• The columns and beams are the load-bearing, structural backbone of a bottle school. Their proper assembly and pour are essential to a structurally sound and secure building.
• Measurements for the rebar to use in each column, as well as the joints in the column, depend on the size of the column. Depending on the particular construction plans you use, some may use braces of 1/4” with iron of 3/8”, and other may use 3/8” braces with 5/8” iron.
As always, check your construction plans (which have been rigorously tested and approved by a structural engineer) to ensure you use the correct thickness of rebar.
