摘要:湖南航天医院门诊外科大楼平面形状为“楔型”，内部结构中部分梁柱节点存在有多根不同方向的梁交汇于柱节点的情况，节点处钢筋密集复杂。在项目实施过程中，项目部运用BIM技术通过分层着色、合理确定钢筋参数等方法实现了钢筋在三维模式下的空间位置精确定位、三维彩色显示、工序安排、钢筋原材定尺长度优化的目的，提高了钢筋施工质量与原材料利用率。

Abstract: The surgery building of Hunan Aerospace Hospital is a wedge-shaped architecture, in which exists some beam-column joints intersected with beams from diverse directions, where the steel bars are densely distributed and highly complexed. During the construction progress, the project department adopted BIM technology, through using methods like layered coloring and reasonably determining the reinforcement parameters, thus finally achieves achieve the purposes of accurately positioning steel bars and colored displaying under 3D mode, as well as construction schedule management and optimization of steel bar length. All these work has improved the construction quality, and also increased the utilization ratio of raw materials as well.
