What are the types of cast-in-situ reinforced concrete floor slabs?1.Slab floorsSlab slabs are one of the most common types of concrete floors, characterized by their small spans and thin thickness, and are often used for non-load-bearing walls or secondary load-bearing structures in multi-storey or high-rise buildings. The structure of the slab floor slab is relatively simple, made of steel and concrete, and has the advantages of convenient construction, light weight and high stiffness. However, due to its small spans, more complex structural forms are required for large-space buildings.
2.Beam-slab floor slabsBeam-slab floors are composed of reinforced concrete beams and slabs, which have a large span and are suitable for a variety of different building types, such as shopping malls, warehouses, etc. The advantages of beam-slab floor slabs are their strong bearing capacity, high rigidity, good integrity, and the size and shape of the beams can also be adjusted as needed. However, compared with slab floors, the construction of beam-slab slabs is relatively complex and has a larger dead weight.
3.Beamless floor slabsBeamless floors are a special type of concrete floor slab, characterized by the absence of exposed beams, consisting of a combination of dark beams and slabs. The advantage of this kind of floor slab is that it is open and beautiful, and is suitable for buildings with high space requirements, such as gymnasiums, performance halls, etc. The structure of beamless floor slabs is relatively complex, requiring the use of special formwork and supporting structures, and the construction is difficult. 
4.Profiled steel plate composite floor slab Profiled steel plate composite floor slab is a new type of concrete floor slab, which is composed of a combination of profiled steel plate and concrete. The advantages of this kind of floor slab are that its construction speed is fast, the bearing capacity is strong, and the rigidity is large, which is suitable for all kinds of buildings that need to be constructed quickly. At the same time, the weight of the profiled steel plate composite floor slab is lighter, which can reduce the overall weight and ** effect of the building. However, the cost of such floor slabs is high and requires the use of specialized profiled steel plates and construction techniques.
