Requirements for verticality and flatness of aluminum molds

The verticality and flatness requirements of aluminum formwork are 2mm vertical and 3mm flat.

Aluminum alloy formwork is called aluminum alloy formwork for concrete engineering, which is a new generation formwork system after plywood formwork, composite steel formwork system, steel frame wood-bamboo plywood system, large formwork system and early dismantling formwork system.

Aluminum alloy formwork is made of aluminum alloy profile as the main material, which is processed and welded. It is suitable for concrete engineering. It is designed by 50mm modulus and consists of panel, rib, main profile, plane formwork, corner formwork and early dismantling device.

The design and construction application of aluminum alloy formwork is the innovation of concrete engineering formwork technology, the promotion of assembled concrete technology and the embodiment of construction technology industrialization.

All-aluminum alloy formwork technology originated in the United States in the 1950s. Since its implementation in developed countries such as the United States and Canada, it has been gradually tried by Mexico, Brazil and other countries in the field of architecture in Malaysia, South Korea, Japan, India and other Asian countries, and has been widely used in subsequent development, mostly for high-rise residential construction.

After 2000, China gradually introduced all-aluminum formwork technology from neighboring countries in Asia and Hong Kong, and gradually replaced the original bamboo plywood, wood formwork and steel formwork with all-aluminum formwork in the construction field, and gradually promoted aluminum formwork in coastal cities, and established new aluminum formwork production enterprises in Foshan, Guangdong and other places earlier to promote the application of aluminum formwork technology in China.

Especially since 20 16, the application of aluminum alloy formwork has reached a climax. Since 20 19, Liaoning Zhongwang, Yike Aluminum Mould, GETO Zhite, SNTO Shengtong, Guangya Aluminum Mould, Tonglide and Changyi have occupied a large market share.
