A plurality of protrusions 31 protruding in the width direction of the track beam body 10 are formed on the reinforcing plate 3 of the track beam body 10, the protrusions 31 are arranged at intervals in the length direction of the track beam body 10, so that a plurality of connecting portions 32 arranged at intervals are formed on the reinforcing plate 3, and the guide panel 4 is detachably connected to the connecting portions 32, so that the reinforcing plate 3 provides a mounting surface for mounting the guide panel 4, and the guide panel 4 is prevented from being directly welded on the upper flange plate 1, therefore, the steps of polishing and painting are not required to be completed after welding, and therefore the guide panel 4 can be connected to the connecting portions 32 after polishing and painting in the assembling process of the track beam body 10, the polishing and painting space is further increased, and the assembling efficiency is improved.

In other embodiments, the first beam 101 may be a rail beam 10 described below, and the second beam 102 may be a beam structure of another form, or the second beam 102 may be a rail beam 10 described below, and the first beam 101 may be a beam structure of another form.
As shown in fig. 1 and 4, the track girder 10 includes an upper flange plate 1, a lower flange plate 2, a reinforcing plate 3, and a guide panel 4, wherein the upper flange plate 1 and the lower flange plate 2 are disposed to be opposite to each other in a vertical direction, the reinforcing plate 3 is connected between the upper flange plate 1 and the lower flange plate 2, the reinforcing plate 3 is formed with a plurality of protrusions 31, the plurality of protrusions 31 are spaced apart from each other in a longitudinal direction of the track girder 10 so that the reinforcing plate 3 is formed with a plurality of connecting portions 32 spaced apart from each other, the guide panel 4 is detachably connected to the connecting portions 32, and the guide panel 4 extends in the longitudinal direction of the track girder 10 so that a plurality of cavities are formed between the guide panel 4 and the plurality of protrusions 31.
A plurality of protrusions 31 protruding in the width direction of the track beam body 10 are formed on the reinforcing plate 3 of the track beam body 10, the protrusions 31 are arranged at intervals in the length direction of the track beam body 10, so that a plurality of connecting portions 32 arranged at intervals are formed on the reinforcing plate 3, and the guide panel 4 is detachably connected to the connecting portions 32, so that the reinforcing plate 3 provides a mounting surface for mounting the guide panel 4, and the guide panel 4 is prevented from being directly welded on the upper flange plate 1, therefore, the steps of polishing and painting are not required to be completed after welding, and therefore the guide panel 4 can be connected to the connecting portions 32 after polishing and painting in the assembling process of the track beam body 10, the polishing and painting space is further increased, and the assembling efficiency is improved. In addition, because the guide panel 4 is detachably connected to the reinforcing plate 3, the guide panel 4 and the reinforcing plate 3 can be transported separately in the transportation process, and the transportation cost of the track beam body 10 is greatly reduced.
Wherein, the surface of one side of the upper flange plate 1 departing from the lower flange plate 2 is formed into a walking surface for contacting with walking wheels of the rail vehicle, and the lower flange plate 2 is used for connecting with the pier stud, thereby fixing the rail beam body 10 on the pier stud.

In the embodiment shown in fig. 3 and 5, the connecting portion 32 is formed with a through hole, the guide panel 4 is formed with a counter sink hole, and the head of the bolt passes through the first through hole and is screwed in the counter sink hole, so as to prevent the bolt from passing through the guide panel 4 and affecting the contact between the guide panel 4 and the guide wheel. In a specific installation process, the space between two adjacent protrusions 31 provides implementation space for installation of the bolt, and the bolt is simple and convenient to assemble.
It will be appreciated that the bolts used to connect the guide panel 4 to the connecting portion 32 are provided in plurality, and the plurality of bolts form a plurality of bolt rows arranged at intervals in the vertical direction, each bolt row including at least one bolt. When the connecting portion 32 and the guide panel 4 are both formed with through holes, the plurality of bolt rows define a traveling space of the guide wheel in the vertical direction, so as to meet the traveling requirement of the guide wheel. For example, when a plurality of bolts form two bolt rows, one of which is connected to the upper portion of the guide panel 4 and the other of which is connected to the lower portion of the guide panel 4, when the rail vehicle travels on the rail beam 100 composed of the rail beam body 10, the guide wheels are interposed between the two bolt rows, and the distance of the two bolt rows in the vertical direction is increased as much as possible, thereby providing a space for possible movement of the guide wheels in the vertical direction. At this time, the head of the bolt may abut on the guide panel 4, or may abut on the connecting portion 32. When the head of the bolt rests against the connecting portion 32, the tail of the bolt is exposed to the guide panel 4 as little as possible or not exposed to the guide panel 4, so that the requirement for the vertical spacing of the rows of bolts can be reduced. In short, the bolts used to connect the guide panel 4 and the connecting portion 32 are preferably used so as not to interfere with the contact between the guide panel 4 and the guide wheel.
