Large-span single-layer spherical reticulated shell high-altitude mounting and integral lifting combined mounting method
The invention discloses a large-span single-layer spherical reticulated shell high-altitude mounting and integral lifting combined mounting method which comprises the following steps: dividing a spherical reticulated shell structure into a lifting part and a non-lifting part, dividing all reticulated shell structures of the lifting part and the non-lifting part into a plurality of small splicing units, and splicing on the ground; the small splicing units of the non-lifting part are sequentially hoisted to the installation position, high-altitude installation is conducted through a high-altitude installation jig frame, the small splicing units of the lifting part are hoisted to the assembly position, and the reticulated shell of the lifting part is assembled through a pre-installed assembly jig frame; the lifting part reticulated shell is integrally lifted to the mounting position through a hydraulic lifter of the lifting system and is connected with the non-lifting part reticulated shell in a closed mode, and the whole spherical reticulated shell is formed; and the mounted reticulated shell is unloaded. According to the high-altitude splicing and integral lifting combined mounting method for the large-span single-layer spherical reticulated shell, the construction measure cost for erecting an all-round scaffold or a steel structure supporting platform is greatly reduced, and the cost is effectively reduced.
本发明公开了一种大跨度单层球面网壳高空安装及整体提升组合安装方法，将球面网壳结构分为提升部分和非提升部分，将提升部分和非提升部分的所有网壳结构均划分为若干小拼单元，并进行地面拼装；依次将非提升部分小拼单元吊装至安装位置并借助高空安装胎架进行高空安装，将提升部分小拼单元吊装至组装位置并借助预先安装好的组装胎架进行提升部分网壳的组装；利用提升系统液压提升器将提升部分网壳整体提升至安装位置，并与非提升部分网壳合拢连接，形成球面网壳整体；对安装完毕的网壳进行卸载。该方案所采用的大跨度单层球面网壳高空拼装和整体提升组合安装方法，大大减少搭设满堂脚手架或钢结构支撑平台的施工措施费用，有效降低了成本。
