Description

Technical Field

[0001] The utility model relates to the field of arc-shaped cantilevered grid frames, in particular to an arc-shaped cantilevered grid frame roof structure. Background Art

[0002] The spherical grid is a special spatial structure. It is based on a sphere and is composed of many rods arranged and combined according to a specific rule to form a solid and beautiful spherical space frame. This structural form has been widely used in the field of modern architecture and has become an important load-bearing structure for large buildings such as stadiums, exhibition centers, and industrial plants. In the spherical grid, the ball node and the rod are the key elements that constitute its basic unit. As the basic force-bearing unit, the ball node can effectively disperse and transfer the load; while the rod, as the compression zone, is connected to the ball node by welding or bolting to form a stable spatial structure. This structural form not only has a beautiful appearance, but also can realize the flexible use of the internal space of the building. In the actual construction process, it is necessary to set a steel skeleton light roof panel roof on the top of the arc cantilever grid, but its safety and reliability are difficult to guarantee. Therefore, how to develop a new type of arc cantilever grid roof structure has become a problem that needs to be solved by technicians in this field. Utility Model Content
