Definitions

  • the invention relates to a method according to the introductory part of Claim 1.
  • the object of the invention is to eliminate these problems connected with stock control, supply and number of reinforcement wires, while at the same time eliminating problems in connection with the critical length of the reinforcement wires.
  • the invention is based on the idea of producing the reinforcement mats on site for slightly greater surfaces.
  • Reinforcement wire can be fed in cheaply, for example on rolls, and one direction of the surface can then be provided with pieces of parallel reinforcement wire.
  • the next step is to lay reinforcement wires in a direction at an angle to the first reinforcement wires. This angle will generally be 90°.
  • the mechanisation described means that lifting of the mats and unnecessary transportation thereof are completely superfluous, so that the disadvantages described above in connection with the state of the art are completely eliminated.
  • German Patent Specification 2,123,501 A number of parallel longitudinal wires are first provided from a supply. Starting from said supply, a wire end is gripped and placed by means of a change-over system in a corresponding guide tube. When, through pressing, the piece of wire is in the whole guide tube, it is cut off with a cutting device. The next thread is then pressed into a guide tube. Surrounding the wires by a guide means that it is not possible to use such a device for laying a reinforcement on site. Nor is the device according to the German patent intended for that purpose.
  • the first and the second reinforcement wires are provided touching each other.
  • various reinforcement wires are preferably removed from a supply, and conveyed and severed simultaneously.
  • supplies are provided at opposite sides of the surface for simultaneously laying adjoining reinforcement wires.
  • one or more reinforcement wires are fed in simultaneously, for example alternately, from the opposite sides.
  • supporting means for the reinforcement wires are provided on the surface before said reinforcement wires are laid.
  • the reinforcement must be at a certain height from the bottom of the surface.
  • the reinforcement wires are provided so that they cross each other essentially at right angles, and the supporting means are provided at an angle of essentially 45° relative to each of the reinforcement wires. In this way the supporting means do not impede the laying of the reinforcement wires.
  • the invention also relates to a supply device for reinforcement wire, comprising storage means for reinforcement wire, straightening means, pay-out means, conveying means for reinforcement wire and means for severing reinforcement wire.
  • the conveying means preferably comprise a circulating belt or cable connected to both conveyor devices, and provided at regular intervals with at least two fastening devices for reinforcement wires. This provides for a particularly simple conveyance of the reinforcement wires.
  • the straightening means are preferably in the form of straightening mechanisms rotating about the wire.
  • the invention also relates to supporting means for bearing reinforcement wires, comprising a base part resting on the ground and a bearing part for reinforcement wires some distance away.
  • the bearing part of the reinforcement wires is bounded here by at least one centring part.
  • Such supporting means can be made from a shaped part bent out of a piece of wire, which shaped part comprises the base part, the centring part and the intermediate connecting parts.
  • a further wire part, which forms the bearing part, can be fixed to the shaped part.
  • the base part is preferably provided here with an insulating material.
  • the supporting means are preferably provided in such a way that a further supporting part is present for bearing further reinforcement.
  • This further reinforcement can comprise top reinforcement.
  • Fig. 1 the surface to be provided with reinforcement wires is indicated in its entirety by 1 and comprises long sides 2 and short sides 3.
  • Supply devices 4 for wire are provided opposite each other at the long sides 2. They comprise, schematically shown, one or more rolls 5 of reinforcement wire driven by a motor 6, guide means 7, cutting means 8, and a conveying device 9.
  • Conveying device 9 comprises a belt 11 running around pulleys 10 and provided with fixing means 12 for schematically shown reinforcement wires 13.
  • Supply devices 4 are each controlled by a guide rail 14, which is provided with spacer lobes 15. Traction rolls 40 are present to move the wires coming off the rolls 5 through the straightening means 7.
  • Fig. 3 shows a detail of the straightening means 7 in longitudinal section. The inlet is indicated by 41 and the outlet by 42.
  • These straightening means comprise a drum 44 fixed rotatably by means of bearings 43 on the supply device 4.
  • drum 44 On drum 44 there are hydraulic pressure devices 45 which at the end are provided with an inset part of extremely hard material such as hard metal 46. In the most outward moved position parts 46 are situated past axis 47, so that the wire 13 moving through them is deformed.
  • drum 44 Near the outlet 42 drum 44 is provided with a drive pulley 48 for connection to a motor, which is not shown.
  • the device described above works as follows. Before a start is made on laying the reinforcement wires, supporting means 16 are first fitted, only parts of which are shown schematically, and which are described in greater detail with reference to Figures 4 and 5. Both devices 4 are fitted on the left side in Fig. 1, the top device 4 being moved to the right over a distance corresponding to at least the width of the surface taken up by the wires coming from the bottom supply device 4 in the drawing. The wires 13 are then unreeled by means of the motor 6 from reels 5, and guided through traction rolls 40, straightening means 7 and cutting means 8, and fixed to fixing means 12. This fixing can be carried out by any means known in the state of the art, for example by means of wedging.
  • Belt 11 is then set in rotation in such a way that the wires coming from the top supply device move downwards and the wires coming from the bottom supply device move upwards simultaneously (in the drawing, of course; in practice, the surface is essentially horizontal).
  • the wires are laid in such a way that they fall in the bearing parts 17 of the supporting means.
  • Supply devices 4 then move, guided by the rail 14, to the right over a distance which is determined by lobe 15. A large area of reinforcement wires can be laid extremely quickly in this way.
  • Fig. 4 illustrates an example of the supporting means described above.
  • These means comprise a bearing part 17, and it is shown schematically how two reinforcement wires 13 and 18 are laid on such a bearing part.
  • the supporting means 16 also have centring parts 20, by means of which the reinforcement wires 13 and 18 are pushed into the correct position.
  • the supporting means 16 rest on a base part 21 which can be provided with, for example, a plastic coating in order to meet the requirements of avoiding bimetallic corrosion.
  • the supporting means are made up of two parts: a part curved in a complex way, forming the base parts, the centring parts and the connecting parts lying between them, and a through wire 17 connected thereto and forming the bearing parts. These parts are fixed to each other, for example by welding.
  • Fig. 5 shows a further embodiment of the supporting means, which is indicated in its entirety by 23. Unlike the supporting means discussed with reference to Fig. 4, a nesting place 24 is provided here to bear a further top reinforcement.
