The base 54b part and the cover part 54a are integrally formed on the outer wall 505 near the corner part of the existing building. Since the body edge 502 extending in the vertical direction is disposed, and the base portion 54b is fixed to the outer wall 505 of the existing building through the body edge 502 together with the joining member 503, the cover portion 54a is the base. There is no displacement with respect to the part 54b, and the protruding corner member 504 can be reliably fixed to the outer wall 505 of the existing building. However, the protruding corner member 504 has high design, but has a complicated shape, and it is difficult to manufacture the metal plate by bending. (Patent Document 2)

As shown in FIG. 13, Patent Document 3 discloses a joint structure of an outer wall protruding corner that can improve designability.
The joint structure of the outer wall protruding corner portion of Patent Document 3 connects the side edges of a pair of fixed pieces 601 at a predetermined angle, and a pair of guide pieces 602 protrudes from this connecting portion to form a joining member 603. Each fixing piece 601 of the joining member 603 is disposed on the rear surface side of a plurality of outer wall members 604 that are formed and are installed at an angle equal to the predetermined angle with a gap therebetween, and a pair of the joining members 603. The guide piece 602 projects from the front surface of each outer wall member 604 through the gap, and the joint portion 602 projects from the outer wall member 604 to give an appearance accent to the joint portion. The design can be improved.
However, the joint structure of the outer wall protruding corner of Patent Document 3 is difficult to manufacture by bending a metal plate although it has high design, and in addition, between the side end of the outer wall material 604 and the guide piece 602. The sealant 605 was required. Furthermore, when the length of the joining member is insufficient in the vertical direction as in a two-story building, the plurality of joining members 603 are adjacent to each other so that the fixed piece 601 and the guide piece 602 are continuous. However, since the joint between the joining members may be conspicuous if it is used as it is, the joint 609 formed of a metal such as aluminum is used to cover the joint between the connecting members with the joint 609. In addition to making the joint inconspicuous, it is necessary to prevent the positions of the joining members 603 adjacent in the vertical direction from being shifted.

The joining state of the decorative member 21 and the fixing member 11B is joined by the same method as the joining state of the decorative member 21 and the fixing member 11A.

As shown in FIG. 6, the joining state of the decorative member 21 and the fixing member 11A of the first embodiment is that the engaging piece 22A is longer than the folded piece 222A, and the engaging piece 22A and the folded piece 222A are engaged. In the engagement space 223A formed by the end portion 221A, the engagement piece 22A and the folded piece 222A are substantially parallel. The distance TA3 between the engagement piece 22A and the folded piece 222A is the same as the thickness TA2 of the guide piece 12A.
Therefore, since the guide piece 12A of the fixing member is inserted into the engaging space 223A formed by the engaging piece 22A, the folded piece 222A, and the engaging end 221A of the decorative member without any gap, the decorative member 21 and the fixing member 11A are connected. The decorative member 21 and the fixing member 11 </ b> A are bonded without bonding or crimping for bonding.

As shown in FIG. 7, the joining state of the decorative member 21 and the fixing member 11A of the second embodiment is such that the interval TA1 between the engagement piece 22A and the folded piece 222A is larger than the thickness TA2 of the guide piece 12A. It is getting wider. However, since the decorative member and the fixing member are not fixed in this state, in the engagement space 224A of the portion where the decorative member 21 and the fixing member 11A overlap (cross section CC in FIG. 1), as shown in FIG. The tip of the folded piece 222A presses the guide piece 12A to join the decorative member 21 and the fixing member 11A.
On the other hand, the engagement space 223A of the decorative member 21 where the decorative member 21 and the fixing member 11A do not overlap, such as the upper end portion 45 of the extended corner member and the lower end portion 46 of the extended corner member, is illustrated in FIG. The interval TA1 between the engaging piece 22A and the folded piece 222A is wider than the thickness TA2 of the guide piece 12A.
