Embodiment

[0027] Such as figure 1 and figure 2 As shown, the prefabricated track girder of the tram includes an upper panel 1 and a lower panel 2 parallel to each other; there are at least two support parts 3 between the upper panel 1 and the lower panel 2, and every two adjacent support parts 3 The intervals between them are all greater than the width of the corresponding support portion 3 .

[0028] Principle of the present invention is as follows:

[0029] The overall weight is reduced through the middle and both sides of the support part 3, which is convenient for transportation; the track beam first needs to be manually woven with a steel cage that is similar in shape to the prefabricated part and has a smaller size, and then the woven steel cage is hoisted into the mold by driving and matched with the corresponding The parts are fixed, and then the prepared concrete is poured into the mold, vibrated and smoothed to form it.

[0030] In some embodiments, both the upper surface ...

Abstract

The invention discloses a tramcar prefabricated track beam and a construction method. The tramcar prefabricated track beam comprises an upper panel and a lower panel which are parallel to each other.At least two supporting portions are arranged between the upper panel and the lower panel, and the gap between every two adjacent supporting portions is larger than the width of the corresponding supporting portions. During construction, steel bars are firstly manually knitted into reinforcement cages matched with the upper panel, the lower panel and each supporting portion; meanwhile, a mold is set up; then the multiple reinforcement cages are placed into the mold and are fixed into a whole; and finally, prepared concrete is guided into the mold, and vibration leveling and forming are achieved. By means of the application of the tramcar prefabricated track beam and the construction method, the tramcar track beam can be prefabricated, the requirements of different specifications can be met, and pavement and manufacturing of different road conditions can be met.

Description

technical field [0001] The invention relates to the technical field of tram manufacturing, in particular to a prefabricated track beam of a tram and a construction method. Background technique [0002] In the prior art, most of the tramway track girders are built manually on site, and then concrete is poured into shape. [0003] In practical application, the prior art mainly has the following defects: there is no formed prefabricated part of the tram rail beam, and a lot of manpower and material resources are wasted. [0004] Therefore, how to simplify the construction steps of railcar track beams, reduce construction difficulty, reduce manpower and material resources, and shorten the construction period have become technical problems urgently to be solved by those skilled in the art. Contents of the invention [0005] In view of the above-mentioned defects of the prior art, the present invention provides a tramway prefabricated track beam and a construction method, and t...
