Abstract
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.
Claims19
A method of seismic bracing, the method comprising:
- placing a clamp around a circular object to be braced;
- and
- using one or more additional clamps to secure the clamp around the circular object to a sway bracing member;
- wherein the clamp for the circular object includes:
- a first bar portion having a first curved central section, and a pair of first extensions extending from opposite ends of the first curved central section;
- a second bar portion having a second curved central section, and a pair of second extensions extending from opposite ends of the second curved central section;
- and
- a pair of fasteners joining the bar portions together;
- wherein the first bar portion has a pair of holes in respective of the first extensions;
- wherein the second bar portion has a pair of holes in respective of the second extensions;
- and
- wherein at least one of the holes in the second extensions is an open hole;
- wherein the placing includes:
- placing respective curved central sections of first and second bar portions on opposite sides of the circular object;
- and
- coupling the bar portions together, with the object to be clamped between the curved central sections, wherein the coupling includes passing a shaft of a fastener that is coupled to one of the extensions of the first bar portion, through a slot and into an open hole in one of the extensions in the second bar portion.
A seismic sway brace comprising:
- a circular object clamp;
- a sway brace member;
- and
- one or more additional clamps for coupling the sway brace member to the circular object clamp, and for coupling the sway brace member to building structure;
- wherein the circular object clamp includes:
- a first bar portion having a first curved central section, and a pair of first extensions extending from opposite ends of the first curved central section;
- a second bar portion having a second curved central section, and a pair of second extensions extending from opposite ends of the second curved central section;
- and
- a pair of fasteners joining the bar portions together
- wherein the first curved central section has a longitudinal slot therein extending from in a direction from one of the opposite ends of the first curved central section to the other of the opposite ends of the first curved central section.
A seismic sway brace comprising:
- a circular object clamp;
- a sway brace member;
- and
- one or more additional clamps for coupling the sway brace member to the circular object clamp, and for coupling the sway brace member to building structure;
- wherein the circular object clamp includes:
- a first bar portion having a first curved central section, and a pair of first extensions extending from opposite ends of the first curved central section;
- a second bar portion having a second curved central section, and a pair of second extensions extending from opposite ends of the second curved central section;
- and
- a pair of fasteners joining the bar portions together;
- wherein the first bar portion has a pair of holes in respective of the first extensions;
- wherein the second bar portion has a pair of holes in respective of the second extensions;
- and
- wherein at least one of the holes in the second extensions is an open hole.
