The building formwork structure used in the construction of cast-in-place concrete structures mainly consists of three parts: panels, support structures, and connectors. The panel is a load-bearing plate that directly contacts the newly poured concrete; The supporting structure is a temporary structure that supports the panels, concrete, and construction loads, ensuring that the building template structure is firmly combined and not deformed or damaged; A connector is a component that connects a panel to a supporting structure as a whole.

Building formwork is the shell and support formed by concrete pouring, which can be divided into building formwork, building wooden plywood, laminated board, multi-layer board, double-sided adhesive, double-sided laminated building formwork, etc. according to the properties of the materials. Building templates can be divided into cast-in-place concrete templates, pre assembled templates, large templates, and jumping templates according to construction process conditions.

Composite steel formwork is a new type of formwork that has the advantages of strong universality, convenient installation and disassembly, and multiple turnover times in modern formwork technology. It can be used for cast-in-place reinforced concrete structure construction, and can be assembled into large formwork for beams, columns, walls, and floors according to design requirements in advance. It can be lifted in place as a whole or disassembled in bulk. [1]

Aluminum template, a new type of building template made of aluminum alloy, and a newly emerging green construction template in the construction industry, are adopted by various construction companies due to their characteristics of simple operation, fast construction, high return, environmental protection and energy conservation, frequent use, good concrete pouring effect, and recyclability. On November 27, 2014, at the "Expanding the Application of Aluminum in the Construction Industry High Level Forum", it was proposed to expand the application of aluminum templates, focus on promoting aluminum templates, and implement aluminum template construction standards as soon as possible.
