Abstract: A method of using a hanger for supporting a load from an underside of a metal decking is described. The metal decking has a trough with a first groove opposing a second groove, and the hanger includes a flexible body which has an unflexed length that is greater than the groove spacing and is adapted to accept a load from a rod, cable, or wire. The method includes inserting the load support assembly through the aperture; contacting the first end of the body with the first groove of the metal decking; flexing the body to decrease the distance between the first end and the second end to a distance equal to or less than the groove spacing; and contacting the second end of the flexible body with the second groove of the metal decking. The body supports the load support assembly between the first groove and the second groove, and such that the load support assembly is movable relative to the flexible body.

Abstract: A hanger for suspending a load from a metal decking is described. A first hanger includes a body having ends that may be placed between opposing metal decking grooves and a separate assembly placed through an aperture in the body and adapted to support a load. The hanger thus permits the load to move side-to-side in the hanger, thus lessening the impact of seismic events on the hanger. A second hanger attaches two bodies, each having ends that may be placed between opposing metal decking grooves and a separate assembly placed through an aperture in the body used to attach the bodies to a strut channel. An additional assembly attached to strut channel is adapted to support a load. A hanger and method are also presented for preventing damage to concrete-filled metal decking hangers resulting from a seismic event.

Abstract: A hanger assembly and method of hanging conduits in buildings is described which protects the structure of the building from damage during a seismic event. The hanger assembly includes a frangible element which is calibrated to break when subjected to some higher than normal tensile load resulting from rapid acceleration of the conduit. Thus, for example, in the event of an earthquake, the hanger will fail before damage is done to the concrete to which the anchor is attached.

Abstract: A hanger and method of attaching a hanger to a deck is described. The method includes attaching the hanger parallel to the ground by attaching them to opposing surfaces of a corrugation of the deck. Certain methods include expanding the length of the hanger to place it in compression. Other methods include flexing the hanger to place it in compression. The method is particularly useful in retrofitting as it generates very little noise and vibration in a structure.

Abstract: An apparatus and method for the seismic stabilization of loads supported by hanger rods are presented. The apparatus includes a compression member that is placed in parallel to a hanger rod and which spans, or substantially spans, the distance from the load, which may be a conduit, and the supporting structure. This apparatus may be retrofit onto existing load-bearing hanger rods, or may be included at the time of installation of the conduit. Methods of installation are described that allow for providing additional structural integrity without disassembly of existing supports.

Abstract: A clamp is disclosed along with method of using the clamp attach or more or more strut channels to another element, which may be a flange, such as the flange of an I-beam or another strut. The clamp has an opening to accept the strut channel between a pair of sides and against the bottom of the clamp, and a pair of clamp surfaces for contacting the other element. A threaded element is provided for forcing the strut channels against the other element. A method for using the clamp allows the clamp to be placed anywhere on the strut channel and allow an installer to tighten the clamp from either above or below the clamp.

Abstract: Stiffener apparatus for stabilizing a hanger rod includes a clamp having a mechanical fastener extending through openings formed in spaced clamp segments. The clamp is constructed of deformable material so that the clamp segments bend into engagement with the hanger rod to urge the hanger rod toward an elongated stiffener member positioned between a closed end of the clamp and the hanger rod when the mechanical fastener is tightened.

Abstract: A bracket connects a structural member to a structural element to stabilize the structural member against movement. The bracket includes connector portions for connecting the bracket to tensioned stabilizing cables or other structural stabilizing elements and one or more bearing elements which bear against the structural member to prevent relative rotational movement between the bracket and the structural member.

Abstract: A hanger rod stiffener includes a clamp having two straight, double-ended, spaced, parallel clamp segments and a third clamp segment extending between them. The clamp is positioned over a stiffener member and a hanger rod and the third clamp segment is disposed at an angle to bias the hanger rod to a predetermined position within the clamp when the stiffener member and clamp are brought together.

Abstract: A brace for retaining a rod at a fixed location relative to building structure. The brace includes two brace members in face-to-face engagement to define a rod receiving opening with slots formed in the brace members. The brace members are connected together by an integral rigid attachment element at a location spaced from the rod receiving opening and resisting relative movement between the brace members.

Abstract: Stiffener apparatus for stabilizing a hanger rod includes a clamp having a mechanical fastener extending through openings formed in spaced clamp segments. The clamp is constructed of deformable material so that the clamp segments bend into engaged with a stiffener member extending along the hanger rod. Tightening of the mechanical fastener urges the stiffener member into tight engagement with the hanger rod.

Abstract: Support apparatus for supporting one or more objects from a concrete structure includes an insert for embedment in the concrete structure and a hanger rod connected to, extending downwardly from and supported by the insert. The hanger rod includes an end that extends over a top member of the insert and the insert and hanger rod include structure cooperating to maintain the hanger rod at a desired location relative to the insert.

Abstract: An attachment member is connected to a channel member to stabilize and restrict movement of the channel member when the channel member is suspended. The attachment member includes a plurality of attachment member plates, at least some of the attachment member plates being angularly disposed relative to one another. One of the plates engages a leg of the channel member and another of the plates projects outwardly from the channel member for attaching stabilizing structure.

Abstract: Hanger apparatus includes a, hanger member and spaced projections attached to a base of the hanger member. The hanger member can be oriented to allow for support by a hanger rod, in which position the projections engage a conduit, or oriented to support a channel member by the projections.

Abstract: A hanger assembly for hanging elongated members from a support includes two hangers releasably connected by a connector to the support, one of the hangers being positioned in the interior of the other hanger. The connector includes side walls which cooperate with shoulder elements connected to the hangers to maintain proper positioning of the hangers.
