  • Panel wall construction
    Patent number: 6189270
    Abstract: A partition wall system provides for lay-in of cables. The system includes a plurality of interconnected panel sections and a plurality of covering skins. Each panel section has a base surface and a protrusion extending from the base surface. At least one of the covering skins is attached to each of the panel sections, forming a passage between the covering skin and the base surface of the panel section allowing the cables to travel between interconnected panel sections and through each panel section, in both horizontal and vertical directions. Interconnected panel sections may include first and second sheets of material, each sheet of material providing a base surface with a plurality of protrusions extending therefrom, wherein the first sheet of material is attached to the second sheet of material so that the base surface of the first sheet of material is substantially parallel to the base surface of the second sheet of material.
