A plurality of ring support frameworks 103 are arranged inside the steel frame connection sleeve 1. The ring support frameworks 103 and the steel frame connection sleeve 1 are set as an integral structure. A hard rubber ring 1032 is arranged inside the ring support framework 103. The hard rubber ring 1032 is connected to the ring support framework 103 through a slot. The I-beam 2 extends into the ring support framework 103 of the steel frame connection sleeve 1.

The through-holes 104 penetrate and extend into the steel frame connection sleeve 1. Rib slots 1031 are arranged on the outer surface of the ring support framework 103;

[0023] In this embodiment, the I-beam 2 for bridge steel members is inserted into the ring support framework 103 inside the steel frame connection sleeve 1. The ring support framework 103 plays a role in supporting and limiting the I-beam 2, preventing the I-beam 2 from being displaced due to external forces at the connection part. The steel frame connection sleeve 1 can protect the connection part of the I-beam 2, effectively avoiding the erosion of rainwater on the interface of the I-beam 2 and ensuring the stability of the bridge structure;

[0024] A dust-proof sleeve plate 201 is arranged on the outer side of the I-beam 2. The dust-proof sleeve plate 201 is connected to the steel frame connecting sleeve 1 by bolts. Metal ribs 202 are arranged between the dust-proof sleeve plates 201. The metal ribs 202 are connected to the ring bracing skeleton 103 through rib slots 1031.

[0025] In this embodiment, after the I-beam 2 is docked through the dust-proof sleeve plate 201, the two sets of locking bolt 3 structures are inserted from the outside of the dust-proof sleeve plate 201, penetrate through the I-beam 2 and then pass out from the other side. Subsequently, the two ends of the locking bolt 3 are locked and fixed by the locking nuts 301, which can prevent the I-beam 2 from slipping out of the inside of the dust-proof sleeve plate 201. Finally, the metal ribs 202 are passed through the rib slots 1031 on the surface of the ring bracing skeleton 103 to enhance the lateral support of the ring bracing skeleton 103 and prevent the ring bracing skeleton 103 from deforming.

[0026] Working principle: The I-beam 2 for bridge steel members is inserted into the ring bracing skeleton 103 inside the steel frame connecting sleeve 1. The ring bracing skeleton 103 plays a role of supporting and limiting the I-beam 2, preventing the I-beam 2 from being offset and misaligned at the connection due to external forces. The steel frame connecting sleeve 1 can protect the connection of the I-beam 2, effectively avoiding the erosion of rainwater on the interface of the I-beam 2 and ensuring the stability of the bridge structure.
