高强钢筋机械连接技术发展高强钢筋和大直径钢筋的大量应用推动了我国钢筋机械连接技术的发展,我国钢筋机械连接技术从上世纪八十年代中后期开始发展和应用。首先是套筒冷挤压连接技术(1987年),其次是锥螺纹连接技术(90年代初期)、镦粗直螺纹连接技术(90年代中期)、滚轧直螺纹连接技术(90年代中后期),后来是剥肋滚轧直螺纹连接技术(1999年)。剥肋滚轧直螺纹连接技术是我国目前应用最为广泛的粗钢筋机械连接技术。该连接技术由中国建筑科学研究院建筑机械化研究分院、廊坊凯博建设机械科技有限公司开发,获
The development of the mechanical connection technology of high strength steel bar and the large number of applications of high strength steel bar and large diameter steel bar have promoted the development of mechanical connection technology of steel bar in China. The mechanical connection technology of steel bar in our country has been developed and applied since the mid and late 1980s. The first was the sleeve cold extrusion connection technology (1987), the second was the taper thread connection technology (early 1990s), the upset straight thread connection technology (mid-90s), the rolling straight thread connection technology (mid and late 90s) , Followed by peel rib rolling straight thread connection technology (1999). Peel rib rolling straight thread connection technology is currently the most widely used in our country crude steel mechanical connection technology. The connection technology by the China Academy of Building Research Building Mechanization Research Branch, Langfang Kaibo Construction Machinery Technology Co., Ltd. developed by
