Preliminary study on fire causes of building structure Dalian landmark building! How bad is the current situation of external wall

on the 27th, with no casualties.

For the external control high-pressure jet truck, there are many jet blind areas, which is impossible to really stop the fire; The corridor between the two towers is directly baked by the fire at the lower part, which is not only easy to burst into the room, but also the building components of the outer wall will deform rapidly, forming a large number of falling objects, which directly threaten the surrounding personnel and vehicles.

When the temperature reaches, a wall will be involved in the combustion instantly; Second, there are no fire-fighting facilities on the outer wall.

In addition, there is a risk of setting up a position under the building.

that day, a fire broke out in a market in Dalian, with heavy smoke and fierce fire, and the subway station was temporarily closed.

The fire fighting lasted more than 7 hours, which was very difficult to put out the fire.

Even if it is not a super high-rise building, the 31 floors are at least more than 90 meters high, which should be classified as a class of high-rise public building.

Special note: the external wall insulation project has lasted for about 30 years, especially from 2000 to 2014, the external wall insulation of a considerable number of buildings does not meet the requirements of the current specifications, and there is a risk of spread of the whole building in case of fire, which needs more attention.

According to official news, the fire was basically extinguished at 23:00 p.m.

Does this mean that the automatic fire alarm system did not act or that although it acted, the attendant in the fire control room did not effectively deal with it? According to the later fire video, the flame enters the building B and burns.

Because the official account official has adjusted the push rules, if you want to continue to receive the contents of the official account, please set the public building number of the building as the star sign, and more points of the “look at” and “praise” in the end of the article.

It is a scarce resource in Dalian.

“If you want to continue to receive the official account, please note that the” WeChat “is a public key.

It was very hard and dangerous.

So, it’s too hard, too pit.

The building covers an area of 63000 square meters.

Before the evacuation of personnel in the building, the flames outside the window were photographed.

If it is a super high-rise apartment building, it is a class of high-rise public building.

The “thermal insulation of the external wall” has become the “fire killer” again, and the accidents are frequent and painful ▼ · at about 9 p.m.

If this notification is true, that is to say, the residents and properties have defects in the initial fire fighting and alarm, which has delayed some time; Secondly, the building was opened in 2008 and put into use in 2009.

The owner went to the property for help.

In this fire, the firefighters went deep into the fire floor and braved the fire and smoke on the top floor to control the spread of the fire.

Personnel evacuation and fire rescue are still in progress.

after the fire, the property owner confirmed the fire and gave an alarm after asking for help and arriving.

The detachment command center immediately dispatched 24 fire stations, 68 fire engines and 366 commanders and fighters to the scene for rescue.

The planning and design of the project is completed by a world-famous design company, and the shape is inspired by the “Arc de Triomphe” of lade fangs, CBD District, France.

Some netizens sighed: this kind of insulation layer is covered with gusset plate, there is a gap between gusset plate and insulation layer, and the fire spread rapidly along the gap, even if there is spraying, it can’t hit the fire point; The fire spread in the lower part of the corridor.

At present, there are 419 households and 818 people living in it.

According to the specifications, automatic fire alarm system, automatic sprinkler system, fire hydrant system, etc.

When the fire has not been completely extinguished, the landmark building is on fire again, and the fire fighting is facing the situation of two-line operation.

The falling of combustibles on the outer wall is easy to cause personal injury and damage to combat vehicles and equipment.

The fire formed three-dimensional combustion.

Beijing News our video product (ID: webvideo) at 16:02 on August 27, 2021, Dalian fire rescue detachment received an alarm that the exterior wall materials of block B of Triumph International in the development zone were on fire.

After the fire, no trapped persons were found and no casualties were found through community telephone contact and fire fighting layer by layer.

Sometimes it takes a few minutes.

When fireworks spread to this part, it is easy to store heat and expand the fire.

Triumph International’s building type is high-rise tower, and the property type is ordinary residence, apartment and commercial residence.

Whether the automatic sprinkler system is started or not has not been officially announced, so further investigation is needed.

Why is it so difficult to put out the fire? After the 19th floor household fire, 127 fire engines and 558 firefighters from five fire brigades were dispatched, and helicopters and 101 meter high fire engines, the highest in China, were dispatched.

Now we have a preliminary understanding of the cause of the fire.

Statistics show that Triumph International is located at the intersection of Jinma road and Heshan West Road, Guobin Road, Jinpu New District, Dalian, close to Jinma road light rail station and only a short distance from the welcome square.

Fires caused by the thermal insulation layer of the external wall or due to the rapid spread of the thermal insulation layer occur almost every year…

For a fire, the speed of plane combustion is relatively slow, but the vertical combustion is not fast.

Why did the fire burn so big? First of all, according to the official news, that afternoon, a household on the 19th floor caught fire.

Are fire fighting facilities functioning? According to the code for fire protection design of buildings, this building has 31 floors.

Liaoning Provincial Fire Rescue Corps mobilized 4 high-rise rescue and fire-fighting formations, 59 fire engines and 192 commanders and fighters from Anshan, Yingkou, Liaoyang and Panjin fire rescue detachment to rush to the scene for reinforcement.

At about 16 p.m.

After it is set up, there is nothing to put out the fire; Third, the fire brigade is facing the adverse situation of large-scale fire fighting and control.

The power supply and gas of the building have been cut off, and the cause of the fire is under investigation.

Triumph International Building is an apartment building.

Another reason to mention is that around 13:00 p.m.

After the property arrived, the room was full of smoke.

On the one hand, it is necessary to organize fire control in the direction of the outer wall, on the other hand, it is necessary to control from the inside to avoid the inward spread of the fire, and on the other hand, it is necessary to search, rescue and evacuate the personnel inside the building, which puts forward high requirements for the dispatch of fire forces, on-site organization, coordination and command.

that day, a household on the 19th floor caught fire.

The owner went to the property for help.

With a total construction area of 63000 square meters, Triumph International is composed of two air connected super high-rise buildings and podium buildings, facing the 360 degree open view of the sea, mountain, port and city of Dalian Bay.

There were no casualties in the accident· At 14:00 on November 15, 2010, a high-rise apartment on Jiaozhou Road, Yuyao Road, Shanghai caught fire.

When the high-pressure jet fire truck is spraying water, the parking and operation area is small, the location is unfavorable, and the water supply intensity is difficult to control the fire in a short time.

By 10:20 on November 19, the fire had killed 58 people..

on December 2, 2019, a fire occurred in the residential area of SR international new town, Hunnan New Area, Shenyang City, Liaoning Province, which was caused by the fire of the thermal insulation materials of the external wall, with a total of 25 buildings on fire, The fire site is the outer wall of the 5th floor and above· On the evening of May 24, 2019, a fire broke out in Jinying shopping center located in Xinjiekou Business District of Nanjing, and the scene was ablaze with fire· On February 1, 2018, a fire broke out in the thermal insulation materials outside the Yuansheng international office building in Greenland, Zhengdong New Area, Zhengzhou, Henan Province· On April 21, 2014, the outer wall insulation layer of yidajiete apartment building in Xinghai Square, Dalian, Liaoning caught fire, and smoke billowed instantly.

Pay tribute to them.

What is the reason for this? First, it burns very fast.

Many retired teachers lived in the apartment.

At that time, the external wall insulation materials of the building may not be incombustible materials, which also led to the spread of fire along the external wall; Third, the building has a corridor at the top.

Since the building fire-fighting facilities are installed inside, there are no fire-fighting facilities on the outer wall.
