Embodiment Construction

[0038] 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.

[0039] Refer below Figure 1-Figure 9 A track beam according to an embodiment of the present invention is described.

[0040] Such as Figure 1-Figure 9 As shown, the track beam according to the embodiment of the first aspect of the present invention includes a plurality of track beam segments 100 .

[0041] Specifically, the multi-segment track beam sections 100 are suitable to be arranged sequentially along the length direction of the track beam. Each track beam section 100 includes two longitudinal main beams 1 and a plurality of cross-links 2. 100 is arranged at intervals in the width direction, each cross-link 2 is connected between two longitudinal girders 1 , and a plurality of cross-links 2 are arranged at intervals along the length direction of ...

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 sections, each track beam section comprises two longitudinal main beams and a plurality of transverse bracings, the two longitudinal main beams are arranged at intervals in the width direction of the track beam sections, each transverse bracing is connected between the two longitudinal main beams, and the multiple transverse bracings are arranged at intervals in the length direction of the longitudinal main beams. According to the track beam, the cost can be greatly reduced, the transverse rigidity of the track beam sections can be improved, and a track vehicle can be prevented from being disengaged from the two longitudinal main beams. In addition, by adopting the track beam sections of the structure, the track beam sections are prefabricated in a factory at a time, construction is convenient, the construction quality, the construction precision and the production efficiency can be improved, and the cost 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 the related art, the track beam usually adopts a steel track beam structure or a concrete track beam structure. However, the steel track beam structure has defects such as high cost, poor durability, and high operation and maintenance costs, while the concrete track beam structure is heavy, which makes the transportation and hoisting of precast concrete track beams difficult, and the construction is complicated. 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 track beam, reduce the weight of the track beam section, improve the durability of the product, and reduce the cost of the product. [0004] Another object of the p...
