[0029] In Fig. 11, it shows the rain finishing structure of the upper surface K2 part of the opening K. Even if rainwater W penetrates from the stop edge X or the stop edge corner cap H, the penetration into the wall base α is prevented by the opening corner packing P and the discard plate T formed on the left and right, and the rainwater is drained to the outside from the notch X1 part formed in the stop edge X through the gap B.
[0030] In Fig. 12, it shows the rain finishing structure of the left and right side surface K1 parts of the opening K. Even if rainwater W penetrates from the fixing surface 8 of the joint plate M2 or the stop edge corner cap H, the penetration into the wall base α is prevented by the opening corner packing P and the sealing S formed on the left and right, and the rainwater is discharged to the surface side of the dry wall material A.
[0031] Fig. 13 is (a), (b) is the opening K Lower surfaceIt shows the rainproof structure of the K3 part. Figure (a) shows the case where no notch 12b (see Fig. 16) is formed in the decorative cap M3. When the external pressure increases due to wind and rain, the internal pressure inside the decorative edge M1 decreases, and due to this pressure difference, rainwater is likely to penetrate inside. In contrast, Figure (b) shows the case where a plurality of notches 12b (see Fig. 16) are formed in the decorative cap M3 of the decorative edge M1. Even when the external pressure increases due to wind and rain, the internal pressure inside the decorative edge M1 also increases, so it becomes difficult for rainwater to penetrate inside.
[0032] Fig. 14, (a) and (b) are for the opening K Lower surface It shows the rainproof structure of the K3 part. Figure (a) shows the case where no notch 12b (see Fig. 16) is formed in the decorative cap M3. When the external pressure increases due to wind and rain, the internal pressure inside the decorative edge M1 decreases, and due to this pressure difference, rainwater is likely to penetrate inside. In contrast, Figure (b) shows the case where a dry wall material A with a plurality of grooves 16a formed on the surface of the metal surface material 16 as shown in Fig. 15 is constructed. Due to the grooves 16a of the dry wall material A, even when the external pressure increases due to wind and rain, the internal pressure inside the decorative edge M1 also increases, so it becomes difficult for rainwater to penetrate inside.
[0033] Also, when constructing the dry wall material A as shown in Figs. 8 and 15, as shown in Fig. 17, a sealing S is applied between the fixing part 21 of the fitting part of the dry wall material A and the fixing surface 8 of the joint board M2 to strengthen the waterproof performance.
[0034] The decorative cap M3 shown in Fig. 16 forms notches 12b obtained by cutting off the step 12a part at regular intervals. These notches 12b make the internal pressure inside the space of the decorative edge M1 formed on the lower surface K3 part after construction the same as the external pressure, and prevent rainwater from penetrating inside. 15 inside the same as the external pressure, and prevent rainwater from penetrating inside.
