Abstract

Ein selbstbohrender Gebirgsanker (11) weist einen hohlzylindrischen Aufnahmekörper (12), der an einem Ende (13) einen Bohrkopf (16) aufweist, und ein im Aufnahmekörper (12) angeordnetes Innenrohr (21) mit einer zum Bohrkopf (16) beabstandeten Austrittsöffnung (22) zur Aufnahme einer auspressbaren, aushärtbaren Masse (26) auf. Im Innenrohr (21) ist zwischen der aushärtbaren Masse (26) und dem Bohrkopf (16) ein im Innenrohr (21) verschiebbar gelagertes Mischelement (31) vorgesehen. Der Bohrkopf (16) weist eine dem Mischelement (31) zugewandte Aufnahme (18) für ein freies Ende (32) des Mischelementes (31) sowie eine Durchtrittsöffnung (17) für die aushärtbare Masse (26) auf. Die Aufnahme (18) des Bohrkopfs (16) weist einen Zentrierabschnitt (20) und das Mischelement (31) weist an dem, dem Bohrkopf (16) zugewandten freien Ende (32) einen mit dem Zentrierabschnitt (20) der Aufnahme (18) des Bohrkopfs (16) zusammenführbaren Gegenzentrierabschnitt (33) auf.

A self-drilling rock anchor (11) has a hollow-cylindrical receiving body (12) which has a drill head (16) at one end (13) and an inner pipe (21) arranged in the receiving body (12) with an outlet opening spaced apart from the drill head (16) ( 22) for receiving a squeezable, hardenable mass (26). In the inner tube (21) between the hardenable mass (26) and the drill head (16) in the inner tube (21) slidably mounted mixing element (31) is provided. The drill head (16) has a receptacle (18) facing the mixing element (31) for a free end (32) of the mixing element (31) and a passage opening (17) for the hardenable mass (26). The receptacle (18) of the drill head (16) has a centering section (20) and the mixing element (31) has at the, the drill head (16) facing the free end (32) with the centering portion (20) of the receptacle (18) of Drill head (16) merge Gegenzentrierabschnitt (33).
