Large-diameter steel pipe column butt joint installation construction method
The invention discloses a construction method for butt joint installation of large-diameter steel pipe columns, which comprises the following steps of: quickly keeping the central axis of a positioning tool consistent with the central axis of the large-diameter steel pipe columns through a plurality of horizontal range finders uniformly arranged on the positioning tool, and adjusting a positioning nut sleeved on a positioning bolt in a matched manner so that the levelness of the positioning tool can meet the requirement; preliminary positioning of the positioning nut relative to the lower-end steel pipe column is achieved, the initial butt joint precision of the upper-end steel pipe column is ensured, and the butt joint efficiency is improved. The positioning adjusting plate is arranged between the brackets of the upper and lower steel pipe columns, and the central axis and levelness of the steel pipe columns at the upper end after initial butt joint are finely adjusted through the horizontal adjusting bolt and the vertical adjusting bolt, so that the final butt joint precision can be ensured, and the construction quality is guaranteed; the positioning bolts, the positioning nuts and the fastening nuts are matched with the lower-end brackets and the upper-end brackets of the steel pipe columns, the upper-end steel pipe columns and the lower-end steel pipe columns which are finely adjusted are fixed, the spliced steel pipe columns are stably connected, and follow-up welding work is facilitated.
本发明公开了一种大直径钢管柱对接安装施工方法，通过定位工装上均匀设置的多个水平测距仪可快速使定位工装的中心轴与大直径钢管柱的中心轴保持一致，配合调节定位螺栓上套设的定位螺母可使定位工装的水平度满足要求，以实现定位螺母相对下端钢管柱的初步定位，确保上端钢管柱的初始对接精度，提高对接效率；通过在上下钢管柱牛腿间设置定位调节板，通过水平调节螺栓和垂直调节螺栓对初始对接后的上端钢管柱进行中心轴及水平度的微调，可确保最终对接精度，保障施工质量；采用定位螺栓、定位螺母、紧固螺母与钢管柱下端牛腿和上端牛腿相配合，将微调完成后的上端钢管柱与下端钢管柱固定，使拼接后的钢管柱稳固连接，方便后续焊接工作。
