摘要
The invention relates to a sliding anchor bolt (10) for introduction into a bore. The sliding anchor bolt (10) has a anchor bolt rod (12), disposed on which is a sliding control element (14) having a through-opening (18), through which the anchor bolt rod (12) extends. The sliding control element (14) comprises a sliding body cage (16) having at least one recess (20) for receiving a sliding body (22) that is in contact with the lateral surface of the anchor bolt rod (12). For precise and repeatable setting of a predefined breakaway force, each recess (22) for receiving a sliding body (22) is disposed in the sliding body cage (22) tangentially relative to the lateral surface of the anchor bolt rod (12). Furthermore, the lateral enveloping surface of each recess (20) projects by a predefined dimension into the free cross section of the through-opening (18), and each sliding body (22) fills the cross section of the recess (20) associated with it.
