Abstract: A buckle-resistant resilient runner having a thickness of from 0.017 to 0.020 inch is interposed between the framework and the wall-board of a partition having a sound transmission coefficient of 53. A scalloped web connects the wallboard support flange and the flange of the runner which is fastened to the framework. The distance between the support flange and a notch in the scalloped web is equal to or greater than the width of a stop flange on the opposite edge of the support flange. This design makes the runner much more resistant to buckling than a prior art runner made from thicker sheet metal.

Abstract: A clip for connecting a curtain wall stud to the load bearing framework of a building is provided with detents so that the clip may be pushed onto the stud and does not have to be supported by hand while it is being welded to the framework.

Abstract: A web stiffener for use with a channel-shaped framing member to inhibit web crippling is disclosed wherein said web stiffener comprises two opposing integral compression members each having a J-shaped cross-sectional configurational whereby said compression members are adapted for nested insertion opposingly faced, having longer flanges thereof overlapping within a channel of a framing member, and said members capable of being positioned at a random location along a framing member by rotation into position facilitated by inclined edges of said longer flanges, whereby opposite bearing edges of said compression members are adapted to contact opposite arms of a channel-shaped framing member for web stiffening thereof.
