Variety Of Steel Formwork And Scope Of Application

Profiled steel formwork is an engineering formwork material that uses galvanized or anti-corrosion-treated thin steel plates and is cold-rolled by a forming machine into a channel-shaped steel plate with a trapezoidal wave section or an open square box-shaped steel shell.
Profiled steel formwork is mainly divided into profiled steel plates of combined plates and profiled steel plates of non-combined plates from their structural functions.
1. The profiled steel plate of the composite plate
It is both a formwork and a tensile reinforcement for the bottom surface of the cast-in-place floor slab. The profiled steel plate not only bears the construction load and the self-weight of the cast-in-place steel bars and concrete during the construction phase, but also bears the service load during the use phase of the floor slab, thus constituting a component of the floor slab structure.
This kind of profiled steel plate is mainly used in the cast-in-place reinforced concrete floor slab project with beams and ribs in steel structure houses.
2. Profiled steel plate of non-combined plate
It is only used as a template. That is to say, the profiled steel plate only bears the construction load and the self-weight of the reinforced concrete of the cast-in-place layer during the construction stage, but does not bear the use load during the use stage of the floor slab, and only constitutes a non-stressed component of the floor slab structure.
This kind of formwork is generally used in cast-in-situ densely ribbed floor slab projects with beams or beams in steel structures or reinforced concrete structures.
