The present invention relates to a fire door assembly, a fire door, and a door frame, and more particularly, a fire door for maintaining radiant heat and conduction heat of 400 ° C. to 600 ° C. due to fire below the boiling point of liquid injected into the fire door and the frame. An assembly and a fire door and a door frame.

In general, the fire door assembly is a fire door (100) to block the transition of flame into the room in the event of fire, as shown in Figure 5, the fire door 100 so that the fire door is rotatably coupled to the doorway of the room. 100 is composed of a door frame 200 which is hinged. The fire door 100 is formed by laminating the internal laminated material 102 such as fire brick and glass fiber in the plate-shaped body 101, the door frame 200 is a hollow frame body 201 hollow inside It is composed of

In the past, a fire door in which a refractory brick is inherently heavy has a problem of carrying a heavy weight, and in case of a fire, the flame heats the refractory brick in the fire door so that heat at the same temperature as the fire site is transferred to the opposite side to block the fire. There is a problem that can not be. In addition, the fire doors in which the glass fibers are embedded are gradually lowered to the lower side as the glass fiber, which is an internal filling material of the fire door, breaks down due to an impact generated while opening and closing the fire door, so that an empty space is generated on the upper side of the fire door. There is a problem that the fire protection function is lost on the upper side of the fire door in case of fire due to the empty space.

In addition, the fire door and the door frame does not block the radiant heat or conduction heat generated by the flame even if the flame of the outer side is blocked, there is a problem that the high heat is conducted to the inside of the fire door, the fire is easily transferred to the interior side.

In addition, the high heat conducted to the fire door and the door frame has remained a major factor in regenerating the fire even after extinguishing the fire.

Accordingly, the present invention has been made to solve the conventional problems as described above, the object of the present invention is that the entire insulation door is not uniformly changed by the external impact generated when the fire door is opened and closed, More than 90% of the radiant heat and conduction heat injected into the fire door are kept below the boiling point of the mixed liquid composed of water to prevent the fire from being transferred to the opposite side of the fire site.

In addition, another object of the present invention is to prevent deformation of the fire door and the door frame by the hydraulic pressure of the non-combustible liquid filled in the hollow portion.

In addition, another object of the present invention is to prevent freezing and corrosion of the fire door and door frame due to the non-combustible liquid.

Figure 3 is a partially enlarged side cross-sectional view showing a state of use of the present invention.

As shown in the drawing, when a fire occurs outside the fire door 1 in a state in which the fire door 1 is closed and closed in the door frame 2, heat due to the fire causes the plate body 11 and the frame body. The non-combustible liquids 12 and 22 filled in the hollow portions 111 and 211 in the inner side thereof are heated while being conducted at the outer surface of the 21.

As such, when the non-combustible liquids 12 and 22 are heated, heat is vaporized to take away the heat conducted by the flame, thereby preventing the transfer of flame and heat to the inside of the fire door 1 and the door frame 2.

At this time, as the non-combustible liquids 12 and 22 are evaporated by the flame, the pressure rises inside the hollow portions 111 and 211. When the pressure is equal to or higher than a predetermined pressure, the check valves 16 and 26 are increased. The hollow parts 111 and 211 are opened while the pressure is balanced with atmospheric pressure.

In addition, the user can check the temperature of the non-combustible liquids 12 and 22 filled in the hollow portions 111 and 211 through the thermometers 18 and 28 inside the fire door 1 and the door frame 2. By grasping, it is possible to grasp the degree of flame on the outside.

Figure 4 is a front sectional view showing another embodiment of the present invention.

As shown therein, the fire door assembly includes at least one reinforcing rib 15 and 25 attached to the inside of the hollow portion 111 and 211 of the plate body 11 and the frame 21, and the reinforcing rib. Communication portions 151 and 251 are formed on the reinforcing ribs 15 and 25 so that the non-combustible liquids 12 and 22 flow through the 15 and 25.

The reinforcing ribs 15 and 25 are installed in the hollow body 111 and 211 of the plate body 11 and the frame body 21 and the plate body 11 due to the water pressure of the incombustible liquids 12 and 22. ) And the frame 21 to prevent deformation.

In addition, the communicating portions 151 and 251 formed on the reinforcing ribs 15 and 25 communicate with each other without the inside of the hollow portions 111 and 211 being closed by the reinforcing ribs 15 and 25. In order to fill and discharge the non-combustible liquid 12, 22 to be made more smoothly.

As described above, the present invention maintains the thermal insulation for a long time without changing the thermal insulation by the external impact generated during opening and closing of the fire door, and at the same time, the radiant heat and conduction heat as well as the flame caused by the fire are uniformly blocked as a whole, so that the spread of the fire is smoothly performed. It is possible to maintain the door assembly on the opposite side where a fire occurs on the opposite side for a long time below a certain temperature and to prevent the recurrence of fire due to the heating of the fire door or the door frame itself.

In addition, the present invention by the evaporation of the non-combustible liquid in the fire to smoothly eliminate the increase in the internal pressure of the fire door and the door frame, it is possible to prevent damage due to the increase in the internal pressure of the fire door and the door frame.

In addition, the present invention has the effect that the repair and management work due to freezing and corrosion of the fire door and door frame due to the non-combustible liquid.
