Abstract

Bei einem Gesteinsanker (1), insbesondere zur Anwendung im Bergbau, umfassend ein Ankerrohr (2), eine Ankermutter (9) mit einem ersten Längsabschnitt (15) zur Einführung innerhalb einer Bohrung (25) und einem zweiten Längsabschnitt (16) zur Stützung einer Ankerplatte (12), die von der Ankermutter (9) gestützte Ankerplatte (12) zur Auflage auf dem Gestein (24), soll die Ankermutter (9) und die Ankerplatte (12) nur wenig Bauraum außerhalb der Bohrung (25) benötigen bei einem geringen Abstand zwischen dem Ankerrohr (2) und der Bohrung (25). Diese Aufgabe wird dadurch gelöst, dass der Gesteinsanker (1) eine ringförmige, das Ankerrohr (2) umschließende Aufweitbohrkrone (13) mit Schneidelementen (14) umfasst zur Vergrößerung des Durchmessers der Bohrung (25) an einem Bereich, bei welchem der erste Längsabschnitt (15) in die Bohrung (25) eingeführt ist.
