Research on Integrated Steel Bar Design and Processing for BIM-based Railway Prefabricated Box Girder
Aiming at the problems of low design level and backward production mode in steel bar works of railway prefabricated box girder,this paper studies the integrated steel bar design and processing for BIM-based railway prefabricated box girder.This paper establishes the integrated steel bar design theory of railway prefabricated box girder,and uses Tekla software to complete the BIM design of girder body and refined design of steel bar,which mainly solves the problems of interference between steel bar and prestressed pipeline,anchorage and drainage opening;it uses technologies such as big data,cloud platform and loT to develop data conversion software,production management system and workshop control system,and collaborates with equipment manufacturers to develop complete sets of special equipment for automatic steel bar processing.The field application in the steel bar works of box girder of Tianjin-Weifang Railway shows that this study can improve the automation level of steel bar works of railway prefabricated box girder and provide a reference for other similar works.
