Hello, I want to ask about the design of the three stairs.

Yes, considering children and the elderly, the height of each step should not be higher than 18cm, and the width of the steps should be at least 30cm and the length should be 90cm. The total * * * can accommodate about 24 steps and two platforms.

The design is as follows:

First run: the floor is connected to the 9-step platform (90cm x 90cm).

Second run (turn 90 degrees): 6 steps to the platform (90cm×90cm).

The third run (turn 90 degrees, parallel to the first run) touches the ground in 9 steps.

I want to know what the floor height is. There are two platforms (also called steps), * * * has 26 steps, and the building height/step is the height of each step. If there are more, the length and width of the steps can be increased. Steps that are too high and too short are not easy to use. )

The building is 3 meters, and the floor thickness is about 3.4 meters. Change it to 8+4+8+2 platform =22 steps, platform to 120x 120cm, step to 30x 120cm, step to 16cm.
