Introduction

Industries, Production Units and manufacturing units are growing rapidly in numbers and so are the equipment needed for the process. it is a rod or link transmitting force and motion between a rotating part . The primary purpose of couplings is to join two pieces of rotating equipment while permitting some degree of misalignment or end movement or both. It is used to connect two things And in construction machines to allow the rapid change of buckets. The main purpose of coupler manufactured by SPROCS FORMWORKS is “Easy Maintenance” Coupler couplers are used to connect two threaded rebars. As time going, couplers have replaced the traditional lap joint splicing. And now, more and more engineers are recommending mechanical rebar connection over lap splices. People have found that rebar mechanical connections afford reliability and consistency that can’t be found with lap joint splicing. Rebar mechanical systems care more reliable than lap systems because they don’t depend on the concrete for load transfer.

Features of couplers
Coupler reduces consumption of steel and it increases tensile and compressive capacity of RC structure. It also reduces congestion of reinforcement bars and reduces concrete or steel ratio and improve concrete quality by having bigger space between bars and it protects expensive system framework and avoid use of expensive starter bar boxes.it helps in avoiding bend and re-bending of bigger reinforcement bars and also helps in increasing speed of work due to faster and easier installation. Coupler saves steel, time and cost and it is eco-friendly.
Advantages
Coupler eliminates tedious lap calculations. It is fast and easy to install and requires no specialized skilled labour. They are cost-effective by reducing labour costs and accelerating job schedules. Dowel bar substitutes reduce labour on-site, formwork costs, and increase job site safety. Bar terminators eliminate congestion and simplify bar placing.

Conclusion
These are the major features and advantages of coupler manufactured by SPROCS FORMWORKS .
