Traction lifting installation method of inclined inhaul cable hanging sphere structure
The invention discloses a traction lifting installation method for a slant inhaul cable hanging sphere structure, which comprises the following steps: firstly, assembling the sphere structure on the ground, arranging traction tools on two sides of an upper anchor point of a slant inhaul cable, and arranging lug plates perpendicular to the ground; according to shape-finding and force-finding iterative analysis, the configuration and the cable force of the design state and the initial state of the sphere are determined; secondly, based on simulation analysis of the whole traction and lifting process, reversely presetting coordinates of an anchor point on a main structure, actually measuring coordinates of an upper port and a lower port in combination with a three-dimensional scanning technology, and accurately determining the length of a zero-stress cable; and finally, a plurality of fixed-length ropes are synchronously and obliquely pulled at different speeds, so that the sphere is lifted and installed to the initial state configuration, and after the additional dead load is applied, the sphere structure is downwarped to the design state configuration. According to the method, the design state, configuration and cable force of the aerial hanging sphere structure can be effectively achieved, construction measures are greatly saved, the high-altitude operation risk is reduced, and the construction period is shortened.
本发明公开了一种斜向拉索吊挂球体结构的牵引提升安装方法，首先球体结构在地面拼装，牵引工装设置在斜向拉索上锚点两侧，耳板均垂直于大地设置；根据找形找力迭代分析，确定球体的设计态及初始态的位形和索力；然后基于牵引提升全过程仿真分析，对主结构上锚点坐标反向预调，并结合三维扫描技术实测上下端口坐标，精准确定零应力索长；最后通过异速、同步斜向牵引若干根定长索使球体提升安装至初始态位形，待附加恒载施加后，球体结构下挠至设计态位形。本发明能够有效实现空中吊挂球体结构设计态位形和索力，并大大节约施工措施，减少高空作业风险，缩短施工工期。
