本発明は、住宅等の建物の外壁を構成する外壁材およびこの外壁材を使用した外壁構造に関する。   The present invention relates to an outer wall material constituting an outer wall of a building such as a house and an outer wall structure using the outer wall material.

丸太材を複数本並設した様な仕上がり外観が得られるログハウス調の外壁材の一例として特許文献１に記載のものが知られている。
この特許文献１に記載の外壁材は、繊維板の表面に断面略円弧状で長手方向の凸脈を複数脈相互に隣接させて並設し、該表面に凸脈に沿って木質薄単板を貼着してなるものである。
この外壁材を製造する場合、繊維板の表面に接着剤を介して木質薄単板を貼着する際に、プレス面に断面略円弧状で長手方向の凹脈が複数脈相互に隣接して並設された熱圧プレスの同プレス面を木質薄単板上に圧接させている。 The thing of patent document 1 is known as an example of the log-house-like outer wall material from which the finished external appearance like multiple log | wood members arranged in parallel is obtained.
The outer wall material described in Patent Document 1 is provided with a plurality of longitudinally protruding ridges adjacent to each other on the surface of a fiber board in a substantially arc-shaped cross section, and a thin wooden board along the protruding ridges on the surface. Is attached.
When manufacturing this outer wall material, when sticking a thin wood veneer to the surface of the fiberboard via an adhesive, a plurality of concave veins in the longitudinal direction and adjacent to each other have a substantially arc-shaped cross section on the press surface. The press surface of the hot-pressing presses placed side by side is pressed onto a thin wood veneer.

そして、上記のような外壁材では、表面は木質薄単板で構成されているので、ログハウス調の良好な外観に仕上がり、又、各凸脈間に隙間が発生することもない。
また、熱圧プレスによって繊維板の表面に木質薄単板が貼着されると同時にこの表面にプレス面の凹脈に対応する複数の凸脈を形成できる。
特開平８−３９５１０号公報 In the outer wall material as described above, the surface is composed of a thin wood single plate, so that it has a good log house-like appearance, and there is no gap between the convex veins.
Further, a thin wooden plate is stuck on the surface of the fiberboard by hot pressing, and at the same time, a plurality of convex veins corresponding to the concave veins of the press surface can be formed on this surface.
JP-A-8-39510

ところが、前記従来の外壁材は、繊維板の表面に断面略円弧状で長手方向の凸脈を複数脈相互に隣接させて並設し、該表面に凸脈に沿って木質薄単板を貼着したものであるため、繊維板と木質薄単板という２種類の材料を必要とし、しかもこれらを接着剤によって貼着するため、材料のコストが高くなるとともに、製造に手間がかかるという課題があった。   However, in the conventional outer wall material, a plurality of convex veins in the longitudinal direction are arranged adjacent to each other on the surface of the fiberboard, and a thin wood plate is pasted on the surface along the convex veins. Because it is attached, two kinds of materials, fiberboard and wood thin veneer, are required, and these are attached with an adhesive, which raises the cost of the material and takes time to manufacture. there were.

前記押出成形によって、円筒の外周部の半分より小さい部位を構成する湾曲板部２が前記押出成形の押出し方向と直交する方向に複数連設するように形成され、
前記湾曲板部２の内側には、背面壁部５が前記湾曲板部２の両端部間に形成され、
前記背面壁部５が前記湾曲板部２と同様に湾曲していることを特徴とする。
請求項３に記載の発明は、請求項２に記載の外壁において、
前記背面壁部５と前記湾曲板部２との間には、この湾曲板部２の周方向中央部から前記背面壁部５に向けて延びる仕切壁６が押出し方向に沿って形成されていることを特徴とする。 In order to solve the above-mentioned problem, the invention according to claim 1 is an outer wall material 1 obtained by mixing and extruding a cellulose-based fine particle and a resin, for example, as shown in FIGS.
By the extrusion molding, the curved plate portion 2 constituting a portion smaller than half of the outer peripheral portion of the cylinder is formed so as to be continuously provided in a direction orthogonal to the extrusion direction of the extrusion molding,
Inside the curved plate portion 2, a back wall portion 5 is formed between both end portions of the curved plate portion 2,
Between the back wall 5 and the curved plate 2, a partition wall 6 extending from the circumferential center of the curved plate 2 toward the back wall 5 is formed along the pushing direction. It is characterized by that.
The invention according to claim 2 is an outer wall material 1 obtained by mixing and extruding a cellulose-based fine particle and a resin, for example, as shown in FIG.
By the extrusion molding, the curved plate portion 2 constituting a portion smaller than half of the outer peripheral portion of the cylinder is formed so as to be continuously provided in a direction orthogonal to the extrusion direction of the extrusion molding,
Inside the curved plate portion 2, a back wall portion 5 is formed between both end portions of the curved plate portion 2,
The back wall portion 5 is curved similarly to the curved plate portion 2.
According to a third aspect of the present invention, in the outer wall according to the second aspect,
Between the back wall 5 and the curved plate 2, a partition wall 6 extending from the circumferential center of the curved plate 2 toward the back wall 5 is formed along the pushing direction. It is characterized by that.

