The design standards for wheelchair ramps are to ensure that wheelchair users can use the ramp safely and conveniently. Here are some key design standards summarized based on the search results:
1. Ramp width and slope
- Width: The width of the wheelchair ramp should not be less than 1200mm.
- Slope: The slope should not be greater than 1:12, which means that for every 1 meter of height increase, the horizontal distance should be at least 12 meters.
2. Ramp shape and handrails
- Shape: Wheelchair ramps should be designed in a straight or return shape.
- Handrails: Double-layer handrails should be provided on both sides, and a 100mm high safety platform should be provided at the bottom of the handrails.
3. Resting platform
- Horizontal length: The horizontal length of the starting point, end point and intermediate resting platform should not be less than 1500mm.
4. Design for special circumstances
- Pedestrian bridge or underground passage: If there is a pedestrian bridge or underground passage, a wheelchair ramp or lifting platform should be set.
5. Safety measures
- Anti-slip measures: The slope of the ramp should be flat, non-slip and non-reflective.
- Safety barriers: Safety barriers should be set up on the airside of the wheelchair ramp.
6. Signage
- Accessibility signs: Wheelchair ramps should be equipped with barrier-free signs so that wheelchair users can easily find and use them.
The above standards are intended to ensure the safety and ease of use of wheelchair ramps, thereby improving the quality of life of wheelchair users. These standards should be strictly followed when designing and constructing wheelchair ramps.
