Description

The invention relates to a device, in particular a wagon, for aligning a track support slab with respect to a subsoil with a chassis and a running gear for moving the chassis along the track support slab.

Furthermore, the invention relates to a method for aligning a track support slab with respect to a subsoil and a method for producing a solid track.

So-called slab tracks are used in railway construction and typically have a solid rail superstructure, which usually consists of concrete or asphalt, instead of ballast or other loose materials. Slab track is used, for example, on high-speed routes or in tunnels and is characterized by increased stability and durability compared to ballasted tracks.

In Central Europe, slab tracks often consist of prefabricated concrete track supporting slabs, which are typically prefabricated in a factory and then joined together on site and connected to the rails. Then the track support slabs together with the rails are precisely aligned according to the specified route. For this purpose, the laid track support slabs are measured using a measuring device and then aligned with the subsoil. This requires a team of several specialized people who work simultaneously on measuring and aligning a track support plate. Sometimes the position of a track slab needs to be remeasured or corrected. The production of slab tracks is correspondingly time-consuming and expensive. In any case, when aligning track supporting plates, a high degree of precision is required so that trains can later travel the route at high speeds without any safety risk.

Solid tracks and methods and devices for the production and alignment of solid tracks are, for example, from the prior art EP 2 503 059 A2 , the EP 1 039 033 A1 or the EP 1 533 420 A2 known.

In view of these statements, the invention is based on the object of alleviating or even completely eliminating the disadvantages of the prior art. In particular, it is the object of the present invention to provide a device and a method with which a quick, simple and precise alignment of track supporting slabs is made possible. Little or no personnel should be required for the alignment of track supporting slabs.

This problem is solved by a device with the features of claim 1.

