A Comprehensive Guide to Selecting Rebar Coupler

图片
Rebar couplers   are common and essential building material accessories that are widely used in construction structures. This article will delve into a comprehensive guide to selecting rebar couplers to help you better understand and choose the right rebar couplers for your engineering projects. Guide to Selecting Rebar Couplers 1. Material Selection: The material of rebar couplers directly affects their load-bearing capacity and durability. In general, rebar couplers made of carbon steel that have good strength and corrosion resistance, making them a common choice. If used in corrosive environments, galvanized rebar couplers can be selected to enhance their corrosion resistance. 2. Size matching: It is very important to choose the right size of rebar coupler, which should match the diameter of the rebar to ensure that the rebar can be tightly installed in it. Too big or too small size will affect the stability and force transmission effect of the coupler. 3. Quality Certification:...

Types of Rebar Couplers for Concrete Structure

图片
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. ...

JG/T 163-2013 Steel Rebar Mechanical Coupler National Standard

图片
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 Processing of Rebar Threading Machine is a Non-cutting Processing

图片
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...

Advantages of Rib Peeling Roll Thread Rebar Coupler

图片
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...

Structure & Characteristics of One Touch Rebar Coupler

图片
One touch coupler   is a node piece coupled to the groove of the rebar node with excellent tensile strength. Here we will delve into the structure & characteristics of one touch rebar coupler. The barrel of one touch coupler is made al forged round bar, not pipe, so the structure is compact and excelent rigidity is maintained, Inside, it consists of 1st angle and 2nd angle, and when the reinforcing bars are inserted, it increases the holding force of Wedge, The wedge of one touch coupler is a special tooth shape that holds the rebars of all shapes, such as Bamboo and Fishbone, The spring of one touch coupler increases the clamping power ot the wedge with strong elasticity. The sockets of one touch coupler are screwed into the upper and lower barrels and tighlened together, The 0-ring of one touch coupler is inserted in the guide groove to prevent the wedge from falling out of the product due to shocks during transportation and handling, thus enhancing the stability of the produ...
