High-altitude large-span single-layer reticulated shell accumulative slippage construction method
The invention relates to the technical field of steel structure grid construction, and provides a high-altitude large-span single-layer latticed shell accumulative slippage construction method which comprises the following steps that a latticed shell structure is divided into a plurality of latticed shell units, and the latticed shell units are assembled on the ground in a segmented mode; an aerial work platform is erected; a sliding track beam, a steel column and a crawler are installed; a high-altitude supporting jig frame is installed, and the first section of latticed shell unit is hoisted to the high-altitude supporting jig frame to be integrally formed; inhaul cable installation and tensioning are conducted on the first section of reticulated shell unit; the high-altitude supporting jig frame is dismantled; the crawler pushes the first section of reticulated shell unit to slide to a target position while crawling; hoisting and integral forming of a next section of reticulated shell unit are carried out until accumulative sliding of the reticulated shell structure is completed; and dismantling the aerial work platform. The construction method has the beneficial effects that the construction difficulty is low, the construction efficiency is high, the construction safety is high, the construction cost is low, and the construction quality is easy to control.
本申请涉及钢结构网架施工技术领域，提供了一种高空大跨度单层网壳累计滑移施工方法，包括以下步骤：将网壳结构划分为若干段网壳单元，在地面分段拼装；搭设高空作业平台；安装滑移轨道梁、钢柱和爬行器；安装高空支撑胎架，吊装第一段网壳单元至高空支撑胎架上整体成型；进行第一段网壳单元的拉索安装及张拉；拆除高空支撑胎架；爬行器爬行的同时推动第一段网壳单元滑移至目标位置；进行下一段网壳单元的吊装和整体成型，直至完成网壳结构的累积滑移；拆除高空作业平台。本发明的有益效果是：施工难度低、施工效率高、施工安全性高、施工成本低、施工质量易把控。
