Electrical floor hatch and wiring system for a concrete floor structure

Abstract

An electrical wiring distribution system adapted for securement with a metal floor structure is provided. The system includes a hatch structure secured to a cellular floor structure. The hatch structure has a housing having an interior portion therewithin and an open bottom end. The housing has opposed sidewalls disposed transverse to the enclosed metal cells and bottom portions extending downwardly in close adjacency with channelways of the floor structure to prevent ingress of concrete into the interior portion. The housing has a pair of side portions having edges forming an access opening in communication with the interior portion of the housing. A divider structure is provided in the interior portion of the housing for dividing the interior portion of the housing into at least a pair of sections. The housing has an upper flange defining a top access opening. A fire retardant member is provided which is sized and adapted for extending about the upper flange between the housing and a ring assembly removably secured to the housing. The ring assembly being adapted to receive a cover plate removably secured thereto. A generally rectangular shaped duct structure defines a raceway extending therethrough. The raceway has an inlet opening in communication with the access opening of the housing. Main power and communication lines extending through the floor structure are accessible through the hatch structure for extension in the duct structure.
