Anonymous users2024-01-23The size of the balcony beam should be related to the length of the pick-out, and the beam height is about 1 6 of the length of the pick-out.
The area of 2 25 real reinforcement is 981
The area of 3 20 real reinforcement is 942
If you do not consider cracks, 2 roots of 25 are suitable.
If you consider the cracks in the bearing part, 3 roots of 20 are suitable.
To sum up, my personal suggestion is that 2 roots and 25 are suitable.

Depending on how big your house is, the 24-square-meter living room is not too small.
