    The invention relates to a method for the continuous production of a lattice girder by welding a Untergurtanordnung comprising at least one lower chord, in particular two lower chords, and one arranged at a certain height to Untergurtanordnung upper chord with at least one between the at least one lower chord and the upper chord, in particular zigzag , Diagonalgurt running back and forth, wherein the welding of the at least one lower belt and the upper belt with the at least one diagonal belt by means of a Untergurt welding device and a Obergurt welding device takes place.
    The invention further relates to a device for the continuous production of a lattice girder from a lower chord assembly which comprises at least one lower chord, in particular two lower chords, a upper chord arranged at a certain height to the lower chord and at least one between the at least one lower chord and the upper chord, in particular zigzag, the diagonal belt running back and forth, wherein the at least one lower belt and the upper belt are welded to the at least one diagonal belt and the device for this welding comprises a lower belt welding device and an upper belt welding device.
    Lattice girders are factory prefabricated reinforcement elements for the use of precast plants. They are used in precast plants, in particular for the production of floor slabs (slab ceilings, semi-finished slabs, filigree ceilings) and double-skinned walls. Lattice girders usually consist of two lower chords of mostly profiled or ribbed reinforcing bars, two welded thereto, zigzag-shaped diagonal straps of mostly smooth reinforcing steels and a top chord of mostly smooth reinforcing steel welded to the diagonal straps.
    Lattice girders are usually only available in certain standard sizes. Among the characteristic sizes of a lattice girder are, above all, the height at which the upper girder is arranged in relation to the lower girder arrangement, the length of the lattice girder ···· »1 ·· ► ···· 1» · «· ti ·« 1 · · · · · «« «1 2 and the wire diameter of the straps. Only a few manufacturers of lattice girders are able to respond to the specific needs of a client processing the lattice girders. This means that the customer has to face a number of disadvantages: • Often, he only needs a certain amount of a particular lattice girder type, but often he has to accept a minimum quantity. This is especially problematic when many different types of lattice girder are necessary in a building. The lattice girders, which are not required, have to be temporarily stored by the customer, who not only has to provide the space required for them, but also suitable equipment for handling the bulky lattice girders. The decrease of a minimum quantity of a certain lattice girder type is also problematic against the background of strongly fluctuating steel costs, 1
    If he has to rework a lattice girder, which has certain standard sizes, for his specific purposes, then a large amount of waste is produced. In addition, additional, rarely standard-compliant welding work is required. The modification work also often causes rust-prone vulnerabilities. • The above-described disadvantages lead to an overall increase in costs.
    There are initial attempts to make the production of lattice girders more flexible in order to respond better to the specific needs of a client processing the lattice girders. WO 2005/021181 A1, for example, shows a method and an apparatus for producing lattice girders of any length. For this purpose, the lattice girders are separated in predetermined cutting positions of continuously produced strand of material. However, the change in the remaining sizes of a lattice girder, in particular the height at which the upper girder is arranged to the lower girder arrangement, is however also associated with a comparatively high conversion effort in this case.
    The object of the present invention is to avoid the disadvantages described above and to provide a comparison with the prior art improved and simplified method of the type described above and a corresponding device.
    This object is achieved by the features of the two independent claims 1 and 10.
    One of the basic ideas of the invention is therefore that the height of the upper flange is changed to Untergurtanordnung during the continuous production of the lattice girder. In the device according to the invention, for which, in addition to the method according to the invention protection is also desired, a device for height adjustment of the upper flange during the continuous production of the lattice girder is provided for this purpose. In this device for height adjustment of the upper flange may be, for example, a height-adjustable support on which a holding device for the upper flange is arranged. Advantageously, this holding device comprises a pair of pliers, clamps or another technical solution usually used by a person skilled in the art for the detachable fastening of the upper flange.
    In order to avoid a bending of the upper flange during the change of its height to Untergurtanordnung, it may be provided that the upper flange is cut before such a change in height. For this purpose, the device according to the invention expediently comprises a cutting device for cutting the upper belt. This cutting device may e.g. be arranged on the aforementioned height-adjustable support.
