Description

Tragseil für Hängebrücken Schwere Tragseile großer Abmessungen für Hängebrücken längen sich infolge der schraubenförmigen Lagerung der Drähte im Seile bei der Belastung. Um diese elastische Dehnung nach Möglichkeit zu verringern, ist bereits vorgeschlagen worden, die Seile mit einer möglichst großen Schlaglänge der Drähte herzustellen. Aber selbst bei den längsten Schlägen, die noch zulässig sind, damit die Drähte im Seile Halt haben, verbleibt stets eine gewisse elastische Dehnung im Seile als Folge der schraubenförmigen Lagerung.Carrying rope for suspension bridges Heavy carrying ropes of large dimensions for Suspension bridges lengthen due to the helical arrangement of the wires in the ropes at the load. In order to reduce this elastic stretching as much as possible, is has already been proposed that the ropes with the greatest possible length of lay Making wires. But even with the longest strokes that are still allowed, So that the wires have a hold in the rope, there is always a certain elastic stretch in the ropes as a result of the helical bearing.

Um diese Dehnung ganz aufzuheben, müssen alle Hohlräume im Seile zwischen den Drähten vollständig ausgefüllt werden. Hierzu hat man eine Mischung aus Leinöl und Mennige vorgeschlagen. Diese findet jedoch keinen Halt im Seile, da bei Beanspruchungen des Seiles durch die Zusammenziehung der Seildrähte die Masse, insbesondere das Öl, aus den Zwischenräumen zwischen den Drähten herausgepreßt wird.In order to completely cancel this stretch, all voids in the rope must be between the wires are completely filled. For this you have a mixture of linseed oil and red lead proposed. However, this does not find a hold in the rope because of stress of the rope by the contraction of the rope wires the mass, especially the Oil, squeezed out of the spaces between the wires.

Nach der Erfindung sollen zur Ausfüllung der Hohlräume von Seilen für Tragzwecke allmählich erhärtende Massen, beispielsweise Pech oder Zement, benutzt werden, deren Verwendung als Füllstoffe bei elektrischen Leitungen und Kabeln an sich bekannt ist, die jedoch dort nur die Aufgabe haben, ein Berühren der einzelnen Drähte untereinander zwecks elektrischer Isolation zu verhindern.According to the invention are intended to fill the cavities of ropes for carrying purposes gradually hardening compounds, for example pitch or cement, are used their use as fillers in electrical wires and cables is known, but the only task there is to touch the individual To prevent wires from one another for electrical isolation.

Durch die Verwendung von Zement und solchen pechartigen Massen, die in kaltem Zustande allmählich erstarren, wird erreicht, daß das mit der Masse kurz vor der Verlegung ausgefüllte Seil während der Verlegung nachgiebig bleibt, also die Handhabung des Seiles nicht behindert.By using cement and such pitch-like masses that gradually solidifying in a cold state, it is achieved that that with the mass is short Rope filled in before laying remains pliable during laying, so does not hinder the handling of the rope.

Nach der Verlegung des Drahtseiles jedoch erstarrt diese Füllmasse und wird unnachgiebig, so daß sie fest in den Seilzwischenräumen sitzenbleibt und eine Zusammenziehung der Seildrähte und damit eine Längung des Seiles bei Zugbeanspruchungen nicht mehr zuläßt.However, after the wire rope has been laid, this filling compound solidifies and becomes unyielding, so that she remains firmly seated in the spaces between the ropes and a contraction of the rope wires and thus an elongation of the rope under tensile loads no longer allows.

PATENTANSPRUCH: Tragseil für Hängebrücken, bei dem die Hohlräume im Seil zwischen den Drähten ausgefüllt sind, dadurch gekennzeichnet, daß als Füllstoff eine Masse, wie z. B. Zement, pechartiger Stoff o. dgl., verwendet ist, die während der Verlegung des Seiles nachgiebig bleibt, nach der Verlegung jedoch erstarrt und das Seil unelastisch macht.PATENT CLAIM: Suspension cable for suspension bridges, in which the cavities in the Rope between the wires are filled, characterized in that as a filler a mass such as B. cement, pitch-like substance o. The like. Is used during the laying of the rope remains flexible, but solidifies after the laying and makes the rope inelastic.
