Abstract

Tube métallique permettant d'obtenir une plus grande résistance principalement à la flexion pour un poids linéaire égal à un tube ovale ou elliptique Il est constitué par un tube dont la section épouse une forme de 8 dont les parois ne sont pas jointives dans la partie contenant les deux axes de symétrie. L'invention peut être utilisée pour la construction de tout ouvrage tubulaire et particulièrement d'échafaudage
