Description

방화문의 열변형 방지장치Thermal deformation prevention device of fire door
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 한 방화문의 열변형 방지장치에 관한 것이다.The present invention relates to a thermal deformation preventing device of a fire door, and more particularly, to prevent fire when the fire door is deformed due to the deformation of the fire door due to the high temperature of the indoor side to improve the reliability of the product, in particular, the fire resistance test The present invention relates to a thermal deformation preventing device of a fire door that can pass through.
일반적으로, 아파트나 가정 및 사무실 등의 현관에는 화재가 발생할 경우 화염의 전달을 방지할 목적으로 철판으로 구성된 방화문을 주로 설치하고 있다.In general, fire doors made of steel plates are mainly installed in the entrances of apartments, homes and offices in order to prevent the transmission of flames in the event of a fire.
종래의 방화문을 살펴보면, 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. Looking at the conventional fire door, as shown in Figure 1, the door frame frame 200 of the size surrounding the outside of the fire door body 100 is fixed to the building, the hinge between the door frame frame 200 and one side of the fire door body 100 300 will be installed.
문틀후레임(200)과 방화문 본체(100) 사이의 접촉부에는 소음방지와 단열 및 개폐시 완충을 위해 가스켓부재(400)를 설치하기도 한다. The contact portion between the door frame frame 200 and the fire door main body 100 may be provided with a gasket member 400 for noise prevention, heat insulation, and buffering during opening and closing.
또, 방화문 본체(100)와 문틀후레임(200) 사이에 개폐가 용이하도록 틈새를 형성하게 되는데, 이 틈새를 도 2에서와 같이 "T" 단면의 날개 형상으로 된 가스켓(600)으로 차단하기도 한다. In addition, a gap is formed between the fire door main body 100 and the door frame frame 200 to facilitate opening and closing. The gap may be blocked by a gasket 600 having a wing shape having a “T” cross section as shown in FIG. 2. .
따라서, 가스켓(600)과 가스켓부재(400)는 방화문 본체(100)와 문틀후레임(200) 사이의 틈새를 밀폐시키고, 화재발생 시 가스가 실내로 유입되는 것을 차단하고, 방화문 본체(100)가 닫히면서 문틀후레임(200)과 부딪쳐 발생되는 소음을 방지하며, 외부공기와 내부공기를 차단시켜 실내 단열효과를 얻을 수 있도록 해준다. Thus, the gasket 600 and the gasket member 400 seals the gap between the fire door body 100 and the door frame frame 200, blocks gas from entering the room during a fire, and the fire door body 100 is It prevents the noise generated by closing the door frame frame (200) while closing, it is possible to obtain the interior insulation effect by blocking the outside air and the internal air.
방화문 본체(100)의 내부 둘레에는 보강부재(700)가 주로 용접이나 비스에 의해 고정 부착되며, 내부에는 단열재(150)가 채워지게 된다. 이 단열재(150)는 합성수지계열의 바인더에 의해 형성되어 있고, 이는 철판과 무기성분 본드를 이용하여 부착 고정된다.The reinforcement member 700 is fixedly attached to the inner circumference of the fire door main body 100 by welding or a vis, and the heat insulating material 150 is filled therein. The heat insulator 150 is formed of a synthetic resin binder, which is attached and fixed using an iron plate and an inorganic component bond.
이와 같이 이루어진 종래 방화문은 단열을 위해 내부에 단열재를 채우고, 그 외곽은 전부 금속판재로 이루어져 있다. Conventional fire doors made in this way is filled with a heat insulating material inside for the insulation, the outer portion is made of a metal plate all.
