 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings. 1 to 3 show an embodiment of the present invention. A plate 7 is fixed to the inner surface of the lower frame 2 of the upper outer wall panel 1a, and a hole communicating with the plate 7 and the lower frame 2 is provided. Further, a plate 8 is fixed to the inner surface side of the upper frame 3 of the lower outer wall panel 1b, and a screw hole is provided in this plate 8, and the screw hole of the plate 8 is a hole provided in the upper frame 3. Is in communication with. Then, in the present invention, the bolt 4 is inserted from the hole of the plate 7 of the upper outer wall panel 1a, the hole of the lower frame 2 of the upper outer wall panel 1a, and the hole of the upper frame 3 of the lower outer wall panel 1b. The upper and lower outer wall panels 1a and 1b are joined vertically by being inserted into the screw holes of the plate 8 in this case. In this case, the lower frame 2 of the upper outer wall panel 1a and the lower outer wall panel 1a are joined together. Watertightness is obtained by interposing a waterproof sheet 5 on the outdoor side of the bolt 4 and on the indoor side of the bolt 4 between the upper frame 3 of 1b, and tightening the bolts 4 to bond the waterproof sheet 5 from above and below. Is being secured. Here, the waterproof sheet 5a on the outdoor side of the waterproof sheet 5 is attached along the outer half of the upper surface of the upper frame 3 and the outer surface side of the outdoor side piece 3a, and the lower outer wall panel 1 The face plate 9 of b is attached via the vertical portion 10 of the waterproof sheet 5a so that water does not enter from between the face plate 9 and the upper frame 3. Further, among the waterproof sheets 5 interposed between the lower frame 2 of the upper outer wall panel 1a and the upper frame 3 of the lower outer wall panel 1b on the outdoor side of the bolt 4 and on the indoor side of the bolt 4 respectively. The indoor waterproof sheet 5b is attached to the upper half of the upper frame 3 on the indoor half in advance, or is attached to the lower half of the lower frame 2 on the indoor half. Further, another waterproof sheet 5c is interposed between the outdoor side piece 2a of the lower frame 2 of the upper outer wall panel 1a and the face plate 9 so that water may enter from between the face plate 9 and the lower frame 2. I try not to. Then, the caulking material 11 is filled on the outdoor side of the joint between the upper and lower outer wall panels 1a and 1b. By doing so, even if rainwater intrudes from the joints between the upper and lower outer wall panels 1a, 1b, the caulking material 11 first waterproofs the water. However, even if the waterproofing by the caulking material 11 is broken, Between the upper frame 3 and the lower frame 2, the waterproof sheet 5a and the waterproof sheet 5b are provided on both sides of the joint by tightening the bolts 4, so that waterproofing can be carried out in two stages and rainwater can be surely prevented from entering. Therefore, the outer surface of the waterproofed portion as described above does not have to be provided with the toilet drainer 12 as in the conventional case. However, FIG. 3 shows an example in which the upper outer wall panel 1a is the outer wall panel on the second floor and the lower outer wall panel 1b is an intermediate panel which is a curtain panel. In the waterproof treatment between the outer wall panel 1c on the first floor and the lower outer wall panel 1b which is the middle panel, the waterproof treatment is performed between the outer wall panel 1c on the first floor and the lower outer wall panel 1b which is the middle panel as in the conventional case. A coking agent 16 is filled between the water draining plate 15 and the lower outer wall panel 1b which is an intermediate panel with the water draining plate 15 interposed, and the cosmetic water draining plate 12 is further covered. As a result, the outer wall of the building has only one toilet draining plate 12 in the approximately middle portion between the upper and lower floors, which improves the appearance.