ここで、前記セルロース系微粉粒とは、例えば、廃材等の木材の粗粉砕物、バカスの祖粉砕物、稲藁の粗粉砕物等における各種植物細胞体の原料材粗粉砕物を出発原料とし、これを磨砕処理することによって得ることができる。   Here, the cellulose-based fine particles are, for example, raw material raw material coarsely pulverized material of various plant cell bodies in wood coarsely pulverized material such as waste wood, Bacus ground pulverized material, and rice straw coarsely pulverized material. This can be obtained by grinding.

磨砕処理とは、粉砕処理と研磨処理とを併せ持つ処理を言うものであり、これら粉砕処理と研磨処理とを同時に行う処理であっても、粉砕処理を行った後、研磨処理を行う二工程からなる処理であってもよい。すなわち、ここで言う磨砕処理とは、後述するように、粗粉砕物から微粉砕物にする粉砕処理と、微粉際された粉粒を、繊維状態のものが絡み合い、その表面が繊毛で覆われている状態の粉粒形状から、表面に繊毛が少ない状態となるように表面研磨する研磨処理とを併せた処理を指している。   The grinding process refers to a process having both a grinding process and a polishing process. Even if the grinding process and the polishing process are performed at the same time, the grinding process is performed after the grinding process. The process which consists of may be sufficient. In other words, the grinding treatment referred to here is, as will be described later, a pulverization process from a coarsely pulverized product to a finely pulverized product, and finely pulverized powder particles entangled with each other in a fiber state, and the surface is covered with cilia. It refers to a process that combines a polishing process in which the surface is polished so that the surface has a small amount of cilia from the broken powder shape.

前記セルロース系微粉粒は、上記のように磨砕処理により粒径状に形成されることで、通常の木粉のような繊毛上の突出部分が少なくなり、水（湿気を含む）や溶剤などを吸着しにくくなっている。   The cellulose-based fine particles are formed into a particle size by grinding as described above, so that protruding portions on the cilia like normal wood flour are reduced, and water (including moisture), solvent, etc. It becomes difficult to adsorb.

また、前記樹脂とは、硬質樹脂や軟質樹脂のことであり、塩化ビニル樹脂、発泡塩化ビニル樹脂、ポリエチレン樹脂、ポリプロピレン樹脂、フェノール樹脂、ウレタン樹脂、ポリウレタン樹脂、ＡＢＳ樹脂、ポリスチレン樹脂等が用いられるが、中でも塩化ビニル樹脂、ポリエチレン樹脂、ポリプロピレン樹脂が、成形部材を形成するには好適である。また、樹脂は廃材の樹脂から得るようにしてもよい。   The resin is a hard resin or a soft resin, and vinyl chloride resin, foamed vinyl chloride resin, polyethylene resin, polypropylene resin, phenol resin, urethane resin, polyurethane resin, ABS resin, polystyrene resin, etc. are used. However, among them, vinyl chloride resin, polyethylene resin, and polypropylene resin are suitable for forming a molded member. The resin may be obtained from waste resin.

Similar to the outer wall material 1, the outer wall material 101 is obtained by mixing and extruding cellulose-based fine particles and a resin, and is formed with a curved plate portion 2 constituting a portion smaller than half of the outer peripheral portion of the cylinder. Yes. The curved plate portion 2 has the same shape as the curved plate portion 2 of the outer wall material 1, and a connecting portion 3 is formed at the lower end portion thereof. The connecting portion 3 has the same shape as the connecting portion 3 of the outer wall material 1. A back wall 5 is formed between both ends of the curved plate 2 inside the curved plate 2 of the outer wall material 101. Furthermore, a partition wall 6 is formed between the back wall portion 5 and the curved plate portion 2 along the extrusion direction, and two hollow portions are formed inside the outer wall material 1 by the partition wall 6.

In such an outer wall material 102, the curved plate portion 2 is curved outward, and the back wall portion 102 b is about half the thickness of the outer wall including the wall panel 10, the vertical trunk edge 9 a, and the base incombustible material 8. Since the hollow portion 27 is located at the position, the width in the lateral direction is larger than that of the hollow portion 7 of the outer wall material 1 or the outer wall material 101.
The hollow portion 7 of the outer wall material 1, 101 has a rear wall 5 located on the surface of the outer wall, and thus has a small lateral width and is insufficient for housing the shutter 28. Since the hollow portion 27 of 102 can increase the width in the lateral direction using the arc of the curved plate portion 2 and half of the outer wall thickness, the shutter 28 can be easily accommodated in the large hollow portion 27.
