Definitions
- the present invention relates to a device for twisting wires, having a twisted rod which is rotated when a handle part is pulled and is provided with a binding hook for gripping a wire loop.
- This twisting device consists of a rod with a hook, the rod being twisted and running in a corresponding handle, so that when the handle is pulled, the rod and thus the hook are set in rotation.
- the hook is removed from the rings or eyelets. If the loops are tightened too much, they may break. Therefore, the people working in the chord will be careful not to tighten the loops too tight, which may result in a connection that is too loose.
- the device according to the invention can be used with particular advantage in connection with a device for connecting at least two rods according to PCT-A-WO87 / 01753, after which the connection of two reinforcing iron rods from above without having to pull the wire by hand under the iron, he follows.
- Fig. 1 the lower part of a device is shown, i.e. the binding hook and a mechanism for pivoting and releasing the same.
- This release mechanism makes it possible to twist the wires in a single pulling movement and pull the binding hook out of the loop.
- the end of the twisted rod 1 can be seen at the top, which is connected to a housing 3 via a rivet 2.
- the twisted rod simply merges into the binding hook.
- the binding hook 4 is connected in an articulated manner to the lower part of the housing 3 via an axis 5, as can be seen in particular from FIG. 4.
- the binding hook 4 is formed in two parts, with both legs 4a and 4b at the front, i.e. at the hook end 4c, bent and riveted at the back.
- the legs 4a and 4b of the binding hook each have an indentation 6 into which a locking slide 7 engages.
- this locking slide is T-shaped and is pressed into the indentations 6 by a compression spring 8.
- the compression spring 8 is supported on a guide disk 9 which rests on the short legs of the locking slide.
- the compression spring 8 is guided with the leg of the locking slide 7 running therein in a bore 12 of a guide piece 10 and is supported there at its other end.

Description
Die vorliegende Erfindung bezieht sich auf eine Vorrichtung zum Verdrillen von Drähten, mit einem verdrillten Stab, der beim Ziehen eines Griffteils in Drehung versetzt wird und mit einem Bindehaken zum Erfassen einer Drahtschlinge versehen ist.The present invention relates to a device for twisting wires, having a twisted rod which is rotated when a handle part is pulled and is provided with a binding hook for gripping a wire loop.
Es sind eine Vielzahl von Vorrichtungen zum Verdrillen von Drähten bekannt, um das Befestigen von Armierungseisen durchzuführen, wobei diese Arbeiten meistens von Spezialisten im Akkord ausgeführt werden. Dabei liegen die Armierungseisen, die für die Herstellung von Stahlbeton-Bauwerken verwendet werden, in der Regel orthogonal aufeinander und müssen an ihren Kreuzungsstellen miteinander verbunden werden. Zur Zeit herrscht ein einfaches Gerät vor, bei welchem es vorwiegend auf die Geschicklichkeit und Ausdauer des spezialisierten Arbeiters ankommt. Dabei werden vorgefertigte Drahtschlaufen verwendet, die an ihren beiden Enden Ringe oder Oesen aufweisen. Infolge der erwünschten Flexibilität und dadurch geringen Dicke des Drahtes, werden aus Sicherheitsgründen jeweils zwei dieser Drahtschlaufen von Hand um die zu verbindenden Stäbe gesteckt und oben die vier Drahtoesen durch ein Verdrillgerät erfasst. Dieses Verdrillgerät besteht aus einem Stab mit Haken, wobei der Stab verdrillt ist und in einem entsprechenden Griff läuft, so dass beim Ziehen des Griffes der Stab und somit der Haken in Drehung versetzt wird. Etwa beim Ende des Verdrillvorganges, und dies ist ausschliesslich Sache der Erfahrung und Geschicklichkeit der bedienenden Person, wird der Haken aus den Ringen oder Oesen ausgehängt. Werden die Schlaufen zu stark angezogen, kann es vorkommen, dass sie brechen. Deshalb werden die im Akkord arbeitenden Personen bedacht sein, die Schlaufen nicht zu fest anzuziehen, wodurch unter Umständen eine zu lockere Verbindung entsteht.A large number of devices for twisting wires are known for carrying out the fastening of reinforcing irons, this work being mostly carried out by specialists in the chord. The reinforcing bars used for the manufacture of reinforced concrete structures are usually orthogonal to each other and must be connected to each other at their crossing points. At the moment there is a simple device, which mainly depends on the skill and endurance of the specialized worker. Prefabricated wire loops are used, which have rings or eyelets at both ends. As a result of the desired flexibility and thus the small thickness of the wire, two of these wire loops are put by hand around the rods to be connected for safety reasons and the four wire eyelets are gripped by a twisting device. This twisting device consists of a rod with a hook, the rod being twisted and running in a corresponding handle, so that when the handle is pulled, the rod and thus the hook are set in rotation. Around the end of the twisting process, and this is exclusively a matter of the experience and skill of the operator, the hook is removed from the rings or eyelets. If the loops are tightened too much, they may break. Therefore, the people working in the chord will be careful not to tighten the loops too tight, which may result in a connection that is too loose.
