Background Art

[0002] Steel grid structures are currently a common roofing style for large-scale stadiums, industrial plants, theaters, and bus lounges in China. This innovative structural approach relies on the inherent load-bearing properties of the steel structure. Steel columns are connected and supported by bolts, creating a network of diverse roof spaces. The steel grid structure's forms are unrestrained and expansive. It combines the rhythmic beauty of classical architecture with the romanticism of modern art. Consequently, an increasing number of architects are leveraging its robustness and artistic qualities to design and construct large roof frameworks. This novel and aesthetically pleasing grid structure has created a new visual identity for modern architecture. From an artistic perspective, the grid structure's diverse and varied forms add a touch of artistic flair to people's production and living spaces. Spatial grid structures also offer advantages such as lightweight construction materials and easy installation. Furthermore, because the building materials are subjected to combined loads, they possess the unique benefit of excellent seismic resistance. The steel grid structure is a unique and remarkable addition to the vast garden of modern architectural science. Over the past decade, it has been widely used and promoted in my country.

How to speed up the connection speed of such large-diameter sleeves in cramped working conditions, reduce the time workers spend at high altitude and the time they work, and improve work quality. With the widespread application of grid structures, such problems have become increasingly prominent. The present invention is proposed based on the above research background, and aims to provide a large-diameter sleeve connection quick-tightening installation device in a large ball net structure and its use method to overcome the above-mentioned defects and meet the needs of ball net construction.
