Guangxi to promote aluminum alloy formwork

According to the bulk non-ferrous net reprinted: A new technology that can effectively cure hollowing, cracking and other construction quality defects will be promoted in Guangxi Zhuang Autonomous Region. Recently learned from the Autonomous Region Housing and Urban-Rural Development Department and the Urban and Rural Construction Committee of Nanning City on the spot to observe the construction of aluminum alloy formwork technology. It is understood that the use of aluminum alloy formwork technology (hereinafter referred to as "aluminum mold technology") construction, the concrete wall column after partial treatment can be directly after the decoration operation, home buyers no longer have to worry about empty walls, cracking and other issues.

After observing the Vanke Charm City site in Wuxiang New District, Nanning, a person in charge of the construction company discovered that there was no construction waste on the aluminum mold construction site compared to the traditional wood formwork technology. After the aluminum alloy formwork was removed from the mold, the wall could be removed. Ash process. He said: "The inner and outer walls of the building are not plastered. After the templates are removed, they can be directly renovated. Buyers do not have to worry about empty walls, cracking, etc."

It is understood that although wood formworks still occupy a dominant position in the construction market of the autonomous region, there are problems such as the low number of recycling operations and the large loss of wood during processing. Steel formwork has the problems of heavy materials, inconvenient construction, rust corrosion, and deformation. “Accordingly, the application of aluminum alloy formwork has become the choice for energy saving and emission reduction in the construction industry.” The person in charge of the Autonomous Region Housing and Urban-Rural Development Office stated that in addition to energy saving and environmental protection, the aluminum mold technology has the advantages of short construction period, reusability, and other advantages. Construction costs. In addition, aluminum mold technology has better stability and higher bearing capacity. These are the primary conditions for homebuyers to buy a quality house. "Energy conservation and emission reduction, good comprehensive economic benefits, and recyclability are major highlights of this new process." Yang Lufeng, deputy director of the Ministry of Housing Urban and Rural Development of the Autonomous Region, said that using aluminum mold technology not only can eliminate the plastering of concrete walls. Processes, with the overall construction technology such as cast-in-situ exterior walls, can also completely eliminate internal and external wall plaster, reduce wet operations, solve the traditional process plaster layer emptying, cracking and other common problems.

According to statistics, in 2014, the country’s housing completed area was 1,106.59 million square meters. According to the consumption of 0.027 cubic meters of timber per square meter of building facade, and 0.7 cubic meters of timber per tree, there were only 20,739 thousand hectares of the country in 2014 alone. The forest disappeared. The aluminum alloy template can be recycled about 150 times under normal conditions. Because the aluminum alloy template greatly improves the flatness of the wall surface, the main structure part of the wall surface does not need to be plastered again, and the economy is realized. Taking Nanning Vanke's 2015 residence as an example, the construction area of ​​the aluminum mold technology is 380,000 square meters. After calculation, it can save 102.6 million cubic meters of wood, and eliminating the plastering process can save 11,400 cubic meters of mortar.

It is reported that the relevant state departments have begun to prepare aluminum alloy formwork industry standards, Guangdong, Fujian, Yunnan and other provinces have also issued a regional "aluminum alloy formwork technical regulations." The Nanning Urban-Rural Construction Committee has submitted an approval for the “Guangxi aluminum alloy formwork technical specification” declared by the Autonomous Region Housing and Urban-Rural Development Department. In the future, this new construction technology will be gradually used in Guangxi.
