Framing details illustrate floor and roof penetrations through steel deck and concrete slabs, framed with channel members and supported by wide-flange beams or joists. Openings are reinforced with two number five trim bars on each side extending two feet past the opening, alongside a quarter-inch plate connected with two three-quarter-inch or five-eighth-inch bolts. Additional support utilizes four-by-three-by-quarter-inch angle sections typically with long legs vertical, and three-quarter-inch plug welds at each deck bearing. Closure angles of sixteen-gauge or three-sixteenth-inch material seal the perimeter, while mechanical curbs anchor with half-inch expansion anchors at each corner.
