  In the fixed piece portion 62a, a longitudinal piece portion 62b extending toward the back surface 21a of the outer wall material 21 is formed at an end portion on the side end 22 side of the outer wall material 21. The end portion of the vertical piece portion 62b is the back surface 21a. Abut.

  Further, in the vertical piece portion 62b, a vertical piece portion 62c extending from the end opposite to the fixed piece portion 62a toward the side end portion 22 of the outer wall material 21 and facing the back surface 21a of the outer wall material 21 is formed. Ru.

  And in the vertical piece part 62c, the engagement piece part 62d extended toward an outdoor side is formed in the edge part on the opposite side to the vertical piece part 62b. The engagement piece 62 d faces the prospective surface 23 d (surface in the depth direction) of the backing unit 23 formed on the side end 22 of the outer wall material 21 and abuts on the prospective surface 23 d to make the outer wall material It functions to prevent lateral displacement in the direction of the arrow X2 axis of 21.

  Assuming that the vertical frame 2 is inclined during the earthquake and the outer wall material 21 is displaced from the vertical frame 2 when the engaging piece 62 d does not exist, the shaking of the earthquake is suppressed and the vertical frame 2 is restored to the upright state Even if, the shift | offset | difference of the vertical frame 2 and the outer wall material 21 will remain. The presence of the engagement piece portion 62 d makes it possible to return the outer wall material 21 to the original state along with the return of the vertical frame 2.

  Further, in the fixed piece portion 62a, a longitudinal piece portion 62f extending toward the back surface 21a of the outer wall material 21 is formed on the side far from the side end 22 of the outer wall material 21.

  In addition, the fixed piece portion 62 a, the vertical piece portions 62 b and 62 f, and a part of the vertical piece portion 62 c of the lateral deviation prevention metal fitting 62 are accommodated inside the vertical groove portion 52 g of the projecting corner joint member 50. As a result, as shown in FIG. 1, it is possible to arrange the fixing fitting 41 and the lateral deviation preventing fitting 62 both arranged at the upper edge of the outer wall material 21 side by side in the lateral direction.

The present invention can be implemented as described above.
That is, as shown in FIGS. 4 (A) and 4 (B), the structure of the projected corner portion 1 of the outer wall formed by joining the side end portions 12 and 21 of the outer wall members 11 and 21 The backing portions 13 and 23 are respectively formed on the side end portions 12 and 21 of 21. The backing portions 13 and 23 are expected surface portions 13d, which constitute a vertical surface in the thickness direction of the outer wall material in plan view. And 23d and back surfaces 13e and 23e that form vertical planes orthogonal to the prospective surfaces 13d and 23d in plan view, and the width dimension We of the back surfaces 13e and 23e is the width dimension Wd of the prospective surfaces 13d and 23d The side end face 12m of the side end 12 of one outer wall material 11 is smaller than the other, and is disposed to face the back surface 23e of the other outer wall material 21. A corner gap 53 is formed between the portions 23e, and the structure of the protruding corner portion of the outer wall To.

  Thus, when an earthquake occurs, the prospective surface portion 13d of one outer wall material 11 abuts on the back surface 21a of the other outer wall material 21. Therefore, the side end surface 12m of the side end 12 of one outer wall material 11 abuts on the outer wall material 21 In the case of the side end 12 having a thin wall thickness, the occurrence of damage can be prevented.
