ABSTRACT:
A metal raceway structure for use in composite, concrete-metal construction including an elongated metal deck having alternating ribs and valleys. A sheet underlies the deck in order to define a plurality of cells. The metal deck has spaced first and second ribs of generally equal height and an interposed third rib of lesser height than the first and second ribs. The ribs may have a top wall and depending sidewalls. The first and second ribs have sidewall openings facing the third rib and the third rib has at least one top wall opening. This permits electrical wires passing through each of the three cells to emerge at a single location generally within the valley between the first and second ribs. A housing member is provided in overlying relationship with respect to the third rib and has openings permitting communication between the interior of the housing and the three cells. The housing may have one or more housing extensions containing electrical receptacles which are in communication with the housing interior, but in relatively nonobstructing position with respect thereto.
