FIG. 1A is a schematic perspective view showing a lateral end side of a lower outer wall panel 1 and an upper outer wall panel 1 used in the waterproof structure of this embodiment, and FIG. 1B shows an upper outer wall panel 1. It is the schematic perspective view which turned upside down and showed the lower end part facing up. For example, a sandwich panel is used as the outer wall panel 1. This sandwich panel has an outer steel plate 1a on the front side, a core 1b, and an inner steel plate 1c on the back side. The core material 1b is made of rock wool, glass wool or the like.
　上記外壁パネル１の上端には、凸部１１が形成されるとともに当該凸部１１よりも下側（外壁パネル１の上部側）に横目地となる目地部位１２が形成されている。また、上記凸部１１と上記目地部位１２との間には、横方向に長く凹部１３が形成されている。さらに、上記外壁パネル１の屋内側の上部位置には横方向に長く段部１４が形成されている。各外壁パネル１は、上記凹部１３の箇所からねじ込まれたドリルビス等によって図示しない胴縁（リップ溝型鋼等）に固定される。 A convex portion 11 is formed at the upper end of the outer wall panel 1 and a joint portion 12 serving as a horizontal joint is formed below the convex portion 11 (upper side of the outer wall panel 1). Further, a concave portion 13 is formed between the convex portion 11 and the joint portion 12 in the lateral direction. Further, a stepped portion 14 is formed in the upper position on the indoor side of the outer wall panel 1 in the lateral direction. Each outer wall panel 1 is fixed to a trunk edge (lip groove type steel or the like) (not shown) by a drill screw or the like screwed from the concave portion 13.
　また、上記外壁パネル１の下端の屋内側には下方に突出する突出部１５が横方向に長く形成されており、屋外側には下方に突出する垂れ部１６が横方向に長く形成されている。上記突出部１５と上記垂れ部１６との間には、上記凸部１１が嵌合する凹部が形成されている。 Further, a projecting portion 15 projecting downward is formed in the lateral direction on the indoor side at the lower end of the outer wall panel 1, and a hanging portion 16 projecting downward is formed in the lateral direction on the outdoor side. . A concave portion into which the convex portion 11 is fitted is formed between the protruding portion 15 and the hanging portion 16.
　図２Ａおよび図２Ｂに示すように、上側の外壁パネル１における上記突出部１５と上記垂れ部１６との間の凹部には、耐火材である例えばセラミックウール２とテープ状の粘着面付きのシール材３が、例えば、施工現場において貼り付けられる。上記シール材３は上記凹部の屋外側であって、上記垂れ部１６を形成する上記外側鋼板１ａにおける上記凹部内端部上に貼られる。なお、上記セラミックウール２、上記シール材３、後述するシール材４，５、６等は、上側の外壁パネル１と下側の外壁パネル１とを嵌合させる前に設けられる。 As shown in FIG. 2A and FIG. 2B, the recess between the protruding portion 15 and the drooping portion 16 in the upper outer wall panel 1 has a seal with a fireproof material such as ceramic wool 2 and a tape-like adhesive surface. The material 3 is stuck on the construction site, for example. The sealing material 3 is on the outdoor side of the recess, and is stuck on the inner end of the recess in the outer steel plate 1 a that forms the drooping portion 16. The ceramic wool 2, the sealing material 3, sealing materials 4, 5, and 6 to be described later are provided before the upper outer wall panel 1 and the lower outer wall panel 1 are fitted together.
　図３に示すように、上側の外壁パネル１における上記突出部１５と上記垂れ部１６との間の凹部の横側端面の近傍には、上記セラミックウール２および上記シール材３に交差するように、テープ状の粘着面付きのシール材（別のシール材）４が貼り付けられる。また、上記シール材４は、上記凹部の屋外側の立面（上記垂れ部１６の裏面）を形成する外側鋼板１ａから、上記垂れ部１６の下端を形成する外側鋼板１ａにかけても貼り付けられ、さらに、上記突出部１５にも貼り付けられる。上記シール材４の貼り付け作業は、例えば、施工現場において行われる。上記シール材４としては、例えば、厚さが８～１５ｍｍで幅が１０～１５ｍｍのものが用いられる。上記シール材４としては、用いる外壁パネル次第で様々な厚さや幅のものが用いられることになる。図では、便宜上、上記シール材４の厚さを薄くして描いている。また、下側の外壁パネル１および上側の外壁パネル１の嵌合は、図の状態よりも、上下の外壁パネル１、１がもう少し接近して完了となる。このとき、上記シール材４と後述のシール材５とが、上下の外壁パネル１、１の凸部１１と凹部との嵌合箇所において互いに圧接することになる。なお、上記垂れ部１６によって上記目地部位１２の全部が塞がれることはない。他の図においても同様である。 As shown in FIG. 3, the ceramic wool 2 and the sealing material 3 are crossed in the vicinity of the lateral end face of the recess between the protruding portion 15 and the hanging portion 16 in the upper outer wall panel 1. Then, a sealing material 4 (another sealing material) 4 with a tape-like adhesive surface is attached. Further, the sealing material 4 is also pasted from the outer steel plate 1a that forms the outdoor surface of the concave portion (the back surface of the sagging portion 16) to the outer steel plate 1a that forms the lower end of the sagging portion 16, Furthermore, it is affixed also to the said protrusion part 15. FIG. The pasting work of the sealing material 4 is performed at a construction site, for example. As the sealing material 4, for example, a material having a thickness of 8 to 15 mm and a width of 10 to 15 mm is used. As the sealing material 4, those having various thicknesses and widths are used depending on the outer wall panel to be used. In the drawing, for convenience, the sealing material 4 is drawn with a small thickness. Further, the fitting of the lower outer wall panel 1 and the upper outer wall panel 1 is completed when the upper and lower outer wall panels 1 and 1 are slightly closer than in the state shown in the figure. At this time, the sealing material 4 and a sealing material 5 described later are brought into pressure contact with each other at a fitting portion between the convex portion 11 and the concave portion of the upper and lower outer wall panels 1, 1. Note that the joint portion 12 is not completely blocked by the drooping portion 16. The same applies to the other drawings.
