Title
(EN) AN ECONOMICAL STEEL ROOF TRUSS
(FR) CHARPENTE DE TOIT EN ACIER ECONOMIQUE
Abstract
(EN)
An economical steel roof truss for spanning large areas with unique shapes for maximum in use strength and splicing segments to use lengths that are easily handled and with a design to use minimum thickness metal consistent with loads and assembly costs.
(FR)
L'invention se rapporte à une charpente de toit en acier économique servant à couvrir de grandes surfaces. Une telle charpente se caractérise par des profilés de formes uniques assurant une résistance maximale pendant l'utilisation et par des segments de jointures en about dont les longueurs facilitent la manipulation, ainsi que par une conception permettant d'utiliser une épaisseur de métal minimale compatible avec les charges soutenues et avec les coûts d'assemblage.
