关于塔体吊离排子,腾空越过塔基础时,对溜尾铜丝绳和起重滑轮组的受力分析,本文提出了比较准确的计算方法;对采用把杆吊塔,缆风绳受力计算中,如何合理地选用安全系数,以及滑轮摩阻总系数,作者根据施工经验及现场粗略试验,提供了一些参考意见;对于采用单根独脚把杆倾斜架设进行吊塔的合理性和施工中应注意的问题,以及在吊塔过程中经常出现塔尾从排子上甩落的现象,也进行了初步分析。
With respect to the analysis of the force of towering copper wire ropes and hoisting sheaves when the tower body is lifted off the row of poles and levitated over the tower foundation, a comparatively accurate calculation method is proposed in this paper. In the calculation, how to reasonably choose the safety factor and the total friction coefficient of the pulley, the author provides some reference suggestions according to the construction experience and the rough test on site. For the rationality and construction Should pay attention to the problem, as well as in the tower hanging tower often appear from the row on the off phenomenon, but also conducted a preliminary analysis.
