About this detail

Criteria and framing conditions apply to unreinforced openings in a concrete slab poured over a metal floor deck, bounded by structural steel beams or joists. Cored openings ranging from six to twenty-four inches in diameter require an angle profile attached to the metal deck prior to core drilling, utilizing half-inch diameter Simpson Titen HD screws, half-inch diameter Powers wedge bolts, or half-inch diameter Hilti Kwik Bolt expansion anchors spaced at twelve inches on center with a four-inch maximum embedment. Grouped openings require minimum spacing dimensions equal to four times the largest opening diameter, or thirty-two inches minimum, failing which the group must be reinforced as a single opening. Formed openings require the metal deck to remain intact with block-outs until the concrete cures. Three full flute lengths of the metal deck must extend beyond the opening edges.
