Construction method of spatial umbrella-shaped reticulated shell structure
The invention discloses a construction method of a spatial umbrella-shaped reticulated shell structure, and solves the technical problems of high appearance quality control difficulty, large high-altitude auxiliary operation quantity and high potential safety hazard of operation of workers when a conventional high-altitude assembling method is adopted to mount a spatial reticulated shell steel structure in the prior art. The umbrella reticulated shell structure is decomposed into the main steel column, the distribution beam combination unit and the reticulated shell unit, the reticulated shell unit is decomposed into the multiple splicing units, and machining and splicing of the main steel column, the distribution beam combination unit and the splicing units are completed in a factory; after on-site lofting, the assembling units are assembled, checked and welded into a first reticulated shell unit and a second reticulated shell unit, the first reticulated shell unit and the second reticulated shell unit are hoisted and installed respectively, and the umbrella body reticulated shell structure is measured, rechecked, welded and polished. The method can effectively reduce the appearance quality control difficulty during the construction of the spatial umbrella-shaped reticulated shell structure, reduce the high-altitude operation amount and the high-altitude operation safety risk of workers, improve the working efficiency and the mounting precision, shorten the construction period and guarantee the overall construction progress.
本发明公开了一种空间伞型网壳结构施工方法，解决现有技术采用常规高空散拼法安装空间网壳钢结构存在外观质量控制难度高、高空辅助作业量大、工人作业安全隐患高的技术问题。本发明将伞体网壳结构分解成主体钢柱、分配梁组合单元和网壳单元，网壳单元分解成若干个拼装单元并在工厂完成主体钢柱、分配梁组合单元和各拼装单元的加工拼装，现场放样后将拼装单元进行拼装、校核、焊接成网壳单元一和网壳单元二，分别起吊安装网壳单元一和网壳单元二，对伞体网壳结构进行测量复核、焊接、打磨。本发明可有效降低空间伞型网壳结构施工时外观质量控制难度，降低高空作业量及工人高空作业安全风险，提高工效及安装精度，缩短施工周期保证整体施工进度。
