The invention discloses an all-prefabricated splicing type floor. The floor is formed by splicing two or more prefabricated floors. A tooth groove structure is adopted at the splicing position of thetwo prefabricated floors, and the two prefabricated floors are engaged together through a tooth groove. Two or more connecting fixing parts are arranged between the two prefabricated floors. By the adoption of the above all-prefabricated splicing type floor, the two prefabricated floors are spliced through the tooth groove structure, the multiple connecting fixing parts are used for connection, the face interior shear stiffness and bearing capability of the floor are greatly improved, the face interior flexural bearing capability of the all-assembly type floor can be improved through the fixing connecting parts, it is ensured that compatibility of deformation of the exterior of the face of the floor is ensured, the phenomenon that a splicing joint of the floor is cracked, and the use attractiveness is affected is avoided, in addition, the structure is simple, and field construction is relatively convenient.
