Formwork is a temporary support structure, made according to the design requirements, so that concrete structures and members are shaped according to the specified position and geometry, keep their correct position, and bear the self-weight of the construction formwork and the external load acting on it. The purpose of a formwork project is to ensure the quality of the concrete project and construction safety, speed up the construction progress, and reduce the project cost, there are many different formworks collectively referred to as formwork systems, therefore, it is necessary to classify formwork systems.
●Classification by material
●Classification by Construction type
Classification by material
The formwork systems are divided into wood formwork, steel-wood formwork, steel formwork, steel bamboo formwork, plywood formwork, plastic formwork, etc.
wood formwork
The species of wood formwork can be selected according to the actual situation of each region, and most of them are pine and fir. Due to the large consumption of wood formwork and the low rate of repeated use, to save wood, the use of wood formwork should be minimized or not used in the cast-in-place reinforced concrete structure. The steel-wood formwork is a stereotyped formwork with angle steel as the frame and wood as the panel. Its advantages are that it can fully use short wood and can be used repeatedly.
Plywood formwork
Plywood formwork is a stereotyped formwork with plywood as the panel and angle steel as the frame. With plywood as the panel, the uneven directionality of wood is restrained, and the stress performance is good. This kind of formwork has the advantages of high strength, small dead weight, no warping, no cracking, large plate width, and few joints. The steel and bamboo formwork is a shaped plate with angle steel as the frame and bamboo woven plywood as the panel. This kind of formwork has large rigidity, is not easy to deform, is light in weight, and is easy to operate.
Steel formwork
Steel formworks are generally made into stereotyped formworks, which are assembled into various shapes and sizes with connecting members. They apply to various construction methods and are widely used in cast-in-place reinforced concrete construction. The one-time investment in steel formwork is large, but the turnover rate is high. In the process of application, attention should be paid to storage and maintenance to avoid rusting to extend the service life of steel formwork.
Other formwork
Plastic formwork, glass fiber reinforced plastic formwork, and aluminum alloy formwork have the characteristics of lightweight, high rigidity, convenient assembly, and high turnover rate, but they have not been widely used in construction due to high cost.
Classification by Construction type
Due to the different shapes, sizes, and structures of various cast-in-place reinforced concrete structural members, the structure and assembly methods of the formwork are also different, forming their characteristics. According to the type of construction, the formwork systems are divided into foundation formwork, column formwork, beam formwork, floor formwork, stair formwork, wall formwork, shell formwork, chimney formwork, etc.
