An elevated cable trough floor solution for office buildings, characterized in that it includes a number of movable cable trough floors assembled alternately with the floor bodies, and the movable cable trough floors are hollow wiring floors. This type of floor can reasonably configure movable cable trough floors that can be wired between the floor bodies, integrating elevated floors and cable troughs. It can not only reduce the height of the installed floor and improve the utilization rate of the floor space, but also further enhance the function of the elevated floor. Various lines can be arranged to reach any location in the office through cable troughs, making wiring more flexible. At the same time, strong and weak electricity can be separated and isolated according to national standards, and the wiring troughs can be distinguished by color or marking, which is convenient for secondary integrated wiring and inspection and maintenance in the future. In addition, when wiring, you only need to open the cable trough cover of the floor to wire and inspect, saving time, effort and cost.