According to the invention, a control unit and an adjustment device with at least one, preferably electrically driven, adjustment unit for adjusting at least one spacer element on the track support plate are therefore provided in a device of the type mentioned at the outset, the control unit being set up to receive an actual position of the track support plate from a position determination device and by activating the adjusting device, align the track supporting slab on the basis of the actual position according to a target position. The control unit can receive the actual position of the track support slab from the position determination device via cable or radio. The actual position of the track support slab can also be understood as the actual position of the chassis or running gear located on or on the track support slab, since the dimensions of the chassis and running gear are known and the actual position of the track support slab can therefore be determined from the actual positions of the Chassis or chassis can be determined. With the aid of the device according to the invention, an actual position of a track support slab can therefore be determined and aligned essentially automatically by adjusting the at least one spacer element according to a desired position. The actual position of the track support slab or the chassis and the running gear is adjusted until it corresponds to the target position or the difference is below a predetermined threshold value. In a particularly preferred embodiment, the device according to the invention is set up to align a track support slab in a fully automated manner with respect to the ground according to the target position. The chassis preferably has at least two even more preferably at least four or more wheels. The running gear can be adapted to travel along rails on a track support slab, for example by providing appropriate spacing between the wheels of a wheel pair or wheel set. The chassis can also be driven by one or more motors, in particular electric motors. The carriage is connected to the carriage so that the position of the carriage along a track support slab can be changed by the carriage. The chassis is preferably formed by a frame with longitudinal and transverse beams. The position determination device or components thereof can be connected to the chassis, in particular to a cross member or longitudinal member of the chassis. However, the position determination unit or components thereof can also be separate or separable from the chassis. In other words, the position determination device can have components that are permanently connected to the chassis and components that are not connected to the chassis or can be detached from it. The position determination device is set up to determine an actual position of the track support slab directly or indirectly and to transmit it to the control unit. The actual position can be transmitted by cable or via radio to the control unit, which can be arranged on the chassis or be separate from it. The control unit can be set up to control and/or regulate the alignment of the track support slab by actuating the adjustment device, with the feedback measured variable being the actual position of the track support slab determined by the position determination device and the setpoint as a reference variable or command variable. Position of the track support plate can serve. For this purpose, one or more control units, for example PI controllers or PID controllers, can be implemented in the control unit. In one embodiment, the actual position of the track support slab is compared to the target position during the alignment of the track support slab until the actual position essentially corresponds to the target position or the difference between them is below a predetermined threshold value. The actual position and the target position of the track support plate can be determined or specified relative to the ground. The actual position and the target position of the track support plate can also be relative to one or more marking points, which can be located, for example, on a tunnel wall or on marking poles. As already mentioned, the actual position and the target position of the track support slab can also be understood as an actual position and a target position of the chassis or running gear located on or on the track support slab, since their dimensions are known and therefore on the Actual position and target position of the track support plate can be closed. The measured actual position and the target position of the track support slab can at least describe a vertical distance to the subsoil or be converted into such a vertical distance, the vertical distance to the subsoil also being referred to as the height of the track support slab. The actual position and the target position can also describe an inclination of the track support slab relative to the ground. The position determination device can, for example, have an angle measuring device, in particular a theodolite and/or a tachymeter and/or a scanner, with which its actual position and subsequently also the actual position of the chassis and/or of the track supporting slab can be determined. In particular, it can be provided that the position determination device can determine the actual position of the chassis and will subsequently determine the actual position of the track supporting slab via the known dimensions of the chassis. The position determination device is preferably set up to determine the actual positions of the track support slab with an accuracy of +/-1 mm. The measurement of the actual position of the track support slab can be fully electronic and automated and transmitted to the control unit. However, it can also be provided that the position determination device is partly operated manually. The adjusting device according to the invention has at least one adjusting unit which is set up to adjust at least one spacer element on a track support slab. Depending on the embodiment, the adjusting unit can also connect the spacer element to the track support plate before adjustment, for example by screwing it in. The actuating unit can be driven hydraulically, pneumatically or electronically. The adjusting device and thus also the at least one actuating unit can be connected to the chassis, in particular to longitudinal members and / or the cross members of the chassis, preferably be connected directly. Typically, several spacer elements are provided on a track support plate, which is why several spacer elements are mentioned below. However, it is not absolutely necessary for several spacer elements to be provided on a track support slab; it is also possible for only one spacer element to be provided for each track support slab. The spacer elements on the track support slab are intended to space the track support slabs from the ground. The alignment of the track support plates can be changed by adjusting or adjusting the spacer elements, for example by twisting or locking. Depending on the type, the spacer elements can penetrate the track support slabs, for example from a top to a bottom via through holes, or be arranged laterally on the track support slab by means of holding elements. For example, the spacer elements can be spindles that penetrate the track support plate through corresponding through-holes. The spindles are formed by rods and have an external thread. The through holes can have corresponding mating threads. It is preferred if at least one magazine for spacer elements is connected to the chassis, from which the spacer elements can be removed, preferably automatically, and passed on to the at least one actuating unit. The at least one actuating unit can then connect the spacer elements to the track support slabs and set them according to the specifications of the control unit. The track support slabs can be made of concrete, for example. The track support slabs can each have a length of at least 5 m, for example. The standard length of typical track support slabs is usually 5.16 m. However, so-called shims with individual lengths can also be used.

In a preferred embodiment, it is provided that the at least one adjusting unit is a screwing unit for screwing in and/or unscrewing spindles on the track support slab or a locking unit for locking locking elements on the track support slab. Accordingly, spindles or latching elements can be provided as spacer elements. The spindles or latching elements can, for example, penetrate the track support plate and be connected to it in a positive and/or frictional manner. In the case of spindles or threaded rods as spacer elements As mentioned, track support slabs have, for example, through-holes with internal threads or sleeves with internal threads, into which the spindles can be screwed. With the help of spindles, a track support slab can be spaced from the subsoil and the distance of the track support slab from the subsoil and, if necessary, the inclination can be adjusted by turning the spindles. For example, rods with locking surfaces can be used as locking elements, which function similar to the principle of a cable tie. In the case of locking elements as spacer elements, the track support plates can have locking areas at suitable points with which the locking elements can preferably be releasably locked. The distance and the inclination of the track support slabs relative to the ground can also be adjusted with the locking elements. The screwing unit or the latching unit can be actuated electrically, hydraulically or pneumatically, for example. In the case of screw units, it is advantageous if the axis of rotation is arranged essentially perpendicular to a main plane of extent of the chassis. In one embodiment, the position of the axis of rotation can be adjusted, in particular electrically, hydraulically or pneumatically.

