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、出隅部の外側部分に配置される出隅カバーを内側から受けるための受け部材に関する。   The present invention relates to a technology for forming an outer wall with ceramic siding (outer wall material), and more particularly, to a receiving member for receiving, from the inside, a protruding corner cover arranged at an outer portion of a protruding corner portion. About.

従来、例えば特許文献1に開示されるように、板状の外壁材(金属サイディング)を直交して配置し、その角部にて外壁の出隅部を構成する技術が知られている。出隅部においては、外壁材の間に隙間が形成されるため、この隙間を埋めるために、出隅カバー(化粧板)が取り付けられる。   BACKGROUND ART Conventionally, as disclosed in Patent Document 1, for example, a technique is known in which a plate-shaped outer wall material (metal siding) is arranged orthogonally, and a corner of the outer wall is formed at the corner. Since a gap is formed between the outer wall materials at the protruding corner, a protruding corner cover (decorative board) is attached to fill the gap.

そして、この出隅カバーは出隅部の外側部分に配置されるものであり、この出隅カバーを内側から保持するために、躯体側となる下地材には受け部材(取付部材)が取り付けられる。この受け部材には、二本の係止突条を対向してなる嵌合凹部が形成され、この嵌合凹部に出隅カバーに設けた係止突条を嵌入することで、出隅カバーが受け部材に嵌合固定される構成としている。   The protruding corner cover is arranged on an outer portion of the protruding corner portion. In order to hold the protruding corner cover from the inside, a receiving member (mounting member) is attached to the base material on the skeleton side. . The receiving member is formed with a fitting recess formed by opposing two locking protrusions. The fitting protrusion provided on the corner cover is fitted into the fitting recess, so that the protruding corner cover is formed. It is configured to be fitted and fixed to the receiving member.

特開平8−199785号公報JP-A-8-199785

図7は、特許文献1と同様の構成例を示すものであり、出隅カバー91の係止突条92が出隅カバー93の係止突条94の内側に係止される構成としている。係止突条94は、L字状の固定片95の角部の位置において、斜略45度の方向に突出される。   FIG. 7 shows a configuration example similar to that of Patent Document 1, in which a locking ridge 92 of a protruding corner cover 91 is locked inside a locking ridge 94 of a protruding corner cover 93. The locking ridge 94 projects obliquely at an angle of approximately 45 degrees at the corner of the L-shaped fixing piece 95.

ここで、外壁材90の端面90aは、出隅カバー93の係止突条94の基端部に当接する位置まで寄せることができるが、最も寄せた場合であっても、出隅部の直交点P(外壁材90の表面の延長線が交差する点)から、幅X1だけ離れた位置に配置されてしまう。   Here, the end face 90a of the outer wall material 90 can be brought to a position where it comes into contact with the base end of the locking ridge 94 of the come-out corner cover 93. It is arranged at a position away from the point P (the point where the extension line of the surface of the outer wall material 90 intersects) by the width X1.

そして、出隅カバー91のカバー表面91aにより、外壁材90との十分な重なり代X2を確保しようとすると、必然的にカバー表面91aの幅X3が広くなってしまう。   Then, if an attempt is made to secure a sufficient overlap margin X2 with the outer wall material 90 by the cover surface 91a of the protruding corner cover 91, the width X3 of the cover surface 91a necessarily increases.

しかし、幅X3が広くなるほど出隅カバー91が目立ってしまうことになり、外壁材90との表面の質感の違いも相まって、意匠性を損なってしまうことがある。つまり、出隅部における外壁材90の連続性が顕著に損なわれてしまうことになる。特に、外壁材90が窯業系サイディングで構成される場合において、金属製の出隅カバー91を使用する場合には、その表面の質感が顕著に異なり、意匠性を損ない易くなってしまう。   However, the larger the width X3, the more prominent the corner cover 91 becomes, and the difference in the texture of the surface with the outer wall material 90 may result in a loss of design. That is, the continuity of the outer wall material 90 at the protruding corner is significantly impaired. In particular, in the case where the outer wall material 90 is made of ceramic siding, when the metal corner cover 91 is used, the texture of the surface is significantly different, and the design is likely to be impaired.

そこで、本発明は以上の問題に鑑み、出隅部において外壁材の端面同士をより近づけて配置することを可能とし、これにより、出隅カバーの幅を少なく抑えることを可能とするための新規な技術を提案する。   In view of the above problems, the present invention makes it possible to arrange the end surfaces of the outer wall material closer to each other at the protruding corner portion, thereby making it possible to reduce the width of the protruding corner cover. We propose new technologies.

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.

本発明の効果として、以下に示すような効果を奏する。   The present invention has the following effects.

