About this detail

A depressed concrete topping is cast over a steel deck supporting a floor drain and integrating with a structural steel beam below. Three-quarter-inch diameter by four-and-one-half-inch headed shear studs are welded through the steel deck at the slab depression, with short studs restricted from extending beyond the edge of the depression. Lower layer reinforcing matches typical slab reinforcement per plan and extends two feet six inches past the edge of the depression on all sides. Additional slab bars extend two feet zero inches past the depression in each direction on each side. A sloped concrete topping drains toward the drain body as coordinated with mechanical and architectural drawings.