Since track support slabs are usually several meters long and spacer elements can be provided at several points, it is advantageous if the adjusting device has at least two, in particular at least four, adjusting units, which are preferably arranged on two opposite sides of the chassis. Provision can also be made for at least one actuating unit to be provided essentially in the middle of the chassis. The setting units are preferably arranged on opposite side members of the chassis, it also being possible for several setting units to be provided on one side member.

In order to fix the chassis during the alignment of a track support slab, it can be provided that the adjusting device has at least one gripping element, preferably at least two gripping elements, for gripping the track support slab or a rail on the track support slab. The at least one gripping element can be actuated electrically, hydraulically or pneumatically. At least this can be done during the alignment of the track support slab a gripping element hold the track support plate or the rail on the track support plate and thereby prevent unwanted displacement of the chassis. After the setting of the spacer element or elements, the at least one gripping element can be released again.

So that spacer elements can be precisely adjusted and slight displacements of spacer elements can be compensated for, it is advantageous if the at least one actuating unit can be positioned, preferably electrically, relative to the chassis. It is preferred if the at least one adjustment unit can be adjusted in a horizontal plane parallel to the main plane of extent of the chassis. Provision can also be made for the at least one actuating unit to also be displaceable along a vertical axis perpendicular to the main plane of extent of the chassis. The at least one adjustment unit can be adjusted electrically, hydraulically or pneumatically. Provision can also be made for an axis of rotation of the actuating unit to be adjustable.

It is preferably provided that the device also has a position determination device and the position determination device comprises a theodolite, a tachymeter, a scanner and/or a GNSS unit (GNSS - Global Navigation Satellite System), in particular a GPS unit (GPS - Global Positioning System). , having. By determining the actual position of the bogie, the actual position of the slab can be determined when the bogie is arranged on or at the slab, since the dimensions of the bogie are known. The position determination device, in particular the theodolite, the tachymeter and/or the GNSS unit, can—but does not have to—be connected to the chassis. The theodolite and/or the tachymeter can be removed from the chassis, preferably without tools, so that the theodolite or the tachymeter can be placed on a base. Alternatively, the position determination device can be connected to the chassis. The position determination device can use one or more marking points in the area to determine the position of the track support slab, for example on a tunnel wall or on a marking pole in the environment may be appropriate. The marking points may have been placed beforehand according to a plan. In order to determine the position of the chassis relative to the environment and subsequently the position of the track support slab, in particular a subsurface, at least one prism, in particular four prisms, can be arranged on the chassis, which can form part of the position determination device/ can and can be included in the measurement process. The at least one prism can be connected to the chassis. As already mentioned, four prisms are preferably arranged on the chassis. Two prisms each are preferably arranged on the chassis above a connecting line between a left front wheel and a left rear wheel or a right front wheel and a right rear wheel of the chassis, so that the prisms are arranged vertically above the rails when the chassis is on the track support plate is located. The actual position of the chassis can be determined with the aid of the at least one prism on the chassis and with the theodolite or the tachymeter. For this purpose, the theodolite or the tachymeter can preferably determine its own position and, with the aid of the at least one prism on the chassis and the at least one marking point, the actual position of the chassis. The actual position of the track support plate can subsequently be determined from the actual position of the chassis, since the dimensions of the chassis are known. The actual position of the track slab can be determined relative to the marking points or another reference point, for example a subsoil. In an alternative embodiment, it can be provided that the theodolite or the tachymeter is firmly connected to the chassis and the actual position of the track supporting slab is determined by determining the position of the theodolite, the scanner or the tachymeter and the dimensions of the chassis.

• Anordnen des Fahrgestells auf oder an einer Gleistragplatte;
• Bestimmen der Ist-Position der Gleistragplatte durch mit Hilfe einer Positionsbestimmungseinrichtung;
• Bestimmen einer Differenz zwischen der Ist-Position und der Soll-Position;
• Ausrichten der Gleistragplatte gegenüber dem Untergrund gemäß der Soll-Position auf Basis der Ist-Position durch Einstellen zumindest eines Distanzelements an der Gleistragplatte durch die Verstellvorrichtung.

According to the invention, a method for aligning at least one track support slab with respect to a subsurface is also provided, in which a device of the type described above is used. The procedure has the following steps:

• arranging the chassis on or at a track support plate;
• Determination of the actual position of the track support slab with help a position determining device;
• determining a difference between the actual position and the target position;
• Alignment of the track support slab relative to the ground according to the target position based on the actual position by adjusting at least one spacer element on the track support slab using the adjusting device.

At least one track support slab is aligned quickly and precisely according to a target position using the method described. It is also possible to align several track supporting slabs joined together. The steps do not have to be carried out in the specified order or some steps, such as "determining the actual position of the track support slab by the position determining device" or "determining a difference between the actual position and the target position" can also be carried out several times, for example , be carried out simultaneously and/or in between. On the basis of the determined difference between the actual position and the desired position of the track supporting slab, the at least one actuating unit can be controlled in such a way that the difference between the actual position and the desired position of the track supporting slab is made essentially zero. The at least one spacer element does not necessarily have to already be connected to the track support slab. Provision can also be made for the at least one spacer element to be connected to the track support slab before the adjustment. This can also be done by the adjustment device or the at least one control unit. A plurality of spacer elements are preferably provided on the track support slab. The chassis can preferably be moved automatically along the track support slab. To determine the actual position of the track support slab, the actual position of the chassis can first be determined with the position determination device. The actual position of the track supporting slab can be determined immediately via the dimensions of the chassis when the chassis is arranged on the track supporting slab. Due to this simple conversion, the actual position and the target position of the track support plate can also be understood as the actual position and the target position of the chassis or running gear. As described above, the position determination device can be a theodolite, a tachymeter, have a scanner and/or a GNSS unit. Furthermore, at least one prism can be provided, which can be arranged on the chassis. To determine the position, for example, the theodolite or a tripod connected to the theodolite, which can be removed from the chassis, can be placed on a surface and its own position, the Determine the actual position of the chassis and subsequently the actual position of the track support plate. The tripod can, for example, be set down on the ground through openings in the frame and the track support plate. The position can be determined several times, in particular during the alignment and after the alignment of the track supporting slab. In an alternative embodiment, the theodolite and/or the tachymeter is connected to the chassis and set up to measure its own position or the actual position of the chassis and subsequently the actual position of the track support slab, which is based on the known dimensions of the chassis can be determined. If the position determination device has a GNSS unit, this is permanently connected to the chassis.

In a further development of the method, it is provided that the track support slab is aligned in that several spacer elements are set at different positions on the track support slab using the adjusting device. If several setting units are provided, they can set the spacer elements simultaneously or one after the other. The spacer elements can be provided in edge areas and, in a preferred embodiment, also centrally on the track support slab.

In order to adapt the track support slab exactly to the planned course of the slab track, it is advantageous if the track support slab is aligned relative to the subsoil by adjusting the height and/or inclination of the spacer elements. The height describes the vertical distance to the ground. The inclination refers to an inclination around the longitudinal axis and/or around the horizontal transverse axis of the track supporting slab. The inclination can be adjusted, for example, by the spacer elements higher on one side of the slab and on the opposite side can be adjusted lower. If all spacer elements are changed in height at the same time or one after the other, only the distance between the track supporting slab and the ground is changed.

In one embodiment, it is provided that one or more track support plate(s) is aligned with the adjustment device at a number of alignment positions along the one or more track support plate(s) by adjusting spacer elements, with the chassis with the running gear preferably being driven electrically and in particular automatically between the alignment positions . If the adjustment device has a number of adjustment units, a number of spacer elements can be set at the same time or one after the other at the alignment positions. The alignment positions can be designed in the same way. An alignment position can be defined, for example, by a predetermined arrangement of spacer elements, through holes or sleeves on a track support plate. For example, in each case two through-holes arranged on opposite sides and at a certain distance from one another can preferably define an alignment position with spindles already inserted. The number of adjusting units of the adjusting device expediently corresponds to the number of spacer elements, through-holes or sleeves in an alignment position. The actual position of the track supporting slab can be determined with the position determination device in each case at the alignment positions.

