摘要
预制构件生产作为装配式建筑全生命周期中的重要环节,其生产质量影响着装配式建筑的最终质量。在预制构件生产过程中,往往会因为模具变形、工人操作不规范等问题导致预制构件出现缺棱掉角、预留孔被封堵、构件尺寸和预埋件位置偏差等质量缺陷。本研究基于视觉识别技术和BIM技术,为预制构件生产过程中的质量控制及成品质量检测提供新的解决方案。试验效果和实测偏差数据分析表明三维激光投影定位技术能够快速定位、校核预制构件中钢筋、预埋件、预留孔等关键信息,三维扫描技术能够快速识别和量化预制构件的尺寸及预留预埋位置偏差,该集成技术可以为装配式预制构件的精益制造提供支持,提高预制构件生产、质量和效率,在装配式建筑智能制造过程中具有广阔的应用前景和巨大的应用潜力。
The prefabricated component production is an important link in the entire lifecycle of the prefabricated buildings,and the production quality affects the final quality of the prefabricated buildings.During the production process of prefabricated components,quality defects such as missing edges and corners,blocked reserved holes,and deviation in component size and embedded part position often occur due to mold deformation,non-standard worker operation,and other issues.This paper provides a new solution for quality control and finished product quality inspection in the production process of prefabricated components based on visual recognition and BIM technology.Through the analysis on experimental results and measured deviation data,it is shown that 3D laser projection technology can quickly locate and verify the key information,such as steel bars,embedded parts,and reserved holes in prefabricated components.3D scanning technology can effectively identify and quantify the size and reserved embedded position deviation of prefabricated components.This integrated technology can provide support for lean manufacturing of prefabricated components,improve the production,quality,and efficiency of prefabricated components,and has broad application prospects and potential in the intelligent manufacturing process of prefabricated buildings.
