間柱１０３は、外装材１０１と内装材１０２との間に配置された複数の柱（不図示）間に配置されている。つまり、複数の構造用パネル１も柱間に配置されている。構造用パネル１は、間柱１０３と柱との間に配置されているものもあり、この場合は間柱１０３と柱との両方に取り付けられている。なお、柱間に間柱１０３が設けられていない場合は、構造用パネル１は柱に取り付けられる。なお、間柱１０３は、本発明の「柱」に相当する。 The studs 103 are arranged between a plurality of pillars (not shown) arranged between the exterior material 101 and the interior material 102. That is, the plurality of structural panels 1 are also arranged between the columns. Some structural panels 1 are arranged between the studs 103, and in this case, they are attached to both the studs 103 and the pillars. If the studs 103 are not provided between the pillars, the structural panel 1 is attached to the pillars. The stud 103 corresponds to the “pillar” of the present invention.

構造用パネル１は、図１〜図３に示すように、コア材１０と、表面材１１と、裏面材１２とを有する。コア材１０は、アルミニウム又はアルミニウム合金などの軽金属から構成され、所定の厚みを有し、当該厚み方向Ａに貫通する筒状孔１０ａが多数形成された矩形の板状部材である。コア材１０は、図２に示すように、幅方向Ｂ（後述の一端面１０ｂの面内方向と平行な方向であって厚み方向Ａと直交する一方向）に関して、隣接する２つの間柱１０３間の長さよりも若干短い長さを有し、間柱１０３間に配置可能に構成されている。また、コア材１０は、軽金属以外の紙、樹脂（繊維強化プラスチック含む）、不織布などの材料から構成されていてもよく、特に限定するものではない。各筒状孔１０ａは、図３（ａ）に示すように、断面六角形に形成された、所謂ハニカムコアとして形成されている。つまり、コア材１０は、公知のハニカムコア材が採用されている。なお、筒状孔１０ａの断面形状は、正六角形以外の形状でもよく、例えば、円形、四角形などでもよく、特に限定するものではない。 As shown in FIGS. 1 to 3, the structural panel 1 has a core material 10, a front surface material 11, and a back surface material 12. The core material 10 is a rectangular plate-shaped member that is made of a light metal such as aluminum or an aluminum alloy, has a predetermined thickness, and has a large number of cylindrical holes 10a penetrating in the thickness direction A. As shown in FIG. 2, the core material 10 is provided between two adjacent studs 103 in the width direction B (one direction parallel to the in-plane direction of the one end face 10b described later and orthogonal to the thickness direction A). Has a length slightly shorter than the length of the stud 103, and is arranged between the studs 103. The core material 10 may be made of a material other than light metal, such as paper, resin (including fiber reinforced plastic), and non-woven fabric, and is not particularly limited. As shown in FIG. 3A, each cylindrical hole 10a is formed as a so-called honeycomb core having a hexagonal cross section. That is, as the core material 10, a known honeycomb core material is adopted. The cross-sectional shape of the cylindrical hole 10a may be a shape other than a regular hexagon, and may be, for example, a circle or a quadrangle, and is not particularly limited.

表面材１１は、本実施形態において、所定の引張強度を有し、その厚みが０．５ｍｍ以上２．０ｍｍ以下の公知の透湿シートが採用されている。また、表面材１１は、図２及び図３（ｂ）に示すように、コア材１０の厚み方向Ａの一端面１０ｂに接着剤を介して設けられており、内装材１０２と対向する。表面材１１は、本体部１１ａと、一対の延在部１１ｂとを有する。本体部１１ａは、コア材１０の一端面１０ｂとほぼ同じ平面サイズを有しており、一端面１０ｂ全体と対向しつつ接着されている。一対の延在部１１ｂは、本体部１１ａの幅方向Ｂの両端から外側に延在して形成されている。つまり、一対の延在部１１ｂは、コア材１０の一端面１０ｂの幅方向Ｂの両端縁よりも外側にそれぞれ延在している。また、一対の延在部１１ｂは、図３（ａ）に示すように、上下方向Ｃに長尺に延在し、本体部１１ａの幅方向Ｂの両端の全長に亘って形成されている。また、延在部１１ｂは、図２に示すように、コア材１０が間柱１０３間に配置されたときに、間柱１０３と厚み方向Ａに対向可能に形成されている。なお、延在部１１ｂの幅方向Ｂの長さは、コア材１０が間柱１０３間に配置された状態において、間柱１０３の幅方向Ｂの長さの半分以下に形成されていることが好ましい。本実施形態における延在部１１ｂの幅方向Ｂの長さは、３０ｍｍ以上６０ｍｍ以下の範囲で形成されている。 In the present embodiment, the surface material 11 is a known moisture-permeable sheet having a predetermined tensile strength and a thickness of 0.5 mm or more and 2.0 mm or less. Further, as shown in FIGS. 2 and 3B, the surface material 11 is provided on the one end surface 10b of the core material 10 in the thickness direction A via an adhesive and faces the interior material 102. The surface material 11 has a main body portion 11a and a pair of extending portions 11b. The main body portion 11a has substantially the same plane size as the one end surface 10b of the core material 10, and is bonded while facing the entire one end surface 10b. The pair of extending portions 11b are formed to extend outward from both ends in the width direction B of the main body portion 11a. That is, the pair of extending portions 11b respectively extend outside the both end edges of the one end face 10b of the core material 10 in the width direction B. In addition, as shown in FIG. 3A, the pair of extending portions 11b extend in the vertical direction C and are formed over the entire length of both ends in the width direction B of the main body portion 11a. Further, as shown in FIG. 2, the extending portion 11b is formed so as to face the stud 103 in the thickness direction A when the core material 10 is arranged between the studs 103. The length of the extending portion 11b in the width direction B is preferably half or less of the length of the stud 103 in the width direction B when the core material 10 is arranged between the studs 103. The length of the extending portion 11b in the width direction B in the present embodiment is in the range of 30 mm or more and 60 mm or less.

