[0002] The steel bar project occupies a crucial position in the construction industry. Especially in large-scale buildings and special projects, such as nuclear power projects, factors such as its quality, efficiency, and cost have attracted much attention. However, traditional steel bar connection methods often have low efficiency and are prone to errors, and cannot meet the strict requirements of modern construction projects. Although the construction method of steel bar componentization helps to improve construction efficiency and project quality, there are still many problems in its mechanical connection technology, such as complex operation and unstable quality.

[0003] A compound steel bar joint (patent number ZL96218592.2) is disclosed in the prior art. By friction welding a taper thread screw or a taper thread sleeve at the end parts of two steel bars to be connected respectively, the two steel bars are connected to form a steel bar joint with threads; or by friction welding a thread screw at both ends of the steel bar and connecting it with a corresponding internal thread sleeve to form a steel bar joint. The friction welding is firm, the on-site operation speed is fast, the operation is simple, and the butt joint of embedded steel bars can be solved.

[0004] Although the application of friction welding in steel bar connection in the above prior art can solve the problem of steel bar connection, after the friction-welded steel bar joint is welded, the welded part will protrude with burrs, which needs to be polished manually. And when there are deviations in the actual project using the friction-welded steel bar joint method, the steel bar connection position cannot be adjusted, and the coaxiality of the butt joint cannot be maintained.

[0005] In view of the above factors, an adjustable combined steel bar connecting joint is specially designed. The external sleeve covers the internal sleeve and the first locking nut. Rotate the first locking nut to lock the first connection end, and the second locking nut cooperates with the screw rod to lock the second connection end, thus completing the whole connection process.
