Description

Die Erfindung betrifft eine transportable Vorrichtung zum Verbinden von Bewehrungseisen zur Verwendung auf Baustellen. Bewehrungseisen, auch Moniereisen oder Armierungsstäbe genannt, dienen bei der Herstellung von Stahlbetonbauten als Einlagen. Zum Verbinden und Fixieren der Bewehrungseisen sind aus dem Stand der Technik bereits verschiedene Werkzeuge bzw. Vorrichtungen bekannt. Allen gemeinsam ist die Verwendung von geglühtem Stahldraht und die Anordnung von Drahtmagazin, Klemmeinrichtung, Schneide- und Verdrilleinrichtung. Aus DE-OS 36 03 752 ist eine transportable Vorrichtung zum Verbinden von Bewehrungseisen bekannt, die die Kombination eines Stahldraht-Abgabemechanismus, einen Mechanismus für die Stahldrahtschleifenbildung, die Stahldrahtabtrennung und die Stahldrahtverdrillung beschreibt. Die offenbarte Vorrichtung ermöglicht eine schrittweise Zuführung vorgegebener Stahldrahtlängen. Nachteilig an dieser Vorrichtung ist, daß härterer Stahldraht zum Einsatz kommen muß, als bisher bei manueller Arbeitsweise eingesetzt werden kann, da Stahldraht in bisher üblicher Härte nicht verformungsfrei transportiert werden kann. Nur dadurch ist die erforderlich enge und stabile Verbindung der Bewehrungseisen durch Verdrillung der Stahldrähte mit dieser Vorrichtung nicht gesichert werden. Der Transportmechanismus, wie er in DE-OS 36 03 752 beschrieben ist, kann auch kleine Unregelmäßigkeiten in der Stahldrahtstärke, die produktionsbedingt auftreten, nicht kompensieren und dadurch bedingte Stockungen während des Verdrillens nicht ausschließen.The invention relates to a portable device for connecting reinforcing bars for use on construction sites. Reinforcing bars, also called reinforcing bars, are used as inserts in the manufacture of reinforced concrete structures. Various tools and devices for connecting and fixing the reinforcing bars are already known from the prior art. Common to all is the use of annealed steel wire and the arrangement of wire magazine, clamping device, cutting and twisting device. From DE-OS 36 03 752 a transportable device for connecting reinforcing bars is known, which describes the combination of a steel wire delivery mechanism, a mechanism for steel wire loop formation, the steel wire separation and the steel wire twisting. The disclosed device enables a stepwise supply of predetermined lengths of steel wire. A disadvantage of this device is that harder steel wire has to be used than has previously been possible with manual operation, since steel wire cannot be transported without deformation in the hardness that has hitherto been customary. This is the only way to ensure that the necessary tight and stable connection of the reinforcement bars is not ensured by twisting the steel wires with this device. The transport mechanism , as described in DE-OS 36 03 752, cannot compensate even small irregularities in the steel wire thickness, which occur due to production, and therefore cannot rule out any stagnation during twisting.

Der Erfindung liegt somit die Aufgabe zugrunde, eine transportable Vorrichtung zum Verbinden von Bewehrungseisen unter Nutzung bekannter Funktionsgruppen zu entwickeln, die mit weichgeglühtem Stahldraht arbeitet und geringe Unterschiede in der Stahldrahtstärke ausgleicht und unabhängig von den Fertigkeiten einer Arbeitskraft mit gleichbleibend guter Qualität die Bewehrungseisen verbindet.The invention is therefore based on the object of developing a transportable device for connecting reinforcing bars using known functional groups, which works with soft-annealed steel wire and compensates for small differences in steel wire thickness and independently of the skills of a worker with consistently good quality that connects reinforcing bars.

