Description
Zweimetallseile für elektrische Leitungen, insbesondere solche aus Stahl und Aluminium, sind in der Regel so aufgebaut, daß die Drähte aus härterem Metall, z. B. Stahl, sich im Innern befinden, während die Drähte aus weicherem Metall, z. B. Aluminium, als ein- oder mehrlagiger Mantel darüber angeordnet sind. Der Stahlbern bann aus einem oder mehreren. Drähten bestehen. Die Zugbelastung des Seiles verteilt sich biei Zweimetallseilen nicht gleichmäßig über den Querschnitt, sondern im Verhältnis, der Ausdehnungs- und Temperaturkoeffizienten. Hieraus ergibt sich eine verschiedenartige Bean- spruchung der Stahl- und Aluminiumdrähte, die mit der Temperatur wechselt. Bei den bekannten Abspannklemmen und Verbindern für Stahl-Aluminium-Seile ist auf diesen Umstand nicht Rücksicht genommen. Diese sind so konstruiert, daß der Stahlkam 'und der Aluminiunimantel ihre gegenseitige Lage zueinander nicht verändern können, so daß kein Belastungsausgleich, eintreten kann. Demnach ist es möglich:, daß der Seilzug, je nachdem die Temperatur hoch oder niedrig ist, einmal mehr von den Aluminiumdrähten, das andere Mal mehr von den Stahldrähten aufgenommen wird. Dieser Mangel tritt vor allem, bei solchen StaU-Aluminium-Seilen in Erscheinung, bei welchen der Stahlkern zwecks Erreichung einer selbsttätigen Schwingüngsdämpfungin dem Aluminiummantel hohl liegt und mit einer gewissen Vorspannung verlegt wird.Two-metal ropes for electrical cables, especially those made of steel and aluminum, are usually constructed in such a way that the wires are made of harder metal, e.g. B. steel, itself located inside, while the wires are made of softer metal, e.g. B. aluminum, as a or multi-layer jacket are arranged over it. The Stahlbern banish from an or several. Wires exist. The tensile load on the rope is distributed over two-metal ropes not evenly across the cross-section, but in proportion to the expansion and temperature coefficients. This results in different types of stress on the steel and aluminum wires, which changes with the temperature. With the known tension clamps and connectors this fact is not taken into account for steel-aluminum ropes. These are constructed in such a way that the steel chamber and the aluminum jacket are in their mutual position can not change each other, so that no load compensation can occur. So it is possible: that the cable pull, ever after the temperature is high or low, one more time from the aluminum wires, the other time more is absorbed by the steel wires. This deficiency occurs especially with such StaU aluminum ropes in Appearance in which the steel core in order to achieve an automatic vibration damping the aluminum jacket is hollow and is laid with a certain pretension.
Zweck der Erfindung ist es, dem Nachteil der bekannten Abspannklemmiein und Verbinder dadurch, abzuhelfen, daß das einmal eingestellte Verhältnis der' Zugbelastungen zwischen Stahlkern und Aluminiummantel auch bei schwankenden Temperaturen unverändert erhalten bleibt. Erreicht wird dieser Zweck dadurch, daß der Stahlkern, und der Aluminiummantel in zwei getrennten, auf der gleichen Achse angeordneten Klemmkörpern gehalten werden, die lerfmdungsgemäß an einem 'doppelarmigen, um einen Aufhängepunkt schwenkbaren Hebel angelenkt sind.The purpose of the invention is to overcome the disadvantage of the known guy clamps and connectors by remedying that the ratio of the 'tensile loads unchanged between steel core and aluminum jacket even with fluctuating temperatures preserved. This purpose is achieved in that the steel core, and the aluminum jacket in two separate clamping bodies arranged on the same axis are held, according to the invention on a 'double-armed, around a Suspension point pivotable lever are articulated.
Die Erfindung ist in der Zeichnung beispielsweise dargestellt.The invention is shown in the drawing, for example.
Abb. ι zeigt die Ausführung der Erfindung als Abspannklemme, teilweise im Schnitt gezeichnet. Fig. Ι shows the embodiment of the invention as an anchor clamp, partially drawn in section.

Wie die Abb. 1 erkennen läßt, besteht die Abspannklemme "aus dem Klemmkörper α für den Aluminiummantel und dem Klemmkörper b für den Stahlkern. Die Festhaltung der Seilteile erfolgt zweckmäßig durch Konen c und d. Es könnten auch andere Klemmorgane, wie z. B. Keile oder Klemmdeckel, Verwendung finden.

The rope parts are expediently held in place by cones c and d. wedges or clamping lid, can be used. at the clamping bodies are carrying arms and / installed, which are to serve ends of a double-armed lever £ · reasonable 6g deflected, the h to the Aufh'angepunkt disposed \ pivotable. h the suspension a clapper pan / 0. like.
