Stairs are channels for the rapid movement of gas, which can make the gas move quickly from one level to another. When people go up and down the stairs, they will stir the gas energy, which will make the stairs move quickly, so as to achieve the purpose of gathering gas and nourishing gas. In order to achieve this goal, the smaller the slope of the stairs, the better the effect. In order to avoid wealth and luck rushing down the stairs, indoor stairs should be as straight as possible, and spiral stairs or curved stairs with broken lines (that is, stairs with rest platforms) are the best. Of course, what kind of stairs to make depends on various other factors. For example, the decoration style of room space, the owner's personal hobbies. From the practical and aesthetic point of view, these stairs also have their own advantages and disadvantages.
Spiral staircase: The advantage of this staircase is that it saves space and gives people a better feeling and is artistic. For indoor application, it is best to rotate the spiral staircase 270 degrees. If the rotation angle is too small, there is no problem going up the stairs. For example, the stairs are too steep to walk. Although the spiral staircase is beautiful, it is not very practical. If there are old people and children at home, it gives people a sense of insecurity. This kind of stairs is mostly used for small duplex in the attic, but less for large duplex.
Folding staircase: At present, this kind of staircase is widely used indoors, and its forms are also varied. There are 90-degree folding ladders, 360-degree folding ladders and even double folding ladders (the entrance and exit have a 9-degree folding shape). The advantage of this staircase is that it is simple and easy to shape. The design should be good and the railing structure should be properly matched. The disadvantage is that, like the arc ladder, it needs more space.
Arc staircase: It connects the upstairs and downstairs with a classic line. Walking is beautiful and comfortable, without the stiffness of folding ladders and the insecurity of rotating ladders. It is the most ideal staircase, but there must be enough space to achieve the best effect. It is the first choice for large duplex and independent villas.
