Stairs are passages that allow people to go up and down two spaces smoothly. It must have a reasonable structural design. According to the standard, each step of the staircase should be 15 cm high and 28 cm wide; the designer is required to have a thorough understanding and mastery of the size in order to make the design of the stairs easy to walk and occupy the least space . Let’s take a look at the relevant information about staircase design.
1. Design of indoor staircase step gradient
Generally, the slope of the steps will be determined by the height of the house and the size of the space beside the opening. What is the slope of the stairs? That is, the angle between the straight line and the horizontal formed by the front of the indoor stair treads. This inclination is standardized to about 30 degrees, which is also the most comfortable angle, and it is better to be flat.
2. Interior staircase design
The specifications of indoor stair slabs cover two kinds of treads and risers, which are required to be compatible with the size of human feet. Like the pedal type, the step with low riser is more comfortable for people to walk. The width of the pedal is required to be greater than or equal to 24cm, 28cm is the most comfortable size. The height of the stair riser should be less than or equal to 20cm, and the size of 18cm is the most comfortable. If the width of each pedal is different from the height of the vertical board, it is easy to cause people to fall, so the width of the pedal and the height of the vertical board are required to be the same.
Three, interior staircase step length design
Staircase design specifications are established in the staircase industry. Even if they are frequently mentioned, the indicators are still uncertain. They are only examples of large staircase companies. Therefore, the so-called stair design specification does not have specific hard standards.
Although there are no specific rigid standards in the interior staircase design specifications, the above three specifications are still the most satisfactory after verification by major staircase companies, and the stairs designed according to this specification are also the most comfortable. Therefore, those who want to design stairs for their new homes may wish to refer to these major specifications.
