Definitions

  • the invention relates to a method for producing a reinforcement element consisting of parallel longitudinal reinforcement bars and transverse bars distributed along these, into which at least one additional bar is welded and parallel to the longitudinal reinforcement bars, in order to adapt the overall cross section of the longitudinal reinforcement to the torque curve of a reinforced concrete component that is mainly subjected to bending
  • Longitudinal reinforcement wires drawn from reels are fed to an automatic production system and continuously welded in this at regular work cycles, with at least one additional reinforcement wire also being pulled from a reel and welded in as an additional bar in the position and length that covers the moment, whereupon the reinforcement element is cut off.
  • the invention has now set itself the task of refining the method of the type mentioned in such a way that the additional reinforcement wires, despite their length and arrangement determined by the course of the moment, can be incorporated uncut into the intermittent, continuous workflow, with a welding point at each end of the additional rod being produced given is.
  • each additional reinforcement wire the feed path of which during its welding is equated to the same feed path of the longitudinal reinforcement wires in each work cycle, is cut behind the torque-related last welding point and thus the feed is interrupted, whereupon the additional reinforcement wire during the up to The next welding cycle following work cycles, whenever its torque-related or welding-related length is greater than an integer multiple of the feed path, is shifted by the difference amount by a separately controllable feed device.
  • Each additional reinforcement bar can be welded to the cross wires in accordance with the known prior art.
  • the distance between two cross wires corresponds to an integer multiple of the feed path per cycle, preferably the simple feed path.
  • the weld-related length of the additional rod is often somewhat greater than the torque-related length and always greater than an integral multiple of the feed path. This results in the need to advance the additional reinforcement wire during its rest period by the sum of the two welding-related protrusions so that the end of the reinforcement wire lying behind a cross wire after cutting is in front of a cross wire at the beginning of the next welding phase.
  • the extent of the separate, out-of-phase feed is the sum of the two welding-related projections.
  • each additional rod must only have the length due to torque, so that its ends can be located anywhere.
  • at least one movable welding electrode pair must be provided, which is coordinated with the separately controllable feed device, and which is moved into the respective end position during the rest phase of the additional reinforcement wire .
  • the pair of welding electrodes welds the additional reinforcement wire in time with the production system, but between the first and the last welding the electrode pair is shifted back by the difference, so that the last welding point is at the end of the additional rod.
  • a preferred embodiment provides that the additional reinforcement wire is welded on by means of two pairs of welding electrodes, of which the front pair of welding electrodes is covered by a first part of the difference ges in the position of the front end, and the rear welding electrode pair is shifted back by the remaining part of the difference, the welding being carried out approximately to the middle of the torque-related length of the additional rod from the front and the remaining welds from the rear welding electrode pair.
  • the two parts of the difference are of the same size, so that the displacement movement can be coupled.
  • the front electrode pair moves forward by half the difference and, via the coupling, shifts the rear electrode pair, which is preferably spaced from the front electrode pair by the feed path per work cycle, by half the difference. In this way, a symmetrical welding point distribution on the additional rod is achieved, the only larger welding point distance appearing in the center of the additional rod in which the lowest force transfer stress is to be absorbed.
  • the separately controllable feed of the additional reinforcement wire is preferably carried out at the same speed as the regular feed during a work cycle, so that it is already completed before the end of the work cycle.
  • every work cycle can be selected for the special feed during the rest of the reinforcement wire, but it has been shown that the last work cycle of the rest is the cheapest.
  • the difference in all previous versions corresponds to the amount between the torque or welding-related length and the smaller integer multiple of the regular feed path.
  • the reinforcement elements to be produced can be of any type, i. H. Lattice girders with bow-like crossbars or bow-shaped coils, reinforcement mats or mat-like reinforcement elements, into which a lattice girder is integrated, the additional bars preferably reinforcing the lower flange bars of the integrated girder.
  • Appropriate control with electronic data processing makes it easy to manufacture the reinforcement elements in different lengths at the right moment, since only the special feed and the cutting device for the additional reinforcement wire, as well as the cutting device for separating the finished elements, have to be adapted to the respective situation.
  • a reinforced concrete component A supported by support B according to FIG. 1 has, for the sake of clarity, a reinforcement element 10, shown only schematically and in plan view, with reinforcing bars 11, 13, which are arranged in the tensile zone of the reinforced concrete component A.
  • the additional bars 13 are reduced in length in accordance with the moments M decreasing against the supports B, so that reinforcing steel is saved. In order to be able to dispense with end anchoring means, the forces acting on the shorter additional bars 13 are each completely introduced into the next longer additional bar 13 or the longitudinal reinforcement bar 11.
