ABSTRACT:
A tie rod with a fastening section presenting several spreading cones is provided with a cage which divides the hardenable mortar composition used for the fastening in a cylindrical bore hole into segments. On the occurrence of a crack through the fastening ground of the bore hole, a respreading of the mortar shell formed by the hardenable mortar composition is made possible by a tensile force on the tie rod.
