    The invention relates to a method for the production of substantially arcuate structural steel mats from a plurality of bars by welding the bars to a structure consisting of longitudinal bars and transverse bars, starting at a front end by welding a first transverse bar to the longitudinal bars, generating a feed for positioning the longitudinal bars for all other transverse bar welds until reaching a desired rear end, wherein to achieve the arch shape of the reinforcing steel mat from the inside of the sheet to the outside of the sheet increasing feed distance is generated. Furthermore, the invention relates to a device for producing substantially arcuate construction steel mats, which consist of longitudinal bars and transverse bars welded together, the device comprising feed devices for the longitudinal bars, feed devices for the transverse bars and a welding device for welding the longitudinal bars to the transverse bars.
    Reinforced steel mats (also referred to as reinforcing mats) serve to reinforce (reinforce) concrete components. They are manufactured industrially on semi-automatic or fully automatic machines and consist of intersecting, typically corrugated steel bars, which extend in the longitudinal and transverse direction and are joined together at the intersection points by welding.
    An arcuate structural steel mat is a structural steel mat which is in its plane, i. in the plane which is defined by the structural steel mat, at least in an area is arcuate. This is achieved in that the distance between the welding points of two adjacent transverse bars is smaller with the longitudinal bars located inside the sheet, as the distance between the welding points of two adjacent transverse bars with the longitudinal bars lying in the sheet outer.
    Such arcuate structural steel meshes are used to reinforce round, half-round or conical concrete components, e.g. for reinforcing supports for
    Wind turbines, elements for tunneling, pipes or lighthouses used.
    It is known that arcuate structural steel mats are made in Schweißanlangen that one pushes the longitudinal bars through the welding portal, with the help of the Quererstweißenschweißungen are pushed through, while at the same time generates a feed path from the sheet interior to the bow outer. The advancing of the longitudinal bars is usually by means of feeders or feed rollers.
    This procedure for positioning the longitudinal bars for each upcoming welding cycle has several significant disadvantages: First of all, relative positioning errors between adjacent longitudinal bars can occur. Furthermore, the tracking or the slippage of the feed rollers can lead to an accumulation of positioning errors. These two effects lead to the bow-shaped steel mesh mats only with a relatively large inaccuracy, which varies from mat to mat, can be produced. If you want to reduce this inaccuracy, so laborious readjustments are required during the welding process of a mat, which significantly increases the production time. And finally, a conversion of the welding system on the production of a new mat type is very time-consuming, since the feed distance for each longitudinal bar must be set individually.
    Object of the present invention is to avoid the disadvantages described above and provide a comparison with the prior art improved and simplified method or a comparison with the prior art improved and simplified means for producing arcuate structural steel mats.
    This object is achieved by the features of the two independent claims 1 and 12.
    A basic idea of the invention therefore consists in that the advancement of the longitudinal bars for the respective welding cycle takes place by pulling on at least one welded transverse bar and / or longitudinal bar, preferably in the area of the front end of the curved structural steel mat. As a result, the desired for each longitudinal bar feed path is automatically achieved, since all the longitudinal bars are connected to this at least one transverse bar and / or longitudinal bar. Relative positioning errors between adjacent longitudinal bars and / or summation errors of positioning errors are excluded so that the arcuate structural steel mesh can be made with higher accuracy. In addition, the settings for the production of a new mat type can be made faster.
    The easiest way is when the feed is done by train on the first welded cross bar.
    Advantageously, the feed is carried out by train via a pulling device which is driven in the longitudinal and transverse directions and / or which is rotated in the plane of the structural steel mat. In a concrete embodiment example, it may be provided that the traction device comprises a cross slide, which is arranged on a longitudinal slide, wherein both the cross slide and the longitudinal carriage are drivable via a drive device or that the traction device comprises a rotary bar, which via a rotary drive device is rotatable in the plane of the structural steel mat.
    It has proved to be expedient if the at least one transverse bar and / or longitudinal bar on which or at which the train takes place can be released, for example detachably. is attached by a gripping device to the pulling device. In this case, the gripping device can be designed quite differently, e.g. with grippers, with clamping elements or - if they are magnetic steel bars - with electromagnets.
