  • the control unit 17 described above receives the actual position P of a track support 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. After aligning the track support plate at the alignment position 21, the device 1 can move to a next alignment position 21 on the same track support plate 2 or another attached track support plate 2 and there again align the track support plate 2 according to a target position P.
  • the target position P should of a track support plate 2 can also have a vertical distance z should from the ground 10 and preferably an inclination ⁇ should of the track support plate 2 about the longitudinal axis 11 and / or an inclination ⁇ should around the Describe the horizontal transverse axis 12 of the track support plate 2 relative to the ground 10.
  • a separate target position P should 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 plate 2 by controlling the adjusting device 18, whereby in the case of regulation, the actual position P determined by the position determining device 7 is used as the feedback measured variable y mess and as a reference variable or command variable R ref the target position P is intended (see Fig. 5 ).
  • a controller 22 for example a PI controller or a PID controller, can be implemented in the control unit 17. It However, no regulation needs to be provided.
  • the actuating units 19 can also be controlled directly so that the difference is made zero.
  • the actual position P is can also be compared with the target position P of the track support plate 2 during the alignment of the track support plate 2 until the actual position P is matches the target position P should or their difference is less than one predetermined threshold value. All target positions P of all track support plates 2 and their alignment positions 21 can be stored in the control unit 17. These can also be retrieved from a server (not shown) by the control unit 17.
  • the track support plates 2 can each have spacer elements 14 at several alignment positions 21, with which the alignment of the track support plates 2 can be changed. Since the spacer elements 14 can be easily offset, it is advantageous if the actuating units 19 can preferably be positioned electrically relative to the chassis 3. The actuating units are preferably movable in a plane parallel to the main extension plane of the chassis 3.
  • the adjusting device 18 can have at least one gripping element 23 with which the track support plate 2 or a rail 5 on the track support plate 2 can be gripped. After aligning a track support plate 2 at an alignment position 21, the gripping element 23 can be released again.
  • two gripping elements 23 are provided, one of which is arranged on two opposite sides of the chassis 3.
  • track support plates 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 still to be poured.
  • counter elements 26 are used for the Spacer elements 14 placed below the track support plates 2 on the ground 10.
  • 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 relative to the ground 10.
  • the spindles 15 can be supported on the concrete bases 25.
  • a new alignment After aligning the track support plates 2, a new alignment, a follow-up check as to whether the actual position P is of the track support plate 2 actually corresponds to the target position P should , or a check run with the device 1 can be carried out. During the inspection drive, it can also be checked whether the actual position P actually corresponds to the target position P should .
  • a measurement report can also be created and transmitted automatically, preferably in real time, to a project storage platform. This means that the status of the work and the quality can be checked, preferably in real time.
  • the area 27 below the aligned track support plates 2 can then be filled with concrete (not shown). After the concrete has hardened, the slab track 24 is manufactured.
