Product Description
UPSET FORGING PARALLEL THREAD 
SYSTEM 
1. Description 

As an important parallel thread connection technology, the upset forging parallel thread connection technology posses following advantage:
 
1.Wide working range: adaptable for Φ12mm-Φ40mm same diameter, different diameter,
bending, new and old, advance covered up rebar of GB 1499, BS 4449, ASTM A615 or ASTM A706, ACI318,BS 8110, DIN 1045, standard.
2.High strength: 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 JGJ107-2010,JG171-2005.
3.No reduction of the bar cross section area.
4.Allows full ductile elongation of bars.
5.Easy installation, no torque wrench required.
6.One standard coupler for all splicing requirements (Standard/Position).
7.Manufactured under strict quality assurance plan, ISO 9001 and ASME certified.
8.Full traceability of material origin and production batch.
9.Type 2 coupler suitable for seismic areas.
10.Tested under reverse-cyclic conditions.
11.Solves bar congestion problems.
12.No staggering of spliced bars required.

Remarks:
According to Chinese standard GB 1499.2-2007,
For rebar HRB400:Tensile strength≥540Mpa,Yeild strength≥400Mpa;
For rebar HRB500:Tensile strength≥630Mpa,Yeild strength≥500Mpa.
The upset forging parallel thread connection technology can not only be used for the   connection of HRB400 rebar, but also for other rebar, such as HRB500, Gr.60, Gr.75, Gr.80, B500B,B500C, etc. Those of tensile strength is more than 700Mpa and so on.

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. 

Application in Construction Project
China: Beijing capital airport,Hangzhou Bay Crossing Sea Bridge,Jiaozhou Bay Tunnel,Jin mao Tower,Qinshan Nuclear Power Plant,Shanghai Oriental Pearl Tower,Three Gorges Dam,etc.
Qatar: Lusail Expressway,Doha Metro,etc.

Mexcio: Sun&Moon Mountain tunnel,etc.


5.Why choose JBCZ 
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 8110 , ASTM A615 or 
ASTM A706 standard.
3,High efficiency: upset forging and threading one joint only needs 
no more than one minute, and handy operation
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.
