Definitions

  • the invention relates to methods for producing a bundle of reinforcing bars according to the preamble of claim 1 or 3.
  • the reinforcing bars can have the same or different diameters, depending on the overall cross-section to be achieved or on the wires available.
  • the invention further relates to a device according to the preamble of claim 6, by means of which the method can be carried out.
  • Reinforcement bundles produced by such a method can be found, for example, in AT-B-230 074. It is proposed to produce reinforcement elements with larger cross-sections by bundling at least three equally long, contacting reinforcing bars, with a connection of the bars being provided at least in some places.
  • the bundling of single rods of the same length has various advantages: surface enlargement, increased buckling strength, more favorable moment of inertia and resistance, restriction to a few diameters and, as a replacement for rods with large diameters, also lower production costs, as these have considerable price surcharges compared to rods of the medium diameter range . The latter advantage is particularly evident in reinforcing bars with high steel quality.
  • the invention also relates to a device according to the preamble of patent claim 6.
  • the bars required for the manufacture of the reinforcement bundles described there can be pulled off the roll as wires, this activity usually being carried out is supported by feed devices. The cut bars are then welded, soldered or bound.
  • straight rod pieces of the required lengths and diameters are bundled individually in order to save working time at least when laying.
  • the invention has now set itself the task of creating methods and a simple, rationally usable device for producing reinforcement bundles of any number of bars and any diameter, in which the diameter of the bars are the same or different, and in all cases their lengths to the course can be adapted to the bending moment line.
  • bundles of two, three or four rods of the same and different diameters and the same or different lengths should be able to be produced in a single automatic production system without significant downtimes, the overall system, in particular the number of reels, being economically justifiable Requirement for reinforcement bundles about adjusted dimensions moved.
  • Claim 6 indicates a device that can be used to carry out any of the methods mentioned.
  • all reinforcement wires are constantly available in the device, of which only those are selected and processed which are required for the bundle of reinforcement that is currently to be produced. If, for example, two-bar reinforcement bundles are required, two of the reinforcement wires inserted into the selection device can be detected and welded to one another. The changeover to the production of three-bar bundles is therefore limited to the activation of another existing reinforcement wire, which is integrated into the processing process. To produce a four-bar bundle, a fourth reinforcing bar, which is at rest in the selection device, is included in the production.
  • a device with four reinforcement wires of the same thickness is therefore already able to produce three different types of bundles with bars of the same length in any length. If the reinforcement bundles are to be approximated to the torque curve, the individually controllable feed devices are activated at different times and, when the wires are cut off at the same time, shut down in reverse order. The device is then able to produce two-, three-, or four-bar bundles of any length, the bar lengths being adapted to the torque curve from bundle to bundle and therefore being different.
  • the number of different bundles that can be produced can also be increased if all reinforcement bars in the bundle have different diameters. For example, with four reinforcement wires in successive diameters, three different two-bar bundles, two different three-bar bundles and one four-bar bundle, i.e. a total of six different types of bundles, each in any length adapted to the course of the moment, can be produced if the reinforcement wires each have successive diameters be combined. If the diameters are combined in any way, six different two-bar, four three-bar and one four-bar, i.e. a total of eleven different bundles can be produced, each in any length. The resulting advantage is multiplied particularly when the number of reels is increased.
  • reinforcement bundles can be produced that can replace all the usual single bars, whereby the size of the stock part is less than the usual width of mesh welding machines.
  • the device which is characterized in claim 9, significantly fewer individually controlled feed devices are required because they can be adjusted together between the individual positions. If, for example, the production of a maximum of four-bar bundles is planned, four feed devices are provided in the feed block, each of which in turn can be driven individually in order to also be able to produce two- and three-bar bundles.
  • the displacement paths of the feed blocks to the horizontal each include half the angle of the two tangential planes.
  • the 1 is equipped with a storage part 1, in which twelve reels for reinforcing wires 5 to 16, each of which has a different diameter, are arranged in two rows.
  • the reinforcement wires 5-16 for example, each have a different diameter by 1 mm, increasing from 5 mm, and correspond to the common reinforcement wires that can be wound on reels.
  • Each reel is marked with an unspecified or shown usual balance swing arm and a spring-loaded brake, which is released when the balance swing arm is actuated.
  • the reels for the reinforcement wires with a diameter from 12 mm, i.e. for the wires 12-16, are additionally equipped with a hydraulic driver.
  • the reinforcement wire 5-16 is guided through a separate straightening device 18 to the selection unit 2, into which the ends of the reinforcement wires 5-16 protrude.
