Why Rebar Coupler at the place of conventional lapping system:Surya Engineering
Why Rebar Coupler at the place of conventional lapping system:
Product Reliability :
The conventional old method of connecting reinforcement bars with lap joints continuity in reinforced concrete need not be always appropriate. Advantages of simplicity and economy in lap splicing is limited to smaller diameter bars, mechanical couplers offer the solution for splicing when large diameter bars are involved like 23 ,25 and 32 mm Diameter where huge cost saving can be done.
Why Rebar Coupler :
Technically Good: Spliced rebar performs like continuous reinforcement. Splicing develops strength mechanically, independent of concrete. Therefore provides ductility in RCC structures independent of condition of concrete. Proven cyclic performence of spliced rebar offers strength during man-made, seismic or other natural events.
Designer Friendly :

Designer Friendly :
Ecofix coupler reduces rebar congestion and improves concrete flow & consolidation. It offers greater flexibility in design options. The simplicity in detailing of reinforcement, particularly in reinforcement congestion zones minimizes the reinforcement fixing errors, detailing and fixing of seismic reinforcement becomes effortless. Workability with higher steel-to-concrete ratio allows optimum sizing of RCC structural column.
Contractor's Choice :
Ecofix coupler offers quality, cost and time saving. Fixing couplers requires no special skills or equipments. Simple mechanical ways in adopting mechanical splicing compared to lapping, accelerates construction schedules for optimum cost and efficiency.
Handling the rebar in convenient sizes saves on valuable crane time. It is economical to use couplers for higher diameter rebar as it saves on considerable weight and rebar wastage.
Easy manufacturing :
Rebar coupler can be made easily on CNC Machine,whwre lost of cost saving can be done for l;arge diameter like 32 and 25mm Rebar tMt bars.
Material Specification:
EN 8 D Steel Grade is used to manufacture Rebar coupler with carbon content of 0.40 to 0.45 %.
C 454 Grade also can be used to sustain 650 MPA.

Rebar couplers can be used in construction by Roll thread Method and By Cold Forging system Method.
Roll Thread Method:
In Roll thread system ,Single thread machine Required to make threading on Rebar directly by pressing TMT bars by using Thread Rolllers.This metthod is also called as Rib Peeling threading Method.
Three Thread Rollers are used in Machine to make roll thread on rebar.
This kind of system Can be used for small buildings like upto 20 storey tower .
32 mm and 25 mm TMT bar can be threaded by same roller beacuase of same pitch i.e 3.5 mm.
COLD Forging Sytem of Rebar coupler:
In cold forging type of system Forging machine is required to forge TMT bar i.e to to increase Outer diameter to Maintain cross section area as of parent during threading operation.
AS per ACI 318 and IS 1786 standard tensile strength of Rebar should of 1.25 times of Capcity.
Suppose we are using FE 500,then tensile strenth in pull up test shoud be 625 MPA or More,then only we can say coupler is passed.i.e Bar break
Normally for small diameter bars like 16 mm,20 mm,25mm,rebar Roll threads system can be used because there is no huge difference in cross section area,but 32 mm and above its recomenede to use COLD Forging system for better strength.
