Anchor bolts which are inserted into the hole of any component and comprising a pulling bolt having a threaded segment and a following truncated head part are well known and have proven their practical usefulness. Existing anchor bolts should be improved in such a way that a higher load bearing capacity is obtained while reducing the initial force required to insert the anchor bolt. According to the invention, the middle area of every second side of the polygon is provided with a predetermined break-off line. The sides lying in- between exhibit a solid lining from one crest limit to another. In order to produce a corner connection, profiled strips are assembled to a frame by nonpositive screwing of the anchor bolts.

Les boulons d'ancrage destinés à être insérés dans un trou d'une pièce quelconque et comprenant un boulon de tension présentant une section filetée prolongée d'une section tête tronconique ont fait leurs preuves sur le marché. Il convient d'améliorer ce type de boulons de façon à obtenir une portance de charge plus élevée en cas de réduction de la force initiale appliquée lors de l'installation du boulon de tension. Selon l'invention, la zone centrale d'un côté sur deux du polygone est dotée d'une ligne de rupture théorique et les côtés intermédiaires présentent un revêtement plein d'une limite de crête à l'autre limite de crête. Pour produire une liaison angulaire, des baguettes profilées sont assemblées par liaison de force par visage à l'aide d'un boulon d'ancrage.
