また、左側の上記側板部３５の前端には、左方に突出して接着剤３３を保持する接着剤保持部３２が上記ジョイナ３の上下方向全体に亘って形成されている。該接着剤保持部３２には、前方に開口して接着剤３３が充填される接着剤保持溝３２ａが形成されている。ここにおける接着剤３３は、外壁材４の背面に接着して、ジョイナ３と外壁材４とを接着固定することで、外壁材４の側端の固定強度を高めて浮き上がりを防ぐとともに防水性を高める。また、外壁材４の端部が接着剤３３を介してジョイナ３及び出隅用下地材１に強固に固定されているので、外壁材４が温度変化に伴って寸法変化しても、接着剤３３による固定がなされていない場合と比較して、左右方向へのズレが抑制されるため接合部の隙間が拡大せず、防水性を保持することが可能となる。   An adhesive holding portion 32 that protrudes to the left and holds the adhesive 33 is formed at the front end of the left side plate portion 35 over the entire vertical direction of the joiner 3. The adhesive holding portion 32 is formed with an adhesive holding groove 32 a that opens forward and is filled with the adhesive 33. Here, the adhesive 33 is bonded to the back surface of the outer wall material 4 to bond and fix the joiner 3 and the outer wall material 4, thereby increasing the fixing strength of the side end of the outer wall material 4 to prevent lifting and waterproofing. Increase. Moreover, since the edge part of the outer wall material 4 is being firmly fixed to the joiner 3 and the base material 1 for a corner by the adhesive agent 33, even if the outer wall material 4 changes in dimensions with a temperature change, the adhesive agent Compared with the case where the fixing by 33 is not performed, the displacement in the left-right direction is suppressed, so that the gap between the joint portions is not enlarged, and waterproofness can be maintained.

なお、接着剤３３は、接着剤保持溝３２ａのうち、上下に隣接する出隅材２，２同士の接合部及びその側方に位置する上下に隣接する外壁材４，４同士の接合部の近傍に位置する箇所には充填されていないことが好ましい。出隅材２や外壁材４を施工する際に接着剤３３が押圧されて出隅材２および外壁材４の接合部からはみ出るのを防ぐためである。   Note that the adhesive 33 is composed of a bonding portion between the protruding corner members 2 and 2 adjacent to each other in the adhesive holding groove 32a and a bonding portion between the upper and lower outer wall members 4 and 4 positioned on the side thereof. It is preferable that a portion located in the vicinity is not filled. This is to prevent the adhesive 33 from being pressed when the projecting corner member 2 or the outer wall member 4 is constructed and protruding from the joint between the projecting corner member 2 and the outer wall member 4.

上記の止水材３１は、予めジョイナ３に取り付けられた状態で工場出荷される。接着剤３３については施工現場において接着剤保持溝３２ａに充填される。なお、接着剤３３も上記止水材３１と同様に予めジョイナ３に取り付けられた状態で出荷されてもよい。   The water blocking material 31 is shipped from the factory in a state where it is attached to the joiner 3 in advance. The adhesive 33 is filled in the adhesive holding groove 32a at the construction site. Note that the adhesive 33 may also be shipped in a state in which it is attached to the joiner 3 in advance, similarly to the water blocking material 31.

