A ceiling grid strut is provided that includes a rail and a strut channel that is integral to the rail. A ceiling grid assembly is provided that includes a first ceiling grid strut, a second ceiling grid strut, a first threaded fastener, a second threaded fastener, and a connector.

A bracket assembly includes an inner plate defining a first end and a second end opposite the first end; an outer plate defining a first end and a second end opposite the first end, the outer plate substantially parallel with the inner plate; a first member extending from the second end of the inner plate, the first member defining a first free end distal to the inner plate; and a second member extending from the second end of the outer plate, the second member defining a second free end distal to the outer plate; wherein at least one of the first free end and the second free end is angled away from the other of the first free end and the second free end, such that a distance between the first member and the second member increases towards the first and second free ends.

A method of reducing sound transmission in a building constructed using horizontal cross laminated timber (CLT) panels to provide a floor of the building and a floor assembly are described. In an implementation, the method includes: attaching a plurality of energy transmission control mounts to a ceiling side of one or more of the cross-laminated timber panels using fasteners; attaching a plurality of furring channels to the energy transmission control mounts; and attaching a cross laminated timber sheet to the plurality of furring channels to form an exposed ceiling layer.

A suspension assembly (10) comprising: a support member (12) for supporting an item; an elongate suspension article (14) defining a securing opening (30); and a securing device (16) on the support member (12). The support member (12) defines an aperture (38) through which the suspension article (14) can be inserted. The securing device (16) has a securing member (68) movable across the aperture (38) between a securing position and a non-securing position. The securing member (68) is receivable through the securing opening (30) in the suspension article (14) to secure the support member (12) to the suspension article (14) when the suspension article (14) is received through the aperture (38) and the securing member (68) is in the securing position.

A bracket assembly for connecting the head track (282) of a partition wall (280) to an overhead structural component (298) of the building has a shaft (102) connected at right angles to a base plate (106), which in turn is connectable to the head track (282) so that the shaft extends substantially vertically upwards. A pair of upwardly extending wings (118) and an apertured intermediate portion (116) allowing the bracket to be slidingly disposed about the shaft. The wings (118) are connectable to arm portions (288), which in turn are connectable to linking flanges (292), connectable to the overhead structure 298. Springs (130, 132) bias the bracket towards a neutral position. The bracket (110) is retained on the shaft by an upper stop (108) and the base plate 106. Apertured stabilising means (122,124) disposed about the bracket (110) form a collar that guides and stabilises the bracket (110) as it slides relative to the shaft (102) during seismic activities.

Bracketry comprising an L-bracket, a T-bracket, and a joist hanger assembly, and methods of installation of the bracketry that eliminate the need to install a heavier duty electrical junction box and the difficulty of removing and reinstalling wiring in a new electrical junction box or fabricate bracing structure at the jobsite when performing a heavy ceiling fan or lighting fixture retrofit have been presented. The bracketry and installation methods are intended to reduce the cost and complexity of performing a retrofit installations.

Angled coupling including main pass-through coupler to allow first threaded rod to pass therethrough and second coupling extending at angle therefrom to receive second threaded rod. Angled coupling can be used for multiple purposes including, but not limited to, adjusting location of threaded rod, seismic restraints, storm surge restraints and/or providing additional mounting points for support members. Main coupler is configured to be secured to any location on first threaded rod without requiring it to be screwed onto first threaded rod. Main coupler may include first half and second half each traversing length thereof, that can be secured together at desired location on first threaded rod. Main coupler may include upper section having first approximately half of body thereof and corresponding threads and lower section having second approximately half of body (opposite first half) and corresponding threads. Angled coupling is made of high strength material (e.g., steel, cast iron, composites).

A ceiling tile clip includes a top wall, a pair of parallel, spaced side walls that extend downwardly from opposite edges of the top wall and flanges at lower edges of the side walls that extend outwardly. The top wall includes a threaded opening in the center thereof. The ceiling tile clip is configured to be attached to an elongated ceiling grid member by a threaded member that threadedly engages the threaded opening. The elongated ceiling grid member has side surfaces and lower flange portions. When the ceiling tile clip is attached to the elongated ceiling grid member, the top wall of the ceiling tile clip is above the elongated ceiling grid member, the side walls of the ceiling tile clip are alongside the side surfaces of the elongated ceiling grid member and the flanges of the ceiling tile clip are above the flange portions.