It can be provided that the actual position of the track support slab is determined with the aid of at least one, preferably several, marking point(s) in the area, in particular on a building or tunnel wall. The marker point(s) may have been previously arranged according to a plan. As already described, a theodolite, scanner or tachymeter of the position determination device can use the at least one marking point to determine its own position and the actual position of the chassis using at least one prism on the chassis and subsequently the actual position of the track support slab. The theodolite or the tachymeter can determine the actual position of the track support plate automatically execute. In one embodiment, the theodolite can be connected to the chassis and can determine its own position using at least one marking point in the area. Based on the dimensions of the chassis, the actual position of the track support plate can be determined. In this embodiment, no prism is necessary on the chassis.

According to the invention, a method for producing a slab track with the following steps is also provided:

• arranging at least one track support slab, preferably on a concrete base, in particular with a steel plate placed thereon, and/or a steel grid;
• aligning the track support slab using a previously described method;
• Pouring an area under the track support slab with concrete;
• curing of the concrete.

With the method described, a slab track can be produced. Several track supporting slabs can be joined together.

In a preferred embodiment of the method it is provided that at least one rail—preferably two rails—is connected to the track supporting plate, in particular by screwing, before the chassis is arranged on the track supporting plate. A gripping element of the adjusting device can grip the rail to fix the device during adjustment of the spacer elements.

After the concrete has hardened, the at least one spacer element can be removed again. In the case of spindles, these can be unscrewed again. In the case of locking elements, these can also be released and removed from the locking mechanism.

1 shows a device 1 according to the invention for aligning track support slabs 2. The device 1 according to the invention has a chassis 3 which is connected to a chassis 4 on its underside. The chassis 3 and the chassis 4 can also be referred to as a carriage 1'. The chassis 3 is formed by a frame 3' with two lateral longitudinal members 3a and a plurality of cross members 3b. The parts of the frame 3' are arranged in a horizontal plane, as a result of which a flat construction of the device 1 is made possible. The chassis 4 is set up to move the chassis 3 along rails 5 on the track support plates 2 . The chassis 4 can be driven electrically and via one or more drives 50 (see 2 ) feature. In the embodiment shown, the running gear 4 has a plurality of wheel pairs 6 or wheel sets, with the distances between the respective wheels 6 ′ of the wheel pairs 6 being adapted to the distance between the rails 5 on the track support plates 2 .

A position determination device 7 which has a theodolite 8 is provided for determining the position of the track support plate 2 . In addition or as an alternative, the position determination device 7 can also have a GNSS unit (not shown) in order to facilitate or enable position determination in open terrain. The position determination device can be connected to the chassis 3, in particular if a GNSS unit is present. In the embodiment shown, the position determination device 7 can be removed from the chassis. Furthermore, in the embodiment shown, at least one prism 43 is provided on the chassis 3 for position determination, in the embodiment shown there are four prisms 43. The position determination device 7 is set up, with the aid of marking points 9 in the Environment, for example on a tunnel wall 41, an actual position P _is to be determined for a track supporting plate 2 at that point at which the chassis 3 is currently located. The prisms 43 are preferably arranged on the chassis 3 in such a way that they are located above the rails 5 when the chassis 3 runs on the track supporting plate 2 . The theodolite 8 is detachably connected to the chassis 3 or merely placed on it and can be removed from the chassis 3 or decoupled from it. During the alignment of the track support slab 2, the theodolite 8 can therefore be placed next to the track support slab 2, for example on a tripod 51 on the ground. However, the stand 51 or theodolite 8 can also be set down on the substructure 10 through openings in the frame 3' and through openings in the track support plate 2. In any case, the theodolite 8 can be decoupled from the chassis 3 in the embodiment shown, so that its position is not changed during the alignment of the track support plate 2 . While the chassis 3 is being moved from one alignment position 21 to the next, the theodolite can be arranged on the chassis 3 or placed on it. In the following, the determination of the actual position P actual of the track supporting plate 2 _is described as an example (see Figures 6A-6D ):
The chassis 3 is moved to an alignment position 21 with the help of the chassis 4 ( Figure 6A ). After moving the chassis 3 to the alignment position 21, the theodolite 8 is removed from the chassis 3 and placed on the base 10 ( Figure 6B ). By decoupling the theodolite 8 from the chassis 3, it is possible that the position of theodolite 8 is not changed by the alignment of the track support plate 2, which will be described in more detail below, which would be the case if the theodolite 8 with the chassis 3 during the alignment of the Track support plate 2 would remain connected. The theodolite 8 is set up to determine the actual position of the chassis 3 relative to the marking points 9 or relative to the ground 10 on the basis of the marking points 9 and the prisms 43 on the chassis 3 . To do this, the own position of the theodolite can first be determined ( Figure 6B , indicated by the dashed lines). The actual position of the chassis 3 is then determined with the aid of the prisms 43 ( Figure 6C , indicated by the dashed lines). By knowing the actual position of the chassis 3, the actual position P _act of the track support plate 2 can subsequently be determined, since the dimensions of the chassis 3 are known. Because of this simple conversion, the actual position and the target position of the track supporting plate 2 can also be understood as the actual position and the target position of the chassis 3 or the running gear 4 . During the alignment of the track support slab 2, the actual position P actual of the track support slab 2 _can also be continuously determined and used for regulation. After alignment, the theodolite 8 can be placed back on the chassis 3 and the chassis 3 can be moved to the next alignment position 21 ( Figure 6D ).

