DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to the detailed description of the present invention, terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary terms. Therefore, the embodiments described in this specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Therefore, It is to be understood that equivalents and modifications are possible.

Hereinafter, with reference to FIG. 1 to FIG. 3, the construction of a fire door having a double panel adhesive structure according to the present invention will be described.

Referring to an exploded perspective view of a fire door 10 having a double panel adhesive structure according to the present invention shown in Fig. 1, a fire door 10 having a double panel adhesive structure is made of a heat insulating front panel 100, The front panel 100 and the back panel 300 separately manufactured are separately bonded to each other with a double-sided adhesive tape 500a having high adhesive strength.

At this time, the front panel 100 is manufactured to perform heat insulation performance as an important function as a fire door, and the front panel 100 is inserted with the heat insulating member 130 inside the base frame 110. More specifically, as shown in FIGS. 2A and 2B, the front panel 100 is formed as a rectangular panel and has bent portions 111a and 111b protruding from the outer circumferential surface of one side thereof, The heat insulating member 130 having a heat insulating property is inserted and laminated on the hollow portion 113 of the base frame 110 with respect to the base frame 110 provided on the base frame 110. [ The bending portions 111a and 111b protruding from the outer surface of one side of the base frame 110 may include the side bending portion 111a and the up and down bending portion 111b. The bending portion of the base frame 110 may be formed only by the side bending portion 111a.

An aluminum foil sheet 150 is adhered to the bent portions 111a and 111b of the base frame 110 into which the heat insulating member 130 is inserted with a double-sided adhesive tape 500b. At this time, the aluminum foil sheet 150 is attached so as to cover one surface of the base frame 110 from which the heat insulating member 130 is exposed. In FIG. 1, the double-sided adhesive tape 500b is shown to have four double-sided adhesive tapes 500b bonded to the four corner folded portions 111a and 111b of the base frame 110, Alternatively, four or more double-sided adhesive tapes may be used, and a single continuous double-sided adhesive tape may be attached along the bending portions 111a and 111b on the outer circumferential surface. In the present invention, the aluminum foil sheet 150 is preferably attached to the bent portions 111a and 111b of the base frame 110 with a double-sided adhesive tape 500b. In some cases, An adhesive is applied in advance and the aluminum foil sheet 150 may be adhered by the previously applied adhesive so as to cover one side of the base frame 110 from which the heat insulating member 130 is exposed. The aluminum foil sheet 150 is attached to the base frame 110 by the double-sided adhesive tape 500b to cover one surface of the front panel 100 and to cover the back panel 100 with the aluminum foil sheet 150 interposed therebetween 300 is attached to the front panel 100 with the double-sided adhesive tape 500a, the heat insulating property and airtightness of the fire door 10 are increased.

Meanwhile, the rear panel 300 is a panel for taking account of the strength of the fire door, and is hinged to the door frame on which the fire door 10 according to the present invention is installed after being joined to the front panel 100. At this time, the back panel 300 can be formed by combining a flat plate made of a metal material having a predetermined strength and a?

The front door panel 100 and the rear panel door 300 having the double panel adhesive structure according to the present invention are separately manufactured and each of which has a heat insulating property and strength as a fire door, And they are bonded to each other with a tape 500a. The back panel 300 is adhered to the front panel 100 with a double-sided adhesive tape 500a on one surface of the aluminum foil sheet 150 covered with the double-sided adhesive tape 500a. At this time, it is preferable that the adhesive portion between the front panel 100 and the back panel 300 adhered with the double-sided adhesive tape 500a is finished with a fireproof sealant for industrial / architectural use. The side surfaces of the front panel 100 and the back panel 300 bonded to each other by the double-sided adhesive tape 500a are hingedly fixed to the side surface of the door frame on which the fire door 10 is installed. A locking device may be provided after a through hole (not shown) is formed in a portion of the fire door 10 where the side bent portion 111a of the front panel 100 is formed.

Since the front door panel 100 and the rear panel panel 300 are manufactured by joining the front door panel 100 and the rear panel panel 300 with the solid side double-sided adhesive tape 500a in the present invention, It is advantageous that the fire door 10 can be manufactured on the spot by transferring the fire door 10 to a site to be installed.

The front panel 100 and the back panel 300 may be attached to each other in the fire door 10 having the double panel adhesive structure according to the present invention or the base frame 110 and the aluminum foil sheet 150 may be attached to the front panel 100, Sided adhesive tapes 500a and 500b to be attached to each other are preferably double-sided adhesive tapes having a high adhesive strength of 25 to 30 lb / in and a waterproof / moisture proof function. For example, the double-sided adhesive tapes 500a and 500b used for manufacturing the fire door 10 having the double panel adhesive structure according to the present invention are formed of strip type (having the property values of Examples 1 to 3) ) Double-sided adhesive tape may be used.
