High-strength prefabricated part

The high-strength prefabricated part comprises a prefabricated part body, an I-shaped steel bar and an assembling and connecting beam, the prefabricated part body comprises a decoration panel and an assembling and connecting panel which are integrally formed, the surface of the decoration panel is of a smooth smooth surface structure, and a plurality of meshing grooves are formed in the surface of the assembling and connecting panel. The section shape of the I-shaped steel bar is twice that of the meshing groove, and the side face of the assembling panel is provided with a plurality of through insertion holes matched with the assembling beam structure in size. According to the utility model, the novel split type prefabricated part structure is arranged, and the prefabricated part main body, the I-shaped steel bars and the assembling stringers are matched with one another for splicing and assembling, so that the surface of the prefabricated part main body is free from any exposed penetrating structure in the p
