About this detail

A fire suppression pipe is anchored to a concrete deck using a three-eighths-inch all-thread rod and a Tolco Figure 200 hanger ring. Lateral seismic restraint is provided by a three-eighths-inch all-thread rod splay wire with a maximum length of two feet four inches, connected to the lower deck flute with a one-inch-wide by two-inch-long twelve-gauge minimum steel strap and Hilti KB-TZ2 anchor. A Tolco Figure 75 swivel attachment connects the splay rod to the strap with a maximum one-inch offset from the centerline of the flute, while the lower end secures to the pipe using a Tolco Figure 25 or tight all-thread rod connection. Bracing wires of number twelve gauge with a four-hundred-forty-pound capacity feature four tight turns within one and a half inches of both ends and two tight turns around the pipe.
