Why are the stairs singular? How many steps at most?

Stairs are passages connecting the upper and lower floors. The design of stairs is very important in villas and duplex buildings, especially the number of stairs, which will have an impact on the geomantic omen of houses. In many places, there is a saying that stair steps must be singular, so why are stair steps singular? What is the maximum number of stairs? Let's give you a detailed answer.

Why are stairs and steps singular?

1, from the perspective of geomantic omen.

It's odd, it's Yang. Double is Lian and Yin. Houses are divided into Yin and Yang Zhai Zhai Zhai, Yang Zhai is singular and Yin Zhai is even. Singular people think it is auspicious, so the number of stairs is generally singular. This is the traditional architectural culture of China.

2. From an architectural point of view

The most reasonable number of stairs is not less than 3 (unnecessary) and not more than 18 (too high and uncomfortable). In order to make the stairs occupy less space, the stairs are usually designed as double steps, that is, a rest platform is made in the middle, so that the number of steps of each staircase is 9 steps.

3. From the behavioral habits.

Everyone's habits prove that singular is more in line with people's walking habits. That is, when people walk the stairs, which foot is the first step and which foot is the last step, so it won't be so awkward! Walking will be much more natural. If you don't believe me, try even steps. Is it a little uncoordinated to close your right foot and your left foot?

What is the maximum number of stairs?

Generally, the number of stair steps should not exceed 18, and should not be less than level 3.

The general order of stairs and steps is not necessarily a single order. Generally, after determining the height of a single step, add it directly, and finally adjust the height appropriately. No one deliberately insists on a single step.

Calculation method of stair sequence: First, confirm how many turns are needed from the first floor to the second floor. If you need to turn, you need a rest plane. Then, confirm the height of the rest platform from the ground, mark the position with ink lines, measure the length from the starting point to the rest platform, and then calculate the order according to the size of the first point. The sequence calculation method from the rest platform to the second floor door is the same as above.

These are the reasons why the stairs are all singular. No matter from the perspective of geomantic omen, architecture and behavior habits, the stairs are singular, which is not only auspicious, but also more convenient to walk. Generally speaking, the number of stair steps should not exceed 18, nor should it be less than 3, so it is better to choose an odd number when designing stair steps.
