Bracket-free construction method of annular large cantilever cable bearing grid structure
The invention relates to a bracket-free construction method of an annular large cantilever cable bearing grid structure, and belongs to the technical field of space cable structures. The method comprises the following steps: 1, carrying out structural installation on the periphery of a steel structure; 2, laying a ring cable and installing a grommet cable clamp; 3, completing the installation of aradial cable; 4, laying and installing a mounting support frame, and then completing the steel structure installation of an upper inner top steel structure, an upper outer top steel structure and a ring beam; 5, installing an upper inner stay cable, an upper outer stay cable, and an upper bottom stay cable; 6, realizing and completing the connection of the radial cable, the ring cable clamp and astrut; 7, wholly stretching the radial cable to enable the structure to form an outer ring bed jig and separate; 8, completing the installation of an inner side inclined strut; 9, removing the upperinner stay cable, the upper outer stay cable, and the upper bottom stay cable; and 10, completing a roof, a berm and the like, and completing the construction of the whole structure. The bracket-freeconstruction method has the advantages of being rapid in installation, low in construction cost, high in construction quality, capable of reducing construction safety hazards and short in period. Theproblem of downward deformation of the front end of the roof is solved.
本发明涉及一种环形大悬挑索承网格结构的无支架施工方法，所属空间索结构技术领域，包括首先进行钢结构外围的结构安装，接着铺放环索，并安装环索索夹。再完成径向索的铺放安装。先铺设安装支撑架，然后完成上部内顶钢结构、上部外顶钢结构和环梁的钢结构安装。再安装上部内斜拉索、上部外斜拉索和上部底斜拉索。实现完成径向索、环索索夹与撑杆相连接。而后通过整体张拉张拉径向索使结构成形至外圈胎架脱离，再完成内侧斜撑杆的安装，之后拆卸上部内斜拉索、上部外斜拉索和上部底斜拉索。最后完成屋面、马道等，完成整体结构的施工。具有安装快速、施工成本低、施工质量高、减低施工安全隐患和周期短的优点。解决了屋盖前端产生向下变形的问题。
