본 발명은 방화문의 열변형 방지장치에 관한 것으로, 더욱 상세하게는 화재 발생시 실내측 고열에 의해서 방화문이 변형되면서 화염이 실외로 분출되는 경우를 차단하여 제품의 신뢰성을 향상시키고, 특히 내화성능 테스트도 통과할 수 있도록 발명된 것이다.
More particularly, the present invention relates to an apparatus for preventing thermal deformation of a fire door, and more particularly, it relates to an apparatus for preventing thermal deformation of a fire door, It was invented to be able to pass.

일반적으로, 아파트나 가정 및 사무실 등의 현관에는 화재가 발생할 경우 화염의 전달을 방지할 목적으로 철판으로 구성된 방화문을 주로 설치하고 있다.Generally, fire doors made of iron plates are installed in the front of apartments, homes, offices, etc. in order to prevent the transmission of flames in the event of a fire.

즉, 도 1에서와 같이 방화문 본체(100)의 외부를 감싸는 크기의 문틀후레임(200)을 건축물에 고정시키고, 문틀후레임(200)과 방화문 본체(100)의 일측 사이에는 힌지(300)를 설치하게 된다.1, a door frame 200 of a size that covers the exterior of the fire door main body 100 is fixed to a building and a hinge 300 is installed between the door frame 200 and one side of the fire door main body 100 .

그리고, 소음방지와 단열 및 개폐시 완충을 위해 문틀후레임(200)과 방화문 본체(100) 사이의 접촉부에는 가스켓부재(400)를 설치하기도 한다.A gasket member 400 may be provided at a contact portion between the door frame 200 and the fire door main body 100 for noise prevention, insulation, and buffering during opening and closing.

또, 방화문 본체(100)와 문틀후레임(200) 사이에 개폐가 용이하도록 틈새를 형성하게 되는데, 이 틈새를 "T" 단면의 날개 형상으로 된 가스켓(600)으로 차단하기도 한다.(도 2)In addition, a gap is formed between the fire door main body 100 and the door frame 200 to facilitate opening and closing, and this gap may be blocked by a gasket 600 having a blade shape of a "T" cross section (FIG. 2)

따라서, 가스켓(600)과 가스켓부재(400)에 의해 방화문 본체(100)와 문틀후레임(200) 사이의 틈새가 밀폐되어 화재발생 시 가스가 실내로 유입되는 것을 차단하고, 방화문 본체(100)가 닫히면서 문틀후레임(200)과 부딪쳐 발생되는 소음을 방지함은 물론 외부공기와 내부공기를 차단시켜 실내 단열효과를 얻을 수 있는 것이다.Therefore, the gap between the fire door main body 100 and the door frame 200 is sealed by the gasket 600 and the gasket member 400 to block the gas from entering the room when the fire occurs, and the fire door main body 100 It is possible to prevent noise generated by colliding with the door frame 200 when the door frame 200 is closed, as well as to block the outside air and the inside air, thereby achieving an indoor heat insulation effect.

방화문 본체(100)의 내부 둘레에는 보강부재(700)가 주로 용접이나 비스에 의해 고정 부착되며 내부에는 단열재(150)가 채워지게 된다.The reinforcement member 700 is fixed to the inner circumference of the fire door main body 100 mainly by welding or screws, and the insulator 150 is filled inside.

이 단열재(150)는 합성수지계열의 바인더에 의해 형성되어 있고, 이는 철판과 무기성분 본드를 이용하여 부착 고정된다.
The heat insulating material 150 is formed of a binder of a synthetic resin type, and is adhered and fixed using an iron plate and an inorganic component bond.

대한민국 특허 등록번호 10-0766199호(2007년10월04일 등록)Korea Patent Registration No. 10-0766199 (Registered on October 04, 2007) 대한민국 실용신안 등록번호 20-305989(2003년02월18일 등록)Korea Utility Model Registration No. 20-305989 (Registered February 18, 2003)

상기와 같이 구성된 종래 방화문의 구성은 단열을 위해 내부에 단열재를 채우고, 그 외곽은 전부 금속판재로 이루어져 있다.In the conventional fire door having the above-described construction, a heat insulating material is filled in the inside for the purpose of heat insulation, and the outside is entirely made of a metal plate material.

