Abstract

Die Erfindung betrifft ein Deckbandsegment (20) zur Anordnung an einer Schaufel (12), insbesondere einer Gasturbinenschaufel, mit einer gegenüber einer Deckbandsegmentoberfläche (24) erhabenen Versteifungsstruktur (22), wobei die Versteifungsstruktur (22) wenigstens bereichsweise kreuzförmig ausgebildet ist. Die Erfindung betrifft weiterhin eine Schaufel (12), insbesondere eine Gasturbinenschaufel, für eine Strömungsmaschine, mit einem an einem radialen Endbereich der Schaufel (12) angeordneten Deckbandsegment (20), welches eine gegenüber einer Deckbandsegmentoberfläche (24) erhabene Versteifungsstruktur (22) aufweist, wobei die Versteifungsstruktur (22) wenigstens bereichsweise kreuzförmig ausgebildet ist.
