wood, paper tube
I belong to the astronomical circle. The Astronomical Circle produces a planetarium every year at the school festival. Since the planetarium is made of corrugated cardboard, it becomes worn out due to the influence of moisture during storage. It's no longer usable after a year.
To solve this, I decided to design a new planetarium dome that does not use cardboard. I designed a sustainable planetarium dome with paper tubes and wood and cloth. Easy to assemble with 2 types of paper tubes and 3 types of joint parts.
Joint
Based on the angles and lengths calculated using 3D CAD, the joints were designed and a laser cutter was used to produce the full-scale wooden joints required for the 6 m diameter dome structure.
Air Circulation
As the inside of the dome will be a space that requires ventilation, I designed air holes on the top of the dome and on the ground surface with the floor for more efficient air circulation.
This creates a difference between the internal and external temperatures when people enter the dome, and the design allows air circulation due to the temperature difference to occur naturally.
The dome-shaped structure was constructed using 3D CAD, taking into account the loads on the hemispherical shape.
