What are the design requirements of the steps?
6.6. 1 step setting shall meet the following requirements:
1, male * * * building indoor and outdoor step width should not be less than 0.30m, step height should not be greater than 0. 15m, and should not be less than 0. 10m, and the step should be non-slip. Indoor steps should not be less than level 2, when the height difference is less than level 2, it should be set according to the ramp;
2. When the height of steps in crowded places exceeds 0.70m and the side faces the air, there should be protective facilities.
Outdoor steps are composed of platforms and steps. The platform surface should be about 500mm wider than both sides of the doorway, 20~50mm lower than the indoor terrace, and the slope of outward drainage is about 1%.
The slope formed by the steps is gentler than that of the stairs. The width of the steps is generally not less than 300mm, and the height is not more than 150 mm. When the indoor and outdoor height difference exceeds 1 0,000mm, the enclosure railing or fence shall be set on the airport side of the steps.
The calculation method of extended data is as follows:
(1) Cast-in-place concrete steps are calculated according to the horizontal projection area.
(2) Plain soil cushion = step area * cushion thickness
(3) Lime soil cushion = step area * cushion thickness
(4) Concrete cushion = tread area * cushion thickness
(5) Step volume = Step area * Step average height
Computational difficulty
(1) The engineering quantity of special-shaped steps is not easy to calculate.
(2) aproll, steps and ramps are often intertwined, so it is difficult to calculate the area and length manually.
