Definitions

  • the invention concerns a method of continuously producing a mesh-type support or lattice girder by welding a lower chord arrangement which includes at least one lower chord, in particular two lower chords, and an upper chord which is arranged at a specific height in relation to the lower chord arrangement to at least one diagonal member which extends back and forth between the at least one lower chord and the upper chord, in particular in a zig-zag form, wherein welding of the at least one lower chord and the upper chord to the at least one diagonal member is effected by means of a lower chord welding device and an upper chord welding device.
  • the invention further concerns an apparatus for continuously producing a lattice girder comprising a lower chord arrangement which includes at least one lower chord, in particular two lower chords, an upper chord arranged at a specific height relative to the lower chord arrangement and at least one diagonal member which extends back and forth between the at least one lower chord and the upper chord, in particular in a zig-zag form, wherein the at least one lower chord and the upper chord are welded to the at least one diagonal member and the apparatus for that welding operation includes a lower chord welding device and an upper chord welding device.
  • Lattice girders are reinforcement elements prefabricated in the factory for use by prefabrication plants. They are used in prefabrication plants in particular for the production of element slabs (floor slabs, semi-manufactured slabs, filigree floor slabs) and double-shell walls.
  • Lattice girders usually comprise two lower chords comprising generally profiled or ribbed concrete reinforcing steels, two zig-zag-shaped diagonal members which are welded thereto and which comprise generally smooth concrete reinforcement steels and an upper chord which is welded to the diagonal members and which comprises generally smooth concrete reinforcement steels.
  • Lattice girders are generally available only in certain standard sizes.
  • the characteristic sizes of a lattice girder include in particular the height at which the upper chord is arranged relative to the lower chord arrangement, the length of the lattice girder and the wire diameter of the chords and struts.
  • Only few manufacturers of lattice girders are in a position to meet the specific demands of a customer who is subjecting the lattice girders to further processing. This means that the customer has to accept a series of disadvantages:
  • WO 2005/021181 A1 shows for example a method and an apparatus for producing lattice girders of any length.
  • the lattice girders are cut from the continuously produced line of material at predetermined cutting positions. It will be noted however that in this case changing the other dimensions of a lattice girder, in particular the height at which the upper chord is arranged relative to the lower chord arrangement, involves a comparatively high level of complication and expenditure in conversion.
  • production also has to be interrupted for that purpose.
  • the object of the present invention is to avoid the above-described disadvantages and to provide a method of the kind set forth in the introductory part of this specification, which is simplified and improved over the state of the art, as well as a corresponding apparatus.
  • the apparatus according to the invention for which protection is also claimed besides the method according to the invention, for that purpose has a device for height adjustment of the upper chord during the continuous production of the lattice girder.
  • the device for height adjustment of the upper chord can be for example a height-adjustable carrier on which is arranged a holding device for the upper chord.
  • holding device includes a gripper, clamp or another technical solution which is usually employed by a man skilled in the art for that purpose, for releasably fixing the upper chord.
  • the apparatus desirably includes a cutting device for cutting the upper chord. That cutting device can be arranged for example on the above-mentioned height-adjustable carrier.
  • a further substantial advantage arising out of the combination of the device according to the invention for height adjustment of the upper chord during the continuous production of the lattice girder and the presence of a cutting device for cutting the upper chord is that ‘ad hoc’ conversion to the production of a lattice girder involving an altered upper chord height is possible without any loss of material worth mentioning.
  • the change in height can be effected completely between two welding cycles (for welding the upper chord to the diagonal members).
  • the apparatus according to the invention for carrying out those two welding steps, advantageously includes a device for adjusting the angle position of the lower chord welding device and/or a device for adjusting the height and/or the angle position of the upper chord welding device.
  • the apparatus according to the invention can for example include an advance device.
  • advance device is arranged on a linear carriage and is preferably movable by way of an eccentric lever.
  • the advance device can include grippers, clamps or other technical solutions which are usually employed by a man skilled in the art for that purpose. If the device for height adjustment of the upper chord includes a height-adjustable carrier it is advantageous for the advance device also to be arranged on that height-adjustable carrier.
