Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering, in particular to a V-shaped rectangular steel pipe column foot node structure. Background Art

[0002] In the early days, the design of traditional building column base nodes was often relatively simple and might not fully meet the high requirements of modern buildings for structural strength, stability and durability. Especially in high-rise buildings, large-span bridges and complex structural systems, traditional node designs often face challenges. The V-shaped rectangular steel tube column base node structure was born in this context. It adopts a V-shaped design, which can effectively disperse the load and improve the bearing capacity of the node. This construction method is not only suitable for various types of buildings and projects, but can also be customized and optimized according to specific needs to meet specific design requirements.

[0003] With the advancement of science and technology and the continuous accumulation of engineering practice, the V-shaped rectangular steel pipe column base node structure has been widely used and promoted. It has become an indispensable part of modern architecture and engineering, providing a strong guarantee for the safety and stability of various complex structures.

[0004] However, in the existing results, the force transmission between the steel column and the semicircular tube shell is not direct. The steel column must first transmit force to the horizontally mounted semicircular tube shell. The semicircular tube shell and the steel column are in a nearly vertical T-shaped contact relationship. The axial force and bending moment of the steel column must be transmitted to the vertical stiffening ribs through the bending and shear resistance of the outer side of the semicircular tube shell, rather than its axial tensile or compressive resistance. Then, the force is transmitted to the embedded steel plate and foundation. In this force transmission process, the bearing capacity of the semicircular tube shell needs to be specially calculated. The calculation model is complex and not easy to calculate clearly, and there are certain safety hazards. In view of this, we propose a V-shaped rectangular steel tube column foot node structure.
