Coupling of reinforcement in column & beam🏗️┃सबसे अच्छा सबसे सस्ता🤑┃Coupler Vs Lapping cost analysis

A rebar coupler is a technical product that is necessary when long length of bar is required. The primary work of this coupler in reinforcement is to join two TMT bars for continuous reinforcement. The rebar coupler is used in all the construction fields, such as, constructions of buildings, bridges, dams, towers, etc.

Rebar couplers are used in the RCC structures to replace the system of lapping and welding in reinforcement. When there is need of long length bars or when joining the additional bars to the end of existing bars, the lapping system is applied that is the bars are tied by wire next to each over. In the same way like lapping, welding is also processed where unlike tied by wire, the bars are attached by welding.

Since, there is a wastage of bar in lapping system and welding system, an alternative system is used known as rebar coupler or the coupler in reinforcement that provides an end to end connection for the continuous reinforcement of a structure. The coupler in reinforcement is used since it is economical and cost efficient unlike the lapping system, where some part of the bar is wasted due to lapping.

The rebar coupler is particularly cost efficient for large diameter bars in the big projects of construction and construction of skyscrapers. The rebar couplers are also commonly known as mechanical splices. The rebar coupler is used in all the construction fields, such as, constructions of buildings, bridges, dams, towers, etc.
Types of Rebar Coupler

Threaded Rebar Coupler
Roll Thread Rebar Coupler
Cold Forged Rebar Coupler
Non-Threaded Rebar Coupler
Crimping Rebar Coupler
MBT Rebar Coupler

In roll thread rebar coupler, the coupler is threaded by threading machine. To fit the bar in the roll thread coupler in reinforcement, the ends of the TMT bars are threaded in the Roll Thread Machine. After that the rebar coupler installation is done to the both ends of the TMT bar like nut and bolt, for the continuous reinforcement.

Cold Forged Rebar Coupler
Like the Roll Thread Rebar Coupler, the Cold Forged Rebar Coupler is also threaded by the threading machine. But in this coupler in reinforcement, the end of the TMT bar is forged by forging machine with the help of hydraulic pressure.

After the process of forging the end of TMT bar losses a minimal part of length and increases its thickness and then the bar end is threaded by the threading machine and fitted to the rebar coupler.

The cold forged rebar coupler is passed for the big infrastructure projects and other government projects. This system is passed by the Indian Government under the BIS code IS: 16172-2014.

MBT Couplers
The MBT Rebar Coupler is basically designed for the critical conditions of continuous reinforcement. This MBT coupler in reinforcement is used when there is less lap length and not much of a bar is left for the continuous reinforcement. The MBT couplers are also used in the retrofitting constructions. There are 6-8 bolts in the top one MBT coupler.

The length of MBT couplers is more than a threaded coupler. The strength of MBT couplers depends on the number of bolts present on it and with the help of this bolts the coupler in reinforcement is installed.
