Definitions

  • the invention relates to linear metal suspended ceiling systems.
  • Linear metal ceilings typically comprise spaced parallel carriers and elongated U-shaped pans attached to and extending transversely to the carriers. It is known to provide the carriers with integral grips uniformly spaced along their lower sides for engagement with longitudinal edges of the pans.
  • the pans have been available in various widths although, sometimes, their free use has been limited by the geometry of the carrier grips. Frequently, prior linear ceiling systems have had limited resistance to seismic forces and/or wind loads.
  • the invention provides a linear metal ceiling system that affords a wide choice in pan widths, either uniform or mixed, various pan profiles, and a strong inter-engagement between a carrier and the pans.
  • the carrier has a relatively short center-to-center distance between grips so that narrow pans using adjacent grips and wide pans using spaced grips are readily accommodated.
  • the grips and panels have unique profiles that when interconnected, afford a relatively high retention force, being far greater than that available with at least some prior arrangements.
  • the grips additionally, can accommodate a wide variety of panel edge profiles so that a large selection of pan shapes and sizes is

  • a linear metal ceiling system 10 shown in FIG. 1, as carriers 11 supporting U-shaped panels 12.

  • a notch 23 is bounded by an upper horizontal edge 24, an inner vertical edge 26, an inner horizontal lower edge 27 and an outer lower inclined edge 28, the latter two elements formed by the grip 21 itself.
  • the inclined grip edge 28 lies at an angle of between 30 degrees and 60 degrees and preferably is about 45 degrees from the horizontal so that the grip edge rises in a direction towards a distal end 29.
  • a lower edge 31 of a grip 21 is preferably beveled to facilitate reception of a pan and to provide clearance for some styles of pans.
  • pans are supplied in 10 foot lengths.
  • Illustrated pans 12 can be roll formed of 22 gauge aluminum for exterior use and 24 gauge electrogalvani zed steel for interior use.
  • FIG. 4 illustrates one style of pan 12a.
  • the pan 12a has a bottom 33 with a lower face 34 and sides 36.
  • the sides 36 in their free state are cantered inwardly.
  • the pan sides 36 have inturned lips or flanges 37.
  • each flange 37 lies at an acute angle of between 30 and 60 degrees and preferably about 45 degrees with its associated side 36.
  • a pan 12a is snapped onto oppositely extending grips 21. It will be understood from FIG. 1, that all of the carriers 11 are aligned with their grips 21 located along common lines transverse to the carriers thereby enabling a carrier to be snapped onto the grips of adjacent carriers 11.
  • the style of pan 12a shown in FIGS. 4 and 5 can have a nominal width between 2 inches and 12 inches with the available widths being stepped in 2 inch increments and a nominal depth of 7/8 inch. Pans with a 4 inch width engage outlying grips 21 of two adjacent bases 22 and pans wider than 4 inches are free of attachment to bases intervening those basis to which a wider pan is attached. As shown in FIG. 5, the canted sides 36 enable the panels to butt with a closed joint at their lower faces 34.
  • the configuration of the inturned flange or hook 37 on the pan sides 36 and the upturned edges 28 on the grips 21, with their respective inclinations being complementary, i.e. in the same direction and within 20 degrees of each other has been discovered to produce an improved pan retention on a carrier 11.
  • the pans have been found to withstand loads, oriented to separate a pan 12a from the pair of grips 21 on opposite sides 16 of the carrier, of about 180 pounds of force.
  • FIGS. 6 and 7 illustrate a lap-style pan 12b.
  • the pan cross-section is asymmetric with one side having an inturned inclined flange 37 of the same or substantially the same orientation as the previously described pan 12a and on an opposite side 42 having an outwardly extending horizontal flange 43.

  • the splice plate 51 has an inverted U-shape complementary to that of the upper portion 18 of the carrier 11 so that it fits as a saddle onto the top 17 of a carrier.
  • the splice plate 51 has a center web 52 and depending sides 53 that diverge with the same angle as the upper portions 18 of the carrier 11, each side at an angle of, for example, 118 degrees from the center web.
  • the center web 52 is longer than the sides 53 of the splice plate to thereby provide cantilever tabs 54.
  • Edges 56 of the sides 53 at each end of the splice plate 51 lie on a common plane oriented at 118 degrees from the plane of the splice top or center web 52, i.e. at the same angle as the upper sides or upper portions 18 of the carrier from the carrier top web 17.
  • the splice plate sides 53 and top or center web 52 are stamped or otherwise formed with a plurality of holes 57 to receive self-drilling screws or other fasteners to attach the splice plates to the carriers 11 being joined by the splice plate. Larger holes 58 on the sides 53 are
  • the splice plate can align and join the ends of two carriers 11 where a ceiling area dimension in the direction of the carriers is greater than the standard length of a carrier.
  • the splice plate 51 can also be used to join a carrier 11 intersecting another carrier at right angles.
  • the splice plate 51 can be fixed to an end of the intersecting carrier 11, either being partially cantilevered or with the intersecting carrier being trimmed to match the geometry of the splice plate edges 56.
