中國是最早用铁作为承重結構的國家.远在秦始皇時(公元前246至210年)即已用铁作成簡單的桥墩;至遲在漢明帝時(公元465-472年)即可制作铁鏈桥。在公元三世紀至六世紀,与西方國家來往很多,交通時多用铁鏈桥跨越巨大河谷.明、清兩代所建的铁鏈桥很多,其中最有名的有盤江桥、元江桥及瀘定大波河桥等,周武氏十一年(公元694年)建有鑄铁的“天樞”一座;宋代有三座铁塔的建築.中國古代由於封建的統治,冶金工業不發達,因此也就限制了鋼铁結構的發展。在十九世紀外國資本主文侵入以後,中國開始使用近代的鋼鐵結構;其時建造桥梁較多,較大的有鄭州附近的黃河析、济南附近的黃河桥、蚌埠的淮河桥等.高層建築有1930-1940年在上海建造的四行儲蓄会新屋、百老匯大樓等;其他結構有北京东直門水塔等.中國最早的金屬結構廠为1894年所建的山海關桥梁廠.这一時期,中國工程師也建造了一些創造性的建築,如錢塘江大桥、柳江林、瀾滄江桥及怒江懸索桥等.但因受到社会制度的限制,人民的創造能力也就不能充分發揮。解放以後,巾國鋼铁結構得到大規模的發展。在最近六年中,我們恢復了与新建了大量的工廠与桥梁,較大的工廠有鞍鋼的大型、薄鈑、無縫三大廠房,第一汽車廠廠房等.桥梁方面已建成蘭新路的黃河大桥、漢水公路桥、漢水铁路桥等;現在正建造包蘭路的黃河大桥、湘江大林,並以最先進的技術建造規模宏大的武漢長江大桥.新建的及擴建的較大金屬結構廠有鞍山的金屬結構廠,山海關、沈陽及丰台三个桥梁廠,華北及西北金屬結構廠等.在今後的社全主文建設中,中國鋼铁結構事業將会得到更大的發展。 China was the earliest country to use iron as its load-bearing structure, a simple bridge made of iron as far as the Qin Shi Huang (246-210 BC), and a chain of iron chains (465-72 AD) at the latest bridge. During the 3rd and 6th centuries AD, there were many contacts with western countries, and most of the traffic was crossing the huge valley with a chain bridge.The chain bridges built by the Ming and Qing dynasties are many, of which the most famous ones are the Panjiang Bridge, Yuanjiang Bridge and Lu Dingpu River Bridge and so on, Zhouwu Shi eleven years (AD 694) built cast iron “Tianshu ” one; the Song Dynasty has three iron tower architecture.China in ancient times due to the feudal rule, the metallurgical industry is underdeveloped, therefore It also limits the development of steel structure. After the invasion of foreign capital in the 19th century, China began to use the modern steel structure; at that time, more bridges were built, including the Yellow River near Zhengzhou, the Yellow River Bridge near Jinan and the Huaihe Bridge in Bengbu. 1930-1940 built in Shanghai, four rows of savings will be new homes, Broadway Building, etc .; other structures such as Beijing Dongzhimen water tower, etc. China’s earliest metal structure plant was built in 1894 Shanhaiguan Bridge Factory. During this period, Chinese engineers also built Some creative buildings such as the Qiantang River Bridge, Liujiang River, the Lancang River Bridge and the Nu River Suspension Bridge etc. However, due to the restriction of the social system, people’s creativity can not be fully exploited. After liberation, the steel structure of the country has been greatly expanded. In the recent six years, we have resumed and built a large number of factories and bridges, the larger factories include Ansteel’s large-scale, thin-sheet and seamless three plants, the first automobile factory building, etc. The bridge has been completed and Lanxin Road The Yellow River Bridge, the Han River Highway Bridge, Han River Railway Bridge, etc .; is now building the Baolulan the Yellow River Bridge, Xiangjiang River Dalin, and the most advanced technology to build large-scale Wuhan Yangtze River Bridge. The new and expanded larger metals The structural plants include Anshan’s Metal Structure Plant, Shanhaiguan, Shenyang and Fengtai Bridge Plant, North China and Northwest Metal Structure Plant, etc. In the future construction of the society’s main text, China’s steel structure business will be further developed.
