Splicing method for side span steel box girder segments
The invention discloses an assembling method for side span steel box girder segments. The method comprises the steps that 1, N steel box girder segments are vertically transported to an assembling site; 2, sequentially hoisting the first steel box girder section to the (N-1) th steel box girder section, placing the steel box girder sections on sliding brackets respectively, and then sliding to reserve girder storage positions of subsequent girder sections respectively; 3, the Nth steel box girder section is hoisted to the position above the side span girder falling position, and the (N-1) th steel box girder section slides towards the small mileage side so that the Nth steel box girder section and the (N-1) th steel box girder section can be welded into a whole after being aligned up and down, fourthly, the assembled steel box girder sections are hoisted through a vertical hoisting station, so that at least a space for assembling the next section is reserved below the assembled steel box girder sections, and the closest steel box girder section is slid towards the small mileage till the closest steel box girder section is aligned with the assembled steel box girder sections up and down and then welded; and 5, the step 4 is circulated until all the steel box girder sections are welded into a whole. The problem that the suspension bridge side span steel box girder is difficult to assemble in a limited site plane is solved.
本发明公开一种边跨钢箱梁节段的拼装方法，包括：步骤1、将N个钢箱梁节段竖立运输至拼装现场；步骤2、依次起吊第一个钢箱梁节段至第N‑1个钢箱梁节段并分别放置在滑移支架上，再分别滑移留出后续梁段的存梁位置；步骤3、起吊第N个钢箱梁节段至边跨落梁位置的上空，将第N‑1个钢箱梁节段向小里程侧滑移使第N个钢箱梁节段和第N‑1个钢箱梁节段上下对准后焊接为一个整体，步骤4、利用竖向提升站起吊拼装后的钢箱梁节段使其下方至少留出下一节拼装的空间，将最近一个钢箱梁节段向小里程侧滑移至与拼装好的钢箱梁节段上下对准后焊接；步骤5、循环步骤4直至将所有的钢箱梁节段焊接为一个整体，解决了悬索桥边跨钢箱梁在有限场地平面拼装困难的问题。
