Scheme Design of Small Box Girder for Intelligent Construction
In the face of the industry development direction of building industrialization to intelligent manufacturing,the goal is to promote the intelligent construction of small box girder structure.Through investigation,it understands the difficulties of intelligent production of various processes in the current factory,and focuses on the most difficult node of automatic binding of reinforcement in the production process.Considering the development level of domestic numerical control reinforcement binding equipment in design,research&development,production&manufacturing,it is expected that there will be a variety of solutions to solve the closed plate structure with equal wall thickness&the automatic binding of stirrups in the future.It puts forward the overall scheme of reassembling the small box girder reinforcement cage into four basic reinforcement modules of roof+floor+2 webs,and subdivides it into three implementation schemes of structural measures.Taking a typical road small box girder as an example,it analyzes the structural design feasibility&process convenience of the three implementation schemes.Through comparison,it is recommended to adopt the scheme of setting sudden change section in the web of the small box girder&keeping the thickness of the bottom plate unchanged.
