About this detail

Fire-rated shaft wall conditions feature head connections to structural steel beams and concrete decks, alongside stair shaft framing configurations. Shaft wall studs attach using two number eight self-tapping metal screws to hanging studs at four feet on center typical unless otherwise noted. 14-gauge plates bridge the deck flutes, secured to the concrete deck with four 3/8-inch diameter Hilti Kwik Bolt TZ anchors with a minimum two-inch embedment at two feet on center and two inches from ends. Angles measuring 2 inches by 2 inches by 1 foot by 16 gauge secure to the plates using two number eight screws. The assembly incorporates UL-2079 test standards including UL HW-D-0043, UL HW-D-0136, UL HW-D-0210, and UL HW-D-0252, with gypsum board edges finished and joints filled per UL WW-D-0045.
