Single-column assembly type elevated station
The invention discloses a single-column assembly type elevated station. Large-span heavy-load reinforcing steel bars of an existing combined single-column elevated station are more, prefabricated parts are difficult to connect in a node area, and the energy dissipation capacity and the shock resistance are not ideal. Ground layer pier columns, station hall layer cantilever type cross beams, station hall layer single columns and platform layer cantilever type cross beams are connected into a whole through post-tensioning prestressed tendons, and stress longitudinal tendons at the joints of the components are connected through grouting sleeves; the station hall layer cantilever type cross beam and the platform layer cantilever type cross beam are each of a three-section prefabricated structure, prestressed double-T plates are laid on cantilever parts on the two sides, and concrete is poured later. And a pressure-bearing steel plate is pre-buried in the platform layer cantilever type cross beam below the platform interlayer prefabricated column. Main components are prefabricated in a factory, and the construction period is short; the overall stress performance is good, the self-resetting capacity and the assembling efficiency are high, and the energy dissipation capacity of the joint is improved.
本发明公开了一种单柱装配式高架车站。现有组合独柱高架车站大跨重载钢筋配筋较多，预制构件在节点区域连接困难，耗能能力和抗震能力不理想。本发明地面层墩柱、站厅层悬臂式横梁、站厅层单柱、站台层悬臂式横梁相互之间通过后张拉预应力筋连接成整体，构件间连接处受力纵筋之间采用灌浆套筒连接；站厅层悬臂式横梁与站台层悬臂式横梁均为三段预制式结构，两边悬挑部分均铺设预应力双T板，后浇混凝土；站台夹层预制柱下方的站台层悬臂式横梁内预埋承压钢板。本发明主要构件在工厂预制完成，施工周期短；整体受力性能良好，自复位能力和装配效率高，提升了节点耗能能力。
