Linear control method for mounting variable cross-section steel box arch rib
The invention provides a linear control method for mounting a variable-cross-section steel box arch rib, which comprises the following steps of: actually measuring and recording a space coordinate system of an environment in which a steel member is positioned, and forming on-site overall point cloud data; scanning each steel member of the processed combined bridge body by using three-dimensional scanning equipment to obtain point cloud data of the steel members needing to be assembled; checking the overlap ratio between the steel member entity three-dimensional model and the original design model in the three-dimensional processing software; pre-assembling the steel members through three-dimensional processing software, and checking the butt joint goodness of fit and line shape of joints between the entity three-dimensional models of the steel members; absolute coordinates of observation points of the steel member entity three-dimensional model are obtained; positioning a central axis and an observation point of the steel member; and hoisting the steel member. According to the method, the three-dimensional scanning technology is used for carrying out simulated splicing on the machined steel members, parameters of the arch rib sections are corrected, the coordinate positions of the arch rib sections are obtained, and then the installation speed of the variable-cross-section steel box arch ribs is increased.
本发明提供了一种变截面钢箱拱肋安装的线型控制方法，包括以下步骤：实测记录钢构件所处环境的空间坐标系，形成现场整体点云数据；用三维扫描设备扫描已加工的组合桥梁梁体各个钢构件，得到需要拼装的钢构件的点云数据；在三维处理软件内检查钢构件实体三维模型与原设计模型之间的重合度；通过三维处理软件进行钢构件预拼装，检查钢构件实体三维模型之间接头的对接吻合度和线形；获取钢构件实体三维模型观测点的绝对坐标；定位钢构件中轴线和观测点；吊装钢构件。本发明利用三维扫描技术对已加工完成的钢构件进行模拟拼装，修正拱肋节段参数，获取拱肋节段的坐标位置，进而加快变截面钢箱拱肋的安装速度。
