HOLE DIMENSIONS
If the hole exists: based on the height between the floors (H) to be connected, select from the possible staircase configurations the one compatible with the existing floor hole according to the diagram below.
If the hole still needs to be made: based on the height between the floors (H) to be connected, make the hole in the floor compatible with the configuration of the chosen staircase (straight, with one turn, with two turns) according to the diagram below.
| HEIGHT BETWEEN THE PLANS (H) |
DIMENSIONS OF THE SLOT HOLE (with slab thickness of 30 cm) |
|---|---|
| Min. 240 cm* - Max. 260 | The floor hole must have at least the dimensions of the scale |
| Min. 260 cm - Max. 285 | The floor hole must have at least the dimensions of the staircase minus 1 step down |
| Min. 285 cm - Max.305 | The floor hole must have at least the dimensions of the staircase minus 2 steps at the bottom |
| Min. 305 cm - Max. 330 | The floor hole must have at least the dimensions of the staircase minus 3 steps at the bottom |
| Min. 330 cm - Max. 355 | The floor hole must have at least the dimensions of the staircase minus 4 steps at the bottom |
| Greater than 355 cm | The floor hole must have at least the dimensions of the staircase minus 5 steps at the bottom |
| * less than 240 cm: The floor opening must have at least the dimensions of the staircase plus 1 step at the top of the staircase (bottom) | |
