[0018] The utility model will be described in detail in combination with the drawings and examples.

[0019] The prefabricated wall body, such as Figure 1 And Figure 2As shown, the structure includes a structural layer 1, which comprises a steel layer 2 with a straight cross-section and a steel layer 3 with a C-shaped cross-section. Steel layer 2 and steel layer 3 are integrally formed. An embedding groove 4 is formed on steel layer 3, facing away from steel layer 2. The width of the embedding groove 4 is equal to the thickness of steel layer 2. Concrete layers 5 are provided on both sides of steel layer 2. The opposite sides of the two concrete layers 5 are flush with the opposite sides of steel layer 3. The length of the concrete layers 5 is less than the length of steel layer 2. An insert 6 is formed at the end of steel layer 2 facing away from steel layer 3 for embedding into the embedding groove 4. The length difference between steel layer 2 and concrete layer 5 is equal to the depth of the embedding groove 4. The insert 6 has several threaded holes 7. Through holes 8 and 9 are respectively formed on the two inner walls of the embedding groove 4. All three threaded holes 7, through holes 8 and 9 are used to allow the same bolt to pass through. The number of threaded holes 7, through holes 8, and through holes 9 are equal. Both ends of through hole 8 are connected to the outside, while through hole 9 is connected to the outside at only one end. During construction, the installer 6 of one wall is embedded into the embedding groove 4 of another wall, and each threaded hole 7 on the installer 6 is coaxially set with its corresponding through hole 8 and through hole 9. The installer passes bolts through through hole 8, threaded hole 7 and through hole 9 in sequence, thereby fixing the installer 6 in the embedding groove 4, thus achieving the connection between the two adjacent wall layers. The bolt connection method makes the wall connection more stable and faster, and the connection process is not affected by the surrounding environment, ensuring the overall construction speed of the project. The structural layer 1 is made of steel, making the structural layer 1 more stable, thus making the structural strength of through hole 8, through hole 9 and threaded hole 7 set on the structural layer 1 higher, thereby ensuring the connection strength of the two wall layers.
