成された断面略Ｖ字状の複数本の凹条からなり、折り曲げられた際には、その表面側が、図７（ａ）に示すように、Ｒ形状となる構成とされている。 The construction panel material 10C according to the present embodiment is different from the first embodiment in the configuration of the surface materials 2F and 2G attached to the outer surface of the core material 1.
In other words, in the present embodiment, both end portions of one surface material 2F (one in the figure, one of the two surface materials 2F and 2G facing each other on the left and right end surfaces 13 and 14 of the core material 1 (see also FIG. 3)). Only the end portion of FIG. 2 is formed), and the folding margin 25C is formed by extending the surface side portion similar to the above. That is, no folding margin is formed at both ends of the other surface material 2G (only one end is shown in the figure).
Each of the surface materials 2F and 2G includes the same base materials 22F and 22G as described above, and the same decorative sheets 20 and 20 attached to the base materials 22F and 22G, respectively. , 22G is formed with a concave groove 24A for bending, which is formed so that it can be bent at the same corner as described above. In this embodiment, unlike the bending groove 24, the bending recess 24A is composed of a plurality of recesses having a substantially V-shaped cross section formed along the longitudinal direction and bent. In this case, the surface side has an R shape as shown in FIG.

前記構成とされた表面材２Ｆ，２Ｇは、上記第１実施形態と同様にして、芯材１の表裏面１１，１２及び左右端面１３，１４に貼着される。
貼着された状態では、図７（ａ）に示すように、表面側に貼着された表面材２Ｆの端部端面２２ｂと、裏面側に貼着された表面材２Ｇの端部端面２２ｂとが上記同様の隙間Ｓｐ（図１（ｂ）参照）を隔てて対向されている。また、上記表面側に貼着された表面材２Ｆの両端部に形成された折込み代２５Ｃ，２５Ｃを、それぞれ芯材１の左右端面１３，１４側に向けて屈曲させ、折込むとともに、裏面側に貼着された表面材２Ｇの端部端面２２ｂ，２２ｂに弾接させて、上記隙間Ｓｐを塞ぐようにして、繋ぎ目部３Ａが形成される。 The surface materials 2F and 2G configured as described above are attached to the front and back surfaces 11 and 12 and the left and right end surfaces 13 and 14 of the core material 1 in the same manner as in the first embodiment.
In the state of being attached, as shown in FIG. 7 (a), the end portion end face 22b of the surface material 2F attached to the front surface side, and the end portion end face 22b of the surface material 2G attached to the back surface side, Are opposed to each other with a gap Sp (see FIG. 1B) similar to the above. Further, the folding margins 25C and 25C formed at both ends of the surface material 2F attached to the front surface side are bent toward the left and right end surfaces 13 and 14 side of the core material 1, respectively, and folded, and the back surface side 3A of joint parts are formed so that it may be elastically contacted by the edge part end surfaces 22b and 22b of the surface material 2G stuck on, and the said gap Sp may be plugged up.

以上のように本実施形態に係る建築用パネル材１０Ｃによれば、上記第１実施形態と同様、製造工程の簡略化が図れるとともに、寸法誤差や取付誤差等を吸収するために形成される表面材２Ｆ，２Ｇの端部同士の隙間Ｓｐ（図１（ｂ）参照）が、折込み代２５Ｃによって塞がれるので、当該隙間Ｓｐが目立ち難くなり、意匠性を高めることができる。
また、表面材２Ｆ，２Ｇのうち、表面材２Ｆの両端部に形成された折込み代２５Ｃは、上記のように芯材１の左右端面１３，１４側に向けて屈曲されて折込まれているので、手前側（パネル芯材１の左右端面１３，１４に対面した状態における手前側）に向けて突出するような段差が形成されず、意匠性に優れたものとなる。また、手前側に向けて突出するような段差が形成されないので、上述のような芯材の端面において化粧シートを重ねるものと比べて、剥がれ難いものとなる。また、該表面材２Ｆ，２Ｇの端部は、芯材１の左右端面１３，１４において対向されているので、上述のようなエッジシートを貼着するものと比べて、剥がれ難いものとなる。 As described above, according to the building panel material 10C according to the present embodiment, as in the first embodiment, the manufacturing process can be simplified, and the surface formed to absorb dimensional errors, mounting errors, and the like. Since the gap Sp between the ends of the materials 2F and 2G (see FIG. 1B) is closed by the folding allowance 25C, the gap Sp becomes inconspicuous and the design can be improved.
Further, among the surface materials 2F and 2G, the folding margin 25C formed at both ends of the surface material 2F is bent and folded toward the left and right end surfaces 13 and 14 of the core material 1 as described above. , A step projecting toward the front side (the front side in a state facing the left and right end surfaces 13 and 14 of the panel core 1) is not formed, and the design is excellent. Moreover, since the level | step difference which protrudes toward this side is not formed, it becomes a thing which is hard to peel compared with what overlaps a decorative sheet in the end surface of the above core materials. Moreover, since the edge part of this surface material 2F and 2G is opposed in the right-and-left end surfaces 13 and 14 of the core material 1, it becomes a thing which is hard to peel compared with what sticks the above edge sheets.
