The existing building external wall decoration plate needs to be fixed with a plurality of vertical keels and horizontal keels on the wall surface to form a keel frame before installation, and then all the decoration plates are installed on the keel frame, and then are sequentially spliced into a complete wall surface.
[0003] However, due to the splicing process, a gap exists between the adjacent two decoration plates, which leads to water seepage at the gap between the adjacent two decoration plates in rainy days, which is easy to cause the wall body to be damp, and even causes the wall body to be damaged. In order to solve this problem, the existing decoration plate is filled with waterproof glue or foam glue at the gap between the adjacent two decoration plates after splicing, which can effectively prevent the occurrence of water seepage.
[0004] However, when the decoration plate is used for the building external facade, the waterproof glue or foam glue at the gap of the decoration plate will be affected by environmental factors, such as ultraviolet radiation, temperature change and humidity change, which will accelerate the aging or cracking of the waterproof glue or foam glue, thereby reducing or even completely losing the waterproof effect, which leads to the risk of the wall body being damp.
