Is the wind shaft an elevator shaft?

The air shaft is not an elevator shaft. The air shaft is usually set up next to the elevator shaft. Depending on the design, the air shaft also has different functions. Generally speaking, the air shaft has a certain amount of noise. If you want to buy If the house is close to an air shaft, sound insulation must be planned during decoration.

What types of air shafts are there

1. Smoke exhaust shafts: Except for high-rise residential buildings, smoke exhaust shafts must be installed in high-rise public buildings if natural ventilation is not possible. Wells and smoke exhaust wells should generally be aligned up and down. The area of ??the smoke exhaust well should be considered as follows: a) For smoke exhaust in the corridors of office and hotel buildings, a well of about 0.0.7 square meters is required; b) For smoke exhaust in commercial buildings, the smoke exhaust The well needs about 1.5 square meters; c) For smoke exhaust in underground garages, the area of ??the smoke exhaust well is about 2‰ of the area of ??the smoke exhaust area. More than one well can be shared, and the area of ??the shared well is based on the maximum value.

2. Air supply shaft: For places with mechanical smoke exhaust, if there are no windows, doors (excluding fire doors), driveways, etc. that are directly connected to the outdoors, an air supply shaft must be installed on the second underground floor. The garage must be equipped with an air supply well, and the area of ??the air supply well is equal to twice the area of ??the smoke exhaust well serving this area.

3. Positive pressure air supply shafts: For stairwells, elevator front rooms, etc., positive pressure air supply shafts need to be set up in accordance with specifications. The positive pressure air supply shafts in stairwells are generally not less than 1.2 square meters. The positive pressure air supply shaft in the room is generally not less than 0.8 square meters. It should be noted that the basement stairwell and the above-ground stairwell are completely separated by fire doors, so the positive pressure air supply shaft in the basement stairwell It needs to be considered separately. According to the decoration regulations in Shanghai, there should be no more than three floors underground, and the height difference between the lowest underground floor and the outdoor entrance and exit should not be greater than 10 meters. The first floor has a door that opens directly to the outside or there is no door that opens directly to the outside. If the openable exterior window is less than 1.2 square meters, it is not necessary to install a positive pressure air supply system. If the above conditions cannot be met, a positive pressure air supply shaft of not less than 1.2 square meters must be installed. At this time, if the positive pressure air supply fan can only be placed On the top floor, the positive pressure air supply shaft in the stairwell must be at least 1.8 square meters.

4. Fresh air shafts: In high-rise public buildings, if fresh air cannot be taken in on each floor, fresh air shafts need to be set up. The area of ??the fresh air shafts is related to the area of ??the service area. For office and hotel buildings, the ratio is about For commercial buildings, the ratio is about 1/1,000. If the new air shaft serves multiple areas, the areas should be added up.

5. Exhaust shaft: In high-rise condominium buildings, if exhaust gas cannot be discharged horizontally on each floor (including exhaust from toilets, tea rooms, and smoking rooms), an exhaust shaft is required. The area is approximately 80% of the fresh air shaft area.
