Abstract
La présente invention concerne un ancrage à expansion (80) destiné à un trou (H) dans un mur. Cet ancrage comprend un élément expandeur (32) et un élément expansible (34). L'élément expandeur comprend une extrémité menante présentant une partie évasée (40). L'élément expansible peut s'élargir au niveau de son extrémité arrière (48) et vient s'emboîter contre la paroi du trou lorsque l'élément expandeur est introduit dans ledit trou. Lors de son retrait hors du trou, l'élément expandeur se déplace longitudinalement par rapport à l'élément expansible, et son extrémité évasée amène progressivement l'extrémité arrière de l'élément expansible à s'élargir et à se plaquer contre la paroi du trou. Sous l'action de l'extrémité évasée de l'élément expandeur, l'extrémité arrière de l'élément expansible s'élargit obliquement par rapport à l'axe longitudinal de l'élément expandeur. Ainsi, cette méthode de fixation d'un ancrage à expansion dans un mur consiste à (a) placer un élément expandeur et un élément expansible dans un trou et (b) déplacer l'élément expandeur de manière à ce que l'extrémité arrière de l'élément expansible vienne se plaquer contre la paroi du trou.
