Aluminum formwork is a building formwork made of aluminum alloy, also known as aluminum alloy formwork. It is designed according to the module. The aluminum formwork is made by extrusion of special equipment. It is composed of three parts of aluminum panel, bracket and connector. It has complete supporting universal accessories. It can be assembled into a complex overall formwork of different sizes. The system formwork of assembly and industrial construction solves the defects of traditional formwork and greatly improves the construction efficiency.

The design, development and construction application of aluminum formwork is a major development in the construction industry.

Aluminum formwork has been widely used in buildings in developed countries such as the United States and Canada, as well as emerging industrial countries such as Mexico, Brazil, Malaysia, South Korea and India.

The components of the aluminum formwork system need to be designed according to the characteristics of the floor, which requires high capabilities of design technicians. About 80% of the modules in the aluminum formwork system can be recycled in multiple projects, while the remaining 20% ​​can only be recycled in a class of standard floors. Therefore, the aluminum formwork system is suitable for super-high-rise buildings or multi-story buildings and villas with a high degree of standardization. The following technical advantages can be particularly reflected in areas with a high degree of urbanization:

1) Short construction period. The aluminum formwork system is a quick-disassembly formwork system. A set of formwork can be constructed in four days, and the assembly line construction can be carried out well, which greatly improves the construction progress and saves management costs.

2) It is reused many times and has a low average use cost. The aluminum formwork system uses aluminum alloy profiles formed by integral extrusion as raw materials. A set of formwork can be flipped and used more than 300 times in standardized construction. The purchase price of a set of formwork is amortized to save a lot of cost compared with traditional formwork.

3) Convenient construction and high efficiency. The aluminum formwork system is simple and convenient to assemble, with an average weight of about 20kg. It is completely carried and assembled by hand without the assistance of any mechanical equipment. In addition, the system design is simple, and the workers can get started quickly and the template flipping speed is very fast. Skilled installation workers can install 20-30 square meters per day, which greatly saves labor costs.

4) Good stability and high bearing capacity. The bearing capacity of most aluminum formwork systems can reach 60KN per square meter, which is enough to meet the formwork bearing capacity requirements of most residential buildings.

5) Wide range of applications. Aluminum formwork is suitable for use in walls, horizontal floors, columns, beams, stairs, window sills, floating boards and other locations. It is also useful for secondary structural formwork such as ring beams, structural columns, and anti-sills.

6) Few joints, high precision, and good concrete surface effect after demolding. After the aluminum building formwork is demolded, the concrete surface quality is flat and smooth, basically meeting the requirements of finishing and clear water concrete, without the need for plastering, which can save plastering costs.

7) There is less garbage on site and the support system is simple. All accessories of the aluminum formwork system can be reused. After the construction and demolding, there is no garbage on site. The support system is simple in structure and easy to dismantle, so the entire construction environment is safe, clean and tidy.

8) Standard and strong versatility. Aluminum formwork has many specifications and can be assembled with different specifications of plates according to the project; when the used formwork is converted into a new building, only about 20 non-standard plates need to be replaced, which can reduce costs.

9) High recycling value. After the aluminum formwork is scrapped, when the waste treatment residual value is high, the cost amortization advantage is obvious.

10) Low carbon emission reduction. All materials of the aluminum formwork system are renewable materials, which meet the national regulations on energy conservation, environmental protection, low carbon and emission reduction of construction projects.
Aluminum formwork construction is popular mainly because its technical indicators are more advanced and can better meet the requirements of the country and society for construction projects.
