CA 2237525

A spanning or beam member for use in construction having a pair of opposing C-shaped flanges and a corrugated web. Laterally extended protrusions of the web strengthens the beam member by stiffening the web and increasing the load bearing forces that may be carried by the beam member without crushing. The C-shape of the flanges allows welding of the flanges to the protrusions of the web to reduce the unbraced and unstiffened size of the compression elements to allow for construction of beam members of a given strength out of thinner sheet material.

Élément de portée ou poutre de construction comportant une paire d'ailes opposées en forme de C et une âme ondulée. Des protubérances latérales de l'aile renforcent l'élément de poutre en raidissant l'âme et en augmentant les charges qui peuvent être portées par la poutre sans que cette dernière s'effondre. La forme en C des ailes permet le soudage des ailes aux protubérances de l'âme afin de réduire l'encombrement des éléments de compression non raidis et non contreventés et de permettre la construction d'éléments de poutres d'une résistance donnée, à partir de matériaux de plus faible épaisseur.