即ち、請求項1に記載の発明においては、外壁材の縦端面と嵌合部が干渉する位置を、突条部が無い場合の干渉位置と比較して出隅部の直交点(外壁材の表面の延長線が交差する点)側により近づけることができ、幅の狭いカバー面部を用いても十分な重なり代を確保することができる。そして、幅の狭いカバー面部を用いることが可能となることで、出隅カバーが目立ち難い構成が実現できる。
また、施工時において、壁端面当接部に外壁材の縦端面を当接させるようにして、外壁材の位置決めを行うことが可能となる。
That is, in the invention described in claim 1, the position where the vertical end face of the outer wall material and the fitting portion interfere with each other is compared with the interference position where there is no ridge portion, and the orthogonal point of the projected corner portion (the outer wall material This can be made closer to the side where the extension line of the surface intersects), and a sufficient overlapping margin can be secured even if a narrow cover surface is used. And since it becomes possible to use the cover surface part with a narrow width | variety, the structure in which an outside corner cover is not conspicuous can be realized.
Further, at the time of construction, the outer wall material can be positioned by bringing the vertical end surface of the outer wall material into contact with the wall end surface contact portion.

また、請求項に記載の発明においては、外壁材を下地材に近づけた場合、水返し突部に外壁材の裏面が当接することになり、突条部の先端部、即ち、壁端面当接部の分岐点に、外壁材の裏側の角部が突き当たることを防止できる。そして、これにより、外壁材の裏側の角部が分岐点に直接的に突き当たることによる分岐点を基点とした壁端面当接部の破断を防止することができる。 According to the second aspect of the present invention, when the outer wall material is brought close to the base material, the back surface of the outer wall material comes into contact with the water return projection, that is, the tip of the ridge, that is, the wall end surface contact. The corner on the back side of the outer wall material can be prevented from hitting the branch point of the contact portion. Thus, it is possible to prevent breakage of the wall end surface contact portion starting from the branch point due to the back corner of the outer wall material directly abutting on the branch point.

In addition, it is possible to close the opening of the gap formed at the joint between the outer wall materials adjacent to each other vertically and opened in the lateral direction from the side by this wall end face abutting part, and to prevent water intrusion through the gap from the wall end face. This can be effectively prevented by the contact portion.

また、請求項に記載の発明においては、幅の狭いカバー面部を用いても十分な重なり代を確保することができ、出隅カバーが目立ち難い構成が実現できる。
According to the fourth aspect of the present invention, a sufficient overlapping margin can be secured even if a narrow cover surface portion is used, and a configuration in which the corner cover is less noticeable can be realized.

Be composed. The protruding corner cover 20 can be made of an extruded product such as aluminum or resin, or a sheet metal processed product.

本実施例では、中心線Cを基準に線対称となる形状にて構成されており、中心線Cと直交する角カバー面部22aと、外壁材4,4の表面4c,4cに対向させるように角カバー面部22aの両側から延びるカバー面部22b,22bとを有している。   In the present embodiment, it is configured in a shape that is symmetrical with respect to the center line C, and is opposed to the corner cover surface portion 22a orthogonal to the center line C and the surfaces 4c, 4c of the outer wall materials 4, 4. Cover surface portions 22b, 22b extending from both sides of the corner cover surface portion 22a.

角カバー面部22aの内側には、係止突条25,25が互いに平行となるように配置される。係止突条25の先端部には、係止部25aが形設され、この係止部25aが受け部材30の係止突条35に形成された係止部35a(図3(B))に係止される。両係止部25a,35aは、係止突条25を押し込む方向の移動は許容し、その逆方向の移動は許容しないように構成されており、係止突条25の抜け止めとして機能する。   The locking projections 25 are arranged inside the corner cover surface portion 22a so as to be parallel to each other. A locking portion 25a is formed at the tip of the locking ridge 25, and the locking portion 25a is formed on the locking ridge 35 of the receiving member 30 (FIG. 3B). Is locked. The locking portions 25a and 35a are configured to allow movement in the direction of pushing the locking ridge 25 but not allow movement in the opposite direction, and function as a stopper for the locking ridge 25.

また、係止突条35側の係止部35aは、係止突条35の突出方向において複数個所に形成されており、係止部25aの係止箇所を複数個所から可能に構成される。本実施例の係止部35aでは、微小の突条を複数列有して構成される。   Further, the locking portion 35a on the locking ridge 35 side is formed at a plurality of positions in the projecting direction of the locking ridge 35, and the locking portion of the locking portion 25a can be configured from a plurality of positions. The locking portion 35a of the present embodiment is configured to have a plurality of rows of minute protrusions.

