Description

本発明は、窯業系サイディング（外壁材）にて外壁を構成するための技術に関するものであり、より詳しくは、出隅部における窯業系サイディング（外壁材）の納まりに関する。   The present invention relates to a technique for configuring an outer wall with a ceramic siding (outer wall material), and more particularly, to a storage of a ceramic siding (outer wall material) at a protruding corner.

従来、例えば特許文献１に開示されるように、窯業系サイディングにて構成される平板状の外壁材を用いて外壁を構成する技術が知られている。この外壁材は、固定金具により柱などの躯体側に留め付けられ、縦方向、横方向に並べて配置されて一連の外壁面を構成する。   Conventionally, as disclosed in, for example, Patent Document 1, a technique for forming an outer wall using a flat outer wall material formed by ceramic siding is known. This outer wall material is fastened to a housing side such as a pillar by a fixing bracket, and is arranged side by side in the vertical direction and the horizontal direction to constitute a series of outer wall surfaces.

そして、特許文献１では、平面視略Ｌ字型のコーナー用外壁材を用いることなく、平板状の外壁材を付け合せてコーナー部（出隅部）を形成することについて記載されている。具体的には、出隅部で付け合せられる一対の外壁材について、各外壁材の端部に平面視約４５度方向のコーナー傾斜面を形成し、当該コーナー傾斜面同士を対向させることで、外壁材同士が直角となるように配置して出隅部を構成するものである。   And in patent document 1, it describes about forming a corner part (protruding corner part) by putting together a flat-shaped outer wall material, without using the outer wall material for corners of a planar view substantially L-shape. Specifically, with respect to a pair of outer wall materials to be attached at the projecting corners, a corner inclined surface in a direction of about 45 degrees in plan view is formed at the end of each outer wall material, and the corner inclined surfaces are opposed to each other, The protruding corners are configured by arranging the materials at right angles.

特開２０１１−３８３３３号公報JP 2011-38333 A

以上のような外壁材を用いた場合において、地震が発生した際には、外壁材が面内方向にずれることが懸念され、出隅部においては、互いに直交する関係にある一方の外壁材の端部が、他方の外壁材の端部に押し付けられる状況が生じ得る。   In the case of using the outer wall material as described above, when an earthquake occurs, there is a concern that the outer wall material may shift in the in-plane direction. A situation may occur where the end is pressed against the end of the other outer wall material.

この場合、特許文献１のような構成であると、コーナー傾斜面の部位は肉厚の薄い薄肉部で構成されるため、直交する外壁材が地震で揺れた際に、揺れの方向によっては直交する外壁材に対して交差する方向へずれるため、薄肉部同士で押し合いが発生し、薄肉部の破損が発生しやすいことが懸念される。   In this case, in the case of the configuration as in Patent Document 1, the portion of the corner inclined surface is configured by a thin portion having a small thickness, and therefore when the orthogonal outer wall material is shaken by an earthquake, it is orthogonal depending on the direction of shaking. Since it shifts in a direction intersecting the outer wall material, the thin portions are pressed against each other, and there is a concern that the thin portions are likely to be damaged.

また、特許文献１では、平面視約４５度方向のコーナー傾斜面同士を対向させるとともに、隙間にシーリング材を充填する構成であるため、経年によりシーリング材の劣化が生じることになる。また、地震の際に外壁材がずれた際には、シーリング材の剥がれの発生等が懸念され、止水性が悪化することが懸念される。   Moreover, in patent document 1, since it is the structure which makes the corner inclined surfaces of a 45 degree direction planar view oppose, and is filled with the sealing material in a clearance gap, degradation of a sealing material arises by aging. Further, when the outer wall material is displaced during an earthquake, there is a concern that the sealing material may be peeled off, and the water stoppage may be deteriorated.

本発明は以上の問題に鑑み、外壁の出隅部について新規な構造を提案するものである。また、外壁の出隅部のみならず、外壁材を用いて袖壁や柱（門柱、ポーチ柱）などの外壁材構造物を構成する場合についても適用できる新規な構造を提案するものである。   In view of the above problems, the present invention proposes a novel structure for the outer corner of the outer wall. Further, the present invention proposes a novel structure that can be applied not only to the corner of the outer wall but also to the case where an outer wall material structure such as a sleeve wall or a column (a gate column or a porch column) is configured using an outer wall material.

本発明の解決しようとする課題は以上の如くであり、次にこの課題を解決するための手段を説明する。   The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described.

また、縦片部５１ｅにはパッキン材５１ｑが貼付されており、裏合決部１３の表面（裏面部１３ｅ）と縦片部５１ｅの間の隙間がパッキン材５１ｑによって塞がれる。このようにパッキン材５１ｑを縦片部５１ｅにも配置することにより、外部から縦溝部５１ｇ側への水の浸入を効果的に防止することができ、止水性を高めることができる。   Moreover, the packing material 51q is affixed on the vertical piece 51e, and the gap between the front surface (back surface portion 13e) of the back decision portion 13 and the vertical piece 51e is closed by the packing material 51q. By arranging the packing material 51q in the vertical piece portion 51e as described above, it is possible to effectively prevent water from entering the vertical groove portion 51g from the outside, and to improve the water-stopping property.

また、パッキン材５１ｑに追加して、或いは、パッキン材５１ｑに代えて、裏合決部１３の見込み面部１３ｄと、縦片部５１ｄの間にパッキン材が配置されることとしてもよい。さらに、止水性を求めない場合や、見込み面部１３ｄに予めコーティングするといったことがなされる場合には、パッキン材５１ｑが配置されない構成としてもよい。   Further, in addition to the packing material 51q or instead of the packing material 51q, a packing material may be disposed between the prospective surface portion 13d of the back mating portion 13 and the vertical piece portion 51d. Further, when the waterproofing is not required or when the prospective surface portion 13d is coated in advance, the packing material 51q may not be disposed.

