Description

Technical Field

[0001] This utility model relates to the field of rebar sleeve technology, specifically to an adaptive variable diameter rebar sleeve anti-loosening locking ring. Background Technology

[0002] In the field of construction engineering, steel reinforcement connections are a core component ensuring structural safety and stability, and the reliability and efficiency of the technology are of paramount importance. With the continuous advancement of the construction industry, increasingly stringent requirements have been placed on the quality, efficiency, and adaptability of steel reinforcement connections.

[0003] Axial cold-press connection of reinforcing bars is a mechanical connection method that uses a cold extrusion press to deform the connecting sleeve, thereby combining the sleeve with the two reinforcing bars inserted into it. Through extrusion, the sleeve undergoes plastic deformation, tightly gripping the transverse and longitudinal ribs of the reinforcing bars, thereby realizing the transfer of force between the two reinforcing bars.

[0004] Existing rebar sleeve connection structures typically use compression sleeves to compress the connecting sleeves when connecting rebars, thereby securing the connection between the rebars. However, this method, relying solely on compression, is prone to loosening under complex conditions such as long-term vibration and alternating loads. Once the compression sleeve loosens, the mechanical properties of the rebar connection decrease, affecting the safety and stability of the entire building structure. Therefore, an adaptive variable diameter rebar sleeve anti-loosening locking ring is proposed. Utility Model Content

Once the extrusion sleeve loosens, the mechanical properties of the rebar connection will decrease, thereby affecting the safety and stability of the entire building structure.
