About this detail

A fire-rated partition head assembly frames beneath a structural steel beam and concrete-filled metal deck. The structural steel beam and metal deck are fully coated with sprayed-on fireproofing. An eighteen-gauge metal Z clip is attached to the bottom flange of the structural steel beam using two minimum one-eighth-inch powder-actuated fasteners with half-inch embedment, spaced at sixteen inches on center. A twenty-gauge minimum metal top runner track features two-and-a-half-inch long slotted legs and is secured to the metal Z clips with minimum number eight sheet metal screws at sixteen inches on center. Gypsum board is attached to the metal studs on both sides of the partition, stopping a minimum of one-half inch below the metal top runner track to allow for a deflection gap. Additional continuous metal angles and galvanized expanded metal lath are integrated at the partition head with sprayed-on fireproofing overlapping the assembly. Acoustic insulation is installed within the stud cavity where scheduled, and the head of wall meets specified fire ratings and cyclical movement testing standards.