이와 같이 된 방화문 본체(100)는 화재 발생시 밀폐된 실내 온도가 높아지는 경우 일차적으로 상하, 좌우 길이 방향으로 열변형 된 후 단면 내부에 채워지는 단열재(150)의 바인더가 연소되어 가스가 방출되면서 열과 가스압력에 의해 팽창과 동시에 강도가 취약한 부분에서 비틀림이 발생하게 된다.(도 3)In the fire door main body 100 having such a structure, when the enclosed room temperature becomes high in the event of a fire, the binder of the heat insulating material 150, which is firstly thermally deformed in the vertical direction and the left and right direction, is burnt, The torsion occurs at the portion where the strength is weakened at the same time as the expansion due to the pressure (Fig. 3).

비틀림 현상은 힌지(300)가 문틀후레임(200)에 연결된 부분보다 힌지(300) 반대쪽 코너에서 방화문 본체(100)가 특히 심하게 비틀림 현상이 나타나게 된다.The torsion phenomenon is particularly severe in the main body 100 of the fire door at the corner opposite to the hinge 300 than the portion where the hinge 300 is connected to the door frame 200.

이때, 방화문 본체(100)의 내측면이 가스켓부재(400)와 접촉이 떨어지고, 문틀후레임(200)의 사이에는 틈새가 벌어져 유해가스와 함께 화염이 외부로 누출되어 화재가 번져 인명피해가 커지는 원인이 되었던 것이다.At this time, since the inner side of the fire door main body 100 is in contact with the gasket member 400, a gap is formed between the door frames 200, and the flame is leaked to the outside together with the noxious gas, .

이러한 문제점을 위해 방화문 안전 규범에서는 1000도 이상의 고온에서도 변형이나 파손되지 않는 것을 규정하고 있으나, 종래 방화문의 구조는 이 규정을 현실적으로 통과하지 못하고 있다.In order to solve these problems, it is stipulated that the fire safety gate does not deform or break even at a high temperature of more than 1000 degrees.

본 발명의 목적은 특히 화재 발생에 의한 고열에도 변형으로 인해 유해가스와 화염이 누출되는 경우를 미연에 방지하여 제품의 안전도와 신뢰성을 향상시킬 수 있는 방화문을 제공하는 데 있다.An object of the present invention is to provide a fire door capable of preventing the leakage of noxious gases and flames due to deformation due to high temperature caused by a fire, thereby improving the safety and reliability of the product.

본 발명의 다른 목적은 안전 규정에도 적합하여 내화성능을 충족할 수 있도록 한 방화문을 제공하는 데 있다.
Another object of the present invention is to provide a fire door which is suitable for safety regulations and can satisfy fire resistance performance.

상기한 바와 같은 목적을 달성하기 위하여, 본 발명은 속이 빈 상태의 문짝형상으로 문틀 후레임(200)에 힌지(300)로 개폐 가능하게 연결되고, 테두리부재(110)의 내측으로 보강부재(700)가 고정부착된 상태로 방화문 본체(100)의 내부로 단열재(150)가 채워지는 방화문 본체(100)에 있어서,
상기 방화문 본체(100)에 평상시에서는 문틀 후레임(200)의 내측면과 거리(S)를 유지한 상태로 설치되며, 화재에 의해 고열이 전달되어 열변형에 의해 신장될 때는 방화문 본체(100)의 열팽창으로 문틀 후레임(200)의 내측면에 압착되어 비틀림을 억제하도록 방화문 본체(100)의 테두리부재(110)의 나사구멍(111)과, 이 나사구멍(11)에 동일 위치로 보강부재(700)에 뚫어지는 나사홀(701)에 각각 2중으로 나사 체결되며 머리에는 일체로 예리하게 칼날부(511)를 갖는 가압볼트(510)가 설치되는 것을 특징으로 한다.In order to achieve the above object, according to the present invention, a hinge (300) is openably and closably connected to a door frame frame (200) in a hollow door shape, and a reinforcing member (700) In the fire door main body 100 in which the heat insulating material 150 is filled into the inside of the fire door main body 100 in a state where the heat insulating material 150 is fixedly attached,
The fire door 120 is installed in the fire door main body 100 while keeping the distance S from the inner side face of the door frame 200. When the fire is transmitted due to high heat and is expanded by thermal deformation, The threaded hole 111 of the frame member 110 of the fire door main body 100 and the reinforcing member 700 in the same position in the screw hole 11 are pressed against the inner surface of the frame frame 200 by thermal expansion, And a pressing bolt 510 having a sharp blade part 511 integrally formed on the head is installed in the head.

