The application and development of aluminum formwork technology abroad has a history of more than 50 years and is widely used in various fields of reinforced concrete building structures. It has been widely used in the buildings of developed countries such as the United States and Canada, as well as emerging industrial countries such as Mexico, Brazil, Malaysia, South Korea and India. In the process of popularization and use, countries have also accumulated a lot of experience in the design, manufacture, application and construction of aluminum formwork. The annual aluminum template Market in the United States is about US $100 million, which is divided up by four or five local aluminum template manufacturing companies. In Mexico, aluminum alloy formwork technology is also widely used in affordable housing. Just take an aluminum formwork manufacturing company headquartered in Colombia as an example. During the term of President Fox of Mexico, it participated in the construction of more than 1 million affordable houses with its aluminum formwork technology. Ten years ago, South Korea mainly used plywood. So far, 80% of its high-rise residential buildings have adopted aluminum formwork technology.

Looking at the foreign formwork technology, in the cast-in-situ concrete structure project, due to the expensive labor force, the formwork project generally accounts for 50% ~ 60% of the project cost. Therefore, foreign countries attach great importance to the selection of formwork materials. The material structure of aluminum formwork abroad mainly includes: ① high quality wood plywood formwork, aluminum I-beam and aluminum rib are assembled into wall or floor formwork; ② Wood based panel formwork of aluminum frame (various wood plywood, plastic board and other new material surfaces), in which the large formwork is used for walls and columns, and the smaller specification is used for floors and beams; ③ aluminum formwork and aluminum support system are assembled and poured as a whole according to the shape of building structure, with large and light single area, simple assembly and disassembly, many times of turnover and use, high construction efficiency and good fair faced concrete effect.
