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.

A clip that fixes a ceiling joist intersecting a ceiling joist receiver to the ceiling joist receiver, includes: a top portion having a width of the ceiling joist receiver; a first hanging portion hanging down from one end of the top portion, and provided with, at a lower portion, first engaging projections extending left and right to engage the ceiling joist; and a second hanging portion hanging down from another end of the top portion, and provided with, at a lower portion, second engaging projections extending left and right to lock the ceiling joist. The first hanging portion has a length longer than that of the second hanging portion, and a recess extending in a direction toward the second hanging portion is provided at an intermediate position of the first hanging portion.

A suspended ceiling system (1) comprising a plurality of ceiling tiles and a grid (100) of profiles (40) for supporting the plurality of ceiling tiles, the grid (100) of profiles (40) comprising at least a first and a second profile (40) configured to be interconnected along a longitudinal axis, the first and second profile (40) each comprising two laterally extending flanges (43) and an upstanding web (44) provided with a bulb (41) at its free end, wherein each of the first and second profile (40) has a curved extension and is configured to be installed such that it, in an installed and unloaded condition, bulges in an upward direction.

A radiant ceiling panel for air conditioning of a room, including a radiating surface on which a tube system for conducting a fluid, in particular water, along the radiating surface is fixed, preferably directly. The length of the radiating surface exceeds its width by a multiple. The tube system includes at least two portions fluidically connected in parallel, in particular arranged in parallel. The radiant ceiling panel has a fastening system, in particular a rope-like fastening system, for freely suspended fastening to a ceiling, or at least elements for interacting with said fastening system. The at least two portions are guided together and back apart again in an assembly region of the radiating surface.

A mounting assembly is provided for quick and easy attachment to engineered joists. The mounting assembly includes a brace assembly and a mounting bracket. The mounting assembly may also include an electrical box. The brace assembly is an adjustable member that extends between flanges of engineered ceiling joists. The brace assembly has two low profile end caps that can engage the flanges of engineered ceiling joists and apply a force against the flanges when tightened. The mounting bracket is connected to a hanger body of the brace assembly by a snap fit and the electrical box is attached to the mounting bracket.

A ceiling beam connector that permits the incorporation of ornamental panel designs such as triangles, parallelograms, and trapezoids into suspended ceilings. The connector has a faceplate attached to either two arms or a leg. The leg is attached to either the faceplate or an arm at an acute angle measured from an axis perpendicular to the faceplate. To maintain standard beam lengths and rout spacing at 2 foot, 3 foot, or 4 foot (61 cm, 91 cm, or 122 cm) beam spacing, the leg may project out at the following angles measured from the axis: about 14.0°, about 18.4°, about 26.6°, about 30.3°, about 45.0°, about 59.7°, about 63.4°, about 71.6°, or about 76.0°.