이하 본 발명의 바람직한 실시예를 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 내지 도 7은 본 발명이 적용된 방화문의 열변형 방지장치 구조를 도시하고 있다.
상기 방화문 본체(100)는 내부로 속이 빈 공간을 가지며 전체적으로 문짝 형상을 갖도록 내측부재와 외측부재가 거리를 유지한 상태로 테두리부재(110)에 의해 둘레가 마감된다.
그리고, 방화문 본체(100)의 내부에는 강도 보강을 위해 테두리부재(110)의 내측으로 보강부재(700)가 설치된 상태로 내부 공간에는 통상적으로 단열재(150)가 채워지게 된다.
단열재(150)는 단열 효과가 우수한 가는 섬유형상의 수지재로 채워지는데, 합성수지계열의 바인더에 의해 상호 결합상태를 유지한 상태로 방화문 본체(100)의 내부 공간에 고정 부착된다.
상기 문틀후레임(200)은 방화문 본체(100)의 외곽을 감싸며 건축물에 고정 설치되며, 방화문 본체(100)의 개폐를 위해 일측에는 힌지(300)가 연결된다.
그리고, 문틀후레임(200)에는 오목한 홈부를 성형하여 방화문 본체(100) 사이를 단열시킴과 아울러 기밀성과 차음성을 갖도록 하기 위해 준불연소재의 가스켓부재(400)가 설치된다.
통상적으로 문틀후레임(200)과 방화문 본체(100) 사이에는 개폐의 원활함을 위해 약 3-5 mm 사이의 틈새를 형성하게 되므로, 방화문에는 "T" 단면의 날개 형상으로 된 가스켓(600)이 설치되어 날개부가 방화문 본체(100)와 문틀후레임(200) 사이에 개폐가 용이하도록 형성된 틈새를 차단하기도 한다.
따라서, 이 날개부가 문틀후레임(200)과 방화문 본체(100)가 금속으로 연결되는 것을 차단하여 결로방지 효과를 얻을 수 있도록 하고, 실내와 실외를 완전하게 차단시키는 결과로 기밀성과 차음성을 향상시킬 수도 있는 것이다.
한편, 본 발명은 방화문 본체(100)에 주로 화재에 의해 고열이 전달되어 열변형에 의해 신장될 때 문틀 후레임(200)에 압착되어 비틀림을 억제하는 가압볼트(510)가 설치된다.
이 가압볼트(510)는 도 4 및 도 7에서 도시한 바와 같이 방화문 본체(100)의 테두리부재(110)와 보강부재(700)에 각각 나사 체결되어 견고하게 고정 설치된다.
즉, 도 4 및 도 6에서 도시한 바와 같이 방화문 본체(100)의 테두리부재(110)에 뚫어진 나사구멍(111)과, 이 나사구멍(111)에 동일 위치로 보강부재(700)에는 나사홀(701)을 각각 뚫어 가압볼트(510)가 나사구멍(111)과 나사홀(701) 모두에 2중으로 견고하게 일정 높이로 나사 체결하게 된다.
이때, 가압볼트(510)의 머리 설치 높이는 평상시 방화문 본체(100)가 개폐될 때 문틀 후레임(200)에 접촉되지 않을 정도로 내측면과 거리(S)를 유지한 상태로 나사 체결 높이를 조절하게 된다.(도 5)
이 상태에서 화재나 내화성능 테스트에 의해 실내측에 1000도씨 전후의 고열이 전달되면, 일차 열변형에 의해 방화문 본체(100)가 상하, 좌우 길이 방향으로 각각 신장될 때 가압볼트(510)의 머리부가 문틀 후레임(200)의 내측면에 가압상태로 접촉된다.(도 6 및 도 7)
이때, 상기 가압볼트(510)의 머리에는 일체로 예리하게 칼날부(511)가 성형되어 있으므로 큰 가압력을 전달할 수 있는 것이다.
또, 비틀림 방향으로 변형력이 발생되더라도 가압된 상태에서 미끄럼을 최대한 방지할 수 있는 것이다.
따라서, 가압볼트(510)의 머리에 형성된 칼날부(511)가 문틀 후레임(200)의 내측면과 강하게 압착상태로 있게 되므로 열변형에 의해 방화문 본체(100)가 신장된 후 계속되는 고열의 전달로 팽창과 비틀림이 발생되는 것을 차단할 수가 있는 것이다.
이와 같이 방화문 본체(100)의 비틀림이 방지되면 문틀 후레임(200) 사이에 틈새가 발생되지 않게 되고, 특히 가스켓부재(400)가 방화문 본체(100)의 내측면과 밀착상태를 계속 유지하게 되는 결과로 실내 화염과 유해가스가 외부로 누출되는 것을 차단하는데 도움을 줄 수가 있는 것이다.
이와 같이 가압볼트(510)를 나사구멍(111)과 나사홀(701)에 각각 2중으로 나사 체결하여는 것에 의해 유동되지 않고 견고하게 가압볼트(510)를 체결 고정시킬 수 있게 된다.
여기서, 상기 가압볼트(510)는 방화문 본체(100)의 상부면과 문틀 후레임(200) 사이에 일정간격 수곳에 설치되는 것이 바람직 하나, 방화문 본체(100)의 측면과 문틀 후레임(200) 사이에 더 설치하는 것도 무방하다
이러한 본 발명에 의하며, 화재 범위가 번지거나 하는 위험한 경우로부터 안전하게 지킬 수 있다.
또, 내화 성능 테스트도 통과할 수 있는 것이다.
FIG. 7 is a view showing a structure of a device for preventing thermal deformation of a fire door to which the present invention is applied.
The fire door main body 100 has a hollow space therein, and the periphery thereof is closed by the frame member 110 while keeping the distance between the inner member and the outer member so as to have a total door shape.
The interior space of the fire door main body 100 is filled with the heat insulating material 150 in a state where the reinforcement member 700 is installed inside the frame member 110 to reinforce the strength.
The heat insulating material 150 is filled with a resin material having a good thermal insulation effect and is fixedly attached to the inner space of the fire door main body 100 in a state in which the mutually connected state is maintained by a synthetic resin binder.
The door framing frame 200 is fixed to the building and surrounds the exterior of the fireproofing door body 100. A hinge 300 is connected to one side of the door frame frame 100 for opening and closing the door.
The door frame frame 200 is provided with a gas-impermeable gasket member 400 for forming a concave groove portion to insulate between the fire door main bodies 100 and to provide airtightness and sound insulation.
