Description

本発明は、外壁の出隅部構造および出隅処理方法に関する。   The present invention relates to a protruding corner structure of an outer wall and a protruding corner processing method.

住宅等の建物の外壁がサイディング等の外壁材を用いて施工される場合、通常、所定の規格サイズのもとで板状に形成された多数枚の外壁材を、胴縁等を介して柱等の構造材に固定されている。また、このような外壁の出隅部には、その角部形状に合わせて別途形成された出隅部材や出隅柱が用いられていることが多い。   When the outer wall of a building such as a house is constructed using an outer wall material such as siding, a large number of outer wall materials that are formed in a plate shape under a predetermined standard size are usually used as pillars through the trunk edge, etc. It is fixed to structural materials such as. In addition, a protruding corner member or a protruding corner column that is separately formed according to the shape of the corner is often used for the protruding corner of the outer wall.

例えば、出隅部材は、所定規格のもとで形成された１枚の板状外壁材を、その中央部で切断して２枚の基材が形成される。そして、施工する出隅部が直角状であれば、基材の端部をそれぞれ外壁材の厚み方向に対して４５°の角度で切断して突き合わせ端面を形成し、接着剤を塗布して突き合わせ端面同士が接着される。これにより、出隅部材は略直角状に突き合わせられ、外壁の出隅部の形状をなすように形成されていた。   For example, the protruding corner member is formed by cutting one plate-like outer wall material formed according to a predetermined standard at the center thereof to form two substrates. And if the projecting corner to be constructed is right-angled, the end of the base material is cut at an angle of 45 ° with respect to the thickness direction of the outer wall material to form a butt end face, and the butt is applied by applying an adhesive. The end faces are bonded together. Accordingly, the protruding corner member is abutted at a substantially right angle, and is formed to have the shape of the protruding corner portion of the outer wall.

この種の出隅部材または出隅柱として、特許文献１には、２枚の平板状の窯業系板片を突き合わせ、形成された出隅の頂部に面取り部を設ける構成が提案されている。面取り部は、意匠面側に部分的に設けられた凹部のある部分においては、面取り部と裏側角部との距離が小さく形成され、面取り部の幅を一定にして外観の意匠性に配慮することが意図されている。   As this kind of protruding corner member or protruding corner column, Patent Document 1 proposes a configuration in which two flat ceramic board pieces are abutted and a chamfered portion is provided at the top of the formed protruding corner. The chamfered part is formed with a small distance between the chamfered part and the back side corner part in a part having a concave part provided partially on the design surface side, and the width of the chamfered part is made constant to give consideration to the design of the appearance. Is intended.

また、特許文献２には、サイディングの接合面にあらかじめ切欠を設けて入隅用サイディングと出隅用サイディングとを形成し、直角をなして連結できるようにしておくとともに、あらかじめ出隅用サイディングの端部を面取りしている構成が記載されている。   Further, in Patent Document 2, a notch is provided in advance in the joint surface of the siding to form a corner siding and a corner siding so that they can be connected at a right angle. A configuration with chamfered ends is described.

特許文献３にも、外装材の端面同士を接着して、接着部を跨ぐように面取りした構成が記載されており、さらに出隅面取り部の表面に、シーラー、パテ、上塗り塗料を順に塗布して、塗装層にクラックを発生させないようにすることが提案されている。
特開平９−１５８４３７号公報 特開平８−３２６２６５号公報 特開２００４−１４８１４１号公報 Patent Document 3 also describes a configuration in which the end surfaces of the exterior material are bonded to each other and chamfered so as to straddle the bonded portion. Therefore, it has been proposed to prevent cracks in the paint layer.
JP-A-9-158437 JP-A-8-326265 JP 2004-148141 A

