Superimposed track beam for magnetic levitation line

The utility model discloses a superimposed track beam for a magnetic levitation line. The utility model belongs to the technical field of magnetic levitation traffic, the track beam comprises an upper-layer steel structure track plate, a lower-layer bearing beam and a connecting mechanism between the upper-layer steel structure track plate and the lower-layer bearing beam. The section of the upper-layer steel structure track plate is of a T-shaped structure. The upper portion is covered with a steel structure track plate top sliding plate, the interior is of a hollow structure, the two side portions of the lower portion are in an inwards-concave arc shape, functional areas are arranged in the two sides in the width direction, transverse stiffening ribs and longitudinal stiffening ribs arearranged in the functional areas, and a connecting mechanism capable of adjusting relative displacement of the upper-layer steel structure track plate and the lower-layer bearing beam is arranged between the upper-layer steel
