How to distinguish the length and short span of the ramp?

The slope of the ramp is related to the indoor and outdoor height difference of the hotel and the surface treatment method of the ramp.

1. The slope (height/length) of indoor ramps should not be greater than 1:8, the slope of outdoor ramps should not be greater than 1:10, and the slope of ramps used for safe evacuation of children should not be greater than 1:12. . 2. The ramp for wheelchairs should not be larger than 1:12, and the slope in difficult areas should not be larger than 1:8. 3. When the horizontal projection length of the indoor ramp exceeds 15m, a rest platform should be set up. The width of the platform should be based on the function or equipment used. The size depends on the buffer space required.
