基于BIM和三维激光扫描仪的GRG多曲面弧形吊顶材料验收

Acceptance Inspection of GRG Multi-Surface Arc Shaped Suspended Ceiling Based on BIM and 3-D Laser Scanner

针对敦煌大剧院项目观众厅复杂的多曲面弧形GRG(玻璃纤维加强石膏板)吊顶验收问题进行了研究。以新型科技设备三维激光扫描仪与BIM技术运用相结合,改变了传统验收方式,即通过逆向建立BIM现场实际模型并与设计模型相对比,进行误差分析,保证了工程施工验收质量,具有一定的推广价值。

This paper conducts a research on the acceptance inspection of complicated multi-surface arc GRG （Glass Fiber Reinforced Gypsum） suspended ceiling in auditorium of Dunhuang of Grand Theatre project. The combined application of new technical equipment of 3-D laser scanner and BIM technology has changed the traditional way of acceptance inspection, that is, through the reverse establishment of BIM site actual model and making it to compare with the design model, then an error analysis is carried out accordingly. It ensures the acceptance quality of project construction and has certain promotional value.
