Abstract

Boulon extensible pour l'assemblage d'éléments de construction exposés à des chocs thermiques. Il comporte un manchon de liaison thermique entourant la tige extensible et qui remplit approximativement l'espace compris entre la tige extensible et le trou de passage de celle-ci, afin d'améliorer le transfert de la chaleur au boulon et d'obtenir ainsi une réduction des tensions thermiques. Applications : aux carters de machines thermiques.
