Large-space curved surface steel structure roof mounting and positioning method
The invention provides a large-space curved surface steel structure roof mounting and positioning method. The method comprises the steps that a measurement control network is laid, and control points are established; deepening a steel structure construction drawing, and establishing a BIM three-dimensional model; determining a steel structure installation construction sequence; positioning and temporarily welding by a conventional measuring instrument; the three-dimensional laser scanner carries out entity digital scanning modeling; the BIM model and the point cloud model coincide, and 3D deviation is analyzed to generate an installation error of each component; and targeted correction is conducted based on the deviation condition of the component, and the steel component is finally welded. The installation and positioning precision of the large-space curved surface steel structure roof is guaranteed, a series of problems that subsequent buildings are not attractive, the structure is not safe and the like are solved, and remarkable benefits are brought to engineering construction.
本发明提供一种大空间曲面钢结构屋盖安装定位方法，包括布设测量控制网，建立控制点；深化钢结构施工图纸，建立BIM三维模型；确定钢结构安装施工顺序；常规测量仪器定位临时焊接；三维激光扫描仪进行实体数字化扫描建模；BIM模型和点云模型重合，分析3D偏差生成每个构件的安装误差；基于构件偏差情况进行针对性修正，钢构件最终焊接等步骤。本发明保证了大空间曲面钢结构屋盖安装定位精度，避免了后续建筑不美观、结构不安全等一系列问题，给工程建设施工带来显著效益。
