Rebar couplers   play a crucial role in connecting reinforcing bars and are essential components for strengthening concrete structures. By utilizing rebar couplers, the compressive performance, load-bearing capacity, overall stability, flexibility, and seismic resistance of structures can be significantly enhanced. Types of Rebar Couplers: 1. Fixed Rebar Couplers: Fixed rebar couplers are a common type of coupler made of metal material, typically cylindrical in shape with  an inner diameter that matches the diameter of the rebar. These couplers are easy to install, closely compatible with the rebars, effectively transfer forces, and ensure a stronger and more secure structure. 2. Threaded Rebar Couplers: Threaded rebar couplers are a prevalent high-strength connection method compared to traditional fixed couplers. Usually made of carbon steel, these couplers undergo galvanization treatment to enhance corrosion resistance, providing higher load-bearing capacity and durability. ...

The "JG/T 163-2013 Steel Rebar Mechanical Coupler" specifically stipulates the minimum size parameters for rolling straight threaded rebar couplers, steel column coarse straight thread couplers, and steel straight thread couplers. Any steel rebar straight thread coupler with a size below the minimum size table of the national industry standard JG/T163-2013 for rebar connection is considered a non-standard steel rebar straight thread coupler. Conversely, any steel rebar straight thread coupler meeting or exceeding the requirements of the national industry standard JG/T163-2013 is considered a standard steel rebar straight thread coupler. The qualified standards for  rebar coupler  are as follows: 1. Coupler are made of international grade 45 steel, with special manufacturing processes ensuring high dimensional accuracy and reliable quality. 2. Capable of connecting HRB335 grade and HRB400 grade ribbed steel rebars ranging from Ф16 to Ф40mm. 3. After testing by the National Ce...

The   rebar threading machine   is a non-cutting processing equipment that can improve the surface quality and strength of workpieces, thereby enhancing the effectiveness of the workpieces. This operating process is rapid and energy-saving. In recent years, the usage rate of rebar threading machines has been continuously increasing. This is primarily because the machine can quickly and precisely thread large pitch workpieces, high-strength bolts, trapezoidal bolts, screws, and other items. To operate rebar threading machine skillfully, the must and first is understand its structure and the function of its various components. Regular maintenance is essential for rebar threading machines, including inspections and upkeep of the threading wheels and rib peeling cutters. Before use, the chassis needs to be securely grounded. Maintenance of the oil pump should be carried out in a minimally dusty environment to prevent the entry of sand particles into the machine, thereby reducing w...

Rib peeling roll thread rebar coupler   is a new type of steel bar connection sleeve technology. The principle involves peeling off the longitudinal and transverse ribs at the end of the steel bar to be connected, then rolling them into straight threads, and finally connecting them by using a specially designed straight thread rebar coupler. The advantages of rib peeling roll thread rebar coupler: 1. Excellent mechanical performance and reliable connection safety. By rolling the end of the steel bar to form a reinforced thread, the connection strength is higher than the base material strength, while ensuring that the strength and ductility of the base material are fully utilized. 2. Convenient connection operation can be easily carried out in confined spaces and densely packed steel bar areas, with high construction efficiency. Prefabricated steel bar connection sleeves ensure construction quality, and the efficient processing capacity of on-site rolling thread equipment makes it a...
