Method for manufacturing oversized prefabricated composite floor slab containing multiple built-in fittings

The invention discloses a method for manufacturing an oversized prefabricated composite floor slab containing multiple built-in fittings, and belongs to the technical field of manufacturing of residential prefabricated parts. The method comprises the steps that firstly, a mold cleaning machine is used for cleaning a bench formwork, a data line-marking machine is used for inputting the model, the specification and the size of the composite floor slab into a computer, a side formwork is mounted, and mold releasing agents are sprayed; secondly, steel bars and the built-in fittings are mounted, and then concrete pouring and vibrating are conducted; finally, maintenance, mold releasing and hoisting are conducted, and therefore manufacturing of the oversized prefabricated composite floor slab containing the multiple built-in fittings is completed. According to the method, the oversized prefabricated composite floor slab is manufactured in a factory adopting semi-automatic flow line production, the built-in fittings are mounted in the floor slab, labor cost is lowered, the production efficiency of the floor slab is improved, and the high quality of the floor slab is guaranteed.
