Abstract

FIELD OF THE INVENTION [0001] The present invention relates to a fire door interconnection structure, comprising: a fire door including two front and rear sides facing each other and two sides connecting both ends of the front and rear sides; A first surface and a second surface facing each other on the side surface of the fire door and vertically protruding from the first surface and the second surface, respectively, and a third surface and a fourth surface facing a part of the front surface of the fire door, Each frame having a first and a second protruding end; A first packing attached on a first side of the frame; A second packing attached on a fourth side of the frame; And one or more hinges joining the fire door in a first surface direction of the frame, wherein the fire door is tilted backward in a backward direction.

Description

Fire door assembly

The present invention relates to a fire door assembly, and more particularly, to a fire door assembly including a fire door and a frame to which the fire door is coupled and a buffer packing interposed therebetween To a fire door assembly.

Generally, a fire door is a structure such as a doorway door or an emergency door which is installed in a house, an apartment, a factory, an office, a prefabricated building or the like to prevent the fire from spreading to the back side. A typical fire door joining structure is shown in Fig.

This is because the frame 20 is a rectangular door frame installed through the wall and one side of the frame 20 is engaged with the frame 20 by a coupling means such as one or more hinges 40a and 40b, A handle 30 is provided on the front and back surfaces of the fire door 10 so that the user can hold the handle 30 to open or close the fire door 10. [

At this time, either the front surface or the rear surface of the fire door 10 has a locking protrusion 16 protruding along one edge so as to cover a space between the door 20 and the adjacent frame 20 when the fire door 10 is closed In the event of a fire,

So that the fire door 10 can be turned only in one direction,

As the material of the fire door 10, a metal material having high heat resistance and mechanical strength is usually used

Referring to FIG. 2, which is a cross-sectional view taken along line II-II of FIG. 1, the fire door coupling structure 1 will be described in more detail.

In the fire door 10, the surface to which the reference numeral 12a is applied is referred to as the front surface,

, And the frame 20 has an inner surface of the fire door 10, that is,

2 is a cross-sectional view taken along the line II-II in FIG. 1, and therefore, the two side surfaces of the fire door 10

It can be seen that only a part corresponding to this is shown.

The fire door 10 includes first and second side surfaces 14a and 14b connecting the front surface 12a and the rear surface 12b and the front surface 12a and the rear surface 12b,

And this fire door 10 is provided with the above-mentioned two side surfaces 14a, 14b and

Are positioned between the frames 20, each of which includes opposing first and second surfaces 22a, 22b.

The first surface 22a and the second surface 22b of the frame 20 protrude from the rear surface 12b of the fire door 10 to enter the inside of the rear surface 12b of the fire door 10, The first and second protrusions 24a and 24b protrude along the edge of the front surface 12a of the fire door 10 and protrude from the frame 20, It is possible to prevent smoke and heat from being transmitted to the back surface of the fire door 10 when the fire is generated. And the other edge portion of the frame

The hinge 40 is provided with a connecting means such as a hinge 40 for connecting the door 20 to the door 10 so that the door 10 can be opened and closed with a fan shape. 2, which shows a section cut along the line

But it is shown for convenience of explanation.

As the hinge 40, various members such as a hinge or a door damper may be used

However, all of the functions thereof are such that one side of the fire door 10 is fixed to the frame 20 so that the fire door 10 can be opened and closed with the fire door 10 centered thereon.

The fire door 10 whose one edge is coupled to the frame 20 by means of a coupling means such as a hinge 40 is positioned at a position where the latching jaw 16 of the fire door 10 and the first The first and second protruding ends 24a and 24b of the frame 20 are normally opened only in the front surface 12a without being opened in the rear surface 12b direction by the first and second protruding ends 24a and 24b. The first and second packings 50a and 50b made of a rubber material are interposed between the rear surface 12b and the rear surface 12b of the fire door.

However, the conventional fire door connection structure 1 having the above-described construction has some problems in its use. This is because the fire door 10 and the frame 20 are separated from each other, so that the soundproof and windproof functions are deteriorated, 10, the noise generated due to the collision between the door 10 and the frame 20 is a problem.

That is, between the frame 20 and the rear surface 12b of the fire door 10, the space between the normal fire door 10 and the frame 20 is filled, The second packing 50a and the second packing 50b are interposed between the door frame 20 and the door frame 10. The portion of the door frame 20 which collides with the door 20 when the fire door 10 is opened and closed, And the first face 22a of the frame 20 and the corresponding fire door 10

The first and second packings 50a and 50b interposed between the rear face 12b of the normal fire door 10 and the first and second projecting ends 24a and 24b of the frame 20 are the first side face 14a. The impact noise between the fire door 10 and the frame 20 is not significantly reduced and the effects of soundproofing and windshield are hard to be expected even when the specifications of the packings 50a and 50b are not accurate .

Further, since these first and second packings 50a and 50b are formed as a bond on the frame 20,

It is frequently observed that the construction time is long and easily detached even in a small impact, which causes various limitations on the use of the fire door.

In a frame comprising a second overhang, first and second packings are respectively attached on the first and fourth sides of the frame to provide a more improved room and windshield function
