Title:
Abstract:	Der Problematik des selbsttätigen Losdrehens wird offensichtlich auch im Stahl- und Metallbau eine solche technische und wirtschaftliche Relevanz beigemessen, dass Keilsicherungsscheiben auch für die Verwendung im bauaufsichtlich geregelten Bereich vorgesehen sind. Die Sicherungswirkung stellt hierbei ein Gebrauchstauglichkeitskriterium dar, welches auf der Ausnutzung einer Vorspannkraft beruht. In diesem Beitrag wird die Verwendung der Keilsicherungsscheiben in Schraubenverbindungen vor dem Hintergrund der derzeitigen Normungslage des bauaufsichtlich geregelten Bereiches diskutiert. Aus den Erfahrungen umfangreicher experimenteller Untersuchungen wird in diesem Beitrag eine Methodik vorgestellt, mit deren Hilfe der Verwendbarkeitsnachweis für Keilsicherungsscheiben experimentell und rechnerisch abgebildet werden kann. A contribution to the use of wedge-lock washers for bolted connections in the building construction authorities regulated field. The problem of self-loosening has obviously such a technical and economic relevance for steel and metal constructions, that wedge-lock washers are also intended to be used in the building construction authorities regulated field. The securing effect of the wedge-lock washers constitutes a criterion of usability, which is based on the utilization of a preload. This article discusses the usage of wedge-lock washers for bolted connections with the background of the present standard situation for the building construction authorities regulated field. Furthermore a procedure is introduced by which the usability of the wedge-lock washers can be determined in an experimental and calculating way.
