The subject technology relates to resilient channels. Resilient channels are members used in building construction and framing for attaching wall panels, for example gypsum boards, to wall supports, for example, wooden or metal studs. Additionally, resilient channels are used to attach ceiling panels to ceiling supports such as trusses and/or joists. The subject technology applies to both uses, but for brevity, this disclosure will focus on the wall use-case with gypsum boards.
Resilient channels are installed between studs and gypsum boards to provide a space between the boards and studs and to provide acoustical dampening, thereby attenuating the transmission of sound through the resulting wall.
A resilient channel for joining boards to studs, joists or trusses in building construction, and thereby provide acoustic attenuation of sound passing through the structure, is further isolated from the studs, joists or trusses by a bridged mounting flange, and is further isolated from the boards by a bridged face flange. The bridged mounting flange is bridged over the studs, joists or trusses by a pair of feet disposed at opposite ends of the mounting flange and connected by respective bends to the flange. The bridged face flange is bridged over the board by bends disposed at opposite ends of the face flange and/or by corrugations formed in the face flange. Due to the bridged structures of the mounting flange and face flange, the area of contact between the resilient channel and the studs, joists or trusses, and the boards, respectively, is reduced. Thereby the acoustic isolation provided by the resilient channel is improved, resulting in improved sound transmission characteristics of the overall construction.
According to an aspect of the subject technology, a resilient channel for joining a board to a support such as a stud, joist or truss in building construction, has a mounting flange, a face flange, and a web joining the mounting flange and face flange; the mounting flange having a first foot disposed on a first end of the mounting flange and a second foot disposed on a second end of the mounting flange and joined to the web, the first foot and second foot disposed to contact the support and bridge the mounting flange over the support to define a gap between at least a portion of the mounting flange and the support. The first foot is disposed at the end of a bend (which may be a 180-degree bend, so that the first foot is doubled back and under the mounting flange) formed in the mounting flange such that the first foot is disposed between the mounting flange and the support. The face flange is joined by a first bend to the web, and in an embodiment is joined by a second bend to a stiffener on an end of the face flange opposite the web, and has corrugations formed therein between the first bend and second bend. In another embodiment, the second bend joins the face flange to a second web and second mounting flange which is a mirror-image of the first mounting flange.
Moreover, according to an aspect of the subject technology, a resilient channel for joining a board to a support such as a stud, joist or truss in building construction, is in the form of a single piece of steel, and comprises a mounting flange having a first foot and a second foot, the first foot disposed at a first end of the mounting flange and bent back toward the support to be disposed between the mounting flange and the support, the second foot disposed at a second end of the mounting flange and bent toward the support, such that the first foot and second foot are disposed to bridge the mounting flange over the support to define a gap between at least a portion of the mounting flange and the support. The channel also comprises a face flange having a first bend, a second bend, and corrugations, the first bend disposed at a first end of the face flange and the second bend disposed at a second end of the face flange and the corrugations disposed between the first bend and the second bend; and a web joining the second foot of the mounting flange and the first bend of the face flange.
The resilient channel of the subject technology may be installed in a similar fashion.
According to an aspect of the subject technology, in an embodiment, resilient channel 1 has a body made of steel using methods known to the art, for example, by cold rolling. As shown in the Figures, and as best seen in
According to another aspect of the subject technology, in an embodiment, face flange 16 is disposed between bends 15 and 18. Bend 15 joins face flange 16 to web 14. Bend 18 joins face flange 16 to stiffener 19. Face flange 16 incorporates corrugations 17 which rise above the plane of face flange 16.
In the embodiment shown, corrugations 17 take the form of triangle-wave corrugations formed in face flange 16, extending from point 20 to point 21, rising to peaks above the plane of face flange 16 approximately as high as bends 15 and 18. In other embodiments the corrugations may take the form of trapezoids, rounded domes, or other protruding shapes. In other embodiments the corrugations may rise to peaks above the plane of face flange 16 but lower, or higher, than bends 15 and 18. In other embodiments, the corrugations may extend above the plane of face flange 16 in the board-facing direction but not in the stud-facing direction. In the embodiment shown, corrugations 17 have the same height above the plane of face flange 16, however in other embodiments, corrugations may have different heights.
When in use, resilient channel 1 is fastened to metal or wooden studs via fasteners (e.g., nails or screws) passing through mounting flange 12, as shown for example in
Additionally, when in use, gypsum boards or the like are fastened to face flange 16 with fasteners (e.g., screws). Bends 15, 18 are disposed to contact the boards. Face flange 16 is bridged over the boards, except where the peaks of corrugations 17 may contact the boards, as for example when face flange 16 is deflected by fasteners toward the board. In this way, according to an aspect of the subject technology, the contact area between face flange 16 and the boards is reduced, which is expected to improve the sound transmission properties of the overall construction.
In embodiments of the subject technology, the mounting flange structure 12 may be used with a conventional face flange, or the corrugated face flange 16 may be used with a conventional mounting flange structure.
In another embodiment, for example as shown in
