Title:
Abstract:	Die Fingerkonstruktion ist eine seit Jahrzehnten eingesetzte Fahrbahnübergangskonstruktion. Durch die Form der Finger erzeugt dieser Fahrbahnübergang besonders geringe Schallemissionen und zeichnet sich durch einen hervorragenden Überfahrkomfort aus. Eine neuartige Verankerungslösung, welche die Verankerungskraft mithilfe spezieller Verankerungskörper direkt aus dem Finger in die Brückenkonstruktion weiterleitet, wird derzeit für die Regelprüfung entwickelt und hier vorgestellt. Für die Sicherstellung der Wasserdichtigkeit stehen inzwischen dauerhafte Lösungen zur Verfügung. An expansion joint system as a finger construction with direct transfer of the anchoring forces into the concrete Finger construction is an expansion joint construction that has been employed for decades. The finger form means that this expansion joint produces particularly low noise emissions and gives it an excellent comfort when passing by vehicles. An innovative anchoring solution, which transfers the anchoring force with the help of special anchoring elements directly from the finger into the bridge construction, is currently in development for standard testing and is presented here. To ensure water-tightness of the finger joint, durable solutions have been developed in the meantime.
