“新潮一族” “有山必有路”,有建筑必有钢结构。在钢结构大家庭中,又涌现出“新潮一族”——H型钢。 H型钢因形如英文字母“H”而得此别名,其“学名”为“宽翼缘工字钢”,它问世于70年代欧美等发达国家,广泛用于厂房结构、高层建筑、地下铁道、桥梁、电视塔、飞机库等重要工程。国外生产H型钢有轧制和焊接两种。目前.我国尚不能生产轧制H型钢。我国第一条焊接H型钢生产线,经武钢金属结构厂和冶金部建筑研究总院等单位联合组织攻关会战,于1980年研制成功,现已实现了批量生产。建立焊接H型钢生产线不仅填补了我国生产新型建筑钢结构的一项空白,也为我 “New Wave Family” “There must be a road to the mountains.” There must be a steel structure in the building. In the large steel structure family, “new wave” - ​​H-shaped steel emerged. H-shaped steel is named after the English alphabet “H” and its “scientific name” is “wide-wing flanged I-beam.” It came into being in developed countries such as Europe and America in the 1970s, and it is widely used in factory buildings, high-rise buildings, and underground railways. Bridges, TV towers, hangars and other important projects. Foreign production of H-beam steel rolling and welding two. At present, China cannot produce rolled H-beams yet. The first welded H-beam steel production line in China was jointly organized by the Wuhan Iron and Steel Metal Structure Plant and the Ministry of Metallurgical Construction Research Institute and other units. The system was successfully developed in 1980 and has now achieved mass production. The establishment of a welded H-beam production line not only fills a gap in the production of new-type construction steel structures in China, but also for me.
