Continuous steel box girder swivel structure and construction method
The invention relates to a continuous steel box girder swivel structure and a construction method, the continuous steel box girder swivel structure comprises a steel box girder, the two ends of the top of the steel box girder are fixedly provided with pulling plates, the steel box girder is fixedly provided with a base, and the base is movably connected with a hinged support through a pin shaft; one end of the tower is fixed to the hinged support, an upper anchor beam is fixed to the end, away from the hinged support, of the tower, and a sling is anchored to the upper anchor beam and the pulling plate. The hinged support at the bottom of the tower structure is connected with the main body steel box girder base through the pin shaft, so that the problem that the bottom bending moment is too large in the tensioning or rotating process of the tower is solved, detail adjustment of the tower structure is facilitated, and the construction efficiency is improved. The problem that a tower is stressed unevenly due to the fact that large unbalanced bending moment is generated due to the cable force difference during rotation construction of the asymmetric steel box girder can be solved, construction equipment is simple and clear, and the construction difficulty is small in the operation process.
本发明涉及一种连续钢箱梁转体结构及施工方法，其包括：钢箱梁，其顶部两端固定有拉板，所述钢箱梁上固定有底座，所述底座上通过销轴活动连接有铰座；塔架，其一端固定于所述铰座，所述塔架远离述铰座的一端固定有上锚梁，所述上锚梁与所述拉板锚固有吊索。通过将塔架结构底部铰座与主体钢箱梁底座通过销轴连接，减少了塔架在张拉或转体过程中，底部弯矩过大的问题，方便塔架结构进行细部调整，可以解决非对称钢箱梁在转体施工时因索力差产生较大不平衡弯矩而导致的塔架受力不均的问题，且施工设备简洁明了，在操作过程中施工难度较小。
