Hereinafter, the present invention will be described with reference to the accompanying drawings. However, the present invention may be embodied in many different forms and therefore is not limited to the embodiments described herein. In the drawings, the same reference numerals are used throughout the specification to refer to the same or like parts.

Throughout the specification, when a part is referred to as being "connected" to another part, it includes not only "directly connected" but also "indirectly connected" . Also, when an element is referred to as "comprising ", it means that it can include other elements, not excluding other elements unless specifically stated otherwise.

1 and 2 are a perspective view and a cross-sectional view, respectively, of a coupling structure of a packing part according to an embodiment of the present invention.

1 and 2, a coupling structure of a packing part according to an aspect of the present invention includes a plurality of through holes 110 formed in at least one side 100 of a door frame and a door; And a sealing part (220) for sealing between the door and the door frame when closed, and a connecting part (230) for connecting the closing part and the closing part, (200), and an adhesive layer (300) may be interposed between one side (100) of the door frame and the door and a bottom surface of the sealing part (220).

Generally, a door frame or a door is manufactured by bending a metal plate several times and then joining the joints. That is, since the door frame or the door is a three-dimensional body surrounded by a metal plate, one side of the door frame or the door to which the packing portion can be coupled can be formed into a metal plate.

The thickness of the metal plate is not particularly limited, but may be less than the length of the connecting portion. If the thickness of the metal plate exceeds the length of the connection portion, it is not easy to connect the packing portion, and even if the metal plate is coupled, an excessive tension is applied to the connection portion 230 and the durability of the packing portion 200 may be deteriorated.

At least one of the through holes 110 may be provided on at least one side 100 of the door frame and the door, and the plurality of through holes 110 may be spaced apart from each other at predetermined intervals, for example, Lt; / RTI >

The diameter of the through hole 110 is the same as the diameter of the connection part 230 in consideration of the fixing force or the coupling force of the packing part 200, 210 and the bottom surface of the hermetic seal 220.

When the sizes of the through hole 110 and the packing part 200 are within the above ranges, the bottom surfaces of the sealing part 220 and the coupling part 210 form a step with respect to the through hole 110, The fixing force of the packing part 200 is maintained by the step, and it is possible to prevent the packing part 200 from being arbitrarily detached during the opening and closing of the door.

Further, when the packing part 200 depends only on the clamping force by the step, the parts 210, 220 and 230 of the packing part 200 may be damaged during long-term use. Particularly, when the surface of the connection part 230 is damaged, a clearance is generated between the connection part 230 and the through hole 110, so that it is difficult to maintain the fixing force of the packing part 200.

Accordingly, an adhesive layer 300 may be additionally provided between one side 100 of the door frame and the door, and the lower surface of the sealing part 220 to improve the fixing force of the packing part, .

The adhesive constituting the adhesive layer 300 may be a known one used for attaching an elastic body on a metal plate, and the kind and composition thereof are not particularly limited.

The packing part 200 may include a plurality of fastening parts 210, a sealing part 220 for sealing between the door and the door frame when the sealing part 200 is closed, and a connecting part 230 for connecting the fastening part and the sealing part. And the end face of the coupling part 210 and the closing part 220 may be a semicircular or semi-circular cross-section. The coupling part 210, the closing part 220, and the coupling part 230 may be integrally formed. It may be elliptical.

The restoring force of the sealing part 220 due to the opening and closing of the door is a factor that directly affects the service life or replacement period of the packing part 200. The packing part attached to or fixed to the door frame or door is an elastic soft material and can be pressed against each other at the time of closing the door. Since the sealing part 220 of the packing part 200 repeats deformation and restoration (recovery) according to the opening and closing of the door, minimizing such deformation and maximizing the restoring force can prolong the life or replacement period of the packing.

The restoring force of the sealing part 220 integrally formed with the coupling part 210 and the coupling part 230 may vary depending on the shape of the end surface but may be changed when the shape of the end surface is semicircular or semi-elliptical, 220 are curved, the restoring force can be maximized.

In addition, the sealing part 220 may be a tubular type with an empty interior, a columnar type integrated with the same material inside and outside, or a filled type in which a specific material is filled in a tubular packing, no.

In the case of the tubular type, since the interior is made hollow, the restoring force of the elastic body constituting the closed portion can be improved, so that the deformation or damage of the closed portion due to the opening and closing of the door can be prevented.

