Designers should regard this traffic area as a part of the whole traffic system, so sometimes it needs to be increased appropriately.
2. The vertical clear height above the escalator steps should be no less than 2.3m, and the clear height should be along the whole journey of the whole steps and pedals to ensure the safety and smoothness of escalator passengers.
3. The horizontal distance between the center line of the handrail and the wall or obstacle of the adjacent building shall not be less than 500mm under any circumstances, and the distance shall be kept at least 2. 1m above the escalator steps.
If appropriate measures are taken to avoid the danger of injury, the height of 2. 1m can be reduced appropriately.
For parallel or cross-arranged escalators, the distance between the outer edges of the handrails of two adjacent escalators should be greater than 500mm to prevent injuries caused by the movement of adjacent escalators.
4. In the triangle area where the escalator intersects with the floor and at the intersection of the escalator, in addition to meeting the safety distance requirements in the above 3), a vertical anti-collision guard plate without sharp edges should be set above the outer cover plate, and its height should not be less than 0.3m For example, a triangular guard plate without holes should be adopted.
If the distance between the center line of the handrail and any obstacle is greater than or equal to 0.5m, there is no need to use the collision protection plate.
5. At the intersection of the escalator and the upper floor, in order to meet the safety height above the steps and treads mentioned in 2) above, holes with a certain size should be left on the upper floor, and in order to prevent passengers from falling or being scratched, the edge of the perforated floor should have guardrails with a specified height.
Extended data:
The main parameters of the escalator are:
1. Lifting height: generally, it is within 10 meter, and it can reach tens of meters under special circumstances.
2. Tilt angle: generally 30 and 35.
3. Speed: generally 0.5 m/s, and some ladders can reach 0.65 m/s and 0.75 m/s..
4. Step width: 600mm, 800mm, 1000mm.
5. Theoretical transport capacity: According to the speed of 0.5m/s, the transport capacity of asynchronous width is 4,500 people/hour, 6,750 people/hour and 9,000 people/hour respectively.
6, step distance and traction chain pitch, etc.
