Description

Deformation prevention device of fire door

The present invention relates to an apparatus for preventing deformation of a fire door, and more particularly, to a fire door deformation preventing apparatus capable of effectively preventing a fire door from being bent by a flame during a fire.

In general, fire accidents caused by fire in a fire are not only directly affected by the flame of the place where the fire occurs, but also indirectly caused by the smoke spreading into the building.

Here, flames and smoke are a major cause of human casualties, which can be said to occur when a large number of victims come out of a fire in a building.

Particularly, smoke is diluted by air and the risk is lower than that of flame or gas immediately after burning. However, the fundamental reason why smoke acts as a very dangerous factor in human accidents is that the rate of diffusion in the building is very fast Because.

Accordingly, a fire door is installed in the building in order to prevent the flame from moving to another space during the fire to expand the fire area or to prevent the smoke generated by the fire from entering or diffusing into other areas.

However, when a fire occurs, the fire door is heated by the heat, and as the fire door starts to deform, a gap is created. There is a problem that the flame escapes from the gaps formed due to the deformation of the fire door so that the fire is transferred to another place and is ignited.

In order to solve this problem, a reinforcing piece is formed on the rear side of the fire door so that it can be caught by the jaw when the door is inserted into the recess of the door frame member in the fire door (registration number: 20-0251262) Although the fire door has been deformed by the heat in case of fire, it has been proposed to prevent the fire from spreading to other places by preventing the door from being separated from the door frame member. However, it is not enough to completely prevent the fire door from bending.

Therefore, there is an urgent need to develop a technology that can prevent the fire door from bending due to flame during a fire.