出隅材２の左側及び後側には、平板状の外壁材４が配されるとともに、外壁材取付具６によって建物躯体の外面に固定される。ここにおける外壁材取付具６は、柱８の前側面８１に接するジョイナ３の左側に位置し、また、柱８の右側面８２に接するジョイナ３の後側に位置する。上記の出隅材取付具５と同様に、上下に並ぶように施工される外壁材４の上縁に設けられた裏実部４１の上端を支持片６１の突出端両端部に設けた下側折曲片６３に引っ掛けるとともに、この外壁材４の上方側に設置される他の外壁材４の下縁に設けられた係止溝４３に、斜め上方に突出する上側折曲片６２を係止させることで上方側の外壁材４の下端を固定する。この時、上方側の外壁材４の表面側の下縁に設けられた表実部４２が、下方の外壁材４の上縁の裏実部４１と合いじゃくりで接合されるために、上下に並ぶ外壁材４，４間の防水が図られる。なお、図１に図示する外壁材取付具６と、図２に図示する外壁材取付具６とは、形状が僅かに異なるが、その基本的な構造は、出隅材取付具５と略同一である。   A flat plate-like outer wall material 4 is disposed on the left side and the rear side of the protruding corner member 2 and is fixed to the outer surface of the building frame by an outer wall member attachment tool 6. Here, the outer wall material attachment 6 is located on the left side of the joiner 3 in contact with the front side surface 81 of the column 8 and on the rear side of the joiner 3 in contact with the right side surface 82 of the column 8. Similar to the above-mentioned corner fitting fixture 5, the upper side of the back solid part 41 provided at the upper edge of the outer wall material 4 constructed so as to be lined up and down is provided at the projecting end both ends of the support piece 61. While hooking on the bent piece 63, the upper bent piece 62 protruding obliquely upward is locked in the locking groove 43 provided on the lower edge of the other outer wall material 4 installed above the outer wall material 4. By doing so, the lower end of the upper outer wall member 4 is fixed. At this time, since the front solid part 42 provided on the lower edge of the surface side of the upper outer wall member 4 is joined to the rear solid part 41 of the upper edge of the lower outer wall member 4 in an overlapping manner, Waterproofing is achieved between the outer wall materials 4 and 4 arranged in line. The outer wall material fixture 6 shown in FIG. 1 and the outer wall material fixture 6 shown in FIG. 2 are slightly different in shape, but the basic structure thereof is substantially the same as the protruding corner material fixture 5. It is.

そして、出隅材２及び外壁材４を固定した時、上記各ジョイナ３の止水材３１，３１のうちの一方は、出隅材２の裏面に密着し、他方は外壁材４の裏面に密着し、出隅材２と外壁材４との突き合わせ面から背後側に浸入する雨水が左右に広がることを防止する。また、上記突き合わせ面の背後に浸入してきた雨水は、下側にも開口する凹溝３０によって下方へと流す。   When the protruding corner member 2 and the outer wall member 4 are fixed, one of the water stop materials 31, 31 of each joiner 3 is in close contact with the rear surface of the protruding corner member 2, and the other is on the rear surface of the outer wall member 4. It adheres closely and prevents the rainwater which infiltrates into the back side from the abutting surface of the protruding corner member 2 and the outer wall member 4 from spreading to the left and right. In addition, rainwater that has entered the back of the abutting surface flows downward by a concave groove 30 that also opens on the lower side.

出隅材２の側端部付近の裏実部２１上面及び外壁材４の側端部付近の裏実部４１上端には、水の横走りを防止するための止水材３６を取り付けておくのが好ましい。この止水材３６は、例えば、軟質塩化ビニル樹脂、ＥＰＤＭやクロロプレンシリコン等の軟質材からなり、外壁材４や出隅材２の上記上端における止水材３１が接する部分に位置しているか、この部分よりも出隅材２と外壁材４との突き合わせ面に近い位置にあることが好ましい。接合部に浸入した水を凹溝３０に導くことが可能となり、その結果、接合部に浸入した水が止水材３１の左右方向外側に流出するのを防止することができる。   A water stop material 36 for preventing lateral running of water is attached to the upper surface of the back solid portion 21 near the side end portion of the protruding corner member 2 and the upper end of the back solid portion 41 near the side end portion of the outer wall member 4. Is preferred. The water stop material 36 is made of a soft material such as soft vinyl chloride resin, EPDM, or chloroprene silicon, and is located at a portion where the water stop material 31 is in contact with the upper end of the outer wall member 4 or the protruding corner member 2; It is preferable to be at a position closer to the abutting surface between the protruding corner member 2 and the outer wall member 4 than this portion. It becomes possible to guide the water that has entered the joint portion to the concave groove 30, and as a result, it is possible to prevent the water that has entered the joint portion from flowing out to the outside in the left-right direction of the water stop material 31.

