Abstract

The wire twisting device has a twisted bar (1) with a binding hook (4) which is set in rotation when a gripping part is pulled. The binding hook can be swivelled about an axis (5) and is held in the normal position by a locking slide (7) engaging in indentations (6) in the binding hook. When pulling the wire loop around the binding hook, a latch (13) is lifted, by which means the locking slide and thus the binding hook are unlocked and swivelled, by which means it can slide out of the wire loop. <??>A device of this type allows a constant and optimum twisting of the wire without the risk of it tearing and permits the automatic pulling out of the binding hook in the same pulling movement. <??>The formed wire for tying reinforced iron bars is constructed as a single wire hoop (17) with a welding point (23). By this means, on the one hand its manufacture is simplified and material is saved and, on the other hand, a firm tying is guaranteed. <IMAGE>

Description

Die vorliegende Erfindung bezieht sich auf eine Vorrich­tung zum Verdrillen von Drähten, mit einem verdrillten Stab mit Bindehaken, der beim Ziehen eines Griffteils in Drehung versetzt wird und auf ein Draht-Formteil zum Ver­binden von Stäben, insbesondere Armierungseisenstäben.The present invention relates to a device for twisting wires, having a twisted rod with a binding hook which is set in rotation when a grip part is pulled, and a wire shaped part for connecting rods, in particular reinforcing iron rods.

Es sind eine Vielzahl von Vorrichtungen zum Verdrillen von Drähten bekannt sowie Drahtformteile, 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. Darüberhinaus erfordert die Herstellung der Drahtschlaufen mit zwei Ringen oder Oesen, die wie erwähnt in der Regel doppelt genommen werden müssen, einen relativen grossen Arbeitsaufwand und viel Material, was bei den benötigten grossen Mengen eine grosse Rolle spielt.A large number of devices for twisting wires are known, as are wire shaped parts for carrying out the fastening of reinforcing irons, this work being carried out mostly by specialists in chords. 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 at the top 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. It also requires the production of the wire loops with two rings or Eyes, which, as mentioned, usually have to be taken twice, a relatively large amount of work and a lot of material, which plays a major role in the large amounts required.

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 sowie ein Draht-Formteil, das leicht herzustellen ist, Material spart und eine sichere und feste Verbindung gewährleistet. Eine Vorrichtung und ein Formteil, die diese Aufgaben lösen, sind in den Ansprü­chen beschrieben.It is based on the object of the present invention to provide a device for twisting wires, which always ensures maximum attachment and an automatic release of the binding hook from the loop, and a wire molded part that is easy to manufacture, saves material and is safe and secure Connection guaranteed. A device and a molded part that solve these objects are 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.

Die Erfindung wird im folgenden anhand einer Zeichnung von Ausführungsbeispielen näher erläutert.

  • 2 shows a section along the line II-II of FIG. 1,
  • 3 shows a section along the line III-III of FIG. 1,

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 twisted rod 1 can be seen at the top, which is connected to a housing 3 via a rivet 2. With the previously known devices, the twisted rod simply merges into the binding hook. In the embodiment according to the invention, however, the binding hook 4 is articulated via an axis 5 to the lower part of the housing 3, as can be seen in particular from FIG. 4. As shown in 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.

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 legs 4a and 4b of the binding hook each have an indentation 6, into which a locking slide 7 engages. 3, this locking slide is T-shaped and is pressed into the indentations 6 by a compression spring 8. At this end, 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. The guide piece 10 is fastened in the housing 3, see FIG. 2. The lower edges 11 of the locking slide, which engage in the indentations 6, are only slightly broken in order to ensure a good locking.

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 locking slide 7 acts not only on the binding hook 4, but also on a pawl 13 which is rotatably arranged around a pin 14 and within the two legs 4a and 4b of the binding hook. If the pawl 13 is now moved upward around the pin 14, i.e. in the direction of the knurled rod, the locking slide 7 is moved upward against the pressure of the spring 8 in order to release the binding hook which can be pivoted about axis 5.

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 bars 15 and 16 to be connected and the wires to be twisted are shown in the phase in which the binding hook and the pawl engage in the upper end of the shaped wire part. This can be the wire loop 17 according to FIG. 8, wire hanger according to PCT-A-WO87 / 01753 mentioned at the outset, as will be explained further below, or other wire shaped parts. The twisting of the wires or the rotation of the twisted rod is caused by a handle 20, which is only indicated symbolically here and has a continuous opening which is adapted to the cross section of the twisted rod. As a result of the twisting, the pawl 13 is pressed upwards in order to then reach an approximately congruent position with the binding hook 4. In the position of FIG. 6, the cam part 21 of the pawl 13 has lifted the locking slide 7 out of the indentations 6, so that when it is pulled further, i. 7, release the binding hook and the pawl and, when moving on to the FIG. 7 position, the hook and the pawl slip out of the upper part of the shaped wire part. In this position, the locking slide 7 now presses on the rear end 22 of the binding hook and brings this and the pawl 13 back into the starting position according to FIG. 5.

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 shaped 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 device for twisting 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.The wire molded parts 18 with the eyelets 19 according to FIG. 9 are known for such a simple device, two of which are generally used at a time in order to achieve the desired strength. In order to simplify the production - four welding points, since two molded parts 18 have to be used - and the application, in which two molded parts have to be used at a time, the single wire loop 17 according to FIG. 8 was created, which only has one welding point 23 and of which only one must be used at a time. The double U-shaped bending and one-time welding of the wire loop 17 requires less complex tools and significantly less wire, which means that the production costs can be reduced again. In order to adapt the device to different wire shaped parts and wire types and sizes, it can be advantageous to either replace the compression spring or to adjust its tension.

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 und die erfindungs­gemässe Drahtschleife kann dort auch eingesetzt werden.The use and training of twisting devices is not limited to the construction industry. In the packaging industry or in vine growing, twisting devices are also used which can be equipped with the trigger mechanism described above and the wire loop according to the invention can also be used there.
