Analysis and Discussion of Manufacturing Process of Composite Steel Box Girders
The girder is the main load-bearing structure of lifting appliances,and with the gradual in-crease of the lifting capacity of the appliance,the height of girder section is getting higher and higher,while the high girder section brings sig-nificant difficulties in transport,manufacturing and installation.Composite steel box girders can effectively solve the above problems.Com-posite steel box girders have the advantages of small manufacturing and transport units and easy connection.The structural form of composite steel box girders is currently rare in China.Camber control,welding deforma-tion control,superposition surface matching control and bolt perforation rate control are the key technical difficulties in the manufacturing process of composite steel box girders.The manufacturing process of composite steel box girders is analyzed and discussed.
