Abstract

La présente invention concerne un corps de structure de couplage et de structure de construction portant sur une structure de couplage dans laquelle deux éléments de structure 1, 2 sont connectés. Chaque élément de structure 1, 2 a des parties saillantes 32, 42 intégrées faisant saillie à partir d'une partie latérale (côté A ou côté B). Les deux éléments de structure 1, 2 sont rapprochés, et les parties saillantes 32, 42 sont chevauchées sur les parties latérales (côté A ou côté B) de l'élément de structure homologue 2, 1 de façon à être positionnées sur des côtés opposés l'un à l'autre. Les parties saillantes 32, 42 et les parties latérales (côté A ou côté B) des éléments de structure homologues 2, 1 sont chacune reliées avec des boulons. On obtient ainsi un couplage avec un procédé simple dans lequel, principalement, le nombre de composants utilisés pour connecter des éléments de construction est réduit, et il n'y a pas de projection au-delà des (parties de bride des) éléments de structure.
