Large-span net rack jacking construction process
The invention relates to a large-span net rack jacking construction process. The process comprises the following steps of calculating the jacking number and position; assembling a net rack; mounting ajacking device; reinforcing the floor; jacking the net rack, starting a hydraulic pump to enable a piston rod of a hydraulic oil cylinder to synchronously rise for one stroke, mounting a second standard knot above a first standard knot, enabling a cylinder body of the hydraulic oil cylinder to rise through oil return of the hydraulic pump, and moving a cross beam to the second standard knot to complete one stroke, repeating the net rack jacking step, stopping jacking when the net rack rises to 10-20 cm above the designed elevation; and unloading mounting, enabling the hydraulic oil cylinder to synchronously descend to drive the net rack to fall on a preset mounting base, and completing jacking construction. The process has the effects of shortening the construction period and improving the installation quality and the construction safety.
本申请涉及一种大跨度网架顶升施工工艺，其包括以下步骤，顶升数量和位置计算；网架拼装；安装顶升装置；加固楼板；网架顶升，启动液压泵使液压油缸的活塞杆同步上升一个行程，在第一个标准节的上方安装第二个标准节，液压泵回油使液压油缸的缸体上升，将横梁移动至第二个标准节，完成一个行程，重复网架顶升步骤使网架上升至设计标高以上10‑20cm时，停止顶升；卸载安装，使液压油缸同步下降带动网架落在预设安装座上，完成顶升施工。本申请具有缩短施工周期、提高安装质量和施工安全性的效果。
