BIM模型是异型项目施工的基础,没有一个准确、可行的三维模型施工图,很难将一个概念性的建筑变成实际的可视的实体;异型幕墙外形又极为复杂,各外形构造面及各相关连部位的相互位置与相互关系只通过一维、二维的模型与图纸很难表达,更难以指导具体的实际施工,如果没有一个直观的理论作指导,现场实际施工就成了无源之水,无本之末。本文对BIM技术在复杂异型幕墙工程中的应用进行了介绍分析,并对相关问题进行了研究与探讨。 BIM model is the basis for the construction of special-shaped projects. Without an accurate and feasible 3D model construction drawing, it is difficult to turn a conceptual building into an actual visual entity. The shape of the special-shaped curtain wall is extremely complicated. The relative position of each other with the interrelationship only through one-dimensional, two-dimensional models and drawings is difficult to express, more difficult to guide the specific actual construction, without an intuitive theory as a guide, the actual site construction has become passive Water, no end of this. In this paper, the application of BIM technology in complex shaped curtain wall engineering is introduced and analyzed, and the related problems are studied and discussed.
