Description

Technical Field

[0001] This utility model relates to the field of tubular truss design and installation structure technology, and in particular to a pin connection structure between a tubular truss and a steel column that is easy to construct. Background Technology

[0002] Large-span tubular trusses are characterized by their aesthetic appeal, ease of fabrication and installation, high structural stability, high roof stiffness, and cost-effectiveness, and are widely used in public buildings such as stadiums, airports, railway stations, and exhibition halls. The connection nodes between the tubular truss and steel columns are crucial for ensuring the stability and safety of the entire structure. Due to their ability to perfectly replicate the mechanical model of hinged connections, their high strength and stability, as well as their aesthetic appeal, ease of construction, and simple structure, pin-joint nodes are widely used in large-span tubular truss structures.

[0003] Currently, pin connection nodes typically consist of several main parts, including a connecting plate, a pin, a pin washer, and a nut.

[0004] Since large-span tubular truss structures generally require high-altitude installation, there are usually two methods for the construction and installation of traditional pin-connection nodes: 1) Weld the connecting lugs to the supporting steel structure first, and then connect the roof steel structure to the supporting steel structure on site using pins; 2) Assemble the pins and their connecting lugs to the roof steel structure first, and then weld the pin lugs to the supporting steel structure on site.

[0005] The current "Steel Structure Design Standard" stipulates that the center of the pin hole should be located on the centerline of the ear plate, and the difference between the hole diameter and the main diameter should not exceed 1mm. Method 1) places extremely high precision requirements on the construction of the supporting steel structure and the roof steel structure. In method 2), the pin joint is a critical node, requiring welding work to be performed at heights, which not only increases the welding workload but also cannot fully guarantee the welding quality. Both methods suffer from problems such as unstable connections, large on-site welding workload, complex construction, extremely high precision requirements, and difficult maintenance.