図３〜図５に他例を示す。基本的構成は上記の実施例で示したものと同じであるが、ジョイナ３における接着剤保持溝３２ａ及び接着剤保持溝３２ａに充填した接着剤３３を凹溝３０の開口部の左右両側（図示例では止水材保持溝３７ａよりも外側）に設けて、出隅材２の側端部の背面も接着固定するようにしている。この場合、外壁材４と出隅材２との間に隙間が生じてしまうおそれを更に少なくすることができる。   Other examples are shown in FIGS. Although the basic configuration is the same as that shown in the above embodiment, the adhesive holding groove 32a and the adhesive 33 filled in the adhesive holding groove 32a in the joiner 3 are both left and right of the opening of the concave groove 30 (see FIG. In the illustrated example, it is provided on the outer side of the water-stopping material holding groove 37a), and the back surface of the side end portion of the protruding corner member 2 is also bonded and fixed. In this case, it is possible to further reduce a possibility that a gap is generated between the outer wall material 4 and the protruding corner material 2.

いずれの実施例においても、出隅材２を取り付けるための出隅用下地材１を設置すれば、出隅材２と外壁材４とをシーリングレス工法で接合するためのジョイナ３，３も設置されるものであり、ジョイナ３の施工を別途行う必要がない。このために、建物の出隅部分の外壁工事の手間を削減することができる。特に図示例のようにシーリングレス工法のためのジョイナ３を出隅用下地材１に一体に設けたものでは、湿式シーリング工法の場合のような縦目地へのシーリング充填作業も必要としないために、出隅回りの工事を更に簡便化することができる。   In any of the embodiments, if the base material 1 for the projected corner for installing the projected corner material 2 is installed, the joiners 3 and 3 for joining the projected corner material 2 and the outer wall material 4 by the sealingless method are also installed. Therefore, it is not necessary to perform the construction of the joiner 3 separately. For this reason, the trouble of the outer wall construction of the projecting corner portion of the building can be reduced. Particularly, in the case where the joiner 3 for the sealing-less construction method is integrally provided in the base material 1 for the protruding corner as in the illustrated example, it is not necessary to fill the vertical joint as in the case of the wet sealing construction method. The construction around the corner can be further simplified.

なお、ジョイナ３の凹溝３０部分の背面は、図示例では出隅の柱８に接しているが、柱８から浮いていてもよい。つまり凹溝３０の深さが図示例のものよりも浅くてもよい。   In addition, although the back surface of the concave groove 30 portion of the joiner 3 is in contact with the column 8 at the protruding corner in the illustrated example, it may float from the column 8. That is, the depth of the concave groove 30 may be shallower than that of the illustrated example.

また、柱８が鉛直に設置されている場合、ジョイナ３の底板部３４をビスや釘等の固定具で建物躯体８に固定してもよい。もっとも、凹溝３０は上述の如く雨水排水部として用いる関係上、固定具にはボンデッドワッシャー等の止水ワッシャーを取り付けたり、固定具として止水機能付ビスを用いることが好ましい。   Moreover, when the pillar 8 is installed vertically, the bottom plate portion 34 of the joiner 3 may be fixed to the building frame 8 with a fixing tool such as a screw or a nail. However, since the groove 30 is used as a rainwater drainage portion as described above, it is preferable that a water stop washer such as a bonded washer is attached to the fixture, or a screw with a water stop function is used as the fixture.

上記の各実施例においては、シーリングレス工法用のジョイナ３を出隅用下地材１の両側に夫々一体に設けたものを示したが、湿式シーリング工法で施工される外壁の出隅については、外壁材４と出隅材２との間の縦目地に充填されるシーリング材の背後に配置するバックアップ材としてのジョイナを出隅用下地材１と一体に設けることで、出隅部分の工事の簡便化を図ることができる。   In each of the above embodiments, the sealer-less joiner 3 is integrally provided on both sides of the base material 1 for the projecting corner. However, for the projecting corner of the outer wall constructed by the wet sealing method, By installing a joiner as a back-up material to be placed behind the sealing material that fills the vertical joint between the outer wall material 4 and the protruding corner material 2 with the protruding corner base material 1, Simplification can be achieved.
