On September 15, hosted by China Steel Structure Association, Maanshan Iron & Steel Co., Ltd., and co-organized by the Yangtze River Delta Iron and Steel Industry Chain Development Alliance Committee, the Heavy Hot-rolled H-beam Application Seminar and the Second Meeting of the Sixth China Steel Structure Expert Committee. Maanshan Iron & Steel, which has the reputation of "A Flower in the South of the Yangtze River", was held. The theme of the meeting was: to gather talents in steel structure and lead assembly-style innovation.
Academician of Chinese Academy of Engineering, Honorary President of China Steel Structure Association, Professor Nie Jianguo of Tsinghua University, Academician of Chinese Academy of Engineering, Chief Engineer of China Communications Construction Group, Vice President of China Highway Society Zhang Xigang, Academician of Chinese Academy of Engineering, Chairman of China Steel Structure, MCC Construction Chairman Yue Qingrui of the Central Research Institute Co., Ltd. and others gathered in Maanshan Iron and Steel Co., Ltd. with nearly 300 representatives of Chinese steel structure experts from all over the country to discuss and discuss the meaning of product application. They pointed out that the domestic The first heavy-duty H-type production line has completely broken the monopoly of this foreign product in the Chinese market. It has functions comparable to similar foreign products and can meet the needs of high-rise buildings, power, chemical, bridges, airports, ships, and tunnels at home and abroad. High-end demand in other industries.
Apply steel-concrete structure to consolidate the foundation for the promotion of heavy H-beamIn the past 20 years, Maanshan Iron & Steel has developed a large number of high-tech products through independent innovation, self-accumulation and effective cooperation with relevant institutions of higher learning, which has satisfied many key projects at home and abroad. Nie Jianguo said that although the hot-rolled H-beam steel produced by Maanshan Iron & Steel has many advantages in underground engineering structure, it also faces challenges such as a wide range of fields, a large quantity and a wide range, high performance requirements, difficulty in construction, and difficulty in innovation. The reason for this understanding is that there is no best structure for engineering structures, only applicable structures. Reinforced concrete structures can take advantage of the advantages of steel and concrete to provide options for solving structural engineering problems, developing new structural systems, and realizing high-performance structures. In other words, the use of steel-concrete structure can make the structure more reasonable, reduce the use of concrete, increase the rigidity and high durability. Through the construction of some large-scale domestic projects, people in the industry will feel firsthand that the use of steel-concrete structures has realized their own complementary advantages. This is mainly reflected in the steel constraining the concrete and improving the crack resistance, and the concrete constraining the steel and improving the stability. . In terms of the application and promotion of heavy H-beam steel, we cannot fully target some major projects, but also aim at national water conservancy, renovation of dilapidated houses, underground pipe network projects, basic service projects, etc., to truly achieve mechanism innovation for large and small projects , Concept innovation, service innovation, technological innovation, construction innovation, management innovation, and lay a solid foundation for the promotion of heavy H-beams.