しかしながら、前記従来例の出隅部材では、いずれも面取り部が外壁材の室外側表面に対して４５°の角度で面取りして形成されている。このように、面取り部が４５°の平削りであると、面取り部の幅が大きくなって目立ちやすく、出隅部における良好な外観を確保できないという問題点があった。特に、外壁材表面の模様が大きいものほど、あるいは模様溝の深さが深く形成されているのものほど、その模様の底部（溝底部）まで削り取る必要があって面取り量を多くせざるを得ないため、必然的に面取りする面の幅が拡がってしまっていた。   However, in each of the conventional corner members of the conventional example, the chamfered portion is formed by chamfering at an angle of 45 ° with respect to the outdoor surface of the outer wall material. As described above, when the chamfered portion is 45 ° flattened, the width of the chamfered portion becomes large and is easily noticeable, and there is a problem that a good appearance at the protruding corner portion cannot be secured. In particular, the larger the pattern on the surface of the outer wall material, or the deeper the pattern groove is, the more the chamfering amount must be increased because the bottom of the pattern (groove bottom) needs to be scraped off. As a result, the width of the chamfered surface inevitably increased.

面取り部の幅が大きくなると、その中央部に、２枚の外壁材の繋ぎ目である接合面のラインが現れ、また外壁材の表面化粧層と、内部の基板層との質感および色調の違いが露出し、非常に見栄えが悪くなる。   When the width of the chamfered portion increases, a line of the joint surface, which is a joint between the two outer wall materials, appears in the center, and the texture and color difference between the surface decorative layer of the outer wall material and the internal substrate layer Is exposed and looks very bad.

また、あらかじめ４５°に面取りした基材同士を突き合わせて出隅部を形成する場合には、接合面に接着剤を塗ってこれらを接合するのに互いにずれてしまったり、接着剤が接合面からはみ出たりして、所望の状態で接合することが難しく、その後処理も煩雑になってしまう問題点があった。   In addition, in the case of forming the protruding corner portion by abutting substrates that have been chamfered at 45 ° in advance, the joint surfaces may be offset from each other when an adhesive is applied to join the joint surfaces. It has a problem that it protrudes and is difficult to join in a desired state, and the subsequent processing becomes complicated.

一方で、出隅部において面取りをせずに処理しようとすると、見栄えの問題は解消しうるが、接合面を挟んで模様が連続するように意匠目地ピッチを合わせて接合したり、接合面からはみ出した接着剤を取り除いたりする作業が必要になって、手間がかかり、かえって生産性に劣るという問題点があった。   On the other hand, when trying to process without chamfering at the corners, the appearance problem can be solved, but the design joint pitch is adjusted so that the pattern is continuous across the joint surface, or from the joint surface There is a problem that it is necessary to remove the protruding adhesive, which takes time and is inferior in productivity.

そこで本発明は、上記のような問題点にかんがみてなされたものであり、作業工程を煩雑にすることなく、パネル基材に形成されている表面模様の連続性を保持しつつ、外壁の出隅部における美観を向上させることのできる外壁の出隅部構造および出隅処理方法を提供するものである。   Therefore, the present invention has been made in view of the above-described problems, and the continuity of the surface pattern formed on the panel base material is maintained without complicating the work process, and the outer wall protrudes. It is an object of the present invention to provide a protruding corner structure of an outer wall and a protruding corner processing method that can improve the appearance at the corner.

上記した目的を達成するため、本発明は、室外側表面に溝模様が形成された少なくとも２枚のパネル基材の端部同士が略Ｌ字状に突き合わせて接着され、出隅処理がなされた出隅部を備える外壁の出隅部構造であって、前記出隅部は、削り取り面が室内側に凹状に窪み、かつ、溝模様の溝深さＤの２倍以下の長さとなる面取り幅Ｗで面取りされ、前記削り取り面は、溝模様の溝形状に対応する形状であるとともに、厚み方向には溝模様の溝深さＤに対応する位置まで削り取られていることを特徴とする。 In order to achieve the above-described object, in the present invention, the ends of at least two panel base materials each having a groove pattern formed on the outdoor surface are abutted in a substantially L shape and bonded to each other , and the corner treatment is performed. A projecting corner structure of an outer wall provided with a projecting corner, wherein the projecting corner has a chamfered width in which a shaving surface is recessed concavely on the indoor side and has a length not more than twice the groove depth D of the groove pattern. It is chamfered with W, and the scraped surface has a shape corresponding to the groove shape of the groove pattern, and is cut to a position corresponding to the groove depth D of the groove pattern in the thickness direction .