Erfindungsgemäß wird die Aufgabe mit den kennzeichnenden Merkmalen des Hauptanspruches gelöst. Dabei ist die Drahtzuführung so ausgebildet, daß weichgeglühter Stahldraht verformungsfrei in der erforderlichen Länge zur Schleifenbildung und dem Verdrillungsprozeß zugeführt werden kann. Die Drahtzuführung hat zwei nach dem Schrägrollenprinzip angeordnete und mit gleicher Drehrichtung angetriebene kalibrierte Rollen, die den Stahldraht mit Motorunterstützung vom Magazin abziehen und in die Führungsnut des Schleifenbildners führen. Mit der Anwendung des Schrägrollenprinzips ist weicher Stahldraht verformungsfrei und sicher transportierbar, wobei während der Vorwärtsbewegung des Stahldrahtes die schräg angeordneten kalibrierten Rollen den Stahldraht an der Oberfläche kalt vergüten, dadurch steuerbar machen und die vorhandenen feinen, aber nachteiligen, Unterschiede in der Stahldrahtstärke ausgleichen. Der Stahldraht wird erfindungsgemäß in solcher Stärke verwendet, daß eine enge und positionsfixierte Verbindung der sich kreuzenden Bewehrungseisen gewährleistet ist. Das ist gegenüber dem bisherigen Stand der Technik ein wesentlicher Vorteil. Weitere Teile der erfindungsgemäßen Vorrichtung sind eine Abtrenn- und Verdrilleinrichtung, sowie die Steuerung der verschiedenen Funktionen über die notwendige Drahtlänge.According to the invention the object is achieved with the characterizing features of the main claim. The wire feed is designed so that soft-annealed steel wire can be fed without deformation in the required length for loop formation and the twisting process. The wire feed has two calibrated rollers arranged according to the inclined roller principle and driven in the same direction of rotation, which pull the steel wire with motor support from the magazine and guide it into the guide groove of the loop former. With the use of the inclined roller principle, soft steel wire can be transported safely and without deformation, while during the forward movement of the steel wire the diagonally arranged, calibrated rollers cold temper the steel wire on the surface, thereby making it controllable and compensating for the existing fine, but disadvantageous, differences in the steel wire thickness. The steel wire is used according to the invention in such a strength that a tight and positionally fixed connection of the crossing reinforcing bars is ensured. This is a significant advantage over the prior art. Further parts of the device according to the invention are a separating and twisting device, as well as the control of the various functions over the necessary wire length.

Wie aus Fig.1 ersichtlich, weist die erfindungsgemäße Vorrichtung zwei bekannte Zangenarme 1,2 auf, wobei Zangenarm 1, in bekannterweise hakenförmig ausgebildet und in Längsrichtung beweglich mit Gleitlager 4 am Mantel 5 angeordnet ist und Zangenarm 2 am Mantel 5 fest angeordent ist. In bekannter Weise ist in beiden Zangenarmen eine Führungsnut 3a bzw. 3b für Stahldraht 13 eingearbeitet. Zur besseren Führung von Stahldraht 13 ist auf der Innenseite von Mantel 5 im Bereich von Gleitlager 4 Führungsklotz 12, der mit seiner Führungsnut 3c an Führungsnut 3a von Zangenarm 2 anschließt, angesetzt. Gegenüber von Führungsklotz 12 ist an der Außenfläche von Mantel 5 Trenneinrichtung 10 angeordnet. Trenneinrichtung 10 arbeitet mit einem Rundmesser M als Schneidewerkzeug, wobei das Rundmesser M in einen entsprechenden Freiraum des Zangenarmes 2 beim Trennvorgang hineinstößt und bei Erreichen von Öffnung 8 Stahldraht 13 abtrennt. In den hinteren Bereich des Mantel 5 ragt Sensor 9, der steuermäßig mit der Trenneinrichtung 10 verbunden ist. Mittig im Mantel 5 ist Zylinder 6 angeordnet, der in Längsrichtung beweglich ist. Zylinder 6 trägt Zange 7. Zange 7 kann als eine Variante der Vorrichtung auch als Polypenzange ausgebildet sein. Außerhalb der beschriebenen Vorrichtungsteile ist die Drahtzuführung 11 angeordnet, die im wesentlichen aus 2 hintereinander in Schrägrollenanordnung und mit gleicher Drehrichtung angetriebenen kalibrierten Rollen 15 besteht. Nicht dargestellt ist der Antriebsmotor für die Rollen 15. In der Ausgangsposition der Vorrichtung sind die Zangenarme 1,2 geöffnet und die Vorrichtung wird über der Kreuzungsstelle der Bewehrungseisen positioniert. Mit der Auslösung eines nicht dargestelltem Schalters wird Zangenarm 1 an Zangenarm 2 herangeführt und der Schleifenbildner geschlossen. Damit ist Führungsnut 3c mit 3a und 3b "nahtlos" verbunden und Stahldraht 13 wird korrekt zur Schleife um die sich kreuzenden Bewehrungseisen gelegt. Die Rollen 15 von Drahtzuführung 11 werden in Bewegung versetzt und Stahldraht 13 wird, durch Öffnung 8 und Führungsklotz 12 in Führungsnut 3c, 3a, 3b bis Stahldraht 13 seine Enden überkreuzend Sensor 9 erreicht, transportiert. Diese Situation zeigt Fig.2. Sensor 9 lößt nun Trenneinrichtung 10 aus, so daß sich das Rundmesser M nach vorn bewegt und Stahldraht 13 in Höhe von Öffnung 8 zerschneidet, wie Fig. 3 zeigt. Gleichzeitig schließt sich Zange 7 und verklemmt die Enden von Stahldraht 13. Anschließend schiebt sich Zylinder 6 über die geschlossene Zange 7 und beginnt zu rotieren. Die Rotation von Zylinder 6 erfolgt unter leichter Vorspannung, d.h. Zylinder 6 wird während der Rotationsbewegung nach hinten gezogen und dadurch eine korrekte Verdrillung der Enden des Stahldrahtes 13 erreicht. Nach erfahrungsgemäß dichter Verdrillung wird die Rotation des Zylinders 6 abgeschalten, die Zangenarme 1,2 fahren auseinander, die erfindungsgemäße Vorrichtung wird von den nunmehr miteinander verdrillten Bewehrungseisen entfernt und wird an anderer Stelle erneut eingesetzt.
