Abstract

In a base anchorage for heavy machinery, in particular converters, an anchoring plate is concreted into a base and is firmly connected with at least one bolt, whose end projecting out of the base is provided with a screw thread. The at least one bolt is produced of high-tensile strength material and, at its lower end, it is screwed through a threaded bore in the anchoring plate and contacts, with at least one flattened side, a corresponding face of a securing plate fixed relative to the anchoring plate, the bolt thus being secured against rotation.
