ABSTRACT:
An undercut anchor element comprising a shank of an anchor bolt. The shank passes through a base part, which is provided for effecting an anchoring, passes through a spacer sleeve, and at the end thereof is provided with a tightening head. The tightening head can be pulled inside the base part, which is subdivided into anchoring segments by slots provided over a portion of the length of the base part. The slots lead from the front free end of the base part up and into the area of an encircling groove. The anchoring segments have the outer shape of two truncated cones which coincide with their ends that have a smaller diameter. The truncated cone that is located in front in a direction of mounting has an obtuse cone angle of greater than 150° and the adjoining truncated cone has an acute cone angle of less than 30°.
