Abstract
A chemical sliding anchor, in particular for use in mining, for the firm bonding to the rock in a borehole using a fixing agent, comprises an anchor pipe, preferably an anchor nut, anchor plate preferably supported by the anchor nut, for lying on the rock, involving little technical effort by effectively using a sliding function of the sliding anchor in the case of a large change in length of the sliding anchor on absorbing dynamic loads. An elastic element, in particular a spring, is integrated in the sliding anchor and an increase in length of the sliding anchor is effected for a given sliding function with a spring deflection of the elastic element.
Claims17
Chemical sliding anchor especially for use in mining for a firmly bonded fixing to rock in a borehole with fixation equipment, comprising
- an anchor pipe;
- an anchor nut;
- an anchor plate supported by the anchor nut for positioning on the rock,
- wherein an elastic element is integrated in the sliding anchor whereby an increase in the length of the sliding anchor is achieved by a sliding movement on deflection of the elastic element.
