Prefabricated tenon-and-mortise structure brick mold

The invention relates to a prefabricated tenon-and-mortise structure brick mold. The prefabricated tenon-and-mortise structure brick mold comprises a brick mold body, and a middle tenon and a middle mortise are formed in one side of the brick mold body; an end tenon and an end mortise are formed on the other side of the brick mold body; and the middle mortises and the end tenons are oppositely arranged, and the middle tenons and the end mortises are oppositely arranged. The prefabricated tenon-and-mortise structure brick mold is simple in structure and ingenious in design, and the brick mold is prefabricated in a factory; and the prefabricated tenon-and-mortise structures are constructed through the tenon-and-mortise structures of the prefabricated tenon-and-mortise structures, a stable stress system is formed after erecting is completed, and additional temporary supports or fixing pieces do not need to be arranged. The integral structure is stable through mutual mortise and tenon joint between the prefabrica
