Description

Technical Field

[0001] The utility model relates to the technical field of steel structure connection, in particular to a steel structure connection device. Background Art

[0002] Steel structure buildings are a new type of building system that breaks through the industry boundaries among the real estate industry, construction industry, and metallurgy industry, integrating into a new industrial system. This is the steel structure building system that industry insiders generally look favorably upon. Compared with traditional concrete buildings, steel structure buildings use steel plates or steel sections to replace reinforced concrete, with higher strength and better seismic resistance. Moreover, since components can be fabricated in factories and installed on-site, the construction period is greatly reduced. Due to the recyclability of steel, the generation of construction waste is reduced, making it more environmentally friendly, and it is widely used in industrial and civil buildings.

[0003] The prior art with the publication number CN113202188B discloses a steel structure quick connector. It pre-drills pin holes and coaxial through-holes on the connecting beam, symmetrically clamps two connectors on both sides of the bottom flange of the bottom beam using a clamping groove. At this time, the connecting beam is hoisted, and the bottom of the connecting beam is clamped between two pressing frames. Then, a tension bar is inserted through the coaxial through-hole, and the pressing frames are tightened by the tension bar. During the tightening process of the tension bar, the push plate is forced to slide. At this time, the bevel at the end of the push plate abuts against the hypotenuse of the moving angle block and overcomes the elastic force of the tension spring to push the moving angle block to displace, so that the docking pin on the moving angle block is inserted into the pin hole, and at the same time, the connection and locking of the web and flange of the connecting beam are completed.

[0004] Although the prior art realizes the quick connection of steel structures, the strength at the steel structure connection is poor. To solve the above technical problems, we propose a steel structure connection device. Content of the Utility Model
