Aluminum template, all known as the construction of aluminum alloy template system. It is a new generation of new type of formwork support system, which is followed by bamboo wood formwork and steel formwork. The application of aluminum formwork system in the construction industry has improved the overall construction efficiency of the construction industry, including a lot of savings in building materials and manual arrangement.

The role of formwork in concrete engineering is very important. In cast-in-place concrete structure engineering, formwork engineering generally accounts for 10% - 20% of the cost of concrete structure, which accounts for 30% - 40% of the engineering labor volume, accounting for about 50% of the construction period. The template technology has an important influence on improving the quality of the project, speeding up the construction progress, reducing the cost of the project and realizing the civilized construction. In engineering quality, the quality of the construction of the formwork is directly affected by the quality of the formwork.

Our current template level is still very backward, the last century before 80s, the cast-in-place structure template is mainly used in China wood. The last century at the end of 70s, from Japan to introduce the development of the combined steel formwork, since 90s of last century, due to a combination of steel plate size is small, the seam template exists, it is difficult to adapt to the needs of engineering construction has gradually withdrawn from the market. After 1996, Beijing began a large number of application of all steel large formwork, steel formwork is heavy (46 - 80kg/m2), must rely on the tower crane, steel template itself does not become a complete template system, wall, column can be vertical, horizontal template (including windows) and generally need to use wood template. With the rapid development of China's architectural engineering technology, the backwardness of the template technology in China is extremely disproportionate. The specialization of the construction project is becoming more and more fine. In concrete structure engineering, the commercialization and specialization of concrete has been realized. The specialization and specialization of formwork construction will also be the inevitable trend of development.

Aluminum alloy formwork is a new generation of building formwork, which can be seen in more and more places in the developed countries of the world. The main advantage of the aluminum template is that the effect of energy saving and emission reduction is remarkable. Aluminum is a renewable material, and the aluminum template can turn 200 to 300 times, while the wood template is only 3 to 5 times. Aluminum 25 to 30 kg per square meter aluminum template, recovery value of about 300 yuan. The use of aluminum templates instead of wood formwork can greatly reduce the use of wood. Last year, the amount of building templates in China was more than 800 million square meters. If 20% of them were replaced by aluminum templates, they could save 160 million square meters of wood templates, equivalent to 400 thousand tons of standard coal and 1 million tons of carbon dioxide emissions. It is understood that the Ministry in the "non-ferrous metals industry" 13th Five-Year "development plan" in the preparation, application will encourage the construction aluminum template, aluminum foam, aluminum structure housing seismic activities of the board to expand in the field of architecture.

In addition, aluminum wood or steel formwork installation than 3 to 5 days, the construction speed, and good stability, strong bearing capacity, smooth concrete surface quality, reduce wall plastering process, good quality.

At present, Aluminum Alloy template instead of the traditional template have been widely used, and with its light weight, high strength, large size plate, the characteristics of little seam effectively ensure the construction quality. Although the early investment of aluminum alloy template is relatively high, it can effectively shorten the construction period, improve the quality of construction, and reduce unnecessary trouble caused by the two construction.

Aluminum Alloy template can form a complete system, its design is standardization and specification of diverse characteristics, one can complete the wall, column, beam and plate, balcony, windows, and decorative lines of concrete structure construction, so that it can adapt to any position of the installation and construction, and make the degree of standardization construction the project has been effectively protect and improve. At the same time, the aluminum alloy formwork system is supported by independent steel, which is very simple and can replace the traditional wood form and support. Because the aluminum alloy template is very light, low degree of dependence on machinery, can not need to use the tower crane, completely by manual transfer.
