The utility model relates to a network floor which is provided with floor bodies and supports. The supports are fixed to the ground through fasteners, and the floor bodies are laid on the supports through corner lock holes. Each floor body comprises a face plate and a bottom plate which are formed in a stretching mode. Downwards-extending hemispherical grooves are evenly distributed in the bottom plates, and the sections of the edges of the bottom plates are in a circular arc transition step shape. The face plates and the bottom plates are fixed through spot welding, and cavities formed between the face plates and the bottom plates are filled with foamed cement packing layers. The network floor is simple in structural design and convenient to lay, the strength is improved through the hemispherical grooves and the step shape of the edges, it is avoided that the thickness is increased for ensuring the strength, and materials are saved. The hardness of the whole floor bodies is increased by injecting the foamed cement packing layers, and the network floor is suitable for office buildings, intelligent office environments and other sites needing to be erected.
