Description

Vorrichtung zum Verankern von Spanndrähten, insbesondere für Spannbeton Die Vorrichtung nach der Erfindung hat den Zweck, einen, zwei oder mehr flache, runde oder ovale Stahldrähte fest einzuklemmen, damit sie großen Zugkräften ausgesetzt werden können. Sie kann vor allen Dingen vorteilhaft für sehr harte Drähte mit großer Zugfestigkeit, wie sie in der Spannbetonfertigung gebräuchlich sind, angewandt werden.Device for anchoring tension wires, in particular for prestressed concrete The device according to the invention has the purpose of one, two or more flat, To clamp round or oval steel wires tightly so that they are exposed to large tensile forces can be. Above all else, they can be beneficial for very hard and large wires Tensile strength, as they are used in prestressed concrete production, can be applied.

Die Vorrichtung besteht in der Hauptsache aus einem Körper mit keilförmigem Hohlraum und einem flachen Keil. Zum Einklemmen werden die Drähte in den keilförmigen Schlitz eingeführt und nach zwei Seiten möglichst gleichmäßig verteilt. Anschließend wird der Keil in der Mitte eingeschoben und fest angezogen. Die so eingekeilten Drähte können dann belastet werden. Der Keil in der Mitte zieht sich bei Belastung in bekannter Weise weiter fest und gewährt so ein unbedingtes Festklemmen der Drähte.The device consists mainly of a body with a wedge-shaped Cavity and a flat wedge. To pinch the wires in the wedge-shaped Slit inserted and distributed as evenly as possible on two sides. Afterward the wedge is pushed in in the middle and tightened firmly. The wedged in like this Wires can then be loaded. The wedge in the middle pulls itself out under load in a known manner further firmly and thus guarantees an unconditional clamping of the wires.

In der Zeichnung sind Ausführungsbeispiele der Erfindung schematisch dargestellt.Exemplary embodiments of the invention are shown schematically in the drawing shown.

Die Abb. 1, 2 und 3 zeigen die einfachste Form der Vorrichtung in zwei Ansichten und einem Schnitt. Der flache Keil b verklemmt zwei bandförmige Spanndrähte.Figs. 1, 2 and 3 show the simplest form of the device in two views and one section. The flat wedge b clamps two ribbon-shaped tension wires.

Die Abb. 4 zeigt eine Lösung, bei der sich die Keile besser anziehen und auch besser lösen lassen und bei der die Sicherheit des Festziehens infolge einer Rollenanordnung größer ist.Fig. 4 shows a solution in which the wedges tighten better and can also be loosened better and with the security of tightening as a result a roller assembly is larger.

Rechts in Abb. 4 liegen die Spanndrähte unmittelbar auf Rollen oder rollenartigen Körpern c, während sie links auf Rollen d mittelbar aufliegen.On the right in Fig. 4 the tension wires lie directly on rollers or roller-like bodies c, while they rest indirectly on rollers d on the left.

Der Neigungswinkel der Keilflächen kann zwischen 0 und 40° liegen.The angle of inclination of the wedge surfaces can be between 0 and 40 °.

Es ist vorteilhaft, die Klemmflächen des Schlitzes aus hartem Material herzustellen und auch den Keil zu härten. Zweckmäßig werden die Klemmflächen des Keils der Drahtform entsprechend ausgearbeitet und aufgerauht.It is advantageous to have the clamping surfaces of the slot made of hard material manufacture and also harden the wedge. The clamping surfaces of the Wedge shaped and roughened to match the shape of the wire.
