Wangshan fortune-telling

25 steel bar, I don't know the length of the wall, so I suggest adding two more cantilever beams, using hollow brick wall on the second floor, opening more windows to reduce the weight, and increasing the foundation appropriately.

If 12m steel bars are used for ground beam and ring beam, there are 39 steel bars, 18 for ground beam and 14 for ring beam. For empty beams, there will be 1 1 root 12m steel bars and 14 or 16. Main reinforcement of protective layer 100, negative reinforcement 100, 12 or 14 thick, and 30 groups of steel bars are long 10 m.
