ABSTRACT:
An improved cellular flooring service distribution system is disclosed comprising a cellular flooring unit in which a dividing means provides a plurality of open parallel conduits in a single valley of a corrugated sheet, an overlying trench providing a plurality of transversely oriented parallel passageways which have access to said conduits and an isolating means to selectively isolate at least one conduit and passageway from the remaining conduits and passageways. Cover means and access housings are also provided. Since the above components do not require any special fabrication, they can be efficiently and cheaply mass produced, preferably from sheet metal. Service lines may be placed in open conduits and passageways prior to covering to eliminate the need for feeding the lines through enclosed cells. Since no base plate is required on the corrugated sheets, less material is used than with conventional units, the sheet can be compactly nested to facilitate shipping and handling and fire resistance is increased. Fire resistance is further increased by allowing concrete to flow beneath the trench into the undivided valleys of the sheet. Various embodiments of the general concept are disclosed.
