A seal member with high adhesion may be provided at the outdoor side end of the side edge.
本発明によれば、外壁の目地の位置でコストを抑えて容易に漏水を防止可能な外壁構造および外壁施工方法を提供することができる。 According to the present invention, it is possible to provide an outer wall structure and an outer wall construction method capable of easily preventing water leakage at a position of a joint of the outer wall while suppressing costs.
以下、図面に基づき、本発明の実施の形態について説明する。
図１は、本発明の実施の形態の（ａ）外壁構造を示す平面図、（ｂ）外壁構造の防水材を示す正面図である。
Hereinafter, an embodiment of the present invention will be described based on the drawings.
FIG. 1 is a plan view showing (a) an outer wall structure according to an embodiment of the present invention, and (b) a front view showing a waterproof material of the outer wall structure.
図１に示すように、外壁構造は、柱１と、胴縁２と、２つの外壁材３と、コーキング材４と、弾力性の防水材５とを有している。この外壁構造は、建築物に適用され、特に、木造住宅に適している。胴縁２は、耐水性、腐朽性の合成樹脂製木材から成る。胴縁２は、柱１より細い角柱状であって、柱１の屋外側側面１ａに釘などで固定されている。２つの外壁材３は、サイディングボードから成り、互いに隣接して胴縁２の屋外側側面２ａに留め金具６で固定されている。コーキング材４は、各外壁材３の間の目地７に充填され、目地７を塞いでいる。 As shown in FIG. 1, the outer wall structure includes a pillar 1, a body rim 2, two outer wall members 3, a caulking member 4, and an elastic waterproof member 5. This outer wall structure is applied to buildings, and is particularly suitable for wooden houses. The body rim 2 is made of water-resistant, decay-resistant synthetic resin wood. The body edge 2 has a prismatic shape thinner than the column 1 and is fixed to the outdoor side surface 1 a of the column 1 with a nail or the like. The two outer wall members 3 are made of a siding board and are fixed to each other on the outdoor side surface 2 a of the body rim 2 with fasteners 6 adjacent to each other. The caulking material 4 is filled in the joint 7 between the outer wall materials 3 to close the joint 7.
防水材５は、外壁材３とほぼ同じ長さの細長い金属製の板状であって、両側縁部５ａが折り返すよう内側に湾曲して厚さ方向にバネ弾性を有している。防水材５は、両側縁部５ａの中間位置に長さ方向に両端まで伸びる溝部５ｂを有している。溝部５ｂは、防水材５の両側縁部５ａの側に設けられ、胴縁２の幅と一致する幅を有している。防水材５は、溝部５ｂに胴縁２を嵌合させて柱１と胴縁２との間に挟まれ、胴縁２を挟む両側で両側縁部５ａを各外壁材３に弾力的に押し付けて密着させている。防水材５は、各外壁材３の上端から下端まで目地７の全体を覆うよう伸びている。 The waterproof material 5 is an elongated metal plate having substantially the same length as the outer wall material 3 and is curved inward so that both side edge portions 5a are folded back and has spring elasticity in the thickness direction. The waterproof material 5 has a groove 5b extending to both ends in the lengthwise direction at an intermediate position between the side edges 5a. The groove 5 b is provided on the side edge 5 a of the waterproof material 5 and has a width that matches the width of the body edge 2. The waterproof material 5 is inserted between the column 1 and the body edge 2 by fitting the body edge 2 to the groove 5b, and the both side edge portions 5a are elastically pressed against the outer wall members 3 on both sides sandwiching the body edge 2 It makes close contact. The waterproof material 5 extends so as to cover the entire joint 7 from the upper end to the lower end of each outer wall material 3.
この外壁構造を施工するには、まず、溝部５ｂに胴縁２を嵌合させ、防水材５を柱１の屋外側側面１ａと胴縁２との間に挟む。胴縁２を挟む両側で両側縁部５ａを屋外側に向けて配置し、胴縁２を柱１に釘などで固定する。次に、胴縁２の屋外側側面２ａに互いに隣接するよう２つの外壁材３を配置し、両側縁部５ａを各外壁材３に弾力的に押し付けて密着させて各外壁材３を胴縁２に留め金具６で固定する。各外壁材３の間の目地７をコーキング材４で塞ぐことにより、外壁構造を施工することができる。 In order to construct this outer wall structure, first, the trunk 2 is fitted in the groove 5 b, and the waterproof material 5 is sandwiched between the outdoor side surface 1 a of the column 1 and the trunk 2. The two side edges 5a are arranged on the outside on both sides of the body edge 2 and the body edge 2 is fixed to the column 1 with a nail or the like. Next, the two outer wall members 3 are disposed adjacent to the outer side surface 2a of the torso edge 2 so that the both side edge portions 5a are elastically pressed against the respective outer wall members 3 to closely contact each outer wall member 3 Fix it to 2 with fastener 6. By covering the joint 7 between the outer wall materials 3 with the caulking material 4, an outer wall structure can be constructed.
外壁構造および外壁施工方法では、防水材５が目地７を内側から挟んで両側縁部５ａを各外壁材３に弾力的に押し付けて密着させるため、コーキング材４が劣化して目地７から屋内側に漏水したとしても、防水材５で漏水を阻むことができる。このため、外壁材３の下側に透湿防水シートを設ける必要がなく、外壁の目地７の位置でコストを抑えて容易に漏水を防止することができる。 In the outer wall structure and the outer wall construction method, the waterproof material 5 sandwiches the joint 7 from the inside and elastically presses the side edges 5a against each outer wall material 3 so that the caulking material 4 deteriorates and the indoor side from the joint 7 deteriorates. Even if the water leaks, the waterproof material 5 can prevent the water leak. For this reason, it is not necessary to provide a moisture permeable waterproof sheet under the outer wall material 3, and the cost can be suppressed at the position of the joint 7 of the outer wall, and water leakage can be easily prevented.
