Abstract
Description

[0002] With the development of the modern construction industry, metal curtain walls have been widely used in the decoration of building exterior walls in my country. Traditional metal curtain walls use sealing and gluing technology to ensure watertightness and airtightness. However, the use of silicone glue to seal the joints on site makes the joints easy to accumulate dust and pollute the surface of the curtain wall. In addition, the internal and external pressure difference cannot be eliminated. When the structure is displaced and deformed, once the sealant cracks, it will be a hidden danger of water seepage. And because the four sides are fixed with screws, it is difficult for the metal plate to eliminate the influence of thermal expansion and contraction on it. The surface of the metal plate is easy to deform, forming a bulge phenomenon, which affects the flatness of the curtain wall.
[0003] At present, there is a slotted metal curtain wall system, which uses a glueless process in the joints of metal panels. The slots allow the air layer behind the metal panels to flow smoothly, which can achieve good insulation and sound absorption effects. However, this slotted metal curtain wall system still has shortcomings in terms of waterproof performance, especially in high-rise buildings and rainy areas, where the waterproof problem is more prominent.
