They are precast concrete parts in the factory and then transported to the construction site for assembly. Such components include but are not limited to building components such as walls, floors, stairs, balconies, etc. Since PC components can be produced in a factory environment, the quality can be better controlled, ensuring the strength and durability of the components, and the on-site installation speed is fast, reducing the construction time and labor costs. Therefore, PC components play an increasingly important role in the modern construction industry, promoting the development of the construction industry towards industrialization, intelligentization and greenization.

[0003] For example, a splicing structure of a PC component disclosed in the prior art with the publication number CN218149228U splices adjacent PC precast slab one and PC precast slab two in the vertical direction through the mutual cooperation of a convex block and a splicing receiving groove, and then makes the fixed cross plate and the adjacent PC precast slab be spliced horizontally by the interaction of an external splicing groove and a splicing block, ensuring to improve the integrity of the splicing.

[0004] However, the above prior art still has the following problems when in use: Although using multiple connecting mechanisms can play a splicing role on the side walls of multiple stabilizing mechanisms, since the connecting mechanisms are installed on the side walls, the force is not stable, which will further affect the strength of the entire PC component. Based on this, the utility model provides a splicing structure of PC components. Summary of the Utility Model

[0005] In order to overcome the above defects of the prior art, the utility model provides a splicing structure of PC components.