表面材１１には、厚み方向Ａに貫通する複数の孔１３が形成されている。これら複数の孔１３は、１つの筒状孔１０ａに対して１つ以上が連通可能なように、表面材１１に形成されている。また、孔１３の孔径は、湿気を通過させることが可能な大きさを有しておればよい。本実施形態においては、表面材１１として、公知の透湿シートを採用しているが、透湿防水シート、通気シート、防湿シート、防水シートなどの公知のシートを採用してもよい。さらに、表面材１１の材料としては、例えば、不織布、樹脂、木、及び、これらの複合材料のいずれかから構成されたフィルム状、シート状及びボード状のいずれかを採用することが可能である。 A plurality of holes 13 penetrating in the thickness direction A are formed in the surface material 11. The plurality of holes 13 are formed in the surface material 11 so that one or more can communicate with one cylindrical hole 10a. Further, the hole diameter of the hole 13 may be a size that allows moisture to pass through. In the present embodiment, a known moisture-permeable sheet is used as the surface material 11, but a known sheet such as a moisture-permeable waterproof sheet, a ventilation sheet, a moisture-proof sheet, or a waterproof sheet may be employed. Further, as the material of the surface material 11, for example, any of a film shape, a sheet shape, and a board shape made of any of a non-woven fabric, a resin, wood, and a composite material thereof can be adopted. ..

裏面材１２は、本実施形態において、所定の引張強度を有し、その厚みが０．５ｍｍ以上２．０ｍｍ以下の公知の透湿防水シートが採用されている。また、裏面材１２は、図２及び図３（ｂ）に示すように、コア材１０の厚み方向Ａの他端面１０ｃに接着剤を介して設けられており、外装材１０１と対向する。つまり、裏面材１２は、厚み方向Ａにおいて、外装材１０１と表面材１１との間に配置されている。裏面材１２は、表面材１１の本体部１１ａと同じ形状及びサイズを有している。裏面材１２は、コア材１０の他端面１０ｃとほぼ同じ平面サイズを有しており、他端面１０ｃ全体と対向しつつ接着されている。 In the present embodiment, as the back material 12, a known moisture-permeable waterproof sheet having a predetermined tensile strength and a thickness of 0.5 mm or more and 2.0 mm or less is adopted. As shown in FIGS. 2 and 3B, the back surface material 12 is provided on the other end surface 10c of the core material 10 in the thickness direction A via an adhesive and faces the exterior material 101. That is, the back surface material 12 is arranged between the exterior material 101 and the surface material 11 in the thickness direction A. The back surface material 12 has the same shape and size as the main body portion 11 a of the front surface material 11. The back surface material 12 has substantially the same plane size as the other end surface 10c of the core material 10, and is bonded while facing the entire other end surface 10c.

