Title:	Ermittlung eines Designraums zur Mechatronisierung von Befestigungsmitteln am Beispiel von Verbundankern
Abstract:	Mit steigender Digitalisierung im Bauwesen werden zunehmend Sensordaten für die Zustandsanalyse von Bauwerken notwendig. Als lasteinleitende Bauteile eignen sich insbesondere Befestigungsmittel zur Integration sensorischer Elemente. Jedoch ist bisher nicht bekannt, wie sich sensorische Elemente auf die Primärfunktion “Haltekraft” auswirken. Dieser Beitrag untersucht die Effekte zusätzlich eingebrachter Elemente zur Ermittlung möglicher Designräume am Beispiel eines Verbundankers. Hierzu wurden an zuvor bestimmten Wirkflächen und Begrenzungsflächen Elemente in Verbundanker integriert und in einem vollfaktoriellen 33-Versuchsplan experimentell untersucht. Die Effekte der Faktorstufen gegenüber der Primärfunktion wurden statistisch interpretiert. Es kann gezeigt werden, dass im System Verbundanker Designraum für den Einsatz sensorischer Elemente vorhanden ist, der genutzt werden kann, um sensorische Verbundanker zu entwickeln, ohne die Verbundspannung signifikant zu beeinflussen. Detection of a design space to mechatronize fastening elements by the example of chemical anchors With increasing digitalization in the construction industry, sensor data are increasingly necessary for the condition analysis of buildings. Fasteners are particularly suitable as load-introducing components for the integration of sensor elements. However, it is not yet known how sensory elements affect the primary function “load capacity”. This paper examines the effects of additionally introduced elements to determine possible design spaces using the example of a chemical anchor. For this purpose, elements were integrated into chemical anchors at previously determined working and limiting surfaces and experimentally investigated in a full-factorial 33 test design. The effects of the factor stages compared to the primary function were interpreted statistically. It can be shown that there is design space in the system of chemical anchors for the use of sensory elements, which can be used to develop sensory chemical anchors without significantly influencing the bond stress.