  • the corresponding device according to the invention ideally includes a centering device which is preferably equipped with a gripper, clamp or another technical solution usually employed by a man skilled in the art for that purpose, for releasably fixing the upper chord. From a structural point of view it is advantageous for that centering device for the upper chord also to be arranged on the height-adjustable carrier which has already been mentioned a number of times.
  • the method according to the invention can further be developed by one or more of the following steps and in that way can be categorised in a wider overall context:
  • the corresponding apparatus preferably includes:
  • FIG. 1 shows a greatly simplified diagrammatic overall view of a preferred embodiment of the method according to the invention and the apparatus according to the invention for the continuous production of a lattice girder
  • FIG. 2 shows a diagrammatic side view of the welding machine
  • FIGS. 3 a and 3 b show two diagrammatic side views of the welding machine to illustrate the stepwise advance of the upper chord and the two lower chords
  • FIGS. 4 a through 4 f show a succession of six diagrammatic side views of the welding machine to illustrate the procedure for increasing the height of the upper chord relative to the lower chord arrangement during the continuous production of the lattice girder
  • FIGS. 5 a through 5 f show a succession of six diagrammatic side views of the welding machine to illustrate the procedure for reducing the height of the upper chord relative to the lower chord arrangement during the continuous production of the lattice girder,
  • FIGS. 6 a and 6 b show two diagrammatic side views of the lower chord welding device to illustrate the change in the angle position of that welding device in the course of the change in the height of the upper chord relative to the lower chord arrangement
  • FIGS. 7 a and 7 b show two diagrammatic side views of the upper chord welding device to illustrate the change in the height and the angle position of that welding device in the course of the change in the height of the upper chord relative to the lower chord arrangement, and
  • FIG. 8 shows a diagrammatic side view of a further preferred embodiment of an apparatus according to the invention for the production of a lattice girder.
  • FIG. 1 diagrammatically shows in greatly simplified form an overall view of a preferred embodiment of the method according to the invention and the apparatus according to the invention for the continuous production of a lattice girder 1 .
  • the lattice girder 1 comprises a lower chord arrangement which includes two lower chords 2 , an upper chord 3 arranged at a specific height H relative to the lower chord arrangement, and two diagonal members 4 which extend back and forth in a zig-zag form between the two lower chords 2 and the upper chord 3 , wherein the two lower chords 2 and the upper chord 3 are welded to the two diagonal members 4 .
  • the corresponding weld locations in spot form are denoted by reference 26 .
  • the upper chord 3 , the two lower chords 2 and the two diagonal members 4 are firstly unwound from drums 7 and 7 ′ in an unwinding device 22 .
  • the chords 2 and 3 and the struts 4 are delivered to the lattice girder manufacturer in the form of wound-on steel wires on those drums 7 and 7 ′.
  • the steel wires can be of different diameters and/or can involve different surface properties (profiled, ribbed or smooth).
  • the lower chords 2 and the upper chord 3 are fed to a straightening machine 23 and the two diagonal members 4 are fed to a bending machine 24 .
  • the straightening machine the lower chords 2 and the upper chord 3 are deformed substantially to form straight bars while the two diagonal members 4 receive a predetermined zig-zag form in the bending machine 24 .
  • the lengths L of the individual limbs of that zig-zag form or the bending angle ⁇ between the limbs can be freely selected.
  • the lower chords 2 and the upper chord 3 and the two diagonal members 4 respectively are fed to the welding machine 25 in which actual production of the lattice girder 1 is effected by welding the two lower chords 2 and the upper chord 3 to the two diagonal members 4 by means of a lower chord welding device and an upper chord welding device (not visible in this drawing).
  • the lattice girders 1 are transported into a storage location 9 by means of a robot device and set down there.
  • FIG. 2 shows a diagrammatic side view of the welding machine 25 .
  • This Figure shows the components of the welding machine 25 , that are required for substantial understanding of the mode of operation of the preferred embodiment.
  • a central component part is a device 10 for height adjustment of the upper chord in the form of a height-adjustable carrier 11 on which is arranged a holding device 12 for the upper chord.
