1. How big are the stairs?
According to the relevant regulations of the state, the width, height and width of outdoor stairs in public buildings should not be less than 30cm, 15cm and 10cm respectively. The width of stair tread in residential buildings should not be less than 260mm, the height should not be greater than 175mm, and the clear width of stair tread should not be less than 1. 1m ... The slope of stairs is between 20 and 45 degrees, and the common step size is 300×150 mm.
Second, what should I pay attention to in stair design?
1, when designing stairs, you can choose the location and style of stairs according to indoor lighting, house size, moving lines and other factors. For example, we can design the stairs against the wall and try not to set the stairs in the center of the house. When designing stairs, if the indoor space is small, you can choose spiral stairs that save area. If the indoor area is enough, you can choose curved stairs and folding stairs.
2. When designing stairs, we should also pay attention to whether the relevant dimensions of stairs conform to ergonomics. For example, the step depth of stairs should not be too small, the step should not be too high, and the slope of stairs should not be too steep, otherwise it will be very difficult to go up and down the stairs, and there may be problems such as stepping empty. The size of each step of the stairs should be consistent, and the height of the steps is not suitable, which is not conducive to going up and down the stairs.
3. When designing stairs, we should also pay attention to the safety of stairs. For example, we can install induction lamp on the wall near the steps, and you can see it when you go up and down the stairs. Stairs can be equipped with handrails, and the spacing between handrails should not be too large. Stairs can be made of non-slip thread or carpeted to avoid slipping up and down stairs.
