Abstract

L'invention concerne une vis d'armature et/ou d'ancrage (1) destinée à être utilisée dans l'industrie extractive et/ou la construction de tunnels et conçue pour être vissée dans une roche affleurante (7), comprenant une tête de vis (2), une extrémité de vis (3), une tige de vis (4) et un filetage (5) formé au moins partiellement sur la tige de vis (4). L'objectif de cette invention est de créer une vis d'armature et/ou d'ancrage pouvant être fixée dans la roche affleurante sans grande complexité technique, de manière économique et fiable. A cet effet, le rapport de la longueur de la vis d'armature et/ou d'ancrage (1) et du diamètre extérieur de cette vis d'armature et/ou d'ancrage (1) est supérieur à 20, 30, 50 ou 70.
