AI Technical Summary
Existing pre-embedded steel bar connecting sleeves are prone to instability and reduced stability during construction due to foreign objects falling off.
A sleeve for connecting pre-embedded steel bars was designed, which uses a sleeve with an anti-rotation component and a protective component. The anti-rotation component includes an anti-rotation ring and a reinforcing ring, and the protective component includes a protective cap and a sealing plug. The anti-rotation ring increases the contact area with the concrete to prevent the sleeve from rotating, the sealing plug prevents grout from entering the sleeve, and the protective cap seals the other end of the sleeve to ensure a stable connection.
This effectively prevents grout from entering the casing, prevents the casing from rotating and falling off in the concrete, and ensures the stability and firmness of the steel reinforcement connection.

[0017] The technical scheme in the utility model will be described clearly and completely in combination with the drawings in the utility model.
[0018] Example one: refer to Figures 1-4The utility model provides a sleeve of embedded steel bar connection, including steel bar sleeve main part 100, steel bar sleeve main part 100 includes sleeve pipe 110, and the both ends of sleeve pipe 110 are through design, and the both ends of the inner surface of sleeve pipe 110 are equipped with opposite connecting threads 111, and the outer surface of sleeve pipe 110 is equipped with anti -rotation subassembly 300, and any end of sleeve pipe 110 is equipped with protection subassembly 200, and protection subassembly 200 includes protection cap 210, and protection cap 210 is located in any end of sleeve pipe 110, and the one end of protection cap 210 close to sleeve pipe 110 is fixedly installed with sealing plug 212, and sealing plug 212 and the inner wall of sleeve pipe 110 are closely combined, and the insertion end of sealing plug 212 is fixedly installed with guide head 211, and the insertion end corner of guide head 211 is arc chamfer design, and the material of protection cap 210, guide head 211 and sealing plug 212 is foam or rubber.
[0019] The working principle of the utility model embodiment one is that in the construction process, the steel bars that embedded steel and exposed steel cannot be connected simultaneously can be connected by the connecting thread 111 on the sleeve pipe 110 cooperating with the thread on the surface of embedded steel first, and then the sealing plug 212 is inserted into the other end of the sleeve pipe 110 after installation, and then the concrete is injected, and then the protection subassembly 200 and sleeve pipe 110 are separated after the concrete injection is completed, and the other connecting thread 111 on the sleeve pipe 110 and the external steel bar are connected again.
