About this detail

Head and base conditions for a fire-rated partition assembly anchor to a cast-in-place concrete slab and steel deck. The shaft wall utilizes C-H studs, gypsum liner panels, and a sound attenuation blanket within the cavity, framed to meet a two-hour rated basis of design per UL System No. U415. At the head, the assembly ties into the steel deck using powder-actuated drive fasteners and firestop sealant per UL System No. WW-S-0059. Mechanical fasteners secure the track at twenty-four inches on center with Hilti X-ZF low-velocity fasteners. The base track anchors directly into the concrete slab with identical powder-actuated fasteners and joint sealant.
