Method for pulling and adjusting high-altitude position deviation in steel structure lifting process
The invention relates to a method for pulling and adjusting high-altitude position deviation in a steel structure lifting process. The method comprises the following steps that a lifting section steel truss is paused when being about to be lifted in place, a chain block is tightened, so that the lifting section steel truss returns to a normal position in the high altitude, and gaps between lower chords, gaps between the lower chords and whether horizontal projections are overlapped or not are checked; and lifters start to work, and the gaps between the lower chords and between the lower chords meet the lifting requirement through repeated alternate matching of the lifters and the chain block until the steel truss at the lifting section is lifted in place. According to the method for pulling and adjusting high-altitude position deviation in the steel structure lifting process, the chain block is arranged to assist in adjusting displacement and deformation of a butt joint opening of a lifting part, so that the high-altitude position of the lifting section pipe truss is adjusted and corrected multiple times in the lifting process, rod pieces are smoothly aligned, and the construction efficiency is improved; and the chain block is arranged on a web member of the truss to control the high-altitude horizontal position of the steel truss at the lifting section, so that the butt-joint collision of the rod pieces is avoided, and the rod pieces are smoothly.
本发明是一种钢结构提升过程中牵引调整高空位置偏移的方法，包括提升段钢桁架在即将提升到位时暂停，收紧手拉葫芦，使提升段钢桁架在高空中回到正常位置，检查下弦杆和下弦杆、下弦杆和下弦杆的间隙，是否还有水平投影重叠；提升器开始工作，通过提升器与手拉葫芦的多次交替配合，保证下弦杆和下弦杆、下弦杆和下弦杆的间隙满足提升要求，直至提升段钢桁架提升到位。该施工方法通过设置手拉葫芦辅助调整提升构件的对接口位移和变形，使提升段管桁架在提升过程中多次调整纠正其高空位置，使杆件顺利对口，提高施工效率；在桁架腹杆上设置手拉葫芦，控制提升段钢桁架的高空水平位置，避免杆件的对口碰撞，使其顺利对口合拢。