화재가 발생될 경우, 종래의 방화문 본체(100)는 밀폐된 실내 온도가 높아지게 되고, 그 경우 일차적으로 상하, 좌우 길이 방향으로 열변형이 일어나게 되고, 단면 내부에 채워지는 단열재(150)의 바인더가 연소되어 가스가 방출되면서 열과 가스압력에 의해 팽창과 동시에 강도가 취약한 부분에서 비틀림이 발생하게 된다.(도 3)When a fire occurs, the conventional fire door main body 100 is the sealed room temperature is high, in this case, the thermal deformation occurs in the vertical direction, vertically, left and right longitudinal direction, the binder of the heat insulating material 150 is filled in the cross section As the gas is combusted and burned out, torsion occurs in a portion where strength is weak at the same time as expansion due to heat and gas 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 twist phenomenon is that the fire door main body 100 is particularly severely twisted at the corner opposite the hinge 300 than the hinge 300 is connected to the door frame 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, the inner surface of the fire door main body 100 is in contact with the gasket member 400, a gap is opened between the door frame frame 200, the flame leaks to the outside along with harmful gas, the fire spreads and causes more casualties It would have been.
이러한 문제점을 위해 방화문 안전 규범에서는 1000도 이상의 고온에서도 변형이나 파손되지 않는 것을 규정하고 있으나, 종래 방화문의 구조는 이러한 규정을 현실적으로 통과하지 못하고 있다.For this problem, the fire door safety norm stipulates that deformation or damage does not occur even at a high temperature of more than 1000 degrees, but the structure of a conventional fire door does not realistically pass such a rule.

상기 방화문 본체(100)는 내부로 속이 빈 공간을 가지며 전체적으로 문짝 형상을 갖도록 내측부재와 외측부재가 거리를 유지한 상태로 테두리부재(110)에 의해 둘레가 마감된 상태로 그 내부에는 통상적으로 단열재(150)가 채워지게 된다.The fire door main body 100 has a hollow space therein and the inner member and the outer member to maintain the distance to the overall shape in a state that the circumference is closed by the border member 110 in a state that is generally insulated inside 150 will be filled.
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.The heat insulating material 150 is filled with a thin fibrous resin material having excellent heat insulating effect. The heat insulating material 150 is fixedly attached to the internal space of the fire door main body 100 while maintaining a state of mutual bonding by a binder of a synthetic resin series.
상기 문틀후레임(200)은 방화문 본체(100)의 외곽을 감싸며 건축물에 고정 설치되며, 방화문 본체(100)의 개폐를 위해 일측에는 힌지(300)가 연결된다.The door frame frame 200 is fixed to the building surrounding the outer door of the fire door main body 100, the hinge 300 is connected to one side for opening and closing the fire door main body (100).
그리고, 문틀후레임(200)에는 오목한 홈부를 성형하여 방화문 본체(100) 사이를 단열시킴과 아울러 기밀성과 차음성을 갖도록 하기 위해 준불연소재의 가스켓부재(400)가 설치된다.In addition, the door frame frame 200 is provided with a gasket member 400 of a semi-combustible material in order to form a concave groove to insulate the fire door body 100 and to have airtightness and sound insulation.
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.Typically, between the door frame frame 200 and the fire door main body 100 to form a gap between about 3-5 mm for smooth opening and closing, the fire door has a gasket 600 having a wing shape having a "T" cross section. The wing portion may block a gap formed between the fire door main body 100 and the door frame frame 200 to facilitate opening and closing.
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. Therefore, the wing part to prevent the door frame frame 200 and the fire door main body 100 is connected to the metal to obtain a condensation prevention effect, to improve the airtightness and sound insulation as a result of completely blocking the indoor and outdoor It could be.
한편, 본 발명은 방화문 본체(100)에 고열이 전달될 때 로크몸체(510)가 문틀 후레임(200)에 뚫어지는 로크구멍(210)으로 끼워 로크상태를 유지하는 것에 의해 방화문의 비틀림을 억제하는 것을 구성상의 특징으로 한다. On the other hand, the present invention is to suppress the torsion of the fire door by holding the lock body 510 is inserted into the lock hole 210 which is drilled in the door frame frame 200 when high heat is transmitted to the fire door main body 100 It is characterized by the configuration.
