[0002] At present, in construction engineering, large sports stadium is mostly space grid structure, and the space grid structure mostly adopts strip and block method to install. For example, the maximum cantilever of the steel roof of a large sports stadium reaches 38m, the hoisting unit length after strip is also 38m, and the number of hoisting points of the segmented unit is relatively large. If the flat pole beam is not used to distribute, one is that the length of the steel wire rope is too long, the angle is too large, and the steel wire rope is under great stress.
