Definitions

  • the invention relates to a reinforcing mesh according to the preamble of claim 1 and a system for its production according to the preamble of claim 9.
  • Reinforcing gratings of the type mentioned at the outset are known, for example from DE-OS 2 402 653. These reinforcing gratings consist of wires running in the longitudinal direction, which are connected to wires running transversely thereto by welding. After welding, the reinforcement grid can be flattened using a rolling machine. Such a reinforcement grid is very complex to manufacture and therefore expensive. In addition, such a reinforcement grid is stiff, so that it can only be manufactured, transported and processed in straight lengths of a certain length.
  • the object of the invention is to further improve a reinforcement grid of the type mentioned at the outset and to provide a system for producing the reinforcement grid.
  • the reinforcing mesh is produced from a sheet metal strip, namely by making bevel cuts or slits and stretching the webs formed between the cuts or slits, results in a significant simplification of production without welding and thus without the risk of disadvantageous associated with welding Structural change.
  • sheet metal strips are easily procured as the starting material. Since the reinforcement grid is already made of sheet metal, rolling is generally not necessary and is in many cases even undesirable. As a result of the transverse stretching, the webs between the longitudinal strips twist transversely to the plane given by the longitudinal strips, as a result of which the toothing properties of the reinforcing mesh in the masonry joint are improved.
  • the system enables a particularly simple and economical production of the reinforcement grid, because with the special stretching station the tapes provided with bevel cuts and slots can be continuously and particularly easily and quickly stretched.
  • An embodiment according to claim 2 is expedient since the height of the webs can determine the thickness of the masonry joint to be produced.
  • the dimensions can be set as desired, starting with the thickness of the sheet metal strip, which can be 2 mm or more, for example, according to claim 3, and the choice of the width of the longitudinal strips and the webs.
  • the reinforcing grid can optionally be rolled up according to claim 4. It can then be produced in greater lengths, rolled up and transported and stored in the rolled-up state. At the construction site it is then only necessary to unwind the reinforcement grid from the roll and cut it to the desired length. This considerably simplifies the transport and storage as well as the handling of the reinforcement grid.
  • the reinforcement mesh may be appropriate to provide with a profile, preferably corrugation, in order to improve the anchoring of the reinforcement mesh in the masonry.
  • the stretching wheels of the stretching station can be provided with their own drive according to claim 10. However, an embodiment according to claim 11 is more advantageous.
  • the reinforcement grid coming from the stretching station is smoothed at least to a certain degree in a smoothing device according to claim 12 and can then optionally be profiled with the system according to claim 13.
  • FIG. 1 shows a sheet metal strip 2 of width c with cuts or slits 4 which run obliquely to the longitudinal direction and form webs 6 between them.
  • the two ends of the webs remain connected to the longitudinal strips 8, 10.
  • the width b of the webs in the sheet metal strip 2 later determine the height h of the webs 6 that are set up.
  • the width b or the height h can be set such that they correspond to the thickness of the masonry joint to be produced.
  • the raised webs which can protrude, for example, on both sides of the levels of the longitudinal strips 8, 10, improve the anchoring of the reinforcement grid in the mortar layer of the masonry joint.
  • the sheet metal strip necessary for the production of the reinforcement grid can have a thickness d of 2 or more mm and consist of a stainless steel, such as an inox steel.
  • FIGS. 4 and 5 show a further reinforcement grid, each of which has a row 18, 20 of webs 22, 24 between three longitudinal strips 12, 14, 16.
  • the webs 22, 24 are oriented in the same direction, while the webs 22a, 24a in FIG. 5 are directed in the opposite direction.
  • the webs of the individual rows can also be arranged offset from one another in a manner not shown.