出隅カバー20を取り付ける際には、カバー面部22bを外壁材4の表面4cに当接するまで出隅カバー20全体を押し込み、係合部21,31同士を嵌合することで、取り付けが完了できる。この際、係止突条25(係止部25a)が係止突条35(係止部35a)のいずれかの箇所で係止され、その係止が維持されることで、カバー面部22bを外壁材4の表面4cに当接させた状態を維持できる。なお、カバー面部22bと外壁材4の表面4cの間にパッキンなどが挟装される構成としてもよい。   When attaching the corner cover 20, the entire corner cover 20 is pushed in until the cover surface 22 b contacts the surface 4 c of the outer wall material 4, and the engagement portions 21 and 31 are fitted together to complete the attachment. . At this time, the locking ridge 25 (locking portion 25a) is locked at any position of the locking ridge 35 (locking portion 35a), and the locking is maintained, so that the cover surface portion 22b is fixed. The state in which the outer wall member 4 is in contact with the surface 4c can be maintained. It should be noted that packing or the like may be interposed between the cover surface portion 22b and the surface 4c of the outer wall material 4.

以上の構成において、以下に説明する特徴的な構成を実現することができる。
まず、図1乃至図4に示すように、
出隅部1にて互いに直交して隣接する外壁材4,4の間の隙間4sを外側から覆い隠す出隅カバー20を、外壁材4,4の内側から受けるための受け部材30であって、
下地材(躯体2(胴縁5))に固定されるためのベース部32と、
ベース部32から隙間4s側に向かう方向に突設される突条部33と、
突条部33の突出端側に設けられ、出隅カバー20を嵌合させるための嵌合部31と、
を有する受け部材30とする。
In the above configuration, the characteristic configuration described below can be realized.
First, as shown in FIGS. 1 to 4,
A receiving member 30 for receiving, from the inside of the outer wall members 4, the outside corner cover 20, which covers the gap 4 s between the outer wall members 4, 4 orthogonally adjacent to each other at the outside corner portion 1 from outside. ,
A base portion 32 for being fixed to the base material (the frame 2 (the body edge 5));
A ridge 33 protruding from the base 32 in a direction toward the gap 4s;
A fitting portion 31 provided on the protruding end side of the ridge portion 33 for fitting the protruding corner cover 20;
The receiving member 30 has the following.

この構成では、図4に示すように、突条部33の突出方向Tにおいて、突条部33の寸法33xだけベース部32から離れた位置に出隅カバー20を嵌合するための嵌合部31を配置させることが可能となる。これにより、外壁材4の縦端面4aと嵌合部31が干渉する位置L1を、突条部33が無い場合の干渉位置L2と比較して出隅部の直交点P(外壁材4の表面の延長線が交差する点)側(矢印Xp方向)により近づけることができ、幅の狭いカバー面部22bを用いても十分な重なり代X2を確保することができる。そして、幅の狭いカバー面部22bを用いることが可能となることで、出隅カバー20が目立ち難い構成が実現できる。   With this configuration, as shown in FIG. 31 can be arranged. Thereby, the position L1 where the vertical end surface 4a of the outer wall material 4 and the fitting portion 31 interfere with each other is compared with the interference position L2 where the ridge 33 is not provided, and the orthogonal point P (the surface of the outer wall material 4) (The point where the extension lines intersect) crosses (in the direction of the arrow Xp), and a sufficient overlap margin X2 can be ensured even if the cover surface portion 22b having a small width is used. And since it becomes possible to use the cover surface part 22b with a small width | variety, the structure in which the corner cover 20 is not conspicuous can be realized.

なお、仮に、突条部33を設けない場合には、外壁材4の縦端面4aと嵌合部31は干渉位置L2にて干渉することになる。このため、重なり代X2を確保する場合には、位置L3の位置までカバー面部22bを構成する必要があり、幅X4だけカバー面部22bが広くなって、出隅カバー20が目立つ構成となってしまう。換言すれば、本発明の構成によれば、従来構造と比較して、幅X4だけ狭いカバー面部22bを有する出隅カバー20を構成することが可能となる。   If the ridge portion 33 is not provided, the vertical end surface 4a of the outer wall member 4 and the fitting portion 31 interfere at the interference position L2. For this reason, in order to secure the overlap margin X2, it is necessary to configure the cover surface portion 22b up to the position L3, and the cover surface portion 22b is widened by the width X4, so that the protruding corner cover 20 becomes conspicuous. . In other words, according to the configuration of the present invention, it is possible to configure the protruding corner cover 20 having the cover surface portion 22b narrower by the width X4 than the conventional structure.

また、図4に示すように、嵌合部31は、突条部33の先端部33p(分岐点34A)から二つに分岐してなる一対の壁端面当接部34,34であって、外壁材4の縦端面4aが当接される壁端面当接部34,34を有する、構成とする。   Further, as shown in FIG. 4, the fitting portion 31 is a pair of wall end surface contact portions 34, 34 branched from a tip portion 33 p (branch point 34 A) of the ridge portion 33, It has the structure which has the wall end surface contact parts 34 and 34 which the vertical end surface 4a of the outer wall material 4 contacts.

