There are many factors that affect the deformation and stress of steel structure in the construction process. Therefore, it is necessary to consider the deformation of steel structure affected by many factors before pre-assembly. How to control the machining and installation accuracy of these complex steel components is a difficult problem in the industry. BIM + 3D laser scanning technology is used to collect three-dimensional data of steel body construction, and accurate three-dimensional point cloud model is obtained. The deviation value of steel structure and design concept model can be easily judged by professional three-dimensional analysis software, which can not only effectively control the machining and installation accuracy of steel body structure, but also fully record the engineering site condition, and provide strong support for the reliability of data.References