Es ist davon ausgehend Aufgabe der vorliegenden Erfindung eine Vorrichtung zum Verdrillen von Drähten anzugeben, die stets eine maximale Befestigung gewährleistet und ein automatisches Lösen des Bindehakens aus der Schlinge ermöglicht. Eine Vorrichtung, die diese Aufgabe löst, ist in den Ansprüchen beschrieben.Based on this, it is an object of the present invention to provide a device for twisting wires, which always ensures maximum fastening and enables the binding hook to be released automatically from the loop. A device that solves this problem is described in the claims.
Die erfindungsgemässe Vorrichtung kann mit besonderem Vorteil im Zusammenhang mit einer Vorrichtung zum Verbinden von mindestens zwei Stäben gemäss PCT-A-WO87/ 01753 verwendet werden, wonach das Verbinden von zwei Armierungseisenstäben von oben, ohne den Draht von Hand unter die Eisen durchziehen zu müssen, erfolgt.The device according to the invention can be used with particular advantage in connection with a device for connecting at least two rods according to PCT-A-WO87 / 01753, after which the connection of two reinforcing iron rods from above without having to pull the wire by hand under the iron, he follows.

In Fig. 1 ist der untere Teil einer Vorrichtung dargestellt, d.h. der Bindehaken und ein Mechanismus zum Schwenken und Auslösen desselben. Durch diesen Auslösemechanismus ist es möglich, in einer einzigen Ziehbewegung die Drähte zu verdrillen und den Bindehaken aus der Schlaufe zu ziehen. Man erkennt oben das Ende des verdrillten Stabes 1, der über eine Niete 2 mit einem Gehäuse 3 verbunden ist. Bei den vorbekannten Geräten geht der verdrillte Stab einfach in den Bindehaken über. Bei der erfindungsgemässen Ausführung jedoch ist der Bindehaken 4 über eine Achse 5 gelenkig mit dem unteren Teil des Gehäuses 3 verbunden, wie insbesondere aus Fig. 4 hervorgeht. Wie in Fig. 4 dargestellt, ist der Bindehaken 4 2-teilig ausgebildet, wobei dessen beide Schenkel 4a und 4b vorne, d.h. beim Hakenende 4c, abgebogen und hinten vernietet sind.In Fig. 1 the lower part of a device is shown, i.e. the binding hook and a mechanism for pivoting and releasing the same. This release mechanism makes it possible to twist the wires in a single pulling movement and pull the binding hook out of the loop. The end of the
An seiner dem verdrillten Stab zugekehrten Seite, gegenüber dem Hakenende, weisen die Schenkel 4a und 4b des Bindehakens je eine Einbuchtung 6 auf, in welche ein Sperrschieber 7 eingreift. Nach Fig. 3 ist dieser Sperrschieber T-förmig ausgebildet und wird von einer Druckfeder 8 in die Einbuchtungen 6 gedrückt. Dabei stützt sich an diesem Ende die Druckfeder 8 auf eine Führungsscheibe 9 ab, die auf den kurzen Schenkeln des Sperrschiebers aufliegt. Die Druckfeder 8 wird mit dem darin laufenden Schenkel des Sperrschiebers 7 in einer Bohrung 12 eines Führungsstückes 10 geführt und an ihrem anderen Ende dort abgestützt. Das Führungsstück 10 ist im Gehäuse 3 befestigt, siehe Fig. 2. Die unteren Kanten 11 des Sperrschiebers, die in die Einbuchtungen 6 eingreifen, sind nur wenig gebrochen, um eine gute Verriegelung zu gewährleisten.On its side facing the twisted rod, opposite the end of the hook, the
Der Sperrschieber 7 wirkt nicht nur auf den Bindehaken 4, sondern auch auf eine Klinke 13, die drehbar um einen Zapfen 14 und innerhalb der beiden Schenkeln 4a und 4b des Bindehakens angeordnet ist. Wenn nun die Klinke 13 um den Zapfen 14 nach oben, d.h.in Richtung des gerändelten Stabes bewegt wird, wird der Sperrschieber 7 entgegen dem Druck der Feder 8 nach oben bewegt, um den um Achse 5 schwenkbaren Bindehaken freizugeben.The
Dieser Freisetzungsvorgang ist in den Fig. 5 bis 7 mittels dreier verschiedener Phasen dargestellt. In diesen Figuren sind die zwei zu verbindenden Armierungseisen 15 und 16 sowie die zu verdrillenden Drähte in der Phase dargestellt, in welcher der Bindehaken und die Klinke in das obere Ende des Drahtformteils greifen. Dabei kann es sich um die Drahtschleife 17 gemäss Fig. 8, um Drahtbügel gemäss der eingangs erwähnten PCT-A-WO87/01753 handeln, wie noch weiter unten ausgeführt werden wird, oder um noch andere Drahtformteile. Die Verdrillung der Drähte, bzw. die Rotation des verdrillten Stabes wird durch einen Handgriff 20 verursacht, der hier nur symbolisch angedeutet ist und eine durchgehende Oeffnung aufweist, die dem Querschnitt des verdrillten Stabes angepasst ist. Infolge der Verdrillung wird die Klinke 13 nach oben gedrückt, um dann in eine etwa deckungsgleiche Stellung mit dem Bindehaken 4 zu gelangen. In der Stellung von Fig. 6 hat der Nockenteil 21 der Klinke 13 den Sperrschieber 7 aus den Einbuchtungen 6 gehoben, so dass beim weiteren Ziehen, d.h. beim Uebergang in die Stellung gemäss Fig. 7, der Bindehaken und die Klinke ausklinken und beim Weiterziehen in die Stellung Fig. 7 der Haken und die Klinke aus dem oberen Teil des Drahtformteiles schlüpft. In dieser Stellung drückt nun der Sperrschieber 7 auf das hintere Ende 22 des Bindehakens und bringt diesen sowie die Klinke 13 in die Ausgangsstellung gemäss Fig. 5 zurück.This release process is shown in FIGS. 5 to 7 using three different phases. In these figures, the two reinforcing
