The basic parameters of rebar couplers are designed in accordance with the strength requirements of HRB500 steel bars, and also can be applied to HRB335 and HRB400 rebars. 3. The performance indexes of the rebar coupler have been tested by the "National Construction Engineering Quality Supervision and Inspection Center", and all of them meet the requirements of the "I" class joint in JGJ107-2016 Technical Regulations on Mechanical Connection of Rebar. 4. The specifications match the diameter of the connected steel bar, being divided into ten regular specifications: φ14mm, φ16mm, φ18mm, φ20mm, φ22mm, φ25mm, φ28mm, φ32mm, φ36mm, φ40mm, as well as special specifications: φ10mm, φ50mm. 5. Three series (standard rebar coupler, lef...

The parallel threaded rebar coupler connection is that a part of the longitudinal and transverse bars at the end of the steel bar is cut and peeled by a wire roller and it is rolled directly into ordinary parallel threads, then the special  parallel thread rebar coupler  is applied to form a steel bar connection. The technology of rib stripping rolling parallel thread connection has reached the advanced international level. Rib-stripped parallel threaded coupler connection technology is favored by the majority of construction units and owners due to its advantages of convenient construction, energy saving and consumption reduction, improved production efficiency, and stable and reliable connection quality. It is a new product of parallel thread connection technology. When using the parallel steel thread coupler, pay attention to installation precautions to avoid unnecessary technical problems that may affect the quality. 1. Steel bars in place: Move the steel bars that have p...

Advantages of   whole grouting sleeve   compared to half grouting sleeves: 1. Under the condition that all performances can be met, the grouting sleeve pressed by special equipment and special process is lower in cost and easy to use compared with the grouting sleeve processed from bar material and the sleeve cast by ductile iron. (2) When prefabricating components in the factory, the steel bar can be directly inserted into the sleeve, which saves the some steps if use half grouting sleeve, like threading and tightening the half grouting sleeve. The installation is fast and convenient, and the positioning accuracy can meet the standard requirements of use; (3) Both ends are connected to the steel bar through high-strength grouting material, so the connection quality at both ends of the joint can be effectively guaranteed.

Changsha DLADTO Rebar Splice Co., Ltd   is a professional rebar coupler producer, we have been in this field for a long time with customers for all over the world. We are like to share knowledge and information of product with customer, today we are do a brief introduction of   threaded rebar coupler . 1. Couplers are made of No. 45 high-quality carbon structural steel, it has advanced technology, high dimensional accuracy and reliable connection quality. 2. The basic parameters of various specification couplers are designed according to the strength requirements of HRB400 steel bars, also it applicable to HRB335 and HRB400 steel plates. 3. The coupler performance indicators have been tested by the "National Construction Engineering Quality Supervision and Inspection Center", and meets the requirements of "I" grade joints in JG/T 163-2013. 4. The specification of couplers are matched with the diameter of the steel bars that to be connected, they are divided into ten...

Rebar couplers, also known as mechanical splices, join the lengths of two reinforcing bars together. The rebar coupler is roughly divided into  cold extrusion rebar coupler , straight thread rebar coupler, left and right-hand rebar coupler, welded rebar coupler, coupler with different inner diameters, etc. The application of mechanical splice has been very useful in some construction sites. But why are some prices high and others low?    The price of the rebar coupler is related to: 1. The price of the rebar coupler is related to its specification. Typically, there are 18, 20, 22, 25, 28, 32, and other specifications.     2. The price is related to the steel market. The ups and downs of rebar couplers follow the steel industry. 3. Th price is related to the quality of the  rebar coupler . The better the processing quality and the more the detection process is, the cost will be high and the price will be high. 4. The price is related to manufacturers. ...

Different Usage 1.  Threaded rebar coupler  is to peel off part of the longitudinal ribs and transverse ribs at the ends of the steel bars to be connected by cutting with a thread rolling machine, and then roll them into ordinary straight threads directly, and connect them with a special threaded sleeve. The technology is efficient, convenient and fast. 2.  Cold extrusion rebar coupler  connection is to put two bars into the rebar coupler, then use a cold extruder to extrude the connection sleeve radially, so that the coupler is cold plastically deformed and the steel bars are tightened. This connection method is used for grade II and grade III steel bars with a diameter of 16 to 40 mm, which are divided into radial extrusion and axial extrusion. Different Technology 1. Threaded rebar coupler relies on two pipe wrenches to tighten the steel bar and the casing to connect the two steel bars. 2. Cold extrusion rebar coupler is to squeeze the casing through the extrusion...

Steel Bar mechanical splices include various types: parallel threaded rebar coupler,   upsetting forged rebar coupler , cold extrusion rebar coupler, grouting rebar coupler, split-type rebar coupler and so on. Parallel threaded rebar coupler can be divided into rib stripped parallel rebar coupler and parallel threaded coupler for splicing rebars with threads roll on to rebar end. Regardless of the type of coupler, the specification is named after the specification of the steel bar to which it is connected. For example, the coupler connecting 25mm steel bar is called the 25mm coupler.  At present, the specifications of rebar couplers are 12, 14, 16, 18, 20, 22, 25, 25, 32, 36, 40, 50, and there are also left and right hand thread rebar coupler and coupler with different inner diameter. For example, 25/28 left and right hand thread rebar coupler; 28/22 different inner diameter  rebar coupler .  In the process of using mechanical splice, the specifications and models o...
