【摘要】：近年来，建筑信息建模（BIM）技术逐步成为计算机辅助建筑设计研究的重要分支。建筑信息建模平台对于工程数据信息的智能化集成功能使其在建筑全生命周期——设计、施工和管理三个阶段具有一般软件平台无可比拟的优势。本研究以BIM平台建模方法为切入点，通过对现有理论技术与操作实践的总结归纳，针对非标准建筑围护构件，提出具有指导意义的非标准建筑围护构件深化设计与加工预处理工作的流程建议和技术方案。研究从数控加工制造理论、建筑信息建模理论两方面出发，阐述了基于BIM平台的建筑围护构件数控加工方法的理论基础，剖析了可应对非标准构件批量加工要求的建筑信息建模功能和技术特点，即不同维度、不同平台和不同属性数据信息的复合关联，进一步提出了基于BIM平台的建筑非标准围护构件数控加工方法的流程框架。对于流程框架中几何形态预处理、构件深化设计和加工数据处理与输出三组流程，研究首先从形体表面分割、构件单元制作、单元嵌入曲面和二维关联展开等方面阐释了几何形体的处理过程。随后对构件单元细部设计、材质附加、边界确定和加工信息标注等加工条件的深化设计问题进行了探讨。进而提出了以BIM软件为核心平台的构件单元分组和排样以及图形图表文件输出的过程。对于结合BIM平台的数控加工方法的应用，研究提出了三维实体模型与二维平面图纸关联绘制方法以及基于属性信息关联的数据输出的技术方案。以Revit为平台，结合Grasshopper参数化生形技术、Ecotect日照模拟技术和AutoCAD图形表达技术，通过项目方案实践，实现了由初步形态设计，到建筑构件单元的同步深化，，再到数控加工前的最终图纸表达的完整应用流程，展现了BIM技术平台应对数字化加工制造前期构件单元设计与表达过程的高效性、精确性、直观性和灵活性。最后提出了基于BIM平台的非标准建筑构件数控加工处理方法的技术优势与局限性，并对其发展趋势进行了展望。
[Abstract]:In recent years, building information modeling (BIM) technology has gradually become an important branch of computer aided architectural design.The intelligent integration function of building information modeling platform for engineering data information makes it have unparalleled advantages in the three stages of architectural life cycle design, construction and management.This research takes the BIM platform modeling method as the breakthrough point, through the summary to the existing theory technology and the operation practice, aims at the non-standard building enclosure component,This paper puts forward the flow suggestions and technical schemes for deepening the design and processing preprocessing of non-standard building envelope components.Based on the theory of NC manufacturing and the theory of building information modeling, the theoretical basis of NC machining method of building envelope components based on BIM platform is expounded.The function and technical characteristics of building information modeling which can meet the requirements of batch processing of non-standard components are analyzed, that is, the composite association of different dimensions, different platforms and different attribute data information.Furthermore, the flow frame of NC machining method for building non-standard envelope components based on BIM platform is proposed.For the three processes of geometric preprocessing, component deepening design and processing data processing and output in the process frame, the first step of the research is to divide the surface of the body and make the component unit.The process of geometric shape processing is explained in terms of element embedding surface and two-dimensional correlation expansion.Then, the further design of detail design, material addition, boundary determination and processing information marking are discussed.Furthermore, the process of component unit grouping and layout and graphic and graphic file output based on BIM software is put forward.Based on the application of NC machining method based on BIM platform, this paper presents a method of rendering 3D solid model with 2D drawings and a technical scheme of data output based on attribute information association.Taking Revit as the platform, combining with the technology of Grasshopper parameterization, the sunshine simulation technology of Grasshopper and the technique of AutoCAD graphic expression, through the practice of the project scheme, the synchronous deepening from the preliminary form design to the building component unit is realized.Then to the complete application flow of the final drawing expression before NC machining, it shows that the BIM technology platform should be efficient, accurate, intuitive and flexible in the design and expression process of the component unit in the early stage of digital machining.Finally, the technical advantages and limitations of the NC processing method of non-standard building components based on BIM platform are put forward, and its development trend is prospected.
