About this detail

This plan detail shows a structural steel column with spray-applied fireproofing enclosed by a rectangular stud-framed furring assembly. Minimum 1-5/8 inch 20 gauge metal studs are spaced at 16 inches on center with corner studs fastened together using number 8 self-tapping sheet metal screws at 12 inches on center. Metal top and bottom runner tracks are positioned at the floor and 4 inches above the finish ceiling. The framing is anchored to each side of the steel column at 4 inches above the finish ceiling using 2 by 2 by 16 gauge metal angle brackets attached to the steel column with a minimum of two 1/8 inch powder-driven fasteners having 1/2 inch embedment. The top runner track is fastened to each anchor bracket with two number 8 self-tapping sheet metal screws. The enclosure is finished with 5/8 inch gypsum board extending to 4 inches minimum above the finish ceiling, complete with metal corner beads at all exposed corners. A pipe riser and support clamp penetrating through the floor slab is located adjacent to the furred column as indicated on plumbing drawings.