　上記下側の外壁パネル１の横側端面の近傍の屋外面には、テープ状の粘着面付きのシール材５が、上記目地部位１２の上側となる箇所から当該目地部位１２内を通り、下方向に設けられる。上記シール材５としても、例えば、厚さが８～１５ｍｍで幅が１０～１５のものが用いられるが、用いる外壁パネル次第で厚さや幅は異なることになる。また、図では、便宜上、上記シール材５の厚さを薄くして描いている。上記シール材５における上記目地部位１２の下側に位置する部分である一端側については、上記目地部位１２の下縁から例えば５～１０ｃｍ程度の長さで設けられる。この長さは、用いる外壁パネル次第で異なることになる。また、この一端側のシール材部分は、後述の纏めが行われるまでの間、剥離紙を付けたままとしてもよいし、剥離紙を剥がして粘着面を屋外面に貼り付けておいてもよい。上記シール材５の取り付け作業は、例えば、施工現場において行われる。また、上記シール材５の他端側は、上記上端の凸部１１を越えて屋内面（例えば、上記段部１４の下部）へ延長されている。 On the outdoor surface in the vicinity of the lateral end face of the lower outer wall panel 1, a tape-like adhesive material 5 with an adhesive surface passes through the joint portion 12 from a location above the joint portion 12, Provided in the direction. As the sealing material 5, for example, a material having a thickness of 8 to 15 mm and a width of 10 to 15 is used. However, the thickness and the width are different depending on the outer wall panel to be used. In the drawing, the thickness of the sealing material 5 is reduced for the sake of convenience. One end side, which is a portion located below the joint part 12 in the sealing material 5, is provided with a length of, for example, about 5 to 10 cm from the lower edge of the joint part 12. This length will vary depending on the outer wall panel used. In addition, the sealing material portion on one end side may be left with release paper until the below-described summarization is performed, or the release paper may be peeled off and the adhesive surface may be attached to the outdoor surface. . The installation work of the sealing material 5 is performed at a construction site, for example. Further, the other end side of the seal material 5 extends to the indoor surface (for example, the lower portion of the step portion 14) beyond the convex portion 11 at the upper end.
　上記下側の外壁パネル１の横側端面の近傍の屋外面であって上記凹部１３の箇所にもテープ状の粘着面付きのシール材６を貼り付ける。図では、厚さが薄いシール材６を２枚重ねているが、これに限らず、厚さが厚いシール材を１枚用いるようにしてもよい。また、上記シール材６の貼り付け作業は、例えば、施工現場において行われる。 The sealing material 6 with a tape-like adhesive surface is attached to the outdoor surface in the vicinity of the lateral end surface of the lower outer wall panel 1 and also to the recess 13. In the drawing, two thin sealing materials 6 are stacked, but the present invention is not limited to this, and one thick sealing material may be used. Moreover, the sticking operation | work of the said sealing material 6 is performed in a construction site, for example.
