The overhead station structure has uniqueness and representativeness in rail transit.
For an overhead station, the existing common overhead station for a common light rail is generally a light rail station in a steel wheel steel rail mode. Under normal conditions, the vertical distance between the vehicle floor and the roof beam roof of the light rail station is larger, and if the rail beam is directly supported at the roof beam roof, the height of a station plate, the height of the station and the climbing height of an escalator on a hall floor are increased, so that the construction difficulty is increased and the resource is wasted.
In the bridge-building combined system of the overhead station, the station structure mainly comprises a track beam for bearing the load of the train and a station house main body structure, and the track beam is hinged and supported on a station house structure cross beam by a rubber support. The bridge-building combined overhead station can better meet the building function requirement of the station due to simple and orderly arrangement of the station column net; however, the additional forces such as braking force or traction force, transverse swinging force, telescopic force, bending force, impact force and the like generated by the train and the track directly act on the main body structure of the station, so that great difficulty is brought to the design of the main body structure of the station. Thus, there is a need for a new modular construction "bridge-building" system to solve the above problems.
Therefore, the designer of the present invention has the above-mentioned drawbacks, and by means of intensive research and design, and comprehensive experience and achievement of related industries for a long period of time, a double-column frame station of an assembled bridge-building combination system is researched and designed to overcome the above-mentioned drawbacks.