Durch diese automatische Auslösung des Bindehakens wird einerseits erreicht, dass die Drahtformteile stets gleich fest angezogen werden und andererseits vorallem, dass ein Reissen derselben durch zu heftiges und zu langes Ziehen verunmöglicht wird. Wie bereits eingangs erwähnt wurde, ist ein solches automatisches Ablösen der Drahtbügel besonders vorteilhaft, falls ein Verfahren und Vorrichtung zum Verbinden von mindestens zwei Stäben gemäss der PCT-A-WO87/01753 gewählt wird, denn dort ermöglicht das Verfahren und die Vorrichtung ein besonders schnelles Arbeiten auch von nicht spezialisierten Personen und ausserdem ist der Griffteil des Gerätes dort so gestaltet, dass relativ viel Kraft auf den verdrillten Stab ausgeübt wird, wodurch Gefahr bestehen kann, dass die Drähte reissen, was mit der vorliegenden Erfindung vermieden wird. Ausserdem eignen sich die dort beschriebenen Drahtbügel besonders gut, um die Klinke hochzuziehen und den Bindehaken auszulösen.This automatic release of the binding hook ensures that the wire parts are always be tightened equally and, on the other hand, above all that tearing them is made impossible by pulling them too hard and too long. As already mentioned at the beginning, such an automatic detachment of the wire brackets is particularly advantageous if a method and device for connecting at least two rods is selected in accordance with PCT-A-WO87 / 01753, because there the method and the device enable particularly fast Work even by non-specialized people and in addition the handle part of the device is designed there so that a relatively large amount of force is exerted on the twisted rod, which can lead to the risk of the wires breaking, which is avoided with the present invention. In addition, the wire brackets described there are particularly suitable for pulling up the pawl and releasing the binding hook.
Die vorliegende Erfindung eignet sich jedoch nicht nur für dieses Verfahren und Vorrichtung zum Verbinden von mindestens zwei Stäben, sondern auch für jede beliebige Vorrichtung zum Verdrillen von Drähten. Auf einem Bau gibt es Stellen, an denen ein einfaches herkömmliches Gerät zum Verdrillen vorteilhaft sein kann und für ein solches Gerät ist das erfindungsgemässe untere Ende der Verdrillvorrichtung ebenso geeignet.However, the present invention is suitable not only for this method and device for connecting at least two rods, but also for any device for twisting wires. There are places on a building where a simple conventional twisting device can be advantageous and the lower end of the twisting device according to the invention is also suitable for such a device.
Für ein solches einfaches Gerät sind die Drahtformteile 18 mit den Oesen 19 gemäss Fig. 9 bekannt, wobei jeweils in der Regel zwei davon aufs Mal verwendet werden, um die gewünschte Festigkeit zu erreichen. Zwecks Vereinfachung der Herstellung - vier Schweisspunkte, da zwei Formteile 18 verwendet werden müssen - und der Anwendung, bei der jeweils zwei Formteile auf einmal verwendet werden müssen, wurde die Einfachdrahtschleife 17 gemäss Fig. 8 geschaffen, die nur noch eine Schweissstelle 23 aufweist und wovon jeweils nur eine verwendet werden muss. Das doppelt U-förmige Biegen und einmalige Verschweissen der Drahtschleife 17 erfordert weniger komplexere Werkzeuge und wesentlich weniger Draht, wodurch die Produktionskosten nochmals herabgesetzt werden können. Um die Vorrichtung an verschiedene Draht-Formteile und Drahtsorten und -grössen anzupassen, kann es von Vorteil sein, entweder die Druckfeder auszuwechseln oder deren Spannung einzustellen.For such a simple device, the wire-shaped
Der Einsatz und die Ausbildung von Verdrill-Geräten ist nicht auf das Bauwesen beschränkt. In der Verpackungsindustrie oder im Rebbau werden ebenfalls Verdrill-Geräte eingesetzt, die mit dem oben beschriebenen Auslösemechanismus ausgestattet werden können.The use and training of twisting devices is not limited to the construction industry. In the packaging industry or in viticulture, twisting devices are also used, which can be equipped with the trigger mechanism described above.
