The stair step size is actually the step size of the stairs. When going up and down the stairs, the stair step size is quite critical, or the big or small affects the safety of the stairs! Let's let the decoration home decoration network Xiaobian introduce relevant knowledge for everyone!
The new school has a "hard indicator". Each step of the stairs must not exceed 18 steps. Specifically, the main construction contents of the pre-school district planning are the school gate, the transceiver room, the pre-school square, the green square, etc.; The content is the teaching building, the experimental building, the library, the scientific research building, etc. The main contents of the student living area planning are the student apartment, the student canteen, the activity center and the student living auxiliary room; the main contents of the sports area planning are the gymnasium and swimming Pavilion (pool), track and field stadium, basketball court, volleyball court, badminton court, etc.; the main contents of the office area planning are the school, the department's administrative office, and the teacher's office.
The scale of the step should generally be adapted to the scale of the human foot and conform to the function of the stairs in the buildings of different places. The ratio of the height to the width of the step is the gradient of the stairs. Steps can have different values ​​under the same slope. The most important thing is to ensure the comfort of the stairs. Therefore, it is necessary to establish a suitable size.
Stair step size: In life, the steps that are comfortable when walking are usually small and wide. Therefore, when selecting the aspect ratio, it is better to use the two scales of the same slope as the height. However, it should be noted that the width should not be too small, and it should be no less than 240mm. This ensures that the center of gravity of the foot falls on the periphery of the foot and that 90% of the heel is on the step. For adults, the minimum width of the stair step should be 240mm, and the appropriate width should be about 300mm. The height of the step should not exceed 170mm, and the comfortable height is about 150mm.
Second, the kindergarten stair size
In the past, the key part of the kindergarten decoration environment is decorated with stairs. Generally, the kindergarten floor is cut and decorated according to the size of the building. In this process, not only the difficulty of paving is increased, but also a lot of floor materials are wasted. If the technology of the workers is not up to standard, then the effect of the decoration will be very poor. Sometimes, it will not take long for the bulge to crack, which will not only affect the overall aesthetics, but also bring hidden dangers to the children.
Kindergarten stair steps to match the color of the kindergarten floor, adding a new impetus to the overall environment of the kindergarten. There are also colored anti-slip bars on the top to increase the aesthetics, make the stair parts more eye-catching, remind the children to walk safely, and the brightness of the anti-sliding bar can also be good when the light is insufficient. The safety of the stairs is guaranteed.
The width of the ladder is usually determined by the flow of the passer to ensure that the passage is smooth. The width of a single-passage step should normally be 800-900mm; the width of a double-passage step should normally be 1100mm--1400mm; the width of a three-passenger step should normally be 1650-2100. If more people are in circulation, add 550+ (0-150) mm width per person flow. When the width of the step is greater than 1400mm, it should normally be placed against the wall handrail, and when the stairs exceed 4-5 people, the center handrail should usually be added.
For each step of the same staircase, the height and width specifications of the steps should be the same, and the scale should not be changed irregularly to ensure the stability of the slope and the stride.
The net width of the stair treads shall not be less than 1.1m except for the width of the step. The height of the stair handrail should not be less than 1m; the height of the outdoor stair handrail should not be less than 1.05m, starting from the bottom of the tread. When the stairwell width is greater than 0.2m, the vertical clearance of the handrail should not exceed 0.2m, in case the child falls because the gap is too large.
The width of the ladder is also clearly defined in the design and must meet the needs of fire dispersion. The construction of the treads in public places should reflect that the width of the stairs is usually too large, but pay special attention to the contact between the handrail and the width of the ladder. That is to say, the stairs should be provided with armrests on at least one side. When the net width of the ladders reaches three streams, handrails should be provided at both ends. When four streams are flown, intermediate handrails should be added.
The above is the decoration of the home decoration network Xiaobian for everyone to introduce the knowledge of the stair size , I hope to bring convenience to your life, more exciting, please pay attention to the decoration encyclopedia!
