Large-span large-fall curved surface steel net rack external expansion assembly accumulative lifting method
A large-span large-fall curved-surface steel net rack external expansion assembly accumulative lifting method comprises the steps that the position of each lifting suspension point is determined, and a plurality of lifting devices are assembled at the preset position of a main body steel structure according to the positions of the lifting suspension points; the first end of the initial grid structure is connected with corresponding lifting equipment, and the area, close to the second end, of the initial grid structure is supported through an assembling jig frame so that the second end of the initial grid structure can be kept at the first preset height; the first end of the initial grid structure is lifted to a second preset height through lifting equipment; splicing net rack unit structures at the two ends of the initial net rack structure to form a middle net rack structure; forming a final grid structure until the initial grid structure reaches a preset length; and the final grid structure is lifted to the preset elevation through lifting equipment. According to the large-span large-fall curved surface steel net rack external expansion assembling accumulation lifting method, the construction quality is high, the construction efficiency is effectively improved, the construction progress is guaranteed, and certain economic benefits are brought.
一种大跨度大落差曲面钢网架外扩拼装累积提升方法，包括：确定各提升吊点位置，根据提升吊点位置将若干提升设备装配在主体钢结构的预设位置；将初始网架结构的第一端与对应的提升设备连接，初始网架结构靠近第二端的区域通过拼装胎架进行支撑以使得初始网架结构的第二端保持在第一预设高度；通过提升设备将初始网架结构的第一端提升至第二预设高度；在初始网架结构两端拼装网架单元结构形成中间网架结构；直至初始网架结构到达预设的长度形成最终网架结构；通过提升设备将最终网架结构提升到预设标高。该大跨度大落差曲面钢网架外扩拼装累积提升方法，施工质量高，且有效提高施工效率、保证施工进度，带来一定的经济效益。