  • That holding device 12 includes a gripper 13 for releasably fixing the upper chord.
  • the gripper 13 has two operating conditions: an opened condition in which the upper chord is not held fast and a closed condition in which the upper chord is pressed against a counterpart surface and fixed in that way.
  • a cutting device 14 for cutting the upper chord and an advance device 15 for stepwise feed of the upper chord and the two lower chords to the upper chord welding device 6 and the lower chord welding device 5 respectively (which can be seen at top right in the drawing). That advance device can be moved towards the right and left by way of a linear carriage 16 and a corresponding guide rail 30 by means of an eccentric lever 17 fixed to the frame 27 of the welding machine 25 .
  • the advance device 15 includes a gripper 18 for releasably fixing the upper chord and two grippers 19 for releasably fixing the two lower chords, only one of the lower chord grippers 19 being visible in this drawing (because of the side view).
  • the gripper 18 of the upper chord which is fixed to the advance device 15 , is not only displaceable in the horizontal plane but is also adjustable in height. In comparison therewith, it is not provided that the height of the two lower chords is changed. This means that a device 31 for height compensation must be provided between the component on which the two lower chord grippers 19 are arranged and the component on which the upper chord tong gripper 18 is arranged. In the embodiment illustrated here that height compensation is effected by means of rails. In general it should also be noted that the grippers 18 and 19 function just like the gripper 13 arranged on the holding device 12 for the upper chord. The two possible operating conditions are illustrated in the same manner.
  • a centering device 20 by means of which the upper chord can be centered, before it is fed to the upper chord welding device 6 .
  • That centering device 20 also has a gripper 21 for releasably fixing the upper chord.
  • a holding device 28 for the two lower chords Stationarily connected to the frame 27 of the welding machine 25 is a holding device 28 for the two lower chords, on which two further grippers 29 are arranged (in relation thereto the same applies as for the other grippers 13 , 18 and 19 ).
  • the upper chord welding device 6 is adjustable in height, as indicated by the two arrows. The precise operating principle of that height adjustment is described in detail precisely like the change in the angle position of the upper chord welding device 6 and the lower chord welding device 5 by reference to FIGS. 6 a and 6 b and FIGS. 7 a and 7 b.
  • FIGS. 3 a and 3 b serve to illustrate the mode of operation of the stepwise advance, by means of which the upper chord 3 and the two lower chords 2 are fed to the upper chord welding device 6 and the lower chord welding device 5 respectively. In principle this involves the same side view of the welding machine 25 as in FIG. 2 . The lattice girder can also be seen. It should be noted that in FIG. 3 b only the components of the welding machine 25 , that are relevant for understanding thereof, are denoted by references. The references of the other components can be seen from FIG. 3 a .
  • the stepwise advance in the horizontal direction takes place as follows: firstly the grippers 13 and 29 of the holding devices 12 and 28 for the upper chord 3 and the two lower chords 2 are closed. As a result those chords 2 and 3 are fixed in their position. Then the grippers 18 and 19 arranged on the advance device 15 are opened and the advance device 15 is moved towards the left by way of the eccentric lever 17 . In a further step (shown in FIG. 3 b ) the grippers 13 and 29 are opened, the grippers 18 and 19 are closed and the advance device 15 is moved towards the right by way of the eccentric lever 17 . Because the chords 2 and 3 are clamped fast at the grippers 18 and 19 and the chords 2 and 3 are welded together with the two diagonal members 4 behind the weld line the entire lattice girder moves towards the right.
  • FIGS. 4 a through 4 b serves to illustrate the increase in the height of the upper chord 3 relative to the lower chord arrangement during the continuous production of the lattice girder.
  • this involves the same diagrammatic side view of the welding machine 25 , which is also to be seen in FIGS. 2 , 3 a and 3 b . Therefore in those six views only the components relevant for understanding are also provided with references.
  • the references for the other components can be found in FIG. 2 a or 3 a .
  • the change in the height of the upper chord 3 relative to the lower chord arrangement during the continuous production of the lattice girder from a small height to a larger height takes place in detail as follows: at a given moment in time during welding of the two lower chords 2 and the upper chord 3 to the two diagonal members 4 the upper chord 3 is cut by means of the cutting device 14 at a predetermined cutting position.
