About this detail

Concrete over metal floor deck spans across steel beams and W8x10 minimum cross beams framing a floor opening. A three-sixteenths inch weld secures the floor deck to typical L3x3x1/4 structural steel angles. Closure plates detail the edge of the opening where steel shims may be used when beams are lower than joists, with shims consisting of sections of angle, channel, or steel tube. Deck bearing angles are omitted if the deck is cut tight around columns, and similar conditions apply at building perimeters and corners.
