Lenton standard Construction Material Cold Forging Screwless Splicing Couplers:
1.Description of Cold Extrusion Press System Machine:
This system contains YJ650 machine, YJ800 machine and coupler. The products meets the requirement of JGJ108-96.
1). One full set of YJ650: can process rebar whose diameter is from 16mm to 32mm.
2). One full set of YJ800: can process rebar whose diameter is from 32mm to 40mm.
3). One full set of YJ650 and PRESSURE EQUIPMENT of YJ800 can process 16mm-40mm.
2.Working principle of Cold Extrusion Press Machine:
It can link the rebar with sidewise extrusion by the cold extrusion press machine, make the coupler plastic deformation then occlude tightly with the steel in order to link the rebar.
3. Advantages Cold Press Rebar Couplers:
It belongs to Grade 2 connection
(1)The tensile strength of rebar splicing is very strong, it can meet requirement of standard at home and abroad such as: China Standard(JGJ107), America Standard(UBC1997), British Standard(BSB110), French Standard(NF25-20-1), German Standard(DIN1045), ISO/WD15835(draft);
(2)Handy operation, no need skilled operator;
(3)Small need of impetus, no affected by the electric power supply in the site;
(4)Environmental protection, no need operation with open flames, no affected by the weather;
4.Parameter of cold press no thread rebar couplers:
of coupler (MM)
|Length of |
TEST: 100% BAR BREAK
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.
5.Description of JBCZ:
JBCZ cold forged splicing is suited to projects which require high volumes of couplers. The ends of the bars to be joined are cut square and enlarged by cold forging to increase their core diameter and so ensure that the joint is stronger than the bar. The couplers are usually supplied attached to the reinforcing bar.
6.Applications of JBCZ Rebar Couplers and Machines:
Hangzhou Bay Crossing Sea Bridge, Jiangyin Yangzi River Bridge, Jiangsu Runyang Bridge
Commercial Building Project
Burj Khalifa Tower, Oriental Pearl tower, Saraya Tower, Jinmao Tower
Beijing Capital Airport, Qinshan Nuclear Power Plant, Gazi-Barotha Hydropower Station In Pakistan, North Jeddah Water Pump Station, Dubai Metro, Suzhou Gymnasium
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
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 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.
8.Competitive Advantages of JBCZ rebar couplers and machinery:
1).Quick and easy installation
2).Well meet seismic requirement
3).Meet slip test requirement
4).Manufactured under strict quality assurance plan ISO 9001 and Technical Approval TAC-133
