Crank is a slight bending in bars at the lap so that maintains the clear cover even at the lap position. The rule that is generally practiced is that the slope of crank 1:10 & minimum length of crank 300 mm.
Crank length of reinforcement
Formula of Crank length = (d1+d2+5)*10mm
d1 =diameter of smaller bar d2
= diameter of largest bar
= diameter of largest bar
What is minimum length distance of rebar from the face of support before we can crank the rebar? Thank youvin advance for response.
Please led me know What is 10mm?. Is it Standard or Dia Of the Bar
Is it 1:6 or 1:10 whic is the correct
