【摘要】 装配式预制构件的使用在我国具有极其广泛的应用前景,但受制于深化设计环节效率不高、模型信息传递失真、施工装配返工现象频出等问题,装配式建筑在我国的发展并不顺畅。为了使装配式建筑得到更好的发展,需要解决装配式建筑深化设计遗漏以及信息化传递问题,从而提高生产和现场安装效率,对装配式混凝土工业化建筑体系的发展意义重大。本文整体行文思路是,首先分析传统模型驱动BIM在建模和修改模型效率以及模型数据传递方面的劣势,提出数据驱动BIM的新思路,然后基于构件数据化模型(CDM)理论研究装配式预制构件参数化设计方法来改善以上问题,最后结合实际项目来体现该方法在建立模型以及设计纠偏所带来的便利和价值,为我国BIM发展提供新的思路。(1)首先从框架结构预制构件入手,分析预制叠合梁、预制叠合板、预制柱构件各自的组成规律,拆解梳理后搭建预制构件数据库,形成预制叠合梁、板、柱CDM,为“数据驱动BIM”提供数据基础。(2)然后对比分析常用的参数化编程软件优缺点,选择Grasshopper作为本文研究的参数化工具,为“数据驱动BIM”提供驱动工具平台。根据规范图集要求,从几何形状、配筋、预留预埋三个层次编写预制叠合梁、板、柱参数化程序,通过读取CDM数据表格,自动生成对应信息化模型,从而实现“数据驱动BIM”。(3)最后结合装配式框架结构项目来说明该参数化设计方法如何应用到实际项目中,并为深化设计纠偏和增效带来价值。因此本文提出的基于CDM的装配式预制构件参数化设计方法具有一定的理论意义和应用价值,可有效解决装配式预制构件快速模型建立、修改、可视化模型管理以及信息数据传递等问题,也为后期更加深入和系统性的基于CDM标准的预制构件参数化设计方法研究提供了思路和参考价值。更多还原

【Abstract】 The use of prefabricated components has extremely broad application prospects in our country.However,due to problems such as low efficiency in the deepening of the design process,distortion of model information transmission,and frequent rework of construction and assembly,the development of prefabricated buildings in my country is not smooth.In order to achieve better development of prefabricated buildings,it is necessary to resolve the omissions in the deepened design of prefabricated buildings and the problem of information transmission,so as to improve the efficiency of production and on-site installation,which is of great significance to the development of the prefabricated concrete industrialized building system.The overall idea of ??this article is to first analyze the disadvantages of traditional model-driven BIM in terms of modeling and modification model efficiency and model data transmission,propose a new idea of ??data-driven BIM,and then study prefabricated components based on the component data model(CDM)theory Parametric design methods to improve the above problems,and finally combined with actual projects to apply the method in the establishment of models and design correction of the convenience and value brought about to provide new ideas for the development of my country’s BIM.(1)Start with the prefabricated components of the frame structure,analyze the respective composition rules of prefabricated beams,prefabricated slabs,and prefabricated column components,disassemble and sort out the prefabricated components database,form prefabricated beams,slabs,and columns CDM,which is "data driven BIM" Provide a data basis.(2)Then compare and analyze the advantages and disadvantages of commonly used parametric programming software,choose Grasshopper as the parametric tool studied in this paper,and provide a driving tool platform for "data-driven BIM".According to the requirements of the standard atlas,the prefabricated beam,slab,and column parameterization program is written from the three levels of geometry,reinforcement,and reserved embedded.By reading the CDM data table,the corresponding information model is automatically generated,thereby achieving"data-driven" BIM".(3)Finally,it is combined with the prefabricated frame structure project to explain how the parametric design method is applied to the actual project,and it will bring value to the deepening of design correction and efficiency enhancement.Therefore,the CDM-based parametric design method of prefabricated components proposed in this paper has certain theoretical significance and application value,and can effectively solve the problems of rapid model establishment,modification,visual model management and information data transmission of prefabricated components.More in-depth and systematic research on the parametric design method of prefabricated components based on the CDM standard provides ideas and reference value.更多还原
