Quick Detail:


Description of products:

To solve technical problem which will happen in construction structure, transverse beam and vertical column will have some space and some of parts will not in same position,and both side can not rotate and move,in this situation,JBCZ designed this adjustable rebar coupler.

JBCZ is one company which established in 1987, producing,researching and developing rebar connection coupler and machine professionally.JBCZ got the first patent approval from Chinese government in 1997.And JBCZ was the first enterprise who drafted the standard of Chinese steel bar connection technology.Also JBCZ is the one who first initiated Chinese rebar coupler technology.

The advantage of column and beam connection


1.Easy to assemble, during the column and beam 

assembling, easy to operate ,only use coupler to 

connect and lock nut can complete the whole process. 

Butt two rebars , only need 35 to 55 seconds.

2.Reduce the support and hoisting at site, also reduce 

the time of installation , only need simple butt joint , at 

least two person can complete the whole process

3.Reduce the fail connection because of some faults, 

shorting of rebars which causes the distance between 

two rebars at site. Compensate the adjustable 

connection according to the real  length of rebars at  

site can be applied here , to reflect the connection 

flexibility.

4.The repairability , after the connection , if 

extraordinary circumstances happen , it can be 

disassemble and re-installation, while not affect the 

whole construction.

5.The connection performance and quality , 

thestrength is equal or higher than rebar strength.


Brief introduction:

First term:

Second Item:pictures of actual application projects:

1.The application of traffic project at site

2.The pictures of the frame structure connection at site

3.The connection of bottom structure and main structure at site

4.The connection of column type main structure at site


Third term: Installation demonstrate

1. Process thread on the end of two rebars, prepare JBCZ adjustable coupler

2. Rotate adjustable coupler A to rebar in horizontal connection beam body

3.Rotate adjustable coupler B to rebar in column.

4.Butt joint beam and column, use female screw to adjust the connection if the rebar length is not long enough.
