A, stair design specification requirements:
1. According to the standard of the stair design code, every step of the stair should be 15 cm high and 28 cm wide, which requires the designer to have a thorough understanding and mastery of the size, so as to make the stair design easy to walk. According to the actual situation, the stair tread height should be less than 18cm and the width should be greater than 22cm.
2. From the formal point of view, stairs can be roughly divided into three types. The straight ladder is the most common and simple, and it has a taste of going its own way. Geometric lines give people a "hard" feeling, and straight ladders and platforms can also turn corners. The arc ladder, which connects the upstairs and downstairs in a curve, is beautiful and can be made very wide. It is the most comfortable one to walk. The spiral staircase takes up the least space, and the winding trend of spiral rise is really charming.
3. The choice of stairs should be arranged according to family members. Old people and children are the people who need to be taken care of most in the family. They probably prefer that the slope of the stairs is slower, the pedals are wider, or the rotation of the stairs is not too strong, so that they will feel at ease when going up and down the stairs.
4. Carefully observe the height difference between the first step and the last step of stairs. These two steps are not only the connection point of the upper and lower space, but also the support point of the stairs, and they are the most critical places in the whole stairs. On these two levels, the most common problem is that the step height in the middle of the stairs is inconsistent with other levels.
5. Most people have the feeling of tripping or trampling on the stairs, both of which will make people feel cold and cold. Because when people go upstairs and downstairs, the sense of rhythm has been stored in their minds, which becomes a natural thing. If this time is suddenly interrupted, and it is on the steep surface, it will definitely bring terror.
6. The reasons for the ups and downs are not complicated. If it is a prefabricated staircase, the step height of each step can be calculated by dividing the space height by the length of the staircase. However, if it is a post-processed staircase, the space is fixed, and the accessory size of the staircase is prefabricated, then the two fixed sizes are definitely contradictory. Only the size of the stairs can match the size of the space. This is inevitably inappropriate.
Secondly, let's take a look at the matters needing attention in the stair design code:
1, Aesthetics When designing stairs, we should first consider its aesthetics. Since it is a decorated villa, the owner's requirements for the home environment will not be too low. At this time, the stairs should not only play the role of connection, but also decorate the whole home environment prominently.
2. Safety stairs play an important role in the home environment. On the one hand, it connects the whole home environment, on the other hand, it plays the role of decoration and embellishment. If there are old people or children in the host family, we should pay more attention to the safety performance of the stairs.
Practicality is also a factor that we must consider. The so-called practicality means that when going up and down stairs, you should meet the requirements of convenience, conform to the laws of human movement, and move freely at every step. On the contrary, if the interval and corner design of stairs are unreasonable, it will bring great inconvenience to people.
The design of stairs can only show its beauty if it is combined with design norms and makes rational use of space.
