About this detail

A concrete topping over metal floor deck terminates at a floor opening framed by W8x10 cross beams connected to supporting steel beams or girders. A typical L3x3x1/4 steel angle supports the metal deck edge, secured with three-sixteenths fillet welds. Steel shims consisting of angle, channel, or tube sections are used where beams are lower than joists. A closure plate detail completes the deck termination at the opening edge, and the deck bearing angle is omitted if the deck is cut tight around columns.
