Definitions

  • the invention relates to a rod mesh or bar mesh for the reinforcement of concrete, and more particularly the invention relates to a method and an apparatus for the handling thereof, including rolling-up of rod mesh during the manufacturing thereof, said rod mesh consisting of in its longitudinal direction extending steel supporting bands or strips and in the width direction extending reinforcement rods preferably secured by welding to the steel supporting bands, whereby the rod mesh is conveyed in the longitudinal direction of the steel supporting bands onto a rod mesh rolling-up device.
  • rod meshes are rolled up as a kind of loosely rolled up carpet roll being relatively flexible across its longitudinal axis and thus difficult to handle during transport and during mounting in the place where the rod mesh should be used. Normally it will be necessary to use a crane for handling of said rod mesh rolls.
  • EP 0 677 343 B1 discloses a rod mesh rolled up without a core, cf. claim 4. This provides a diametrally squeezable rod mesh roll which cannot be transported as a rigid drum. The related difficulties cause the need for particular facilities during transport, e.g. a crane.
  • the rod mesh during and after its rolling-up is exposed to a relatively high tensible force in the steel supporting bands and thus in the longitudinal direction of the rod mesh, causing the rod mesh to be tightly rolled up around the driving rings to act like a rigid and unsqueezable rod mesh roll which is reluctant to bend across its longitudinal axis and thus being easy to handle.
  • the rod mesh can be rolled across a substrate as a rigid drum without any energy consumption for overcoming a continuous deformation of the steel supporting bands, and maintaining safe parallel fastening of the reinforcement rods on to the steel supporting bands having been tightened up by said tensible force.
  • the outer diameter of the driving rings should be so big that the enforced bending forces of the steel supporting bands are kept within the yield point of the steel.
  • the method according to the invention may be characterized in that the following supporting means of the driving rings are realized by means of a pair of axially parallel supporting wheels arranged at a mutual distance, such as vehicle rubber wheels.
  • the method according to the invention may also be characterized in that the outermost ones of the steel supporting bands for the manufacture of the rod mesh each is supported by a combined band conveying and welding station which is displaceably arranged in the width direction of the rod mesh.
  • the method according to the invention can also be characterized in that the rotation of the rod mesh rolling-up device can be locked at each rotational stop during the manufacture of the rod mesh.
  • the method according to the invention may also be characterized in that after its rolling-up to a per se tightly fixed rod mesh, e.g. by means of binding wire, it is lowered, resting on the supporting wheels by lowering said wheels until the rod mesh is delivered for the rolling or sliding down on at least two opposite the welding station downwardly inclining discharge slides and furtheron for being delivered to a conveyor band, in a lorry, in a container or in a storing place.
  • the invention also relates to an apparatus or a machine for carrying out the method according to the invention, viz. an apparatus for use by handling, including the rolling-up, of reinforcement rolling netrworks for concrete during the manufacture of the rod meshes, said rod mesh consisting of in its longitudinal direction extending steel supporting bands and in its width direction extending reinforcement rods being secured preferably by welding to the stel supporting bands, and whereby the rod mesh is conveyed in the longitudinal direction of the steel supporting bands to a rod mesh rolling-up device.
  • the apparatus according to the invention is characterized in that the rod mesh rolling-up device - after the conveyed ends of the steel supporting bands having been conveyed to the rod mesh rolling-up device, has been arranged to synchroneously exposing the steel supporting bands of the rod mesh to a tensible force in the peripheral direction of at least two driving rings, that the driving rings are practically coaxially arranged as internal drive unit for the rod mesh and having an outer diameter corresponding to the desired inner diameter of the rod mesh, and that each driving ring is supported by a movable supporting means being synchronous following the radially outer periphery of the rod mesh, such as a pair of axially parallel supporting wheels, e.g. vehicle wheels arranged at a mutual distance, which wheels support each driving ring during its rotation via the layers of rod mesh being rolled up.
  • a movable supporting means being synchronous following the radially outer periphery of the rod mesh, such as a pair of axially parallel supporting wheels, e.g. vehicle wheels arranged at a
  • the apparatus according to the invention may also advantageously consist of one or more modules arranged subsequently in the longitudinal direction of the apparatus or the machine, whereby each single module has at least one and preferably two attached welding stations, each of which having a corresponding supply supply band roll with steel supporting band and at least one rod mesh rolling-up device with inherent traction means being arranged and provided to transmit a tensible force for rolling-up the steel supporting bands and so that the tensible force can be maintained during a temporary interruption of the rolling-up.
  • the apparatus according to the invention may also advantageously consist of at least two modules with end modules whereby the right welding station on one end module and the left welding station on the second end module can be adjusted so that the distance between these welding stations of the respective end modules can be adjusted.
  • the apparatus according to the invention - whereby the welding station has a welding table with a rail of a material having a relatively high specific heat capacity, said rail being so arranged that the steel supporting band may slide on the rail on its way from the supplly supply band roll to the rod mesh rolling-up device - may also be characterized in that next to, parallel to and somewhat below the rail of each welding table an exchangeable operating lever which is rotatable 90° around its axis is arranged and equipped with a number of parallel stop pins arranged perpendicularly to the operating lever at a mutual distance corresponding to a desired distance between the reinforcement rods of a rod mesh arranged longitudinally to the rod mesh, and rotatably by means of the operating lever between a vertical and a horizontal position.
