摘要：
A resiliently flexible construction beam includes a pair of lateral flange portions and a web extending therebetween, preferably, but not necessarily, so as to present a cross-sectional profile corresponding to commonly used construction beam members (e.g., 2nullnull4null or 2nullnull6null). The resilience of the beam helps to attenuate sound transmission through the beam from one lateral member to the other. In particular, in a wall frame, beams according to the present invention are mounted at opposite ends thereof to end plates. In one example, the end plates include slits into which the webs of the beams can be received. The resilient web according to the present invention is conveniently made from a unitary piece of material such as, for example, steel.
