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.
Claims16
A hanger for supporting a load from the underside of a metal decking, where the metal decking has a first groove and a second groove, and where the first groove is opposite to and parallel to the second groove with a groove spacing, said hanger comprising:
- a body having a first end and a second end separated by a length greater than the groove spacing, where said body includes a
- a first body end,
- a second body end spaced by the length from the first body end,
- a top surface extending between the first body end and the second body end,
- a bottom surface opposite the top surface, and
- an aperture through the body from the top surface to the bottom surface;
- and
- a load support assembly removably supported by and movable relative to the body, where the load support assembly includes
- a first portion sized to fit through the aperture and having a first end, and
- a second portion at least partially sized to not fit through the aperture,
- where the load support assembly extends through the aperture with the first end below the bottom surface and the second portion adjacent the top surface and is adapted to support the load,
- where the body is flexible, and when the body is placed with the first end in the first groove and the second end in the second groove, and a load is provided to the load assembly, the load is suspended below the metal decking.
