Steel bar connecting sleeve and steel bar connecting method
The invention provides a reinforcing steel bar connecting sleeve and a reinforcing steel bar connecting method.The reinforcing steel bar connecting sleeve comprises a sleeve body, a first internal thread extending in the axial direction of the sleeve body is arranged in the sleeve body, and the two ends of the sleeve body are each provided with a section of the first internal thread so that the first internal thread can be connected with two reinforcing steel bars; and the small diameter of each section of first internal thread is gradually reduced from the end part of the sleeve body to the middle part of the sleeve body to form a conical thread section. The threaded sleeve and the extrusion sleeve are integrated, the conical internal thread structure is arranged in the sleeve body, and the conical internal thread can gradually weaken the section of a reinforcing steel bar from outside to inside so as to adapt to the stress change of the reinforcing steel bar, so that the stress consistency of the reinforcing steel bar is ensured, and the connecting strength of the reinforcing steel bar is improved; therefore, the connecting structure which is high in tolerance, high in quality and low in cost and is used for reinforcing steel bar extension can be provided.
本申请提供了一种钢筋连接套筒及钢筋连接方法，钢筋连接套筒包括套筒本体，套筒本体内设有沿其轴向沿延伸的第一内螺纹，第所述第一内螺纹在套筒本体的两端各设一段以分别用于连接两根钢筋，每段第一内螺纹的小径从套筒本体的端部朝向套筒本体的中部逐渐减小以形成锥形螺纹段。本申请通过将螺纹套筒与挤压套筒集成于一体，在套筒本体内部设置锥形内螺纹结构，锥形内螺纹能够实现对钢筋截面的削弱由外到内逐渐增大，以与钢筋受力变化相适应，确保钢筋受力的一致性，提高钢筋连接强度，从而能够提供一种钢筋接长的高容差、高质量、低成本的连接结构。
