Description

Technical Field

[0001] The utility model relates to the technical field of steel beam connection, in particular to an adjustable node connection mechanism for a weather-resistant structural steel beam. Background Art

[0002] Weather-resistant structural steel beams refer to steel beam structures with good corrosion resistance and fatigue resistance in natural environments. Such steel beams are usually used in outdoor bridges, buildings and other fields to cope with severe weather and environmental conditions. The characteristic of weather-resistant structural steel beams is that specific alloy elements are added to the steel to improve its corrosion resistance and fatigue resistance. In addition, the manufacturing process of weather-resistant structural steel beams is also different. Special welding processes and surface treatment technologies are usually used to ensure their stability and safety during long-term use. When weather-resistant structural steel beams are connected to steel columns, a node connection mechanism is required to support the steel beams and steel columns to prevent the connection nodes from falling off and breaking.

[0003] However, the existing node connection mechanisms are all welded and fixed at the supports of steel beams and steel support columns and cannot be adjusted. However, this structure will permanently fix the steel beams. When the steel beams need to be replaced, the steel support columns and steel beams need to be cut at the same time. The high temperature during cutting will cause the characteristics of the steel beams and steel support columns to change, making the connection nodes unusable. Utility Model Content
