Bird's nest building patent

The National Stadium "Bird's Nest", the main venue of the Beijing Olympic Games, not only left wonderful memories for spectators and athletes, but also won the favor of top international experts and scholars in building technology. Yesterday, the International Welding Society awarded the highest international welding award "Hugo grella Award" 20 10 to the Bird's Nest in Beijing. The National Stadium is the only award-winning project in this year's grand prize.

This award is the first time in the field of steel structure welding in China. The Bird's Nest won the prize, which broke the history of monopoly of welded structure awards in western countries for the first time. /new _ detail . ASP？ classid = 3 & ampid=40

The National Stadium uses 48,000 tons of steel and more than 2,000 tons of welding materials, and the weld seam of steel structure reaches 300,000 linear meters. Since the start of construction, scientific and technical personnel have made great breakthroughs in steelmaking, welding, steel structure unloading and other fields, realized the complete localization of Q460E-Z35 high-strength steel, and won the national construction method certification, national invention patent, national utility model patent and Beijing Science and Technology Award for many times. Many papers 10 written by the engineering construction technical team, such as Application Research on Low Temperature Welding Technology of National Stadium Steel Structure and Winter Welding Construction Technology of National Stadium Steel Structure, have been published in professional magazines at home and abroad.
