[0002] The roofs of sports stadiums are mostly complex special-shaped structures, and steel structures are mostly used as the roof canopy system to make special-shaped outline frames. At present, the commonly used construction methods for installing steel structures in many large stadiums include high-altitude bulk method, strip or block installation method, high-altitude sliding method, overall hoisting method, overall lifting method, overall jacking method, etc. Due to the complexity of special-shaped steel structures, the hoisting construction method of the present invention adopts the high-altitude bulk method.
