[0002] As we all know, in recent years, with the continuous development of the modern construction industry, many new construction technologies have gradually been integrated into the construction industry. Reinforced concrete, as the main material in construction, its strength and stress resistance directly determine the engineering quality of the building. Rebar, as the supporting frame in concrete, has a more important joint. If the joint is not tight enough, the long-term load-bearing of reinforced concrete will easily lead to loose joints, resulting in cracks in the concrete, which will pose a serious threat to the quality of the project. This is especially true in applications such as tunnel reinforced concrete, where higher requirements are required.

[0003] The existing steel bar sleeves are not firm enough when the steel bars and the steel bar sleeves are installed by extrusion connection, and the fixing method is single.
