Disclosed is a supporting element for a suspended ceiling system, wherein the suspended ceiling system includes hanging wires coupled to a structural ceiling; includes T-bars supported by the hanging wires; and includes a plurality of ceiling panels arranged in an array of cells defined by the T-bars; wherein flat end-portions of the T-bars defines a general ceiling plane for the plurality of ceiling panels; wherein the supporting element, when in operation, supports a given ceiling panel of the plurality of ceiling panels in at least one of higher than the general ceiling plane, lower than the general ceiling plane, or at a tilted angle relative to the general ceiling plane, wherein the given ceiling panel, of the plurality of ceiling panels, supported by the supporting element provides a three-dimensional appearance to the suspended ceiling system.

A system for mounting plurality of panels includes a carrier part for receiving and supporting the panels at intervals along the length, and a locking strip. The carrier part and the locking strip can be mounted to each other to couple the locking strip relative to the carrier part in a locked position with an elongate edge of the locking strip engaging with the panels.

A ceiling module and method of constructing the same, the ceiling module mountable on a suspended ceiling grid structure and including a plurality of elongate blade members having opposing faces, at least a part of each face of at least two blade members being substantially mutually opposed, at least one elongate cross member extending at least between at least two blade members such that the plurality of blade members are connected to form an arrangement; and at least one support member, releasably engageable with the suspended grid ceiling structure and associated with at least one of the blade members to support the plurality of blade members from the suspended ceiling grid structure.

A structure-lining apparatus comprising a plurality of transversely and longitudinally extending panels connectable to a structure and connectable edge-to-edge via complementary connector components on their longitudinally extending edges. Each panel comprises transversely extending edges generally orthogonal to their longitudinally extending edges. Each panel comprises first and second complementary connector components on first and second longitudinally extending edges thereof. The apparatus comprises at least one edge-to-edge connection between a first connector component of a first panel and a second connector component of a second panel wherein a primary male connector component of the second connector component of the second panel is extended into a primary female connector component of the first connector component of the first panel and a secondary male connector component of the first connector component of the first panel is extended into a secondary female connector component of the second connector component of the second panel.

A method, system, and tool are disclosed for installation of ceiling tiles in an improved mounting hook assembly to form a concealed grid system The system includes elements for attaching the mounting hook assembly to the tile; rotating a load bearing lever member; rotating a positioning lever member to position the load bearing member on a flange of a T grid bar; and fixing the tile below the T grid at a distance that is greater than the thickness of the tile so that when the tile is lifted up, the load bearing lever is returned to a position above the flange level of the T grid and any tile can be removed or installed in a totally concealed grid system without dislocating tiles already laid. A tool is used to engage and disengage the tiles.

A building panel system is provided that includes a perimeter frame; a main beam attached to the perimeter frame; a carrier attached to the main beam, the carrier having a plurality of identical hook members, each of the hook members having a protruding hooking portion on only a first side of the hook member, and a non-hooking portion on a second side of the hook member, the second side being opposite the first side; and a plurality of panels removably attached to the carrier, each of the panels being attached to the carrier by engaging one of the hooking portions.

An edgelit multifunctional lighting assembly is configured as a cross tee within a suspended ceiling system and supports at least one ceiling panel and is configurable to produce symmetric and asymmetric targeted light distributions for narrow and wide angle illumination applications.

A ceiling grid lighting assembly for use in suspended ceiling systems is provided with multiple linear lighting modules in parallel arrangement. End plates are used to connect, support, and enclose longitudinal ends of the elongate body of each linear lighting modules while simultaneously functioning as reflective faces for optical cavities. A configured gap spacing between individual linear lighting modules can be used to house and support components such as additional light sources, acoustic or decorative panels, HVAC components, or power systems, controls or sensors. The end plate can also be configured to allow a T-bar to be placed in the configured gap spacing thereby enabling the mounting of the assembly in-line upon the longitudinal axis of a ceiling grid T-bar. Embodiments of linear lighting modules are presented comprising LED light sources, light guides and diffusers housed within the elongate body. The light guides may be edgelit from one or two sides and aligned horizontally or tilted relative to the ceiling grid plane.

A building panel system is provided that includes a perimeter frame; a main beam attached to the perimeter frame; a carrier attached to the main beam, the carrier having a plurality of identical hook members, each of the hook members having a protruding hooking portion on only a first side of the hook member, and a non-hooking portion on a second side of the hook member, the second side being opposite the first side; and a plurality of panels removably attached to the carrier, each of the panels being attached to the carrier by engaging one of the hooking portions.

A ceiling system for a clean room, a clean room ceiling and a method for constructing a ceiling for a clean room are provided. T-shaped beams support the ceiling from a building structure. Channels support composite panels on the bottom side of the T-shaped beams. Each of the channels is attached to the top side of a composite panel and each engages a first or second leg of a T-shaped beam. The channels may be Z-channels.
