Multi-ribbed beam hollow floor technology is an innovative achievement of great significance in the field of architecture. It integrates the advantages of prefabrication and cast-in-place technology, and has the floor form of spatial grid skeleton, beam-slab integration, flat bottom, I-section and large flange (flange thickness is different in different parts). The hollow floor of multi-ribbed beam is composed of prefabricated laminated plate, combined mould and post-pouring multi-ribbed beam, which are connected into a whole. Its basic stress unit is I-shaped rib beam with large flange; Composite slab is the basic condition for the realization of new technology, and it is a hollow closed box made of high-strength composite concrete. The four side walls of the box play the role of ribbed beam formwork, and the upper cover and the lower bottom participate in the overall stress of the structure. In different positions of the floor slab, the reinforcement and wall thickness of the composite slab are also different, and the upper cover and lower bottom in different positions are also stressed differently. Scope of application: Multi-ribbed hollow floor technology is suitable for all kinds of multi-storey and high-rise buildings, such as shopping malls, multi-storey warehouses, multi-storey factories, large conference halls, libraries, underground garages, multi-storey garages, teaching buildings, TV studios, office buildings and small gymnasiums.