  • the selection unit 2 is assigned a feed unit 3, which has a plurality of feed devices 19, 20, each consisting of a drive roller 19 and a pinch roller 20, each of which, individually controlled, can move one of the ends of the reinforcing wires 5-16 projecting into the selection unit (Fig. 2, 3).
  • a cutting unit 17 which consists of the maximum number of rods of the bundle corresponding, individually controlled scissors. The design of these scissors corresponds essentially to that used in the manufacture of lattice girders or structural steel mats, and is therefore not shown in detail.
  • the cutting unit 17 is followed by a welding unit 4, which combines the rods into bundles and ejects them at the end of the device.
  • the direction of work corresponds to arrow A.
  • the number of reels and thus the reinforcement wires 5-16 in the illustrated embodiment is three times the maximum number of bars to be bundled. Generally it is at least one bigger. This means that more and more reinforcement wires 5-16 are available in the selection device 2 than are required for the production of a bundle.
  • the number and the diameter of the reinforcing wires 5-16 can therefore be selected with the aid of the feed devices 19, 20.
  • twelve reinforcement wires 5-16 are shown, the ends of which protrude into the selection unit 2.
  • a feed device 19, 20 is assigned to each of these reinforcement wires, the drive shafts 21 of the drive rollers 19 being individually drivable.
  • the reinforcing wires 5-16 are - starting from the left in the drawing - arranged in one plane with increasing diameter. Since bars with adjacent diameters are usually bundled, for example to produce a bundle according to FIG. 4, the feed devices are set in motion, between which the reinforcement wires 7, 8, 9 are clamped. If the bundle of staggered bars according to FIG. 6 is to approach the course of the bending moment, the feed device assigned to the reinforcement wire 8 begins with the feed.
  • the feed device assigned to the reinforcement wire 7 and finally the feed device assigned to the reinforcement wire 9 are set in motion, all feed devices 19, 20 running at the same speeds, in particular in the cycle method.
  • the reinforcement wires reaching welding unit 4 in this way are welded to one another at least in some places.
  • the advance of the reinforcement wire 9 is stopped and at the same time cut off by a pair of scissors of the cutting unit 17 assigned to it.
  • the feed of the wires 7 and 8 continues, as does the welding.
  • the feed of the wire 7 is stopped as soon as its pre-calculated length is reached, and another pair of scissors assigned to it cuts it off.
  • the advancement of the wire 8 is continued up to the total length of the bundle, missing welds being carried out.
  • the reinforcement wire 8 is also cut by another, individually controlled scissors and the finished bundle is ejected from the device.
  • the procedure for producing a bundle according to FIG. 5 is the same, except that a total of four reinforcement wires 7, 8, 9, 10 are processed.
  • This version is also suitable for bundling non-adjacent reinforcement wires, since any feed device can be set in motion by the individual control.
  • the feed unit shown in FIG. 3 shows three feed devices 19, 20, which are combined in two feed blocks 22.
  • This feed unit can be used for production systems in which only two- or three-bar bundles are to be produced, in which adjacent diameters are used.
  • each feed block 22 is equipped with four rollers, so that four feed devices 19, 20 can be used.
  • the reinforcing wires 5-16 are in turn arranged with increasing diameter in the selection unit 2, starting from the left, the common center plane running horizontally.
  • the reinforcement wires 5-16 are aligned so that they have two common tangential planes that enclose the angle a with each other.
  • Each feed block 22 is displaceable in the direction of arrow B on a guide track 23 which is height-adjustable in the direction of arrow C, each guide track 23 running parallel to a tangential plane and therefore including the angle with the horizontal.
  • the feed devices 19, 20 therefore each grip a group of adjacent reinforcement wires 5-16, with the inclined guideways 23 not requiring any adaptation to the different diameters of the reinforcement wires.
  • the drive rollers 19 of the feed devices can in turn be driven individually, so that any combination of reinforcement wires is again possible within each group.
  • the guideways 23 are moved apart, the front thrust blocks 22 moved to the desired location and the guideways 23 approximated again, whereupon the feed of the modified group of reinforcing wires can be started in the manner described in FIG. 2.
  • the method according to the invention enables the automatic production of reinforcement bundles in a large number of different combinations of bars, lengths and bars, without the need for time-consuming changes to the system.
  • the system is advantageously controlled by means of electronic data processing, by means of which the reinforcement wires are automatically selected, the feed devices assigned to these selected wires are used, and the shears of the cutting unit assigned to the selected wires are used.
  • the preferred embodiment of the invention in which only reinforcement wires with different diameters are used, provides a further advantage of great importance.
  • about a third of the total reinforcement runs up to the support, since the reinforcement wire 8 with the middle cross section is the longest. If a higher proportion is required, wire 9 becomes necessary, if a lower proportion is required, wire 7 is provided along the entire length and the others are shortened.
