About this detail

The assembly features a metal longleg deflection track attached to the underside of a concrete-filled metal deck with a one-eighth to one-half inch deflection gap in the gypsum board. Rated sealant is applied across the full width of the gypsum board on both sides of the partition type. Fire safing insulation fills the metal deck flutes at the perpendicular condition, while a three-inch wide metal Z-clip matching the track gauge is spaced at twenty-four inches on center at the parallel condition. A one-inch gypsum shaftliner board baffle attaches to the runner track only with fasteners spaced at three inches on center. The top of the CH stud terminates at the runner track of the shaftwall partition.
