Machine specification table :





Upset forging parallel thread rebar coupler matches with automatic machinery process, the size is 12mm-40mm. At the same time, according requirements of customers, it can be customized. If you need rebar couplers, please click on the following picture enter into the rebar coupler understand and choose:

JB-2014 Automatic Upset Forging Parallel Thread Machine with different size of rebar couplers

The strength of rebar coupler can be designed according the requirements of customers, or the standard value and different parameter provided by customers, rebar coupler can satisfy:

1. Upset forging parallel thread connection is 100% higher than steel bar raw material, reinforcement connection belongs to the world’s highest standard requirements.

2. Satisfy: American ACI-318, British BS4449, France and other world’s highest quality inspection.


The connection of rebar couplers With JB-2014 Automatic Upset Forging Parallel Thread Machine

After finishing rebar connection, the tensile strength is 700-1050MPA, yield strength is 500-800MPA.  

 


Test result is 100% higher than steel bar raw material standard, tensile test is bar break, and the joint of rebar coupler is well.

JBCZ upset forging parallel thread connection is 100% higher than steel bar material strength , rebar connection belongs to the world’s highest standard requirements, satisfy: American ACI-318, British BS4449, France and other world’s highest quality inspection.

After finishing rebar connection, the tensile strength is 700-1050MPA, yield strength is 500-800MPA. 



There are many types of connection , satisfy each connection request on job site: 

Standard type, this connection type is suitable for 80% projects.

II.Reducing rebar coupler connection, suitable for the change between story , for example , the basement adopt 32mm rebar , the story use 25mm rebar , it need reducing coupler in this situation , 

one end connect 32mm , another end connect 25mm , satisfy rebar connection in different sizes.

III.Adding length coupler connection , this type of connection suitable for the situation that two reinforcing bars can’t be rotated , such as the rebar cage connection at job site , 

both of the rebars can’t be rotated, then this type of connection is the most suitable one.

First step , screw the full coupler onto the first bar

Second step , screw back the coupler onto the second bar 

Third step , finish the connection

Ⅳ.Left and right hand coupler connection , this type is suitable for the project that two rebars or one rebar can’t be rotated , the advantage is only need to rotate the coupler can finish the connection of two rebars. 

One end of rebar thread is right hand , the other end of rebar thread is left hand , the rebar thread match with coupler, tighten two rebars while rotate the coupler , the coupler size : 12mm to 40mm rebar connection range.

Ⅴ.Adding length with nut connection , it is the same principle as adding length coupler connection , suitable for connecting two reinforcing bars which can’t be rotated, use the nut to fix the coupler make it can’t move up and down.

Ⅵ.Terminal coupler connection , this type is suitable for the embed project such as embedded column, wall embedded, all need this type , during the embedded , in order to prevent the concrete poured, each coupler will with one plastic cover to protect the thread of coupler . Product size satisfy : 12mm to 40mm rebar connection range.
