Abstract

The invention discloses a track beam, a manufacturing method thereof and a design method of the track beam. The track beam has a manufacturing form and a bridge forming form, in an XOZ coordinate system, in the manufacturing form, the edges of the two transverse sides of the top face of the track beam are curves with the middle portions concave downwards along the Z axis, the end faces of the two longitudinal sides of the track beam are inclined relative to the Z axis, the distance between the end faces of the two longitudinal sides of the track beam is gradually increased in the direction from the top face to the bottom face of the track beam, and in the bridge forming state, the edges of the two transverse sides of the top face of the track beam are parallel relative to the X axis. The end faces of the two longitudinal sides of the track beam are parallel to the Z axis. According to the track beam disclosed by the invention, the manufacturing form of the track beam is set, so that the line type of the track beam in a bridge forming form meets the design requirement.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a rail beam, a manufacturing method thereof, and a design method of the rail beam. Background technique [0002] As a modern urban transportation tool, the straddle-type monorail transit system has obvious differences in structure form compared with other rail transit systems. To bear the vertical load and horizontal load of the train, such as centrifugal force, wind force, etc., it also bears the effect of large torsional load; at the same time, as the track for the train, it is required to have good operability, maintainability and economy. The characteristic of the straddle monorail system is that the beam and the track are integrated. The beam is not only a load-bearing structure, but also a track for vehicles to run. Therefore, the manufacturing and installation precision is extremely high. However, it is difficult to guarantee the line shape of the track beam i...
