Description

本発明は、建物の出隅や入隅の外壁工事において、外壁材として使用されるサイディングボードをシーリング材無しで接合する、いわゆるシーリングレス工法において使用できる建物外壁の接合具、該接合具を備えた建物外壁の接合構造及び該接合構造を構築する際に実行される建物外壁の接合方法に関する。   The present invention provides a joint for a building outer wall that can be used in a so-called sealing-less method for joining a siding board used as an outer wall material without a sealing material in exterior wall construction at the corner of a building or in a corner, and the joint. The present invention relates to a building outer wall joining structure and a building outer wall joining method executed when constructing the joint structure.

建物の外壁工事等を行う場合には、下記の特許文献１に開示されているようなサイディングボードが広く使用されている。サイディングボードとしては多種のデザイン、質感、色のものが用意されており、また、建築構造躯体の壁面部を外装するのに使用される平面部用サイディングボードの他、建築構造躯体の出隅と入隅を含むコーナー部を外装するのに使用されるコーナー部用のサイディングボードがある。
そして、このようなサイディングボードを使用して建物の外壁工事等を行う場合には、隣り合うサイディングボード間にできる隙間（目地）にシーリング材を充填してサイディングボードを接合する下記の特許文献１に示すようなシーリング工法が従来から多く行われている。しかし、近時は施工のやり易さと施工後の建物外壁の外観品質が良いことが注目されて、上記目地部分の内方に専用の接合金物を取り付けることで止水性を高めてサイディングボードをシーリング材無しで接合する、シーリングレス工法が主流になってきている。 When building the outer wall of a building or the like, a siding board as disclosed in Patent Document 1 below is widely used. Various types of siding boards are available in various designs, textures and colors. In addition to the siding boards for flat surfaces used for exterior wall surfaces of building structures, the corners of building structures There is a corner siding board that is used to coat the corner including the corner.
When such a siding board is used to construct an outer wall of a building or the like, a sealing material is filled in a gap (joint) formed between adjacent siding boards and the siding boards are joined together. Many sealing methods as shown in Fig. 1 have been conventionally performed. However, recently it has been noticed that the construction is easy and the exterior quality of the exterior wall after construction is good, and the siding board is sealed by increasing the water-stopping property by attaching a dedicated joint to the inside of the joint. Sealing-less methods of joining without materials are becoming mainstream.

また、上記目地部分に取り付けられる接合金物の一例として図７に示すようにハット型の形状をした「ハット型ジョイナー」と呼ばれている接合金物１０３がある（下記特許文献１の図８にも開示されている）。そして、この接合金物１０３は、接合するサイディングボード１０１、１０２の突合わせ部の内方に「しゃくり」と呼ばれる凹部１０４を形成し、該凹部１０４を利用して取り付けられる。
具体的には、図７に示すように上記凹部１０４に嵌まる内部に通気口１０５が形成された嵌合凸部１０６と、木材下地１０７等を介して建築構造躯体１０８の表面側の壁面部に取り付けられる取付け座板１０９と、を一体に形成することによってこの接合金物１０３は構成されている。そして、建物の出隅や入隅では、二枚の平面部用サイディングボードと一枚のコーナー部用サイディングボードとが接合されるため構造上極めて接近した位置に目地部分が複数でき、これら複数の目地部分ごとに複数の接合金物１０３が各別に使用されていた。 Further, as an example of the metal fitting attached to the joint portion, there is a metal fitting 103 called a “hat-shaped joiner” having a hat shape as shown in FIG. 7 (also in FIG. 8 of Patent Document 1 below). Disclosed). And this metal fitting 103 forms the recessed part 104 called a "shear" in the inside of the butt | matching part of the siding boards 101 and 102 to join, and it attaches using this recessed part 104. FIG.
Specifically, as shown in FIG. 7, a fitting convex portion 106 in which a vent hole 105 is formed inside the concave portion 104 and a wall surface portion on the surface side of the building structural frame 108 through a wood base 107 and the like. The joint fitting 103 is formed by integrally forming a mounting seat plate 109 attached to the base plate. And, at the corner of the building and the corner of the building, two plane siding boards and one corner siding board are joined, so there are multiple joints at positions that are very close in structure. A plurality of metal fittings 103 were used for each joint portion.

特開平１１−３１１０１０号公報Japanese Patent Laid-Open No. 11-311010

このように、建物の出隅や入隅の外壁工事では、構造上複数存在する目地部分が極めて接近した位置に存在しているにも拘わらず各目地ごとに複数の接合金物を個別に使用して複数回、接合金物の手間のかかる取付け作業を行わなければならなかった。
また、上述したシーリングレス工法では、施工が比較的容易で施工後の建物外壁の外観が優れる反面、建物内への雨水等の浸入が問題になる。そして、サイディングボードの内側に雨水等が浸入して木材下地に達し、その内部の建築構造躯体に染み込んだ場合には建築構造躯体に大きなダメージを与えることから、上記目地部分には高い止水性が常に求められている。 In this way, in exterior wall construction at the corners and corners of buildings, a plurality of joint hardware is used individually for each joint even though there are multiple joints in the structure. For this reason, it has been necessary to perform a time-consuming installation work of the joint hardware several times.
In addition, in the above-described sealingless method, the construction is relatively easy and the appearance of the outer wall of the building after construction is excellent, but intrusion of rainwater or the like into the building becomes a problem. And if rainwater penetrates into the inside of the siding board and reaches the timber base and soaks into the building structure frame inside it, the building structure frame will be seriously damaged. Always sought.

本発明はこのような点に基づいてなされたもので、その目的とするところは施工が容易で施工後の外観に優れるシーリングレス工法に対応でき、特に建物の出隅と入隅での外壁工事における作業性の向上と目地部分の止水性の向上とを図ることができる、安価で施工が容易で部品点数の少ない建物外壁の接合具、該接合具を備えた建物外壁の接合構造及び該接合構造を構築する際に実行される建物外壁の接合方法を提供することにある。   The present invention has been made on the basis of such points, and the object of the present invention is to cope with a sealingless construction method that is easy to construct and excellent in appearance after construction. In addition, it is possible to improve the workability and the water-stopping performance of the joint portion, and it is an inexpensive and easy-to-construction and low-part-number joint building wall joint, a building exterior wall joint structure including the joint, and the joint An object of the present invention is to provide a method for joining outer walls of a building which is executed when a structure is constructed.
