There is a "way" to make money, and if you are not careful, it may lead to trouble, and the wrong brother's business experience is clever and used in the wrong place.
The wrong brother stopped the electric bicycles in the community, claiming to have found a charging place that was cheap and close to home.
Let's take a look, the charging place in the mouth of the wrong brother turned out to be an overhead layer.
The wrong brother hit the muzzle again, and the place that the wrong brother was looking for did not meet the requirements for parking and charging of electric bicycles, so the question is, under what circumstances can electric bicycles be parked and charged in the overhead layer.
The overhead level is connected to the public foyer, evacuation walkway, stairwell or safety exit, and the electric vehicle cannot be parked or charged without complete fire separation.
The overhead floor is designed to park or charge electric vehicles, and the evacuation stairs and safety exits of residential buildings are separated by solid walls, so that electric vehicles can be parked or charged under the condition that safety conditions are met.
What is an "overhead layer"? Can I park an e-bike on the overhead level of the building? What are the fire safety requirements for parking and charging in the overhead layer of the building, let's learn together.
What is a "Building Overhead Layer"?
According to the "Unified Standard for Civil Building Design" (GB50352-2019), the overhead layer is an open space supported by a structure and without a perimeter retaining wall, specifically referring to the building space formed by the deep foundation of the building or the overhead part of the sloping building pod without backfilling the soil and stone.
1. Plane setting
1. Electric bicycle parking and charging places are set up in the overhead layer, which should not occupy or block the safety exits and evacuation channels, and should not affect the normal use of building fire protection facilities.
2. The public foyer, evacuation walkway, evacuation stairwell or safety exit of the building should not be led to the outside through the electric bicycle parking and charging place set up on the overhead floor, and the evacuation stairwell should be directly connected to the outdoor on the first floor.
3. When the number of parking spaces in the overhead layer electric bicycle parking and charging place is greater than 200, there should be no less than 2 entrances and exits for personnel and vehicles, and the horizontal distance between the nearest edge of the 2 entrances and exits should not be less than 5 meters.
4. Safety exits, evacuation walkways, stairwells, and foyer areas in the building should take measures to prohibit the parking and charging of electric bicycles, and warning signs should be set up.
5. In addition to electric bicycles, there should be no other flammable and combustible materials that significantly increase the fire load near the electric bicycle charging facilities in the overhead layer, and flammable and combustible liquid pipelines and gas pipelines should not be laid.
2. Group parking
6. The parking and charging places for electric bicycles in the overhead layer should be standardized and orderly, and the number of parking in each group should not exceed 20.
7. E-bike parking spaces should be separated by a separation zone with a distance of not less than 2 meters, or separated by a solid partition wall with a height of not less than 1.5 meters.
8. When setting up the grouping of electric bicycle parking and charging places in the overhead layer, the parking area of each electric bicycle should be reasonably planned to meet the parking needs, and the charging parts should be posted and hung with safety warning signs.
3. Fire separation
9. When the electric bicycle parking and charging place is set up in the overhead layer of the building, the firewall without doors and windows, openings and the floor slab with a fire resistance limit of not less than 1 hour should be adopted, and the lighting and ventilation shaft, public foyer, evacuation walkway, stairwell, safety exit and other parts of the building should be effectively separated from fire.
10. When the overhead layer electric bicycle parking and charging place is separated by fire separation, the overhead area facing the outdoor shall not be closed to meet the needs of ventilation and smoke exhaust.
11. Non-combustible materials should be used for the walls, ceilings, floors and other decoration materials of the overhead layer electric bicycle parking and charging places.
12. When the overhead layer electric bicycle parking and charging place implements fire separation, it shall not affect the normal use of building fire protection facilities, and if necessary, the building fire protection facilities should be adjusted and improved according to the plane layout after separation.
Fourth, fire-fighting facilities and equipment
13. The overhead layer electric bicycle parking and charging place shall be equipped with fire-fighting facilities and equipment in accordance with national and local fire-fighting technical standards, and shall be kept intact and effective.
14. The electric bicycle parking and charging place in the overhead layer should be equipped with a fire extinguisher suitable for fighting Class A, B, C, and E fires, and it should be equipped with a portable water-based fire extinguisher or a cart-type water-based fire extinguisher.
15. The overhead layer electric bicycle parking and charging place should be set up with a video surveillance system in the whole area, and a video surveillance system with flame identification function can be set up if conditions permit, and the video surveillance signal should be uploaded to the fire control room or a manned duty room in real time.
5. Charging facilities
16. The charging equipment for electric bicycles in the overhead layer shall be designed and constructed by professionals, and the electrical products and cables shall be qualified products that meet the current national standards.
17. The charging area should be provided with a special distribution box, the distribution box should be set up in the position with obvious identification and easy to operate, and the distribution box installed outdoors should have fire and insect prevention measures.
18. The overhead layer electric bicycle charging cabinet or charging pile should have the functions of automatic power-off, automatic power-off of charging failure, overload protection, short-circuit protection, leakage protection, charging fault alarm and so on.
19. It is strictly forbidden to pull temporary power lines, sockets and switches to the electric bicycle charging cabinets, battery swapping cabinets or charging piles on the overhead layer. If it is really necessary to carry out line maintenance and transformation, it should be carried out by a qualified electrician.
6. Fire management
20. Territorial township streets and communities (villages) are responsible for organizing and coordinating efforts related to overhead layer electric bicycle parking and charging sites.
21. The building property rights units, user units, management units, residential property service enterprises, and charging facility operation units of the overhead layer electric bicycle parking and charging sites shall clarify the responsibility for fire safety management and be responsible for fire safety management and fire prevention inspections.
22. The building property rights unit, the user unit, the management unit, and the residential property service enterprise shall maintain the fire-fighting facilities and equipment set up on the overhead layer in a timely manner to ensure that they are intact and effective.
23. Guide the construction and operation units of charging facilities to establish a data platform to monitor charging facilities in real time.
24. Building property rights units, user units, management units, residential property service enterprises, and village (resident) committees shall carry out publicity and guidance on the safety of electric bicycle parking and charging in accordance with law, popularize the common sense of initial fire fighting and escape and self-rescue, formulate fire extinguishing and emergency evacuation plans, and include them in daily training and drills.
