Abstract

L'invention concerne une poutrelle comprenant au moins un élément de membrure allongé en acier formé à froid; une armature en acier formée à froid présentant une pluralité d'éléments et des moyens permettant de fixer celle-ci sur l'élément de membrure. Une pluralité de poutrelles est à utiliser, en général, dans un système support destiné à une plate-forme ou une terrasse dans la construction de planchers et de toits. Le système support peut être spécialement utilisé dans des systèmes de plancher et de toit composites.
