Abstract

L'objet de la présente invention est de fournir une structure pour la fixation temporaire d'un joint d'étanchéité métallique de manière à permettre une fixation temporaire simple et permettant d'éviter les chutes et mauvais alignements dans la fixation temporaire sans introduire de limites dans l'espace de fixation du côté d'un élément correspondant. La structure de fixation temporaire est conçue de sorte que l'élément correspondant devant être rendu étanche par un joint d'étanchéité métallique composé d'un matériau métallique est doté de multiples trous de boulon et de multiples trous de retenue et de sorte que le joint d'étanchéité métallique est doté de cliquets de fixation temporaire destinés à être insérés dans les trous de retenue. La structure selon l'invention est conçue de sorte que chaque cliquet de fixation temporaire présente une section transversale en forme de U et est temporairement fixé à l'élément correspondant par l'extrémité avant dudit cliquet contiguë à la surface périphérique interne d'un trou de retenue de l'élément correspondant ou à une partie étagée disposée sur le bord périphérique dudit trou de retenue du côté opposé au côté du joint d'étanchéité métallique.
