Aiming at the problems of low construction efficiency and high labor intensity of traditional bridge tower steel bar engineering,a complete set of assembling construction technology of steel bar parts is put forward.The studies are carried out from three aspects:building block design,industrialized production and prefabricated construction.Firstly,the segmental steel structure of the bridge tower is partially divided.Through analyzing the structure of the three-dimensional bending steel mesh,the whole bending forming method of the plane steel mesh is proposed.Secondly,through the analysis of each production link of the steel mesh sheet,the corresponding structure of the automatic production line and the supporting production process are designed,and the steel mesh sheet is produced in the factory,which improves the processing efficiency and forming quality of the steel mesh sheet.Finally,combined with the engineering characteristics,the construction technology of steel bar parts assembly and the stiffness guarantee method of steel bar structure are put forward.The project construction shows that the complete set of assembling construction technology of steel bar parts has obtained good application effect,which improves the machining precision and quality of steel bar of bridge tower,reduces the number of construction personnel,reduces the labor intensity,and achieves the expected research and development effect.
