What is a building template?

The building formwork is a temporary support structure, which is manufactured according to the design requirements to form the concrete structure and components according to the specified position and geometric size, maintain their correct position, and bear the self weight of the building formwork and the external load acting on it. The purpose of formwork engineering is to ensure the quality and construction safety of concrete engineering, speed up the construction progress and reduce the project cost.

The building formwork structure used for the construction of cast-in-place concrete structure engineering is mainly composed of three parts: panel, support structure and connector. The face plate is a bearing plate that directly contacts the fresh concrete; The supporting structure is a temporary structure that supports the panel, concrete and construction load to ensure that the building formwork structure is firmly combined without deformation and damage; Connectors are fittings that connect the panel to the support structure as a whole.

Building formwork is a form shell and support formed by concrete pouring. According to the properties of materials, it can be divided into building formwork, building wood plywood, coated plate, multilayer board, double-sided adhesive coating, double-sided coated building formwork, etc. According to the construction process conditions, building formwork can be divided into cast-in-place concrete formwork, pre assembled formwork, large formwork, jump formwork, etc.

The combined steel formwork is a new type of formwork with the advantages of "replacing wood with steel" in modern formwork technology. It can be used for the construction of cast-in-place reinforced concrete structures. The large formwork of beams, columns, walls and floors can be assembled in advance according to the design requirements, hoisted in place as a whole, or disassembled in bulk.

Aluminum formwork, a new building formwork made of aluminum alloy, and a new green construction formwork in the construction industry, are adopted by various construction companies with the characteristics of simple operation, fast construction, high return, environmental protection and energy conservation, many times of use, good concrete pouring effect and recyclability. On november27,2014, at the "high level Forum on expanding the application of aluminum in the construction industry", it was proposed to expand the application of aluminum formwork, focus on promoting aluminum formwork, and implement aluminum formwork construction standards as soon as possible.
