Abstract
Abstract A sway brace for fluid lines in building structures such as water supply lines in sprinkler systems, the brace including a brace element having an end adapted to be anchored to a joist or other portion of a building and having its opposite end provided with a U-bolt clamp assembly, the sway brace being disposed at an angle to the horizontal of 0* to 45* and the U-bolt encircling the water pipe to be braced, and the clamps being located on the U-bolts and having portions clampingly engaging the diagonal brace.

Claim 1
Independent Claim
187 words
A sway brace assembly for connection between a portion of a building structure and a suspended fluid supply pipe to prevent damage to the pipe from seismic disturbances wherein the improvement comprises: an elongated longitudinally rigid onepiece cylindrical combined tension and compression brace element having a relatively free end and having its opposite end flattened for convenient anchoring to a portion of a building structure at an angle to the horizontal of between 0* and 45* , a clamp comprising a pair of channel members, each having two spaced webs lying transversely of and gripping said brace element, the channel members being spaced along the brace element, and a pair of U-bolts for the pair of channel members, the ends of each U-bolt being secured to one each of the pair of channel members, the channel members engaging the brace element between opposite ends of the U-bolts, and said U-bolts being adapted to lie about and grip a fluid supply pipe and exeRt a snubbing action about the pipe by reason of the angular disposition of the brace element to increase the clamping effect of said clamp.
