The structure is mainly composed of the steel beam, steel column, steel truss and other components made of sectional steel and steel plate, and adopts rust removal and rust prevention technology such as silanization, pure manganese phosphating, washing and drying, galvanizing. Welding, bolts or rivets are usually used to connect between each component or part. Because its self weight is lighter, and the construction is simple, it is widely used in large factory, stadium, super high-rise, bridge and other fields. Steel structure is easy to rust, and general steel structure is rusted, galvanized or painted, and is maintained regularly.

[0003] In steel structure construction, steel column and steel beam are usually welded or bolted, for example, I-beam, during the connecting process of I-beam, the connecting steel plate with bolt hole is usually placed on the web and flange of I-beam, and the bolt is used to penetrate and connect, two groups of I-beams are connected by the connecting steel plate, but the joint of I-beam is not completely covered, for example, the utility model patent with the authorization announcement number CN202298920U discloses a steel structure connecting structure, which comprises a bearing beam, the left side of the bearing beam is provided with a left ear connecting plate, and the right side of the bearing beam is provided with a right ear connecting plate, the cross section of the left ear connecting plate and the right ear connecting plate is all in the shape of I-beam, the left ear connecting plate is fixedly connected with the left steel beam, and the right ear connecting plate is fixedly connected with the right steel beam, the left steel beam and the right steel beam are both I-beams, the upper side of the connecting position of the left ear connecting plate and the left steel beam and the upper side of the connecting position of the right ear connecting plate and the right steel beam are both provided with a supporting plate, and the left ear connecting plate, the left steel beam, the right ear connecting plate and the right steel beam are all connected with the supporting plate through a plurality of bolts; in the patent, the connecting joint between I-beams is not covered.

[0004] Utility model patent CN220035724U discloses a steel structure connection structure, including a fixing plate. A fixing steel beam is welded to the side of the fixing plate.
