From the left, the development prototypes are shown.

























































This is the first sheet metal model.
The three vertical boards are aligned in the center to create a horizontal
The discs are put together.
At first, I had no idea about sledding or bending.
It was made from imagination in a way.
Details of the final shape will be revealed during construction.
I didn't understand.
The "sori" is a sled shaped like a Japanese sword.
"Mukuri" means a shrine or temple.
This refers to the bulge seen in the pillars.
There are two types of Skytree
Curves are included.
The sled is shaped like the apex ridge of a triangle.
The curvature passes through the center of the triangular face.
The vertical shape, carefully rotate the surface horizontally
You won't notice it unless you look at it from the side.
Because of this curvature
The Skytree has a unique shape
have.




















This is the next prototype.
The shape is pretty clear too.
Go to the construction site and see it from afar
Shoot with a telephoto lens and capture the silhouette
Measured on CAD.
You have to take pictures from at least three directions.
The exact overall shape is unclear.
Especially in the area below 100m
To reproduce the curved lines
It is important.
There are limited spaces available.
The vertical boards are simply increased to six.
was.



























This is the next prototype.
The number of vertical boards was simply increased to nine.
was.
Attaching mesh panels to surround the structure
The plan is to first put a plate on the side.
Just to see if it can be attached
I attached the board and made a prototype.
It's attached on the left side.
































Two mounting boards have been installed.
This is the status.