    As already stated in the introduction, the at least one lower belt and the upper belt are welded to the at least one diagonal belt by means of a lower belt welding device and a upper belt welding device. Now, if the height of the upper flange is changed to Untergurtanordnung during the continuous production of the lattice girder, it is advantageous, the angular position of the lower flange welding device and / or the height of the upper flange welding device and / or the angular position of the Obergurt welding device in the change of Height of the upper flange to change Untergurtanordnung. In this way, it can be sure that the welding always takes place in an optimal way. For carrying out these two method steps, the device according to the invention advantageously comprises a device for adjusting the angular position of the lower belt welding device and / or a device for adjusting the height and / or the angular position of the upper belt welding device.
    It has turned out to be particularly favorable when the upper belt and / or the at least one lower belt is supplied stepwise to the upper belt welding device or the lower belt welding device. Ideally, this incremental feed is adapted to the welding cycle of the two welding devices. For the technical realization of the stepwise supply of the upper belt and / or the at least one lower belt to the upper belt welding device or lower belt welding device, the device according to the invention may comprise, for example, a feed device. In the simplest case, this feed device is arranged on a linear slide and preferably movable via an eccentric lever. For detachable fastening of the upper belt and / or the at least one lower belt, the feed device can comprise pliers, clamps or other technical solutions usually used for this purpose by a person skilled in the art. If the device for adjusting the height of the upper flange is a height-adjustable carrier, it is advantageous to arrange the feed device also on this height-adjustable support.
    In order to ensure that the upper belt is fed optimally to the upper belt welding device, it may be provided to center the upper belt before its welding to the at least one diagonal belt in the course of the method according to the invention. For this purpose, the corresponding device according to the invention ideally comprises a centering device, which is preferably equipped with a pair of pliers, clamps or another technical solution usually used by a person skilled in the art for the detachable fastening of the upper flange. In constructive terms it is
    It is also advantageous to arrange this centering device for the upper belt likewise on the height-adjustable carrier already mentioned several times.
    The inventive method can be further extended by one or more of the following steps and arranged in this way in a larger overall context: The at least one bottom chord and / or the top chord and / or the at least one diagonal chord is welded to a lattice girder first before welding Coils unwound and then deformed in a predetermined manner, this deformation in the at least one lower chord and / or the upper chord is that these straps are deformed into straight bars, whereas the at least one diagonal belt in the course of this process step receives a predetermined zigzag shape. The lattice girder is separated in predetermined cutting positions from the continuously produced strand of material. The lattice girder is then fed to at least one deposit.
    In order to carry out these three method steps, the corresponding device according to the invention preferably comprises: An unwinding device for reels on which the at least one lower belt and / or the upper belt and / or the at least one diagonal belt are wound up; A straightening machine for the at least one lower belt and / or the upper belt and / or a bending machine for the at least one diagonal belt; a deposit for the storage of the lattice girder and 6 &liter; > > • a robot device for transporting the lattice girder to this deposit. Further details and advantages of the present invention will be explained in more detail below with reference to the description of the figures with reference to the exemplary embodiments illustrated in the drawings.

    In FIG. 1, a simplified overview of a preferred exemplary embodiment of the method according to the invention or the device according to the invention for the continuous production of a lattice girder 1 is shown schematically. The lattice girder 1 consists in this case of a Untergurtanordnung comprising two lower straps 2, a arranged at a certain height H to Untergurtanordnung upper flange 3 and two zigzag between the two lower chords 2 and the upper flange 3 back and forth diagonal straps 4, the two Bottom straps 2 and the top flange 3 with the two diagonal straps 4 are welded. The corresponding point-shaped welding points are provided with the reference numeral 26.
    To produce such a lattice girder 1, the top chord 3, the two bottom chords 2 and the two diagonal straps 4 are first unwound in an unwinding device 22 of spools 7 and 7 '. On these coils 7 and 7 ', the straps 2, 3 and 4 are supplied to the lattice girder manufacturer in the form of wound steel wires. Depending on the type of lattice girder to be produced, the steel wires may have different diameters and / or different surface qualities (profiled, ribbed or smooth).
    Subsequent to the unwinding of the reels 7 and 7 ', the lower chords 2 and the upper chord 3 of a leveler 23 and the two diagonal chords 4 are fed to a bending machine 24. In the leveler, the bottom chords 2 and the top chord 3 are substantially deformed into straight bars, while the two diagonal chords 4 in the bending machine 24 are given a predetermined zigzag shape. The lengths L of the individual legs of this zigzag shape and the bending angle a between the legs are freely selectable.