    Furthermore, it is advantageous if the pulling device can be controlled via a control device. This can be a certain one-time programmed expiration of a
    Welding process to produce a specific type of mat again and again in reproducible manner. In addition, it is possible to more easily and quickly switch between the settings for producing various types of mats. Such a control device may be technically e.g. be realized with the help of a computer.
    In a particularly advantageous embodiment of the method for producing arched building block mats, a method step is integrated, in which the sections of the longitudinal bars between a first and a second, subsequent crossbar welding after the first crossbar welding and the subsequent feed to prepare the second crossbar welding into a sheet be deformed. This method step is explained in more detail below in the description of the figures.
    Furthermore, the method can be supplemented by first inserting the longitudinal and transverse bars before welding, e.g. unwound from a package by means of a unwinding device and then deformed in a Rieht- or cutting machine to straight bars or cut to a predetermined length. Advantageously, the longitudinal and transverse rods are unwound in each case in the longitudinal direction and the transverse rods are rotated after cutting in the transverse direction. For this purpose, for example, be provided, preferably movable over rails, transport device.
    The process can also be extended to serve the production of three-dimensional truncated cone-shaped reinforcements for concrete components. Namely, this is possible by first producing an arcuate structural steel mat in the manner described and then bending it up three-dimensionally. This process step can be implemented particularly easily by means of the above-described traction device by first moving the traction device in a certain direction to produce the structural steel mat and subsequently reversing the direction of movement of the traction device to form the reinforcement, thereby bending the structural steel mat three-dimensionally. The bend can be technically, for example, using a
    Realize Aufbiegevorrichtung, which is preferably formed extendable and / or wedge-shaped.
    To be particularly advantageous has been found to produce the arcuate structural steel mat first in the horizontal plane and then to pivot such that the axis of symmetry of the three-dimensional truncated cone-shaped reinforcement at the end of the above-described manufacturing process substantially in the vertical direction, i. comes to a halt.
    The present invention also relates to a device for producing substantially arcuate structural steel mats. One of the characteristic features of this device is that it comprises, in addition to feeders for the longitudinal bars, feeders for the cross bars and a welding device for welding the longitudinal bars with the transverse bars also a pulling device for generating a feed path from the bow interior of the curved reinforcing steel mat to the outside of the sheet.
    It is advantageous if, in addition to the structural features already mentioned above, the device also has guide devices for the longitudinal bars on one side or both sides of the welding device.
    The guide devices, which are arranged on the side of the welding device, which faces the feeders for the longitudinal bars (i.e., in front of the welding line), serve to ensure that all the longitudinal bars have a certain distance from each other. For example, these guide devices can be guide rollers or guide plates. Advantageously, they can be tuned to a given Längsstabraster and / or (for the same purpose) exchange.
    By means of the guide devices, which are arranged on the side of the welding device, which faces the traction device (ie behind the welding line), the above-mentioned method step, which consists in that, the "* · I ··· · * * t · «· · · · · * * *» »4 9 *» a # «* * Ψ · · ** · * 6
    Sections of the longitudinal bars between each of a first and a second, subsequent cross-bar welding after the first cross-bar welding and the subsequent feed to prepare the second cross-bar welding to form an arc perform. For this purpose, it is advantageous if these guide devices can be pivoted in and / or are adjustable in the transverse direction via an actuator.
    As has already been explained above, an advantageous procedure is that the longitudinal and transverse bars are welded first before welding, e.g. unwound by means of a unwinding of coils and then in a straightening or. Cutting machine to straight bars deformed and cut to a predetermined length. To the longitudinal and / or transverse bars of this straightening or. To transport the cutting machine to the welding device, the device advantageously has movable transport devices. These transport devices may e.g. be movably mounted on rails.
    Finally, it has been stated above that the process for the production of substantially arcuate structural steel meshes can also be extended to be suitable for the production of three-dimensional truncated cone shell-shaped reinforcements. In this case, a procedure in which the reinforcing steel mat is first produced in the horizontal plane and then pivoted so that the axis of symmetry of the reinforcement at the end of the manufacturing process is substantially in the vertical direction, was found to be particularly advantageous. The feasibility of this procedure can for example be given by the fact that the area of the device comprising the welding device and the pulling device, is pivotally mounted.
