BIM技术在山东省会文化艺术中心大剧院双曲面壳体龙骨定位中的应用

Application of BIM in the Keel Location of Hyperboloid Shell in the Theatre of the Shandong Provincial Capital Cultural Arts Center

山东省会文化艺术中心大剧院的3个场馆均为双曲面异形建筑,为使内层竹板完成面与设计效果一致,需精确定位龙骨。由于施工过程中槽钢定位发生偏移,无法直接从设计图纸上获得龙骨位置,借助BIM建模软件搭建大剧院壳体模型,根据设计图纸,先进行竹板排布,由此反推出龙骨的空间位置,解决龙骨精确定位的施工难题。

Three venues of the Shandong Provincial Capital Cultural Arts Center are all hyperboloid shaped building. In order to ensure the completed surface of the bamboo clappers on the inner layer meet the designed style, it is necessary to locating the keels precisely. Due to the deflection of the channel steel location in the construction, the keel location can＇t be got from the design drawing. By setting up the model of theatre shell by BIM modeling software and according to the design drawing, this paper introduce the method of arranging bamboo clappers firstly, thereby anti-deducing the spatial position of the keels and solving this construction problem finally.
