- - wooden bar;
- - board;
- - screws;
- - drill;
- - screw driver;
- - anchor bolts.
Instruction
1. Make necessary calculations. For calculation of necessary quantity of steps separate height of stair well into height of steps. When calculating it is necessary to consider that the spiral staircase has to have not less than 12 steps 18 cm high. Step of spiral staircase have the wedge-shaped form. The minimum length of step has to be 80 cm, width of narrow edge of step - 10 cm. The recommended height of protection of stair well - 90 cm.
