Clamp for high-altitude butt joint of steel pipe columns and high-altitude butt joint method of steel pipe columns
The invention discloses a fixture for high-altitude butt joint of steel pipe columns and a high-altitude butt joint method of the steel pipe columns, belongs to the field of steel structure construction, and aims to shorten the service time of a tower crane and improve the construction efficiency. The lower steel column is tightly held by the first clamping ring and the second clamping ring, and an operation platform is installed on the first clamping ring; standing on the operating platform, and fixing the adjusting screw rod on the clamping ring II; then, a second lower nut is screwed on the adjusting screw rod, and the elevation of the second lower nut is adjusted to a proper position; then, the upper steel column assembled with the third clamping ring on the ground is hoisted to and aligned with the adjusting screw to descend and penetrate through the adjusting screw to fall onto the second lower nut, and then the second upper nut is screwed; and welding after adjusting the perpendicularity and a joint gap between the lower steel column and the upper steel column. Adjustment and welding of the lower steel column and the upper steel column do not need a hoisting tool, and the service time of the hoisting tool is shortened. The clamp is used for butt joint positioning, adjustment and temporary positioning, accurate alignment can be achieved in a shorter time, and the construction period is shortened.
本发明钢管柱高空对接用卡具及钢管柱高空对接方法，属于钢结构施工领域，目的是缩减塔吊使用时间，提高施工效率。将卡环一和卡环二环抱紧下钢柱，并在卡环一上安装操作平台；站在操作平台上，将调节螺杆固定于卡环二上；接着，将下螺母二拧在调节螺杆，调节下螺母二的标高至合适位置；然后，将地面组装有卡环三的上钢柱吊装至并对准调节螺杆降落穿入调节螺杆，落至下螺母二上，然后拧紧上螺母二；调整垂直度及下钢柱与上钢柱之间的接头间隙后焊接。本发明，下钢柱和上钢柱的调节与焊接均无需吊装工具参与，减少了吊装工具的使用时间。采用卡具进行对接定位、调节以及临时定位，能在更短的时间内达到准确对位，利于缩短工期。
