Transition system for butt joint of straddle-type monorail section track beam and station

Abstract

The invention discloses a transition system for butt joint of a straddle-type monorail section track beam and a station. The transition system comprises a station hall layer and a platform layer; thestation hall layer comprises a station hall layer cover beam (8) and station hall columns (7), and each station hall column (7) comprises a side column body and a middle column body; the platform layer comprises a platform layer cover beam (4), station track beams (3) and section track beams (2) right opposite to the ends of the station track beams (3), the portions, correspondingly connected withthe side column bodies, of the platform layer cover beam are higher than the portions, correspondingly connected to the middle column bodies, of the platform layer cover beam, a station bridge pier groove (10) is formed in the portion, corresponding to the section track beams (2), of the upper portion of the top of the platform layer cover beam (4) and used for supporting the section track beams(2) in the station bridge pier groove (10), and the butt joint of the straddle-type monorail section track beam and the station is achieved; the clearance of the whole platform layer is not influencedwhile the overall track surface height is not increased, and the external landscape of the station is not influenced.

Description

technical field [0001] The invention belongs to the technical field of rail transit bridge structures, and more particularly relates to a transition system for a straddle-type single-track interval track beam to a station. Background technique [0002] Straddle-type monorail traffic is a kind of urban rail transit. It often has the advantages of low noise, strong adaptability, small footprint, low construction cost, and short construction period. The construction period of straddle-type monorail traffic is often not as good as that of subway construction. Half of the cycle, the construction cost is only about one-third of the subway, but it is a medium-capacity rail transit system, which can greatly improve the city's traffic problems. [0003] At present, only a small number of cities and regions at home and abroad use straddle-type monorail traffic as the rail transit operation line. Because there are certain differences between straddle-type monorail traffic and existing ...

Problems solved by technology

[0004] In the docking of the straddling monorail section track beam and the station track beam, the transition can only be realized if the top elevation of the two is consistent, so it is very important to solve the above problems. In the prior art, the following three methods are generally adopted. First, through Pad stones are set under the station track beams to increase the height of the station track beams to make up for the height difference between the station track beams and the section track beams, as shown in Figure 2 ~ Figure 4 As shown, but this method will increase the overall elevation and affect the stability of the transitional structure; secondly, set corbels at the pier of the station, but setting corbels will increase the load of the bridge body on the one hand, and on the other hand, will affect the joints Third, choose the same beam type as the station track beam when it is close to the station, and make a transition at the bridge pier close to the station. However, if a small-span transition span is used, the span is not coordinated, and because the station generally has an intersection, There is not necessarily a condition for setting excessive crossing
