Description
The present invention relates to a fire door, and more particularly, to a fire door having a heat transfer minimizing function for minimizing the heat transfer between the front panel and the back panel of the external panel to minimize damage due to heat transfer when a fire occurs .
Generally, a fire door is installed between a cabin, a cabin, a vehicle, and a structure of a ship or a railway vehicle to prevent the fire from spreading when a fire occurs.
Such a fire door is made of metal and the outer panel is made of various materials to minimize the propagation of the flame.
However, since the conventional fire door is formed so that the front panel and the back panel of the outer panel are connected to each other to enclose the inner heat insulator, the heat is quickly conducted to the entire front panel and the back panel of the outer panel located outside the room or outside, There is a problem that the door is opened or the door can not be opened when the door is opened for escape.
In addition, since the front panel and the back panel are connected to each other, it is impossible to prevent thermal deformation of the outer panel due to fire, so that the structural load such as the expansion and pressure of the outer panel due to heat deformation is directly transmitted to the inner insulating material, It causes not only damage but also damages such as bowing or swelling of the fire door.
Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a heat conduction minimizing function that minimizes thermal conduction by using a front plate, a back plate, To provide a fire door.
In order to accomplish the above object, the present invention provides a fire door, which is resistant to damage and deformation in a fire, reduces ductility and strengthens fire resistance by using metal materials such as mild steel or aluminum, An outer panel; A pair of first insulation sheets formed on one side of the inner sides of the front plate and the back plate and a second insulation sheet formed between the first insulation sheets to block or minimize conduction of heat; An inner frame provided inside the outer panel to improve strength and to form an empty space to minimize weight; .
And one end of the front plate and the back plate of the outer panel are separated from each other without being connected to each other, thereby forming a heat-transfer preventing space.
And a coating layer of a flame retardant film or a flame retardant material is formed on the surface of the outer panel to improve strength and quality.
The second insulating sheet is formed of a foamed thermal insulator so as to fill a space that may occur between the first insulating sheet and the front and rear plates when the temperature of the second insulating sheet is higher than a predetermined temperature and to block or minimize heat conduction.
The outer panel forms a heat-transfer-preventing space, so that the air expanded at a high temperature inside the fire door can be smoothly discharged when a fire occurs.
As described above, the present invention prevents or minimizes the heat conduction to the front panel and the back panel of the outer panel through the heat-transfer prevention space that blocks or minimizes the movement of the heat, so that the door is opened for fire suppression, lifesaving, There is an effect that the image can be prevented from being opened.
It is another object of the present invention to prevent thermal deformation of an outer panel and to prevent a structural load such as expansion and pressure of an outer panel from being directly transmitted to an inner insulating material to improve heat insulation and to prevent damage such as warping or swelling It is effective.
