In this case, the width b of the protrusions 12a and 12b of the molding material 12 is set smaller than the width B of the recess 10a of the wall panel 1 (b <B). It is easily fitted into recess 10a of panel 1A. Further, as described above, since the height h of the convex portions 12a and 12b of the molding material 12 is set smaller than the depth d of the concave portion 10a of the wall panel 1 (h <d), as shown in FIG. When the convex portion 12b of the molding material 12 is fitted into the concave portion 10a of the wall panel 1A, a gap is formed in the concave portion 10a, and the thickness t of the water-stopping material 11 filled in the gap is as described above. Is larger (t> Δh) than the height dimension Δh (see FIG. 4), the water-stopping material 11 is compressed by (t−Δh) in the gap.
[0029]
When the molding material 12 is set on the upper end surface of the lower wall panel 1A, as shown in FIG. 3, the upper wall panel 1B is moved downward so that the recess 10a is formed above the molding material 12. As shown in FIG. 4, the upper wall panel 1B is pushed down until the lower end joint surface thereof comes into contact with the joints 12c, 12d of the molding material 12, while being fitted in the convex portion 12a and maintaining the state. Then, as shown in FIG. 4, the upper wall panel 1B is stacked on and joined to the lower wall panel 1A by the molding material 12, and the joint between the upper and lower wall panels 1A and 1B is provided with an aluminum molding material. 12 joints 12c and 12d are interposed, and a projection 12e formed integrally with the end of the joint 12c on the bathroom side (front side) of the molding material 12 is between the joining end faces of the upper and lower wall panels 1A and 1B. Is covered from the inside (the bathroom side). Further, the water-stopping material 11 filled in the gap formed in the concave portion 10a of the upper wall panel 1B is also compressed by a predetermined amount (t-Δh) in the same manner as described above. The gap between the concave portions 10a of the upper and lower wall panels 1A, 1B is filled over the entire length to achieve an intended water stopping function.
