It comes to architectural forms, especially for the masterpiece, one might think of the "Bird's Nest" is a steel structure, the CCTV new site, Yintai Center ... Throughout the urban construction, provided that the large, odd building in architectural form, without exception, chose steel, modern designers have a preference, the builders of love in it? I recently visited the CCTV new site project, had a conversation with the construction of three steel expert Ouyang Chao.
China's steel construction started late, high starting point
No formal conversation, Ouyang Chao first to reporters about a story. A century ago, lasted three days and three nights the fire almost the entire Chicago to ashes. Americans, however, take this opportunity to ignite the torch of architectural art. Materials of glass and steel buildings which throughout America in every state, even the chain stores became steel ...
It is reported that it was not until the mid-1980s, the Chinese steel construction is still "zero". It was at this time than in the western late decades of Chinese steel structure construction, but in a very high starting point, a very high standard, very strict requirements, a difficult start, the rapid development. China's steel construction of the starting point can be traced back to 1984, when construction of three successful first steel building in China - Shenzhen Development Center. At the time, on the battlefield of the main concrete structure of domestic construction, steel construction is virgin land. Quickly master the world's most advanced carbon dioxide gas shielded welding technology has become builders to complete the works in the hands of a diamond. So, the council of 10 welders elite east Fuso Arts. Japan's Kawasaki Steel Training Centre experts learned most of them only junior middle school education, they assert that "based on solid foundations also have to learn 3-6 months, your contract to learn of only one month, when one-third qualified one is not're wrong! "the face of humiliation, 10 Chinese welders focus on learning 7 hours every day after school after a meal to explore, learn. After 30 days, 10 Chinese guy successfully closed down. In subsequent work on the Shenzhen Development Center Building Project, they play an important role to refresh the previous record of 110 mm from the welding of 130 mm thickness, to 350 000 linear meters of weld testing and inspection of the ultrasound and Zi powder all qualified, and then to 98% of the welding reach the standards of the highest (D grade). China's steel construction will never be out of control!