また、外壁材２１側の部位において、出隅接合部材５０は、外壁材２１の裏面２１ａに対し間隔をあけて対向する固定片部５２ａを有する。固定片部５２ａは、断面Ｌ字状のスペーサー３２を介して構造用合板４、及び、縦枠２にビス５５などの固定具にて留め付けられる。   In addition, in the portion on the outer wall material 21 side, the protruding corner joining member 50 has a fixed piece portion 52 a that is opposed to the back surface 21 a of the outer wall material 21 with a space therebetween. The fixing piece 52a is fastened to the structural plywood 4 and the vertical frame 2 with a fixing tool such as a screw 55 via a spacer 32 having an L-shaped cross section.

固定片部５２ａにおいて、外壁材２１の側端部１２に近い側には、外壁材２１の裏面２１ａに向かって伸びる縦片部５２ｂが形成される。   In the fixed piece portion 52 a, a vertical piece portion 52 b extending toward the back surface 21 a of the outer wall material 21 is formed on the side close to the side end portion 12 of the outer wall material 21.

固定片部５２ａにおいて、外壁材２１の側端部１２から遠い側には、外壁材２１の裏面２１ａに向かって伸びる縦片部５２ｆが形成され、縦片部５２ｆの端部が裏面２１ａに当接する。縦片部５２ｆは裏面２１ａに当接した箇所で折り返される。   In the fixed piece portion 52a, a vertical piece portion 52f extending toward the back surface 21a of the outer wall material 21 is formed on the side far from the side end portion 12 of the outer wall material 21, and the end portion of the vertical piece portion 52f contacts the back surface 21a.

そして、固定片部５２ａと、縦片部５２ｂと、縦片部５２ｆによって、断面略コ字状の縦溝部５２ｇが形成される。この縦溝部５２ｇに外部から浸入した雨水などは、縦溝部５２ｇを通じて下方へと排出される。なお、縦片部５２ｆが水返し部として機能することで、縦片部５２ｆよりも奥への水の浸入が防がれるものであり、縦片部５２ｆについては、裏面２１ａに当接させない構成とすることも考えられる。   The fixed piece portion 52a, the vertical piece portion 52b, and the vertical piece portion 52f form a vertical groove portion 52g having a substantially U-shaped cross section. Rainwater or the like that has entered the vertical groove 52g from the outside is discharged downward through the vertical groove 52g. The vertical piece portion 52f functions as a water return portion to prevent water from entering deeper than the vertical piece portion 52f. The vertical piece portion 52f is configured not to contact the back surface 21a. It can also be considered.

また、縦片部５２ｂにおいて、固定片部５２ａと反対側の端部からは、外壁材２１の側端部２２に向かって伸び、外壁材２１の裏面２１ａに対向する縦片部５２ｃが形成される。縦片部５２ｃと外壁材２１の裏面２１ａの間の隙間には、後述する横ずれ防止金具６２（図６参照）の縦片部６２ｃ（図６参照）を納めることができる。縦片部５２ｃは、前述の縦片部５１ｃと重ねられるようにして設けられる。   Further, in the vertical piece portion 52b, a vertical piece portion 52c extending from the end portion on the opposite side to the fixed piece portion 52a toward the side end portion 22 of the outer wall material 21 and facing the back surface 21a of the outer wall material 21 is formed. The In the gap between the vertical piece portion 52c and the back surface 21a of the outer wall member 21, a vertical piece portion 62c (see FIG. 6) of a lateral shift prevention metal fitting 62 (see FIG. 6) described later can be stored. The vertical piece portion 52c is provided so as to overlap the above-described vertical piece portion 51c.

そして、縦片部５２ｃにはパッキン材５２ｐが貼付され、外壁材２１の裏面２１ａと縦片部５２ｃの間の隙間がパッキン材５２ｐによって塞がれる。このパッキン材５２ｐにより、外部から縦溝部５２ｇ側への水の浸入を効果的に防止することができ、止水性を高めることができる。   And the packing material 52p is affixed on the vertical piece part 52c, and the clearance gap between the back surface 21a of the outer wall material 21 and the vertical piece part 52c is block | closed by the packing material 52p. By this packing material 52p, it is possible to effectively prevent water from entering from the outside to the vertical groove portion 52g side, and it is possible to increase the water stoppage.

また、縦片部５２ｃにおいて、縦片部５２ｂと反対側の端部には、室外側に向かって伸びる縦片部５２ｄが形成される。縦片部５２ｄは、前述の縦片部５１ｅと隙間無く重ねられるようにして設けられる。   Further, in the vertical piece portion 52c, a vertical piece portion 52d extending toward the outdoor side is formed at an end portion opposite to the vertical piece portion 52b. The vertical piece 52d is provided so as to overlap the vertical piece 51e described above without any gap.

また、縦片部５２ｄ，５１ｅは、裏合決部２３の裏面部２３ｅに当着される構成とすることで、縦片部５２ｅ，５１ｅと裏面部１３ｅの間に隙間が形成しないようにすることができ、止水性を高めることができる。また、縦片部５１ｅによって、裏合決部２３の表面（見込み面部２３ｄ）を覆い隠すことができる。   Further, the vertical piece portions 52d and 51e are configured to be attached to the back surface portion 23e of the back-to-back determination portion 23 so that no gap is formed between the vertical piece portions 52e and 51e and the back surface portion 13e. Can be improved. In addition, the vertical piece portion 51e can cover the surface (the prospective surface portion 23d) of the back-to-back determination portion 23.

以上の出隅接合部材５０の室外側において外壁材１１，２１の側端部１２，２２が近接して配置され、側端部１２，２２の間に角部隙間５３が構成される。   The side end portions 12 and 22 of the outer wall materials 11 and 21 are disposed close to each other on the outdoor side of the above-described protruding corner joining member 50, and a corner gap 53 is formed between the side end portions 12 and 22.

そして、角部隙間５３に水が浸入した際には、パッキン材５１ｐ，５１ｑ，５２ｐによる止水性能が発揮されるとともに、仮に、パッキン材５１ｐ，５１ｑ，５２ｐを通過してしまった場合でも、縦溝部５１ｇ，５２ｇで捕捉して下方へ水を排出することができ、出隅接合部材５０を通過して外壁材１１，２１の裏面の奥まで水が浸入してしまうことを防止できる。   And when water permeates into the corner gap 53, the water stopping performance by the packing materials 51p, 51q, 52p is exhibited, and even if the packing materials 51p, 51q, 52p have been passed, It is possible to catch water by the vertical groove portions 51g and 52g and discharge the water downward, and to prevent water from entering into the back of the outer wall materials 11 and 21 through the protruding corner joining member 50.

