What are the design standards for barrier-free access?

(1) Set a ramp to replace the steps at the entrance of all public buildings, and the gradient should not be greater than112. If conditions permit, it is best to set up barrier-free entrances;

(two) set up blind roads in places frequented by the blind, and set up audio facilities at intersections to help the blind identify the direction;

(3) The width of the clearance corridor of the door should be greater than 0.8m. If a revolving door is used, a separate entrance for the disabled should be set up;

(4) The clearance width of all building corridors should be above 1.3m;

(5) Public toilets should be equipped with seat toilets with handrails, and the door partition should be open or push-pull to ensure that the internal space is convenient for wheelchairs to enter;

(6) The clear width of the elevator entrance should be greater than 0.8m. ..

The width of the lower mouth of the fan-shaped unilateral kerb ramp should not be less than1.5m. The width of the upper mouth of the unilateral kerb ramp at the corner of the road should not be less than 2.00M The slope of the unilateral kerb ramp should not be greater than 1: 20.

3. The blind road design shall meet the following requirements

1. The location and direction of blind roads on sidewalks should be convenient for visually impaired people to walk safely and reach barrier-free facilities smoothly.

2. The blind road to guide the disabled should be a strip blind road; Point warning blind roads should be set at the starting point, end point and corner of the blind road. The width of the driving blind lane and the warning blind lane shall be 0.3-0.6m ..

3. The thickness below the tactile part of the blind road surface should be consistent with the sidewalk brick. The tactile strip of the blind road is 0.25mm wide and 5mm high.