    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. Showing:
    1 is a plan view of a schematically illustrated section of a preferred embodiment of the device for producing curved structural steel mats,
    Fig. 2a - 2c
    3a, 5b show a sequence of three drawings, in which a detail of an arcuate structural steel mat in the area of the welding line is shown schematically in plan view, in the plan view a diagrammatically illustrated overall view of the preferred exemplary embodiment from FIG. 1 in plan view, three different embodiments of an arcuate structural steel mat and a sequence of two drawings illustrating the method for producing a three-dimensional truncated cone-shaped reinforcement by bending an arcuate reinforcing steel mat.
    1, a detail of a preferred embodiment of the device for producing curved structural steel mats 1 is shown schematically in plan view. The longitudinal bars 2 are fed via a feed table 8 of the welding device 9 and welded to the transverse bars 3 to form an arcuate construction steel mat 1. The welding device 9 comprises a welding bridge with a plurality of, preferably with 12 × 3, movable multi-bladed heads (not shown in the drawing). Right and left of the welding device 9 guide devices 10 and 11 are arranged for the longitudinal bars 2. The guide devices 10, which are located in front of the welding line, are guide rails, which serve to ensure that all the longitudinal bars are at a certain distance from each other. In the illustrated embodiment, the guide rollers are tuned to a predetermined Längsstabraster. The guide devices 11, which are located behind the welding line, serve to form the sections of the longitudinal bars 2 into a bow between a first and a second subsequent transverse bar welding after the first cross bar welding and the subsequent feed in preparation of the second cross bar welding. This process will be explained in more detail with reference to FIGS. 2a-2c.
    As stated above, a basic idea of the invention is that the advance of the longitudinal bars 2 takes place by train for the pending welding cycle. In this case, in order to obtain the arch shape of the reinforcing steel mat 1, a feed path increasing from the inside of the sheet to the outside of the sheet must be generated. In the illustrated embodiment, the feed by train via a traction device 6. This traction device 6 comprises - two gripping elements 7, with the help of the first welded cross bar 3 'or one or more longitudinal bars 2' in the region of the front end 4 of the steel mesh 1 the traction device 6 are releasably secured, - a pivot bar 24, by means of which the front end 4 of the mat can be rotated in its plane via a rotary drive device, - a cross slide 23 which is arranged on a longitudinal slide 22, wherein both the cross slide 23 as Also, the longitudinal slide 22 are driven by a drive device and the longitudinal slide 22 along two rails 25 in the longitudinal direction L can be moved.
    The longitudinal direction L and the transverse direction Q are marked in the drawing by means of two arrows. It should be noted that the contours of the components in the area of the welding device 9 are shown projected onto a plane for better illustration, but are only partially visible in reality in plan view.
    For the production of the arched reinforcing steel mat 1, the following is used in the illustrated embodiment: First, a plurality of longitudinal bars 2 are fed to the welding device 9. Subsequently, a first transverse bar 3 'is welded to the longitudinal bars 2. Thereafter, this first welded transverse bar 3 'is releasably secured to the pulling device 6 by means of the gripping devices 7, so that the longitudinal bars 2 can be collectively positioned stepwise by means of the pulling device 6 for all subsequent cross bar weldings. In this case, the longitudinal slide 22 moves to the right, the cross slide 23 down and the rotary bar 24 is rotated clockwise. In this way, a feed path increasing from the inside of the sheet to the outside of the sheet is generated. In each case following a feed step, the sections of the longitudinal bars 2 between a first and a second, subsequent cross-bar welding after the first transverse bar welding and the subsequent feed to prepare the second transverse bar welding are deformed into an arc.
