The prefabricated building means that part or all of components and parts of the building are produced in a prefabrication factory and then transported to a construction site, and the components are assembled by adopting a reliable connection mode and a mounting machine to form the building with the design and use functions. Compared with the construction of a cast-in-place structure, the prefabricated structure has the advantages of convenience in construction, high engineering progress, small influence on the surrounding environment, easiness in ensuring the quality of building components and the like. The fabricated concrete structure has positive significance for promoting the urban construction process, improving the engineering quality, promoting energy conservation and emission reduction, improving the living environment, changing the production mode of the construction industry and the like.

At present, the vertical connection of the domestic fabricated concrete structure mostly adopts steel bar sleeve grouting connection, and the steel bar butt joint connection mode is realized by inserting steel bars into metal sleeves pre-embedded in precast concrete members and pouring high-strength and micro-expansion cement-based grouting materials.

The connection node of the prefabricated part is a theoretical weak link of the prefabricated concrete structure, and the quality of the connection quality of the node directly influences the quality and the safety of the structure. However, in the actual engineering, because the operation is not standard, the water consumption exceeds the design value of the product when the grouting material is stirred, so that the water cement ratio of the grouting material is increased, even the phenomenon that the grouting material is poor in quality is caused, and the compressive strength of the grouting material is directly reduced; the conditions of slurry leakage and less grouting can occur due to low machining precision of components or improper operation of constructors, and if the grouting inside the sleeve is not full, the connection of the steel bars cannot reach the expected performance; the phenomenon that lower-section steel bars cannot be in place due to component production or field installation deviation and the phenomenon that the lower-section steel bars are cut off individually can also occur, so that no lower-section steel bars exist in the sleeve, and the sleeve cannot be connected even if the sleeve is fully grouted. When the grouting material has insufficient strength, insufficient grouting and insufficient steel bar anchoring length, the overall performance of the structure can be affected if proper treatment is not carried out, and the structure safety is adversely affected.

Therefore, it is urgently needed to develop an assembly type concrete wall body which is easy to control the joint connection quality so as to effectively control the quality of the assembly type concrete wall body in the construction process.
