A reinforced structural member is provided which includes a reinforcing member received in the cavity of a structural member (20). The reinforcing member includes a carrier (28) having divergent, intersecting legs (42, 44) which preferably engage and rest upon the structural member (20), a thermally expandable reinforcing material (30, 34, 36, and 40), and a fastener (32) for coupling the reinforcing material (30, 34, 36, and 40) to the carrier (28). The thermally expandable reinforcing material (30, 34, 36, and 40) is preferably provided as a separate element positioned on the carrier (28), whereby upon activation by heat, the expandable material melts, foams and expands so that after curing, the structural member (20) is bonded to the carrier (28).

L'invention concerne un élément structurel renforcé comprenant un élément de renfort inséré dans la cavité d'un élément (20) structurel. Cet élément de renfort comprend un support (28) doté de pieds (42, 44) divergents intersectés qui entrent de préférence en contact avec l'élément (20) structurel et viennent s'appuyer sur ce dernier, un matériau de renfort (30, 34, 36 et 40) de renfort dilatable par traitement thermique, et un organe (32) de fixation permettant de connecter le matériau (30, 34, 36 et 40) de renfort au support (28). Le matériau (30, 34, 36 et 40) de renfort dilatable se présente de préférence sous forme d'un élément distinct placé sur le support (28). Lorsqu'il est activé par application de chaleur, ce matériau fond, mousse et se dilate de manière qu'après le traitement, l'élément (20) structurel est assemblé au support (28).
