The joining accessory 6 is composed of a long member, fastened to the pillar 4 with a screw 7, and a part thereof is inserted into a space K formed on the back side of the back solid parts 11, 12. It is paid in.

  The joining accessory 6 fulfills the positioning function of the outer wall material 1 by abutting the back solid parts 11 and 12 of the outer wall material 1 from the left and right directions, and contacts a part of the back side of the outer wall material 1. Thus, it functions to prevent water from entering the back side of the outer wall material 1 from the joint S. In order to exhibit the water stop function more effectively, it is preferable to provide the joining accessory 6 with a water stop material 8 that is in close contact with the back solid parts 11 and 12 from the back side.

  As shown in FIG. 3A, a back solid part 11 is formed at the right end of the left outer wall material 1. The back solid part 11 has the protrusion part 11a which comprises an outer wall surface, and the notch part 11b of the back side of the protrusion part 11a. In the cutout portion 11b, a back real back surface 11x constituting the back side surface of the protruding portion 11a and a back prospect surface 11y substantially orthogonal to the back real back surface 11x are formed. The prospective back surface 11y is continuous with the back surface 1b while being substantially orthogonal to the back surface 1b of the outer wall material 1. The same applies to the back solid portion 12 of the right outer wall material 1.

  As shown in FIG. 3 (B), in a state where the back real parts 11 and 12 face each other in the left-right direction, the substantially U-shape is opened toward the back side by the notches 11b and 12b. A space K is formed. This space K constitutes a vertical groove space extending in the vertical direction.

  In addition, since the space K is formed in this way, as shown in FIG. 2 and FIG. 3 (B), in the state in which the back solid parts 11 and 12 are abutted against the bonding accessory 6, the bonding is performed in the space K. A part of the utility item 6 is stored.
