Special-shaped space truss mounting method
The invention relates to the technical field of large-span steel structure installation, and discloses a special-shaped space truss installation method. A special-shaped space net rack is divided into a support area net rack, a plurality of lifting area net racks and a plurality of inlaying area net racks, the support area net rack and the lifting area net racks are connected through the inlaying area net racks, every two adjacent lifting area net racks are connected through the inlaying area net racks, and a temporary supporting system is built on an existing supporting structure. Mounting support area net racks on the temporary supporting system in a spare part manner, splicing single lifting area net racks in a spare part manner by adopting an original position and original posture manner, lifting the single lifting area net racks to a preset height, completing mounting of inlaying area net racks on the peripheries of the lifting area net racks, and then unloading lifting points of the single lifting area net racks to complete mounting of the inlaying area net racks on the peripheries of the lifting area net racks. And lifting of all the lifting area net racks and installation of the inlaying area net racks are completed in sequence. According to the method, the large-span fold-line-shaped ultrahigh heavy special-shaped space truss can be smoothly installed with high work efficiency, high precision and low cost.
本发明涉及大跨度钢结构安装技术领域，公开一种异形空间网架安装方法。将异形空间网架划分为支座区域网架、若干个提升区域网架和若干个嵌补区域网架，支座区域网架和提升区域网架之间以及相邻两个提升区域网架之间分别通过嵌补区域网架连接，在既有支承结构上搭建临时支撑系统，在临时支撑系统上散件安装支座区域网架，采用原位置原姿态方式散件拼装单个提升区域网架，提升单个提升区域网架至预设高度，完成提升区域网架周边的嵌补区域网架的安装，然后，卸载单个提升区域网架的提升点，依次完成所有提升区域网架的提升以及嵌补区域网架的安装。本发明以高工效、高精度、低成本顺利实现了大跨度折线形的超高重型异形空间网架的顺利安装。
