摘要

摘要: 装配式钢结构因其高效、环保等优点得到广泛应用，但从构件制造、运输至现场拼装，各环节易产生误差与变形，导致装配精度不足并影响结构安全。传统的施工调控依赖人工测量和经验判断，难以兼顾精度与效率。为提升装配精度并优化施工过程，构建了基于高精度三维扫描的数字化施工调控技术体系。首先，利用三维扫描获取构件几何形态与偏差数据，与设计模型比对，识别装配误差与关键控制位置；随后，在施工调控系统中集成误差分析与姿态优化，通过误差补偿算法生成构件安装调整方案，实现精确对接；同时依托数字化监测平台，对施工过程进行实时跟踪与反馈，动态修正调控策略。工程应用结果表明，该技术可显著提高装配式钢结构施工精度，减小误差累积对整体性能的不利影响，并在保证安全前提下，提升施工效率、降低综合成本。

Abstract: Prefabricated steel structures are widely used in modern construction for their efficiency and environmental benefits. However， during the assembly process， factors such as manufacturing errors， deformations during transportation， and on-site assembly inaccuracies can reduce assembly precision， affecting the structure’s stability and safety. Traditional construction control methods rely on manual measurements and empirical judgments， which are insufficient for achieving high-precision and high-efficiency construction. To address these challenges， first， high-precision 3D scanning technology was employed to accurately measure prefabricated steel components， capturing their shape and deviation data for comparison and analysis against the design model. Next， by integrating Building Information Modeling （BIM）， a digital construction control system was established to assess assembly errors and improve installation accuracy through optimization and adjustment strategies. Additionally， an error compensation algorithm was introduced to adjust component positioning and correct deviations based on working conditions， ensuring alignment during assembly. Finally， a digital monitoring platform enabl real-time tracking of the construction process， optimization of control strategies， and enhancement of construction quality and efficiency. Experimental studies and engineering applications demonstrate that this technology improves the assembly accuracy of prefabricated steel structures， mitigates the impact of error accumulation on overall structural performance， enhances construction efficiency， and reduces costs.
