In this video Er. Mayank Saini, Corporate Trainer of Civil Guruji Explaining about Lapping, Coupling & Gas Welding Joint with Cost Difference in steel Bars.
Due to the increased complexity of construction and design specifications, the need for a more robust splicing method has become more evident in recent years. Using reinforcement rebar couplers will simplify reinforced concrete design and construction and reduce the amount of reinforcement needed. Rebar couplers have important advantages over lapped joints.
The coupler with its evidence stressed bar ends guarantees full performance splicing joint. The extended long thread simply turns the coupler instead of the bar itself to provide swift installation. Although lap splicing is largely dependent on the load transfer bond between concrete and steel, the coupler with its specific parallel thread ensures a positive alignment locking relation, thereby providing a continuity load path and structural integrity. Throughout strain, friction and stress reversal conditions, the coupler serves as a continuous length reinforcement bar by facilitating full strength.
Strict compliance with the current standards of concrete architecture. Coupler use reduces repetitive calculations in order to determine the right lap lengths. Skid steer flat face couplers also eliminate possible design defects by up to 40 percent while reducing waste and excessive rebar costs. In fact, it also significantly reduces pollution, while maintaining a healthy ratio of balanced steel to concrete. This is almost unlikely due to the additional rebar in the lap zone with lap splicing.
Standard Length of a Reinforced bar is 12m, Suppose if you are constructing high rise building, 1 bar length is not sufficient for entire building height. So You need to join bars during execution time as per design.
Mechanical couplers are widely used in the present construction industry to joint two reinforcement bars together. The lapping of reinforcement is very difficult and time-consuming. Further, some costs also can be saved with mechanical couplers. In addition, it is a saving of materials and very useful in the areas where the reinforcement is congested.
It is a replacement for the reinforcement laps. As we all know, based on the position we lap the reinforcement, we should have to provide compression lap length, tension lap length, or modified tension lap length based on the position we lapped.
When we are doing the curtailment of reinforcement, we cannot avoid the lapping. Further, as per the seismic detailings reinforcement congestion increases at joints.
Mechanical coupler solves these issue and it is just a matter of a few minutes.
At site or at the plant we can lap the reinforcement without providing typical lap lengths.
