【摘要】：随着城镇化进程的加快,建设工程项目的规模日益扩大,建筑造型愈加复杂,建筑异面结构增多。常规的二维施工图纸往往无法满足施工的需要,造成了生产效率低下、材料浪费严重和返工较多的现象,给现场施工造成了较大的影响,也对测量工作形成了一定的挑战。BIM技术的引入使得上述问题的解决成为可能,BIM技术是促进建筑信息化的重要技术手段,贯穿于建筑生命的全周期,在设计、施工和运营管理方面一定程度上改变了常规模式和方法,可在项目相关信息集成的基础上进行信息共享和协同合作。本文以西南某机场航站楼为例,利用三维激光扫描技术获取航站楼主体结构的点云数据,并在对点云数据进行点云拼接、点云滤波和点云精简等数据处理的基础上,采用数据驱动法进行三维建模并构建BIM模型,最终将模型应用于现场的装修吊顶施工安装。实践表明,基于点云的BIM技术具有较强的工程适用性,在相似的造型复杂、异面结构多的大型项目中有较强的应用价值。本文主要工作和成果如下:(1)阐述了三维扫描技术的特点、扫描流程以及相应的注意事项,利用三维扫描仪对机场航站楼扫描了95站,获得了机场航站楼B、D指廊主体结构的点云数据。(2)结合点云数据处理理论,对航站楼的点云数据进行包括点云拼接、点云滤波和点云精简等处理,重点分析了点云精简的方法,得到了机场航站楼B、D指廊主体结构的点云成果。(3)在点云成果的基础上,采用数据驱动法进行三维建模,提取了机场航站楼B、D指廊主体结构的粱、柱子和球节点等主要部件,并根据装修吊顶的需求构建BIM模型,主要包括吊顶需要的主龙骨、副龙骨和相应的属性信息。(4)BIM模型成果成功地应用于机场航站楼的装修吊顶施工安装,主要用于指导材料下单、构件预制管理、施工图纸输出,大大提高了工作效率,节约了材料,减少浪费,缩短工期。
[Abstract]:With the accelerated process of urbanization, the scale of the construction project is increasing, the architectural modeling is more complex and the structure of the building is increasing. The conventional two-dimensional construction drawings can not meet the needs of the construction, resulting in the low production efficiency, the serious waste of materials and more rework, which have greatly influenced the construction of the field, and also have caused great influence on the field construction. The measurement work has formed a certain challenge and the introduction of.BIM technology makes the solution of the above problems possible. BIM technology is an important technical means to promote building information. It runs through the whole cycle of building life, and changes the conventional mode and method to some extent in the aspects of design, construction and operation management, and can be integrated in the related information of the project. Based on the information sharing and cooperation cooperation, this paper takes an airport terminal in Southwest China as an example to use 3D laser scanning technology to obtain the point cloud data of the main structure of the terminal, and on the basis of point cloud splicing, point cloud filtering and point cloud simplification, the data drive method is used to model and construct the three-dimensional model. The BIM model is built, and the model is finally applied to the construction and installation of the decoration ceiling. The practice shows that the BIM technology based on point cloud has strong engineering applicability, and has a strong application value in the large projects with complex modeling and multi surface structure. The main work and fruit are as follows: (1) the characteristics of 3D scanning technology are expounded. Drawing flow and corresponding notices, using three-dimensional scanner to scan the airport terminal 95 stations, obtain the point cloud data of the main structure of the airport terminal B, D digital porch. (2) combining point cloud data processing theory, the point cloud data of the terminal building include point cloud splicing, point cloud filtering and point cloud simplification, and point cloud essence is analyzed. In the method of Jane, we get the point cloud results of the main structure of B, D, the main structure of the airport terminal. (3) on the basis of the results of the point cloud, the data drive method is used for 3D modeling, and the main parts of the airport terminal building B, the main parts of the main structure of the D corridor, the pillar and the ball node are extracted, and the BIM model is built according to the needs of the decoration ceiling, which mainly includes the need of the ceiling. The main keel, the auxiliary keel and the corresponding attribute information. (4) the results of the BIM model are successfully applied to the construction and installation of the decoration ceiling of the airport terminal building. It is mainly used to guide the materials under single, prefabrication management, and the output of the construction drawings, which greatly improves the working efficiency, saves the material, reduces the waste and shortens the time limit.
