After the two prefabricated building component bodies are plugged into the socket and the plug post is inserted into the tapered hole, providing compression for the positioning plug, so that the positioning plug is inserted into the socket and positioning is achieved.

[0004] During the assembly process of existing prefabricated components, external fixing components are generally required to assist in the assembly, which greatly increases the complexity of the assembly of prefabricated components. In addition, various connection structures need to be installed inside the existing prefabricated components during the prefabrication process, which greatly increases the difficulty and cost of prefabrication. In addition, the existing prefabricated components need to be prefabricated accordingly according to the needs of use, such as sound insulation or heat insulation, which greatly reduces the adaptability of the prefabricated components. In addition, during the prefabrication and assembly process of concrete prefabricated components, the subsequently poured concrete cannot form a strong adhesion with the prefabricated components, and stratification will occur, thereby greatly reducing the strength of the assembly.

[0005] Therefore, it is necessary to invent a multifunctional prefabricated component and an assembly method to solve the above problems. Summary of the Invention

At this time, the through hole 1 203, the through hole 2 302 and the through hole 3 404 of the prefabricated part 001 can be penetrated with the corresponding threaded steel bar 101 by hoisting, and the prefabricated part 001 can be placed on the foundation; S2: connect the step block 301 on one side of the newly hoisted prefabricated component 001 with the step groove 201 on one side of the erected prefabricated component 001 from top to bottom, and ensure that it penetrates the corresponding threaded steel bar 101 to complete the horizontal erection of the prefabricated component 001; S3: At this time, the threaded steel bar 101 is erected upwards through the construction binding process of the threaded steel bar 101, and the prefabricated parts 001 are continuously hoisted so that the prefabricated parts 001 can be stacked and erected. After the threaded steel bar 101 is sleeved, it needs to be basically in the center of the through hole 1 203, the through hole 2 302 and the through hole 3 404. In the erection process, the corresponding materials need to be placed in the placement cavity 1 204, the placement cavity 2 304 and the placement cavity 3 402 according to the needs. S4: Finally, the concrete is transported into the prefabricated component 001 along the through hole 1 203, the through hole 2 302 and the through hole 3 404, and the concrete can be transported to the corresponding parts inside the prefabricated component 001 according to the connecting cavity 1 205, the connecting cavity 2 305 and the connecting cavity 3 406, thereby completing the assembly of the entire prefabricated component.

[0036] like Figure 1-8 As shown, by hoisting a group of prefabricated parts 001, the through hole 1 203, the through hole 2 302 and the through hole 3 404 above the prefabricated parts are first penetrated and connected with the threaded steel bar 101 above the foundation. At this time, the other group of prefabricated parts 001 is hoisted in the same way, and the step block 301 on one side is ensured to be docked with the step groove 201 of the other group of prefabricated parts 001. At this time, the positioning block 1 307 of the step block 301 is just docked with the positioning hole 1 206, and through this method, The subsequent prefabricated part 001 is built by the method, and the threaded steel bar 101 is tied to extend the threaded steel bar 101 upward. At this time, the subsequent prefabricated part 001 is erected upward by hoisting, so that the positioning hole 2 403 and the positioning block 2 409 are connected, and the pressing block 408 and the placement cavity 3 402 are connected. During the assembly process, the corresponding sound insulation or heat insulation materials can be placed in the placement cavity 1 204, the placement cavity 2 304 and the placement cavity 3 402 according to the needs. When the assembly is completed, the sound insulation or heat insulation materials can be placed in the placement cavity 1 204, the placement cavity 2 304 and the placement cavity 3 402 according to the needs. Concrete is poured into the through hole 1 203, the through hole 2 302 and the through hole 3 404, and the concrete flows into the various spaces after the prefabricated part 001 is assembled through the connecting cavity 1 205, the connecting cavity 2 305 and the connecting cavity 3 406. After solidification, the solidified concrete between the trapezoidal groove 1 208 and the trapezoidal groove 2 306 will form a structure, which greatly enhances the strength of the connection. The same is true for the connecting groove 1 207 and the connecting groove 2 308, as well as the connecting groove 3 405 and the connecting groove 4 410. Through this structure, the assembly between the prefabricated parts 001 can be completed quickly, and no auxiliary connecting device is required during the assembly process, which greatly reduces the difficulty of lifting and matching the seams. In the prefabrication process of this prefabricated part 001, no additional connecting components are required, thereby greatly reducing the difficulty and cost of prefabrication. According to the needs of use, corresponding auxiliary materials can be added inside it to improve the overall adaptability. After the subsequent concrete pouring and molding, the structure formed by its solidification can greatly increase the overall connection strength.

[0037] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