  • a reinforcement element 10 in the form of a lattice girder corresponding to the schematic representation according to FIG. 1 is shown in FIG. 2. It has an upper chord formed by a longitudinal reinforcement bar 11, a lower chord formed by two longitudinal reinforcement bars 11 and a series of transverse bars 12 connecting these, which are formed by loop coils.
  • the bottom chord reinforcement also has a shorter additional bar 13 in addition to each longitudinal bar 11 that is continuous over the entire length. The length and the arrangement of each additional bar 13 are selected so that a bottom chord reinforcement adapted to the torque curve is formed.
  • Each additional rod 13 ends with a welding-related projection on a cross rod 12.
  • FIG. 3 A further example of a reinforcement element 10, the reinforcement bars of which are cut to match a torque curve, is shown in FIG. 3, in which a reinforcement mat is shown.
  • Two longitudinal reinforcement bars 11 are reinforced by shorter additional bars 13 which are welded directly to the longitudinal reinforcement bars 11.
  • Each end of an additional rod 13 does not coincide with a cross rod 12 of the mat, so that the additional rods 13 according to this embodiment have only the length due to torque.
  • the longitudinal reinforcement wires 1 are drawn off from reels (not shown), then preferably pass through a straightening unit and enter the welding line. For the sake of clarity, only three of the longitudinal reinforcement wires 1 are shown in FIG. 4.
  • the cross wires, which are formed for the lattice girder production according to FIG. 2 by loop coils, are also pulled from reels, formed into loop coils and welded to the longitudinal reinforcement bars 1. In this case, the lines designated by 2 in FIG. 4 represent the center lines of the loops.
  • the cross wires 2 can be cut to length in the system or can already be cut to length.
  • the automatic production system welds the wires 1 and 2 into endless reinforcement structures in regular, continuous work cycles, the feed path per work cycle being designated by a.
  • the distance between two transverse wires 2 is an integral multiple of the feed path a, preferably the simple feed path. However, it can also be 2a or 3a, or vary over the length of the reinforcement element that is created.
  • the torque curve M (FIG. 1) required, of which only one is shown in FIG. 4 for the sake of clarity, and which do not appear to be continuously fed in the endless reinforcement structure
  • the regular clocked workflow as uncut To be able to insert reinforcement wires 3, although their length due to torque or welding generally does not correspond to an integral multiple of the regular feed path a, the procedure is as follows.
  • reinforcement wires 1 and cross wires 2 are connected for a few work cycles. After a certain number of cycles, which depends on the length of the reinforcement element 10 to be produced and the torque-related or welding-related length b of the additional rod 13, the front end of each additional reinforcement wire 3 is incorporated into the regular sequence and welded in at intervals. According to the number of cycles or welds corresponding to the length b, each reinforcement wire 3 is cut immediately after the last welding part. This means an interruption of the regular feed of each additional reinforcement wire 3.
  • the additional joints 13 welded in this way are arranged in the reinforcement element 10 to cover the moment as soon as it is separated along the dash-dotted line in FIG. 4 when leaving the system.
  • the additional bars 13 are further provided that they are welded to cross bars 12 by the projections c 1 , C2 , so that the length b due to welding in this case, which must be greater than the length due to torque, results from an integral multiple plus the projections C. 1 , c 2 composed.
  • each reinforcement wire 3 interrupted in the feed is due to the cut behind a cross wire 2, after each cycle of the work process at the same distance from a cross wire 2 and can therefore not be welded to a cross wire 2 at its end to form the next additional bar. It is therefore detected during its rest by a separate, controlled feed device and advanced by the difference d, which results from the torque or welding-related length b minus the integer multiple, so that it again has the welding-related projection C1 as soon as it enters the regular workflow is incorporated (see left part of Fig. 4).
  • each additional reinforcement wire 3 is not welded to a transverse wire 2, but to a longitudinal reinforcement wire 1, the length b is exclusively torque-related, since the end of the additional wire 3 can be welded at any point.
  • the torque-related length b does not correspond to an integral multiple of the feed path a, a separate displacement of the additional reinforcement wire 3 is necessary during its standstill, since the reinstallation of the wire 3 is to achieve its current position. Since the boundary lines of the double arrow a, or their parallels in FIG. 4, represent the cycle and feed steps, even with an exclusively torque-related length b, which is not on, there are overhangs C 1 ' C2 , which together form the difference d .
  • two pairs of electrodes are provided, both of which are movable, said one pair by a portion C1 of the difference d to the front and the other c around a portion is shifted 2 to the rear, and the two pairs of electrodes each carry half of the welds, so that the by the difference d increased distance a between two welding points comes to lie in the middle of the additional rod 13.
  • the special feed of the additional reinforcement wire 3 by the difference d is also its negative feed, that is the return drawing conceivable, in which case the difference to the larger integer multiple of the regular feed path a is decisive, which amounts to a minus d.
