About this detail

This wall section details a cold-formed metal stud partition intersecting a concrete slab over a metal deck at both the head and the sill. The head condition utilizes a deflection track with two-and-a-half-inch legs, secured to the concrete deck using powder-actuated Hilti X-U fasteners spaced at twenty-four inches on center with a one-and-a-quarter-inch minimum embedment per ESR-2269. The deflection track gauge matches the wall stud gauge, and studs are secured to the track with number ten sheet metal screws on both sides while keeping gypsum board stopped short of the track. At the sill, a concrete curb receives a minimum twenty gauge continuous metal runner and metal stud framing, with gypsum board on one side and base trim where required over a sealant bead. Additional provisions include a cripple stud at four feet maximum on center for single-sided sheathed framed walls, a bridging stud at four feet maximum on center, and ceramic tile where indicated.