図４（Ａ）は外壁材１１，２１の側端部１２，２２の構成について示すものであり、外壁材１１の側端部１２には、最も端に配置されて見込み方向の面を形成する側端面１２ｍと、側端面１２ｍの室外側端部から外壁面１１ｂに至る平面視において傾斜面を構成するコーナー面１２ｎ（面取り部）と、側端面１２ｍの室内側端部から外壁材１１の幅方向内側へ向かう裏面部１３ｅと、裏面部１３ｅの側端面１２ｍとは反対側の端部から外壁材１１の裏面１１ａに向かう見込み面部１３ｄと、が形成されている。裏面部１３ｅと見込み面部１３ｄは平面視においてＬ字状に切り欠かれて構成され、裏合決部１３が構成される。   FIG. 4A shows the configuration of the side end portions 12 and 22 of the outer wall materials 11 and 21, and the side end portion 12 of the outer wall material 11 is arranged at the end to form a prospective surface. 12m of side end surfaces, corner surface 12n (chamfering part) which comprises an inclined surface in planar view from the outdoor side edge part of the side end surface 12m to the outer wall surface 11b, and the width | variety of the outer wall material 11 from the indoor side edge part of the side end surface 12m A back surface portion 13e that faces inward in the direction and a prospective surface portion 13d that faces the back surface 11a of the outer wall material 11 from the end opposite to the side end surface 12m of the back surface portion 13e are formed. The back surface portion 13e and the prospective surface portion 13d are configured to be cut out in an L shape in a plan view, and the back decision unit 13 is configured.

また、裏面部１３ｅの幅寸法Ｗｅは、見込み面部１３ｄの幅寸法Ｗｄよりも小さく構成される。そして、以上の外壁材１１の側端部１２の構成は、外壁材２１の側端部２２についても同様であり、裏面部２３ｅ、見込み面部２３ｄについてもそれぞれ幅寸法Ｗｅ，Ｗｄを有するものとしている。   Further, the width dimension We of the back surface part 13e is configured to be smaller than the width dimension Wd of the prospective surface part 13d. And the structure of the side edge part 12 of the above outer wall material 11 is the same also about the side edge part 22 of the outer wall material 21, and the back surface part 23e and the prospective surface part 23d shall have width dimensions We and Wd, respectively. .

また、外壁材１１の見込み面部１３ｄは外壁材２１の裏面２１ａに対向するように配置される。換言すれば、外壁材１１の側端面１２ｍは外壁材２１の裏面部２３ｅに対向するように配置される、或いは、外壁材１１の裏面１１ａが外壁材２１の見込み面部２３ｄよりも室内側に配置される。   Further, the prospective surface portion 13 d of the outer wall material 11 is disposed so as to face the back surface 21 a of the outer wall material 21. In other words, the side end surface 12m of the outer wall material 11 is disposed so as to face the back surface portion 23e of the outer wall material 21, or the back surface 11a of the outer wall material 11 is disposed more indoors than the prospective surface portion 23d of the outer wall material 21. Is done.

そして、外壁材１１の側端部１２と外壁材２１の裏面部２３ｅの間には、所定の幅を有する角部隙間５３を確保するようにして外壁材１１，２１が施工される。   And the outer wall materials 11 and 21 are constructed between the side edge part 12 of the outer wall material 11, and the back surface part 23e of the outer wall material 21 so that the corner | angular part clearance gap 53 which has a predetermined | prescribed width | variety may be ensured.

以上の構成により、図４（Ｂ）に示すように、地震により外壁材１１が矢印Ｘ１方向にずれた際には、見込み面部１３ｄが外壁材２１の裏面２１ａに突き当たる。   With the above configuration, as shown in FIG. 4B, when the outer wall material 11 is displaced in the direction of the arrow X1 due to an earthquake, the prospective surface portion 13d hits the back surface 21a of the outer wall material 21.

この際、上述した幅寸法Ｗｅ，Ｗｄの関係により、外壁材１１の側端部１２と外壁材２１の裏面部２３ｅの間の角部隙間５３は確保されるため、側端面１２ｍに近い肉厚の薄い部位が外壁材２１に突き当たることがない。   At this time, the corner gap 53 between the side end portion 12 of the outer wall material 11 and the back surface portion 23e of the outer wall material 21 is ensured by the relationship between the width dimensions We and Wd described above, and thus the wall thickness close to the side end surface 12m. The thin part of the wall does not hit the outer wall material 21.

これにより、肉厚が薄く構成される側端部１２について、地震発生時での損傷発生を防ぐことができる。なお、図４（Ｂ）では図４（Ａ）に示す出隅接合部材５０を省略しており、実際には、見込み面部１３ｄと裏面２１ａの間には出隅接合部材５０の縦片部５１ｄ，５２ｃ（図４（Ａ））が挟まれることになり、このことによっても、角部隙間５３は確保されることになる。   Thereby, about the side edge part 12 comprised thinly, generation | occurrence | production of the damage at the time of an earthquake occurrence can be prevented. In FIG. 4B, the protruding corner joining member 50 shown in FIG. 4A is omitted, and actually, the vertical piece portion 51d of the protruding corner joining member 50 is provided between the prospective surface portion 13d and the back surface 21a. , 52c (FIG. 4A) is sandwiched, and this also secures the corner gap 53.

また、図４（Ｂ）において、仮に、地震により外壁材２１が矢印Ｘ２方向にずれた場合でも、見込み面部２３ｄと裏面部１３ｅの間に十分な幅の隙間Ｓｘが形成されるため、見込み面部２３ｄが裏面部１３ｅに突き当たり、外壁材１１の側端部１２が損傷してしまうことを防止できる。なお、外壁材２１の矢印Ｘ２方向へのずれについては、後述する横ずれ防止金具６２（図６及び図７参照）によって防止される。   Further, in FIG. 4B, even if the outer wall material 21 is displaced in the arrow X2 direction due to an earthquake, a gap Sx having a sufficient width is formed between the prospective surface portion 23d and the rear surface portion 13e. It can prevent that 23d bumps into the back surface part 13e, and the side edge part 12 of the outer wall material 11 will be damaged. In addition, the shift | offset | difference to the arrow X2 direction of the outer wall material 21 is prevented by the lateral slip | shift prevention metal fitting 62 (refer FIG.6 and FIG.7) mentioned later.

