Design Requirements for Wheelchair Ramps
1 Answers
Design requirements for wheelchair ramps: 1. Wheelchair ramps should be installed in various public and residential buildings within eco-city areas. The width of the ramp should not be less than 1200mm, and the slope should not exceed 1:12; 2. Wheelchair ramps should be designed as straight or zigzag paths, with double-layer handrails on both sides. The lower end of the handrails should have a 100mm high safety barrier; 3. The horizontal length at the starting point, ending point, and intermediate rest platforms of the ramp should not be less than 1500mm; 4. If there are pedestrian bridges or underpasses, wheelchair ramps or lifting platforms should be provided. Usage methods: Prepare adjustable ramps for ascending and descending. Ascending: When going up the ramp, the torso should lean forward. The steeper the ramp, the more the torso should lean forward to prevent tipping backward; use both arms to propel the wheelchair upward. Descending: There are two methods: 1. Four-wheel method: When the ramp angle is not too steep, generally use all four wheels to descend. The torso should lean backward, and both hands should lightly grip the handrims, applying even resistance to slow the wheelchair's descent and ensure a controlled slide down; 2. Front-wheel lift method: Lift the front wheels and slowly push the handrims forward while applying even resistance with both hands to maintain balance, descending only on the large wheels.
