Raindrops will not directly pass through the plate unit, but will be divided into two parts on the wedge surface. One part will be scattered as small raindrops and continue to fall, and the other part will form a small-scale splash. At the same time, the wedge shape has good rigidity, and it is not easy to generate vibration noise under the impact of raindrops, reducing the impact intensity of rainwater;

[0181] 2) Using the through-groove element at the bottom of the panel unit, the panel unit and the facade are not completely closed, destroying the resonance cavity inside the panel unit, thereby weakening the intensity of the sound;

[0182] 3) The sound insulation unit is used to fill the interior of the plate unit to absorb sound and occupy the internal space of the plate unit, so that the air inside the plate unit cannot resonate with the metal, which greatly reduces the intensity of the sound, reduces the noise interference caused by the plate unit on rainy days, and improves living comfort;

[0183] 4) The through groove element at the bottom of the plate unit is waterproofed by using a waterproof unit, thereby improving the waterproof property.