    This process will be explained in more detail below with reference to FIGS. 2 a and 2 b, wherein only a small section of the arch mat in the area of the welding line is shown in these figures. The longitudinal bars 2 are fed via the guide rollers 10 of the welding device 9 (which can not be seen in these figures) until they have reached the position Pos. 1. At this point, the longitudinal bars 2 are welded to a first transverse bar 3 at the points 27. Subsequently, the longitudinal bars 2 (by train) a piece in the direction of the arrow to be seen in Fig. 2a further moved until the first transverse bar 3 is in the position Pos. The sections 28 of the longitudinal bars 2, which are located between the guide rollers 10 and the transverse bar position Pos. 2, initially formed as a straight chord. In a second step, which is indicated schematically in FIG. 2 b, the guide device 11 is pivoted to the reinforcing steel mat after the feed. There it hooks behind an outer longitudinal bar portion and is then moved by an actuator a piece in the direction of the arrow, i. moved substantially perpendicular to the longitudinal bar sections 28. As a result, this outer longitudinal bar portion and thus at the same time all other longitudinal bar sections pulled so far outward until the longitudinal bars 2 have reached the transverse bar position Pos. 1 desired for the subsequent transverse bar welding desired positions in the transverse direction. In this way, the first formed as a straight chords sections 28 of the longitudinal bars 2, which are located between the guide rollers 10 and the cross bar position pos. 2, each deformed into an arc. Following this process step, the welding of a next transverse bar 3 takes place (see Fig. 2c).
    3 is a plan view of an overall view of the illustrated in Fig. 1 preferred embodiment of the device for producing curved reinforcing steel mats 1 to see. It should be noted in advance that this is a schematic representation (as with the other figures), ie that * * * * * * * * * * * * * * * * «* 4 1 * · · · 4 ··· «* · * 10 technical details, which are not important for the basic understanding, have been omitted. Right above eight coils 20 are indicated, which are located in a unwinding device 12. On these coils 20, the rods are wound, from which the reinforcing steel mat 1 is welded together, that is ,, that these rods are first unwound and fed to a Rieht- or cutting machine 13. Here they are first deformed into straight bars, cut to a predetermined length and finally placed on a bar outlet beam 14. The part of the rods, which is provided as longitudinal bars, is subsequently moved in the direction of the arrow by means of a transport device 15 movable over rails 16, transferred to a transfer device 17 and subsequently fed to the welding device 9 to the right by means of this transfer device 17. The part of the cut rods provided as crossbars is likewise fed to the welding device 9 in a corresponding manner by means of a transport device 18 which moves along two rails 19. Of course, these cross bars, so that they show Q in the transverse direction, must be rotated by 90 ° during this transport process. Therefore, the rails 19 have a 90 ° curve. The transport device 18 for the transverse rods is guided below the feed table 8 for the longitudinal bars to the welding device 9. The end positions of the transport devices 15 and 18 and the transfer device 17 are shown in dashed lines. It should also be noted that the transfer device 17 is movably mounted between two guide rails 29.
    With the aid of the device shown in FIG. 3, it is also possible to produce three-dimensional truncated-cone-shaped reinforcements for concrete components. For this purpose, an arcuate structural steel mat 1 in the horizontal plane, i. produced in the drawing plane. During the manufacture of the reinforcing mat 1, the pulling device 6 moves to the right. Following the last transverse bar welding, the direction of movement of the pulling device 6 is then reversed, ie, the entire mat 1 is pushed back to the left while being three-dimensionally arranged by wedge-shaped bending elements arranged in the area of the feed table 8 (not shown in the drawing) is bent. At the same time, the entire area 26 of the device comprising the welding device 9 and the traction device 6 is rotated by 90 °....... * Pivoted so that the axis of symmetry of the reinforcement at the end of the manufacturing process is substantially in the vertical direction.
    FIGS. 4a, 4b and 4c show three different embodiments of curved structural steel mats 1, which can be produced by means of the method or with the aid of the device. Thus, e.g. Mats with different radii of curvature, mats that are curved in only one area or mats are made in different widths and lengths. In addition, mild steel mats 1 can be produced with different crossbar or longitudinal bar spacing. The distance between the transverse rods 3 can be varied via a feed of different strengths, whereas the distance between the longitudinal rods 2 can be varied by an adjustment or an exchange of the guide rollers 10.
    FIGS. 5a and 5b schematically indicate the manner in which a three-dimensional truncated cone-shaped reinforcement 21 can be produced by bending from an arcuate structural steel mat 1. In each case, only the outer contour of the structural steel mat 1 is shown in these two figures. For reasons of clarity, the grid of longitudinal and transverse bars has been omitted. Following the three-dimensional bending of the reinforcing steel mat 1 to the reinforcement 21, the edges of the two ends 4 and 5 are advantageously still seized.
