Abstract

L'invention porte sur un boulon d'ancrage doté d'un élément tubulaire, d'un dispositif situé à une extrémité de l'élément tubulaire afin d'être mécaniquement fixé à l'élément tubulaire à l'intérieur d'un trou d'une face d'ancrage, d'une barre en partie positionnée dans l'élément tubulaire avec une partie filetée qui fait saillie hors de l'élément tubulaire. Cet élément tubulaire comporte des formations qui résistent aux charges et empêchent la barre de sortir de l'élément tubulaire.
