The building formwork is used to support the concrete pouring. After the concrete pouring is formed, the formwork shall be removed. It is a temporary support structure, which is made according to the design requirements, so that the concrete structure and components are generally formed according to the specified position and geometric size, maintain a 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 cost of the project.
In fact, the building formwork is a temporary support structure, which is manufactured according to the design requirements, so that the concrete structure and components can be formed according to the specified relevant positions and geometric dimensions, maintain the correct position of the building formwork support, and bear the self weight of the building formwork and the external load acting on it. The purpose of formwork works is mainly to ensure the quality and construction safety of concrete works, speed up the construction progress and reduce the project cost. The main purpose of the building formwork is to form and maintain the newly poured concrete, so that it can reach a certain strength to bear the self weight of the temporary structure and can be removed.
The building formwork structure used in the construction of cast-in-place concrete structure 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 supporting the panel, concrete and construction load to ensure that the structure of the building formwork is firmly combined without deformation and damage; The connector is a kind of accessory that connects the panel and the supporting structure as a whole.
Building formwork is a form shell and support formed by concrete pouring. According to the properties of materials, it can also 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.
