Abstract

Structure permettant la liaison d'éléments, pouvant également être appliquée à des éléments de types différents. La structure comprend des premier et second éléments similaires à une plaque (1, 2) qui doivent être reliés, qui présentent chacun des orifices en correspondance (3, 4) et qui sont superposés de façon à être en contact de surface l'un avec l'autre. La structure comprend en outre un élément d'attache (5) dans lequel est formé un orifice fileté (20) continuant vers les orifices (3, 4) des éléments (1, 2) devant être reliés, situé sur le côté opposé de l'élément (2) devant être relié et en contact avec le premier élément (1) devant être connecté, ainsi qu'un élément auxiliaire (7) inséré à l'intérieur de l'orifice fileté (20) de l'élément d'attache (5) et à l'intérieur des orifices (3, 4) des premier et second éléments (1, 2) devant être reliés. L'utilisation d'une chaleur de friction et d'un écoulement de plastique permet au matériau de l'élément auxiliaire (7) d'entrer dans le renfoncement fileté dans l'orifice fileté (20) de l'élément d'attache (5) et de couvrir la périphérie de l'orifice (4) du second élément (2) devant être relié. En conséquence, les premier et second éléments (1, 2) sont reliés.