In the case of the column type, since the inside and the outside are made of the same material, the manufacturing is easy and the inside is filled with the elastic body, the sealing force against the area connected to the door when the door is closed can be improved.

In the case of the above-mentioned filling type, the tubular sealing portion is filled with a specific substance, and filling of a soft material or a magnetic substance can improve the sealing force with respect to a region connected to the door when the door is closed.

Particularly, in the case of using a tubular sealing part filled with a magnetic material therein, an additional attractive force can act between the door made of the magnetic material and the metal plate, thereby improving the sealing force of the part connected to the door.

The length of the connection part 230 may be equal to or greater than the thickness of the door 100 or the one side 100 of the door frame. If the thickness of the one side 100 of the door or the door frame exceeds the length of the connection part 230, it is not easy to connect the packing part 200 and excessive tension is applied to the connection part 230 The durability of the packing part 200 may be lowered.

3 is a cross-sectional view of a packing portion according to another embodiment of the present invention; Referring to FIG. 3, the sealing part 220 may further include a core 221 inserted therein.

The core 221 inserted into the sealing part 220 is made of a metal material and can reinforce the durability of the sealing part 220 and the packing part 200 made of a soft elastic material, It is possible to prevent abrasion phenomenon, deformation,

The end face of the core member 221 may be a plate shape, a circular shape, an elliptical shape, a semicircular shape or a semi-elliptical shape, and preferably a semicircular or semi-elliptical shape similar to the shape of the sealing portion 220, no.

The metal material may be selected from the group consisting of iron, copper, aluminum, and alloys containing two or more of them, preferably iron or copper, but is not limited thereto.

The core member 221 may be inserted at a proper position inside the sealing portion 220 considering the seating distance to one side of the packing portion or the door or the door frame facing each other when the door is closed.

4 and 5 are perspective views of a coupling structure of a packing part according to another embodiment of the present invention. The plurality of through holes 110 may be formed in a line at predetermined intervals on the first row and the second row, respectively.

When the plurality of through holes 110 formed in a row at predetermined intervals are formed in two or more rows, the fixing force and durability of the packing portion can be further improved as compared with a case where the plurality of through holes 110 are formed in a single row.

Referring to FIG. 4, the through holes 110 formed in a row on the first and second rows may face each other. When the fastening part 210 of the packing part 200 corresponding to one through hole provided on the first row is broken, the through hole 110 and the fastening part 210 provided on the second row, 210 can be prevented from deteriorating in the fixing force at the damaged portion. That is, the coupling structures of the through holes 110 and the coupling portions 210 corresponding to the through holes 110 provided on the first and second rows complement each other to maintain the fixing force of the packing portion 200 .

Referring to FIG. 5, the through holes 110 formed in a row on the first and second rows may be staggered. In the case where the through holes 110 formed in a row on the first and second rows are offset from each other, it is possible to prevent a decrease in fixing force that may occur in the portion between the through holes 110 provided in each row.

For example, when the space between the through holes 110 provided in the first and second rows is 10 cm, and the through holes 110 and the corresponding coupling portions 210 are formed in a shifted pattern, The distance between the coupling structure of the through hole 110 and the coupling part 210 can be reduced to less than 10 cm by the combination of the second row.

Particularly, if the through hole 110 provided on the first row is shifted to be positioned in the center of the through hole 110 provided on the second row, the through hole 110 and the corresponding coupling portion 210 May be reduced to half the interval of the through holes 110 located on the first or second row.

That is, when the through holes 110 formed in a row on the first and second rows are staggered, as shown in FIG. 4, the through holes 110 of the first and second rows, The coupling structure of the packing part 210 can complement each other to maintain the fixing force of the packing part 200 and the gap of the coupling structure can be substantially denser to improve the fixing force of the packing part 200 .

6 and 7 are cross-sectional views of a fire door according to an embodiment of the present invention, in which the coupling structure of a packing part is provided in a door frame and a door.

Referring to FIG. 6, the packing part 200 may be provided on one end face of the inner surface of the door, and on one side of the door frame that contacts the end part when the door is closed. The end portions of the door and the door frame are each of a "C" type, and such a shape can be manufactured only by bending two times, which is advantageous in terms of workability and economy.

Referring to FIG. 7, the door frame may have at least one step. Generally, two bending operations per single step are required to be performed additionally, so that workability and economical efficiency may be deteriorated. However, when a plurality of steps are formed on a door or a door frame, the sealing performance can be improved. Therefore, So that at least one step can be formed on the door or the door frame.