In an alternative embodiment, the theodolite 8 can be connected to the chassis 3 during the alignment of the track support plate 2 . During the alignment of the track support plate 2, the position of the chassis 3 and thus the position of the theodolite 8 is changed. The position of the theodolite 8 is therefore determined again after or during the alignment of the track support plate 2 . In this embodiment, prisms 43 are not absolutely necessary, since the position of theodolite 8 on the chassis 3 is known and consequently the actual position P _ist of the track support plate 2 can be determined if the position of theodolite 8 relative to the marking points 9 or to the Underground 10 is known.

In the following _, the actual position P actual describes at least a vertical distance z actual between a _track supporting slab 2 and a base 10 , which can also be referred to as the height of a track supporting slab 2 . Preferably _, the actual position P actual also describes an inclination ϕ actual of a _track supporting slab 2 about the longitudinal axis 11 and/or an inclination θ _actual about the horizontal transverse axis 12 of a track supporting slab 2 relative to the ground 10. Of course, the actual position P _ist can also other horizontal distances x _ist , y _ist and also an inclination ψ _ist along the vertical transverse axis 13 of the track supporting plate 2 describe. The actual position P act _can be forwarded to a control unit 17 via radio or cable for further processing.

In the manufacture of slab track, it is common prefabricated track support slabs 2 are first roughly placed on the construction site, joined together and connected to the rails 5 by screwing 42. As a rule, however, this rough placement does not correspond exactly to the planned desired position P _desired of the slab track or the track supporting slabs 2, so that the track supporting slabs 2 still have to be aligned in accordance with the desired position P _desired . In order to space the track support slabs 2 from the subsurface 10 and to change their orientation (see 3 ), in the embodiment shown, a plurality of adjustable spacer elements 14 in the form of spindles 15 are provided at different positions along the track supporting slabs 2 , which are arranged in through holes 16 in the track supporting slabs 2 . The spindles 15 can also be referred to as threaded rods with an external thread. The through holes 16 each extend from an upper side of a track support plate 2 to an underside of the track support plate 2 and have an internal thread (not shown). The spindles 15 screwed into the through-holes 16 support the track-supporting slabs 2 in relation to the base 10 and thereby space the track-supporting slabs 2 from the base 10.

The device 1 according to the invention has an adjustment device 18 with at least one setting unit 19 in order _to align the track support slabs 2 according to the target position P desired . In the embodiment shown, two adjusting units 19 are arranged on two opposite sides of the chassis 3 on the longitudinal beams 3a. Furthermore, a fifth control unit 19 is arranged essentially centrally on the chassis 3 on one of the cross members 3b. The adjusting units 19 are set up to set or adjust the spacer elements 14 on the track supporting plates 2 and thereby to change the alignment of the track supporting plates 2 with respect to the subsoil 10 . In the embodiment shown, the setting units 19 are formed by electrically operated screwing units 20 . The screw units 20 are set up to rotate the spacer elements 14 embodied as spindles 15 in the through holes 16 and thereby to change the position of the track support slabs 2 . The screwing units 20 are each arranged in such a way that it is possible to rotate a spindle 15 arranged essentially vertically. The axis of rotation 40 of the screw units 19 is therefore arranged essentially perpendicularly to the main extension plane of the chassis 3 . Two through holes 16 or spacer elements 14 arranged in two opposite edge regions of a track supporting plate 2 and a centrally arranged through hole 16 or a spacer element 14 define an alignment position 21. The control unit 17 described above receives the actual position P _ist of a track supporting plate 2 at time intervals at an alignment position 21 at which the device 1 is currently located, and controls the adjusting device 18 _to align the track support plate 2 by rotating the spindles 15 at the alignment position 21 according to the target position P desired. After aligning the track support slab at the alignment position 21, the device 1 can move to a next alignment position 21 on the same track support slab 2 or another attached track support slab 2 and align the track support slab 2 there again according to a target position _Psoll .

