FIELD: construction.
SUBSTANCE: rail is preferably I-shaped and is located in a channel filled with cement. The rail is partially coated during manufacturing and as a whole along its entire length with a filler. The filler is limited at least by one side ledge resting against the cement. In the ledge there is a side slot to move a guide or a track roll. The rail is directly supported by cement without necessity to use intermediate devices for additional fixation. During installation the rail may be bent to comply with the curvature of the arrangement scheme without a separate or an additional stage, where bending takes place.
EFFECT: higher speed of installation, higher reliability of fixation and safety.
