Abstract (en)

The cable consists of a bundle of tensile wires or bars which are held inside a protective pipe. The cable has anchor elements at both ends where at least one acts as a coupling unit for attaching to corresponding anchor discs so as to anchor the cable in place. The protective pipe consists of two sections in the connection region which have different diameters so as to spread the outgoing sections of the tensile rods/wires. The connection between the two sections is designed so as to be able to take up any displacement between the incoming and outgoing sections of the cable.

Abstract (de)

Bei einem korrosionsgeschützten freien Zugglied, bei dem eine der Ankervorrichtungen als Koppelstelle ausgebildet ist, ist die Verbindung zwischen jeweils zwei Abschnitten der Verrohrung des an die Ankervorrichtung anschließenden Bereichs so ausgebildet, dass Winkeldrehungen und/oder Querverschiebungen zwischen den Achsen des ankommenden Zuggliedteils und des abgehenden Zuggliedteils aufgenommen werden können. Dabei kann die Verbindung des Abschnitts (10) der Verrohrung sowie der Abschnitte (3, 15 und 16) durch infolge Klemmung erzeugten Reibschluss zwischen entgegengesetzt radial von den Abschnitten abstehenden Flanschen (14, 17) und diese zwischen sich einschließenden Flanschringen (18, 19) vorgenommen sein. Zwischen den Flanschringen (18, 19) ist eine ringförmige, elastisch verformbare, dichtende Zwischenlage (20) aus Gummi, Kunststoff oder dergleichen angeordnet. Auf diese Weise können im Bereich einer Koppelstelle Winkelabweichungen und/oder Querbewegungen aufgenommen werden, ohne Schäden an der Verrohrung befürchten zu müssen und ohne die Zuverlässigkeit des Korrosionsschutzes zu gefährden. <IMAGE>
