A suspended ceiling system for supporting panels. The system includes beams and connectors forming keyholes at their junctions. Locking keys are inserted in the keyholes to lock the connectors and beams to each other.

A ceiling system in one embodiment includes an overhead support grid comprised of a plurality of intersecting grid support members and a ceiling tile mountable to the grid. Retaining clips support the ceiling tile from the grid which may be concealed from view. The retaining clips each include a cavity that receives a grid support member and a pair of resilient mounting elements configured to lockingly engage a support member. The mounting elements are laterally movable in response to inserting the support member into the cavity of the retaining clip. In one embodiment, the movable elements include locking tabs which create a snap-fit interlock with the grid support member for securing the ceiling tile to the grid.

A structural grid support system adapted for transferring seismic loads to the vertical structural supports of a modular structure. The system includes larger and longer high load capacity main runners with mechanically fastened cross tees, which transfer seismic forces without failing. The structural grid can provide a diaphragm using mechanically fastened connections in a single horizontal plane without requiring additional overhead support from the roof deck, or requiring fewer such supports. The main runners may include additional connecting elements disposed within the usable space beneath the runner (e.g., ventral threaded receivers) for attaching deployment-specific equipment or hardware, such as network cable trays.

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

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 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.

A bracket assembly (2) for bracing a building component (3, 71) to a building structure (42), the assembly comprising a first connecting portion (4) having at least two protruding portions (6, 8) joined by a joining portion (10), each protruding portion (6, 8) connectable to a respective bracing element (44, 46) and a second connecting portion (12) having at least one depending portion (16, 18) and linked to said first connecting portion (4), said at least one depending portion (16, 18) for connection to said building component (3, 71).

An improved connector for a main tee of a suspended ceiling grid that has multiple locking elements that increase connection tensile force properties. The connector has an end tab with a forward portion bent at a lead angle and a receiving pocket with an outwardly flared entrance that, with an opposed identical connector, cooperate to provide smooth horizontal alignment. The end portion, additionally, includes an edge profile that vertically aligns itself with the receiving pocket of the opposed connector. The receiving pocket includes a spring-like resilient wall that limits the assembly force to overcome interference with projecting lock elements. The spring-like pocket wall and shape of the lock elements contribute to an audible click signaling that a connection has been completed. One of the lock elements works with a relief groove to augment self-alignment of the connectors.

Bridging connector (1) for a suspended ceiling system, and a suspended ceiling system comprising the bridging connector. The bridging connector comprises a beam connector (2) joined to a wall engagement element (3) arranged at an angle of essentially 90 degrees to the beam connector (2), the wall engagement element (3) further comprising a depressed beam engagement element portion (4).
