Abstract

Bei einem Litzenanker (1), insbesondere zur Anwendung im Bergbau, umfassend eine mehrere Drähte (3) umfassende Litze (2), einem Ankerkopf (14), eine vom Ankerkopf (14) gestützte Ankerplatte (17) zur Auflage auf dem Gestein (18), soll die verdrängte Luft beim Einbringen eines erhärtbaren Materials (11) in das Bohrloch (19) ohne einen gesonderten Schlauch aus dem Bohrloch (19) abgeleitet werden können.In a strand anchor (1), in particular for use in mining, comprising a strand (2) comprising a plurality of wires (3), an anchor head (14), an anchor plate (17) supported by the anchor head (14) for resting on the rock (18 ), the displaced air when introducing a hardenable material (11) into the borehole (19) without a separate hose from the borehole (19) can be derived.

Diese Aufgabe wird dadurch gelöst, dass zwischen den Drähten (3) der Litze (2) wenigstens ein Längskanal (4), vorzugsweise mehrere Längskanäle (4), ausgebildet ist bzw. sind, so dass durch den wenigstens einen Längskanal (4) Luft durch die Litze (2) beim Einbringen von erhärtbarem Material (11) in ein Bohrloch (19) nach außen ausleitbar ist.

Figure imgaf001
This object is achieved in that between the wires (3) of the stranded wire (2) at least one longitudinal channel (4), preferably a plurality of longitudinal channels (4), is formed or, so that through at least one longitudinal channel (4) air through the stranded wire (2) can be deflected outwards when a hardenable material (11) is introduced into a borehole (19).