    Following the straightening machine 23 and the bending machine 24, the lower belts 2 and the upper belt 3 and the two diagonal straps 4 of the welding machine 25 are supplied, in which the actual production of the lattice girder 1 by welding the two lower straps 2 and the upper flange 3 with the two diagonal straps 4 by means of a Untergurt-welding device and a Obergurt-welding device (not visible in this drawing) takes place.
    After their preparation, the lattice girders 1 are transported by means of a robotic device into a deposit 9 and deposited there.
    FIG. 2 shows a schematic side view of the welding machine 25. Shown are the components of this welding machine 25 required for the essential understanding of the operation of the preferred embodiment. The central component is a device 10 for adjusting the height of the upper flange in the form of a height-adjustable support 11, on which a holding device 12 is arranged for the upper belt. This holding device 12 includes a pair of pliers 13 for releasably securing the upper flange. This pliers 13 has two operating conditions: an open state in which the upper belt is not held, and a closed state in which the upper belt is pressed against a counter surface and fixed in this way. These two operating states are indicated in this and in the remaining drawings, characterized in that the pliers 13 is filled in the closed state with a black color and in the open state has no filling. The mechanism for height adjustment of the height-adjustable support 11 is not shown in this drawing for clarity. This may be, for example, a chain drive, which is mounted on the frame 27 of the welding machine 25.
    On the height-adjustable support 11 is further a cutting device 14 for cutting the upper flange and a feed device 15 for the incremental supply of the upper flange and the two lower chords to Obergurt welding device 6 and the lower flange welding device 5 (which can be seen in the drawing, right above) arranged. This feed device 15 can be moved to the right and left via a linear slide 16 and a corresponding guide rail 30 by means of an eccentric lever 17 which is fixed to the frame 27 of the welding machine 25. The advancing device 15 includes a pair of pliers 18 for releasably securing the upper flange and two pliers 19 for releasably securing the two lower straps, wherein in this drawing (due to the side view) only one of the Untergurtzangen 19 is visible. Since the height of the upper flange to Untergurtanordnung during the continuous production of the lattice girder should be changeable, the pliers 18 of the upper flange, 4 ·· «·» # * · • I »« · »44 * I I * * · < which is attached to the feed device 15, not only adjustable in the horizontal plane but also adjustable in height. In comparison, it is not intended to change the height of the two lower chords. This means that between the component on which the two lower flange tongs 19 are arranged, and the component on which the Obergurtzange 18 is arranged, a device 31 must be provided for leveling. This height compensation takes place in the embodiment shown here with the aid of rails. In general, it should be noted that the pliers 18 and 19 as well as the pliers 13 arranged on the upper belt holding device 12 function. The two possible operating states are displayed in the same way.
    Finally, a centering device 20 is arranged on the height-adjustable support 11, with the aid of the upper belt - before it is the Obergurt-welding device 6 is supplied - can be centered, this centering device 20 also has a pair of pliers 21 for releasably securing the upper flange. Fixed to the frame 27 of the welding machine 25 is a holding device 28 for the two lower chords, are arranged on the two other pliers 29 (for the same as for the other pliers 13, 18 and 19).
    It should be noted that the upper belt welding device 6 is height adjustable, which is indicated by the two arrows. The exact mode of action of this height adjustment, as well as the change in the angular position of the upper belt welding device 6 and the lower belt welding device 5, are explained in detail with reference to FIGS. 6a and 6b and 7a and 7b.
    FIGS. 3a and 3b serve to illustrate the mode of operation of the incremental feed, with the aid of which the upper belt 3 and the two lower belts 2 are fed to the upper belt welding device 6 and the lower belt welding device 5, respectively. In principle, this is the same side view of the welding machine 25 as in FIG. 2. In addition, the lattice girder can be seen. It should be noted that in FIG. 3b only the components of the welding machine 25 relevant for the understanding are provided with reference numerals. The reference numerals of the remaining components can be taken from FIG. 3a. 10
    The stepwise feed in the horizontal direction (in this embodiment with a pitch of 200 mm) takes place as follows: First, the pliers 13 and 29 of the holders 12 and 28 for the upper flange 3 and the two lower chords 2 are closed. As a result, these straps 2 and 3 are fixed in position. Subsequently, the pliers 18 and 19, which are arranged on the advancing device 15, are opened, and the advancing device 15 is moved to the left via the eccentric lever 17. In a further step (which is shown in Fig. 3b), the pliers 13 and 29, the pliers 18 and 19 are closed, and the feed direction 15 is moved via the eccentric lever 17 to the right. Characterized in that the straps 2 and 3 are clamped to the pliers 18 and 19 and the straps 2 and 3 are welded together with the two diagonal straps 4 behind the weld line, the entire lattice girder moves to the right.
