To break the axes of the columnar foundation, a clasp is used-a box of boards nailed to columns at an altitude of 60-80 cm. The columns are located in a step of 2-3 m. Cloves are driven into the boards in the boards at the location of the axes of the foundation. The nails are connected with a thin rope, which will denote the axis. If you hang the plumb line at the intersection points of the rope, he will definitely indicate the position of the column of the foundation, which is fixed with the peg.
