Abstract

L'invention concerne une structure d'étanchéité pour une section de joint entre des éléments de formation de trajectoire, conçue de sorte qu'un élément d'étanchéité soit disposé entre un premier élément de formation de trajectoire et un second élément de formation de trajectoire, l'élément d'étanchéité comprenant une section d'étanchéité montée dans une rainure de montage sans fin disposée dans la surface du premier élément de formation de trajectoire qui est raccordé au second élément de formation de trajectoire. L'élément d'étanchéité (12) est conçu de manière à présenter d'un seul bloc : la section d'étanchéité (12a) ; des sections de patte (12b) faisant saillie vers le côté le long d'une surface d'étanchéité (10) depuis les parties de la section d'étanchéité (12a) qui sont séparées les unes des autres dans la direction périphérique ; et des saillies (12c) faisant respectivement saillie depuis les sections de patte (12b) dans la direction opposée à la direction vers un second élément de formation de trajectoire (6) de manière à être perpendiculaires à la surface d'étanchéité (10). La surface d'étanchéité (10) comprend : des évidements (21) conçus pour loger respectivement les sections de patte (12b) et raccordés à la rainure de montage (19) ; et des trous d'ajustement par serrage (22) comprenant chacun une extrémité ouverte sur l'évidement (21) et permettant aux saillies (12c) d'être ajustées par serrage à l'intérieur. La présente configuration facilite le montage de l'élément d'étanchéité, empêche les erreurs de montage et permet d'avoir une tolérance de serrage uniforme sur toute la périphérie de la section d'étanchéité.
