Description

Aus schraubenförmig vorgeformten Stäben oder Drähten bestehende Armierung für Seile, elektrische Leiter od. dgl. Die Erfindung betrifft eine aus schraubenförmig vorgeformten Stäben oder Drähten bestehende Armierung für Seile, elektrische Leiter od. dgl., wobei die schraubenförmig vorgeformten Stäbe so um das Seil usw. herumgewunden sind, daß sie eine rohrförmige Umhüllung bilden.Reinforcement consisting of pre-formed helical rods or wires for ropes, electrical conductors or the like. The invention relates to a helical shape preformed rods or wires reinforcement for ropes, electrical conductors or the like, wherein the helically preformed rods so wound around the rope, etc. are that they form a tubular envelope.

Diese Armierungen, die beispielsweise bei elektrischen Leitern an den Stellen vorgesehen werden, wo an den Leitern Klemmen angreifen, haben den Vorteil, daß sie sich an der Baustelle verhältnismäßig leicht anbringen lassen. Es sind höchstens einfache Werkzeuge erforderlich, um die schraubenförmig vorgeformten Stäbe oder Drähte um den elektrischen Leiter usw. herumzuwinden.These reinforcements, which are used, for example, in electrical conductors the places where terminals engage on the conductors have the advantage of that they are relatively easy to attach to the construction site. There are at most simple tools required to make the helical preformed rods or Winding wires around the electrical conductor, etc.

In vielen Fällen werden die Drähte ohne Werkzeug dadurch am Leiter angebracht, daß der Monteur mit einer Hand einen oder mehrere Stäbe am Leiter anhält, während er mit der anderen Hand das Herumwinden der Stäbe vornimmt.In many cases, the wires are attached to the conductor without tools appropriate that the fitter holds one or more bars on the ladder with one hand, while he twists the sticks with his other hand.

Die Aufgabe der Erfindung besteht darin, dieses Anbringen der Armierungen von Hand zu erleichtern. Gemäß der Erfindung sind die für die Armierung verwendeten, schraubenförmig vorgeformten Stäbe oder Drähte, die z. B. aus rundem Draht oder Kunststoff bestehen können, im Mittelteil gerade ausgeführt. Dies bietet den Vorteil, daß die Stäbe oder Drähte mit diesem Mittelteil von einer Hand sehr bequem am Leiter angehalten werden können. Werden beispielsweise die Stäbe mit dem geraden Mittelteil mit der linken Hand am Leiter gehalten, so können zunächst die rechten Endteile mit der rechten Hand herumgewunden werden, und anschließend werden dann die linken Endteile aufgewunden.The object of the invention is this attachment of the reinforcements to facilitate by hand. According to the invention, those used for reinforcement are helically preformed rods or wires, e.g. B. from round wire or Plastic can be made straight in the middle part. This has the advantage that the rods or wires with this middle part of one hand very comfortably on the conductor can be stopped. For example, the bars with the straight middle part held on the ladder with the left hand, the right end parts can first be wound around with the right hand, and then the left End parts wound.

Die Unterteilung der Stäbe in den geraden Mittelteil und die schraubenförmigen Endteile ergibt bei der angesetzten Armierung auch eine größere Steifheit, als wenn die Stäbe fortlaufend schraubenförmig ausgebildet sind.The division of the rods into the straight central part and the helical one End parts also result in greater rigidity when the reinforcement is attached than when the rods are continuously helical.

Die Zeichnung zeigt eine aus schraubenförmigen Stäben gebildete Armierung. Der Mittelteil 1 der Stäbe ist gerade ausgeführt, während die Seitenteile 2 und 3 die übliche Schraubenform aufweisen.The drawing shows a reinforcement formed from helical rods. The middle part 1 of the rods is straight, while the side parts 2 and 3 have the usual helical shape.

Eine Besonderheit der dargestellten Armierung liegt noch darin, daß die von dem geraden Mittelteil auf beiden Seiten ausgehenden Schraubenwindungen gegenläufig sind.A special feature of the reinforcement shown is that the screw turns emanating from the straight central part on both sides are opposite.
