In the prior art, a suspended monorail track beam column structure system in China generally adopts two forms of 'pin-penetrating suspension' and 'simple support', the 'pin-penetrating suspension' completes connection of a track beam and a beam column through a bolt, and the 'simple support' adopts a form of taking a pier bracket as a track beam support. In the 'pin-penetrating suspension' connection mode, the track beam is generally wrapped in a frame structure, and the track beam and the beam column are indirectly connected through the frame structure and the beam column through bolts; the mode of simply supporting is generally that the track sections forming the track beam are welded, and the track beam is supported on the bracket. In the installation process of the track beam column structure system adopting the pin-penetrating suspension, the assembly body of the track beam and the frame structure is required to be accurately hoisted at a specific space position, and the pin-penetrating operation can be completed, so that the problem of high assembly difficulty exists in the pin-penetrating suspension mode; after the installation of the simply supported rail beam column structure system is completed, the horizontal and vertical displacement restraining capability of the pier bracket on the rail beam supported above is poor, and the problem of poor riding comfort exists when a train passes through.
In the scheme, the side surfaces of the track beam body are the left side and the right side of the track beam body, bolt holes arranged on the track beam body are used for realizing the bolt connection between the track beam body and the bridge piers, and the strip-shaped ribs arranged on the outer side of the side surface of the track beam body are used for being matched with the strip-shaped grooves on the corresponding side surfaces of the bridge piers, so that when the track beam is assembled with the bridge piers, any side of each bridge pier can be used as the introducing side of the track beam, the end surface of the track beam is used as the introducing end, and after the strip-shaped ribs on the track beam are matched with the strip-shaped grooves on the bridge piers, the movement direction of the strip-shaped ribs can be limited through the strip-shaped grooves, so that the high-precision matching of the track beam and the corresponding bridge piers can be realized quickly, namely, the scheme is adopted, and the track beam is convenient to install on the bridge piers; in the scheme, the bolt holes are used for the bolt connection between the track beam and the bridge pier, so the track beam provided by the scheme can realize the detachable connection form between the track beam and the bridge pier, and meanwhile, the connection between the track beam and the bridge pier is reliable; the bar-shaped rib is adopted as a matching part between the track beam and the bridge pier, and the bar-shaped groove side on the bridge pier can be used for supporting the side surface of the bar-shaped rib, so that the shearing force or the pulling force of a bolt adopted between the track beam and the bridge pier can be reduced, and the stress of the bolt can be optimized by adopting the scheme, and the reliability of connection between the track beam and the bridge pier can be improved; in this scheme, owing to pass through bolted connection between track roof beam and the pier, so the track roof beam that this scheme provided need not adopt to weld the connection form when being connected with the pier, and the connection of bar rib and track roof beam body can be in workshop batch production accomplish, if adopt welded connection, can conveniently carry out heat treatment after the completion welding in order to improve mechanical properties, corrosion resistance etc. of bar rib and track roof beam body connector, and the same reason, be used for welding many strip-shaped plates to form on the connection face of pier with track roof beam the bar recess can also be in workshop batch production accomplish, and corresponding welding seam and heat affected zone can also improve mechanical properties, the corrosion resistance etc. of pier through carrying out postweld heat treatment in the mill, so the track roof beam that adopts this scheme to provide does not have the influence to self, the mechanical properties of pier in the assembly process, conveniently obtain the stable track roof beam post structure system of mechanical properties and corrosion resistance. Meanwhile, in the long-time service process of the track beam, along with the continuous increase of the transportation quantity, the action of various adverse factors in the environment and the degradation of the performance of the material, the track beam inevitably has diseases to cause the reduction of bearing capacity and the reduction of durability.
