WHY REBAR COUPLERS ?

For many years, the use of mechanical couplers to join reinforcing bars has been considered a means of reducing the need for long bars. Engineers and contractors now recognise the benefits of using JB Rebar Couplers Reinforcement Couplers to accelerate construction speed, increase productivity, and simplify structural design details.

JB Rebar Couplers - are designed to join the reinforcement bars and perform like continuous reinforcement, develops strength mechanically, independent of concrete, provide ductility in RCC Structures and offer strength during man-made, seismic or other natural events.

Pipe Roofing System is a support system used in loose ground conditions in conventional and mechanized tunneling. It is used to enhance ground properties to stabilize and reduce risk in tunnel works. It is a method of supporting tunnel by driving pipes ahead of excavation. It is also used in developing the portal sections.

JB Rock Bolts is a long anchor bolts, For stabilizing rock excavations, which may be used in tunnels or rock cuts. It transfers load from the unstable exterior to the confined (and much stronger) interior of the rock mass. JB Engineers are among the largest manufacturers, suppliers and exporters of all types of Rock Bolts in India.

JB Engineers Offers Self Drilling Anchors in variants of R25, R32, R38, R51 and T76 and their accessories including the Anchor Nut, Anchor Plate, Anchor Couplers and Drilling bits.

JB Rebar Couplers - reduce rebar congestion, improve concrete flow & Consolidations, minimize the reinforcement fixing errors, increases production rates, because of the reduced installation time & simpler quality controls requirements, cost saving up to 25% can be achieved in any civil Construction project.

Types of JB Rebar Couplers

JB Rebar Coupler offers a beneficial method for concrete constructions. With these rebar couplers , you will speed up your construction, lower the risks of damaged concrete, increase productivity and ensure a simple yet resistant design.

Choose from a series of Reinforcing Rebar Couplers depending on your project's needs:
JB-19 PARALLEL THREAD RE-BAR COUPLERS

This type of coupler is specifically created for the vast majority of processes of joining reinforcing bar coupler. The rebar ends are cut square, and each bar has a tapered thread that fits perfectly into the threaded rebar coupler. With a calibrated torque wrench you can tighten the sleeve to the thread rebar coupler end for a quick and resistant fix.

It is recommended for restricted spaces that require a minimised loss of cover. It is available in diameter sizes between 8mm and 50 mm.

JB-9 REBAR COUPLERS - BAR LOCK

Bar-Lock Coupler System provides a simple, quick, cost effective method for splicing rebar in tension and/or compression applications. Bar-Lock couplers may be used with plain or deformed bars in sizes 8 mm to 50mm. Bar Lock couplers utilize lock-shear bolts and special grip rails to mechanically splice with the rebar. The serrated grip rails cradle the rebar and are embedded in the rebar as the lock-shear bolts are tightened. The heads of the lock-shear bolts are designed to shear off at a prescribed torque in order to accomplish proper installation.

Frequently Asked Questions

Rebar couplers are mechanical connectors used to join reinforcing bars (TMT bars) end to end, instead of overlapping (laps). Couplers provide full strength continuity, reduce congestion of rebar, improve concrete flow, cut down on steel and labour costs, and minimize errors in installation.

JB Engineering offers a wide range of couplers (and related products) including parallel-thread rebar couplers, Bar-Lock couplers (lock-shear bolt types), and others. Sizes cover TMT/Rebar diameters from **8 mm up to 50 mm**.

Yes. JB Engineering's manufacturing plants are **ISO 9001:2015** and **ISO 14001:2015** certified.The products are also approved by major Indian infrastructure agencies and agencies such as NHPC, NTPC, NHAI, DRDO, DMRC, etc.

Some key benefits include: - Reduced rebar congestion & improved concrete flow.
- Simplified structural detailing.
- Faster installation and reduced labour costs.
- Better quality control.
- Strength development that is independent of concrete, providing ductility especially in seismic zones.
- Cost savings up to approximately **25%** in many civil construction projects.

Installation requires the rebars to have square-cut ends in case of parallel thread-type couplers. For Bar-Lock couplers, special grip rails and lock shear bolts must be used, bolts torqued to prescribed values and heads sheared off as per guidelines. Proper tools (torque wrench, thread cutting / threading tools, etc.) and trained personnel are necessary to ensure performance. JB provides engineering support.

Yes. JB couplers are designed to perform like continuous reinforcement and provide ductility, which is crucial in seismic events. Their mechanical joint action gives strength independent of concrete where needed. They are suitable for civil structures subjected to dynamic loads.

While couplers may have a higher unit cost compared to simply overlapping rebar, they reduce material waste, reduce labour and formwork costs, improve speed of construction, and reduce errors. Overall, JB Engineering estimates cost savings up to **25%** in many civil construction projects.

Some limitations include: - Very small diameter rebar below 8 mm may not be supported.
- Tight spaces where threading or installing couplers is difficult.
- Projects with negligible loading where simpler steel detailing suffices may not benefit significantly.
- Requirements of certain codes or local construction specs may restrict certain types of mechanical couplers unless tested. Always verify with structural engineer or client.
