Problems solved by technology

[0002] In related technologies, steel beams and concrete beams are generally used for track beam sections. Among them, the cost of steel beam sections is high, and in cold winter areas, the surface of steel beams is easy to Defects caused by accumulated water or ice, causing the tires of rail vehicles to slip; concrete beams have the defect of high noise when rail vehicles are running

Embodiment Construction

[0068] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary, and embodiments of the present invention are described in detail below.

[0069] Refer below Figure 1-Figure 8 A construction method of a track beam according to an embodiment of the present invention is described.

[0070] Such as figure 1 - As shown, the track beam according to the embodiment of the second aspect of the present invention comprises a plurality of track beam segments 100 .

[0071] Specifically, a plurality of track beam sections 100 are sequentially arranged along the length direction of the track beam, and each section of track beam section 100 includes two longitudinal beams 11 and at least one cross-link 12, and the two longitudinal beams 11 are arranged in the width direction of the track beam section 100. Set at intervals on the upper side, the cross-links 12 are connected between two longitudinal beams...

Abstract

The invention discloses a track beam and a construction method of the track beam. The track beam comprises a plurality of track beam sections, the track beam sections are sequentially arranged in the length direction of the track beam, each track beam section comprises two longitudinal beams and at least one transverse connection, the two longitudinal beams are arranged in the width direction of the track beam sections at intervals, the transverse connection is connected between the two longitudinal beams, each longitudinal beam and each transverse connection are of a concrete structure, and a walking structure is arranged at the top of each longitudinal beam and is of a sound absorption concrete structure. According to the track beam disclosed by the invention, noise generated by tires when a railway vehicle runs can be effectively reduced, the abrasion speed of the tires is reduced, the service lives of the tires are prolonged, the construction efficiency can be effectively improved, and the labor intensity is reduced.

Description

technical field [0001] The invention relates to the technical field of track beam manufacturing, in particular to a track beam and a construction method for the track beam. Background technique [0002] In related technologies, steel beams and concrete beams are generally used for track beam sections. Among them, steel beam sections have the disadvantages of high cost and cold winter areas, and the surface of steel beams is prone to water or ice, which causes rail vehicle tires to slip; The beam has the defect of high noise when the rail vehicle is running. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invention is to provide a rail beam, which can effectively prevent rail vehicle tires from slipping, and can effectively reduce the noise generated by the tires when the rail vehicle is running, and has a low cost. [0004] Another object of the pr...
