About this detail

A closure plate assembly supports a concrete-over-metal-floor-deck slab edge overhang of twelve inches or less. A bent closure plate with headed deformed bar anchors at twenty-four inches on center maintains a one-inch concrete cover at the edge. The steel beam supports an outrigger and a diagonal kicker angle of three-by-three-by-one-quarter inches, with optional substitution for a heavier angle connected to the nearest beam. A continuous number five reinforcing bar runs along the edge, providing three-quarters of an inch minimum gap at the steel stud bypass framing. Fillet welds of three-sixteenths inch secure the structural steel connections, with optional two three-quarter-inch A325 bolts permitted in lieu of field welds.
