Beschreibung
Zusammenfassung:	The invention relates to an anchor having a sleeve, a bolt that passes through the sleeve, and at least one spreading element, which is axially mounted upstream of the sleeve, and which is axially supported on the sleeve, wherein the bolt has a spreading region for the spreading element. According to the invention, the sleeve is of wave shape having axially extending wave crests, in which both the outer radius of the sleeve and the inner radius of the sleeve each have a maximum, and having axially extending wave troughs, in which both the outer radius of the sleeve and the inner radius of the sleeve each have a minimum. L'invention concerne un dispositif d'ancrage comportant un manchon, un boulon traversant le manchon, et au moins un élément d'expansion monté axialement en amont du manchon et en appui axialement contre ce manchon, le boulon présentant une zone d'expansion pour l'élément d'expansion. Selon l'invention, le manchon présente une forme ondulée qui comprend des crêtes s'étendant axialement et au niveau desquelles le rayon extérieur du manchon ainsi que le rayon intérieur du manchon présentent respectivement une valeur maximale, et qui comporte des creux s'étendant axialement et au niveau desquels le rayon extérieur du manchon ainsi que le rayon intérieur du manchon présentent respectivement une valeur minimale.
