Negative reinforcement self-supporting device used for reinforced concrete slab

The utility model relates to a negative reinforcement self-supporting device used for a reinforced concrete slab. The negative reinforcement self-supporting device comprises two slab negative reinforcement bodies. The same ends of the two slab negative reinforcement bodies are connected through a U-shaped support. According to the negative reinforcement self-supporting device, the self supporting capacity is achieved through the U-shaped support, the slab negative reinforcement supporting aim during construction is achieved, risks of deformation, caused by factors such as treading, of slab negative reinforcements are avoided, the project quality is easily guaranteed, the construction efficiency is easily improved, and the construction cost is easily reduced.
