About this detail

Two fastening options secure ceiling brace wires to lightweight or normal weight concrete poured over a metal deck. Option one utilizes a twelve-gauge ceiling clip formed from a one-and-a-half by one-and-a-half-inch angle, two inches wide minimum, bent to align with the wire and anchored using a five-eighths-inch diameter expansion anchor into the deck low flute with a maximum half-inch offset. Option two incorporates a twelve-gauge angle measuring one-and-a-half by one-and-a-half inches secured with two three-eighths-inch diameter expansion anchors. Post-installed anchors must be placed no more than one inch offset from the centerline of the deck low flute and tested in accordance with ceiling note five point zero three. The specified anchor diameter may be reduced to three-eighths of an inch when project conditions meet specific design requirements for seismic acceleration, brace assembly spacing, and deck type.
