Reinforced concrete composite floor slab of novel steel frame house

The utility model discloses a novel reinforced concrete composite floor slab of a steel frame house. The novel reinforced concrete composite floor slab comprises an H-shaped steel beam, a prefabricated slab and a reinforcement assembly. The utility model has the beneficial effects that the rabbet groove can enhance the cooperative work capability between new and old concrete; and the prefabricated plates are processed in factories, and are quick to construct, good in reliability, low in cost and excellent in performance. When the upper concrete is poured, the bottom does not need an additional template except the template needs to be erected around the building, so that the use amount of the template is reduced; a plate bottom support does not need to be arranged, so that construction procedures are reduced, and the construction speed is increased; the steel structure design modularization, industrial production and construction standardization can be achieved easily, then the industrialization process of a s
