【摘要】 全张力结构索穹顶是国内空间结构专家一直关注的一种新型高效结构。目前,国内对索穹顶施工技术研究开展较少。结合我国无锡新区科技交流中心首个刚性屋面索穹顶工程,介绍其施工技术研究及创新安装方法。重点介绍了无支架提升索杆累积安装技术,脊索索夹抗滑力试验及紧固工艺,拉索张拉以及刚性屋面檩条高空安装技术。指出拉索张拉采用双控原则:控制结构内力和变形。更多还原

【Abstract】 The tensile structure of cable dome is a new kind of efficient structure which has been concerned by the domestic space structure experts.At present,the construction technology of cable dome is little in China.Combining with the first rigid roof cable dome engineering of Wuxi Science and Technology Communications Center,the research on construction technology and installation method for cable dome structure is introduced.The no-stent accumulative installation technology for hoisting rodcable, anti-sliding experiment and fastening technology for cable clamp,tensioning of cable and purlin installation at high altitude are indicated in detail.It is pointed out that internal force and deformation should be controlled in cable tensioning.更多还原