また、図４（Ａ）に示すように、角部隙間５３が目立たないように、角部隙間５３の内側に位置する出隅接合部材５０の縦片部５１ｅの部位は、外壁材１１の外壁面１１ｂと同一色、或いは、同系色としつつ、縦片部５１ｅの先端部５１ｓが裏合決部２３の裏面部２３ｅに当接する、或いは、近接することとすることが好ましい。   Further, as shown in FIG. 4A, the portion of the vertical piece 51e of the protruding corner joining member 50 located inside the corner gap 53 is located outside the outer wall material 11 so that the corner gap 53 is not conspicuous. It is preferable that the front end portion 51s of the vertical piece portion 51e is in contact with or close to the back surface portion 23e of the back-to-back determination portion 23 while being the same color as or similar to the wall surface 11b.

これにより、敢えて角部隙間５３を確保して外壁材１１の側端部１２の損傷発生を防止する構成において、角部隙間５３を目立ち難くすることができ、出隅部１において外観上途切れのない連続性のある一連の外壁面を構成することができる。   Thereby, in the structure which dares to secure the corner gap 53 and prevents the occurrence of damage to the side end portion 12 of the outer wall material 11, the corner gap 53 can be made inconspicuous, and the appearance corner 1 can be cut off in appearance. A series of outer wall surfaces with no continuity can be constructed.

加えて、縦片部５１ｅの先端部５１ｓが裏合決部２３の裏面部２３ｅに当接することで、先端部５１ｓと裏面部２３ｅの間の隙間を生めることができ、当該隙間を通じて水が室内側に浸入してしまうことを防止でき、角部隙間５３を確保しつつも、止水性を高めることが可能となる。   In addition, the front end portion 51s of the vertical piece 51e abuts on the back surface portion 23e of the back-to-back determination portion 23, so that a gap between the front end portion 51s and the back surface portion 23e can be formed, and water is stored through the clearance. It is possible to prevent intrusion into the inner side, and it is possible to increase the water stop while securing the corner gap 53.

さらに、図４（Ａ）に示すように、外壁材１１,２１の側端部１２,２２において、一定の幅を有するコーナー面１２ｎ,２２ｎ（面取り部）を形成することで、当該コーナー面１２ｎ,２２ｎについて、外壁面１１ｂ,２１ｂと同一の塗装を施すことが可能となる。なお、コーナー面１２ｎ,２２ｎの幅Ｗｎは、側端面１２ｍ,２２ｍの幅Ｗｍよりも広く構成する（例えば、２倍以上とする）ことで、コーナー面１２ｎ,２２ｎについて外壁面１１ｂ,２１ｂと同一の塗装が施しやすいものとなる。   Furthermore, as shown in FIG. 4 (A), corner surfaces 12n and 22n (chamfered portions) having a certain width are formed at the side end portions 12 and 22 of the outer wall materials 11 and 21, whereby the corner surface 12n. , 22n can be applied with the same coating as the outer wall surfaces 11b, 21b. Note that the corner surfaces 12n and 22n have the same width Wn as the outer wall surfaces 11b and 21b by configuring the corner surfaces 12n and 22n to be wider than the width Wm of the side end surfaces 12m and 22m (for example, twice or more). It will be easy to apply.

以上のようにして、外壁面１１ｂ,２１ｂ、及び、コーナー面１２ｎ,２２ｎにおいて一連の連続した塗装による外観が構成され、角部隙間５３を目立ち難くすることができ、出隅部１において外観上途切れのない連続性のある一連の外壁面を構成することができる。   As described above, the outer wall surfaces 11b and 21b and the corner surfaces 12n and 22n have an appearance of a series of continuous coatings, and the corner gap 53 can be made inconspicuous. A series of continuous outer wall surfaces can be formed without interruption.

なお、図４（Ａ）において、側端面１２ｍ,２２ｍについては、コーナー面１２ｎ,２２ｎと同様に外壁面１１ｂ,２１ｂと同一の塗装を施すこととしてもよく、或いは、外壁面１１ｂ,２１ｂとは異なる単一の塗装を施すこととしてもよい。   In FIG. 4A, the side end faces 12m and 22m may be coated in the same manner as the outer wall surfaces 11b and 21b similarly to the corner surfaces 12n and 22n, or the outer wall surfaces 11b and 21b Different single coatings may be applied.

横ずれ防止金具６２は、躯体の一部を構成する構造用合板４にスペーサー３２を介して固定され、外壁材２１の裏面２１ａに対向する固定片部６２ａを有している。固定片部６２ａには、その厚み方向に貫通する貫通孔６２ｋが複数個所に設けられており、この貫通孔６２ｋにビスや釘などの固定具６３が差し込まれ、構造用合板４や縦枠２（スタッド）に対して横ずれ防止金具６２が留め付けられる。   The lateral slip prevention metal fitting 62 is fixed to the structural plywood 4 constituting a part of the housing via the spacer 32 and has a fixing piece portion 62a facing the back surface 21a of the outer wall material 21. The fixing piece portion 62a is provided with a plurality of through holes 62k penetrating in the thickness direction, and fixing tools 63 such as screws and nails are inserted into the through holes 62k, and the structural plywood 4 and the vertical frame 2 are inserted. The lateral slip prevention fitting 62 is fastened to the (stud).

固定片部６２ａにおいて、外壁材２１の側端部２２側の端部には、外壁材２１の裏面２１ａに向かって伸びる縦片部６２ｂが形成され、縦片部６２ｂの端部が裏面２１ａに当接する。   In the fixed piece portion 62a, a vertical piece portion 62b extending toward the back surface 21a of the outer wall material 21 is formed at an end portion on the side end portion 22 side of the outer wall material 21, and an end portion of the vertical piece portion 62b is formed on the back surface 21a. Abut.

