Description

Fire prevention door and manufacturing method of the fire door

The present invention relates to a fire door and a method of manufacturing the fire door, and more particularly, to improve the fire retardant performance of the fire door, as well as to increase the rigidity of the edge portion (edge portion) more easily by the flame in case of fire. The present invention relates to a fire door and a method for manufacturing the fire door, which can prevent damage and effectively prevent leakage of smoke in a fire by increasing the sealing performance of the fire door.

Conventionally, indoor doors are mostly made of wood or synthetic resin, and indoor doors of such wood or synthetic resin are lost in a short time when a fire occurs, so that the indoor space cannot be protected from flame and smoke for a predetermined time.

Such conventional interior doors do not significantly exceed the 30-minute fire resistance standard of KS-2268-1, which is the performance standard of domestic Euljong fire doors, and in fact, the role of fire protection of an indoor door is meaningless in the event of a fire.

Recently, as the expansion of the balcony of apartment buildings, such as apartments, has become legal, the installation of a separate evacuation space is mandatory, and the performance of the first grade fire door, which specifies that the fire protection performance of the evacuation space and the doors installed inside the room has a fireproof performance at 925 ° C for 1 hour. KS F-2268-1, the standard, was enacted.

Conventional fire doors satisfying the first class fire protection performance are mostly steel fire doors, and some wood fire doors use flame-retardant wood as aggregate and expensive ceramic fireproof board as a filler.

In the case of steel fire doors, there are many problems in applying them to interiors or imparting interior properties. In the case of wood fire doors using flame-retardant wood and ceramic fire boards, the thickness is very thick and the price is high. There is a problem.

Conventional wood fire door is installed in a house or apartment to open and close the door, the front panel, the rear panel, the filling member to be filled in the front, the rear panel, and the edge member bonded to the edge of the door Is made of.

However, in the conventional fire door, since the finishing material is adhered to the edge of the fire door, the edge is very fragile when a fire occurs, so that the fire resistance is greatly degraded, deformed by thermal expansion, and the external fire power is internal. It is easy to penetrate into the house, causing the residents to have an accident without time to escape the fire.

In addition, the conventional airtightness between the fire door and the door frame is low, there is a problem that the smoke leaks in the fire resulting in suffocation due to the smoke.

The present invention not only improves the flame retardant performance of the fire door, but also increases the rigidity of the edge portion (edge portion) so that the edge portion is not easily damaged by the flame in case of fire, and improves the sealing performance of the fire door to increase the leakage of smoke during fire. It is an object of the present invention to provide a fire door and a method of manufacturing the fire door that can effectively prevent the.

Fire door according to an embodiment of the present invention to achieve the above object is a front panel located in the front; A rear panel located at the rear; A non-flammable board positioned at inner sides of the front panel and the rear panel; A first reinforcement member installed at an edge portion and positioned between the front panel and the rear panel and in close contact with both ends of the non-combustible board; First plywood being in close contact with both ends of the first reinforcing material; Second reinforcing members in close contact with both ends of the first plywood; And second plywood in close contact with both ends of the second reinforcing material.

Coupling grooves are formed at both ends of the second plywood, and a gasket is installed in the coupling groove.

Projections are formed at both ends of the non-combustible board, and grooves are formed in the first reinforcement to correspond to the projections.

Fire door according to another embodiment of the present invention comprises a front panel located on the front; A rear panel located at the rear; A first non-combustible board positioned on inner surfaces of the front panel and the rear panel; A second non-combustible board positioned between the first non-combustible board; A first reinforcing member disposed on an edge portion and positioned between the front panel and the rear panel and closely attached to both ends of the first non-burnable board and the second non-burnable board; First plywood being in close contact with both ends of the first reinforcing material; Second reinforcing members in close contact with both ends of the first plywood; And second plywood in close contact with both ends of the second reinforcing material.

In addition, in the method of manufacturing a fire door according to the present invention, the first reinforcing material, the first plywood, the second reinforcing material, and the second plywood are sequentially adhered to both ends of the magnesium oxide non-combustible board, respectively, on the front and rear surfaces of the magnesium oxide non-combustible board. Bond the front and back panels.

As described above, the present invention not only improves the fire retardant performance of the fire door, but also increases the rigidity of the edge part (edge part) so that the edge part is not easily damaged by a fire in case of fire, It is possible to effectively prevent the leakage of smoke.

Hereinafter, a fire door according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.
