Long-connection seamless bridge and building integrated elevated station structure

Abstract

The invention discloses a long-connection seamless bridge and building integrated elevated station structure. The statically indeterminate number of times of the structure is reduced, temperature and internal force of shrinkage and creep times are released, and the construction and maintenance cost of a station project are greatly reduced. The long-connection seamless bridge and building integrated elevated station structure comprises a station superstructure, pier studs and bearing platforms, and the pier studs and the bearing platforms are arranged at intervals in the direction of a line. Each pier stud comprises a flexible connection pier stud and a rigid connection pier stud. The flexible connection pier studs are arranged at the two longitudinal ends of the station superstructure, the upper ends and the lower ends of the flexible connection pier studs are in flexible connection with the station superstructure and the corresponding bearing platforms through concrete hinges correspondingly, longitudinal corners can be generated between the station superstructure and the bearing platforms and the flexible connection pier studs, longitudinal bending moment transmitted from the upper part is released through the longitudinal corners, and only the vertical component force is transmitted to the flexible connection pier studs or the bearing platforms through the concrete hinges. The rigid connection pier studs are arranged between the flexible connection pier studs on the two sides, the upper ends and the lower ends of the rigid connection pier studs are fixedly connected with the station superstructure and the corresponding bearing platforms into a whole, and longitudinal force generated by the station superstructure is shared by the rigid connection pier studs.

Description

technical field [0001] The invention relates to urban rail transit bridge engineering and structural engineering, in particular to a concrete hinge suitable for long-link rigid elevated station structures, which can be used in the structural design of urban rail transit large bridges and elevated stations and other similar buildings. Background technique [0002] In recent years, my country's rail transit construction has achieved rapid development, and a large number of elevated lines with novel design, complex technology and difficult construction have been built one after another. Among them, the elevated station structure is unique and representative in rail transit. The "Jian-Bridge" integrated elevated station has gradually become the preferred design for elevated stations due to its advantages of convenient design and construction, economical applicability, and good passenger experience. However, due to its complex structure and many indeterminate times, the "Jian-Br...

AI Technical Summary

Problems solved by technology

This form has been widely used in urban rail transit elevated stations in recent years, but it has two defects. One is that it destroys the integrity of the station structure, and the other is that the expansion joints are prone to aging, and there are risks such as water leakage and subsidence. It is difficult, and it will affect the operation of the station in severe cases

[0005] 2. Increase the pier height

This method is to reduce the longitudinal stiffness by increasing the height of the station pier column, and increase the displacement of the top of the pier to release the structural stress. This method is used in some seamless stations, but the disadvantage is that this method will raise the line. Due to the length of the station, the high pier column will affect the normal use, so that the amount of various projects will increase simultaneously, and the investment in engineering equipment will increase, resulting in waste of the project

[0006] In summary, the existing methods have certain limitations, which bring great inconvenience to construction and operation.
