Lap length is the length overlap of two rebars tied to extend the reinforcement length. Lap length of about 50 times the diameter of the bar is considered safe. Laps of neighboring rebars should be staggered and should not be provided at one level/line. At one cross section, a maximum of 50% rebars should be lapped. In case, required lap length is not available at junction because of space and other constraints, rebars can be joined with couplers or welded with correct method of welding.
Rebar Couplers
For many years the use of mechanical couplers to join reinforcing bars has been regarded as a means of reducing the use of long bars. Engineers and contractors now recognize the benefits of using Reinforcement Couplers to accelerate the speed of construction, increase productivity and simplify structure design details.
