Title:
Abstract:	Hybridankerplatten stellen eine vorgefertigte Verankerungslösung für Zugglieder (Spannglieder, Verpressanker) dar, bei der die Werkstoffe ultrahochfester Beton (UHPC) und Stahl oder Kohlefaser entsprechend ihrer Eigenschaften kombiniert werden. Sie wurden erstmals im Juli 2011 bei der Verstärkung des Hauptdrempels der Rheinschleuse in Iffezheim als aufgesetzte Verankerungsplatten für Dauerlitzenanker eingesetzt. Mit den dauerhaften Hybridankerplatten konnte der Ankerkopf bei beengten Verhältnissen äußerst kompakt auf den unbewehrten Altbeton aufgesetzt werden. First application of composite anchor plates (“Hybridanker”) for strengthening a Rhine lock with permanent ground anchors Prefabricated composite anchor plates are using high performance concrete and steel or carbon fibres for load transfer of tendon forces (post-tensioning tendons, ground anchors). First application of the Hybridanker-type has been realized at the Rhine lock in Iffezheim, where permanent multistrand ground anchors had been installed. The prefabricated Hybridanker-solution allowed a durable and compact load transfer to old, unreinforced concrete.
