In this case, in order to form a more precise coupling angle, the bending angle of the second member 120 is set to 60 degrees, and the fitting plate 140 having the angle of 60 degrees between the adjacent second members 120 is formed In addition, six spaces S having an angle of 60 degrees can be additionally formed, and each steel pipe member 200 can be quickly joined with a joining angle of 60 degrees to achieve a hexagonal geometric building envelope structure have.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. And will be apparent to those skilled in the art.