裏面材１２には、図３（ｂ）に示すように、厚み方向Ａに貫通する複数の孔１４が形成されている。これら複数の孔１４は、孔１３と同様に、１つの筒状孔１０ａに対して１つ以上が連通可能なように、裏面材１２に形成されている。本実施形態における孔１４の孔径は、０．５μｍ以上３μｍ以下の範囲で形成されている。これにより、雨（大きさが約２０００μｍ）、霧雨（大きさが約１００μｍ）が通過するのを防ぐことができ、水蒸気粒子（０．０００４μｍ）を通過させることができる。すなわち、裏面材１２が透湿性及び防水性を有することとなる。また、本実施形態においては、裏面材１２として、公知の透湿防水シートを採用しているが、透湿シート、通気シート、防湿シート、防水シートなどの公知のシートを採用してもよい。さらに、裏面材１２の材料としては、例えば、不織布、樹脂、木、及び、これらの複合材料のいずれかから構成されたフィルム状、シート状及びボード状のいずれかを採用することが可能である。 As shown in FIG. 3B, the back surface material 12 is formed with a plurality of holes 14 penetrating in the thickness direction A. Similar to the holes 13, the plurality of holes 14 are formed in the back surface material 12 so that one or more holes can communicate with one cylindrical hole 10a. The hole diameter of the hole 14 in the present embodiment is in the range of 0.5 μm or more and 3 μm or less. This makes it possible to prevent rain (size of about 2000 μm) and drizzle (size of about 100 μm) from passing therethrough, and allow water vapor particles (0.0004 μm) to pass therethrough. That is, the back material 12 has moisture permeability and waterproofness. Further, in the present embodiment, a known moisture-permeable waterproof sheet is used as the back material 12, but a known sheet such as a moisture-permeable sheet, a ventilation sheet, a moisture-proof sheet, or a waterproof sheet may be employed. Furthermore, as the material of the backing material 12, for example, any of a film shape, a sheet shape, and a board shape made of any of a non-woven fabric, a resin, wood, and a composite material thereof can be adopted. ..

要するに、表面材１１が透湿防水性を有し、裏面材１２が透湿性のみを有していてもよいし、表面材１１及び裏面材１２の両方が透湿性のみを有していてもよい。また、表面材１１及び裏面材１２の両方が、透湿防水性を有していてもよい。 In short, the surface material 11 may have moisture permeability and waterproofness, and the back surface material 12 may have only moisture permeability, or both the surface material 11 and the back surface material 12 may have moisture permeability only. .. Further, both the surface material 11 and the back surface material 12 may have moisture permeability and waterproof property.

このような構造用パネル１は、図２に示すように、間柱１０３間にコア材１０及び裏面材１２を配置させ、表面材１１の延在部１１ｂを厚み方向Ａに間柱１０３と対向させた状態で、延在部１１ｂが上下方向Ｃの全長に亘って複数の釘１０６で間柱１０３に固定される。こうして、構造用パネル１の取付構造が構成される。本実施形態においては、延在部１１ｂが釘１０６によって間柱１０３に固定されているが、釘１０６に代えてネジで延在部１１ｂを間柱１０３に固定してもよい。 In such a structural panel 1, as shown in FIG. 2, the core material 10 and the back surface material 12 are arranged between the studs 103, and the extending portions 11b of the surface material 11 are opposed to the studs 103 in the thickness direction A. In this state, the extending portion 11b is fixed to the stud 103 by the plurality of nails 106 over the entire length in the vertical direction C. Thus, the mounting structure of the structural panel 1 is constructed. In the present embodiment, the extending portion 11b is fixed to the stud 103 by the nail 106, but the extending portion 11b may be fixed to the stud 103 by screws instead of the nail 106.

胴縁１０４は、図１及び図２に示すように、厚み方向Ａに関して間柱１０３と外装材１０１との間に配置され、間柱１０３に固定されている。これにより、構造用パネル１と外装材１０１との間であって隣接する胴縁１０４間のそれぞれに、通気部１０５が構成されている。これら通気部１０５が図示しない領域で木造住宅の外部と連通している。このため、内装材１０２側からの湿気を、構造用パネル１を通過させて通気部１０５を介して外部に排出することができる。また、裏面材１２が防水性を有しているため、通気部１０５を介して外部から霧雨などが侵入してきたとしても、構造用パネル１内に侵入するのを防止することができる。 As shown in FIGS. 1 and 2, the furring strip 104 is arranged between the stud 103 and the exterior material 101 in the thickness direction A, and is fixed to the stud 103. Thereby, the ventilation part 105 is comprised between the structural panel 1 and the exterior material 101, and between each adjacent furring strips 104. These ventilation parts 105 communicate with the outside of the wooden house in a region (not shown). Therefore, moisture from the interior material 102 side can be passed through the structural panel 1 and discharged to the outside via the ventilation portion 105. Further, since the back material 12 is waterproof, even if drizzle or the like enters from the outside through the ventilation part 105, it can be prevented from entering the structural panel 1.