ここで、前記面取り幅とは、面取りした出隅部の削り取り面における稜線間隔で規定される幅をいい、パネル基材同士の接合面の配置方向に、削り取り面を投影した場合の投影幅を指すものとする。   Here, the chamfered width refers to a width defined by a ridge line interval in the chamfered surface of the chamfered corner, and the projected width when the chamfered surface is projected in the arrangement direction of the joint surface between the panel base materials. Shall point to.

この発明により、パネル基材に形成されている溝模様の溝底まで削りつつも、面取り幅を溝深さの２倍以下の長さに相当する範囲内で形成することができ、施された出隅処理を目立たせることなく、美しい外観を保持することができる。また、パネル基材同士を突き合わせて接着後に出隅処理をすればよいので、接着面から接着剤がはみ出して硬化していても削り取って除去することができ、作業性が高められる。さらに、削り取り面は室内側に凹状に窪んで形成されるので、接合面のラインや色調の違い等が室外側に露出しにくく、外観意匠性を高めることができる。   According to the present invention, while chamfering to the groove bottom of the groove pattern formed on the panel base material, the chamfer width can be formed within a range corresponding to a length equal to or less than twice the groove depth. A beautiful appearance can be maintained without conspicuous the corner treatment. Moreover, since it is only necessary to perform the corner treatment after the panel base materials are brought into contact with each other, even if the adhesive protrudes from the adhesive surface and is cured, it can be scraped off and the workability can be improved. Further, since the scraped surface is formed in a concave shape on the indoor side, the line of the joint surface, the difference in color tone and the like are not easily exposed to the outdoor side, and the appearance design can be improved.

また、前記構成の外壁の出隅部構造において、前記出隅処理は、断面略Ｖ字形状に面取りが施されていることを特徴とする。あるいは、前記出隅処理は、断面略Ｕ字形状に面取りが施されてもよく、また、断面略円弧状に面取りが施されてもよい。   Moreover, in the protruding corner structure of the outer wall having the above-described configuration, the protruding corner processing is characterized in that chamfering is performed in a substantially V-shaped cross section. Alternatively, the protruding corner process may be chamfered to have a substantially U-shaped cross section, or may be chamfered to have a substantially arc-shaped cross section.

このような出隅処理により、出隅部における削り取り面を溝模様の溝形状に合わせて形成したり、建物に応じた好ましい意匠に形成したりすることが可能になる。また、これらの削り取り面の面取り形状は、用いる切削工具の刃形状を変えることで対応し得るので、別途新たな切削設備を必要とせず、現行のままの作業工程で、生産性よく形成することができる。   By such a corner treatment, it is possible to form the cut surface at the corner to match the groove shape of the groove pattern, or to form a preferred design according to the building. In addition, since the chamfered shape of these cutting surfaces can be dealt with by changing the blade shape of the cutting tool to be used, a new cutting equipment is not required and it can be formed with high productivity in the current work process. Can do.

また、上記目的を達成するため、本発明に係る外壁の出隅処理方法は、室外側表面に溝模様を有する少なくとも２枚のパネル基材の端部同士を略Ｌ字状に突き合わせ、接着することにより出隅部を形成し、当該出隅部に切削工具を用いて出隅処理を施す外壁の出隅処理方法であって、前記出隅部に、溝模様の溝深さＤの２倍以下の長さとなる面取り幅Ｗで、かつ、削り取り面を室内側に凹状に窪ませて面取りを施し、前記面取りは、溝模様の溝形状に対応する断面形状とするとともに、パネル基材の厚み方向には溝模様の溝深さＤに対応する位置まで削り取ることを特徴とする。また、かかる構成において、前記出隅部を略Ｖ字形状、略Ｕ字形状、又は略円弧状の断面形状に面取りすることが好ましい。 In order to achieve the above object, external corner processing method of the outer wall of the present invention, butt ends of at least two panels substrate having a groove pattern on the exterior side surface in a substantially L shape is bonded forming a external corner portion by, a external corner processing method of the outer wall subjected to external corner processing using the cutting tool on the external corner portion, on the external corner portions, 2 times the groove depth D of the groove pattern the following lengths become chamfer width W, and recessed in a concave scraping surface to the indoor side beveled with the chamfer is adapted to the cross-sectional shape corresponding to the groove shape of the groove pattern, the thickness of the panel substrate characterized Rukoto Kezurito to a position corresponding to the groove depth D of the groove pattern in the direction. In this configuration, it is preferable that the protruding corner is chamfered to have a substantially V-shaped, substantially U-shaped, or substantially arc-shaped cross-sectional shape.

