融合BIM模型和3D激光点云技术的装配式建筑误差控制OA

When assembling prefabricated buildings,effectively controlling connection errors between components can help reduce dismantling,assembly,and adjustment work,thereby improving the stability and structural strength of the building structure.Based on an error design and control methodology for pre-fabricated structures that integrates BIM models with 3D laser point cloud technology,this study designed a BIM model for prefabricated buildings.The 3D laser point cloud technology was employed to extract build-ing facade structures,develop detailed architectural models,and create BIM models for prefabricated build-ings using the integrated approach.Simultaneously,a global coordinate system is established to implement correction and control based on linear displacement errors and angular displacement errors,thus completing the design of the error correction method.The results indicate that the application of the above method can control the measured error within the allowable error range of the building,which has outstanding value in improving the stability and structural strength of prefabricated buildings.