Like the actual position P actual _, the target position P target of a track support slab 2 can also _{be ,} in particular, a vertical distance z target from the subsurface 10 and preferably an inclination ϕ _target of the track support plate 2 about the longitudinal axis 11 and/or an inclination θ _target about the horizontal transverse axis 12 of the track support plate 2 relative to the ground 10 describe. A separate desired position P desired can _be specified for each alignment position 21 . The control unit 17 is set up to control or regulate the alignment of a track support slab 2 by actuating the adjustment device 18, with the feedback measurement variable y _mess in the case of regulation being the actual position P determined by the position determination _device 7 and as a reference variable or command variable R _ref the target position P _is used (see figure 5 ). For this purpose, a controller 22 , for example a PI controller or a PID controller, can be implemented in the control unit 17 . However, no provision needs to be made. After determining the difference between the actual position P actual and the target position P _{nom ,} the actuating units 19 can also be controlled directly in such a way that the difference is made zero. The actual position P actual _can also _be compared with the desired position P desired of the track supporting slab 2 during the alignment of the track supporting slab 2 until the actual position P actual _{corresponds to} the desired position P desired matches or whose difference is below a predetermined threshold. In the control unit 17, all target positions P target of all track support plates 2 and their alignment positions 21 can _be stored. These can also be retrieved by the control unit 17 from a server (not shown).

The track support slabs 2 can each have spacer elements 14 at a plurality of alignment positions 21, with which the alignment of the track support slabs 2 can be changed. Since the spacer elements 14 can be easily offset, it is favorable if the actuating units 19 can be positioned, preferably electrically, relative to the chassis 3 . The adjusting units can preferably be moved in a plane parallel to the main plane of extent of the chassis 3 .

In order to avoid unwanted displacements of the device 1 during the alignment of a track support slab 2, the adjustment device 18 can have at least one gripping element 23 with which the track support slab 2 or a rail 5 on the track support slab 2 can be gripped. After a track support plate 2 has been aligned at an alignment position 21, the gripping element 23 can be released again. In the embodiment shown, two gripping elements 23 are provided, one of which is arranged on two opposite sides of the chassis 3 .

As in 3 shown, to produce a slab track 24, track support slabs 2 are first joined together and placed on a concrete block or concrete base 25, in particular with a steel plate (not shown), or a similar base. A steel grid, not shown, can later be used to reinforce the concrete that is yet to be poured. In a preferred embodiment, counter elements 26 for the spacer elements 14 are placed on the substructure 10 below the track support plates 2 . In the embodiment shown, the counter-elements 26 are designed to at least partially accommodate spindles 15 and have an internal thread (not shown). The counter elements 26 improve the support of the spacer elements 14 against the ground 10. After the placement of the track support slabs 2 on the concrete blocks 25, these are like described aligned with the device 1. The spindles 15 can be supported on the concrete bases 25. After the alignment of the track support slabs 2, a new alignment, a follow-up check as to whether the actual position P actual of the _track support slab 2 actually corresponds to the desired position P desired _, or a control run with the device 1 can be carried out. During the control run, it _can also be checked whether the actual position _Pactually corresponds to the target position Psoll. A measurement protocol can also be created and transmitted automatically, preferably in real time, to a project storage platform. This allows the status of the work and the quality to be checked, preferably in real time. The area 27 below the aligned track support slabs 2 can then be filled with concrete (not shown). After the concrete has hardened, the slab track 24 is produced.
