Definitions

  • the present invention relates to a spacer for a lower or outer reinforcement according to the preamble of claim 1 and to a method for its production.
  • spacers for reinforcement also for lower or outer reinforcement
  • not only entire reinforcements are laid, but individual reinforcement bars that should be spaced as evenly as possible.
  • the spacer according to the invention consists of a number of brackets 1, which are welded to a longitudinal wire 2.
  • Plastic feet 4 are attached to both ends 3 of the brackets, which prevent injury to the base and give a larger contact surface. If the reinforcement bars have to be placed on insulation or on non-load-bearing supports, plates can be attached to the feet.
  • the apex of the bracket has an indentation 6 pointing towards the base 5, which is dimensioned such that the upper edge 7 of the longitudinal wire 2 is arranged below the apexes 8 of the bracket.
  • the brackets consist of a smooth galvanized wire to prevent the risk of rust in the over-concrete.
  • the spacers can have a length of 2.5 meters and a height between 20 and 60 mm and a division or a distance between the brackets of 150 mm.
  • the method of making spacers is explained using the schematic of FIG. 3.
  • the isolated and cut to length longitudinal wires 2 are held in a stack holder 11 and placed by a separating device 12 in time on a guide rail, not shown, and pushed into the predetermined starting position by means of a pneumatic cylinder 13.
  • the longitudinal wire is located in the welding machine 14, in which the first cross wire 15 is welded on.
  • This cross wire is placed in the correct position under the welding head of the welding machine by a suitable feed device 16.
  • the longitudinal wire with the welded-on transverse wire is moved forward by one unit, for example the division unit of 150 mm, by means of a transport device 17, whereupon the second transverse wire is welded on until the entire longitudinal wire has been provided with transverse wires.
  • the ends 3 of the cross wires are fitted with the plastic feet 4, the mounting system 18 having a storage silo and two sorting pots 19 for the feet, the outputs of which open at the ends of the cross wires, where the feet are brought into the correct position in order to a pneumatic cylinder.
  • the transverse wires are then deformed in a bending tool 20, which contains a pressure cylinder, in such a way that they have the appearance according to FIG. 1. In principle, this completes the actual manufacturing process, but a linear transport unit 21 is still required for complete automation makes sense with which the finished spacers are transported further. They can be transported directly for removal or on an elevator 22 in which the spacers are stacked and tied.
