Types of ramps

Ramp and step entrance
The slope value of the accessible ramp of the staircase should not exceed 1:12, and the maximum height of each slope section is 750mm, and the maximum horizontal length of the slope is 9000mm. When the length exceeds, a rest platform needs to be set up in the middle of the ramp. The depth of the rest platform should not be less than 1500mm when going straight or turning, and a wheelchair buffer zone with a depth of not less than 1500mm should be left at the starting and ending points of the ramp.
The width of the ramp should first meet the evacuation requirements. When the ramp width is not less than 1.00m, it can ensure the passage of a wheelchair; The width of the ramp shall not be less than 1.20m, ensuring that one wheelchair and one person can pass sideways; When the width of the ramp is not less than 1.0m, it can ensure that a wheelchair and a person can pass in front of each other; When the width of the ramp is not less than 1.80m, it can ensure that two wheelchairs pass through opposite directions.
