About this detail

Double joist framing receives a blocking assembly spanning between the members with an engineered pipe and connection plate located per the roof plan above. Cold-formed steel angles measuring 2x2 are placed at each end of the blocking in sixteen total locations. The blocking assembly is secured using two rows of eight one-quarter-inch diameter screws spaced equally on each side, totaling forty-eight screws minimum centered on the blocking. Screw spacing must be confirmed with the fall protection supplier or building maintenance supplier. Metal deck is omitted for clarity.
