Isolated Resilient Channel
A resilient channel for joining a board to a support such as a stud, joist or truss in building construction, has a mounting flange and a face flange joined by a web. The mounting flange has a first foot and a second foot disposed at ends of the flange, the first foot bent back toward the support to be disposed between the mounting flange and the support, the second foot 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 face flange has a first bend and a second bend disposed at ends of the flange, and corrugations between the first bend and the second bend.
1 . A resilient channel for joining a board to a support such as a stud, joist or truss in building construction, the resilient channel comprising:
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.
2 . The resilient channel of claim 1 wherein the first foot is disposed at the end of a bend formed in the mounting flange such that the first foot is disposed between the mounting flange and the support.
3 . The resilient channel of claim 2 wherein the bend is a 180-degree bend.
4 . The resilient channel of claim 1 wherein the mounting flange has through-going holes for passage of fasteners for fastening the resilient channel to the support.
5 . The resilient channel of claim 1 wherein the face flange is joined to the web by a bend.
6 . The resilient channel of claim 1 wherein the face flange has corrugations formed therein.
7 . The resilient channel of claim 1 wherein the face flange is joined by a bend to a stiffener on an end of the face flange opposite the web.
8 . The resilient channel of claim 1 wherein the face flange is joined by a first bend to the web, and is joined by a second bend to a stiffener on an end of the face flange opposite the web.
9 . The resilient channel of claim 1 wherein the face flange is joined by a first bend to the web, and 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.
10 . The resilient channel of claim 9 wherein the first bend, corrugations, and second bend rise to peaks above a plane of face flange.
11 . The resilient channel of claim 10 wherein the peaks of the first bend, corrugations, and second bend all rise to approximately the same height above the plane of the face flange.
12 . The resilient channel of claim 9 wherein the first bend, second bend, and corrugations are disposed to contact the board and bridge the face flange over the board to define a gap between at least a portion of the face flange and the board.
13 . The resilient channel of claim 1 wherein the resilient channel further comprises a second mounting flange joined by a second web to the face flange on a side of the face flange opposite the web.
14 . The resilient channel of claim 6 wherein the corrugations are in the form of a triangle-wave, trapezoids, or rounded domes.
15 . The resilient channel of claim 6 wherein the corrugations extend above the plane of the face flange in a board-facing direction but not in a stud-facing direction.
16 . A resilient channel for joining a board to a support such as a stud, joist or truss in building construction, the resilient channel in the form of a single piece of steel, the channel comprising:
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;
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;
a web joining the second foot of the mounting flange and the first bend of the face flange.
17 . The resilient channel of claim 16 wherein through-going holes are formed in the mounting flange for passage of fasteners for fastening the resilient channel to a support.
18 . The resilient channel of claim 16 wherein the face flange is joined by the second bend to a stiffener.
19 . The resilient channel of claim 16 wherein the first bend, corrugations, and second bend rise to peaks above a plane of face flange.
20 . The resilient channel of claim 16 wherein the face flange is joined by the second bend to a second web and the second web is joined to a second mounting flange.
21 . The resilient channel of claim 20 wherein the second mounting flange comprises a first foot and a second foot, the first foot disposed at a first end of the second mounting flange and bent back toward the support to be disposed between the second mounting flange and the support, the second foot disposed at a second end of the second mounting flange and bent toward the support, such that the first foot and second foot are disposed to bridge the second mounting flange over the support to define a gap between at least a portion of the second mounting flange and the support.
