Definitions

  • the invention relates to a portable device for connecting reinforcing bars for use on construction sites.
  • Reinforcing bars also called reinforcing bars
  • 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. But this does not ensure the necessary tight and stable connection of the reinforcing bars 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.
  • the invention is therefore based on the object of being transportable Device for connecting reinforcing bars using known To develop functional groups that work with soft annealed steel wire and compensates for small differences in steel wire thickness and independently of the skills of a worker of consistently good quality Reinforcing iron connects.
  • the wire feed is designed so that soft annealed steel wire in the required length without deformation Loop formation and the twisting process can be supplied.
  • the Wire feed has two arranged as inclined rollers and with calibrated rollers driven in the same direction of rotation, using the steel wire Pull the motor support from the magazine and into the guide groove of the Lead loop former.
  • the steel wire is used according to the invention in such a strength that a tight and position-fixed connection of the crossing reinforcing bars is guaranteed. Compared to the previous state of the art significant advantage.
  • Other parts of the device according to the invention are a separating and twisting device, as well as the control of various functions over the necessary wire length.
  • the device according to the invention has two known pliers arms 1, 2, the pliers arm 1, which is designed in the manner of a hook in a known manner and is movable in the longitudinal direction with a slide bearing 4 on the casing 5, and the pliers arm 2 is fixed on the casing 5 is arranged.
  • a guide groove 3a or 3b for a steel wire 13 is incorporated in both gun arms.
  • a guide block 12 is attached to the inside of the jacket 5 in the region of the slide bearing 4 and connects with its guide groove 3c to the guide groove 3a of the pliers arm 2.
  • a separating device 10 is arranged opposite the guide block 12 on the outer surface of the casing 5.
  • the cutting device 10 works with a round knife M as a cutting tool, the round knife M pushing into a corresponding free space of the pliers arm 2 during the cutting process and cutting off the steel wire 13 when the opening 8 is reached.
  • a cylinder 6 is arranged in the middle of the casing 5 and is movable in the longitudinal direction.
  • the cylinder 6 carries pliers 7.
  • the pliers 7 can also be designed as a polyp pliers as a variant of the device.
  • a wire feed 11 is arranged outside the described device parts and essentially consists of two 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.
  • the tong arms 1, 2 are opened and the device is positioned over the crossing point of the reinforcing bars.
  • a switch (not shown) is triggered, the pliers arm 1 is brought up to the pliers arm 2 and the loop former is closed.
  • the guide groove 3c is thus connected "seamlessly" to the guide grooves 3a and 3b and the steel wire 13 is correctly looped around the crossing reinforcing bars.
  • the rollers 15 of the wire feed 11 are set in motion and the steel wire 13 is transported through the opening 8 and the guide block 12 into the guide grooves 3c, 3a, 3b until the steel wire 13 crosses its ends to reach the sensor 9.
  • Fig. 2 shows this situation.
  • the sensor 9 now releases the separating device 10, so that the circular knife M moves forward and the steel wire 13 cuts at the level of the opening 8, as shown in FIG. 3.
  • the pliers 7 close and clamp the ends of the steel wire 13.
  • the cylinder 6 then pushes over the closed pliers 7 and begins to rotate.
  • the rotation of the cylinder 6 takes place with a slight pre-tension, ie the cylinder 6 is pulled backwards during the rotational movement and a correct twisting of the ends of the steel wire 13 is thereby achieved.
  • 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 location.
  • the advancement of the steel wire 13 is guaranteed trouble-free via the wire feed 11 used according to the invention.
  • 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.
