Hanging load support

摘要

A system for supporting loads from a support structure. The load is supported with threaded rods that are connected from above and below a suspended ceiling of roll-formed sheet metal beams. Clips on the rods connected to the beams pass the load through the suspended ceiling grid without bending or twisting the grid, so that the suspended ceiling remains level, balanced, and intact above the suspended load.

主权项

1. A suspended ceiling comprising:
a grid of beams below a structural support, each of the beams being made of roll-formed sheet metal and having an inverted T cross section having a vertical web having a top and a bottom, horizontal flanges-extending opposite from one another at the bottom of the vertical web, and at least one bulb at the top of the vertical web; a first upper threaded hang rod above the grid of beams secured into the structural support and secured to the grid of beams by a first hang clip comprising:
a lower portion including a cutout which straddles a main beam of the grid of beams at the intersection of the main beam and a pair of opposing cross beams of the grid of beams;a first wing attached to a bottom of the lower portion on a first side of the main beam, the first wing secured to a first cross beam of the pair of opposing cross beams by a first rivet;a second wing attached to a bottom of the lower portion on a second side of the main beam opposite the first side, the second wing secured to a second cross beam of the pair of opposing cross beams by a second rivet; anda top portion attached to the lower portion, the upper threaded hang rod being inserted into the top portion and secured to the top portion by a first nut and a second nut, wherein the top portion has an offset so that the upper threaded hang rod is in-line with the cutout, thereby preventing torsion stresses on the main beam; a lower threaded load rod below the grid of beams, the lower threaded load rod secured to the grid of beams by a load clip; and a load below the grid of beams supported by the lower threaded load rod; wherein the lower threaded load rod and the upper threaded hang rod enable tensile forces applied to the grid of beams by the load to pass through the grid of beams to the structural support without creating torsion or twisting forces in the grid of beams.
