About this detail

A continuous steel riser plate assembly at the edge of a composite concrete slab over metal deck. The assembly features a continuous 12-gauge riser plate with a half-inch top return and two-inch bottom return, welded with a three-sixteenth-inch continuous fillet weld. Continuous L2x2x3/16 angles are spaced as required to plumb the structure, required over raker beams and at six-foot-zero-inch centers between, tack welded to the structure at each end. Additional support includes continuous L4x4x1/4 angles at top and bottom, rolled angles with three-sixteenth-inch continuous plates, and two number four continuous reinforcing bars with half-inch diameter by four-and-a-half-inch studs at twenty-four inches on center typically top and bottom. Five-eighth-inch puddle welds are specified at twenty-four inches on center typically at each end. Slab construction incorporates geofoam fill, a cantilevered deck over the beam, and number three continuous reinforcing bars plus number three bars at twelve inches on center with 180-degree standard hooks.
