Next, the flow of rainwater will be described with reference to FIG. In general, in a box-curved panel formed by bending a plate, in order to prevent rainwater from entering the inside, the contact portion between the bent plates is sealed by welding or a filler to stop water. There is a need. In this case, in a metal resin composite plate such as an aluminum resin composite plate, it is necessary to seal instead of welding in order to prevent the resin from melting by welding. However, since the metal resin composite plate is deformed by the force from the skeleton, the force due to the thermal deformation of the metal resin composite plate, and the external force such as wind force, the distance between the bent plates is constantly changed, and the sealing may be broken. is there. There is also the possibility of breakage due to deterioration of the sealing. On the other hand, if the corner piece is used for reinforcement as described above, the sealing can be brought into close contact with the box-curved panel 110 to improve the filling degree, thereby reducing the possibility of breakage. However, if the sealing breaks, it is not possible to completely prevent rainwater from entering the inside because there is no backup.

Hereinafter, it is assumed that the sealing material and the corner piece 116 provided at the connecting portion between the upper bent plate 111 and the left bent plate 113 are broken and rainwater has infiltrated. Rainwater that has entered from the connection portion between the upper bent plate 111 and the left bent plate 113 penetrates to the left drainage channel 163 via the upper drainage channel 161. Further, rainwater falls vertically downward in the left drainage channel 163 and reaches the lower drainage channel 164. Here, since the upper drainage channel 161 and the left drainage channel 163 and the lower drainage channel 164 are stopped by the first seal portion 170 and the seal member 171, the upper drainage channel 161 and the left drainage channel 163 and the lower Rainwater does not seep out from the side drainage channel 164. Then, rainwater is discharged to the outside from the drainage port 180 provided in the lower drainage channel 164. Similarly, rainwater infiltrated from the connection portion between the upper bent plate 111 and the right bent plate 112, rainwater infiltrated from the connecting portion between the right bent plate 112 and the lower bent plate 114, and the left bent plate. Rainwater that has entered from the connection portion between the 113 and the lower bending plate 114 is also discharged to the outside from the drain port 180.

Further, even if rainwater invades the inside of the box-curved panel 110 from the joint between the bent plates, the rainwater is discharged to the outside from the drain port 180 via the drainage channel 161-164. Further, since the drainage channel 161-164 is stopped by the first seal portion 170 and the seal member 171 so that rainwater reaches the drainage port 180 without seeping out from the drainage channel 161-164. As a result, the water blocking performance of the panel unit 100 is improved, and rainwater that has entered from the joint between the bent plates does not reach the skeleton.
