n ^ssr BrhShimg des Reibungswiderstandes •zwischen Stähltetpnschwellemoaä Bettungn ^ ssr BrhShimg of the frictional resistance • between steel threshold m oaä bedding
Der Heibungswiderstand der Betonschwelle in der Gleisbettung ist verhältnismäßig gering« Er läßt sich dadurch steigern* daß man in der Sehwellenauflagerfläehe Yertiefuogen anbringt* Diese reichen aber n©ch nicht aus, um einen befriedigenden Eeibsngswert au erhaltene Der Reibungswiderstand läßt sieh besonders dadurch steigern -» das 1st das Wesentliche der Erfindung - daß man sswisehen Betonschwellenkörper und Bettung sine Klebemasse bringt wie Bitumen, Asphaltmastix «der dergleichen» im sweclnaäßigsten wird es sein9 wenn man die untere Auflager·» fläche sehon in der Schwellenfabrik mit dieser JElebemasse bestreicht, wobei die Anbringung τοη ?ertiefung®n im Betonkörper besonders günstige Wirkungen su ©rsielen Yersprieht. Man kann auch di© Zlebemasse kars vor dem ferlegen der Schwelle auf die Bettung auftragen«The heat resistance of the concrete sleeper in the track bedding is relatively low. "It can be increased by adding Yertiefuogen in the visual wave support surface. This is not enough to achieve a satisfactory friction value If the essence of the invention is that the concrete sleeper body and bedding are applied with their adhesive mass, such as bitumen, asphalt mastic, "the like" in the most sweaty conditions 9 when the lower support surface is coated with this adhesive mass in the sleeper factory, whereby the attachment is τοη Depressions in the concrete body have particularly beneficial effects su © rsielen Yersprät. You can also apply the Zlebemasse kars to the bedding before removing the threshold «
Die Klebemasse muß so beschaffen sein9 daß sie bei den herrschenden Temperaturint-errallen ihre Wirkung nicht verliert*The adhesive mass must be such 9 that it does not lose its effect at the prevailing temperature drops *
Für Anwendung dieses Terfahrens erscheint der Gebrauch, automatischer Stopfmaschinen, die auch aus anderen Gründen bei den Stahlbetonschwellen besondere Torzüge haben^ besond-rs -günstigFor the application of this method, the use of automatic tamping machines, which for other reasons also appears in the Reinforced concrete sleepers have special gate pulls that are particularly cheap
