In some cities, this “renewal” holiday has been extended.
The boat reminds everyone: when staying at home, in addition to giving consideration to learning and virus protection, you should also pay attention to your weight.
Oh ~ roar ~ well, to get down to business, the fire separation component is the main building component for the division of fire zones of buildings, It is an important part in the fire test.
Today, Mr.
Jiao summarized the main test points of fire separation components for you.
The crew come to pick up the order ~ summary of knowledge points | Click to enlarge the picture | exercise part 1 According to the current national standard code for fire protection design of buildings gb50016, the following practices meet the requirements is ().
A.
The fire resistance limit of the firewall in a vinyl acetate plant is 3.0hb The annoyance limit of the firewall in the grinding workshop of a flour mill is 3.0hc The fire resistance limit of the firewall in a medical protective clothing production workshop is 3.0hd The fire resistance limit of the firewall of a rice warehouse is 3.0h [click the blank space below to see the answer] [analysis] C, option a is class a plant, option B is class B plant, option C is class C plant and option D is class C warehouse.
The fire endurance of firewalls in class A and class B plants and class A, class B and class C warehouses shall not be less than 4.00h.
The fire resistance limit of firewall in other parts shall not be less than 3.00h.
Therefore, only option C in this question meets the requirements, and choose C in this question.
2.
According to the current national standard code for fire protection design of buildings gb50016, the following practices do not meet the requirements ().
A.
The fire resistance limit of the floor of a comprehensive building with a building height of 110m is 2.0hb A residential building with a building height of 60m and a commercial service network on the first floor has a floor fire resistance limit of 1.5hc The fire control room on the first floor of a hospital outpatient building is separated from other parts by a fire partition with a fire resistance limit of 2.50h and a floor slab with a fire resistance limit of 1.50h.
D.
a commercial building with a building height of 52m is equipped with a roof parking lot, and the fire resistance limit of the floor slab of the building is 1.5h [click the blank space below to see the answer] [analysis] d, According to Article 5.1.4 of code for fire protection design of buildings gb50016-2014 (2018 Edition), the fire resistance limit of the floor of civil buildings with a building height greater than 100m shall not be less than 2.00h.
Option a meets the requirements; 5.4.11 for residential buildings with commercial service outlets, the residential part and commercial service outlets shall be completely separated by fire partition walls with fire resistance limit of not less than 2.00h and without doors, windows and openings and 1.50h non combustible floors.
The emergency exits and evacuation stairs of residential part and commercial service outlets shall be set separately.
Option B meets the requirements; 6.2.7 the fire control room, fire extinguishing equipment room, fire pump room, ventilation and air conditioning room, power transformation and distribution room, etc.
attached in the building shall be separated from other parts by fire partition with fire resistance limit of not less than 2.00h and floor slab with fire resistance limit of 1.50h.
Option C meets the requirements; According to gb50067-20145.1.6 code for fire protection design of garage, repair garage and parking lot, when the garage and repair garage are built together with other buildings, they shall comply with the following provisions: 2.
The garage (including roof parking lot), repair garage and other parts in the building shall be separated by firewall and non combustible floor slab with fire resistance limit of not less than 2.00h; Option D does not meet the requirements; So choose D.
3.
According to the current national standard code for fire protection design of buildings gb50016, the following statement is incorrect ().
A.
Due to the limitation of conditions, a shopping mall adopts a fireproof rolling shutter with a fire resistance limit of 3.0h for fire compartment separation.
B.
when the fireproof door is set near the building deformation joint, it should be set on the side with fewer floors.
C.
the normally open fireproof door should be able to close automatically in case of fire, It shall also have the function of signal feedback.
D.
the air duct and its thermal insulation materials within 2.0m on both sides of the fire damper shall be made of incombustible materials [click the blank below to see the answer] [analysis] B.
according to 5.3.3 of code for fire protection design of buildings gb50016-2014 (2018 Edition), fire compartments shall be separated by firewall.
When it is really difficult, Fireproof rolling shutter and other fireproof separation facilities can be used for separation.
When the fireproof rolling shutter is used for separation, it shall comply with the provisions of article 6.5.3 of this specification.
6.5.3 when setting the fire shutter at the fire separation part, it shall comply with the following provisions: 3 unless otherwise specified in this specification, the fire resistance limit of the fire shutter shall not be lower than the fire resistance limit of the wall at the part set in this specification.
Option a is correct; 6.5.1 the setting of fire doors shall comply with the following provisions: 1.
Normally open fire doors should be used for fire doors set at places where people often pass in the building.
Normally open fire doors shall be able to close automatically in case of fire, and shall have the function of signal feedback.
5 when it is set near the building deformation joint, the fire door shall be set on the side with more floors, and it shall be ensured that the door leaf does not cross the deformation joint when the fire door is opened.
Option B is wrong and option C is correct; 9.3.13 the setting of fire damper shall comply with the following provisions: 3 the air duct and its thermal insulation materials within 2.0m on both sides of the fire damper shall be made of non combustible materials; Option D is correct; So choose B..
