The   upsetting forged rebar coupler   is created by thickening the ends of steel bars, which are then threaded to form a steel connection that interlocks with the matching threads of the coupler. The process involves the use of upset forging equipment to increase the cross-sectional area of the rebar end, after which threads are cut or rolled. An important feature of this connection is that the minor diameter of the threads must be equal to or greater than the diameter of the base material, ensuring that the coupling joint matches the strength of the parent material. On the other hand, the  straight-threaded coupler  connection is engineered by directly threading the ends of the rebar, either through rolling or rib peeling before threading. This technique results in a connection where the threads of the rebar and the coupler intertwine, eliminating the necessity for additional thickening at the rebar ends. Both the upsetting forged rebar coupler and straight-threade...

There are three common connection methods of   reinforcing steel bar connection sleeve : The one-way adjustable reinforcing steel bar connection sleeve means that the lower reinforcing steel bar and the connection sleeve, and the adjustable connector and the upper reinforcing steel bar are respectively tightened to the specified torque value with a torque wrench, and then the lock nut and the connection sleeve are tightened. The two-way adjustable reinforcing steel bar sleeve means that the lower reinforcing steel bar and the adjustable connector, and the adjustable connector and the upper reinforcing steel bar are respectively tightened to the specified torque value with a torque wrench, and keep the number of exposed threads of the adjustable connector equal, and then clamp the upper and lower adjustable connectors respectively, and tighten the connection sleeve. The same-diameter or different-diameter common reinforcing steel bar connection sleeve means that the lower reinforcin...

Rebar couplers   primarily made from 45# carbon structural steel, are essential components in ensuring the strength and integrity of concrete structures. However, one of the primary concerns with rebar couplers is their tendency to rust when exposed to moisture. Understanding why rebar couplers rust and how to mitigate this risk is vital for any construction project. Key Reasons for Rusting of Rebar Couplers 1. Cutting Fluid Quality during Reprocessing: During the machining process of rebar couplers, a cutting fluid is employed for threading operations. This cutting fluid is typically a water-soluble oil, which possesses some rust prevention and removal qualities. However, if the cutting fluid is of poor quality or has an inadequate concentration, the rebar couplers may become vulnerable to rust, making their storage problematic. 2. Packaging Material Integrity: The packaging for rebar couplers usually consists of woven bags with a membrane liner. If the quality of these packaging ...

The   rebar cold extrusion machine   achieves the purpose of rebar connection by generating mechanical occlusion through the extrusion of the connecting sleeve. It is used to connect grade II and III threaded rebars with a diameter of 40mm and below. It is used for rebars with poor welding performance, construction sites with insufficient power capacity, and projects with tight construction period requirements. The rebar cold extrusion machine is more superior. Its characteristics are as follows: 1. The connection quality is stable, reliable and consistent, ensuring that the connection part is as strong as the base metal. 2. Compared with the ordinary welding process, the efficiency can be improved by more than three times. 3. The operation is simple, and the operator can go on duty only after simple training or reading the manual. 4. The use of the rebar cold extrusion machine is not limited by the environment and weather, there is no fire danger, no arc light irritation and ...
