The present invention relates to a bolt assembly-type three-dimensional structure. According to the present invention, a relay coupling tool formed as a spherical three-dimensional structure, an oblong three-dimensional structure, a polygonal three-dimensional structure, or an atypical three-dimensional structure is provided, a coupling groove is formed in the three-dimensional structure, a female screw thread structure is provided for the coupling groove, a cylindrical coupling bar having a bolt-type screw structure on one side or both sides is provided, and assembly in various forms can be performed when the relay coupling tool is connected by the use of the coupling bar. The spherical, oblong, or polygonal relay coupling tool is provided, multiple first coupling grooves are formed in the relay coupling tool, the female screw thread is formed in the first coupling groove, and the male screw thread is formed at both ends of the coupling bar to correspond to the relay coupling tool. According to the present invention, the multiple coupling grooves are formed in the relay coupling tool, the coupling bar is connected through the coupling groove, and then the three-dimensional structure is produced. Accordingly, the structure can be conveniently produced and three-dimensional structures of various shapes can be formed as toys. |