これにより、施工時において、壁端面当接部34に外壁材4の縦端面4aを当接させるようにして、外壁材4の位置決めを行うことが可能となる。   Thereby, at the time of construction, it is possible to position the outer wall material 4 such that the vertical end surface 4a of the outer wall material 4 abuts on the wall end surface contact portion 34.

また、図3(A)及び図5に示すように、ベース部32は、それぞれ下地材(躯体2(胴縁5))に固定され、互いに直交して角部32dを構成する板状の固定部32a,32aを有し、
角部32dに突条部33が構成され、
各固定部32a,32aにおいて角部32dと反対側の位置に外壁材4の裏面4b側に向けて突出される水返し突部32c,32cが設けられ、
固定部32aの表面32eに対する固定部32aの厚み方向Hにおいて、
水返し突部32cの突出寸法32hは、突条部33の突出寸法33hよりも大きく構成される、こととする。
例えば、突出寸法32hを突出寸法33hよりも、0.2mm〜5mm程度大きくする。
As shown in FIGS. 3A and 5, the base portion 32 is fixed to the base material (the frame 2 (body edge 5)), and is a plate-shaped fixing member that is orthogonal to each other and constitutes the corner portion 32 d. Parts 32a, 32a,
A ridge 33 is formed on the corner 32d,
Water return protrusions 32c, 32c projecting toward the back surface 4b side of the outer wall material 4 are provided at positions opposite to the corners 32d in the fixing portions 32a, 32a, respectively.
In the thickness direction H of the fixing portion 32a with respect to the surface 32e of the fixing portion 32a,
The projecting dimension 32h of the water return protrusion 32c is configured to be larger than the projecting dimension 33h of the ridge 33.
For example, the protrusion size 32h is set to be larger than the protrusion size 33h by about 0.2 mm to 5 mm.

これにより、仮に、図5の構成において、外壁材4を下地材(躯体2(胴縁5))に近づけて配置した場合、水返し突部32cに外壁材4の裏面4bが当接することになり、突条部33の先端部、即ち、壁端面当接部34,34の分岐点34Aに、外壁材4の裏側の角部4kが突き当たることを防止できる。そして、角部4kが分岐点34Aに直接的に突き当たることによる分岐点34Aを基点とした壁端面当接部34の破断を防止することができる。   Thereby, in the configuration of FIG. 5, if the outer wall material 4 is arranged close to the base material (the skeleton 2 (body edge 5)), the back surface 4b of the outer wall material 4 comes into contact with the water return protrusion 32c. That is, it is possible to prevent the corner 4k on the back side of the outer wall material 4 from abutting on the distal end portion of the ridge portion 33, that is, the branch point 34A of the wall end surface contact portions 34, 34. Further, it is possible to prevent the breakage of the wall end surface contact portion 34 starting from the branch point 34A due to the corner 4k directly abutting on the branch point 34A.

また、図4に示すように、壁端面当接部34,34は、縦方向に延びる板面にて構成され、外壁材4,4の縦端面4aと面接触すべく構成される。   As shown in FIG. 4, the wall end surface contact portions 34, 34 are formed of plate surfaces extending in the vertical direction, and are configured to make surface contact with the vertical end surfaces 4 a of the outer wall materials 4, 4.

これにより、外壁材4の縦端面4aと壁端面当接部34の間を通じた水の浸入を防止することができる。また、図6(A)(B)に示すように、上下に隣り合う外壁材4の接合部4Sにおいて横方向に開放される隙間4Mの開口を、この壁端面当接部34により横から塞ぐことが可能となり、隙間4Mを通じての水の浸入を壁端面当接部34によって効果的に防止できる。なお、図6(A)(B)の接合部4Sの例では、上下の合決部4d,4uを接合してなる合決接合により隙間4Mが構成される例としているが、このほかの接合形態においても、同様の効果を得ることができる。   Thereby, it is possible to prevent water from entering between the vertical end surface 4a of the outer wall material 4 and the wall end surface contact portion 34. As shown in FIGS. 6A and 6B, the opening of the gap 4M that is opened in the lateral direction at the joint 4S of the outer wall material 4 vertically adjacent to each other is closed from the side by the wall end surface contact portion 34. The intrusion of water through the gap 4M can be effectively prevented by the wall end face contact portion 34. In addition, in the example of the joining portion 4S in FIGS. 6A and 6B, the gap 4M is formed by the joint joining of the upper and lower joints 4d and 4u, but other joints are used. The same effect can be obtained in the embodiment.
