锥螺纹钢筋接头(图1)属于机械式钢筋接头,即在钢筋加工厂或施工现场,用专用套丝机,把钢筋的连接端加工成锥螺纹,通过锥螺纹连接套,用专用扭力扳手按规定的扭矩值,把两根钢筋连接在一起的新技术。国外已将该技术广泛地应用于对抗震、防爆要求很高的建筑物与构筑物,如大型高层公共建筑、火电站、核反应堆、地下铁、隧 Taper-threaded steel bar joints (figure 1) belong to the mechanical steel bar joints, that is, in the steel bar processing plant or construction site, with a special pipe threader, the steel bar’s connection end is processed into taper thread, through the tapered thread connection sleeve, and pressed with a special torque wrench. The specified torque value, a new technology that connects two reinforcing bars together. The technology has been widely used in foreign countries for buildings and structures that are highly resistant to earthquakes and explosions, such as large high-rise public buildings, thermal power plants, nuclear reactors, subways, and tunnels.
