How many flights of stairs did you run from the plane?

The number of stairs in the floor plan of architectural drawings is judged according to the number of stairs bending in the floor plan. In the picture below, the stairs are bent twice, so the stairs have three sections.

Stair running number formula: Stair running number = Stair bending number+1.

Extended data:

The stair plan shows the width and length of the stair surface and the direction of the stairs, while the height can only be indicated on the elevation or marked on the plan. Labels on the floor plan need to be expressed up or down.

The surface width of stairs is different on different occasions. Generally, the minimum guarantee is 320 and the maximum is about 400. Of course, there are also 500 outdoor sizes. Generally, the height should be around 180, neither too high nor too low.

Generally, CAD software is used to draw architectural drawings, which is very suitable for drawing stair plans. At the same time, it is also applicable to draw the plan of spiral stairs. In addition, you can also choose Tianzheng building software, which can automatically generate the plane and elevation of stairs, and the popularity of this software is also relatively high.
