The steel structure floor adopts profiled metal plate as permanent support, and the formwork works together with the cast-in-situ reinforced concrete structural layer to form the permanent composite structure of the building. It is used to be called structural floor bearing plate.
The floor bearing plate also includes baffle, sealing plate, edge closing plate and other auxiliary components. The floor bearing plate is laid and connected with the steel beam, the plate end is welded with the steel beam through penetration spot welding, and the middle is welded with the steel beam through penetration stud.
Steel bearing plate is an important supporting product of steel structure building, which has the advantages of simple and fast construction and short construction period; Replace the traditional template and improve the shortcomings of the traditional template; It can be used as a part of structural strength to reduce material cost; Easy construction of reinforcement, wiring and piping; Clean and beautiful appearance; It has the characteristics of light weight, high strength, large bearing capacity and good seismic capacity. Floor bearing plate belongs to the main category of profiled steel plate. Sometimes profiled steel plate can also refer to floor bearing plate, which is formed by pressing galvanized sheet, with a thickness of 0.7-1.5mm. That is, the steel bearing plate of floor structure, which is characterized by:
1. No formwork is required, and the disassembly and installation of formwork are avoided
2. The tensile reinforcement in the concrete floor slab can be omitted
3. Provide a flat ceiling surface for the concrete floor
4. Easy to transport, store, stack and load and unload
5. After installation, it can be used as a safe working platform
6. The corrugated room can be used for power, communication and other projects
7. Reduce the dead load of the whole structure and save the cost of the lower foundation
8. Greatly shorten the construction period, suitable for high-rise, super high-rise buildings and large multi-storey industrial plants
