摘要:某工程重竹吊顶曲面与金属屋面板曲面平行,均为双曲造型,且曲率变化多,传统的二维深化设计无法完成对双曲面的重竹吊顶分析,以实现编制合理施工方案及材料下料、精确加工的需求。工程采用建立三维空间信息模型,对整个曲面的每一个板块进行排版及矢高分析,结合材料的变形性能,选择较优的安装方法,复核碰撞,避免后续施工中误差累积、碰撞拆改或无法安装等问题,较好地保证了设计效果,节约工程造价。
Abstract: In this project, the curved surface of heavy bamboo ceiling is parallel to that of metal roof panel, both of which are in hyperbolic shapes with various curvature changes. The traditional 2D deepening design method fails to complete the analysis of double curved bamboo ceiling, let alone to achieve the need of preparing reasonable construction scheme and precise material cutting and processing. The project adopts 3D spatial BIM modeling to implement the layout and vector height analysis of each plate of the whole surface. According to the deformation performance of materials, the BIM model contributes to the selection of best installation method and composite collision detection, which problems such as error accumulation, collision, demolition or installation failure in subsequent construction. The design effect is well guaranteed, and the project cost is saved.
