镦粗直螺纹钢筋接头和滚焊机在桥梁施工中的应用

Application of the Upsetting Straight Twisted Steel Jjoints and Roll Steel Welders on the Bridge Construction

直螺纹纲筋接头是对钢筋端部冷镦扩粗、切削螺纹,再用连接套筒对接。工程实践表明,这种接头具有强度高、质量稳定、施工方便、连接速度快、应用广泛等优点。结合工程实际,介绍直螺纹钢筋接头的特点、施工工艺及应用。

Upsetting straight twisted steel joints is to expand the crude cold heading,thread cutting,and then connecting sleeve butt.Engineering practice shows that this joint has a joint with high strength,stable quality,convenient construction,quick connection speed,wide range of applications and so on.According to practice of a project,the characteristics of straight thread joint,construction technology and applications have been introduced.
