2008-11-16 11:16 pm
假如落鐵時係 2T8-3-200FF, 中間個3代表乜野呢? 咁200 係spacing, 後面個FF 又係乜野黎架, 因為有時見佢唔係FF, 而係T , 點解呢?

2T8-3-200FF
2T8 = 2 nos. of 8mm dia. high yield (T) rebars
2R8 = 2 nos. of 8mm dia. mild steel (R) rebars
3 = bar mark
200 = c/c spacing
FF = far face (Not front face ar)
T = top layer
2T8 = 2 nos. of 8mm dia. high yield (T) rebars
2R8 = 2 nos. of 8mm dia. mild steel (R) rebars
3 = bar mark
200 = c/c spacing
FF = far face (Not front face ar)
T = top layer
