Embodiments of the invention provide a clevis hanger system. A clevis top can include a hanging portion, a first leg with a first hole, and a second leg with a second hole. A clevis bottom can include a saddle, a third leg with a third hole, and a fourth leg with a fourth hole. To secure the clevis top to the clevis bottom and define an internal area to receive pipe, the first hole can be aligned with the third hole and the second hole can be aligned with the fourth hole, and a fastener can be received through the first hole, the second hole, the third hole, and the fourth hole. At least one of the first hole and the third hole can be surrounded by a first annular flange. At least one of the second hole and the fourth hole can be surrounded by a second annular flange.

Hanger system

A sway brace fitting clamp is used for lateral bracing of sprinkler or other types of pipe (designated the service pipe) to a structure, to prevent movement of the service pipe perpendicular to the axis of the pipe relative to the structure to which it is attached. The sway brace fitting clamp includes a U-bolt which fits around the service pipe, and a pair of hooks that are coupled to straight ends of the U-bolt, for hooking the sway brace pipe. A pair of nuts engages threaded portions of the U-bolt ends. The nuts may be tightened to pull the sway brace pipe into contact with the service pipe, firmly clamping the sway brace pipe and the service pipe together.

Lateral seismic brace

A sway brace fitting clamp is used for lateral bracing of sprinkler or other types of pipe (designated the service pipe) to a structure, to prevent movement of the service pipe perpendicular to the axis of a sway brace relative to the structure to which it is attached. The sway brace fitting clamp includes a body which fits around the service pipe, and a pair of hooks that are coupled to the body, for hooking the sway brace. The nuts may be tightened to pull the sway brace into contact with the service pipe, or otherwise firmly clamping the sway brace and the service pipe together.

A seismic sway brace includes a clamp for engaging a circular object, a sway brace member, and a pair of connecting mechanisms for coupling the circular object to the sway brace member, and for coupling the sway brace member to building structure. The sway brace member may be a sway brace pipe or rod. Each of the connecting mechanisms may include a pair of strap clamps, held together by a retainer. The strap clamps and/or the circular object clamp may include one or more longitudinal slots. The longitudinal slots enhance wrapping of the clamps that engage the sway brace member or circular object, allowing the clamps to better engage the sway brace member or circular object.

Clamp and seismic sway brace

A clamp for engaging a structure flange includes a clamp body having a slot between a pair of body sections, a spring clip on the clamp body that extends into the slot, and a pair of screws threadedly engaged with the clamp body. The spring clip holds a structure flange in place when the clamp is placed on a structure flange, with the flange in the slot. This allows the installer to tighten the screws to engage the flange, without having to simultaneously hold the clamp in place. The screws may bite into the flange, providing a more secure coupling between the clamp and the structure flange. The clamp may be used to mount a variety of objects, such as sway braces for seismic bracing.
