Curtain walls and windows need attention about the quality of the overall qualit
With the construction industry in China in recent years the rapid development of Aluminum alloy doors and windows Increased production, according to China Construction Metal Structure Association Statistics Committee of aluminum curtain walls and windows, aluminum doors and windows in 2003 China's output of 2.8 million square meters in 2005 to 320 million square meters, 365 million square meters in 2007, shows that China is real power doors and windows. In a large wall unit curtain wall manufacturing company in the ratio of the framework already accounts for 60%%, curtain wall, of which double wall Project A significant increase in the proportion, not only the needs of curtain wall business breeding, but also reflects the building all walks of life Energy Overall increase overall awareness. Among them, the great wall company in Shenyang in 2008 total sales 18 billion yuan, up 17%; Shenzhen, Guangdong, curtain wall company to take gold in Guangzhou TV Tower, Guangzhou West Tower and other special high-rise building curtain wall engineering, curtain wall engineering design for the domestic high-rise construction has accumulated rich experience.
In production, China is undoubtedly the use of aluminum curtain walls and windows and manufacturing country. Curtain walls and windows as the building envelopes, the quality of the project is especially important in this annual meeting, the China Construction Metal Structure Association, Yao Bing new ideas from the engineering quality windows and doors curtain wall industry innovation and development perspective to explain the project quality and aluminum curtain wall windows intrinsic link between. Yao Bing that the curtain walls and windows as the enclosure structure should also be a reasonable service life, should be timely replacement; quality curtain walls and windows are closely related with the building as a whole; window curtain business should be based on existing trails.
Window curtain should have a reasonable life
Yao Bing, said that any buildings have life, civil construction for 50 years, major construction 100 years. Beijing developed specifically for engineering structures reward system, indicating the quality of the structure of the building is essential. Window curtain wall construction is not only decorative, it is the enclosure structure is an important part of building structures. Window curtain wall construction of the external structure, as there must be a reasonable life.
80s last century, China's aluminum windows and curtain wall at the beginning, from Germany, Italy, Japan, the United States copied the number of building curtain wall project. Later, it was suggested that the glass curtain wall of light pollution, after 80s of last century, a number of large public buildings in large quantities using the curtain wall, curtain wall facades Decorative Materials Use has changed quite a large area of the all-glass curtain wall is gradually reduced, then heard the sound of light pollution is not too much. Replacement during this period is a new era of building curtain wall, curtain wall is a comprehensive update to the era. Yao Bing suggested that he was more concerned about the last century before the 50's who works, the structure prone to problems, and even reinforced concrete high-rise buildings, worried that one day suddenly fell down. Therefore, building curtain walls and windows as a very important building products, replacement of the same problems exist.
Prevention capacity is a measure of the importance of the quality of building structure, the building can not fail to consider prevention. For example last year's earthquake, causing serious damage to the building. Earthquakes are natural to the architectural structure of a destructive test, usually we can not do such a destructive test. There is a typhoon, typhoon in China is a multi-national, coastal areas of the curtain walls and windows of the wind pressure capacity requirements higher. Waterproof doors and windows is an important issue. Economically developed regions, with increased productivity, the use of curtain wall construction is relatively greater, the stricter the demands of the building. In coastal areas, typhoons and tsunamis from time to time in a test of our building, in 1988, a typhoon in Guangdong Shantou area to scratch a lot of aluminum windows and doors, aluminum doors and windows at our state standards are not stringent enough, some of the works using the thin aluminum materials produced with 0.8 mm aluminum windows and doors, of course not withstand typhoons. After this incident from the aluminum doors and windows in China increased the aluminum wall thickness requirements, significantly improving the quality of aluminum doors and windows.
Fenestration quality about the overall quality of construction
Yao Bing that doors and windows and doors and windows accessories has a lot. Architectural detail is very important, doors and windows closed after the four to take the air, housing wall leakage, surface quality defects such as cracking, it seems not a big issue, but the victims are civilians.
