Benefits
Experience a multitude of benefits when you choose Vruddhi Rebar Couplers:
- Cost Savings: Vruddhi Rebar Couplers offer substantial cost savings by reducing steel consumption in construction projects. This efficient alternative to lap joints not only lowers material costs but also shortens project timelines, minimizing labor expenses. The result is a significant overall reduction in construction expenditures, making Vruddhi Couplers a smart and cost-effective choice for your projects..
- Load Transfer Independence:
Vruddhi Rebar Couplers provide load transfer independence, ensuring the structural integrity of your construction
regardless of concrete quality or grade. This benefit guarantees consistent performance and reliability, reducing the risk of structural issues and offering peace of mind in diverse construction scenarios. - Project Timeline Shortening: Vruddhi Rebar Couplers expedite project timelines significantly. Their quick and efficient installation reduces construction duration, leading to earlier project completion. This time-saving advantage not only enhances project efficiency but also minimizes labor and overhead costs, making Vruddhi Couplers a valuable asset for timely project delivery.
- No Torque Wrench Required : Vruddhi Rebar Couplers offer the advantage of not requiring a torque wrench for installation. This simplifies the assembly process, reducing the need for specialized tools.
- Bar Congestion Solution: Vruddhi Rebar Couplers offer an effective solution by reducing congestion, ensuring proper concrete flow, and preventing potential weaknesses. This not only enhances structural strength but also guarantees the long-term durability of your construction projects.
- Improved Concrete Flow: Vruddhi Rebar Couplers facilitate improved concrete flow during construction. By
eliminating the need for lap joints and reducing rebar congestion, they create a smoother and more efficient concrete
pouring process.
Vruddhi Couplers Testing
Our commitment to quality is unwavering, and we subject our products to rigorous testing to ensure their reliability.
- Static Tensile Test : The Tensile strength of the mechanical splice shall be as follows:
(a) If greater than 130% of Fy; Location of failure can be anywhere
(b) If lesser than 130% of Fy; Location of failure should be outside the length of the mechanical splice(L)]
Fy = Minimum yield stress as per the rebar gradeL = 2D (D is size of rebar)] - Slip Test : Total slip for the spliced sample should be less than 0.10 mm.
- 100 Cycles Test : The rebar coupler joint shall withstand 100 cycles of stress variation, simulating the loading experienced in tall and stack-like structures.
- Low Cycle Fatigue Test : The mechanical splices shall withstand 10,000 cycles of alternating tension and compression loads.
- High Cycle Fatigue Test : The mechanical splices shall withstand 20 Lakh cycles of alternating tension and compression loads.
