How many steps do I have to take to get to the rest platform?

Stairs are particularly important in the design of Gao Xiao, which determines the structure, layout and function of rooms on the first and second floors. The stairs I've always wanted don't rotate, because the elderly and future babies are most afraid. In fact, the spiral staircase is lame for me to walk by myself, and it is extremely troublesome to move things. If I move things to the second floor, I don't know what to think, so I only choose the straight stairs. I thought it was a fold. It is undoubtedly an ideal scheme for me to fold a rest platform against the bathroom wall and go up to the second floor. But when I got the design of the decoration company today, this scheme design was impossible, because the height after we finished the partition was 2.6-2.75 meters, so according to the general standard, the stair tread height was not higher than 18CM. If it is too high, the stairs are too steep. I'm afraid it's not safe to walk Then 275/ 18= 15.27 means that it needs 15, and the stair steps should be odd. The minimum width of the step is 24CM, which will be unstable if it is too small. The national standard is 28CM, so I press the minimum 24* 14 (why 65438? The width of the PASS rest platform is 80CM*2= 1.6 m, and then we calculate an account: 3.6+2 (toilet length) -3.36- 1.6=0.64 m, so the narrow distance is the width of the corridor on the second floor upstairs. Ideally, it should be at least 1.2 m, which does not meet the requirements at all. Then I thought of another plan, the stairs are completely straight, and the entrance faces the balcony, so I considered doing this. The stair tread is 16 cm in height and 25 cm in width, and the required size is 16*25=400CM, that is, 4m. Our room is 3m away from the bathroom+balcony 1.5M, that is, there is an extra rest platform for going upstairs 1M, so the width of the stairs is 80-90cm, and the lower part gradually becomes higher, which is a right triangle, so the TV can be completely put down, the refrigerator or cabinet can be placed in the highest place, and the patio opening upstairs is smaller, which does not affect the layout of the master bedroom at all. The only regret is that the downstairs looks a little crowded and uncomfortable. I saw a complete staircase, although there is a TV and refrigerator, which is very beautiful and delicious, hehe. In addition to stairs, there are 2.6 meters for placing sofas, small coffee tables and aisles. If the sofa is a little crowded, you can choose a smaller place or a higher place near the hypotenuse of the triangle, and there is still room (still 3.6 meters), haha. The method of comprehensive measurement of this staircase. Can be straight, stable and up to standard. Of course, it can be set to 18 cm high and 3.5m long, which may be a little steep. The grievance is that the living room sees the ugly stairs. But it better be beautiful, comfortable and safe. I choose the latter. It's like many products in Vienna. It looks big and ugly, but it's actually very practical and strong. After writing so much, let's search below. Remember the lesson: the height of the steps determines the steepness, while the width of the steps determines whether your feet are stable or not, and also determines the length of the space. The height and width of the steps should be designed according to the slope of the steps and the size of people's feet.

1 & gt； The gradient of stairs varies from 20 degrees to 45 degrees (not exceeding 38 degrees), that is, from 1: 2.75 to 1: 1.

2> The width of the step should ensure that all people's feet can fall on the step, and the height should be appropriate, so as to ensure the slope of the stairs is appropriate.

3> The stair step height should not be greater than 2 10mm or less than 140 mm, and the step height at all levels should be the same. The calculated value can be selected according to Appendix 3. (Figure 2.0.4)

4> The width of stair treads should be 220, 240, 260, 280, 300 and 320 mm..

Note: 250mm can be used if necessary. The clear width of the stair section should not be less than 1. 10m. For residential buildings with six floors or less, the width of stairs with railings on one side should not be less than1m.

Note: The clear width of the stair section refers to the horizontal distance between the wall and the center of the handrail.

4. 1.3 stair tread width should not be less than 0.26m, tread height should not be greater than 0.175 m, handrail height should not be less than 0.90m m, handrail height should not be less than1.05 m when the length of stair horizontal railing is greater than 0.50m, and the gap between vertical bars of stair railing should not be greater than 0./kloc-0.

4. 1.4 The clear width of the landing should not be less than that of the stair section, and should not be less than1.20m. The vertical height from the lower edge of the landing structure to the pedestrian passage should not be less than 2m. There should be a height difference between the ground at the entrance and the outdoor ground, which should not be less than 0. 10m.

4. 1.5 When the clear width of the stairwell is greater than 0. 1 1m, measures must be taken to prevent children from climbing and sliding.

Your height is not high. Generally, the height of stairs at home is about 20 cm, including those designed by big factories. Generally, the height of the attic from the ground to the floor is 2.6 meters, so some manufacturers quote in thirteen steps, each step is 20. Because I also make brand stairs, you are not tall. As for the width of the rest steps, there is no limit. If space permits, it is as big as the width of your stairs. If the stairs are 80 wide, the rest of the steps are also 80. The width of wooden escalators is generally 80- 100 cm, the inclination angle is 26-33 degrees, and the optimal inclination angle is 26-27 degrees. The tread width is 30cm, and the kicking surface height is15cm; The height of handrails is 85-95 cm, and that of flat railings is 90- 100 cm. The conventional step size of standard stairs is: 280 mm wide and 180 mm high. In general, the height and width of the steps should not be greater than 220 mm and 260 mm respectively.
