MBT Couplers & Rebar Bolted couplers

 Rebar Mbt (Mechanical Biological Treatement) Couplers Are Used Only Critical Condition In Construction At The Sites Area. Critical Conditions Like Lack Of  Suitable Rebar Size Into The Concrete Where Not Only Threading Even Lapping Is Also Not Possible.

Here's The Picture Of MBT Rebar Coupler To Joining Two Tmt Bars.   

 The Tmt Bars Join with The Help of Bolts. For Joining Need To Be Drilled In The Tmt Bars. 

Here Fig 1.2 Shown There Are Only 80mm Tmt Length Remaining In Concrete. Then Tha lapping And Threading Process Of Tmt Bars In Not Possible Because for Lapping The Bars Minimum 150mm Length Is Required So There Is Lapping And Threading Is Not Possible For That Conditions The Engineers Design Mbt & Bolted Couplers.

The Material Used In Mbt Coupler Is EN8D .. EN8 Represtnt Series And D Stand For Ductile.

EN8D Material Is Best Material In Mbt Coupler And Also In Others Rebar Coupler.

Sizes Of Mbt Couplers

Basically Mbt Coupler Sizes And Other Rebar Threading Coupler Sizes Are Same But  Mbt Coupler Lengths Is Big As Compare  To Threaded Couplers.The Sizes Available In Mbt Coupler Is Standard From 12mm To 40mm. Like 12mm , 16mm ,20mm..etc

Numbers Of Bolts In MBT Coupler

The Bolts Of Mbt Coupler Is Depends On It Sizes The Minimum Numbers Of Bolts Required is 4

And Other Size And Numbers Of Bolts Chart As Given Below.

 

Coupler Sizes	No. Of Bolts Count
12mm	4 Bolts
16mm	6 Bolts
20mm	8 Bolts
25/32mm	12 Bolts

Rebar Coupler | Rebar Roll Thread Coupler | Rebar Cold Forged Coupler | Rebar Coupler Overview

Rebar couplers are used in reinforced concrete structures to replace normal rebar lap joints. The couplers are also suitable for use in reinforced concrete columns and walls. Each rebar coupler consists of a piece of rebar equipped with a thread and coupler sleeve at the right end as viewed in the direction of installation. In construction joints, rebar couplers can be used to replace all pieces of rebar going through the formwork.

Each end of the rebar to be joined is cut square and enlarged using a cold forge process. A thread is then formed on the enlarged bar end using a thread rolling machine. The thread is such that the cross-sectional area of the bar ends is not reduced ensuring the strength of the connection matches or exceeds that of the parent bars.

WHY USE REBAR COUPLERS?

The Traditional methods of lapped joints are not always an appropriate means of connecting reinforcing bars. Lapped joints are dependent upon the concrete for load transfer. The use of laps can be time-consuming in terms of design and installation and the increased amount of rebar creates congestion within the concrete.

Couplers are designed to mechanically join two bars together. By creating an end-to-end bar connection, a continuous load path is created from one bar to another that is independent of the condition and quality of the concrete. Mechanical splices are reliable under conditions of cyclic loading into the inelastic range and prove to be advantageous at the locations where inelastic yielding may occur. BENEFITS OF COUPLERS

Spliced rebar performs like continuous reinforcement due to the mechanical joint, unlike lapping which has a complete dependency on concrete.

Steel wastage is reduced significantly. Using couplers save lap-length steel. A 12m rebar can be divided into 3m or 4m as bars as required, which prevents the wastage of end pieces of steel.

Staggering of bars not required.

Bar cross-sectional area is not reduced.

Couplers are used as a replacement for dowel bars which also saves formwork material.

Steel congestion is reduced due to the elimination of laps.

Using couplers provides superior cyclic performance as compared to the lap joint.

