摘要:装配式预制构件较传统现浇构件构造复杂，存在构件拆分工作量大、预制构件种类多及建模操作繁琐等问题。此外，预制构件蕴含大量的参数信息，对BIM技术的信息应用与管理能力提出了更高的要求。针对以上问题，本文以桁架钢筋混凝土叠合板为例，借助于Revit内置可视化编程插件Dynamo对Revit进行二次开发，结合参数化、模数化、标准化及工程实用性的理念，创建了系列叠合板参数化应用程序。其中主要包括叠合板的智能化批量拆分、参数化批量建模以及外形尺寸信息单智能导出三个模块，同时对构件参数信息及程序功能进行了集成。最后，将本程序应用于某棚户区改造项目中，极大地简化了叠合板拆分、建模与质量检验工作流程，提高了设计及施工阶段的工作效率。

Abstract: Prefabricated components are more complicated than traditional cast-in-place components, due to the large workload of component splitting, too many types of components, and tedious modeling work. In addition, they contain a large amount of parametric information, which puts higher demands on the information application and management capabilities of BIM. To address the above problems, following the principles of parameterization, modularization, standardization, and engineering practicality, the present paper creates a parametric application for precast concrete composite slabs with rebar trusses based on Revit with the help of its built-in visual programming plug-in Dynamo. The application mainly includes three modules: intelligent batch splitting, batch parametric modeling, and intelligent export of dimension information sheets of precast concrete composite slabs with rebar trusses. At the same time, split component parametric information is integrated. Finally, the application is applied to a shantytown renovation project, which greatly simplifies the workflow of splitting, modeling, and quality inspection, and improves the efficiency of the design and construction phases.
