Segmented hoisting construction method for large-span spherical crown-shaped net rack structure
The invention discloses a segmented hoisting construction method for a large-span spherical crown-shaped net rack structure. A spherical crown-shaped net rack is installed by adopting a layered and segmented hoisting method, and after a first segment of net rack assembly unit of each layer is hoisted, firstly, two back-pulling type cable ropes are arranged on the first segment of net rack assemblyunit, and the two cable ropes are spaced by a certain distance; secondly, hoisting is sequentially carried out from the next segment of net rack assembly unit, and after each segment of net rack assembly unit is hoisted, one back-pulling type cable rope is arranged on the segment of net rack assembly unit; and then, the cable rope in the middle position is removed until the segment of net rack assembly unit forms a section of radian, and all the cable ropes are removed; and finally, the subsequent net rack assembly unit is continuously hoisted until the layer of net rack is assembled. The method is mainly used for preventing the segmented net rack from being warped downwards, and the construction method is convenient, fast, safe and efficient. The aerial operation time is shortened, and the safety risk is reduced. The use efficiency of large hoisting equipment is improved, and the method is more economical than conventional installation.
本发明公开了一种大跨度球冠形网架结构分段吊装施工方法，采用分层分段的吊装方法安装球冠形网架，每层第一段网架组装单元吊装后，首先，在第一段网架组装单元上设置两根背拉式缆风绳，两根缆风绳间隔一端距离；其次，依次从下一段网架组装单元吊装，每吊装一段网架组装单元后，均在该段网架组装单元上设置一根背拉式缆风绳；然后，拆除中间位置的缆风绳，直至该层网架组装单元形成一段弧度后，拆除所有的缆风绳；最后，继续吊装后续网架组装单元，直至该层网架拼装完成。本方法主要用于防止分段网架的下挠，施工方法方便快捷、安全高效。减少了高空作业时间，降低了安全风险。提高了大型吊装设备的使用效率，较常规安装更经济。