以上に述べたように、本実施形態の外壁構造１００は、表面材１１が延在部１１ｂを有していることで、構造用パネル１が間柱１０３間に当該延在部１１ｂを介して容易に取り付けられた、木造住宅の外壁構造となる。また、構造用パネル１の取付構造においても、表面材１１が延在部１１ｂを有していることで、構造用パネル１が間柱１０３間に当該延在部１１ｂを介して容易に取り付けられた、構造用パネル１の取付構造となる。 As described above, in the outer wall structure 100 of the present embodiment, since the surface material 11 has the extending portions 11b, the structural panel 1 can easily be interposed between the studs 103 via the extending portions 11b. It becomes the outer wall structure of the wooden house attached to. Further, also in the mounting structure of the structural panel 1, since the surface material 11 has the extending portion 11b, the structural panel 1 is easily attached between the studs 103 via the extending portion 11b. The mounting structure of the structural panel 1 is obtained.

構造用パネル１の表面材１１が延在部１１ｂを有していることで、当該延在部１１ｂを介して構造用パネル１を間柱１０３間に取り付けて固定することが可能となる。このため、構造用パネル１を間柱１０３間に容易に取り付けることが可能となる。この結果、施工がし易くなる。また、表面材１１及び裏面材１２が、透湿性を有しているため、構造用パネル１が内装材１０２側からの湿気を通すことが可能となる。このため、住宅内の湿気を外部に排出することができる。また、裏面材１２が、透湿防水シートから構成されているため、霧雨などを通さず、湿気のみを通すことが可能となる。 Since the surface material 11 of the structural panel 1 has the extending portion 11b, the structural panel 1 can be attached and fixed between the studs 103 via the extending portion 11b. Therefore, the structural panel 1 can be easily attached between the studs 103. As a result, construction becomes easy. Further, since the front surface material 11 and the back surface material 12 have moisture permeability, the structural panel 1 can pass moisture from the interior material 102 side. Therefore, the moisture in the house can be discharged to the outside. Further, since the back material 12 is made of a moisture-permeable waterproof sheet, it is possible to allow only moisture to pass without passing drizzle or the like.

以上、本発明の好適な実施の形態について説明したが、本発明は上述の実施の形態に限られるものではなく、特許請求の範囲に記載した限りにおいて様々な変更が可能なものである。上述の実施形態における構造用パネル１の延在部１１ｂは、本体部１１ａの幅方向Ｂの両端の全長に亘って形成されているが、部分的に形成されていてもよい。また、延在部１１ｂは、一端面１０ｂの面内方向に平行であって幅方向Ｂを除く一方向において、一端面１０ｂの両側縁よりも外側に本体部１１ａからそれぞれ延在して形成されておればよい。また、延在部１１ｂは、本体部１１ａの上下方向Ｃの両端から外側（上下方向Ｃ）に延在するように形成されていてもよい。この場合、延在部１１ｂを釘やネジで土台、胴差及び軒桁などの横架材に固定してもよい。また、表面材１１は、延在部１１ｂに加えて、本体部１１ａの上下方向Ｃの両端から上下方向Ｃに延在する延在部を有していてもよい。そして、当該延在部を釘やネジで土台、胴差及び軒桁などの横架材に固定してもよい。 Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made as long as they are set forth in the claims. The extending portion 11b of the structural panel 1 in the above-described embodiment is formed over the entire length of both ends of the body portion 11a in the width direction B, but may be formed partially. The extending portions 11b are formed to extend from the main body portion 11a to the outside of both side edges of the one end face 10b in one direction parallel to the in-plane direction of the one end face 10b and excluding the width direction B. I have to Further, the extending portions 11b may be formed so as to extend outward (vertical direction C) from both ends of the main body portion 11a in the vertical direction C. In this case, the extending portion 11b may be fixed to the base, the body difference, and the eaves girder or other horizontal member with nails or screws. In addition to the extending portion 11b, the surface material 11 may have extending portions extending in the vertical direction C from both ends of the main body portion 11a in the vertical direction C. Then, the extending portion may be fixed to a base, a body difference, and a lateral member such as eaves girders with nails or screws.

また、構造用パネル１の筒状孔１０ａ内に、発泡樹脂、グラスウールなどの断熱材を充填していてもよい。このとき、発泡ウレタンなどの発泡樹脂を筒状孔１０ａ内に充填する場合は、当該発泡樹脂で、表面材１１及び裏面材１２と、コア材１０とを接着することが可能となる。このため、発泡樹脂以外で、コア材１０と、表面材１１及び裏面材１２とを接着するための接着剤が不要となる。 Further, the cylindrical hole 10a of the structural panel 1 may be filled with a heat insulating material such as foamed resin or glass wool. At this time, when the foamed resin such as urethane foam is filled in the cylindrical hole 10a, the front surface material 11 and the back surface material 12 and the core material 10 can be bonded with the foamed resin. Therefore, an adhesive other than the foamed resin for bonding the core material 10, the front surface material 11 and the back surface material 12 is not required.