Easy to install and no torque wrench required. FEATURES OF COUPLERS EN8D material is used for manufacturing couplers. Reinforcing bar couplers with high carbon contents that have high strength and greater thickness are more sustainable and effective. Reinforcing bar coupler helps to increase the pace of execution and the quality of projects. It can simplify the design and construction of reinforced concrete and reduce the amount of reinforcement required, which is now a valuable national resource. No torque wrench is required for assembling, reinforcing bar couplers. Hand tightening of the bar or coupler is sufficient. Our couplers can be used in power plants, bridges, and all types of R.C.C structures CODE SPECIFICATION In India, the structural consultant is free to define the code to which the couplers have used the project. I. ACI: 318 – 2008:

Type 1 joint required to achieve 1.25Fy as a minimum, e.g: For Fe500 the tensile strength expected is at least 625 N/mm2 (Clause 12.14.3.4).

Type 2 is required to comply with the 1.25Fy requirement and also meet the specified tensile strength of the rebar. E.g: For Fe500 the ultimate stress expected from the same is at At least 700 N/mm2. II. BS 8110 – Part 1, Section 3, 1989:

Specifies tensile testing and slip test for the joint for acceptance of the sample.

Testing the coupler of a precise type, the permanent elongation after loading to 0.6fy should not exceed 0.1mm. E.g: For grade 460 the tensile strength should exceed 497 N/mm2. III. IS 1786 – 2008:

Type 1 – For Fe500 is considered acceptable for use anywhere in the structure if it meets the ultimate strength of 545 N/mm2 which is much lesser than the 1.25Fy. (Clause 8.1 –Table 3).

Type 2 – The condition becomes at least 625 N/mm2 as well. IV. IS 16172 – 2014:

Rebar Coupler

 Defination- Rebar Coupler Is A Basically Mecenical Splicing system. Used In  Rebar Forging and Threading System.

Basically Rebar Coupler Is Pure Construction Related Product Mostly Use at Construction sites Like Building Constructions, Infra Projects , Bridges And Dams, The Nature Of Rebar Coupler Is Merging TMT Bars In Pillars Of Building & Infra Constructions.

Types Of Rebar couplers.

Basically There Are Two Types Of Rebar Couoler

1) Threaded Couoler

2) Non- Threaded Coupler

*Threaded Coupler - Threaded Coupler Use For To Joint The Tmt bars After Completing Threading Process Of TMT Bars, In Threaded Coupler There Are Also Two types Of Coupler .

*.Roll Threaded Couplers & Cold Forged Couplers.

In Both The System (Roll Thread & Cold forged) The Threading Of TMT Is required. But in Cold Forged Coupling System The Extra Process Is Forging.. Means for Cold Forged System Of coupling The Forging Is Require Of TMT. In This Process Firstly TMT Bars Forged by Rebar Cold Forging Machine. with The Help Of hydraulik Pressure Of Machine..

* The cold Forged Coupling System Is Known As IS Passed System All Governments Infra Projects Are Use Only Cold Forged System.

2) Non Threaded Coupler.

Non- Threaded coupler Refers To Couplers Are  Made And Fix Without Threading Process In Coupler As well As TMT Bars. In Non Threaded Coupling System Formally Two Couplers Are Currently Use.

* Mbt Coupler & Allenkey Coupler

Mbt Coupler Is Basically Designed For Only At Critical Cases.. in Mbt couplers There Are 6 to 8 Bolts And The Length Of Mbt coupler Is Almost 180mm And More Is Greater Thant Rebar Threaded Couplers.. It"s Used  when Lapline And threading Is Not Possible At construction site..

We Are The On Of The Leading Manufacturer Of Rebar Couplers At Mumbai & Hydrabad, And Dealing in All Over India And All Metros Cities Like Mumbai, Bangaluru, Hydrabad, New Delhi , Punjab, Chennai , Kolkatta , Lucknow Etc. And Formally work In Governments Projects like ISRO,

And Also Dealing with India's Top Constructions Companies Like L&T Constructions At Punjab & Maharashtra , J Kumar Infra Projects At Mumabi Metro, DBL Ind Ltd , Tata Projects Ltd, Bsr Infratech.

Etc..

We Also Have us Own Dealers In New Delhi, And Chennai And Others South Ind States.