  • the part of the cut upper chord 3 that is at the right in FIG. 4 a , is held in position by the welds 26 which have already been made while the part of the cut upper chord 3 , that is at the left in the Figure, is held fast by means of the closed gripper 18 .
  • the lattice girder is transported stepwise towards the right, the advance being effected by means of the advance device 15 in the manner described with reference to FIGS. 3 a and 3 b (see FIG. 4 b ). That stepwise advance continues until the location at which the upper chord was cut has reached the centering device 20 for the upper chord (see FIG. 4 c ). That means that the gripper 21 of that centering device 40 can fix the end of the left-hand part of the cut upper chord 3 . In that way that part of the upper chord 3 is held fast stably between the two grippers 18 and 21 and can subsequently be moved upwardly by an upward movement of the height-adjustable carrier 11 (which is indicated by the two upwardly pointing arrows). The two lower chords 2 remain in the original position. Account can be taken of the altered spacing of the two grippers 18 and 19 on the advance device 15 by means of the height compensation device 31 .
  • FIG. 4 d The end position of the upward movement of the height-adjustable carrier 11 is shown in FIG. 4 d .
  • the lattice girder is further moved stepwise towards the right (the stepwise advance again being effected by means of the advance device 15 in the above-described manner), more specifically until the end of the right-hand part of the cut upper chord 3 is completely welded, that is to say until the height change position has reached the lower chord welding device 5 and the upper chord welding device 6 respectively (see FIG. 4 e ).
  • FIGS. 5 a through 5 f serve to illustrate the reversed procedure (in comparison with FIGS. 4 a through 4 f ), that is to say a reduction in the height of the upper chord 3 relative to the lower chord arrangement during the continuous production of the lattice girder. It takes place in a similar manner and therefore does not have to be described in greater detail here.
  • FIGS. 6 a and 6 b and FIGS. 7 a and 7 b diagrammatically show a side view of the lower chord welding device 5 and the upper chord welding device 6 respectively. This involves a side view turned through 90° in comparison with FIGS. 2 through 5 f.
  • the corresponding sectional planes are denoted by references S 1 and S 2 in FIG. 2 .
  • the comparison of two views shows how the angle position of the lower chord welding device 5 and the height and the angle position of the upper chord welding device 6 can be changed in the course of the change in the height relative to the lower chord arrangement. In both cases it is effected by means of a height-adjustable hoop 32 and 35 respectively, an especially shaped lever mechanism 33 and 36 respectively and a curved guide contour 34 and 37 respectively.
  • FIG. 8 shows a diagrammatic side view of a further preferred embodiment of the apparatus according to the invention for the production of a lattice girder.
  • the right-hand part of the apparatus substantially corresponds to the welding machine 25 , the structure and mode of operation of which were described in connection with the preceding Figures. A difference however is that the welding machine 25 does not include the cutting device 14 for the upper chord 3 . That is now arranged in the left-hand part of the apparatus. More precisely it is disposed between a wire change device 41 and an advance device 40 for the upper chord 3 and a device 39 for wire guidance of the upper chord 3 .
  • the advance device 40 substantially comprises two rollers which rotate in mutually opposite relationship and between which the upper chord 3 is clamped.
  • the device 39 for wire guidance of the upper chord 3 substantially comprises a tube mounted at a first and a second location, wherein the height of the second support location is variable together with the height of the height-adjustable carrier 11 (see for example FIG. 2 ).
  • the cutting device 14 is arranged at a middle height in relation to the lower chords 2 .
  • the upper chord 3 to be welded can be conveyed by means of the device 39 out of that height to any desired height in relation to the lower chords 2 .
  • the left-hand part of the apparatus further includes a wire change device 42 , a cutting device 48 and a bending machine 24 . They serve to process the diagonal members 4 .
  • the diagonal members 4 and the lower chords 2 are fed to the production process at the same height so that they appear to be in superposed relationship as FIG. 8 is a side view. That is not the case in reality.
