Problems solved by technology
At the same time, higher requirements are put forward for the construction and installation technology of the single-layer reticulated shell structure and the corresponding construction analysis theory. The traditional high-altitude on-site splicing operation not only has a low safety factor, but also costs a lot of high-altitude on-site splicing. A series of construction technology research has very important application value

Embodiment Construction
[0026] The invention is suitable for the construction of cylindrical reticulated shell structures supported by two longitudinal sides, especially for theaters and stadiums with square or rectangular planes, and the construction site is narrow, the main enclosure structure has been constructed, and it is difficult for large-scale hoisting machinery to solve the problem. For shell construction, especially for projects with tight construction schedules and difficult access, reticulated shell construction must be carried out in parallel with civil construction and three-dimensional crossing operations.
[0027] like figure 1 As shown, the rods of the sliding unit 21 (22, 23) are unloaded and manufactured in the processing plant and then transported to the construction site. The tower crane is used to lift the loose parts to the assembled tire frame 1 for assembly, and assemble them on the assembled tire frame 1. After the sliding unit 21 is formed, the sliding track 3 is installed...

The invention discloses a single-layer reticulated shell structure high-altitude inclined rail accumulated slide moving construction method, which is characterized by comprising the following concrete construction steps that 1, slide moving units are designed; 2, a corresponding splicing tire frame is erected and arranged according to the designed slide moving units; 3, slide moving rails are installed; 4, the first slide moving unit is spliced and welded, and after the completion, the slide moving unit is disengaged from the splicing tire frame; 5, the first slide moving unit slides and moves, and the slide moving distance is the length of one slide moving unit; 6, the second slide moving unit is spliced and welded; 7, the first and second slide moving units are in butt joint, and after the butt joint completion, the first and second slide moving units integrally move and slide; 8, the step-by-step splicing is carried out until the splicing of all slide moving units is completed; 9, the slide moving rails are dismounted, the tire frame is spliced, and the cost for building a great number of scaffolds is omitted.
Description
technical field [0001] The invention relates to a construction method for accumulative slippage of a high-altitude inclined rail with a single-layer reticulated shell structure. Background technique [0002] Among the many types of space structures, the single-layer reticulated shell structure has been greatly applied and developed because of its light weight and high structural efficiency. At the same time, higher requirements are put forward for the construction and installation technology of the single-layer reticulated shell structure and the corresponding construction analysis theory. The traditional high-altitude on-site splicing operation not only has a low safety factor, but also costs a lot of high-altitude on-site splicing. The series of construction technology research has very important application value. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a single-layer reticulated shell structure high-...
