摘要:本文主要介绍了埃及新首都CBD标志塔外幕墙工程在前期设计阶段、方案优化设计阶段、工厂加工阶段、施工现场管理阶段的BIM技术应用。在本项目的幕墙设计中,我们从方案设计和系统设计阶段就采用BIM技术,旨在项目设计前期就把施工中可能会碰到的问题提前解决掉。在方案优化设计过程中,由于本项目幕墙设计造型大面积为双曲面异形设计,因此通过Rhino 6.0的可视化编程插件Grasshopper 1.0对幕墙面板的曲率进行分析,进行面板优化,将部分双曲面幕墙面板优化为平板单元幕墙,为后期施工创造便利条件,并深入分析研究了BIM技术在双曲面结构的深化设计、下料和施工中的应用。此外通过BIM技术应用,解决了幕墙深化设计难度大、加工精度要求高、施工安装管理难、运营维护难度大等难点,实现了幕墙工程的智慧建造。
Abstract: This paper mainly introduces the BIM technology application of the outer curtain wall project of the CBD Tower in the new capital of Egypt, during all different stages of preliminary design, scheme optimization design, factory processing, and construction site management. For the curtain wall design of this project, the BIM technology is adopted from the early stage of scheme design and system design, aiming at solving the problems that may be encountered in the construction in advance in the early stage of project design. In the process of scheme optimization design, considering that the most area of curtain wall in the project is designed in hyperboloid shape, the Grasshopper1.0, a visual programming plug-in of Rhino6.0, is applied to analyze the curvature of curtain wall panel and carry out panel optimization. Part of hyperbolic curtain wall panels are optimized to be flat unit curtain wall, providing convenience for following construction. The application of BIM Technology in the deepening design, material cutting and construction of hyperboloid structure is also analyzed. Additionally, the application of BIM technology also contributes to solving the problems of difficulties in curtain wall detailed design, high processing accuracy requirements, troublesome construction and installation management, and obstacles in operation and maintenance, finally realizing the intelligent construction of curtain wall project.
