Cellular ceiling deck system with hidden hinges

摘要

A deck unit has a hinged, cover panel for use in a deck system as a ceiling. The hinge may be a continuous hinge running the length of the deck unit, preferably a continuous hinge, and extend the length and width of the deck unit including its side flanges or be recessed within it. The edge of access panel cover opposite its hinge is secured using a securing mechanism to a bracket affixed inside the deck unit. By example, a set screw is threaded through a hole in the cover panel, through a weld nut on the inside face of the cover panel and through a U-nut straddling the bracket. Accordingly from a distance, the hinge, latch and the securing mechanism are not visible to indicate that the cover can be opened to permit access to the deck system interior.
