16 staircase design terms
Staircase design terminology
To start explaining stairs, you must first have a general understanding of the professional terms of stairs, and why they are rough, because when I began to sort out the knowledge related to stairs, I found that there are too many terms and names involved.
△ Staircase professional terminology
For designers, we don't need to know so comprehensively, we just need to know the information we usually use, and after sorting it out, the rest of these are the terms that I think designers need to know, and I have sorted them out.
In order to better understand these terms, let's go directly to the SU model to explain.
1. Stairwell
A space that accommodates a staircase and is limited by a wall or vertical positioning plane.
2. Stairwell opening
The horizontal distance between the width of the stairwell positioning axis and the distance on both sides, that is, the distance from 1 to 2 in the figure.
3. Flights
A combination of several continuous steps on two platforms. (Yellow area)
4. The width of the run
The horizontal distance between the edges of the run or walls perpendicular to the direction of travel. (Spacing noted in the figure)
5. Slope line
The presumed connection of the leading edges of the steps of each level in a stair run.
6. Degree
The angle between the slope line and the horizontal line, or the aspect ratio of the tread expressed by the tangent of the angle, generally does not exceed 38°.
7. Platform
The horizontal part that connects the ground floor with the end of the building section.
8. an intermediate platform
A platform located between two floors.
9. The net height of the platform
The vertical distance between the lowest point of the platform or the middle platform and the floor of the building, that is, the two bottoms are calculated.
10. The net height of the building
The clear distance between the sections perpendicular to the horizontal tread leading edge line, which is the edge of the tread on the outside.
11. Step, step wide, step high
a. Stepping: the building level composed of the tread surface and the stepping kick board (or without the kick board) to form the unit of the building section.
b. Tread width: the horizontal distance between the leading edge of the two steps.
c. Tread height: the vertical distance between two connected steps.
12. a tread surface
The horizontal upper surface of the step
13. a stepping kickboard
The vertical (or oblique) part that is connected to the tread surface
14. a stairwell
It is surrounded by the space around the flight and the measuring surface in the platform, which is the orange area.
