Abstract: 1. A method relating to a travel way for a tracked vehicle, especially a magnetic levitation travel way, for the production of an exact positioning by measurement between connection points for the fastening of appurtenances (3) on a beam (2), or between functional surfaces (24, 25, 26) for the vehicle on said beam (2), wherein the appurtenances (3) or the functional surfaces which serve for the guidance of the said vehicle at an erection locale of the beam (2), therein characterized, in that the beam (2) at a fabrication facility is made essentially corresponding to its later erected dimensioning, at the construction site or is made with a defined deviation from its later erected dimensioning at the construction site, the positioning of the connection points between the beam (2) and the appurtenance (3) or the functional surfaces (24, 25, 26) are measured, and if required, their required specified measurement is established, since material at the connection point or on the functional surfaces (24; 25 26) is to be removed or added. 2. A method in accord with Claim 1, therein characterized, in that - a first specified (set) measurement ((set-E, Yset -E) for the erected condition of the beam (2) at the construction site is predetermined; - in the case of a deviation from the erected condition at the construction site of the beam (2) at the fabrication facility a second specified measurement ((set -B, Yset -B) for the rework condition of the beam (2) is established; - the actual measurement ((act-B, Yact-B) of the connection point or the functional surfaces (24, 25, 26) is determined in the rework condition of the Beam 2; and - if necessary the required first or the second specified measurement ((set -E, Yset -E ; (set -B, Y set-B) for the rework condition of the beam (2) is determined, since material at the connection point or at the functional surfaces (24, 25, 26) is removed or added, so that in the erected condition of the beam (2) the first specified measurement ((set -E, Yset -E) is adhered to. 3. A method in accord with one of the foregoing Claims, therein characterized, in that the beam (2), for rework, is placed in a position corresponding to its later erected position. 4. A method in accord with one of the foregoing Claims, therein characterized, in that the measurement is the outside measurement on the beam (2) embracing two connection points of functional surfaces (24, 25, 26) and/or an angle and/or, as seen in the longitudinal direction of the travel way, the separating distance and/or an angle of one connection piece to a previous and/or a following connection piece. 5. A method in accord with one of the foregoing Claims, therein characterized, in that the specified set distances, where measured in reference to reference points, reference lines, or reference planes, the measurements are especially based on the centerline of the beam (2). 6. A method in accord with one of the foregoing Claims, therein characterized, in that the beam (2) is a precast concrete beam, which, before the rework has been stored until essentially the shrinkage of the said beam (2) has reached an equilibrium. 7. A method in accord with one of the foregoing Claims, therein characterized, in that the beam (2) before the rework of its connection points or its functional surfaces (24, 25, 26) is stored for some 60 days. 8. A method in accord with one of the foregoing Claims, therein characterized, in that the appurtenances (3) are placed in location, after the rework of the connection points, but before the erection of the beam (2) to the travel way. 9. A method in accord with one of the foregoing Claims, therein characterized, in that the appurtenances (3), before or after their installation on the beam (2) are measured by usual shop quality monitoring. 10. A method in accord with one of the foregoing Claims, therein characterized, in that the appurtenances (3) are measured magnetically and the specified measurement of the beam (2) is determined with dependence upon this magnetic measurement of the appurtenances (3). 11. A method in accord with one of the foregoing Claims, therein characterized, in that the measurement is carried out by means of a tracked vehicle (30). 12. A method in accord with one of the foregoing Claims, therein characterized, in that the connection point is provided on a console (1) connected to the beam (2). 13. A method in accord with one of the foregoing Claims, therein characterized, in that the connection point on the console (1) is mechanically reworked before and/or after the erection on the beam (2). 14. A method in accord with one of the foregoing Claims, therein characterized, in that material which is removed by machining, is especially removed by milling or boring. 15. A method in accord with one of the foregoing Claims, therein characterized, in that the material is added on by welding. 16. A method in accord with one of the foregoing Claims, therein characterized, in that additional material, especially a disk, or spacer plate is placed on the connection point as a distance increasing means. 17. A method in accord with one of the foregoing Claims, therein characterized, in that the measurement and rework is carried out after the ending of the deformation of the beam (2) and/or the storage of the beam (2). 18. A method in accord with one of the foregoing Claims, therein characterized, in that the console (1) and/or the appurtenance (3) is attached onto the beam (2), which is manufactured as a precast concrete beam. 19. A method in accord with one of the foregoing Claims, therein characterized, in that the material on the connection point or on the functional surfaces (24, 25, 26) is removed or added locally at the construction site.
