Hoisting method of large-span steel structure reticulated shell roof
The invention relates to a hoisting method for a large-span steel structure reticulated shell roof. The hoisting method comprises the following steps: hoisting a steel stand column in the middle of a site; single-hoisting rotating devices are hoisted on the peripheral stand columns; manufacturing and installing a guide auxiliary ring frame; manufacturing a central annular reticulated shell; the central annular reticulated shell is hoisted, bolted and fixed; the radial main beam is hoisted, bolted and fixed; the arc reticulated shell units are hoisted, bolted and fixed; the hoisted reticulated shell is welded and fixed; manufacturing, hoisting and welding the centermost circular latticed shell; and finally, a reserved arc reticulated shell unit is manufactured, hoisted and welded. The hoisting device has the beneficial effects that the latticed shell structure is hoisted by the winch, so that the use of large machines such as crawler cranes is reduced, and the risk during construction is greatly reduced. And rotating shafts and sliding winches are additionally arranged on the central steel stand column and the peripheral stand columns, so that the lifting flexibility of the latticed shell structure can be improved. The upper, middle and lower units, the large and small arms and the like of the central steel stand column are detachable and can be repeatedly used, and resource waste of large machines and tools is avoided.
本发明涉及一种大跨度钢结构网壳屋盖的吊装方法，包括以下步骤：场地中间的钢立柱吊装；周边立柱上吊装单吊旋转装置；导向辅助环架制作安装；中心环形网壳制作；中心环形网壳吊装栓接固定；径向主梁吊装栓接固定；弧网壳单元吊装栓接固定；已吊装网壳焊接固定；最中心圆形网壳制作吊装焊接；最后预留的一个弧网壳单元制作吊装焊接。本发明的有益效果是：由卷扬机对网壳结构进行吊装，减少了履带吊等大型机器的使用，大大的降低了施工时的风险。在中心钢立柱与周边立柱上都加装了旋转转轴以及滑动卷扬机，能够提高对网壳结构吊装的灵活度。中心钢立柱的上、中、下单元以及大小臂等可拆卸且可以重复使用，避免了大型机具的资源浪费。
