Description

Booth for securing a prefabricated fire evacuation space {ASSEMBLY FIRE SHELTER}

The present invention relates to a booth for securing a prefabricated fire evacuation space, and more particularly, by bringing a plurality of structures to the secured space without changing the structure of the existing building and assembling it, the left and right wall surfaces and the rear side of the prepared space It relates to a booth for securing a prefabricated fire evacuation space, which forms the wall, ceiling and floor, and each structure has heat insulation for a significant amount of time, and the ability and performance to block harmful gases.

In general, when a fire occurs, a fire alarm sounds, a sprinkler installed on the ceiling is activated, and people at the fire site must evacuate quickly to avoid casualties. However, in reality, there are many buildings that do not have fire suppression or suppression environment, and in the case of apartments, it is more urgent to secure an evacuation space.

And in the case of high-rise buildings, the length of the passages connected to the ground is relatively long, so it takes a lot of time to evacuate to the ground in case of a fire. In many cases, serious casualties are caused.

Therefore, recently, legislation requiring high-rise buildings to be equipped with fire evacuation facilities has been prepared. Fire evacuation facilities suitable for this have not been developed.

Accordingly, the Ministry of Land, Infrastructure and Transport made it compulsory to secure an evacuation space on the balcony of an apartment building through the revision (enforced on April 4, 2016) in the relevant laws, namely, on April 6, 2015, 「Rules on Standards for Evacuation and Fire Protection Structures for Buildings」. If you look at the contents, it is necessary to secure an evacuation space on the balcony and block the entrance with a 'first-class fire door' to reduce the casualties caused by the rise in internal temperature and inhalation of harmful gases in the event of a fire. The first-class fire door must be able to secure the performance of over 1 hour of non-heating and 30 minutes of blocking of heat.

In this way, the apartment must have a fire escape space in the future, and the key here is to have the heat shielding ability and performance not only on the entrance side of the preparation space, but also on the left and right walls, the rear wall, the ceiling and the floor, without changing the structure of the building. Installation should be done simply.
