Do You Know the Little Knowledge about Blind Way Bricks?

There are many types of bricks, not to mention red bricks, eco-friendly bricks, hollow bricks, clay bricks, shale bricks, coal gangue bricks, fly ash bricks, and sand-lime bricks. Of course, there is one type of brick that you see more often, and that is blind way bricks.

blind way bricks are specially designed tiles for blind people, with a very humane purpose - to prevent blind people from getting lost and falling. However, not all bricks can be blind way bricks, as there are certain standards for their design.

Generally speaking, blind way comes in two forms - one is in the shape of a long strip, and the other is to indicate a stop or a turn. These two forms are different. The long strip shape is called guiding blind way bricks, while the latter is in the form of rounded dots. Both types of blind way protrude about 5mm above the ground. These raised parts can be felt through the cane and the soles of the feet.

Where are blind way set?

In fact, these bricks are set in places such as commercial centers, amusement parks, cultural building entrances, service desks, stairs, bathrooms, medical hospitals, transportation buildings, government agencies, etc. blind way also has a certain width restriction, usually around 0.6 meters. Why? Because this is calculated based on adult average step length of 0.75 meters, net step length of 0.5 meters, and shoe length of 0.25 meters.

When laying blind way, we also need to follow certain rules

For example, the direction and position of the tactile bars should enable disabled people to reach accessible locations smoothly. What if the blind way encounters a building? In this case, guiding bricks and stop bricks need to be set up, with a width not too narrow, no less than 0.6 meters. The thickness below the surface contact points of the blind way can be the same as the thickness of the sidewalk bricks. It should also be noted that trees, guide wires, electrical poles, and other obstacles should not appear in the continuous middle of the blind way. In addition, a guiding blind way should be set at a distance of 250 to 600mm from the square entrance and the sidewalk entrance, with the length and width of the entrance corresponding to each other.

In fact, as early as 1961, the United States formulated accessibility standards for blind way. Since then, blind way has also been established in the capital city of China in 1991, and now blind way can be seen everywhere. China has also issued urban road and building accessibility design specifications, showing that the higher the level of social civilization, the higher the requirements for tactile bars on blind way. The construction of blind way does not seem to be so arbitrary.
