Bridge-building combined elevated station structure and construction method
The invention discloses a bridge-building combined elevated station structure. Common pier columns are arranged at joints of station ends and interval bridges, the common pier columns are arranged attwo side ends of a station, and sliding support structures are arranged at the tops of the common pier columns and used for connecting station prestressed capping beams and the interval bridges; sliding supports of the sliding support structures are used for releasing longitudinal constraints along the station and limiting transverse displacement constraints along the station; rail carrying tablesand building carrying tables are arranged on the prestressed capping beams, first reinforced concrete beams are arranged on the rail carrying tables and used for installing a rail, and second reinforced concrete beams are arranged on the building carrying tables and used for bearing a platform building. The invention further discloses a construction method adapting to the station structure. The invention discloses a bridge-building combined elevated station structure system which is not provided with a temperature expansion joint, and the problem of temperature stress caused by concrete shrinkage and creep in the construction stage due to overlength of the station is solved.
本发明公开了一种桥建结合的高架车站结构，车站端头与区间桥梁接口位置设置共墩柱，车站的两侧端头均设置共墩柱，共墩柱顶部设置滑动支座结构，用于连接车站预应力盖梁和区间桥梁；滑动支座结构的滑动支座用于释放沿车站纵向约束，限制沿车站横向位移约束；预应力盖梁上设置轨道载台和建筑载台，轨道载台上设置第一钢筋混凝土梁，第一钢筋混凝土梁用于安装轨道，建筑载台上设置第二钢筋混凝土梁，第二钢筋混凝土梁用于承载站台建筑。本发明还公开了一种与车站结构相适应的施工方法。本发明公开一种“桥‑建”结合的高架车站结构体系，该车站结构体系不设置温度伸缩缝，解决车站超长带来的施工阶段混凝土收缩、徐变引起的温度应力。
