Abstract

Poutre à treillis légère, de hauteur constante, entièrement réalisable à partir de tôles d'acier galvanisé en bobines. Cette poutre est formée de deux membrures en tôle pliée ou formée aux galets et de diagonales en tôle pliée et emboutie. Les membrures et les diagonales sont assemblées entre elles par soudure par points ou par bossages, ce qui n'altère pas la galvanisation. Ces poutres peuvent être utilisées de façon très économique en charpente et en construction : colonnes et fermettes légères, pannes de grande portée, contreventements, etc. La forme des membrures permet des perçages standards et des assemblages faciles par boulonnage, l'encastrement de murs, la fixation de couverture par crochets, l'agrafage de plafonds, etc.
