Abstract

Oppfinnelsen angår en ekspansjonsplugg (10) med en ekspansjonshylse (18) som har fremstående ekspansjonstunger (24), som er ekspanderbare ved hjelp av et konisk ekspansjonslegeme (12). For reduksjon av ekspansjonskraften blir det ifølge oppfinnelsen foreslått at ekspansjonstungene er tildannet med fremstående tenner (28) gjennom utsparinger (26) ved en fremre endekant (20), hvorigjennom flatebelastningen under ekspansjonen blir øket og en inntrengning i en borehullvegg blir lettet.The invention relates to an expansion plug (10) with an expansion sleeve (18) having prominent expansion tongues (24), which are expandable by means of a tapered expansion body (12). In order to reduce the expansion force, it is proposed according to the invention that the expansion tongues are formed with protruding teeth (28) through recesses (26) at an anterior end edge (20), thereby increasing the surface load during the expansion and penetrating into a borehole wall.
