ABSTRACT:
A floor structure electrical junction apparatus mounted within a structural slab for providing electrical power connections and communication connections. A load bearing chassis has one or more generally rectangular apertures and a top portion having a vertically recessed lip portion circumscribing inwardly facing peripheral edges of each aperture. One or more receptacle modules are constructed to fit within the apertures, where each of the receptacle modules provides a plurality of electrical power or communication connectors. Two or more upstanding support members depend from the top portion where the support members rest upon a bottom portion of the structural slab. The support members have flanges horizontally projecting toward a central portion of the aperture, the flanges being disposed below the recessed lip portion for supporting a bottom portion of the receptacle module. A raceway portion is defined between the bottom portion of the receptacle module and the bottom of the structural slab to provide under-floor electrical wiring access to the receptacle module. A load bearing cover plate covers the top portion of the chassis and communicates with the recessed lip portion along its peripheral edges such that the cover plate is flush with the top portion of the chassis and flush with a top surface of the structural slab.
