A concrete curb supported on a concrete slab-on-deck assembly carries a cold-formed metal stud wall. The concrete curb features continuous reinforcing steel and transverse dowels tied into the slab reinforcement. For interior wall conditions, the track is anchored with three-eighths-inch diameter Hilti Kwik Hus-Ez screw anchors with two-and-a-half-inch minimum embedment at twenty-four inches on center. Exterior wall anchorage requires specific detailing per architectural drawings. The curb width ranges from four inches minimum for interior walls to six inches minimum for exterior walls, with an eight-inch maximum width requiring two rows of reinforcing.
