Intelligent steel structure installation method based on digital twin technology

Abstract

The invention discloses an intelligent steel structure installation method based on digital twin technology. Before the steel structure is constructed, Revit is used for structural modeling to obtaina structure model. The structure model is imported into Ansys for mechanical performance analysis, and after the calculation is successful, detailed construction animation is made to complex nodes. The construction process is carried out by strictly following the model established by Revit, a 3D scanner will record each construction step in time to form point cloud data inverse modeling for comparison with the design model, and structural entities are adjusted to ensure that the construction is consistent with the design. After the assembling is completed, each connection node is equipped witha light sensor, and the construction quality problems can be checked in time through the data image of the sensors. In this way, from design to construction, each stage of monitoring realizes the mutual mapping of virtual reality to achieve a digital twin, which improves the quality and efficiency of construction. The intelligent steel structure installation method solves the problems such as poor assembly construction quality of complex steel structures and redundant node technology, and 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...
