Water is realized.

  Further, as shown in FIG. 2, the second water stop portions 65a and 65b are configured by plate surfaces parallel to the back surfaces 1b and 2b, similarly to the first water stop portions 62a and 62b. 2b has a portion that abuts on the surface in the range of widths Wc and Wd. Thus, by ensuring the widths Wc and Wd, the sealing surfaces 13e and 13f having the widths Wc and Wd are formed, and reliable water stop can be achieved. A packing material made of rubber or resin is provided on the second water stop portions 65a and 65b, and a packing material is provided between the second water stop portions 65a and 65b and the back surfaces 1b and 2b of the outer wall materials 1 and 2. It may be configured to be interposed. That is, it is good also as a structure which can contact 2nd water stop part 65a * 65b via packing material with respect to each back surface 1b * 2b. In addition, it is also conceivable that the second water stop portions 65a and 65b are not in contact with the back surfaces 1b and 2b, and the sealing surfaces 13e and 13f are not formed.

  Further, as shown in FIG. 2, the first water stop portions 62a and 62b and the second water stop portions 65a and 65b are arranged to be separated from each other by the widths We and Wf. -In back surface 1b * 2b of 2, the site | part 1m * 2m which does not contact a water stop part is formed.

  Here, in FIG. 2, when the first water stop portions 62 a and 62 b and the second water stop portions 65 a and 65 b are continuously provided, the portions 1 m and 2 m that do not contact the water stop portions are formed. However, a series of sealing surfaces will be formed between the back surfaces 1b and 2b, and when a small gap is formed on this sealing surface, water penetrates by the so-called capillary phenomenon, It will pass the 2nd water stop part 65a * 65b.

  In this regard, according to the form of the first embodiment, the sealing surfaces are not formed in the portions 1m and 2m that do not contact the water stop portion, and the capillary phenomenon does not occur, so the first water stop portions 62a and 62b are formed. The water that has passed through the sealing surfaces 13a and 13b can be drained into the longitudinal groove portions 11a and 11b. In addition, since the seal surfaces 13c and 13d and the seal surfaces 13e and 13f are formed in a shifted position in the width direction of the outer wall materials 1 and 2, water can be stopped in two stages.

  Further, as shown in FIG. 2, the distance W1 from the fixed plate portion 61 to the first water stop portions 62a and 62b and the distance W2 to the second water stop portions 65a and 65b in the bonding accessory 6 are: Each is formed to be substantially the same as the depth width W3 of the ventilation space 15. That is, the depth dimension (distance W1, W2) in the indoor / outdoor direction of the portion between the outer wall materials 1, 2 and the waterproof sheet 5 in the joining accessory 6 is formed between the outer wall materials 1, 2 and the waterproof sheet 5. The depth dimension (distance W3) in the indoor / outdoor direction of the ventilation space 15 is set substantially the same. Thereby, in the construction method in which the ventilation space 15 is formed between the outer wall materials 1 and 2 and the waterproof sheet 5, it is possible to use the joining accessory 6 without using another spacer member or the like.

  Further, as shown in FIG. 2, the outer vertical plate parts 63 and 64 which are a part of the joining accessory 6 are respectively opposed to the vertical end surfaces 1 a and 2 a of the outer wall materials 1 and 2 through packing materials 73 and 74. You are going to be able to do it. As a result, if a situation occurs in which the outer wall materials 1 and 2 are laterally displaced so as to approach the outer vertical plate portions 63 and 64, the outer vertical wall portions 63 and 64 cause the outer wall materials 1 and 2 to move. It is possible to regulate the deviation. This effect is due to, for example, a construction method in which the lateral displacement of the outer wall materials 1 and 2 is not prevented, for example, when the fixing bracket for fixing the outer wall materials 1 and 2 to the housing side does not have the function of preventing lateral displacement. Is particularly effective.

  Further, as shown in FIG. 2, by using the joining accessory 6 of the first embodiment, the vertical end surfaces 1 a and 2 a of the outer wall materials 1 and 2 for constituting the protruding corner portion 20 are vertical without step processing. It can be an end face. For this reason, for example, when adjustment of the width dimension of the outer wall material 1 is necessary, if the outer wall material 1 is only cut at the construction site, the end face of the cut portion is subjected to joint trimming or the like. Construction can be completed without requiring special step processing, and excellent workability can be realized.

  In the second embodiment, as shown in FIG. 3, the outer vertical plate portion for configuring the appearance of the joining accessory 6 </ b> A having an arc cross section recessed at the protruding corner portion 20 at the distal end portion of the vertical plate portion 62. 66, and a configuration in which packing materials 67 and 68 are interposed between the outer vertical plate portion 66 and the vertical end surfaces 1a and 2a, and the other configurations are the same as those of the first embodiment.

  In this way, by using the outer vertical plate portion 66 having an arc cross section as shown in FIG. 3, it is possible to configure the appearance design at the protruding corner portion 20 with the curved surface of the outer vertical plate portion 66. Become. In addition to the configuration shown in FIG. 3, a configuration in which an outer vertical plate portion having an arc cross-section swelled at the protruding corner portion 20 is provided, or a separate decorative material is attached to the outer vertical plate portion 66 and the decorative material is used.
