Marble stair step size

The measurement method of stairs and the combination of stairs components (pedals, facades).

1, The width of the marble pedal (excluding the edge)=(the total horizontal length of the staircase + the thickness of the marble facade + the thickness of paste facade mortar)÷ the number of steps

It is worth explaining that after getting the ruler, the width of each pedal of the original pouring stair should be investigated one by one to prevent the marble pedal from being too small to be installed.If the total length of the staircase has been limited, it is necessary to use an electric pick plane small original stair wide pedals.

2, Marble elevation height =(the vertical distance between the ground on the second floor and the ground on the first floor - marble pedal thickness)÷ the number of steps

It is worth explaining that: one, the ground of the second floor refers to the ground that has been decorated (or floor tile surface, or floor surface, or cement mortar surface), because the ground that has been decorated is somewhat higher, so the relative height of the original stair facade can not be investigated one by one.

For the first step and change although also within the number of steps, but according to the actual size of the wider and longer, change too large can be divided into several symmetrical blocks.The rotating part is an arbitrarily long quadrilateral. The radius, Angle and length of the four sides should be set well.

3, The length of the marble stair combination material is 40 mm longer than the original stair, both ends of the original stair 20 mm.Decorate with the following steps.
