About this detail

An OSHA roof tie-off anchor assembly connects to wide-flange steel beams sized per plan. A galvanized four-inch diameter extra-strong pipe post rests on a one-inch thick by twelve-inch square base plate, secured with seven-sixteenths inch fillet welds. Five-sixteenths inch fillet welds connect the base assembly to the supporting steel structure. The centerline of the tie-off point, pipe post, and wide-flange beams align vertically, with a maximum height of two feet three inches. The design is based on a five thousand pound ultimate load in any direction.
