About this detail

A typical floor opening in a composite metal deck and concrete slab is framed with structural steel angles. The steel angle frame is supported by structural steel beams sized per plan, with angle spans and sizes corresponding to the included angle frame schedule ranging from L5x3x1/4 for spans up to nine feet to L6x4x5/16 for spans up to twelve feet. The metal floor deck edge is secured to the angle frames with three-sixteenths inch welds, and the metal floor deck is typically welded to the angle frame. A structural note requires contacting the structural engineer for any openings greater than forty-eight inches.
