Abstract
An improved high strength cellular metal floor raceway system for distribution of service lines and the like is disclosed. Deck members are provided on upper and lower levels and present at least one uninterrupted deck conduit extending substantially horizontally on both deck levels. The deck conduit extends transversely with respect to one or more longitudinally extending beams which support the deck members. A feeder member having at least one uninterrupted feeder conduit therein extending substantially parallel with respect to the supporting beams is at least partially recessed within the upper deck level above the lower deck level. An upper surface of the feeder member is preferably provided on substantially the same vertical level as an upper surface of the upper deck level. A layer of concrete is provided over substantially the entire surface area of the conduit system. The combined or composite action of the beams, deck members and overlying concrete slab provides greater strength than prior art structures. The upper finished concrete surface provides an unobstructed, unrestricted fully utilized floor surface.
