Arched bolt spherical reticulated shell mounting method
The invention discloses a mounting method for an arched bolt spherical reticulated shell, belongs to the field of net rack construction, and aims to realize high-efficiency and low-cost mounting. The latticed shell is divided into a plurality of basic units, and each basic unit comprises two pairs of adjacent supports and an arched net rack between the two pairs of supports; firstly, in the span direction of a basic unit, a lower chord ball at one end of a net rack is movably arranged on a support on the corresponding side to serve as a mounting fulcrum with the center of the lower chord ball as the rotating center; then, the small splicing units are spliced on the ground in the span direction of the basic units with the installation supporting points as starting points, when the net rack splicing ends make contact with the ground, the net rack splicing ends are hoisted on the rear sides of the splicing ends with the installation supporting points as rotating points, and forward splicing continues till the net shell is installed on the opposite side supports of the whole arch; and finally, fixing the lower chord balls at the two ends of the net rack respectively. The basic units are installed on the ground, the risk of high-altitude operation is avoided, and the safety is higher; more scaffolds do not need to be erected, so that the construction period and the related cost of the scaffolds are saved.
本发明拱形螺栓球网壳安装方法,属于网架施工领域,目的是实现高效且成本低安装。网壳划分为多个基本单元,基本单元包括两副相邻的支座以及两副支座之间的拱形网架;首先,沿基本单元的跨度方向,将网架一端的下弦球以其球心为转动中心,活动设置于对应侧的支座上作为安装支点;接着,以安装支点为起点,沿基本单元跨度方向在地面拼装小拼单元,网架拼装端接触地面时,以安装支点为转动点,在拼装端的后侧吊起网架拼装端,继续向前拼装,直至网壳安装至整个拱的对边支座;最后,将网架两端的下弦球分别进行固定。本发明实现了基本单元在地面进行安装,规避了高空作业风险,安全性更高;无需搭设较多的脚手架,节约了施工周期与脚手架相关费用。
