Description

Technical Field

[0001] The invention relates to the technical field of building steel structures, and in particular to a cross-rotating circular ring hexagonal column structure and a manufacturing process method thereof. Background Art

[0002] As the country vigorously promotes prefabricated buildings, more and more landmark large buildings are built with steel structures. This type of building has become an important symbol of the city due to its unique shape and structural requirements. Steel structure has become the preferred material for these landmark buildings due to its high strength, light weight and fast construction speed. The special shape and structural requirements of landmark large buildings require the use of various complex column or beam steel components during their design and construction. These steel components not only need to meet the requirements of structural force, but also meet the requirements of architectural aesthetics and functionality. For example, the cross-turn circular hexagonal column node used in some large buildings is one of the typical complex steel components. When dealing with such complex cross-turn circular hexagonal column nodes, the traditional manufacturing process cannot meet the corresponding quality requirements, it is difficult to ensure the accuracy and consistency of the nodes, and it is easy to have dimensional deviations and welding defects, which affect the safety and stability of the structure. At the same time, the manufacturing difficulty is high. The geometric shape of the cross-turn circular hexagonal column node is complex. The traditional manufacturing process method requires multiple positioning and adjustments, which is difficult to operate and requires high technical level of workers. The production process is complicated. The traditional production process involves multiple processes, such as cutting, assembly, welding, etc. Each process needs to be strictly controlled, and the connection between processes is also relatively complicated, which is prone to errors. The production efficiency is low. The traditional production process method leads to a long production cycle and low production efficiency, which is difficult to meet the needs of large-scale production. Summary of the invention

[0003] The present invention provides a cross-rotating circular ring hexagonal column structure and a manufacturing method thereof, which effectively solves the quality problems, great manufacturing difficulty, cumbersome procedures and low production efficiency existing in traditional manufacturing methods by optimizing the structural form, reasonably arranging the assembly sequence and adopting an efficient welding method, so as to meet the structural force and manufacturing progress requirements of landmark large buildings.
