Indoor staircases are now an important part of interior design. There are more and more modern villas and penthouses. Therefore, the design of stair tread size is an important highlight of home design. In fact, in many public places, we will find that some stair tread sizes are not ergonomic, and it is not comfortable for us to walk. So, what is the size of the stairs? Next, Xiao Bian gave everyone a talk about stair tread size specifications and stairway design specifications.
Stair step size specification
The size of the step should generally be commensurate with the size of the person's foot, but also related to the use of features in different types of buildings. Step size includes height and width. The ratio of step height to width is the gradient of the stairs. Stepping under the same slope can have different values ​​and give a proper range to make people feel comfortable when walking.
Practice has shown that walking in a comfortable step is generally smaller in height and wider in width. Therefore, when choosing the aspect ratio, it is better to use the smaller height for the two dimensions of the same slope, because it is more labor-saving to walk than when the height and width are large. However, it should be noted that the width should not be too small, preferably not less than 240mm. This will ensure that the focus of the foot will fall close to the center of the foot and 90% of the heel strike force will be on the way. For adults, the minimum width of stairs should be 240mm, and the comfortable width should be about 280-300mm.
Staircase National Standard Step Size
The step height of the public staircase is 160-170mm. The common cement base stairs in the home are based on this standard, and the comfortable height is about 160mm. According to the current domestic market for the sale of finished stairs, the height is generally 170-210MM, about 180MM is the most economical choice; the steps of the same staircase, its step height, width size should be the same There should be no irregular changes in dimensions to ensure a constant relationship between slope and stride.
Stair step size design specifications
1. The design of stair tread size is suitable for the slope of stepping. However, the slope is determined by the height of the floor and the size of the hole around the hole. The angle between the straight line and the level formed in front of the stairway is the slope of the stairway. The inclination of the indoor stairs is about 30 or so to walk up and feel comfortable and safe.
2, stair step size design specifications include pedal and vertical plate specifications. The size of the stairs meets the size of the human foot. The stairs are more comfortable when walking. Then the width of the indoor stair step size is generally the most comfortable at 28 cm. The height of the riser is generally the most comfortable at 18 cm.
3, the size of the indoor stair step size is generally 90 cm, is the most comfortable and safe for people to walk. This design makes walking comfortable. Although stair design specifications are often mentioned, there is no definitive indicator. In particular, the stairs in the home still have to be designed according to the conditions of the family.
The above is an introduction to the relevant content of the stair tread size specification. I hope to help you. For more information on stairs, please continue to pay attention to information on this site.
