Stable-rotation net rack support

Abstract

The invention relates to the technical field of large-span building structures, and particularly relates to a stable-rotation net rack support. The stable-rotation net rack support comprises a positioning support, a supporting rib plate, a spherical joint and a net rack movable end, wherein the positioning support is provided with a supporting groove matched with the spherical joint; the spherical joint is provided with a connecting cavity; the net rack movable end is welded to the connecting cavity; the supporting rib plate is connected with the net rack movable end through a hoop; the supporting rib plate comprises an upper rib plate, a lower rib plate, a first positioning bolt and a first positioning nut; the lower rib plate is slidably connected with the upper rib plate; the lower rib plate is provided with a linear channel; the first positioning bolt is fixedly connected with the upper rib plate; and the first positioning bolt penetrates through the linear channel to be in threaded connection with the first positioning nut. The whole net rack can rotate smoothly with the spherical joint as a fulcrum, the workload and equipment investment increased due to installation and adjustment are greatly reduced, the net rack structure rotates in place in one step, the rotation amplitude of the spherical joint is prevented from being adjusted in the rotation process, and the operation process is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of large-span building structures, in particular to a stably rotating grid support. Background technique [0002] Large-span building structures are mainly used in theaters, stadiums, exhibition halls, great halls, airports and other large public buildings in civil buildings. In industrial buildings, they are mainly used in aircraft assembly workshops, hangars and other long-span workshops. Large-span building structures include grid structure, reticulated shell structure, suspension cable structure, truss structure, membrane structure, thin shell structure and other basic spatial structures and various combined spatial structures. During the installation process of the large-span grid structure, it is usually necessary to process and adjust the installation position on the ground. If the entire grid structure is moved by hoisting and other equipment, it is not only difficult to arrange hoisting and other eq...

AI Technical Summary

Problems solved by technology

During the installation process of the large-span grid structure, it is usually necessary to process and adjust the installation position on the ground. If the entire grid structure is moved by hoisting and other equipment, it is not only difficult to arrange hoisting and other equipment on site, but also increase the workload of other equipment. Moreover, after the installation position on the ground is handled, it is difficult to accurately transfer the grid structure to the installation position again, which greatly increases the workload of the large-span grid structure and the investment in personnel and equipment
