Architectural curtain wall as early as 150 years ago (the middle of the 19th century) has been used in the construction engineering, due to the limitation of materials and processing technology, curtain wall to reach absolute water tightness, air tightness and resist various natural forces (wind, earthquake, temperature), the attack of thermal physical factors (thermal radiation, condensation) and sound insulation, such as fire prevention requirements, Has not been very good development and promotion. Since the 1950s, due to the rapid development of building materials and processing technology, successfully developed various types of building material, such as the invention of a variety of sealant, and other filling materials of sound insulation, fire prevention, well solved the index requirements for curtain wall building periphery, and gradually become a new trend of contemporary exterior architectural decoration.
With the development of science and technology, people's demand for different functions of curtain wall structure has been improved, and architectural curtain wall has developed into a science with complete system and mature technology. Building curtain wall on behalf of the development of modern construction technology, is a blend of architectural art, construction technology, in recent years, with the development of material manufacturing technology innovation, new emerged more and more curtain wall materials, and the tradition of the curtain wall compared several big adornment material in manufacturing process, adornment effect, installation technology, energy conservation, environmental protection and other aspects have a great progress. Building Curtain Wall is classified according to its panel materials, mainly divided into stone curtain wall, glass curtain wall, metal curtain wall and other three categories. The most representative "glass box" is the Lihua Tower in New York built in 1952, which is the first application of glass curtain wall in the high-rise project. In the decades that followed, glass, aluminum alloy and steel were considered symbols of modern high-tech development in architecture and favored by architects. Metal curtain wall is a kind of architectural decoration that has been developed since the second World War. Due to the overproduction of aluminum after the war, it was used in a large number of boxes in the building, tin alloy curtain wall can be widely used.
Hangzhou Biological Science and Technology Building, two super high-rise cylindrical structure buildings, stands beside the Qiantang River in Hangzhou. The height of the building is 130 meters, and its curtain wall facade is made of super-large ceramic sheet curtain wall. The appearance of the project means that the super specification building ceramic plate is formally applied to the curtain wall of super high-rise buildings. Its characteristics of light weight, rich color, energy saving and environmental protection, convenient construction and low cost have attracted the attention of the architectural circle, indicating that the curtain wall industry has more than a new material to give architects more choices.
