Abstract

L'objet de l'invention concerne un formage d'éléments tubulaires fonctionnels pour la fabrication de serres tunnels et similaires. Il est constitué par un tube ovalisé comportant deux secteurs semi-circulaires, haut et bas, reliés par des faces latérales, rectilignes, parallèles. Il est destiné à la confection des armatures ou arceaux montés par assemblages de secteurs par emboîtages autocentrés sur chantier.
