Abstract

L'invention porte sur un tube (14) pour boulons d'ancrage de fixation de câbles ou de fers tenseurs. Le tube, qui est déformé pour pouvoir être vissé, assure en outre un bon accrochage dans le mortier. Il est également prévu un accessoire (26, 46) se montant à l'arrière du boulon dans lequel l'orifice (31) d'introduction du mortier communique avec le passage du câble (34). En outre, on peut fixer plusieurs ancrages (57) de câbles à l'extrémité distante du boulon lorsqu'il est utilisé dans des sols tendres tels que le grès.