この発明により、作業工程を煩雑にすることなく前記出隅部構造を容易に形成でき、表面模様の連続性を保持しつつ、外観意匠性を高めた出隅部構造を実現することが可能になる。   According to the present invention, it is possible to easily form the protruding corner structure without complicating the work process, and it is possible to realize a protruding corner structure with improved appearance design while maintaining the continuity of the surface pattern. Become.

前記のように特徴づけられる本発明の外壁の出隅部構造および出隅処理方法によれば、出隅部の製造ラインにおいて作業工程を煩雑にすることなく、パネル基材に形成された表面模様の連続性を保持しつつ、外観意匠性を高めて納まりよく出隅部を形成することが可能である。   According to the projected outer corner structure and the projected corner processing method of the present invention characterized as described above, the surface pattern formed on the panel base material without complicating the work process in the projected corner manufacturing line. While maintaining the continuity, the appearance design can be improved and the protruding corner can be formed well.

以下、本発明に係る外壁の出隅部構造および出隅処理方法を実施するための最良の形態について、図面を参照しつつ説明する。   DESCRIPTION OF THE PREFERRED EMBODIMENTS The best mode for carrying out an outer corner structure and an outer corner processing method according to the present invention will be described below with reference to the drawings.

図１は本発明に係る外壁の出隅部構造を示す斜視図、図２〜図３は出隅部の実施例を示す断面図である。また、図５（ａ），（ｂ）は本発明に係る出隅処理方法をそれぞれ模式的に示す説明図である。 FIG. 1 is a perspective view showing a protruding corner structure of an outer wall according to the present invention, and FIGS. 2 to 3 are sectional views showing an embodiment of the protruding corner. FIGS. 5A and 5B are explanatory views schematically showing the projected corner processing method according to the present invention.

なお、本実施形態の説明において示した各断面図では、出隅部構造を見やすくするために、断面を示すハッチングを省略して記載している。 In each sectional view shows Te described smell of this embodiment, for the convenience of external corner portion structure are described with hatching indicating the cross section.

本発明において、建物の外壁仕上に用いられるパネル基材１は、例えば、セメント系、セラミック系等の平板状のサイディング材であり、室外側表面に縦横の一方あるいは双方に溝が設けられて凹凸状の外壁意匠を構成する溝模様が形成されている。この溝模様における溝深さＤは、平均して５ｍｍ〜１０ｍｍ程度で形成されており、例示の形態では、この溝深さが７ｍｍのものについて示している。   In the present invention, the panel base material 1 used for finishing the outer wall of a building is a flat siding material such as cement or ceramic, and is provided with grooves on one or both of the vertical and horizontal sides on the outdoor surface. A groove pattern constituting the outer wall design is formed. The groove depth D in this groove pattern is formed with an average of about 5 mm to 10 mm, and in the illustrated embodiment, the groove depth is 7 mm.

建物の出隅部１０は、このようなパネル基材１，１の端部同士を略Ｌ字状に突き合わせて接着することにより形成されている。出隅部１０を形成するにあたり、突き合わせるパネル基材１の側端部は、その厚み方向に対して４５°の角度で斜めに切断されて、接合面２が形成されている。   The corner 10 of the building is formed by abutting and bonding the end portions of such panel base materials 1 and 1 in a substantially L shape. In forming the protruding corner portion 10, the side end portion of the panel base member 1 to be abutted is cut obliquely at an angle of 45 ° with respect to the thickness direction to form the joint surface 2.