　そして、図４に示すように、施工現場において、上記シール材５の下部側となる一端側を纏めて上記目地部位１２内に収める。このシール材の纏め作業は、下側の外壁パネル１の上側に上側の外壁パネル１を嵌合させた後に行われる。また、この纏め方としては、上記シール材５の下部側を巻いて丸めたり、折り畳んだりする方法がある。また、この纏められた状態では、シール材間には隙間が生じないようにし、また、上記シール材５が上記目地部位１２の屋外端を越えて盛り上がるようにするのが望ましい。このように盛り上がっていると、後述する目地カバー７で押され、さらに隙間が生じにくくなる。なお、上記目地部位１２内の上記纏められたシール材５の横位置に、定型または不定形のシール材１２ａを設けてもよい。 Then, as shown in FIG. 4, at the construction site, one end side which is the lower side of the sealing material 5 is put together in the joint portion 12. The sealing work is performed after the upper outer wall panel 1 is fitted to the upper side of the lower outer wall panel 1. Further, as a way of grouping, there is a method in which the lower side of the sealing material 5 is wound and rounded or folded. Further, in this gathered state, it is desirable that no gap is generated between the sealing materials, and that the sealing material 5 rises beyond the outdoor end of the joint portion 12. If it rises in this way, it will be pushed by the joint cover 7 mentioned later, and it will become difficult to produce a clearance gap further. In addition, you may provide the sealing material 12a of a fixed form or an indeterminate form in the horizontal position of the said collected sealing material 5 in the said joint part 12. FIG.
　次に、図５に示すように、施工現場において、目地カバー７を配置する。なお、図では、上記外壁パネル１と左右に隣り合う外壁パネルの図示を省略している。上記目地カバー７は、左右に隣り合う外壁パネル間に形成される縦目地内に入り込む矩形状の凸部を有しており、この凸部の左右側に板状部が曲げ形成されたハット形状を有する。なお、上記縦目地内には、上記目地カバー７の取り付けに先だって、耐火材として例えばセラミックウール７１を入れ込んでおく。また、上記目地カバー７の上記板状部の裏面側には、上記矩形状の凸部を両側から挟み込むように、テープ状の粘着面付きのシール材７２を貼り付けておく。上記シール材７２としては、例えば、厚さが５ｍｍで幅が２０ｍｍのものが用いられる。 Next, as shown in FIG. 5, the joint cover 7 is arranged at the construction site. In the drawing, the outer wall panel 1 and the outer wall panel adjacent to the left and right are not shown. The joint cover 7 has a rectangular convex portion that enters a vertical joint formed between left and right outer wall panels, and a hat shape in which plate-like portions are bent and formed on the left and right sides of the convex portion. Have In addition, prior to attachment of the joint cover 7, for example, ceramic wool 71 is put in the vertical joint as a refractory material. Further, a sealing material 72 with a tape-like adhesive surface is attached to the back side of the plate-like portion of the joint cover 7 so as to sandwich the rectangular convex portion from both sides. As the sealing material 72, for example, a material having a thickness of 5 mm and a width of 20 mm is used.
　上記の構成であれば、シール材５の下部側となる一端側が纏められて上記目地部位１２内に収められるので、専用の定型シール材を用いるような場合やカッターで切り取られたブロック状のシール材を用いるような場合の不完全なシール状態を生じ難くすることができ、上記目地部位(横目地)１２から上記縦目地への雨水浸入の防止力を高めることができる。また、シール材５として汎用のテープ状のシール材を用いると、この場合には専用の定型シール材を用いる場合に比べて低コスト化も図れる。なお、粘着面付きのシール材を用いることに限定されず、現場でシール材に粘着剤を塗布するようにしてもよい。 If it is said structure, since the one end side used as the lower part side of the sealing material 5 is collected and it accommodates in the said joint part 12, the block-shaped seal | sticker cut off when using a special fixed sealing material or a cutter An incomplete sealing state in the case of using a material can be made difficult to occur, and the ability to prevent rainwater from entering from the joint portion (horizontal joint) 12 to the vertical joint can be enhanced. In addition, when a general-purpose tape-shaped sealing material is used as the sealing material 5, the cost can be reduced as compared with the case where a dedicated fixed sealing material is used. In addition, it is not limited to using the sealing material with an adhesive surface, You may make it apply | coat an adhesive to a sealing material on the spot.
　上記シール材５の他端側が上記上端の凸部１１を越えて屋内面へ延長されていると、上記屋内面での防水性を高めることができる。 When the other end side of the sealing material 5 extends beyond the convex portion 11 at the upper end to the indoor surface, the waterproof property on the indoor surface can be enhanced.
　上記シール材５の他端側が上側の外壁パネル１の屋内側の突出部１５と上記屋内面との間で挟まれるようにしてあると、上側の外壁パネル１の屋内側の突出部１５と上記屋内面との間の防水性を向上させることができる。 When the other end side of the sealing material 5 is sandwiched between the indoor-side protruding portion 15 of the upper outer wall panel 1 and the indoor surface, the indoor-side protruding portion 15 of the upper outer wall panel 1 and the above-mentioned The waterproof property between indoor surfaces can be improved.
　上側に位置する外壁パネル１の下端側であってその横側端面の近傍にシール材４が設けられていると、外壁パネル１の上端と上側に位置する外壁パネル１の下端との間の防水性を向上させることができる。 When the sealing material 4 is provided on the lower end side of the outer wall panel 1 positioned on the upper side and in the vicinity of the lateral end face, the waterproofing between the upper end of the outer wall panel 1 and the lower end of the outer wall panel 1 positioned on the upper side is provided. Can be improved.
