Abstract

A rock anchor (1), which can be secured in any position by fitting a tensioner, has a securing section (4) consisting of a tensioning sleeve (6) with a counter taper (7) and a wedge (8) matching the tensioning sleeve (6) which can be fitted over the anchor pin (2). The wedge slope is about 3 DEG , as is that of the taper (7), so that it is possible not only to insert the wedge (8) reliably into the taper (7) but also to apply the tensional forces evenly without peak tensions and consequent wear on the GFP anchor pin. The GFP anchor pin does not have to be slotted; rather, securing is effected by suitably fitting the securing section (4) and fixing the wedge (8) by a tensioner (9) or a tensioning screw (16), so that the fixing may be made at virtually any point on the anchor pin (2).