パネル基材１の接合面２には接着剤が塗布され、同様の接合面２が形成された別のパネル基材１と、互いに直角をなすように略Ｌ字状に接着される。このとき、パネル基材１の室外側表面の溝模様を、接合面２を挟んで連続するように揃えなくともよい。また、突き合わせた接合面２から接着剤がはみ出さないようにする必要もなく、はみ出た接着剤が出隅部１０の室外側で硬化してもよい。   An adhesive is applied to the bonding surface 2 of the panel base material 1 and is bonded to another panel base material 1 on which the similar bonding surface 2 is formed in a substantially L shape so as to be perpendicular to each other. At this time, the groove pattern on the outdoor surface of the panel substrate 1 does not need to be aligned so as to be continuous with the joint surface 2 interposed therebetween. Moreover, it is not necessary to prevent the adhesive from protruding from the joined surface 2, and the protruding adhesive may be cured on the outdoor side of the protruding corner portion 10.

このように形成された出隅部１０には、出隅処理が施される。出隅処理は、溝模様の溝深さＤ（この場合は７ｍｍ）に応じて適宜の面取り幅Ｗで面取りすることによりなされる。また、かかる面取りは切削工具４を用いて行われるが、刃形状が略凸状の切削工具４を用いて、出隅部１０には室内側に凹状に窪んだ削り取り面３が形成される。このとき、接合面２から接着剤がはみ出て硬化した箇所も一緒に除去することができる。   The protruding corner portion 10 thus formed is subjected to a protruding corner process. The protruding corner processing is performed by chamfering with an appropriate chamfering width W according to the groove depth D (7 mm in this case) of the groove pattern. Further, the chamfering is performed using the cutting tool 4, but the cutting surface 3 having a concave shape on the indoor side is formed in the protruding corner portion 10 using the cutting tool 4 having a substantially convex blade shape. At this time, the portion where the adhesive protrudes from the joint surface 2 and is cured can be removed together.

切削工具４は、図５（ａ）に示すように断面略Ｖ字状、あるいは同図（ｂ）に示すように断面略Ｕ字状の刃形状のものを選択する。これにより、出隅部１０に、図２に示したような断面略Ｖ字形状、あるいは図３に示したような断面略Ｕ字形状に窪んだ削り取り面３をそれぞれ設けることができる。また、切削工具４の刃形状を、より大きな曲面を有するものに変えて、図４に示すように、さらに曲面の浅い断面略円弧状の削り取り面３を形成してもよい。   The cutting tool 4 is selected to have a blade shape having a substantially V-shaped cross section as shown in FIG. 5A or a substantially U-shaped cross section as shown in FIG. As a result, it is possible to provide the cut-out surface 3 which is recessed in the substantially V-shaped cross section as shown in FIG. 2 or the substantially U-shaped cross section as shown in FIG. Further, the cutting shape of the cutting tool 4 may be changed to one having a larger curved surface to form a scraped surface 3 having a further curved surface having a substantially arcuate shape as shown in FIG.

切削工具４の刃形状は、パネル基材１に形成されている溝模様の溝形状に近いものを選択することが好ましい。すなわち、図１に示したように、パネル基材１の溝模様の溝形状が断面略台形状であれば、切削工具４に断面略Ｖ字状の刃形状のものを選択することが好ましい。これにより、例示するような断面略Ｖ字形状の削り取り面３を形成することができ、外観上、溝模様の連続性を絶つことなく、削り取り面３の目立ちにくい出隅部１０を構成することが可能になる。   The blade shape of the cutting tool 4 is preferably selected to be close to the groove shape of the groove pattern formed on the panel substrate 1. That is, as shown in FIG. 1, if the groove shape of the groove pattern of the panel base material 1 is a substantially trapezoidal cross section, it is preferable to select a cutting tool 4 having a substantially V-shaped blade shape. As a result, the scraped surface 3 having a substantially V-shaped cross section as illustrated can be formed, and the appearance corner portion 10 of the scraped surface 3 that is less noticeable is formed without continuity of the groove pattern in appearance. Is possible.

図６（ａ）は、前記断面略Ｖ字形状に面取りした場合の削り取り面３を示す外壁の断面図である。また、図６（ｂ）は、この実施形態の比較例として、従来の出隅部の削り取り面を示す断面図であり、図７は従来の出隅部を示す斜視図である。   FIG. 6A is a cross-sectional view of the outer wall showing the scraped surface 3 when chamfered to have a substantially V-shaped cross section. FIG. 6B is a cross-sectional view showing a conventional scraped surface of the protruding corner as a comparative example of this embodiment, and FIG. 7 is a perspective view showing the conventional protruding corner.

