How do you design a staircase to make the stairs a beautiful setting for your home? This time you have to know the specifications of the staircase design, staircase design specifications include a high degree of stair stepping, stair slope and width of the stairs. Here we give you a brief introduction:
Stair height standards:
The maximum stair step height is h, and the most comfortable step size is: b+h=450mm b+2h=600mm For example, if the tread is 280mm, the step height is 160mm, if the tread is 300mm, the stair is still in step. The best height is 150mm. There is a specific formulation in the specification, and the proportion of some special stairs may reach 620mm. 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.
The slope of the stairs:
The determination of the slope of the stairs should take into account the factors of walking comfort, climbing efficiency and spatial status. The line at each step of the bench at each step is called the slope line. The angle between the slope line and the horizontal plane is the gradient of the stairs (the tangent of this angle is called the gradient of the stairs). The slope of the indoor stairs is generally 20 degrees - 45 degrees, the best slope is about 30 degrees. Stairs for special functions require different slopes. For example, the slope of the ladder is above 60 degrees, the special stairs are generally taken from 45 degrees to 60 degrees, the slopes of the indoor and outdoor steps are from 14 degrees to 27 degrees, and the gradient of the slope is usually below 15 degrees. Generally speaking, in places with large crowds, high safety standards, or ample areas, the slope should be gentle. For an auxiliary staircase that is only used by a few people or is not frequently used, the slope can be steeper, but it is better not to exceed 38. Degrees, in addition to personalized stairs or because of the space to choose to spiral stairs.
The width of the stairs:
The width of the bench should be appropriate, and the general bench is calculated according to 0.55+(0~0.15)m per person flow. That is to say, for a flight of stairs, the width of the ladder should be 1.1m~1.4m for the two people to move up and down at the same time. The width of the stairwell (the width of the ladder well is 0.1m and the room reserved by the handrail of the handrail is 0.1m) should be 2.4m~ 3.0m. In addition, continuous steps should not exceed 18 steps. Now people have higher requirements for quality of life, and the design of stairs is not just reasonable in size. Many projects require stairs with landscapes, especially open spaces. Plants are planted on both sides of the stairs. The lightness of the stairs and the permeable railings all make the stairs feel less boring and tiring.
Xiao Bian summary: Stair height standards and how to design the slope and width of the stairs are introduced. I hope I can help you. For more information, please pay attention to this site.