また、縦片部６２ｂにおいて、固定片部６２ａと反対側の端部からは、外壁材２１の側端部２２に向かって伸び、外壁材２１の裏面２１ａに対向する縦片部６２ｃが形成される。   Further, in the vertical piece portion 62b, a vertical piece portion 62c extending from the end portion on the opposite side to the fixed piece portion 62a toward the side end portion 22 of the outer wall material 21 and facing the back surface 21a of the outer wall material 21 is formed. The

そして、縦片部６２ｃにおいて、縦片部６２ｂと反対側の端部には、室外側に向かって伸びる係合片部６２ｄが形成される。この係合片部６２ｄは、外壁材２１の側端部２２に形成される裏合決部２３の見込み面部２３ｄ（奥行き方向の面）に対向し、見込み面部２３ｄに当接することで、外壁材２１の矢印Ｘ２軸方向の横ずれを防止する機能を果たす。   In the vertical piece portion 62c, an engagement piece portion 62d extending toward the outdoor side is formed at the end opposite to the vertical piece portion 62b. The engaging piece 62d faces the prospective surface portion 23d (surface in the depth direction) of the back-to-back determination portion 23 formed on the side end portion 22 of the outer wall material 21, and comes into contact with the prospective surface portion 23d. 21 functions to prevent lateral displacement in the direction of the arrow X2 axis.

仮に、係合片部６２ｄが存在しない場合には、地震の際に縦枠２が傾いて外壁材２１が縦枠２からずれたとして、地震の揺れがおさまって縦枠２が直立に復帰したとしても、縦枠２と外壁材２１のずれが残ったままとなってしまう。係合片部６２ｄが存在することで縦枠２の復帰とともに外壁材２１も元の状態に戻すことができるものとなる。   If the engagement piece 62d does not exist, the vertical frame 2 is inclined and the outer wall member 21 is displaced from the vertical frame 2 in the event of an earthquake. However, the gap between the vertical frame 2 and the outer wall material 21 remains. The presence of the engaging piece portion 62d enables the outer wall material 21 to return to the original state as the vertical frame 2 is restored.

また、固定片部６２ａにおいて、外壁材２１の側端部２２から遠い側には、外壁材２１の裏面２１ａに向かって伸びる縦片部６２ｆが形成される。   Further, in the fixed piece portion 62a, a vertical piece portion 62f extending toward the back surface 21a of the outer wall member 21 is formed on the side far from the side end portion 22 of the outer wall member 21.

また、横ずれ防止金具６２の固定片部６２ａ、縦片部６２ｂ，６２ｆ、及び、縦片部６２ｃの一部は、出隅接合部材５０の縦溝部５２ｇの内側に納められる。これにより、図１に示すように、共に外壁材２１の上縁部に配置される固定金具４１と横ずれ防止金具６２を横方向に並べて配置することができる。   Further, the fixed piece portion 62 a, the vertical piece portions 62 b and 62 f, and a part of the vertical piece portion 62 c of the lateral shift prevention metal fitting 62 are accommodated inside the vertical groove portion 52 g of the protruding corner joining member 50. Thereby, as shown in FIG. 1, the fixing metal fitting 41 and the lateral displacement prevention metal fitting 62 which are both arranged at the upper edge portion of the outer wall material 21 can be arranged side by side in the horizontal direction.

以上のようにして本発明を実施することができる。
即ち、図４（Ａ）（Ｂ）に示すように、外壁材１１,２１の側端部１２,２１同士を接合してなる外壁の出隅部１の構造であって、各外壁材１１,２１の側端部１２,２１には、それぞれ裏合決部１３,２３が形成され、裏合決部１３,２３は、平面視において外壁材の厚み方向の縦面を構成する見込み面部１３ｄ,２３ｄと、平面視において見込み面部１３ｄ,２３ｄと直交する縦面を構成する裏面部１３ｅ,２３ｅと、を有し、裏面部１３ｅ,２３ｅの幅寸法Ｗｅは、見込み面部１３ｄ,２３ｄの幅寸法Ｗｄよりも小さく構成され、一方の外壁材１１の側端部１２の側端面１２ｍは、他方の外壁材２１の裏面部２３ｅに対向するように配置され、側端面１２ｍと他方の外壁材２１の裏面部２３ｅの間には、角部隙間５３が形成される、外壁の出隅部の構造とする。 The present invention can be implemented as described above.
That is, as shown in FIGS. 4 (A) and 4 (B), it is a structure of the outer corner 1 of the outer wall formed by joining the side end portions 12, 21 of the outer wall materials 11, 21, and each outer wall material 11, The side end portions 12 and 21 are respectively formed with back-side determination portions 13 and 23, and the back-side determination portions 13 and 23 are prospective surface portions 13d that constitute a vertical surface in the thickness direction of the outer wall member in plan view. 23d and back surface portions 13e and 23e constituting vertical surfaces orthogonal to the prospective surface portions 13d and 23d in plan view, and the width dimension We of the back surface portions 13e and 23e is the width dimension Wd of the prospective surface portions 13d and 23d. The side end surface 12m of the side end portion 12 of one outer wall member 11 is disposed so as to face the back surface portion 23e of the other outer wall member 21, and the side end surface 12m and the back surface of the other outer wall member 21 are arranged. A corner gap 53 is formed between the portions 23e, and the structure of the protruding corner portion of the outer wall is formed. To.

これにより、地震発生時には、一方の外壁材１１の見込み面部１３ｄが他方の外壁材２１の裏面２１ａに突き当たるため、一方の外壁材１１の側端部１２の側端面１２ｍが外壁材２１に突き当たることがなく、肉厚が薄い側端部１２について損傷の発生を防止できる。   Accordingly, when an earthquake occurs, the prospective surface portion 13d of one outer wall member 11 abuts against the back surface 21a of the other outer wall member 21, so that the side end surface 12m of the side end portion 12 of one outer wall member 11 abuts against the outer wall member 21. The occurrence of damage to the side end portion 12 having a small thickness can be prevented.

