About this detail

A non-bearing steel stud wall connects to a concrete-filled steel deck overhead, accommodating vertical deflection through a one-inch gap. For walls perpendicular to the deck flutes, a sixteen-gauge deep leg slotted deflection track fastens directly to the underside using two Hilti X-U pins at twelve inches on center centered on the flute, secured with two number eight self-tapping screws at each flange slot. For walls parallel to the deck flutes, the sixteen-gauge deep leg slotted deflection track uses sixteen-gauge by four-inch straps between flutes spaced at twenty-four inches on center, fastened with two Hilti X-U pins on each side centered on the flutes. These straps are omitted where the track aligns directly centered on the flute, and two number eight self-tapping screws or Hilti X-U pins are installed at twelve inches on center centered on the flute.
