An elongated sheet metal channel for transversely supporting drywall grid tees at regular intervals along the channel, the channel having a generally vertical web, and a lower flange and an upper flange, a vertical spacing between the flanges being sufficient to receive upright grid tees at the intervals, the lower flange having outer and mid-width portions lying in a generally horizontal plane at an interval when a tee is received therein, opposed formations stamped into one of the flanges at the intervals to longitudinally locate the grid tee, the upper flange at said intervals having a pocket for receiving a distorted end of a grid tee.

A ceiling system is provided for use in a building space having a plurality of walls. The ceiling system includes a grid system that extends to at least two of the plurality of walls and separates the building space into an occupiable space below the grid system and a plenum space above the grid system; and a plurality of ceiling tiles that are supported by the grid system and, with the grid system, create a barrier between the occupiable space and the plenum space, the plurality of ceiling tiles including three different polygonal non-rectangular ceiling tiles

A pre-fabricated universal operating room ceiling system including red iron steel support frames and a track assembly immediately above the ceiling in the interstitial space of the operating room for supporting medical equipment including medical gas lines and electrical and data cabling and heating, ventilation and cooling trunk lines and ducts for reducing interference with such systems when installing or moving operating room equipment.

The disclosure relates to support members for ceiling systems, such as those that can be formed into an interconnected grid to be suspended from a ceiling and support ceiling tiles. One aspect of the disclosure is a linearly-extending support member for a ceiling tile. The support member has a cross-sectional shape that includes a substantially vertical central web with a top end and a bottom end; at least one flange extending substantially horizontally from the bottom end of the web, the flange having an upper surface and a lower surface; and a bulb extending from the top end of the web, the bulb having a first side and a second side with a cavity therebetween, the bulb having an upper portion and a lower portion adjacent the top end of the web, wherein the entire lower portion of the bulb is narrower than the upper portion of the bulb and wider than the central web, the bulb comprising a series of spaced apertures formed therein through both the first side and the second side of the bulb, each aperture being disposed at least partially in the lower portion of the bulb, each aperture having an upper portion and a lower portion, wherein the upper portion of the aperture is rounded.

A hanger and a ceiling suspension system incorporating the hanger, for suspending a suspension rail from a ceiling are provided, where the suspension rail is configured to support an object. The hanger includes a first suspension member and a second suspension member positioned adjacent to one another. The first and second suspension members each have an upper portion, a lower portion, and a coupling component situated between the upper and lower portions. The upper portions are configured to be releasably suspended from the ceiling. The lower portions are configured to releasably engage the suspension rail. The coupling components are engageable to form a hinge connection between the first and second suspension members. Separation of the upper portions from one another biases the lower portions towards one another to releasably engage the suspension rail between the suspension members.

A ceiling system is provided for use in a building space having a plurality of walls. The ceiling system includes a grid system that extends to at least two of the plurality of walls and separates the building space into an occupiable space below the grid system and a plenum space above the grid system; and a plurality of ceiling tiles that are supported by the grid system and, with the grid system, create a barrier between the occupiable space and the plenum space, the plurality of ceiling tiles including three different polygonal non-rectangular ceiling tiles.

A faceted architectural fixture is provided that include one or more folded elongated strips, each providing a series of alternating faceted surfaces.

A method for mounting a support assembly to a ceiling support structure is disclosed. In example aspects, the method can comprise providing the support assembly, the support assembly comprising a bracket assembly, the bracket assembly comprising a first plate, a second plate, and a seating frame; positioning the seating frame in an open position; positioning a portion of the ceiling support structure within a space defined between the first and second plates; and securing the bracket assembly to the ceiling support structure.

The disclosure relates to support members for ceiling systems, such as those that can be formed into an interconnected grid to be suspended from a ceiling and support ceiling tiles. One aspect of the disclosure is a linearly-extending support member for a ceiling tile. The support member has a cross-sectional shape that includes a substantially vertical central web with a top end and a bottom end; at least one flange extending substantially horizontally from the bottom end of the web, the flange having an upper surface and a lower surface; and a bulb extending from the top end of the web, the bulb having a first side and a second side with a cavity therebetween, the bulb having an upper portion and a lower portion adjacent the top end of the web, wherein the entire lower portion of the bulb is narrower than the upper portion of the bulb and wider than the central web, the bulb comprising a series of spaced apertures formed therein through both the first side and the second side of the bulb, each aperture being disposed at least partially in the lower portion of the bulb, each aperture having an upper portion and a lower portion, wherein the upper portion of the aperture is rounded.

A ceiling suspension system is disclosed and includes a plurality of grid members configured to form a grid for the ceiling suspension system, each grid member comprising a bulb, a web and a flange. The system also includes a plurality of wall support brackets configured to mount the grid to walls in a structure. Each wall support bracket comprises a vertical back, a lower flange at a lower end of the vertical back, and an upper flange at an upper end of the vertical back. Further, the upper flange is generally V-shaped when viewed longitudinally and each wall support bracket only one tab in the lower flange for each grid member. Moreover, the only one tab is configured to engage and retain the flange of a respective grid member, such that the respective grid member rests on the lower flange.
