In the structure shown in FIG. 5, since the upper outer wall material 2 is pressed against the base material 3 by the inclined pressing surface 21a, no mounting bracket or the like is required. However, since the nailing position of the nail 23 in the consolidation receiving portion 21 is left to the discretion of the on-site installer, the nailing position of the nail 23 varies greatly, and the nail 23 is driven into the vicinity of the tip of the consolidation receiving portion 21. If this occurs, cracks may occur. Further, the waterproof seal 24 is provided on the inner side of the joint than the nail 23, and its function cannot be effectively exhibited.

[0008] The present invention has been made in view of such circumstances, and the purpose of the present invention is that despite the fact that the nailing position for attaching to the base material is provided in the confluence receiving portion. Another object of the present invention is to provide a structure of a jointed joint portion of an outer wall material which can prevent occurrence of cracks such as cracks in the joint receiving portion and is excellent in waterproofness.

[0009]

According to the present invention, there is provided an outer wall material joining / joining structure comprising: a first outer wall material having a joining receiving portion into which a nail for attaching to a base material is driven; Joint joining with a second outer wall material having a consolidation pressing portion to be formed, and having a slope receiving surface pressed by an inclined pressing surface at the tip of the consolidation receiving portion at a root portion of the consolidation pressing portion. The structure of the portion, wherein a waterproof tape is attached to the nailing position of the consolidation receiving portion, between the consolidation receiving portion and the consolidation presser, at the root side of the consolidation receiving portion, A waterproof seal is provided to close the gap between the consolidation receiving portion and the consolidation pressing portion.

[0010]

According to the joint structure of the outer wall material of the present invention, since the waterproof tape is attached to the nailing position of the joint receiving portion, the occurrence of cracks or the like due to the variation in the nailing position is prevented. Further, the structure of the joint of the outer wall material of the present invention has a double waterproof mechanism of the waterproof seal and the waterproof tape, so that the waterproof seal blocking the entrance of the joint is pierced. However, it prevents the waterproof tape from leaking from the nail hole to the base material side.
