Large-span grid structure high-precision positioning and mounting method
The invention provides a high-precision positioning and installing method for a large-span grid structure, and belongs to the technical field of large-span grid installing.The high-precision positioning and installing method for the large-span grid structure comprises the steps that the design size and the actual size of a first-section grid are checked; carrying out preliminary hoisting and hoisting condition analysis on the first section of the net rack; performing high-precision difference adjustment on the first section of the net rack; fixedly connecting and mounting the first section of the net rack; splicing and mounting the subsequent net racks in sequence; wherein the operation step of sequentially splicing and mounting the subsequent net racks adopts the same step as that in the first-section net rack mounting method for mounting; the method comprises the following steps: checking the size of a first-section net rack before hoisting; in the hoisting process, the positions of the four actually-measured corner points are compared with the positions of the corresponding corner points in the design drawing in real time; the large-span net rack can be installed with high precision, and the installed large-span net rack can easily meet the design requirement.
本发明提供了一种大跨度网架结构高精度定位及安装方法，属于大跨度网架安装技术领域，该大跨度网架结构高精度定位及安装方法，包括：将首段网架的设计尺寸与实际尺寸进行校对；对首段网架进行初步吊装及吊装情况分析；对首段网架进行高精度调差；对首段网架进行固结安装；对后续网架进行依次拼接安装；其中，对后续网架进行依次拼接安装的操作步骤采用与首段网架安装方法中相同的步骤进行安装；本发明通过对吊装前的首段网架尺寸进行校对；以及在吊装过程中通过实际测量四个角点的位置与设计图纸中对应角点的位置进行实时比对；能够高精度的对大跨度网架进行安装，安装后的大跨度网架易满足设计要求。
