Pull-rod system aluminum alloy formwork consists of formwork system, fastening system, supporting system and fitting system, which has complete supporting formwork system, it is suitable for the formwork system in different areas such as urban pipe corridor, public buildings and residential buildings. Pull sheet system aluminum alloy formwork is composed of formwork system, support system, accessories system, with a complete supporting formwork system, generally suitable for residential buildings. According to the structural form of the template system is divided into plane template, corner template and components. The corner formwork comprises a positive corner formwork, a negative corner formwork and a negative corner formwork, and components include a single inclined aluminum beam, a double inclined aluminum beam, a floor slab early removal head, and a beam bottom early removal head. Support system is divided into steel support, aluminum support, other support. The fastening system is divided into two types according to the forms of the forces: steel-backed ribbed reinforcement and pull-to-pull reinforcement, the reinforcement is divided into aluminum-backed, steel-backed, light-weight steel keel-backed, other alloy-backed, square-pipe-backed and so on. Aluminum alloy template is divided into standard template and non-standard template according to the general form. In accordance with the height of the edge ribs 65mm, aperture 16.5 mm, hole center in the face plate distance 40mm, length, width, hole center distance according to 50mm integral times of the rectangular flat plate, corner template and shape unity of common components, are standard plates. A template or component that does not meet one of the above conditions is a non-standard template. Non-rectangular templates and non-conventional components are not included in the range of identification of the above-mentioned standard and non-standard components
