Introduction of basic knowledge of curtain wall

composed of the panel and supporting structure system (supporting device and supporting structure), relative to the main body has certain displacement ability or certain deformation ability, do not bear the role of the main structure.The curtain wall is the outer wall enclosure of the building, which does not bear weight, hangs like a curtain, so it is also known as the hanging wall. It is a light wall with decorative effect in modern large and high-rise buildings.Building envelope structure composed of structural frame and inlaid panels that does not bear the load and action of the main structure.

Development of curtain wall technology
A, from bulky to lighter sheet and structure (Natural stone thickness 25mm, new material thinnest to 1mm)
B, varieties are gradually reduced to many types of plates and richer colors (at present, stone, ceramic plate, micro-crystal glass, high pressure laminate, cement fiber dimension plate, glass, inorganic FRP, nearly 60 plates, metal plate are applied in the outer wall)
Higher security performance
D, more flexible, convenient and fast curtain wall construction technology
E, higher waterproof performance, prolong the life of the curtain wall (from closed to open curtain wall)

curtain wall industry development
With the continuous competition of the construction curtain wall industry, the merger and integration and capital operation between large building curtain wall enterprises are increasingly more frequent, and the domestic excellent curtain wall manufacturers pay more and more attention to the research of the industry market, especially the in-depth study of the enterprise development environment and the change of customer demand trend.Because of this, a large number of domestic excellent building curtain wall brands rose rapidly, and gradually become the leader in the building curtain wall industry!By the end of 2010, the total output value of China’s construction curtain wall industry had increased from 62 billion yuan in 2005 to 150 billion yuan, with an increase of 142% and an average annual growth rate of 19%, showing an extremely strong development trend.The workforce also grew to more than 90,000 people.China’s construction curtain wall industry started in 1983, and is the product of China’s economic system reform. Compared with other traditional industries, the young curtain wall structure is relatively less affected by the planned economic system.Nowadays, private enterprise groups, Chinese-foreign joint venture, joint stock and limited liability company, and the competition pattern with non-public economy as the main body has gradually formed.
Analysis of the output and market trend of the construction curtain wall industry
& quot; During the 12th Five-Year Plan & quot; period, China will vigorously develop building energy conservation-related industries, and China will carry out energy-saving transformation of 570 million square meters of buildings, which is undoubtedly an opportunity for the rapid development of the building curtain wall industry.
