Description

Technical Field

[0001] The utility model relates to the technical field of plant infrastructure components, in particular to a steel frame connection structure for plant expansion. Background Art

[0002] A factory building is a house used for industrial and commercial purposes that uses a cabinet or rack structure with reinforced concrete columns or steel columns to bear the load. At present, most factory buildings are steel structures. Connection refers to the connection between steel structure components or parts. Steel structure connections are commonly connected by welds, bolts or rivets. Bolt connections are divided into ordinary bolt connections and high-strength bolt connections. In addition, steel frame connection structures are required when expanding factory buildings.

[0003] The utility model with prior art publication number CN219711972U relates to a greenhouse steel frame connection structure. By pressing the limit rod, the first spring will use its own elastic potential energy to make the limit rod detach from the limit hole and enter the first hole. The second spring will use its own elastic potential energy to pop out the movable rod. The installation and disassembly of the greenhouse steel frame is relatively simple, which improves the work efficiency of the staff. The first fixed pile is lowered and inserted into the ground through the rotating shaft, and the overall stability of the greenhouse can be improved in cooperation with the second fixed pile.

[0004] However, the above device still has the following problems when in use: when the existing steel frame connection structure for factory building expansion is used, its matching connection method is single, and when the steel frame structure for factory building expansion is assembled, it cannot flexibly adapt to different assembly requirements. In addition, the main body of the existing steel frame connection structure for factory building expansion is mostly designed with solid steel structural parts. When the steel frame connection and assembly work for factory building expansion is carried out, its own weight is large and it is more laborious to use. Utility Model Content
