About this detail

This electrical detail shows a multi-tier conduit trapeze suspended from overhead structural steel beams supporting a concrete deck. The assembly utilizes beam flange clamps attached to the lower flanges of structural steel beams, which connect to 0.5-inch diameter steel hanger rods threaded at each end and spaced at a maximum of 6 feet 8 inches on center. The hanger rods support stacked 2-inch by 2-inch steel channels functioning as trapeze members, such as Unistrut or an approved equal. Conduit runs are secured to the channels using typical conduit clamps. General notes instruct contractors to remove only necessary existing fireproofing for connections, restore fireproofing as required, submit all loads and support framing details to the structural engineer for review, run conduits tightly to the steel, and avoid drilling into the concrete deck.
