What is the curtain wall? What types does it have?

Curtain wall is a kind of external wall enclosure component hanging outside the framework of building structure. Its self-weight, wind load and earthquake action are transmitted to the main frame of the building by point transmission through staggered joints. The joints and connections between curtain wall components are treated by modern building technology, so that the curtain wall forms a continuous wall. ?

1, which can be divided into glass curtain wall, metal curtain wall, stone curtain wall and composite curtain wall according to panel materials.

2. According to the frame material, it can be divided into aluminum alloy curtain wall, color steel curtain wall and stainless steel curtain wall.

3. According to the method of fixing glass, it can be divided into: open frame glass curtain wall, (fixing glass with Sichuan mosaic groove) and hidden frame slope glass curtain wall (fixing glass with structural glue seam).

4. According to the processing degree of the factory and the installation technology of the main structure, it is divided into component curtain wall and unit wall.

Advantages of curtain wall

1, the visual effect is good. The application and popularization of glass in building engineering is the most outstanding achievement of modern architecture in the application of new technologies, new structures and new materials.

2. The weight of the wall itself is very light. The weight of glass curtain wall and metal curtain wall is 65,438+0/7 ~ 65,438+0/8 of precast concrete wall and 65,438+0/65,438+00 ~ 65,438+02 of brick wall, which greatly reduces the pressure on the main structure and foundation.

3. Less materials, mainly modern industrial products. Most processes are processed in the factory (especially the unit curtain wall). Its performance is stable, the machining accuracy is high and easy to control, the workload of on-site installation is less, it is less affected by rainy season and other weather, and the construction period is short.

4. The replacement and maintenance of curtain wall components are convenient and the maintenance cost is low.

5. Increase indoor air permeability and improve comfort.

6. The structural form of the building curtain wall can be designed and selected according to the modeling needs of the building, which can better adapt to the transformation and renewal of the old building facade. Building curtain wall organically combines the mechanical properties, such as wind and rain resistance, thermal insulation, lighting and sound insulation, and decorative functions of building envelope, and is a synthesis of architectural art, function and technology.
