Abstract

Beschrieben und dargestellt ist ein Selbstbohranker (1) mit einem zylinderförmigen Ankerrohr (2) und einer Bohrkrone (3), wobei das Ankerrohr (2) auf seiner Außenfläche (4) wenigstens eine spiralförmig verlaufende Profilierung (5) aufweist, wobei die Bohrkrone (3) am setzrichtungsseitigen Ende (6) des Ankerrohrs (2) befestigt ist, und wobei in dem Ankerrohr (2) eine aushärtbare Masse (10) angeordnet ist, die durch eine Auspresseinrichtung in Richtung der Bohrkrone (3) verbringbar ist.Described and illustrated is a self-drilling anchor (1) with a cylindrical anchor tube (2) and a drill bit (3), wherein the anchor tube (2) on its outer surface (4) has at least one spirally extending profiling (5), wherein the drill bit (3 ) at the setting direction end (6) of the anchor tube (2) is fixed, and wherein in the anchor tube (2) a curable material (10) is arranged, which can be brought by a squeezing device in the direction of the drill bit (3).

Ein Selbstbohranker (1), der durch einen einfachen und robusten Aufbau auch für Schlagbohren und damit für die Anwendung in besondern harten Gesteinen geeignet ist, ist dadurch gekennzeichnet, dass ein Innenrohr (7) als Spülkanal innerhalb des Ankerrohrs (2) angeordnet ist, dass das Innenrohr (7) mit Austrittsöffnungen (8) in der Bohrkrone (3) in Verbindung steht, und dass der zwischen Innenrohr (7) und Ankerrohr (2) ausgebildete Ringspalt (9) in Längserstreckung des Ankerrohrs (2) zumindest teilweise mit der aushärtbaren Masse (10) gefüllt ist.
