The invention relates to a construction method of a cable dome central support tower and operation platform comprehensive system, which comprises a foundation base, a tower crane body and a construction operation platform, and is characterized in that a jacking system and a tower crane jacking sleeve section are mounted on a tower crane standard section, and the tower crane standard section is mounted through the jacking system and the tower crane jacking sleeve section; one side of the tower crane lifting sleeve section is provided with a tower crane standard section inlet, and the upper end face of the tower crane lifting sleeve section is fixedly provided with a steel plate fixing cover; the construction operation platform comprises a main beam, reinforcing secondary beams and a platform steel plate, the main beam is arranged in a regular triangle shape, and each reinforcing secondary beam comprises two groups of structures arranged in a regular triangle shape in a sleeved mode and a group of structures connected in a diagonal mode through three-way connecting mechanisms. A symmetrical tying installation method can enable a middle stress component to be stable, firm, safe and reliable; the elevation control of the top construction operation platform is very accurate, and particularly, the method can play a crucial role in the overall construction quality of a large-span suspension project.
本发明涉及一种索穹顶中央支撑塔架及作业平台综合体系的施工方法,包括基础底座、塔吊机身和施工作业平台,特征在于:塔吊标准节上装有顶升系统和塔吊顶升套节,通过顶升系统和塔吊顶升套节安装塔吊标准节,塔吊顶升套节一侧上设有塔吊标准节引入口,塔吊顶升套节上端面固装有钢板固定盖;施工作业平台包括主梁、加强次梁和平台钢板,主梁呈正三角形布局,加强次梁包括两组呈正三角形内套式布局结构和一组3根通过三向连接机构对角连接结构,优点是:适用大型网状复杂的索穹顶结构,对称拉结安装方法可使中间受力构件平稳牢固,安全可靠;对于顶部施工作业平台的高程控制非常精准,尤其是对于大跨度悬空工程整体施工质量可起到至关重要的作用。
