Two vertically adjacent permanent templates are clamped with the groove 12 through the protrusion 11 and can be firmly combined together, and the combination is more stable due to the gravity action of the permanent templates. In two horizontally adjacent permanent formworks (assumed as a first permanent formwork and a second permanent formwork), the first connecting plate 21 of the first permanent formwork is connected to one end (i.e. the inner side) of the second permanent formwork, while the second connecting plate 22 of the second permanent formwork is connected to the other end (i.e. the outer side) of the first permanent formwork, and one side of the first permanent formwork, the other side of the second permanent formwork, the first connecting plate 21 of the first permanent formwork and the second connecting plate 22 of the second permanent formwork surround to form a second casting cavity 6.
