Large-span dome reticulated shell support-free jig frame overhanging installation method
The invention relates to a large-span dome reticulated shell support-free jig frame overhanging installation method which comprises the following steps: constructing annular reticulated shells layer by layer from bottom to top to form a dome reticulated shell; and each layer of annular reticulated shell is formed by splicing a plurality of net rack single bodies at the mounting positions. Construction facilities required by the support-free jig frame overhanging installation method are mainly lifting overhead working trucks, and large hoisting or jacking equipment and a large number of jig frames are not needed. According to the support-free jig frame overhanging installation method for the large-span dome reticulated shell, in each step of construction, the dome reticulated shell which is not installed completely is of a stable structure supported on the ground, the requirement of hoisting or jacking of a large-scale structure for hoisting equipment is avoided, multiple potential risks of high-altitude installation of the large-scale structure are avoided, and the construction efficiency is improved. The method has the advantages of simplicity, feasibility, convenience and reliability.
本发明涉及一种大跨度穹顶网壳无支撑胎架悬伸安装方法，包括自下至上逐层施工环状网壳，以构成穹顶网壳；每层所述环状网壳由若干网架单体在安装位拼装完成。无支撑胎架悬伸安装方法所需的施工设施主要为升降高空作业车，无需大型起吊或顶升设备与大量胎架。本发明提出的大跨度穹顶网壳无支撑胎架悬伸安装方法，实现了在施工的每一个步骤中，未完成安装的穹顶网架都是支撑于地面的稳定结构，避免了大型结构起吊或顶升对起重设备的要求，以及大型结构高空安装的诸多潜在危险，具有简单易行、便捷可靠的优点。
