Composite steel formwork is a kind of tool formwork, which is composed of few types of plates and accessories with a certain modulus. It can spell out geometric shapes of various sizes to meet the construction needs of beams, columns, plates, walls and foundations of various types of buildings. It can also be used to spell formwork plates, tunnel formwork and flying formwork.

Advantages: the plates and accessories of the combined steel formwork are light and flexible, easy to assemble and disassemble, and can be assembled and disassembled manually, saving carpentry; There are many times of turnover during use. Each set of steel formwork can be reused for more than 50-100 times. After 25 times of use, all the investment can be recovered, and the amortization cost each time is lower than that of wood formwork; The combined steel formwork has high processing accuracy, the best quality of pouring concrete, accurate size of formed concrete, neat edges and corners and smooth surface, which can save decoration labor

Classification: plane formwork, internal corner formwork, external corner formwork and connecting corner formwork.

1. Plane formwork

Plane formwork is used for plane parts of various structures such as foundation, wall, beam, slab and column. It is composed of a panel and ribs, and the thickness of the panel is 2 3mm or 2.5mm 5mm。 The rib is provided with a U-shaped card hole, which is assembled into a large plate by using a U-shaped card and an L-shaped bolt.

2. Internal corner formwork

Internal corner formwork is used for internal corners of concrete components, such as internal wall corners or internal corners of pool walls and internal corners at the junction of beams and slabs.

3. External corner formwork

External corner formwork is mainly used for external corners of concrete components.
