How PER JOINT COST of Butt Joint Different from Overlap & Rebar Coupler Cost ?
Overlapping Cost:
Overlap is a traditional method in this two rebar are overlap for a particular length as per recommendation IS 456:2000. overlapped rebar is tie with binding wire and the overlap cost depends on rebar diameter if column rebar diameter increases overlap cost will increase Here are the rates per overlap bar for different bar diameter: Steel rate= 61₹/kg
| Rebar Size (mm) | Per Joint Cost (₹) |
| 12 | 32 |
| 16 | 77 |
| 20 | 151 |
| 25 | 294 |
| 32 | 616 |
Rebar Coupler Cost:
Rebar couplers are mechanical components that are used to join two steel reinforcing bars (rebars) together. Rebar coupler recommend by IS 16172:2014 it provide an alternative to conventional lap splicing, In which overlapped bars need more space during lapping. Here are the rates of rebar coupler for different bar diameter:
Rebar Size (mm) | Coupler Cost (₹) | Rebar Threading Cost (₹) | Total Cost (₹) |
12 | 25 | 11 | 36 |
16 | 40 | 19 | 59 |
20 | 50 | 30 | 80 |
25 | 110 | 47 | 157 |
32 | 190 | 76 | 266 |
Butt Joint Cost:
As per IS 9417:2018 two reinforcing bars are joined together using the Butt Joint Method. A strong continuous joint between the bars is made by applying pressure and electric heat to the joint. Butt Joint Technique is widely used in construction projects now a days. Here are the rates of Butt Joint for different bar diameter:
Rebar Size (mm) | TMT Loss (₹) | Flux Cost (₹) | Labour Cost (₹) | Butt Joint Cost (₹) |
12 | 1 | 7 | 3 | 11 |
16 | 1 | 8 | 4 | 13 |
20 | 2 | 10 | 5 | 17 |
25 | 3 | 13 | 6 | 22 |
32 | 4 | 18 | 8 | 30 |
Conclusion
Butt Joint Machine is a Onetime Investment that will offers a Cost-Effective solution compared to Overlapping joint and Rebar Coupler. The butt joint method is Efficient, Easy to Install, and lower maintenance requirements contribute to their economic advantage.