즉, 상기 방화문 본체(100)에는 스프링(520)의 탄력을 압축한 상태로 로크몸체(510)를 수용하고 있는 하우징(500)을 고정 설치하게 된다.That is, the fire door main body 100 is fixed to the housing 500 which accommodates the lock body 510 in a state in which the elasticity of the spring 520 is compressed.
하우징(500)은 중앙에 하부를 향해 원통형의 수용 공간이 파여지고, 상부 양단에는 조립구멍(502)이 뚫어지는 브라켓트(501)가 일체로 절곡 성형되어 있다.In the housing 500, a cylindrical accommodation space is dug downward in the center thereof, and brackets 501 through which the assembling holes 502 are drilled are integrally bent at both ends of the housing 500.
따라서, 방화문 본체(100)에는 하우징(500)과 브라켓트(501)가 돌출되지 않은 상태로 하우징(500)은 내부로 수용되도록 오목하게 홈부(101)를 형성하고, 브라켓트(501)의 상부면은 테두리부재(110)와 같은 높이를 갖도록 성형한 상태에서, 비스(1)를 이용해 방화문 본체(100)의 테두리부재(110)에 나사 체결되어 고정 설치되는 것이다.Therefore, in the fire door main body 100, the housing 500 and the bracket 501 are not protruded, and the housing 500 is recessed so as to be accommodated therein, and the upper surface of the bracket 501 is formed. In a state of molding to have the same height as the frame member 110, the screw is fastened to the frame member 110 of the fire door main body 100 by using the screw (1).
이 하우징(500)에는 스프링(520)과 로크몸체(510)가 내부로 수용된 상태에서, 막음판(530)으로 로크몸체(510)가 돌출되는 것을 차단시키게 된다.(도 5 및 도 8 참조.)In the housing 500, the spring 520 and the lock body 510 are accommodated therein, thereby preventing the lock body 510 from protruding from the blocking plate 530 (see FIGS. 5 and 8). )
상기 막음판(530)은 화재 발생에 의해 용융가능한 납, 알루미늄 또는 합성수지재 중 어느 하나로 선택된다. The blocking plate 530 is selected from any one of lead, aluminum, or synthetic resin material that can be melted by fire.
그리고, 상기 문틀 후레임(200)에는 로크몸체(510)가 돌출 위치로 로크구멍(210)을 뚫거나 오목하게 파내게 된다.In addition, the lock body 510 drills or recesses the lock hole 210 in the protruding position in the door frame frame 200.
이때, 문틀 후레임(200)에는 뚫어지는 로크구멍(210)을 홀캡(220)으로 보호하는 것이 좋다.At this time, the door frame frame 200 may be protected by the hole cap 220 to the lock hole 210 to be drilled.
따라서, 막음판(530)에 의해 로크몸체(510)가 하우징(500) 내부로 수용된 상태에서 화재나 내화성능 테스트에 의해 고열이 전달되면 용융온도가 낮은 재질로 된 막음판(530)이 열에 의해 녹아버리게 된다.Therefore, when high temperature is transmitted by fire or fire resistance test in a state in which the lock body 510 is accommodated into the housing 500 by the blocking plate 530, the blocking plate 530 made of a material having a low melting temperature is heated by heat. Will melt.
이 막음판(530)은 적어도 200 ℃ 이상의 고온이 전달되면 용융되는 재질로 납이나, 얇은 두께의 알루미늄, 또는 합성수지재로 제작되므로 화재가 발생되면, 스프링(520)의 압축 탄력을 억지한 상태로 하우징(500) 내부로 수용되어 있던 로크몸체(510)의 막음 기능이 상실된다. Since the blocking plate 530 is made of a material that is melted when a high temperature of at least 200 ° C. or higher is transmitted, it is made of lead, a thin aluminum, or a synthetic resin material, and thus, when a fire occurs, the spring 520 is restrained from compression. The blocking function of the lock body 510 accommodated inside the housing 500 is lost.