  • the apparatus according to the invention can also be characterized in that it has one or two tubular driving shafts with a square cross section and being displaceable in their longitudinal direction, said driving shafts being driven from gear boxes arranged at one end or both ends, respectively, of the apparatus and having gear wheels with hollow shafts with driving key holes of square cross section where the side of the square is a little larger than the cross section sides of the driving shaft, whereby the driving rings have hollow hubs, likewise with driving key holes of square cross section, whereby the side of the square is a little larger than the cross section sides of the driving shaft.
  • the driving shafts with fixedly arranged gear wheels can follow the movement of the driving rings upwardly during the rolling-up of the rod mesh to the increasing diameter of the rod mesh, seeing that the relatively considerable clearance between the drive shafts and the driving key holes allows the driving shaft to tilt around the respective edges of the driving rings.
  • a supply band roll 1 with steel supporting band 2 is seen to the left, said roll passing a welding station wherein the reinforcing rod 4 are welded on for the formation of a rod mesh 3 which is seen in its rolled up condition to the left.
  • the invention is explained in detail in connection with rod meshes where the reinforcement rods 4 are welded on, they may of course also be otherwise secured to the steel supporting bands 2, e.g. by means of binding wire, staples or by adhesion.
  • Fig. 3 is shown an apparatus 6 or a machine consisting of three modules, viz. a left end module 7, a right end module 9 and an intermediate module 8.
  • Each module 7, 8, 9 is here provided with two welding stations 13.
  • the welding stations 13 arranged closest to the ends of the apparatus 6 are adjustable in the longitudinal direction of the apparatus so that the distance from said welding stations 13 to the ends of the apparatus can be varied.
  • the length of the cantilevered ends of the reinforcing rods 4 outside the supporting bands by the sides of the rolling net 3 can be varied.
  • a gear box 11 with gear wheels 12 for driving the rolling-up of the rod mesh 3.
  • Fig. 4 shows in the left side of the welding station 13 a supply band roll 1 for a steel supporting band 2.

  • a number of rods therefrom can be arranged in a tray 15 immediately above the welding table 14.
  • the welding of reinforcement rod 4 to steel supporting bands 2 takes place by a number of reinforcement rods 4 being arranged on and being welded to the steel supporting band 2 which is arranged on the rail 20 on the welding table 14. Thereafter the steel supporting band 2 is pulled one step forward and the welding can continue or the rolling-up of the rod mesh can be stopped.
  • the net rolling device 22 is seen in the left side of Fig. 4 .
  • the device consists of a driving ring 18 being driven via a shaft from the gear wheel 12 and on which an outermost reinforcing rod 4 being welded to the rod mesh on the steel supporting band 2 has been hooked, and around which the steel supporting band 2 with welded reinforcement rods 4 has been rolled up.
  • the drive unit 18 can follow upwardly when the rolling-up proceeds to a fully rolled up rod mesh 3.
  • the driving ring 18 is supported via the rod mesh 3 by a supporting means 19 following the periphery of the rod mesh 3, said supporting means consisting of two vehicle rubber wheels 19 supporting the driving ring 18 during its rotation via the rod mesh 3 being rolled up.
  • a chain wheel 23 with friction hub which is driven via a shaft from the gear wheel 12 might bring the vehicle rubber wheel 19 closest to the supply band roll 1 to rotation clockwise and may thus contribute to the rod mesh 3 being tightly rolled up.
  • a discharge slide 21 has been provided, along which the finished rod mesh 3 can slide or roll downwardly when the following supporting means 19 is tilted or lowered.
  • Fig. 5 shows an exchange- or replaceable operating lever 32 which can be arranged beside, parallel with and somewhat below the rail 20 of each welding table 14, and which is rotatable about 90° around its axis. It is equipped with a number of parallel and perpendicularly to the operating lever 32 arranged stop pins 33 at a mutual distance corresponding to a desired distance between reinforcing rods 4 arranged longitudinally to the rod mesh 3 and being arranged with the operating lever 32 between its vertical and horisontal position.
  • Fig. 6 shows a driving ring 18 with a square hub key hole 34, the square of which is a little larger than the cross section of the tubular driving shaft.
  • a hook 35 On the periphery of the driving ring 18 there may be arranged a hook 35 on which a reinforcement rod 4 on the rod mesh 3 can be hooked whereafter the tight rolling-up of the rod mesh 3 can be started.
  • Fig. 7 shows an axial section of the driving motor 24 of the gear boxes 11, said motor driving a friction hub 31.
  • a chain drive 29 therefrom is driving a gear wheel 12 arranged on a hollow shaft 26 with a square drive key hole 27 through which a tubular driving shaft 28 for a driving ring 18 and having a square cross section can be inserted, cf. Fig. 9 .
