Steel structure two-way curved arch bridge supporting structure and construction method
The invention discloses a steel structure two-way curved arch bridge supporting structure and a construction method and belongs to the technical field of bridge supporting system construction. The steel structure two-way curved arch bridge supporting structure is characterized in that a plurality of bridge floor supporting frames (12) are arranged side by side at intervals, arched girder supporting frames (13) are installed on the tops of at least two bridge floor supporting frames (12) and are in a gantry shape, bridge floor supporting platforms (5) are installed on the tops of the bridge floor supporting frames (12), arched girder supports (14) used for supporting arched girders are arranged on the tops of the arched girder supporting frames (13), and each bridge floor support frame (12) is arranged on a prefabricated foundation (1). According to the steel structure two-way curved arch bridge supporting structure, the overall stability of a frame body is improved, safety during construction is guaranteed, and meanwhile adverse effects caused by the fact that a bridge floor bears vertical loads are avoided. The construction method is an integral supporting system capable of supporting the bridge floor and the arched girder at the same time, and the problem that an existing bridge floor and an existing arched girder need to be separately and independently erected is solved.
一种钢结构双曲拱桥支撑结构及施工方法，属于桥梁支撑体系施工技术领域。其特征在于：桥面支撑架（12）并排且间隔设置有若干个，至少两个桥面支撑架（12）的顶部安装有拱梁支撑架（13），拱梁支撑架（13）为龙门状，在各桥面支撑架（12）的顶部均安装有桥面支撑平台（5），在拱梁支撑架（13）的顶部设置有用于对拱梁支撑的拱梁支座（14），各桥面支撑架（12）均安装在预制基础（1）上。本钢结构双曲拱桥支撑结构增加了架体的整体稳定性，保证施工期间的安全，同时避免了桥面承受竖向荷载而带来的不利影响；本施工方法能对桥面、拱梁同时起到支撑作用的整体支撑体系，解决现有的桥面、拱梁需要分开独立支设的问题。
