A steel wall stud has a rear wall, two parallel side walls, each side wall having a front end wall that projects away from interior cavity formed by the rear and side walls.

An elongate profile (1) having a first portion (2) and a second portion (3), the first and second portions (2, 3) being joined together at a first joining portion (JP1), the first and second portions (2, 3) being non collinear, the joining portion (JP1) comprising an array of raised or rebated formations (10a), each formation extending across the joining portion (JP1) in a direction which is non-parallel to the principal axis of the profile and flat lands being provided between successive formations in an array (10A) and the pitch (P) between successive formations in an array being from 2 to 20 times, for example from 5 to 15 times, the thickness (G) of the flatlands.

The track is elongate such that it extends along a longitudinal axis. The track comprises an alignment feature located at a predetermined alignment position along the longitudinal axis of the track. The alignment feature is configured to secure a partition support member at the alignment position when the partition support member is received by the track. The alignment feature comprises one of a projection or recess configured to engage with the other of a projection or recess of the partition support member.

Building stud (10) for forming a framework for mounting wall panels, comprising a first (12) and a second (14) flange portion and a web portion (16) interconnecting the flange portions. The flange portions comprise a planar, elongated wood fibre member (18, 20), and the web portion comprises a sheet metal member (22) including a first (24) and a second (26) rectilinear line of weakness, which lines of weakness are parallel and along which the sheet metal member is foldable to enable folding the building stud from a retracted storage position to an expanded mounting position.

A dry partition wall system comprising a plurality of wall elements, a floor-side connection element extending over several wall elements, a ceiling-side connection element extending over several wall elements, in which the plurality of wall elements are arranged side by side and are retained on the floor-side connection element and on the ceiling side-connection element and thus jointly form a partition wall, and in which the wall elements are of a multi-layer design.

A framing system includes a first connection assembly that engages with a substrate. The first connection assembly includes a first connector and a track. At least one spring flange defined by the first connector engages with a fastener positioned along the substrate to maintain the first connection assembly in a fixed position relative to the substrate and to interconnect the substrate with the track. The framing system further includes a second connection assembly defining a second connector engaged to a stud. The second connection assembly engages with the first connection assembly to interconnect the stud with the track.

An elongate profile having a first portion and a second portion, the first and second portions being joined together at a first joining portion, the first and second portions being non collinear, the joining portion comprising an array of raised or rebated formations, each formation extending across the joining portion in a direction which is non-parallel to the principal axis of the profile and flat lands being provided between successive formations in an array and the pitch between successive formations in an array being from 2 to 20 times, for example from 5 to 15 times, the thickness of the flatlands.

A support wall frame system includes at least one end track, and a frame member received within the at least one end track. Such a frame member has a centrally registered longitudinal axis and includes at least one rib extended parallel to the centrally registered longitudinal axis. Advantageously, the at least one rib is statically affixed to the at least one end track. The at least one track includes at least one detent spaced from each shoulder of the track to allow bending the at least one track from a single and unitary sheet of metal. The at least one rib is interfitted within the at least one track.

A method for obtaining a vertical or horizontal profiled element for the interconnection of plasterboard panels to walls, in particular to plasterboard walls that can be applied to in-wall frames for retractable sliding doors or for the provision of drywall dividing walls. The method entails a continuous machining of a metallic lamina by punching or drawing or rolling obtained by using two rollers, one acting as a die and the other acting as a punch, so as to obtain on the metallic lamina a plurality of holes, which are uniformly distributed according to a series of mutually parallel rows.

An inter-tenancy partitioning system installed between floor and ceiling slabs has aligned dual spaced apart ceiling and floor channels formed by channel forming members. Dual panels are supported vertically within the aligned dual ceiling and floor channels Each panel having a width less than that of each channel and the channels are spaced apart to provide a gap between the panels. The panels have a height of greater than 2800 mm and extend through a suspended ceiling to engage the respective channel forming members at the ceiling slab above the suspended ceiling. Outer vertical pieces of the channel forming members of the floor channels have a height that does not extend vertically beyond an upper surface of the adjacent floor covering.
