  Cost Effectiveness The conventional method of connecting reinforcement bars with lap joints in reinforced concrete need not be always appropriate. Advantages of simplicity and economy in lap splicing is limited to smaller diameter bars, mechanical couplers offer the solution for splicing when large diameter bars are involved like 20，25，32 and 40mm Diameter where huge cost saving can be done. Structural Reliability Coupler spliced perform like continuous reinforcement. That develops full tensile strength mechanically, independent of concrete. Coupler splices are excellent for severe condition like earthquake, typhoon, especially suitable for condition that demands higher ductility of building structure. Designers Friendly Rebar-join coupler reduces rebar congestion and improves concrete flow & consolidation. It offers greater flexibility in design options. The simplicity in detailing of reinforcement, particularly in reinforcement congestion zones minimizes the reinforcement f...

 How to distinguish the positive and negative wire coupler s of straight threaded couplers, how to distinguish the positive and negative wire couplers of straight threaded couplers? There are two ways to distinguish the positive wire and the reverse wire in the conventional straight thread connection coupler , as follows. You can hold the threaded connection coupler with your right hand. If the helix angle of the thread is in the direction of the thumb, it is a positive thread; if it is the opposite, it is a reverse thread. If you hold it in your hand and rotate clockwise, it can be screwed in, and if it is rotated counterclockwise, it is a positive wire; It can also be seen with the naked eye that each coupler of the coupler has a corresponding steel stamp.

Straight thread sleeve   is used for mechanical joints to transmit axial tension or pressure of steel bars. Straight thread sleeve is divided into direct rolled straight thread sleeve, stripped rib rolled straight thread sleeve and upsetting straight thread sleeve. Material requirements for straight thread sleeve: 1. Straight thread sleeve should be made of round steel or seamless steel pipe with grade 45, and its mechanical properties and chemical composition should meet the requirements of GB/T 699, GB/T 8162 regulations. Other steel materials can also be used, and their mechanical properties should meet the requirements of the corresponding national or industry standards and be confirmed by type inspection. 2.  For sleeves that need to be welded with steel such as structural medium steel, the material should meet the weldability requirements.
