The invention discloses a steel structure intelligent installation method based on digital twin technology. Revit is used to carry out structural modeling before steel structure construction to obtain a structural model; the structural model is imported into Ansys for mechanical performance analysis. construction animation. During the construction process, the model established by Revit is strictly followed, and each construction step is recorded in time by the 3D scanner, and the inverse modeling of point cloud data is formed to compare with the design model, and the structural entity is adjusted to ensure that the construction is consistent with the design sex. After the assembly is completed, each connection node is equipped with a light sensor, and the construction quality problems can be checked in time through the data image of the sensor. In this way, from design to construction, each stage of monitoring realizes the mutual mapping of virtual reality to achieve digital twins, improving the quality and efficiency of construction. The invention aims to solve the problems of poor assembly construction quality of complex steel structures, redundant node processes and the like. The invention can be adapted to the installation of steel structure beams and columns.
Description
technical field [0001] The invention relates to the technical field of construction engineering, in particular to an intelligent installation and construction process for optimizing steel structures using digital twin technology. Background technique [0002] The installation process of steel structure beams and columns has a great influence on the construction quality of steel structures. The traditional installation processes include methods such as welding, bolt connection, and rivet connection. These traditional methods are not associated with intelligent equipment, and these methods are all There are shortcomings and deficiencies: [0003] Welding will produce light pollution and noise pollution, which is not conducive to building a green construction site. It is sensitive to fatigue. When some large sections and components are thick and large, the weld must be welded many times, and more materials are consumed in operation, which is easy to cause large shrinkage stres...
