The structure comprises cold-formed sections built-up from elementary sections (3, 5) joined stably together by means of connecting braces (7) inside the built-up section; said joined elementary sections define longitudinal slots (9, 10) with their longitudinal lips (3A, 5A) which are bent inwards and each inclined with respect to that opposite so as to converge towards the interior; fastening devices comprising a channel die (61) and one or more pressure pieces (81) are fitted along the slots in order to clamp with screw means (98) the lips (3A, 5A) that define said slots and deform them with a locking action.
La structure comprend des profilés formés à froid, composés d'éléments de profilés (3, 5) reliés ensemble de manière stable au moyen d'attaches de liaison (7) situées à l'intérieur du profilé formé. Lesdits éléments de profilés délimitent des fentes longitudinales (9, 10) dont les lèvres longitudinales (3A, 5A) sont recourbées vers l'intérieur et inclinées chacune par rapport à la lèvre opposée de telle sorte qu'elles convergent vers l'intérieur. Des dispositifs de fixation comprenant une pièce filetée en U (61) et une ou plusieurs pièces d'appui (81) sont disposés le long des fentes de manière à serrer lesdites lèvres (3A, 5A) définissant les fentes au moyen de vis (98), et à les déformer en exerçant une action de verrouillage.
