The building formwork is a temporary supporting structure, which is made according to the design requirements, so that the concrete structure and members are shaped according to the specified position and geometrical dimensions, maintaining their correct position, and bearing the self-weight of the building formwork and the external load acting on it. The purpose of the template project is to ensure the quality of concrete works and construction safety, speed up construction progress and reduce engineering costs.
The building formwork structure used for the construction of cast-in-place concrete structures is mainly composed of three parts: panel, support structure and connecting parts. The panel is a bearing plate directly contacting the newly poured concrete; the supporting structure is a temporary structure supporting the panel, the concrete and the construction load, ensuring that the building formwork structure is firmly combined so as not to be deformed or damaged; the connecting piece is the panel and the supporting The structure is connected to an integral fitting.
The building formwork is a formwork and bracket for concrete pouring. According to the nature of the material, it can be divided into building formwork, building wood glue board, laminated board, multi-layer board, double-sided compound glue, double-sided film building formwork and so on. According to the construction process conditions, the building formwork can be divided into cast-in-place concrete formwork, pre-assembled formwork, large formwork, jump formwork and so on.
The combined steel formwork is a new type of “steel-made wood” which has the advantages of strong versatility, convenient assembly and disassembly, and many turnover times. It can be used for the construction of cast-in-place reinforced concrete structures. According to the design requirements, the large-scale formwork of beams, columns, walls and floors is assembled, and the whole lifting is in place, and the bulk disassembly method can also be adopted.
Aluminum formwork, new building formwork made of aluminum alloy, green construction formwork emerging from the construction industry, with simple operation, fast construction, high return, environmental protection and energy saving, many times of use, good concrete pouring effect, recyclable, etc. Adopted by the company. On November 27, 2014, in the “Expansion of Aluminum in the Construction Industry Application High-Level Forum”, it was proposed to expand the application of aluminum formwork, focus on the promotion of aluminum formwork, and implement the aluminum formwork construction standards as soon as possible.
