Curtain wall projects are an important part of outdoor decoration projects. In exterior finishing projects, one of the more difficult parts to deal with is the closing of the exterior facings at the expansion joints. Most of the existing aluminum plate decorative surfaces at the expansion joints are closed by connecting the aluminum plate facings with the aluminum plates and then gluing them. However, with this treatment method, after a period of time, gaps are easily formed between the aluminum plate facings. During the rainy season or when the curtain wall facings are cleaned, water stains will flow into the inside, affecting the interior decoration effect. At the same time, the erosion of rainwater will reduce the service life of the aluminum plate curtain wall. Utility Model Content
