How much is the size of the spiral staircase?

First, the size of the indoor spiral staircase
Spiral stairs size standard 1
Spiral staircase saves space, if the space is relatively small, in general, the smallest size of the opening of the spiral staircase can be opened to 1300mm*1300mm or 1400mm*1100mm. However, nowadays, there is only one center force point for the center column rotary staircase. Walking on the outside, this structure will cause the tread plate to move up and down. This is a common disadvantage of the Zhongzhu Rotary Stairs. If the travel radius of the stair is larger, the pedal will shake more. The load bearing capacity of the spiral staircase is generally 150kg to 200kg, compared with the weight of other finished steel-wood staircases generally around 400kg.

Step height and depth: The step height should be 15-18 cm and the step depth 22-27 cm. The order is about 15 steps. If it is too high, you may need to set up a stair rest platform.

The steps are controlled to 20-30cm. The highest step to the height of the ceiling requires a clearance of 2m or more and a minimum of 1.8m. The distance between the center of the two railings is 8cm, not more than 12.5cm, the height of the armrest to the waist, 85-90cm, and the diameter of the handrail is 5.5cm.
Second, design should pay attention to the problem
1. In order to avoid illusions when the stairs are rotated up and down, the heights of the first steps and the last steps of the stairs should be the same as those of other classes. If you need to change, you should control within 4 cm, preferably not more than 2 cm to 3 cm.
2. The maximum height of a spiral stair to the height of the ceiling requires a clearance of two meters or more, and a minimum height of 1.8 meters. Otherwise, there will be a sense of pressure.
3. Rotate the distance between the balustrades: The distance between the center of the two balustrades should be 8cm and not more than 12.5cm so as to prevent the child from sticking his head out of the gap.
4, rotating staircase handrail height: to the waist position, 85 ~ 90 cm, armrest diameter of 5.5 cm is better.
5, the height and depth of the spiral stairs ladder: step height should be 15 to 18 cm, step depth of 22 to 27 cm. The order is about 15 steps. If it is too high, you may need to set up a stair rest platform.
6. Spiral Stairs Spiral Stair Width: When one side is empty, the net width is not less than 75cm; when there are walls on both sides, the net width is not less than 90cm.
7. Rotary safety: The stair components should be smooth and rounded without protruding or sharp parts. For families with children and elderly people, the slope of the stairs should be gentle, and the angle of rotation should not be too large; the anti-skid measures such as non-slip strips, non-slip mats, and non-slip grooves should be used for stair treads.
