The size of the stair treads should be adapted to the footwork and depth of adults, which are different in different application scenarios, and the functions between the two are related. Specifications for treads include height and depth. The ratio of step height to depth is the inclination of the stairs. The step board is installed in the same viewing angle to reduce the height of the steps or increase the depth, while increasing the length of the stairs, on the contrary, it can reduce the length of the stairs. So that everyone has a comfortable feeling when climbing the stairs, and can control the value of the stairs in an effective range. From practical experience, the comfortable steps are to moderately increase the depth of the steps and reduce the height of the stairs. Therefore, when designing the stairs and stairs, the inclination of the stairs should be reduced. For steps with the same inclination, the smaller height is used. Appropriate, because it takes less effort to walk than steps with large heights and depths. However, the depth should not be too small. If it is too small, it cannot ensure that everyone's center of gravity falls into the foot. It should be suitable for no less than 245mm. The depth of 245mm can ensure that the center of gravity of the foot falls on the periphery of the sole of the foot. Make the heels the most important thing to have on the pedals. Therefore, the depth of the steps should be 245mm, and the comfortable depth should be around 300mm. The height of the stairs should be no less than 155mm and no more than 200mm.
In each section of the same staircase, it is necessary to maintain the consistency of the height and depth of the steps, so as to ensure that the steps when going up and down the stairs are consistent, and it is not easy to give people the feeling of being inappropriate.
Stairs generally need to take into account the width of the design and production, and ensure the smooth circulation of goods. The general design plan for the width of the stairs based on the unilateral basis is 600mm and above, the width of the stairs based on the double basis should be designed to be 1200mm and above, and the stairs based on the dense flow of people should be increased to 2400mm or more, so as to ensure that the staff is not blocked to the greatest extent. congestion. When the width of the stairs exceeds 1. When it is two meters, consider modifying the guardrail at the end close to the wall.
Stair treads can be installed on stairs with a variety of inclinations, and are available in a variety of height and width specifications.