A gap of about 3-5 mm is formed between the frame frame 200 and the fire door main body 100 for smooth opening and closing. Thus, a gasket 600 having a "T" So that the wing portion can block a gap formed between the fire door main body 100 and the door frame 200 to facilitate opening and closing.
Accordingly, the wings can prevent the door frames 200 and the fire door main body 100 from being connected to each other by metal, thereby achieving a dew condensation preventing effect. As a result, the indoor air and the outdoor air are completely blocked, It is possible.
In the meantime, according to the present invention, when a high heat is transmitted to the fire door main body 100 by fire and is stretched by thermal deformation, the press bolt 510 is pressed against the door frame 200 to suppress twisting.
As shown in FIGS. 4 and 7, the pressing bolt 510 is tightly fixed to the frame member 110 of the fire door main body 100 and the reinforcing member 700, respectively.
4 and 6, a screw hole 111 is formed in the frame member 110 of the fire door main body 100 and a screw hole (not shown) is formed in the reinforcing member 700 at the same position in the screw hole 111, So that the press bolt 510 is tightly fastened to both the screw hole 111 and the screw hole 701 at a constant height.
At this time, the height of the head of the press bolt 510 is adjusted so as to maintain the distance S with respect to the inner surface of the door frame frame 200 so as not to contact the door frame 200 when the fire door main body 100 is normally opened or closed . (Fig. 5)
In this state, when a high heat of about 1000 degrees Celsius is transmitted to the indoor side by fire or fire resistance performance test, when the fire door main body 100 is extended in the vertical direction, the left and right direction by the primary thermal deformation, The head is brought into contact with the inner surface of the frame frame 200 in a pressurized state (Figs. 6 and 7)
At this time, since the blades 511 are formed integrally and sharply at the head of the pressing bolt 510, a large pressing force can be transmitted.
In addition, even if a deforming force is generated in the torsion direction, sliding can be prevented as much as possible in a pressurized state.
Therefore, since the knife portion 511 formed on the head of the pressing bolt 510 is in a strongly pressed state with the inner surface of the door frame 200, the fire door main body 100 is stretched by thermal deformation, It is possible to prevent the expansion and twisting from occurring.
When the torsion of the fire door main body 100 is prevented as described above, a gap is not generated between the door frame frames 200, and in particular, as a result that the gasket member 400 keeps a close contact state with the inner side surface of the fire door main body 100 This can help to prevent the indoor flames and harmful gases from leaking to the outside.
By screwing the press bolt 510 into the screw hole 111 and the screw hole 701 in this manner, the press bolt 510 can be tightly fixed without being flowed.
The pressing bolt 510 may be installed between the upper surface of the fire door main body 100 and the door frame 200 at a predetermined interval. However, the pressing bolt 510 may be disposed between the side surface of the door 100 and the door frame 200 It's okay to install more
According to the present invention, it is possible to safely keep from a dangerous situation in which a fire range is spread.
In addition, fire resistance performance test can be passed.
