Steel box girder whole two-end hoisting linear control system and welding seam included angle control method
According to the steel box girder overall two-end hoisting linear control system and the welding seam included angle control method, a plurality of control frames are arranged on the upper portion of a steel box girder, a plurality of hydraulic cylinders are arranged between the control frames and the steel box girder in a hinged mode, and hydraulic oil is supplied to the hydraulic cylinders through a hydraulic source; when two-end hoisting construction is carried out on the whole steel box girder, if an included angle exists in a welding seam at the girder end of the steel box girder, hydraulic oil is input into the hydraulic cylinder through the hydraulic source, and the hydraulic cylinder applies tension or pressure load between the steel box girder and the linear control frame to actively control the line type of the steel box girder; the linear change of the steel box girder can change the welding seam included angle at the end of the steel box girder, and the linear change of the steel box girder is actively controlled and adjusted to finally eliminate the welding seam included angle at the end of the steel box girder and ensure the parallelism of the welding seam, so that the final bridge forming quality of a steel box girder bridge is ensured, and the technical problem of the whole two-end hoisting construction process of the steel box girder is solved.
一种钢箱梁整体两端吊装线型控制系统及焊缝夹角控制方法，在钢箱梁上部设置了若干控制架，在控制架与钢箱梁之间铰接设置有若干液压缸，液压缸由液压源为其供给液压油；当钢箱梁整体进行两端吊装施工时，若发现钢箱梁梁端的焊缝存在夹角时，通过液压源向液压缸输入液压油，液压缸在钢箱梁与线型控制架之间施加拉力或压力荷载，对钢箱梁线型做主动控制；钢箱梁线型的变化会改变钢箱梁梁端的焊缝夹角，通过主动控制调整钢箱梁线型变化大小，最终消除钢箱梁梁端的焊缝夹角，确保焊缝的平行，从而保证钢箱梁桥梁的最终成桥质量，解决了钢箱梁整体两端吊装施工工艺的技术难题。
