WHAT IS THE SIZE OF THE SPIRAL STAIRCASE?
1, rotating stairs save space, if the space is smaller, the minimum size of the rotating staircase hole can open to 1300*1300mm, or 1400*1100mm, the current rotating staircase is basically in the column rotating stairs, its stress point only one, that is, the center of the force.To prevent the illusion of going up and down stairs, the height of the first and last step of the rotating staircase should be the same as that of the other steps.If adjustment is needed, it should be controlled within 4cm, preferably no more than 2-3cm.
2. The height of the top step of the rotating staircase should be at least two meters from the ceiling, and the lowest should be 1.8m, otherwise it will cause the user’s sense of oppression.Baluster space namely distance of center of two baluster had better maintain 8cm, the farthest cannot exceed 12.5cm, prevent child head to stick out from space place.The height range of the handrail from the handrail to the waist is 85-90cm. The diameter of the handrail should be 5.5cm.The height range of the steps should be 15-18cm, and the depth range of the steps should be 22-27cm.The number of stairs is about 15 steps. If the stairs are too high, the stair rest platform needs to be designed.When one side of the stairs is empty, the net width of the stairs should be greater than 75cm;With walls on both sides, the clear width should be greater than 90cm.
WHAT IS THE SPIRAL STAIRCASE STRUCTURE LIKE?
Spiral stairs are usually arranged around a single column, with a circular plane.The platform and the steps are fan-shaped plane, the inside width of the steps is very small, and forms a steep slope, it is not safe to walk, and the structure is more complex.
Rotating staircase saves space, if the space is relatively small, generally speaking, the minimum size of the hole of the rotating staircase can be opened to 1300*1300MM, or 1400*1100MM, the current rotating staircase is the rotating staircase in the middle column, its force point is only one, namely the center force.
How much is the size of the spiral staircase and how is the structure of the spiral staircase to explain the problem first said here, I believe that after you look at it should have more understanding, the content is only for your reference, hope to help you.
