Abstract (en)

The invention concerns a method for assembling at least two simple sheet metal elements (1, 2, 3,; 11, 12, 21, 21', 22, 22') for producing a structural part with open section, preferably U-shaped, or closed section, at least one of the metal elements having a high or very high yield strength and low deformability. The invention is characterised in that the metal elements are formed by at least a folding process; the metal elements are arranged relative to each other along a junction section; the metal elements are assembled by a crimped lap-joint (4) along the junction section of said elements.

Abstract (fr)

La présente invention de rapporte à un procédé d'assemblage d'au moins deux éléments métalliques dont l'un, au moins, présente une haute ou très haute limite d'élasticité le long d'une section de jonction en vue de créer une structure plus complexe, caractérisé en ce que l'assemblage est effectué par sertissage par ourlet le long de la section de jonction des éléments entre eux. <IMAGE>
