Abstract
L'invention concerne un appendice de boulon en spirale élastique destiné à être fixé à un boulon d'ancrage, ledit appendice présentant une partie tige cylindrique destinée à être fixée à l'extrémité d'insertion du boulon d'ancrage et une partie cannelure hélicoïdale présentant une pointe destinée à rompre une cartouche de résine et assurant un mélange lors de sa rotation. La tige présente une première partie conique et une seconde partie conique pour résister au mouvement de l'appendice une fois la résine durcie.
