Do you need a fire lane for a small high rise on the 11th floor?

Fire lane refers to the road for fire trucks in the event of a fire.

The fire lane shall meet the following requirements.

1) The clear width and clearance height of the fire lane should not be less than meters, and the slope of the open space for the fire truck to stay should not be greater than 3%.

2) At least two places in the circular fire lane should be connected with other lanes.

3) The end of the fire lane should be set up with a return lane or a return yard, the area of the return yard should not be less than 12mx12m, for high-rise buildings, should not be less than 15mx15m; The area of the return yard for large fire trucks should not be less than 18 18 square meters.

4) The pipes and culverts on the fire lane should be able to withstand the pressure of large fire trucks.

5) When the fire lane passes through the door opening of the building, its clear height and net width should not be less than 4 meters; The net width between the door stacks should not be less than meters.

6) Annular fire lanes should be set around high-rise buildings, and fire lanes can be set up along the two long sides of the building when it is difficult to set up annular fire lanes.

Absolutely. 1. Regarding the spacing and height (width), Article 1 of the Code for Fire Protection Design of High-rise Civil Buildings (GB50045-95) clearly states that the width of the fire lane should not be less than 4 meters, the fire lane should be greater than 5 meters from the outer wall of high-rise buildings, and there should be no obstacles within 4 meters above the fire lane;

2. Turning radius: The provisions of Article 1 of the Code for Fire Protection Design of High-rise Civil Buildings (GB50045-95) explain: the minimum turning radius of the curved arm climbing fire truck is 12 meters. Therefore, the turning radius is 9 meters, which is obviously smaller;

3. Circular lane: Around high-rise buildings, circular fire lanes should be set up. Article 1 of the Code for Fire Protection Design of High-rise Civil Buildings (GB50045-95).

The entrance doors of the eleventh small high-rise buildings are all Grade A fire doors, and the staircase entrances are generally wooden fire doors.

There must be an emergency fire escape, and there must be a fire door when there is a passage.

Hello, 51 Anju is at your service.

Yes, regarding the installation of fire doors, simply put, as long as the entrance door is facing the elevator front room (vertical or horizontal buffer space between the elevator and the entrance door), or facing the open staircase, fire escape, etc., fire doors must be installed. In addition, for units with 11 storeys and below, fire doors are required to open to the stairwells. If there are 18 floors or less, the entrance door must also be equipped with a fire door. If the door of the house must be opened to the front room, the door must also be equipped with a fire door.

If you have any questions, please feel free to ask 51 Habitat.

Multi-storey buildings require ring fire trucks. The three-story office building must also be made into a circular passage.

It is mainly based on the following provisions of the Code for Fire Protection Design of Buildings:

When the length of the street part of the building is greater than 150m or the total length is greater than 220m, a circular lane should be set up; Or your short side is more than 24m, which actually refers to the thickness of the floor. There should be a fire lane that can enter the inner courtyard, and if you can't get in, a fire lane is required on the back.

Around high-rise buildings, there should be a circular fire lane. When it is difficult to set up a circular lane, a fire lane can be set along the two long sides of the high-rise building, and when the length along the street of the building exceeds 150m or the total length exceeds 220m, a fire lane through the building should be set up at a moderate position.

The "Code for Fire Protection Design of Buildings" has no requirements for the fire climbing surface, and the "Code for Fire Protection Design of Buildings" is implemented for small high-rise buildings, so it is not required. However, from the perspective of practical needs, the following aspects should be considered: 1In order to ensure that firefighters enter the high-rise building from the stairwell, reach the fire floor as soon as possible, and carry out fire extinguishing and rescue, there must be a staircase leading to the outside or an exit leading to the stairwell.

2.A large area of curtain wall glass should not be set on the ascending surface to prevent the adverse impact of curtain wall bursting on the normal ascending operation.

3.Each floor of the ascending surface must be provided with doors, windows or openings that can provide firefighters with access to the interior of the building through the ascending vehicle.

4.The roof evacuation platform and refuge floor must be consistent with the ascending surface to ensure that the ascending vehicle rescues the personnel in the roof evacuation platform and refuge floor in a timely manner.

5.Avoid setting up large billboards on the ascending surface.

6.The setback façade can be allowed as the ascending surface, but the relationship between the setback width and the floor height should be well handled. For this reason, the setback width of each floor should not be greater than n times the height of the building, and the coefficient n should be determined according to the maximum inclination angle of different climbing vehicles in different cities.

This contradiction is one of the contradictions between the current "Construction Regulations" and the "High Regulations". That is, the way the top level is defined. Personal opinion:

Purely from the perspective of evacuation, rescue, and fire extinguishing, then the height is the main basis for dividing the upper floors. Therefore, the climbing surface should be considered purely from the perspective of building height!

Generally not, but it can also be considered.

This independent enclosed evacuation staircase needs to be set up with a fire door, and the area of each floor without a fire door does not exceed the allowable 850 square meters, mainly according to the design requirements, and the staircase area needs to be superimposed and calculated.

There should be fire doors. Used to enclose stairwells.

Yes, otherwise how to solve the fire problem.

It must be installed at a height of more than 33 meters.

Now the elevator itself has a fire-fighting function

If needed, the 12th floor is already a high-rise, according to the "Code for Fire Protection Design of High-rise Civil Buildings" [GB50045-95], around the high-rise building, a circular fire lane should be set up. When it is difficult to set up a circular lane, a fire lane can be set along the two long sides of the high-rise building.

1. It is indeed necessary to set up, and the detailed setting method is shown in Chapter 6 of the "Code for Fire Protection Design of Buildings".

2. The difference should lie in whether there is a circular fire lane, and some multi-storey buildings only need to set up a fire lane along one side.

Fire lanes should be set up in low- and middle-rise elementary school buildings.

No matter what the building, it needs to be equipped with a fire lane.
