The project as a whole is a complex three-dimensional curved surface modeling, covering an area of more than 2,200 square meters, the top elevation of 8.9 meters, the height of the eaves structure of 4 meters, the total amount of steel structure 200 tons. Its core design highlight is a 14-meter diameter ring daylighting roof, extending outward through a spiral radial layout, with a maximum radius of 28 meters.The inner and outer ring structure adopts rectangular square pipe bending technology, in which the outer ring is precisely spliced into a circle by 8 custom-made curved steel beams, and the center ring adopts hot bending technology to achieve high-precision curved surface modeling.
