The construction and application of the unit curtain wall system of the steel-aluminum combination

Curtain walls are widely used in the epidermis of buildings. At present, the unit curtain wall system production frame is mainly aluminum profile. But taking into account the weak aluminum strength and soft characteristics, the existing curtain wall often ensure the frame carrying capacity by increasing the amount of aluminum per unit area, which makes the high curtain wall costs. At the same time, the nodes of its production process are complex and require higher functions of production equipment. In this paper, a unit curtain wall system of steel-aluminum combination is proposed, which has the characteristics of simple construction, processing and installation, consisting of three key technologies including new steel-aluminum material combined with keel frame technology, glass curtain wall installation technology and cross-stitch node waterproofing technology. The system (1) in the construction, the integration of the concept of just soft. The unit structure of “steel column and aluminum profile” plays an advantage of high steel structure strength to ensure carrying capacity. In addition, the aluminum profile is fully plastic and the shape can be controlled. (2) In the production mode, the unit curtain wall is prefabricated by factory flow watering, and the processes are independent of each other, which is convenient for organizing processing equipment. (3) In the installation, the roof ring track and hoist are used to lift the unit plate, which avoids adverse shaking and rotation, reduces the risk of high-altitude operation and shortens the duration. This technology is of great reference significance to the construction of curtain wall of high rise buildings.
