Abstract

Bei einer Bewehrungs- und/oder Ankerschraube (1) zur Anwendung im Berg- und/oder Tunnelbau und zum Einschrauben in ein anstehendes Gestein (7), umfassend einen Schraubenkopf (2), ein Schraubenende (3), einen Schraubenschaft (4) und ein wenigstens teilweise an dem Schraubenschaft (4) ausgebildetes Gewinde (5), soll die Bewehrungs- und/oder Ankerschraube (1) mit einem geringen technischen Aufwand, preiswert und zuverlässig im anstehenden Gestein (7) befestigt werden können. Diese Aufgabe wir dadurch gelöst, dass das Verhältnis zwischen der Länge der Bewehrungs- und/oder Ankerschraube (1) und dem Außendurchmesser der Bewehrungs- und/oder Ankerschraube (1) größer als 20, 30, 50 oder 70 ist.