Der Vorschub von Stahldraht 13 ist störungsfrei über die erfindungsgemäß eingesetzte Drahtzuführung 11 gewährleistet. Mit weichem, leicht verformbarem Stahldraht 13 ist eine sehr enge Verbindung und Fixierung der Kreuzungsstelle der Bewehrungseisen gesichert und gegenüber dem bekannten Stand der Technik das vereinfachte Handling begründet.As can be seen from FIG. 1, the device according to the invention has two known gun arms 1, 2, gun arm 1, which is known to be hook-shaped and is movable in the longitudinal direction with slide bearing 4 on the jacket 5, and gun arm 2 is fixedly arranged on the jacket 5. In a known manner, a guide groove 3a or 3b for steel wire 13 is incorporated in both gun arms. For better guidance of steel wire 13, guide block 12, which connects with its guide groove 3c to guide groove 3a of pliers arm 2, is attached to the inside of jacket 5 in the region of slide bearing 4. Opposite guide block 12, separating device 10 is arranged on the outer surface of jacket 5. Cutting device 10 works with a circular knife M as a cutting tool, the circular knife M pushing into a corresponding free space of the pliers arm 2 during the cutting process and cutting off steel wire 13 when opening 8 is reached. Sensor 9, which is connected to the separating device 10 in terms of control, protrudes into the rear area of the jacket 5. Cylinder 6, which is movable in the longitudinal direction, is arranged in the middle of the jacket 5. Cylinder 6 carries pliers 7. Pliers 7 can also be designed as polyp pliers as a variant of the device. Outside of the described device parts, the wire feed 11 is arranged, which essentially consists of 2 calibrated rollers 15 driven one behind the other in an inclined roller arrangement and with the same direction of rotation. The drive motor for the rollers 15 is not shown. In the starting position of the device, the tong arms 1, 2 are opened and the device is positioned over the crossing point of the reinforcing bars. When a switch (not shown) is triggered, the pliers arm 1 is brought up to the pliers arm 2 and the loop former is closed. In this way, the guide groove 3c is connected "seamlessly" to 3a and 3b and steel wire 13 is correctly looped around the crossing reinforcing bars. The rolls 15 of wire feed 11 are set in motion and steel wire 13 is transported through opening 8 and guide block 12 in guide groove 3c, 3a, 3b until steel wire 13 reaches its ends crossing sensor 9. Fig. 2 shows this situation. Sensor 9 now triggers separating device 10, so that the circular knife M moves forward and cuts steel wire 13 at the height of opening 8, as shown in FIG. 3. At the same time, pliers 7 close and clamp the ends of steel wire 13. Subsequently, cylinder 6 slides over the closed pliers 7 and begins to rotate. The rotation of cylinder 6 takes place with a slight pre-tension, ie cylinder 6 is pulled backwards during the rotational movement and a correct twisting of the ends of the steel wire 13 is thereby achieved. After experience has shown that the twist is tight, the rotation of the cylinder 6 is switched off, the tong arms 1, 2 move apart, the device according to the invention is removed from the reinforcing bars, which are now twisted together, and is used again at another point.
The feed of steel wire 13 is ensured without interference via the wire feed 11 used according to the invention. With soft, easily deformable steel wire 13, a very close connection and fixation of the crossing point of the reinforcing bars is ensured and the simplified handling is justified compared to the known prior art.