    The sequence of images shown in FIGS. 4a to 4f serves to illustrate the increase in the height of the upper flange 3 to the lower flange assembly during the continuous production of the lattice girder. It is in principle the same schematic side view of the welding machine 25, which can also be seen in Figs. 2, 3a and 3b. Therefore, only the components relevant for the understanding are provided with reference numerals in these six representations. The reference numerals of the remaining components can be taken from FIGS. 2 or 3a. The change in the height of the upper flange 3 to the Untergurtanordnung during the continuous production of the lattice girder from a small height to a greater height takes place in detail as follows: At a certain time during the welding of the two lower chords 2 and the upper flange 3 with the two diagonal straps 4, the upper belt 3 is cut by means of the cutting device 14 at a predetermined cutting position. The right in the drawing 4a part of the cut upper chord 3 is held by the already made welds 26 in position, while the left in the figure part of the cut upper chord 3 by means of the closed pliers 18 is held.
    Following the cutting of the upper belt 3, the lattice girder is transported stepwise to the right, wherein the feed with the aid of the feed device 15 in the manner explained with reference to FIGS. 3a and 3b (see Fig. 4b). This stepwise feed takes place until the point at which the upper belt has been cut has reached the centering device 20 for the upper belt (see FIG. 4c). This means that the pliers 21 of this centering device 20 can fix the end of the left part of the cut upper belt 3. In this way, this part of the upper flange 3 is stably held between the two pliers 18 and 21 and can be subsequently moved by an upward movement of the height-adjustable support 11 upwards (which is indicated by the two arrows pointing upwards). The two lower straps 2 remain in the original position. The changed distance of the two pliers 18 and 19 on the advancing device 15 is taken into account by means of the device 31 for height compensation.
    The end position of the upward movement of the height-adjustable support 11 can be seen in FIG. 4d. Upon reaching this end position, the lattice girder is further incrementally moved to the right (stepwise advancement again by means of the advancing device 15 in the manner described above) until the end of the right portion of the chopped top chord 3 is completely sealed, i. until the height change position has reached the lower belt welding device 5 or the upper belt welding device 6 (see FIG. 4e).
    In a last step (which can be seen in FIG. 4f), the upper belt welding device 6 still has to be moved upwards in order that the welding of the left part of the cut upper belt 3 with the diagonal belts can be carried out at the new (higher) height ,
    Finally, reference should be made to the following points: • After reaching the new height of the upper flange 3 to the lower flange arrangement, the angular position of the upper flange welding device 6 and the lower flange welding device 5 is optionally adjusted. 12 • # < • The supply of the two diagonal straps 4 is in contrast to the supply of the lower chords 2 and the upper flange 3 is not gradual but continuous. The corresponding device for this continuous feed from the bending machine to the welding machine is not shown in the drawings. The length of the legs of the zigzag Diagonalgurte 4 is automatically adjusted during the height adjustment of the upper flange 3 to the new height. After the right part of the cut upper belt 3 is completely welded, the corresponding lattice girder with the smaller height at the height change position is separated from the continuously produced material strand 8. For this purpose, a separator is provided, which is not visible in the drawings.
    The sequence of six images of the welding machine 25 shown in Figs. 5a to 5f serve to illustrate the reverse process (as compared to Figs. 4a to 4f). the reduction of the height of the upper belt 3 to Untergurtanordnung during the continuous production of the lattice girder. It takes place in an analogous manner and therefore need not be explained in more detail.
    In FIGS. 6a and 6b or in FIGS. 7a and 7b, a side view of the lower flange welding device 5 and the upper flange welding device 6 can be seen schematically. It is a side view rotated by 90 degrees compared to FIGS. 2 to 5f. The corresponding sectional planes are provided in FIG. 2 with the reference symbols S1 and S2. By juxtaposing two figures in both cases, it can be seen how the angular position of the lower belt welding device 5 or the height and the angular position of the upper belt welding device 6 can be changed as part of the change in height to the lower belt arrangement. It takes place in both cases by means of a height-adjustable bracket 32 and 35, a specially shaped lever mechanism 33 and 36 and a curved guide contour 34 and 37, respectively.
