About this detail

A framed soffit assembly is anchored to a concrete over metal deck ceiling system. Three-by-three-inch by sixteen-gauge angles are secured into the bottom flutes of the deck using three-eighths-inch diameter by two-inch embedment Hilti KB-TZ anchors. Metal stud diagonal braces, measuring three and five-eighths inches by twenty gauge, are spaced at four feet on center in alternate directions and attached to the kickers with three number ten sheet metal screws each and one zero-point-one-seventy-seven-inch diameter power-driven fastener. The vertical framing consists of three and five-eighths-inch metal studs at twenty-four inches on center tied to a two-by-two-inch by eighteen-gauge continuous track with number ten sheet metal screws at each contact point. An acoustical tile ceiling occurs at the return, and five-eighths-inch Type X gypsum board finishes the underside of the soffit.
