The disclosure relates to a method of preparing an installation, to a method of installation of a false ceiling or wall, to a tile for use in such a false ceiling or wall and to a false ceiling or false wall.

The method of preparing an installation comprises: calculating (202) format, position and orientation for each individual tile in the suspended ceiling or wall, associating (202; 206) each individual tile with a unique tile identity, producing (300) the individual tiles according to the calculated format, providing (301) respective tile with the tile identity of respective tile, providing (302) a representation of the suspended ceiling or wall including an association of the position of respective tile with respective tile identity.

A ceiling framework includes main beams and cross beams, which are connected to one another and transversally to one another by connectors borne by one type of beams among the main beams and the cross beams, and engaged in apertures made in the other type of beams among the main beams and the cross beams, so as to receive tiles. For each beam having the apertures, the apertures are marked with symbols on each face of the beam, the symbols marked on each face being repeated sequentially over the length of the beam, the period of the sequences of symbols on each face being equal to a given tile size. The marking is the same on either face of the beam, starting with the same symbol on each left-hand or right-hand end for each observed face.

A suspension system for a suspended ceiling includes, in an installed state, a primary profile which substantially extends in a first horizontal direction, one or more suspension elements for the suspension of the primary profile, a secondary profile which extends in a substantially second horizontal direction and which is configured to support ceiling plates, a coupling bracket for the coupling of the primary profile to the secondary profile. The coupling bracket includes a main body which couples to the primary profile; two coupling legs which extend from the main body and which connect to the secondary profile; and a positioning element which is configured to work with the primary profile to position the coupling bracket in relation to the primary profile.

A ceiling system in one embodiment includes a support grid including intersecting grid support members and grid openings formed between the grid support members. A vertical baffle is positioned in a grid opening and is attached to the support grid. The baffle includes opposing front and rear faces extending between opposing lateral sides of the baffle. First and second mounting grooves formed in the baffle engage and support the baffle from the grid. In one embodiment, one of the mounting grooves is disposed in each lateral side to support the baffle from opposite sides. The baffle may further include a third mounting groove formed in the rear face which engages the support grid to help align and squarely register the baffle with respect to the grid for clean linear visuals. In one embodiment, the grid support members may have a standard T-shaped cross section.

Disclosed is a main carrier mounting mechanism having a ceiling lightweight steel structure, which includes: an upper horizontal portion mounted on a rod hanger; having an upper end integrally coupled to one end of the upper horizontal portion and a lower end extending downward; a lower panel having one end integrally coupled to the lower end of the main standing portion and having an opposite end extending parallel to the upper horizontal portion; and a lower standing portion having a lower end integrally coupled to the opposite end of the lower panel, and an upper end extending toward an opposite end of the upper horizontal portion, and further includes a main carrier separation prevention fastener having one end integrally coupled to the upper end of the lower standing portion and an opposite end extending toward the opposite end of the upper horizontal portion and extending toward the main standing portion.

A ceiling system for under-deck installation includes ceiling panels and retaining clips. Each ceiling panel has a first interlocking bracket and an oppositely spaced second interlocking bracket formed along the sides of the ceiling panel. The ceiling system is installed by installing a number of retaining clips along the length of the second interlocking bracket of a panel and then inserting the first interlocking bracket of the next panel in the second interlocking bracket of the first panel so that the retaining clips secure an edge of the first interlocking bracket of the next panel. Subsequent ceiling panels are connected in this manner to form the ceiling panel system.

An elongated structural ceiling grid member including an open-ended upper portion, an open-ended lower portion, and first and second flanges. The open-ended upper section is formed by a floor and a first set of second parallel and spaced sidewalls extending from and substantially perpendicular to the floor. The open-ended upper portion has an opening opposite the floor and defined by the first and second parallel and spaced sidewalls. The open-ended lower portion is formed by a ceiling and a second set of parallel and spaced sidewalls that extend from and are substantially perpendicular to the ceiling. The open-ended lower portion has a second opening opposite the ceiling and defined by the third and fourth parallel and spaced sidewalls. The first flange is attached to and extends perpendicular to the third parallel and spaced sidewall and the second flange is attached to and extends perpendicular to the fourth parallel and spaced sidewall.

A ceiling tile comprises a first layer of material and a second layer of a structurally stiff material distinct from the material of the first layer, positioned to be below the first layer when installed in a ceiling, wherein the second layer can support its weight and the weight of other layers. The first layer is visible through the openings in the second layer when installed. The second layer might be steel, aluminum, copper, bronze, brass, or iron with openings cut into the second layer. The first layer can be acoustical fiber, wool, fabric, wood, leather, rubber, and acrylic and supported the second layer, with the openings being sufficiently arranged so that the first layer is fully supported by portions of the second layer that are not the openings. Three or more layers are also possible, with some or all of the layers are visible through lower layers.
