Positioning and mounting method for bracket of arch rib supporting tube of steel tube arch bridge
The invention discloses a positioning and mounting method for a steel tube arch bridge arch rib supporting tube bracket, and belongs to the technical field of steel structure bridge engineering structure building processes. According to the positioning and mounting method for the arch rib supporting pipe bracket of the steel pipe arch bridge, the bracket can be directly and accurately preassembled to the corresponding position of a left arch rib and/or a right arch rib of a steel truss. The positioning and mounting method comprises the steps that a BIM model is established according to the proportion of 1: 1, then an arch rib is prepared and assembled based on the BIM model, a supporting pipe bracket is prepared, and intersecting lines, part assembling sizes, part positioning center points and part mounting cross lines are marked on the arch rib and the supporting pipe bracket based on the BIM model; cutting the intersecting line of the connecting end of the supporting pipe bracket, and mounting a laser positioner in the supporting pipe bracket; and finally, mounting the supporting pipe bracket on the corresponding position of the arch rib by virtue of alignment and alignment of the laser positioner, the positioning center point of the part and the cross-shaped mounting line, so as to complete the mounting work of the supporting pipe bracket on the arch rib in a factory.
本发明公开了一种用于钢管拱桥拱肋支撑管牛腿的定位安装方法，属于钢结构桥梁工程结构物建造工艺技术领域。提供一种可以直接将牛腿准确的预装到钢桁架左幅拱肋和/或右幅拱肋上的相应位置的用于钢管拱桥拱肋支撑管牛腿的定位安装方法。所述的定位安装方法先按1:1的比例建立BIM模型，然后基于BIM模型制备拼装拱肋、制备支撑管牛腿，并基于BIM模型在拱肋和支撑管牛腿上标注相贯线、零件装配的尺寸、零件定位的中心点以及零件安装的十字线，接着切割支撑管牛腿连接端的相贯线并在支撑管牛腿内安装激光定位器，最后借助激光定位器和零件定位的中心点以及十字安装线找正对位将支撑管牛腿安装到拱肋的相应位置上完成拱肋上支撑管牛腿厂内的安装工作。
