Description

FIRE DOOR FOR ENTRANCE AND SHELTER}

The present invention relates to a fire door for a front door and a shelter, and more particularly, to a fire door for a front door and a shelter designed to be implemented to prevent distortion of the fire door without installing an additional reinforcement bracket.

Recently, as the number of cases of human damage caused by fires in buildings has increased, interest in ways to reduce the spread of fires in buildings and to secure the stability of evacuation is increasing. As fire protection devices for buildings, there are fire shutters, fire doors, top-down evacuation doors, etc. In particular, fire doors, which are mainly installed in the staircase section of buildings, the corridor or hoistway sections of multi-storey apartment houses, or the fire floors, are usually installed in the fire. And because it prevents the spread of smoke, it is the most important factor for evacuation or evacuation.

The fire door is made of a non-flammable flame-retardant material such as a steel sheet, and a material having a low heat transfer coefficient, for example, polyurethane foam, is installed inside. In the event of a fire, the room temperature increases due to fire and flame, but conventional steel sheet fire doors are simply filled with insulation to lower the heat transfer coefficient inside both steel plates forming the exterior, so they come into contact with high temperatures or come into contact with flames. If it does, deformation such as expansion or torsion may occur in the door body due to heat and gas pressure. Due to the expansion, thermal deformation, and torsion, a gap may occur between the door and the hinge-side door frame to which the hinge is coupled, and harmful gas, fire, and flame may be introduced through the gap, thereby increasing human damage.

The conventional fire door as described above has a problem that the front door is warped due to the use of a thin plate. In order to reinforce this, the reinforcement bracket was mounted on the front door by welding or riveting to prevent warping, thereby increasing manufacturing costs and increasing manufacturing costs.

In addition, when a heat insulating material (Glass Wool, mineral wool) is used for a long time between the front plate and the rear plate, the performance of the heat insulating and fire-retardant functions may deteriorate due to sag in the downward direction of the door. Due to the deterioration of the performance of the heat insulation and fire protection functions, the insulation needs to be replaced, and the front and back plates are fixed to each other by rivets, etc., and there is a inconvenience in that the entire fire door needs to be separated for replacement.

In the related art, since the reinforcing material has to be welded, a hassle occurs that the coating process must be separately performed after production of the product.

On the other hand, the above-mentioned background technology is the technical information acquired by the inventor for the derivation of the present invention or acquired in the derivation process of the present invention, and is not necessarily a known technology disclosed to the general public before filing the present invention. .
