(6)螺纹钢筋套管连接:这种机械连接由套管及两个锁紧螺母构成,套管内壁攻有与螺纹钢筋相匹配的螺纹。这种连接的特点是可以对接两根均不能转动或其中一根是不能转动的钢筋,适用范围为Φ25～Φ51螺纹变形钢筋。这种连接方式对钢筋对接端面的加工无特殊要求,剪截或用砂轮切断均可。施工前,端头应经过检查,端面必须垂直于钢筋轴线,偏差不得大于1.5°。螺纹套管锁紧螺母应采用扭矩搬手紧
(6) Threaded rebar connection: This mechanical connection consists of a sleeve and two lock nuts. The inner wall of the sleeve is tapped to match the thread rebar. This connection is characterized by the ability to butt two steel bars that cannot be turned or one of which cannot be turned. The applicable range is Φ25 to Φ51 thread-reinforcing bars. This connection method has no special requirements on the processing of the butt end face of the steel bar, and can be cut or cut with a grinding wheel. Before construction, the end should be inspected and the end face must be perpendicular to the axis of the bar. The deviation should not exceed 1.5°. Threaded sleeve lock nut should be tightened with torque
