Core mold supporting structure of combined grid hollow floor system

The utility model relates to the technical field of concrete pouring construction, in particular to a combined grid hollow floor core mold supporting structure which comprises a frame type base, a plurality of connecting point positions are arranged on the frame type base, and detachable core mold pieces are further arranged on the frame type base and fixed through the connecting point positions. The frame type base is further fixedly connected with a poured reinforcement cage frame through the connecting point positions, the outer surface of the core mold piece is sealed, and a cavity is formed in the core mold piece. The frame type base serves as a connecting structure, the core molds are connected and prevented from floating upwards, the steel reinforcement cage frame is connected to keep the stability of the whole position, and therefore the stability of the position of the core molds in the pouring process is guaranteed, and the pouring construction quality of a hollow floor can be improved; meanwhile, t
