Product Description

BS4449 Standard Rebar Parallel Screw Thread Epoxy Sleeve Coupler


1. Description of machinery

The upset forging parallel thread machine contains : 
one rebar threading machine(GZL-45) 
one oil pump 
one upset forging machine(GD-150) 
they work together with couplers for the connection of rebar whose diameter is between 12mm and 40mm . 


2. The parameter of standard rebar couplers:
Steel bar Diameter(MM) Out Dia.of Coupler(MM) Inner Dia.of Coupler(MM) Length of Coupler(MM) Size of Thread(MM) 
12 20 11.9 30 M14*2 
14 22 13.9 34 M16*2 
16 26 17.4 40 M20*2.5 
18 29 19.4 44 M22*2.5 
20 32 20.9 48 M24*3 
22 36 23.9 52 M27*3 
25 40 26.3 60 M30*3.5 
28 44.5 29.3 66 M33*3.5 
32 50 31.8 72 M36*4.0 
36 56 34.8 80 M39*4.0 
40 62 40.3 90 M45*4.0 


3. Working principle 
First, we use GD-150 to forging the end of rebar. 
Second, we use the GZL-45 to threading the end of rebar. 
Third, we use the coupler to link the two ends of rebar. 


4. What makes us successful 
A. Shorten your engineering period -- the two rebars can be connected within 35 seconds; 
B. Catch the highest quality -- 100% broken rebars, no safty worrying, can past any safty quality
 test; 
C. Save rebars -- give up weld and colligation rather than our connecting methods, can save many rebars materials. 



5.Why choose JBCZ rebar couplers and machinery
1), High strength: the strength reach Grade I , stronger than the reinforcement bar and guarantees bar break under
tensile stress (tensile strength of connection point =1.1 times of connected bar).
It can satisfy the requirements stipulated in the Chinese standard 
JGJ107-2003,JG171-2005.
2 ),Wide working range: adaptable for Φ12mm-Φ50mm same diameter, different diameter, bending, new and old,
advance covered up rebar of GB 1499 , BS 4449 , ASTM A615 or
 ASTM A706 standard.
3),High efficiency: upset forging and threading one joint only needs no more than one minute, and handy operatin  and quick link.
4),Environmental protection and economy profit: no
environment pollution, can work all day, not affected by
weather, economize energy source and bar material.