また、図２に示すように、一方の外壁材１１の裏合決部１３と、他方の外壁材２１の裏合決部２３の間には、両外壁材１１,２１の室内側に配置される出隅接合部材５０の縦片部５１ｅが配設され、縦片部５１ｅと、一方の外壁材１１の裏合決部１３の裏面部１３ｅの間には、パッキン材５１ｑが配設されることとする。また、パッキン材５１ｑに加え、又は、パッキン材５１ｑに代えて、縦片部５１ｄと、一方の外壁材１１の裏合決部１３の見込み面部１３ｄの間に、別のパッキン材を配設することとしてもよい。   Further, as shown in FIG. 2, the outer wall material 11 is disposed between the back wall determination portion 13 of one outer wall material 11 and the back wall determination portion 23 of the other outer wall material 21 on the indoor side of both the outer wall materials 11, 21. A vertical piece portion 51e of the protruding corner joining member 50 is disposed, and a packing material 51q is disposed between the vertical piece portion 51e and the back surface portion 13e of the back mating portion 13 of one outer wall member 11. I will do it. Further, in addition to the packing material 51q or in place of the packing material 51q, another packing material is disposed between the vertical piece portion 51d and the prospective surface portion 13d of the back-side determination portion 13 of the one outer wall material 11. It is good as well.

これにより、角部隙間５３に浸入した水をパッキン材５１ｑにて止水することができる。   Thereby, the water that has entered the corner gap 53 can be stopped by the packing material 51q.

また、図４（Ａ）に示すように、
出隅接合部材５０の縦片部５１ｅは、外壁材２１の裏合決部２３の裏面部２３ｅに当接する、又は、近接して配置される、こととする。なお、縦片部５１ｅは、外壁材１１の外壁面１１ｂと同一色、或いは、同系色とすることが好ましい。 Moreover, as shown in FIG.
The vertical piece 51e of the projecting corner joining member 50 is assumed to be in contact with or close to the back surface 23e of the back decision part 23 of the outer wall material 21. The vertical piece 51e is preferably the same color as the outer wall surface 11b of the outer wall material 11 or a similar color.

これにより、敢えて角部隙間５３を確保する構成において、他方の外壁材２１の見込み面部２３ｄを縦片部５１ｅで隠すことができ、角部隙間５３が目立ち難くなり、出隅部１において外観上途切れのない連続性のある一連の外壁面を構成することができる。また、縦片部５１ｅが裏面部２３ｅに当接することによれば、縦片部５１ｅと裏面部２３ｅの間の隙間を生めることができ、当該隙間を通じて水が室内側に浸入してしまうことを防止でき、角部隙間５３を確保しつつも、止水性を高めることが可能となる。   Thereby, in the structure which dares to secure the corner gap 53, the prospective surface portion 23d of the other outer wall material 21 can be hidden by the vertical piece 51e, and the corner gap 53 becomes inconspicuous, and the appearance corner 1 A series of continuous outer wall surfaces can be formed without interruption. Moreover, according to the vertical piece part 51e contacting the back surface part 23e, the clearance gap between the vertical piece part 51e and the back surface part 23e can be produced, and water will permeate into the indoor side through the said clearance gap. It is possible to prevent this, and it is possible to increase the water stop while securing the corner gap 53.

また、図２、図４（Ａ）に示すように、パッキン材５１ｑは、角部隙間５３よりも、外壁材１１の裏合決部１３の見込み面部１３ｄ側に配置されることとする。   Further, as shown in FIGS. 2 and 4A, the packing material 51q is arranged on the prospective surface portion 13d side of the back-to-back determination portion 13 of the outer wall material 11 with respect to the corner gap 53.

これにより、パッキン材５１ｑが角部隙間５３から奥まった位置に配置され、角部隙間５３からパッキン材５１ｑが見えてしまうことを防止できる。   Thereby, the packing material 51q is disposed at a position deeper from the corner gap 53, and the packing material 51q can be prevented from being seen from the corner gap 53.

さらに、以上に説明した構成は、図８（Ａ）に示すように袖壁１００を構成する場合や、図８（Ｂ）に示すように柱２００（門柱、ポーチ柱）などの外壁材構造物を構成する場合に適用することができる。なお、図８（Ａ）（Ｂ）では、パッキン材等の内部構造を一部省略した概略構造が示されている。   Furthermore, the structure demonstrated above is the case where the sleeve wall 100 is comprised as shown to FIG. 8 (A), or outer wall material structures, such as pillar 200 (a gate pillar, a porch pillar), as shown to FIG. 8 (B). It can be applied to the case of configuring. 8A and 8B show a schematic structure in which a part of the internal structure such as the packing material is omitted.

図９は、図８（Ａ）の袖壁１００の端部の部分拡大図であり、袖壁１００において、躯体の一部を構成する縦枠２（スタッド）（柱体を構成する角材）の両側には、構造用合板３，３が付設され、構造用合板３，３の表面に透湿防水シート５が貼設される。   FIG. 9 is a partial enlarged view of the end portion of the sleeve wall 100 of FIG. 8A. In the sleeve wall 100, the vertical frame 2 (stud) (a square member constituting the column) constituting a part of the casing. On both sides, structural plywood 3 and 3 are attached, and a moisture-permeable waterproof sheet 5 is stuck on the surface of the structural plywood 3 and 3.

The upper edge portions of the outer wall materials 11 and 11 ′ are fixed to the structural plywood 3 and 3 via fixing metal fittings 41 and 42, respectively.

固定金具４１，４２は、外壁材１１，１１’と透湿防水シート５の間に間隔を形成することで、外壁材１１，１１’の裏側に通気層８を形成する。   The fixing brackets 41 and 42 form a ventilation layer 8 on the back side of the outer wall materials 11 and 11 ′ by forming a space between the outer wall materials 11 and 11 ′ and the moisture-permeable waterproof sheet 5.

外壁材１１，１１’の側端部１２，１２’は、縦枠２の位置より一側方向に突出され、側端部１２，１２’の両端部の間の開口を塞ぐように外壁材２１が配設される。外壁材２１は、固定金具４３を介して縦枠２に固定される。   The side wall portions 12 and 12 ′ of the outer wall materials 11 and 11 ′ are protruded in one direction from the position of the vertical frame 2, and the outer wall material 21 is closed so as to close the opening between both ends of the side wall portions 12 and 12 ′. Is disposed. The outer wall material 21 is fixed to the vertical frame 2 via a fixing bracket 43.

外壁材１１の側端部１２と、外壁材２１の一方の側端部２２（図において右側の側端部）は、互いに隣接して配置され、接合角部６Ａが構成される。側端部１２，２２の裏面側には、それぞれ裏合決部１３，２３が形成されており、裏合決部１３，２３が互いに対向して配置され、平面視において略矩形の縦溝空間３０が形成される。   The side end portion 12 of the outer wall material 11 and one side end portion 22 (right side end portion in the figure) of the outer wall material 21 are disposed adjacent to each other, and a joining corner portion 6A is configured. Back-side determination portions 13 and 23 are formed on the back surfaces of the side end portions 12 and 22, respectively. The back-side determination portions 13 and 23 are arranged to face each other, and are substantially rectangular vertical groove spaces in plan view. 30 is formed.

接合角部６Ａにおいて、外壁材１１，２１の裏側には、外壁材１１，２１を接合する出隅接合部材５０（出隅ジョイナー）が配設される。出隅接合部材５０の構造は、図３に示すものと同様の構造を有してなるものである。   In the joining corner portion 6A, an out-corner joining member 50 (out-corner joiner) for joining the outer wall materials 11 and 21 is disposed on the back side of the outer wall materials 11 and 21. The projecting corner joining member 50 has a structure similar to that shown in FIG.

出隅接合部材５０は、スペーサー３２を介して構造用合板３や縦枠２に留め付けられ、出隅接合部材５０にて、外壁材１１，２１の側端部１２，２２の位置決めや、外壁材の裏側への水の浸入の防止や、排水が行われる。   The projecting corner joining member 50 is fastened to the structural plywood 3 and the vertical frame 2 via the spacer 32, and the projecting corner joining member 50 positions the side end portions 12 and 22 of the outer wall materials 11 and 21, and the outer wall. Prevention of water intrusion into the back side of the material and drainage.

また、接合角部６Ａにおいて、出隅接合部材５０の一部を構成する縦片部５１ｅが、一方の外壁材１１の裏合決部１３と、他方の外壁材２１の裏合決部２３の間の縦溝空間３０内に配設される。   In addition, in the joining corner portion 6A, the vertical piece portion 51e that constitutes a part of the protruding corner joining member 50 is formed between the back decision portion 13 of one outer wall material 11 and the back decision portion 23 of the other outer wall material 21. It is arrange | positioned in the longitudinal groove space 30 between.

この接合角部６Ａの構成は、もう一方の外壁材１１’と外壁材１２の接合角部分６Ｂにおいても同様に実現される。   The configuration of the joining corner portion 6A is similarly realized in the joining corner portion 6B of the other outer wall member 11 'and the outer wall member 12.

そして、接合角部６Ａ，６Ｂにおいても、上述した出隅部と同様の構成が実現される。即ち、図４（Ａ）（Ｂ）に示されるように、各外壁材１１,２１の側端部１２,２１には、それぞれ裏合決部１３,２３が形成され、裏合決部１３,２３は、平面視において外壁材の厚み方向の縦面を構成する見込み面部１３ｄ,２３ｄと、平面視において見込み面部１３ｄ,２３ｄと直交する縦面を構成する裏面部１３ｅ,２３ｅと、を有し、裏面部１３ｅ,２３ｅの幅寸法Ｗｅは、見込み面部１３ｄ,２３ｄの幅寸法Ｗｄよりも小さく構成され、一方の外壁材１１の側端部１２の側端面１２ｍは、他方の外壁材２１の裏面部２３ｅに対向するように配置され、側端面１２ｍと他方の外壁材２１の裏面部２３ｅの間には、角部隙間５３が形成される、構成が実現されることとする。   In the joint corners 6A and 6B, the same configuration as that of the above-described protruding corner is realized. That is, as shown in FIGS. 4 (A) and 4 (B), back end determination portions 13 and 23 are formed on the side end portions 12 and 21 of the outer wall materials 11 and 21, respectively. 23 includes prospective surface portions 13d and 23d that constitute vertical surfaces in the thickness direction of the outer wall material in plan view, and back surface portions 13e and 23e that constitute vertical surfaces orthogonal to the prospective surface portions 13d and 23d in plan view. The width dimension We of the back surface portions 13e and 23e is configured to be smaller than the width dimension Wd of the prospective surface portions 13d and 23d, and the side end surface 12m of the side end portion 12 of one outer wall material 11 is the back surface of the other outer wall material 21. It is arranged so as to face the portion 23e, and a configuration in which a corner gap 53 is formed between the side end surface 12m and the back surface portion 23e of the other outer wall member 21 is realized.

これにより、地震発生時には、一方の外壁材１１の見込み面部１３ｄが他方の外壁材２１の裏面２１ａに突き当たるため、一方の外壁材１１の側端部１２の側端面１２ｍが外壁材２１に突き当たることがなく、肉厚が薄い側端部１２について損傷の発生を防止できる。   Accordingly, when an earthquake occurs, the prospective surface portion 13d of one outer wall member 11 abuts against the back surface 21a of the other outer wall member 21, so that the side end surface 12m of the side end portion 12 of one outer wall member 11 abuts against the outer wall member 21. The occurrence of damage to the side end portion 12 having a small thickness can be prevented.

そして、以上の構成により、次の構成が実現される。
即ち、図８（Ａ）及び図９に示すように、外壁材を用いて構成される袖壁１００（外壁材構造物）において、
少なくとも三枚の外壁材を有し、
一つの外壁材２１と、一つの外壁材２１の一端と直交して接合される外壁材１１と、の間で構成される接合角部６Ａと、
一つの外壁材２１と、一つの外壁材２１の他端と直交して接合される外壁材１１’と、の間で構成される接合角部６Ｂと、
において、本発明の出隅部の構造が構成されるものとしている。 The following configuration is realized by the above configuration.
That is, as shown in FIG. 8 (A) and FIG. 9, in the sleeve wall 100 (outer wall material structure) configured using the outer wall material,
Having at least three outer wall materials,
6A of joining corner parts comprised between one outer wall material 21 and the outer wall material 11 joined orthogonally with the end of one outer wall material 21,
A joining corner portion 6B configured between one outer wall member 21 and an outer wall member 11 ′ joined orthogonally to the other end of the one outer wall member 21;
The structure of the protruding corner of the present invention is configured.

