Adjustable Rebar Coupler
JBCZ is a professional manufacturer of upset forging parallel thread splice coupler and rebar threading machine.
*Rebar connection range: from 12mm to 40mm, equal to #4 to #12 British rebar size.
- Overview

- 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.
- 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
- 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.
- The repairability , after the connection , if extraordinary circumstances happen , it can be disassemble and re-installation, while not affect the whole construction.
- The connection performance and quality , thestrength is equal or higher than rebar strength.
Features:
It is suitable for the connection that two reinforcing bars can’t be rotated , butt joint the rebar cage.
In many projects , the most common columns need large and dense rebar cages. During the rebar cage manufacturing , it is a common problem how to butt joint two rebar cage , adding length thread connection can help you connect fast and effectively with good quality guarantee.
Is parallel thread splicing system which is designed for Ø12 to Ø40mm（ASTM #4 to #8）rebar conneciton. Designed and produced in compliance with Eurocode 2, BS 8110, DIN 1045, ACI 318, IBC, AASHTO, ASME Sec III Div 2

Advantages:
Installation guide
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.
Application:
during the construction , the connection can be applied in basement, ground, beam and column. In order to help you better understand the application in various construction , we make below sketch map , please kindly find below:
