随着建筑事业的发展,传统的钢筋连接工艺已远远不能适应现场钢筋混凝土工程大直径钢筋的连接要求。近年来虽然钢筋连接工艺有所改进,质量有所提高,如电渣压力焊等对提高焊接质量、加快施焊周期、节约钢材有一定效果,但耗电量较大,设备投资也高,安全施工又不易保证,难以大量推广应用。为此河北省兴隆县机械厂、北京市第六建筑工程公司、北京市建筑设计院、北京市建筑工程总公司科技处四个单位于1984年组成研制小组进行气压焊工艺的研究。通过半年多的试验研究,于1984年将气压焊工艺
With the development of the construction industry, the traditional steel bar connection technology has not been able to meet the requirements for the connection of large-diameter steel bars for on-site reinforced concrete works. In recent years, although the steel connection technology has been improved and the quality has been improved, such as electroslag pressure welding has a certain effect on improving the welding quality, speeding up the welding cycle, and saving steel materials, but it has a large power consumption, high investment in equipment, and safety. Construction is not easy to guarantee, it is difficult to promote a large number of applications. To this end, Hebei Province Xinglong County Machinery Factory, Beijing No. 6 Construction Engineering Company, Beijing Architectural Design Institute, Beijing Construction Engineering Corporation Science and Technology Department formed a research group in 1984 to conduct pressure welding process research. Through more than six months of experimental research, the pressure welding process will be in 1984
