Abstract
The present invention relates to a door frame (100) having an opening formed therein; A door main body 200 hinged to the door frame 100 and having a hollow portion 210 therein; A first sealing frame 300 inserted into the hollow portion 210 such that the upper end of the first sealing frame 300 is partially exposed; A second closing frame 400 inserted under the hollow part 210 such that a lower end of the second closing frame 400 is partially exposed; And a pressing member which is installed between the first closing frame 300 and the second closing frame 400 and which presses the first closing frame 300 upward and presses the second closing frame 400 downward, The first and second sealing frames 300 and 400 may be attached to the presser body 500 when the door body 200 is inserted into the opening of the door frame 100. [ And the door 100 is pressed by the door frame 100 to automatically seal the gap between the door body 200 and the door frame 100. [
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire door provided in an opening of a building to prevent expansion and combustion of fire.
Generally, a fire door serves to prevent the intrusion or diffusion of smoke and heat when a fire occurs. Particularly, the fire door is installed in the entrance of the apartment house or the entrance of the building office.
However, there is a gap between the fire door and the door frame from the time of construction, and when the fire door is bent or twisted due to aging, a clear space is formed between the fire door and the door frame or uneven spaces are generated. And toxic gas can easily enter into the room, which threatens safety, has a poor soundproofing ability, can easily transmit internal or external noise, and has a problem of inflow and outflow of air, resulting in loss of cooling and heating energy.
In order to solve these problems, adhesive tapes using various materials such as sponge, foamed rubber, silicone rubber and the like are installed in the gaps between the fire doors and the door frame. However, such adhesive tapes suffer from problems .
Therefore, it is necessary to develop various fire doors to solve the above-mentioned problems.
A related art is a structure of a fire door used in a door frame in which a first contact surface and a second contact surface are sequentially downwardly stepped in the Korean Patent Laid-Open Publication No. 2011-0117869, wherein a cross- And an end portion of a vertical end extending from the outer close contact surface is bent in a semicircular shape to form a fitting bend portion, and the end portion extending to the fitting bend portion And an outer guide end for bending and bending outward to form an outer engaging jaw. The cross-shaped four ends, which are equally cut at four corners, are bent in a semicircular shape inserted into the fitting bending portion to form an insertion bending portion And an inner side portion that bends outwardly from the insertion bending portion and the extending end to form an inner engagement jaw to be engaged with the insertion jaw And the door frame is closed by engaging the insertion bending portion of the inner panel with the fitting bending portion of the outer panel so as to close the door frame.
SUMMARY OF THE INVENTION The present invention has been conceived in order to solve the above-mentioned problems, and it is an object of the present invention to provide a door structure in which a component installed for sealing is externally impacted, To prevent a fire door from being opened.
Another object of the present invention is to provide a fire door which can prevent a user from falling down due to a foot on the door frame in the process of passing through the door frame, will be.
The fire door (1000) according to the present invention includes a door frame (100) having an opening formed therein; A door

The
Accordingly, when the door body according to the present invention is inserted into the opening of the door frame, the first and second closing frames are brought into close contact with the door frame by the pressing body to automatically seal the gap between the door body and the door frame The first sealing frame and the second sealing frame provided for sealing between the fire door and the door frame are brought into close contact with the door frame by the pressing body even when an external impact is applied to prevent gaps between the fire door and the door frame .
Further, the fire door according to the present invention is advantageous in that the floor is not formed in the door frame so that the user can prevent the user from tipping over the door frame in the process of passing through the door frame, and the freight movement using the carrier or the car is convenient.
