[0002] With society placing a high priority on sustainable development and resource recycling, research on the re-joining of concrete components has significant practical significance. By joining discarded concrete components, we offer an innovative solution for the reuse of construction waste. This approach not only helps reduce the environmental impact of construction waste but also increases resource reuse and reduces project costs.

[0003] At the same time, we will develop prefabricated buildings, establish a prefabricated building technology system, continuously increase the proportion of prefabricated buildings in new buildings, and actively promote the development of the construction industry towards a green and environmentally friendly direction.

[0004] Whether in the process of re-splicing components or in the splicing of prefabricated components, the steel bar connection method is a key influencing factor. In the actual process, due to external forces or improper operation of embedded steel bars, the steel bars may be misplaced. The existing steel bar connection methods, such as sleeve connection and mechanical connection, are mainly used in positioning steel bars. They have high requirements on the position of steel bars. When the steel bars are misplaced, the construction is more difficult and the connection quality is difficult to guarantee, which can easily lead to insufficient bearing capacity of the spliced components and cause serious safety hazards.
