Patent

CA 2389158

A construction beam includes a pair of lateral members (608) and a resilient web (600) extending therebetween. The resilience of the web helps to attenuate sound transmission through the beam from one lateral member to the other. The resilient web according to the present invention is conveniently made from a unitary piece of material. The web is preferably (but not necessarily) provided with spacers (512) formed thereon, so that the lateral members can be easily oriented relative to the web and to each other, so as to be self- jigging. The spacers may conveniently be formed by cutting and bending tabs in the material of the web in desired locations.

L'invention concerne une poutre de construction qui comporte une paire d'éléments latéraux (608) et une armature souple (600) entre les deux éléments. La souplesse de l'armature permet de réduire la transmission de son à travers la poutre d'un élément latéral à l'autre. L'armature souple de la présente invention est, de façon pratique, constituée d'une seule pièce. L'armature est de préférence (mais pas obligatoirement) dotée d'entretoises (512) fixées sur ladite armature, de façon que les éléments latéraux puissent facilement être orientés par rapport à l'armature et l'un par rapport à l'autre, de manière à être ajustés automatiquement. Les entretoises peuvent facilement être formées par découpe et fléchissement de languettes dans le matériau de l'armature à des emplacement souhaités.
