Abstract

An improved resilient wallboard channel constructed and arranged for attachment to a surface of a framing member and accommodating standard fasteners. Included on the present channel is a first, generally planar surface having an elongate edge, an inclined web disposed along the elongate edge and projecting at an oblique angle relative to the first surface, a web edge of the inclined web opposite the first surface is shared with a second, generally planar surface, a stop flange, which is shorter than the inclined web, projects from a stop flange edge of the second surface opposite the inclined web, and the first surface and the web edge are separated by at least ¾-inch measured normally from the framing member surface.

First claim

The invention claimed is:

1. A resilient wallboard support channel constructed and arranged for attachment to a surface of a framing member and for holding a wallboard panel suspended away from the framing member, comprising:
a first, generally planar surface having an elongate edge, and an opposite free edge which is folded over;
an inclined web disposed along said elongate edge and projecting at an obtuse angle ranging from 110-115° relative to said first surface, said inclined web is provided with a plurality of linearly spaced cutouts for increasing resiliency when mounted to the framing member;
a web edge of said inclined web opposite said first surface is shared with a second, generally planar surface;
an arched support rib formed between adjacent edges of said inclined web and said second surface to provide enhanced structural rigidity;
a stop flange, which is shorter than said inclined web, projects from a stop flange edge of said second surface opposite said inclined web a distance of at least ½ inch, a second arched support rib spaced from said arched support rib and formed between adjacent edges of said second surface and said stop flange, said stop flange projects from said second surface at an angle of 90-110°; and
said first surface and said web edge being separated by at least ¾-inch measured normally from the framing member surface, said distance achieved by a length of said inclined web, said channel being constructed and arranged so that sufficient spacing is created between the wallboard panel and the framing member so that when an installer uses 1¼-inch fasteners to install the wallboard panel to said channel, the fasteners will not reach the framing member, thus preserving the desired spacing and reducing acoustic transmission from the wallboard panel to the framing member.
