Climbing mechanism replacement stay bar CFRP cable dome and climbing mechanism embedded stay bar CFRP cable dome
In the application field of a carbon fiber composite inhaul cable in a prestressed space structure, the invention provides a jacking mechanism replacement supporting rod CFRP cable dome and a jacking mechanism embedded supporting rod CFRP cable dome, and the jacking function of a supporting rod is achieved in the mode that a jacking assembly is embedded into the supporting rod or the supporting rod is replaced. The jacking assembly comprises a rhombic jacking frame, a jacking cable, a radial cable connecting base and an annular cable connecting base, the jacking assembly replaces or is embedded into a supporting rod, tensioning of the annular cable and an inclined cable can be avoided, and the jacking assembly can be applied to the full CFRP cable dome. The endless cable is discontinuous at the corner, so that the endless cable is prevented from being stressed in the direction perpendicular to the fiber direction, and the defect that the transverse mechanical property of a cable body of the carbon fiber composite inhaul cable is poor is overcome. The jacking assembly is hinged and rotationally arranged in the radial direction of the cable dome at the joint of the radial cable and the annular cable connecting base, and additional bending moment and shearing force generated in the jacking process of the jacking mechanism are avoided.
在碳纤维复材拉索在预应力空间结构的应用领域中，本发明提供一种顶升机构置换撑杆CFRP索穹顶和顶升机构内嵌撑杆CFRP索穹顶，通过顶升组件嵌入撑杆或取替撑杆的方式，实现撑杆的顶升功能。顶升组件包括：菱形顶升框架、顶升索、径向索连接座和环索连接座，通过将本组件替代或嵌入撑杆，可避免对环索和斜索的张拉，可应用到全CFRP索穹顶中。本发明中的环索在转角处是间断非连续的，避免了环索的垂直纤维方向受力，克服了碳纤维复材拉索索体横向力学性能弱的不足。本顶升组件在与径向索和环索连接座连接处的沿索穹顶径向方向铰接转动设置，避免了顶升机构在顶升过程中产生附加弯矩和剪力。
