Description of the Related Art Conventionally, when constructing an outer wall, it has been widely practiced to connect an inorganic wall plate formed in a unit size in up, down, left and right directions to form a large-area outer wall. As a means for connecting the wall plates, generally, as shown in FIG. 3, they are connected in the vertical direction via a joining step A, for example, a gouge joint or a real joint, and are butted in the left and right direction. A sealing material D is filled on the front surface side with a backup material C interposed between the wall plates B and B end faces, and connection is performed while waterproofing. Further, as shown in FIG. 4, not only in the up-down direction but also in the left-right direction, connection is made via joining steps A to A, for example, a gouge joint or a real joint, and the joint joint is filled with a sealing agent D. It is connected while performing waterproofing.

する部分から壁板裏面へと流入していく問題があった。In the case where the connection is made in the vertical and horizontal directions through the joining steps as described above, in the waterproof structure shown in FIG. When a break in the sealing agent occurs due to aging at some point in the longitudinal joint E, rainwater enters from there and penetrates and flows down along the joint, and from a portion where the horizontal joint F and the vertical joint E intersect. There was a problem of flowing into the back of the wallboard.

However, waterproofing at four corners B 'of the wall plate B is not sufficient. There was a disadvantage that it was likely to be complete. That is, each wall plate B is butt joints between the protruding engagement Godan portion A 1 and the recessed engaging Godan unit A 2 butt joint E of the engaged gradually but wallboard surface by and engaging stepped portions of the inner Since F is located in a staggered manner, a pinhole-shaped through-hole is formed at the intersection G, G, which penetrates directly to the back surface of the wall plate, and when the sealing agent deteriorates over time, rainwater flows to the back surface of the wall plate. There was invasion.
