Abstract
A tie rod, for insertion into an anchorage where it is secured by at least one of an organic and inorganic mortar composition has an axially extending shaft ( ) with an axially extending connection section ( ) and an axially extending anchoring section ( ). The anchoring section ( ) has at least two conically shaped members, one following the other in the axial direction and with the outside diameter of the members increasing toward a leading end of said anchoring section. The conically shaped members ( ) include a first cone ( ) at the leading end of the shaft, inserted first into the anchorage and secured to the shaft ( ) so that it cannot be shifted axially. At least one second cone ( ) separate from the first cone can be slipped onto the anchoring section ( ) of the shaft so that it can be shifted to a limited axial extent along the anchoring section ( ).