  • the production of the reinforcement grid is extremely simple, since the sheet metal strip can be provided with the inclined cuts or slots on the one hand in successive working steps and on the other hand can be stretched laterally. If necessary, the reinforcement grid can be smoothed after stretching and / or with transverse to the longitudinal direction extending profiles, such as corrugations. The finished reinforcing mesh can then be rolled up if necessary. The reinforcement tape can be stored and transported in roll form. At the place of use, it is then only necessary to unwind and cut the necessary length of reinforcing mesh from the roll and to lay it on the masonry joint. Particularly when the reinforcement grid is profiled in the longitudinal direction and / or in the transverse direction, it is advantageous to cut the reinforcement grid to sections of the desired length immediately after manufacture and to combine the sections into a bundle that can be stored and transported.
  • Figures 6 to 8 show a particularly preferred system for producing such reinforcing mesh.
  • a sheet metal strip 2 is drawn off from a supply roll 26 and fed to a cutting station 28 which has two counter-acting cutting rolls 30, only one of which is shown, and which are driven by a drive 32.
  • the cutting rollers 30 have a known design and have cutting edges 34 which are used to produce the cuts or slots 4 from which the webs 6 are formed.
  • the sheet metal strip cut in this way is turned over deflection rollers 36, 38 and fed to a stretching station 40, which is equipped with stretching wheels 42, 44 and which are described in more detail below with reference to FIG. 7.
  • the stretching station is followed by a smoothing device 46, which can have, for example, two counteracting smooth rollers 48 and which presses the reinforcing grid coming from the stretching station 40, which is Z-shaped in cross section, more or less flat.
  • a subsequent profiling device 50 which, according to FIG. 8, has two gear wheels 52, 54 acting against one another, the reinforcement grid can again be provided with profiles 56 arranged transversely to the running direction, for example in the form of waves, in order to improve the adhesive or claw properties to improve the reinforcement grid for later use in masonry.
  • the profiling device 50 is followed by a pull-off device 58, which is equipped with a drive 60 in order to pull the reinforcement grid from the cutting station 28 through the system.
  • the separate extraction device 58 can also be omitted if the smoothing device 46 and / or the profiling device 50 are provided with a drive, so that they can take over the extraction function.
  • the reinforcing mesh produced is cut to the desired lengths and the reinforcing mesh sections 62 are combined to form a bundle 64 that can be transported and stored.
  • the special core of the system is the stretching station 40 with the stretching wheels 42, 44, as shown in FIG.
  • the stretching wheels have different diameters D1 and D2 and are arranged on two axially displaced axles 66, 68 such that the end faces 70, 72 of the stretching wheels 42, 44 on the inlet side 74 have the same surface lines.
  • the stretching wheels 42, 44 have an axial distance C which is greater than the thickness d of the sheet metal strip 2 to be processed.
  • the diameter difference D1 minus D2 of the two stretching wheels 42, 44 essentially corresponds to the distance a of the outer longitudinal strips 8, 10, 12 and 16 the reinforcing mesh of FIGS. 2, 4 and 5.
  • the stretching wheels are surrounded by a housing 76 which forms end-side guides 78, 80 which extend to the outlet side 82.
  • the radial distance A of the end faces 70, 72 of the stretching wheels 42, 44 from the associated end face guides 78, 80 is slightly larger than the thickness d of the sheet metal strip 2 to be processed.
  • the width B of the gap between the end faces 84, 86 and the end guides 78, 80 corresponds to the width c of the sheet metal strip to be processed.
  • the sheet metal strip to be processed runs into the stretching device on the inlet side 74 and is displaced by the staggered stretching wheels 42, 44 and their different ones Diameter D1, D2 stretched, the longitudinal strips 8, 10 remaining in the gaps between the end faces 84, 86 and the associated end face guides 78, 80 and being stretched from one another to such an extent that the web 6 in the gap between the stretching wheels 42, 44 on the Distance a is stretched.
  • the reinforcement grid has a Z-shaped shape and is therefore expediently smoothed in the smoothing device 46 to such an extent that it assumes the shape shown in FIGS. 2 to 5.
  • reinforcement grids can be produced so precisely and quickly, for example at a speed of one meter per second, that each order can be processed immediately and individually, and storage of prefabricated reinforcement grids becomes superfluous.
