基于BIM的毛石装饰墙虚拟砌筑系统研制

BIM-based Virtual Building System Development for Rubble Walls

针对某工程项目对毛石装饰墙砌筑要求高导致砌筑工作效率低的问题,本研究基于BIM研制毛石装饰墙虚拟砌筑系统。研制工作以Revit为平台进行二次开发,研制了墙体导入模块、石材图像处理模块和显示模块、毛石墙虚拟砌筑模块以及石材切割图和墙体拼装图生成模块。用户在实际应用时,只需首先对各石材编号并拍照,并将石材照片导入该系统,系统即自动生成相应的矢量图;然后,用户在系统中基于从BIM模型中导入的墙信息和毛石装饰墙的数据,只需要进行移动、旋转及裁剪等交互式操作,进行毛石墙的虚拟砌筑,系统可自动生成石材切割图和墙体拼装图,用以指导施工。本系统的应用,可有效地提高高要求毛石墙砌筑的效率。

A BIM-based virtual building system is developed by customizing Autodesk Revit to increase the efficiency of building rubble walls which is of high demand. The system consists of four modules for importing walls, processing and displaying stone images, virtual construction, and generating cutting diagrams and as- sembly diagrams respectively. In practical use, firstly, users should label numbers on stones, take photos of them and then import the photos into the system, and the system will generate the vector diagrams of each stone automatically. Secondly, based on the information of walls imported from BIM model and the vector diagrams, users construct wails virtually by means of interactive operations, such as movement, rotation and cutting, and the system will generate cutting diagrams of stones and assembly diagrams of wails at the same time which can be used to guide the construction. It is verified that the system could improve the efficiency of constructing rubble walls of high demand.