本発明においては、出隅処理の削り取り面３が、溝模様の溝深さＤの２倍以下の長さとなる面取り幅Ｗで形成されている。ここで、面取り幅Ｗとは、図６（ａ）に示すように、出隅処理により形成する削り取り面３における稜線間隔で規定される幅をいう。したがって、例示の形態では、溝深さＤが７ｍｍであるので、１４ｍｍ以下の長さの面取り幅Ｗで面取りすることが好ましく、断面が１２０°の略Ｖ字形状となっているので、面取り幅Ｗは約１２．６ｍｍで形成されることになる。   In the present invention, the cut-out surface 3 for the projected corner process is formed with a chamfer width W that is not more than twice the groove depth D of the groove pattern. Here, the chamfering width W refers to a width defined by a ridge line interval in the shaving surface 3 formed by the protruding corner process, as shown in FIG. Therefore, in the illustrated embodiment, since the groove depth D is 7 mm, it is preferable to chamfer with a chamfering width W having a length of 14 mm or less, and since the cross section has a substantially V shape with a 120 ° section, the chamfering width is W will be formed at about 12.6 mm.

これに対し、図６（ｂ）に比較例として示す従来の出隅部９では、溝深さｄが同じ７ｍｍであるのに対して、約１９．８ｍｍの面取り幅ｗの面づらが形成される。すなわち、図７に示すように、従来の出隅部９の削り取り面９１は、本発明における削り取り面３（図１参照）に比べてその幅が非常に大きくなり、目立ちやすいものとなっている。したがって、本発明の出隅処理方法によって、面取り幅Ｗを比較的小さく構成して、外観にもたらす意匠上の影響を最小限に抑えつつ、美しい納まりを形成することができるものとなっている。   On the other hand, in the conventional protruding corner portion 9 shown as a comparative example in FIG. 6B, the groove depth d is 7 mm, which is the same as that of the chamfer width w of about 19.8 mm. The That is, as shown in FIG. 7, the scraped surface 91 of the conventional protruding corner portion 9 has a much larger width than the scraped surface 3 (see FIG. 1) in the present invention, and is easily noticeable. . Therefore, with the projected corner processing method of the present invention, the chamfer width W can be configured to be relatively small, and a beautiful space can be formed while minimizing the influence of the design on the appearance.

以上のように、本発明では、建物における出隅部１０を、作業工数を増やすことなく、あらかじめ工場で製造することができ、施工現場においては建物の外壁面の他の部分と同様に、パネル基材１を用いて構成した出隅部部材を設置するだけで済み、優れた施工性で納まりよく出隅部１０を形成することができる。また、かかる出隅部構造および出隅処理方法によれば、形成された出隅部１０の削り取り面３が目立ちにくく、パネル基材１の室外側表面に形成された溝模様の意匠性を殺すことなく、模様を連続させて見せる効果をもたらすことができる。   As described above, in the present invention, the protruding corner portion 10 in the building can be manufactured in advance in the factory without increasing the number of work steps, and at the construction site, the panel is the same as other portions on the outer wall surface of the building. It is only necessary to install a protruding corner member constituted by using the base material 1, and the protruding corner portion 10 can be formed well with excellent workability. Further, according to the protruding corner structure and the protruding corner processing method, the scraped surface 3 of the formed protruding corner 10 is not conspicuous, and the design of the groove pattern formed on the outdoor surface of the panel substrate 1 is killed. The effect of showing the pattern continuously can be brought about.

したがって、施工される建物において、外観上の統一感をもたせて所望の意匠性を実現することができ、多用な表現に対応した外壁を形成することが可能になる。   Therefore, in the building to be constructed, it is possible to achieve a desired design property with a uniform appearance and to form an outer wall corresponding to various expressions.

本発明は、住宅等の建物における外壁の出隅部を納まりよく構成するのに好適に利用することができる。   INDUSTRIAL APPLICABILITY The present invention can be suitably used to form a well-contained outer corner of an outer wall in a building such as a house.
