[0017] The present application will be further described in detail below in combination with the drawings and specific embodiments.

[0018] As shown in Figure 1 , Figure 2 , Figure 3 a butterfly mortise and tenon structure curb includes a curb body 1 and a butterfly mortise and tenon structure.

[0019] The butterfly mortise and tenon structure is arranged at the side end of the curb body 1, and the two adjacent curb bodies 1 are connected through the butterfly mortise and tenon structure; the butterfly mortise and tenon structure includes a butterfly tenon and a mortise 2; the mortise 2 is arranged at the side end of the curb body 1; the two ends of the butterfly tenon are respectively inserted into the mortises 2 of the two adjacent curb bodies 1, and the middle part of the butterfly tenon is located between the two adjacent curb bodies 1.

[0020] As shown in Figure 2 , the butterfly tenon includes a butterfly body and butterfly wings arranged at both sides of the butterfly body; the butterfly wings 4 are inserted and cooperated with the mortises 2; the butterfly body 3 is located between the two adjacent curb bodies 1.

[0021] AsFigure 1 As shown, the mortise 2 is arranged at the edge where the side end of the curb body 1 intersects with the bottom. The mortise 2 comprises a side end opening and a bottom opening; the side end opening is arranged at the side end of the curb body 1, and the bottom opening is arranged at the bottom of the curb body 1. The bottom opening is a trapezoidal opening; the long bottom side of the trapezoidal opening is arranged away from the side end opening, and the short bottom side of the trapezoidal opening is arranged close to the side end opening.

[0022] The wing 4 is embedded in the mortise 2 from the trapezoidal opening; the horizontal cross-sectional shape of the wing 4 is adapted to the contour of the mortise 2. The horizontal cross-sectional shape of the wing 4 is also trapezoidal, which can be embedded in the mortise 2 from the bottom of the curb body 1, and since the bottom opening is a trapezoidal opening, the wing 4 embedded in the mortise 2 cannot be pulled out horizontally, thereby ensuring the connection stability of the adjacent two curb bodies 1.

[0023] In some embodiments, the body 3 and the wing 4 are integrally formed. The two opposite side ends of the body are respectively connected with one wing 4, and the distance between the two opposite side ends is the target gap width between the adjacent two curb bodies 1. The design thickness of the body 3 determines the gap width between the two curb bodies 1. Different thicknesses of the body 3 can be designed according to different engineering requirements.

[0024] The butterfly-shaped mortise and tenon structure can be a concrete prefabricated part or a plastic prefabricated part of other materials with the same reference numerals as the curb body 1.

[0025] In some embodiments, the side wall of the body 3 is provided with a plurality of recessed holes, or the body 3 is in the shape of honeycomb briquettes, so that when the adjacent curb bodies 1 are filled with cement mortar, the cement mortar can enter the recessed holes or the pores of the honeycomb briquettes, thereby improving the connection tightness of the butterfly-shaped mortise and tenon structure and the curb body 1.

[0026] The curb body 1 is prefabricated by a mold, which comprises a bottom plate and a side plate, and the protruding trapezoidal blocks adapted to the shape of the mortise 2 are fixed on the two side edges of the bottom plate in advance. After the bottom plate and the side plate form a pouring cavity, concrete is poured into the pouring cavity, and after the concrete reaches the target strength, the mold is removed. The bottom of the curb body 1 after demolding forms the mortise 2.

[0027] The above is only a preferred embodiment of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solutions falling within the scope of the present application should be considered as falling within the protection scope of the present application. It should be noted that, for ordinary technical personnel in the technical field, some improvements and decorations without departing from the principles of the present application should also be considered as falling within the protection scope of the present application.