また、図８（Ｂ）に示すように、外壁材を用いて構成される門柱などの柱２００（外壁材構造物）において、
少なくとも三枚の外壁材を有し、
一つの外壁材２１と、一つの外壁材２１の一端と直交して接合される外壁材１１と、の間で構成される接合角部６Ａと、
一つの外壁材２１と、一つの外壁材２１の他端と直交して接合される外壁材１１’と、の間で構成される接合角部６Ｂと、
において、本発明の出隅部の構造が構成されるものとしている。 In addition, as shown in FIG. 8B, in a pillar 200 (outer wall material structure) such as a gate pillar configured using an outer wall material,
Having at least three outer wall materials,
6A of joining corner parts comprised between one outer wall material 21 and the outer wall material 11 joined orthogonally with the end of one outer wall material 21,
A joining corner portion 6B configured between one outer wall member 21 and an outer wall member 11 ′ joined orthogonally to the other end of the one outer wall member 21;
The structure of the protruding corner of the present invention is configured.

なお、この柱２００では、合計４枚の外壁材を平面視で方形状をなす様に配置することで、合計４箇所に接合角部６Ａ〜６Ｄが現れることになる。   In this column 200, joint corners 6A to 6D appear in a total of four places by arranging a total of four outer wall members in a square shape in plan view.

以上のように、本発明は、２枚の外壁材を直交配置してなる出隅部のみならず、外壁材を用いて構成される袖壁や柱（門柱、ポーチ柱）などの外壁材構造物についても幅広く適用することができる。   As described above, the present invention provides an outer wall material structure such as a sleeve wall or a column (a gate column, a porch column) formed using an outer wall material as well as a protruding corner portion formed by orthogonally arranging two outer wall materials. It can be widely applied to objects.

そして、この構造によれば、例えば、図８（Ａ）の構成であれば、二つの外壁材１１，１１‘の間の空間を蓋をするように外壁材２１を施工することが可能であり、これにより、躯体の一部を構成する縦枠２や、外壁材１１，１１‘の施工の精度が悪く、これらの他の部材に施工のやり直しが必要になる場合があっても、柔軟に対応することができる。つまり、外壁材２１のみの取り付け、取り外しが可能な構成であるため、施工性に優れた構成が実現できる。   And according to this structure, for example, if it is the structure of FIG. 8 (A), it is possible to construct the outer wall material 21 so as to cover the space between the two outer wall materials 11, 11 ′. Thus, even if the accuracy of the construction of the vertical frame 2 constituting the part of the housing and the outer wall materials 11 and 11 ′ is poor and the other members may need to be reworked, it is flexible. Can respond. That is, since only the outer wall material 21 can be attached and detached, a construction excellent in workability can be realized.

また、例えば、図８（Ａ）の構成であれば、袖壁端部において特に目立ちやすい外壁材２１に縦目地が存在せず、袖壁１００の正面に縦目地の存在しない意匠性の高い納まりが実現できる。このように、外壁材２１は、袖壁１００の正面を構成するための袖壁用サイディング（袖壁用外壁材）として好適に適用することができる。   Further, for example, in the configuration of FIG. 8A, there is no vertical joint in the outer wall material 21 that is particularly conspicuous at the end portion of the sleeve wall, and there is no long vertical joint in the front of the sleeve wall 100, and the design has high design. Can be realized. Thus, the outer wall material 21 can be suitably applied as a sleeve wall siding (sleeve wall outer wall material) for constituting the front surface of the sleeve wall 100.

また、図８（Ａ）（Ｂ）の構成において使用する出隅接合部材５０について、例えば、肉厚を厚くするなどして出隅接合部材５０の剛性を向上させることで、図６及び図７に示す横ずれ防止金具６２の機能を、出隅接合部材５０にて担保させることが可能となる。   8A and 8B, for example, by increasing the rigidity of the protruding corner joining member 50 by increasing the thickness thereof, for example, FIG. 6 and FIG. It is possible to secure the function of the lateral displacement prevention fitting 62 shown in FIG.

即ち、図４（Ａ）に示すように、出隅接合部材５０の縦片部５１ｅを裏合決部２３の見込み面部２３ｄに当接させることで、外壁材２１の矢印Ｘ２軸方向の横ずれを防止するものである。   That is, as shown in FIG. 4 (A), by causing the vertical piece portion 51e of the protruding corner joining member 50 to abut on the prospective surface portion 23d of the back-to-back determination portion 23, the lateral displacement of the outer wall material 21 in the direction of the arrow X2 is prevented. It is to prevent.

このように、出隅接合部材５０（縦片部５１ｅ）の剛性を向上させることにより、出隅接合部材５０によって外壁材２１の横ずれ防止をすることは、図１、図２に示す出隅部の構造においても同様に適用することができる。即ち、図１において、横ずれ防止金具６２の使用を省略し、出隅接合部材５０によって外壁材２１の横ずれ防止を図るものである。なお、剛性を向上した出隅接合部材５０（縦片部５１ｅ）と、横ずれ防止金具６２を併用することも当然に可能である。   Thus, by preventing the lateral displacement of the outer wall material 21 by the protruding corner bonding member 50 by improving the rigidity of the protruding corner bonding member 50 (vertical piece portion 51e), the protruding corner portion shown in FIGS. The same can be applied to the above structure. That is, in FIG. 1, the use of the lateral displacement prevention metal fitting 62 is omitted, and the lateral displacement of the outer wall material 21 is prevented by the protruding corner joining member 50. Of course, it is also possible to use the protruding corner joining member 50 (longitudinal piece 51e) with improved rigidity and the lateral shift prevention fitting 62 in combination.

本発明の構成は、窯業サイディングなどの板状の外壁材を用いる場合において、出隅部を構成する場合に広く適用することができる。   The configuration of the present invention can be widely applied to the case where the protruding corner portion is configured in the case where a plate-like outer wall material such as ceramic siding is used.
