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.

One embodiment provides a method and apparatus for suspending air conditioning duct works from a support structure comprising unistrut type support beams which apparatus includes a plurality of support brackets arranged and configured for being slidably interlockable with the interior of the unistrut beam members. The support brackets can be slid inside the interior of the support beam until adjacent a support beam which support beam can be connected to the support bracket. In like manner additional support brackets can be inserted into the interior of the support beam members to be adjustably located next to their respective support rod. In such manner multiple support rods can be used to support a frame member even where the support rods are not symmetrically located along the length of the support beam as the support bracket can be slid/moved inside the support beam until lining up with its respective support rod. Additionally, the entire support framework can be moved relative to the plurality of support rods by sliding the framework relative to the support brackets. In such manner the location of the supporting frame member can be changed without moving the support rods.

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 beam grid is an open grid constructed from beams of a few standard sizes that are connected together by connection blocks at the intersections of the beams. The connection blocks are suspended from the structural ceiling of the room by means of an anchor and hanger and are spaced in a grid pattern to accommodate the standard size beams between adjacent connection blocks. The standard size beams are then attached to and supported between the connection blocks. The beams are connected to the connection blocks by a vertical tongue and groove connection. The tongue and groove connection provides a sliding connection that allows the beams to be easily connected and disconnected from the connection blocks without the need of tools. Consequently, the ceiling beam grid can be easily reconfigured to accommodate changes in the room below.

Disclosed is a precursor for a clip and a clip formed by the precursor. The clip is configured for mounting a furring channel to a load-bearing member and is a generally U-shaped member having a pair of sidewalls, each of which includes a pair of tabs projecting therefrom. The clip is arranged to receive the load-bearing member between its sidewalls, such that the tabs can be snap-fit under inwardly directed flanges of the furring channel. Also disclosed is a method of forming the clip from the precursor, by bending portions of the precursor to form the sidewalls of the clip, and a method for mounting a furring channel onto a load-bearing member using the clip.

A suspended ceiling arrangement for cleanroom applications includes an elongate support member and a ceiling member. The support member includes a base wall, a side wall, a flange part and a tab which together define a longitudinally extending support channel. The ceiling member includes a base wall, a side wall, a flange part and a lip part. The lip part defines a gap therein. In use, in an installed condition, the ceiling member flange part locates on top of the support member flange part, the lip part locates in the support channel and the tab locates in the gap.

A bracket assembly includes a mounting bracket including a main body and at least one support arm, the at least one support arm extending outward from the main body, the main body defining a mounting pad; and a clamp attached to the mounting pad. A sprinkler support assembly includes a ceiling system including a suspension frame and a grid support, the grid support extending laterally outward from the suspension frame; and a bracket assembly including a main body and at least one support arm, the main body attached to the grid support, the at least one support arm extending outward from the main body.

An elongated ceiling grid member and a ceiling grid assembly that includes a plurality of the elongated ceiling grid members are disclosed. The elongated ceiling grid member may include an upper portion, a lower portion and a middle portion that connects the upper portion and the lower portion. The upper portion may include a first pair of spaced and substantially parallel sidewalls having ridged interior surfaces that face each other. Similarly, the lower portion may include a second pair of spaced and substantially parallel sidewalls. Each sidewall of the second pair of sidewalls may include upper and lower ridged interior surfaces, with the distance between the upper ridged interior surfaces being different than the distance between the lower ridged interior surfaces. A plurality of the elongated grid members can be connected at their ends to form a grid of the plurality of elongated grid members.

A clip for use with a runner of a drop ceiling including a first half with a first support section comprising a first fastener aperture and a first support aperture, a first control section configured to contact the adjacent first ceiling tile, and a first retaining section below the first section comprising a first retaining tab configured to impede the travel of a first side of a bulb. The clip further includes a second half with a second support section comprising a second fastener aperture and a second support aperture, a second control section configured to contact the adjacent second ceiling tile, a second retaining section comprising a second retaining tab configured to grip a second side of the bulb, the second side opposite the first side, a fastener to couple the first half to the second half, a support element to couple the clip to an external support.
