The utility model relates to a tiled network floor. The tiled network floor is provided with unit floor blocks, wire grooves and wire groove cover plates. Each unit floor block is formed by an upper plate and a lower plate in spot welding and powder coating modes. The profile of each upper plate is in a convex shape, and grooves are pressed around the upper plates. The profile of each wire groove is in an inverted omega shape, and the two side edges of each wire groove are hung on the corresponding grooves. The wire groove cover plates cover the wire grooves. The two side edges of each wire groove are each provided with a locating device, and locating grooves corresponding to the locating devices are formed in the lower surfaces of the wire groove cover plates. According to the tiled network floor, the wire groove cover plates can be located through the locating devices, the wire groove cover plates can be prevented from being shifted, meanwhile, the fixation to the wire groove cover plates by rivets or screws is reduced, and thus the wire groove cover plates can be opened directly for detecting when winding displacement and wiring or maintenance overhauling is conducted.
