Abstract

Dispositif en longueurs partielles comportant un profilé creux protecteur et une échelle de mesure avec coefficients de dilatation différents. Le profilé creux 2 et l'échelle 4 se composent de tronçons, ceux de l'échelle 4 fixés à des tronçons d'un support intermédiaire 5 de coefficient voisin et ces derniers assemblés à ceux du profilé creux 2 avec possibilité de translation longitudinale, de préférence par une couche élastique intermédiaire 5, et des moyens appropriés permettant d'assembler entre eux de façon ajustable plusieurs tronçons successifs. Mode de fractionnement très avantageux, par absence d'erreurs aux joints, pour les grandes longueurs.
