Composite floor profiled steel plate

Composite floor slabs can also be called floor bearing slabs, load-bearing slabs (the most common name in the industry) floor slabs, floor slabs, steel bearing slabs, which means that the profiled steel plate is not only used as the template for the concrete floor, but also as the lower part of the floor. The force steel bars participate in the force calculation of the floor slab, and work together with the concrete to form a composite floor.

The lining board is made of profiled thin steel plates with alternating concave and convex shapes and cast-in-situ concrete is poured together and supported on steel beams to form an integral floor slab.

It is mainly composed of three parts: floor layer, composite slab and steel beam. The composite board includes concrete and steel liner. In addition, a suspended ceiling can be provided as required. The economic span of the combined floor slab is between 2 and 3m. There are many structural forms. According to the different forms of profiled steel plates, there are single-layer steel liner composite floor slabs and double-layer steel liner composite floor slabs.

It has the advantages of high strength, rigidity and durability of the reinforced concrete floor slab, and is lighter than the reinforced concrete floor slab, has the characteristics of faster construction speed and better bearing capacity. It is suitable for large space buildings and high-rise buildings, and has been widely adopted internationally. Prefabricated building
