Spoke type double-layer cable truss structure and lifting method thereof
The invention provides a spoke type double-layer cable truss structure and a lifting method thereof. The structure comprises a double-layer ring cable, a compression ring beam and a series of radial cable trusses arranged between the double-layer ring cable and the compression ring beam in a radial shape, wherein the double-layer ring cable comprises an upper ring cable and a lower ring cable; theradial cable trusses are triangular trusses and comprise upper radial cables, lower radial cables and masts; the inner side ends of the upper radial cables and the lower radial cables are connected with the upper ring cable and the lower ring cable through an upper ring cable clamp and a lower ring cable clamp respectively, and the outer side ends of the upper radial cables and the lower radial cables are anchored to the compression ring beam; and the masts are vertically arranged between the upper radial cables and the lower radial cables at intervals, and the top ends and the bottom ends ofthe masts are connected with the upper radial cables and the lower radial cables through radial cable clamps respectively. According to the spoke type double-layer cable truss structure and the lifting method thereof, the passive tensioning technology is adopted for tensioning the cable trusses, the key lower radial cables are selected as active tensioning cables, and other cables and rods are all passively tensioned. The spoke type double-layer cable truss structure is simple in structure, the tensioning technology is advanced, no complex joint exists, the problem that all active tensioningcannot be achieved in large-scale truss construction is effectively solved, the equipment and personnel capital is greatly saved, and the construction period is effectively shortened.
一种轮辐式双层索桁架结构及其提升方法，结构包括双层环索、压环梁以及在辐射状设于两者之间的一系列径向索桁架；双层环索包括上下环索；径向索桁架为三角桁架，包括上径向索、下经向索和桅杆；上下径向索的内侧端分别通过上环索夹、下环索夹与上环索、下环索连接，外侧端与压环梁锚接；桅杆间隔竖向设于上径向索和下经向索之间，顶底两端分别通过径向索夹与上径向索和下经向索连接。本发明采用被动张拉技术进行索桁架张拉，选择关键的下径向索作为主动张拉索，其它索和杆均被动张拉。本发明结构简单，张拉技术先进，不存在复杂节点，有效解决了大规模桁架施工中无法实现全部主动张拉的难题，极大的节省了设备和人员资本，有效缩减了工期。
