1. What is the height of the handrail?
1, from the point of view of our normal walking, we should measure from the steps, and the indoor stair handrail should not be less than 90cm to meet the convenience; And outdoor stairs, generally not less than 105cm.
2. When the width of the stair railing is greater than 0.2m, the clear distance between the stair railing columns should not exceed 0. 1 1m, otherwise children will easily fall down due to leaning and climbing.
3. When designing stairs, the platform width of stairs should be greater than the width of steps, and at least ≥1.1m..
4. In kindergartens, primary and secondary schools and children's activity areas, in order to prevent children from climbing accidents, anti-climbing design should be adopted, and the distance between two columns should be less than 1 1cm when making columns.
5. In terms of height, if the free height of stairs exceeds 24m, the height of stair handrails should be at least1.1m; When the height is less than 24m, the height of stair handrail cannot be less than or equal to1.05m.
6. If it is a place where children are allowed to enter, such as entertainment, physical fitness, garden landscape, etc. Safety should be considered when making handrails. When vertical columns are also made, the distance between two columns should be less than 1 1cm.
Second, how to measure the height of the stair handrail?
1, bullet line
Playing ink lines is one of the most commonly used methods. We translate the chalk line vertically by about 150, and we can get a vertical distance of the chalk line, which is often said that the height of the step template is 150.
2. Play the cascade mode board line
We need to use a level. We divide the ink line into nine equal parts and then make a vertical line in each equal part. After equal division, we can get the template line of each step according to the line marks.
3, play oblique chalk line
If you are not used to the above two methods, you can try this oblique inking method. Measure a step height point 150 at the intersection of the horizontal line and the ink line with elevation -0.02, and connect this point with the horizontal line and the ink line with elevation 1.48.
