Abstract
The roadway support of a steel roadway for magnetic tracks includes a cover plate (3) as an upper securing member which at the lower side of its two extending longitudinal edges is welded a side guiderail (4). Parallel to the guiderail and at a spacing thereto is a web-shaped longitudinal support (5) welded thereto, which carries the axial stator components (6). Extending at right angles to the longitudinal support (5) are spaced cross-support (8) which respectively pass as a unitary web connector between the two side guiderails (4). In their crossing region, the longitudinal supports (5) and the cross-supports (8) incorporate oppositely directed cutouts (9) and (10). The longitudinal support is fastened to only one of the two perpendicular side edges of the cutout (10) in the cross-support (8) through a welding seam (17) (FIG. 3).
