<p>An injection anchor is characterised by an anchoring rod (1) that encloses a central longitudinal channel (2) and whose end facing the bore hole opening is set into a jacket tube (7), leaving an intermediate ring-shaped space (8). The jacket tube (7) is fixed at least at its end on the side of the bottom of the bore hole by means of a threaded sleeve (10) that engages the outer thread of the anchoring rod (1) and the inner thread of the jacket tube (7). The length of the jacket tube (7) defines a longitudinal adhesive section (12) and a free section. In a first step, the injection anchor allows the bore hole (6) to be completely filled through the longitudinal channel (2) with a curable medium, thus producing the adhesive section (12), whereas the anchoring rod located inside the partial longitudinal section (9) does not interact with said medium. In a second step the jacket space (8) located between the inner side of the jacket tube (7) and the outer side of the anchoring rod (1) may also be filled with the curable medium, so that the anchoring rod (1) is firmly fixed over its whole length to the walls of the bore hole (6). This injection anchor is thus extremely easy to work with.</p> |
