In March of last year, a circular arch construction with a diameter of 126 meters and a height of 40 meters was completed in the United States. This is for the construction of a giant spaceship and for exhibitions. It adopts a triangular steel frame system, which is covered with 4,000 triangular aluminum plates and has an external ivory color. The interior is equipped with a glass fiber insulation board with sound absorption and heat insulation. During construction, a 67-meter-high construction tower was erected at the center of the site. The entire dome is divided into two parts, the top cover and the periphery. The 18-meter high roof is assembled first. The peripheral part was again assembled to 14 knots. Then, 10 parts of the peripheral part are lifted and put in place.
