Shape-finding rigid connection method for erecting steel truss stiffening beam of suspension bridge
The invention discloses a shape-finding rigid connection method for erecting a steel truss stiffening beam of a suspension bridge. During implementation, a reasonable hoisting mode and a reasonable erecting sequence are selected by comprehensively considering factors such as transportation condition limitation of a construction site according to design data, a specific stiffening beam temporary connection and rigid connection scheme and a bridge deck welding scheme are formulated, and stiffening beams are installed according to the formulated schemes during erecting and installing; in the stiffening beam erecting process, the linear change condition of installed beam sections in the construction process is used for searching for the corresponding unstressed state lines of all the beam sections, rigid connection of the beam sections is completed in the unstressed state, and the welding work of bridge decks of the beam sections is conducted after rigid connection of all the beam sectionsis completed, and when all stiffening beams are erected, rigid connection of the beam sections and welding of the bridge deck slabs are synchronously completed. Compared with a traditional construction process, the process that all temporary hinge joints need to be subjected to hinge-fixing conversion after bridge deck slab construction and counterweight construction are completed is greatly improved.
本发明公开了一种悬索桥钢桁架加劲梁架设的找形刚接法，实施时根据设计资料，综合考虑施工场地运输条件限制等因素选择合理的吊装方式和架设顺序，制定具体的加劲梁临时连接和刚接方案以及桥面板焊接方案，加劲梁架设安装时按照制定的方案进行安装；在加劲梁架设过程中，利用施工过程中已安装梁段的线形变化情况，寻找各个梁段相应的无应力状态线形，在无应力状态下完成梁段的刚接，每个梁段在刚接完成后进行该梁段桥面板的焊接工作；全部加劲梁架设完成时也同步完成了梁段的刚接和桥面板的焊接。这相较于传统的施工工艺中所有的临时铰接口均需在桥面板施工和配重施工完成后才能进行铰固转换的工序得到大幅改善。
