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

Abstract

The invention discloses a transition system for butt joint of a straddle-type monorail section turnout beam and a station. The system comprises a bearing platform foundation (1); the bearing platformfoundation (1) is provided with a station bridge pier (2) and a turnout beam bridge pier (10); the top of the station bridge pier (2) is provided with a station hall layer cover beam (3), a pluralityof station hall columns (4) are arranged above the station hall layer cover beam (3) at intervals for supporting a station platform layer cover beam (7) arranged on the station hall columns (4), and station rail beams (8) are longitudinally arranged above the station platform layer cover beam (7); the top of the turnout beam bridge pier (10) is provided with a turnout beam (6), the portion, corresponding to the station rail beams (8), of the turnout beam (6) is longitudinally provided with a mechanical turnout (9), the ends of the station rail beams (8) and the mechanical turnout (9) are rightopposite to each other, and the elevations of the top surfaces of the station rail beams (8) and the mechanical turnout (9) are the same, so that the butt joint of the straddle-type monorail sectionturnout beam and the station is achieved. The bearing requirement for the station pier due to the arrangement of brackets is avoided; the influence of the arrangement of the section transition rail beam on the use function of the turnout is also avoided.

Description

technical field [0001] The invention belongs to the technical field of rail transit bridge structures, and more specifically relates to a transition system for a straddle-type single-track section turnout beam connecting to a station. Background technique [0002] At present, only a small number of cities and regions at home and abroad adopt straddle-type monorail traffic as the rail transit operation line. The straddle-type monorail track girder is used as a bridge structure with integrated beam and rail, which must meet the requirements of bearing train load and train running alignment at the same time. Due to the unique operation mode of the straddle-type monorail mechanical turnout, the turnout girder often needs to be made very wide and heavy. When it needs to be directly connected with the station, the pier cover beam of the station often needs to be pulled through and slotted, and the view is very poor. Due to the heavy weight, the station cover girder often needs to ...

Problems solved by technology

[0004] Although in the prior art, corbels or simply supported beams are installed on the bridge piers of the station, the connection between the straddling monorail section turnout beam and the station can be achieved to a certain extent, but the section turnout beam generally has a large width, beam height and weight. When the turnout girder is built on the station pier, a larger corbel needs to be installed on the side of the station pier or the cover girder should be made very high. The volume is very large. At the same time, a support needs to be set on the corbel, and the weight of the turnout girder will also increase. Increase the burden on the station pier

If a simply supported beam with a hole is used as the transition span, the station or turnout needs to be moved as a whole, which may affect the applicable function of the turnout and cannot be moved freely due to terrain restrictions; Or to set corbels, the thickness of the grooved part of the station hall floor and the overall force capacity need to be strengthened, which also increases the burden on the cover beam and the station pier; moreover, between the two relatively large structures of the station and the track beam Set up small-span simply supported beams, and the landscape effect is also very general
