塔吊超长距离小角度扶墙技术

Buttress Technology of Tower Crane with Extra-Long Distance and Small Angle

金华万佛塔为钢混高耸结构,施工中塔吊必须先行满足内筒结构的吊装需要,导致塔吊布设时扶墙距离超长,角度明显偏小,受力不合理。为此,采用增设钢结构支撑架,并通过软件建模、结构复算,最终顺利地解决了塔吊超长距离、小角度扶墙的安装难题,为类似工程施工提供了借鉴。

Jinhua Wanfo Tower is a steel-concrete towering structure. During construction, the tower crane should firstly meet the lifting requirements of internal cylinder structure, which causes the buttress in extra-long distance and an obvious small angle with irrational stress when setting the tower crane. Therefore, the project set up additional steel structure support frames and solved the buttress installation difficulties of tower crane with ultra-long distance and small angle through software modeling and double structure calculation, which can provide references for similar projects.