막음판(530)이 용융되면 로크몸체(510)는 스프링(520)의 탄력으로 하우징(500)으로부터 튀어나 문틀 후레임(200)의 로크구멍(210)으로 끼워져 방화문 본체(100)와 문틀후레임(200)이 로크상태를 유지하게 된다. When the blocking plate 530 is melted, the lock body 510 pops out of the housing 500 by the elasticity of the spring 520 and is inserted into the lock hole 210 of the door frame frame 200 so that the fire door main body 100 and the door frame frame ( 200) to remain locked.
따라서, 화재나 내화성능 테스트시 열변형에 의해 방화문 본체(100)가 고열의 전달로 팽창과 비틀림이 발생되는 것을 차단할 수가 있는 것이다.Therefore, the fire door main body 100 can prevent the expansion and torsion caused by the transfer of high heat due to heat deformation during the fire or fire resistance performance test.
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.As such, when the torsion of the fire door main body 100 is prevented, a gap is not generated between the door frame frames 200, and in particular, the gasket member 400 maintains a close contact with the inner surface of the fire door main body 100. This can help to prevent indoor flames and harmful gases from leaking to the outside.
한편, 상기 스프링(520)은 설정된 온도에 의해 변형되는 형상기억금속재로 성형될 수도 있다. On the other hand, the spring 520 may be molded of a shape memory metal material deformed by a set temperature.
형상기억금속으로 된 스프링(520)의 기억 온도는 200 ℃ 이상 고온으로 제작하는 것에 의해 화재나 내화성능 테스트시 고열이 전달되면, 도 6과 같이 스프링(520) 형상이 변형되면서 로크몸체(510)가 후레임(200)의 로크구멍(210)으로 끼워져 방화문 본체(100)와 문틀후레임(200)이 로크상태를 유지하게 된다.When the high temperature is transmitted during a fire or fire resistance test by the storage temperature of the spring 520 made of shape memory metal at a high temperature of 200 ° C. or higher, the lock body 510 is deformed as shown in FIG. 6. Is inserted into the lock hole 210 of the frame 200 so that the fire door main body 100 and the door frame frame 200 remain locked.
여기서, 상기 로크몸체(510)를 수용하고 있는 하우징(500)은 방화문 본체(100)의 상부면과 문틀 후레임(200) 사이에 일정간격 여러 곳에 설치되는 것이 바람직 하나, 방화문 본체(100)의 측면과 문틀 후레임(200) 사이에 더 설치하는 것도 무방하다. Here, it is preferable that the housing 500 accommodating the lock body 510 is installed at a predetermined interval between the upper surface of the fire door main body 100 and the door frame frame 200, and the side of the fire door main body 100. And may be installed between the door frame frame 200 more.
상기 로크몸체(510)에는 축직각 방향으로 손잡이(540)를 체결하여, 이 손잡이(540)가 상하 작동될 수 있는 길이로 하우징(500)에는 안내홀(505)을 수직하게 뚫게 된다.The handle 540 is fastened to the lock body 510 in the axially perpendicular direction, and the guide hole 505 is vertically drilled in the housing 500 to a length at which the handle 540 can be vertically operated.
또, 방화문 본체(100)에도 손잡이(540)가 상하 작동될 수 있는 길이로 안내구멍(102)을 뚫어 로크몸체(510)가 돌출되어 로크상태에서 원위치시키거나 설치과정에서 셋팅 조작이 가능하게 한다. In addition, the fire door main body 100 also penetrates the guide hole 102 to the length that the handle 540 can be operated up and down to protrude the lock body 510 to the original position in the locked state or to enable the setting operation in the installation process. .
이러한 본 발명에 의하며, 화재 범위가 번지거나 하는 위험한 경우로부터 안전하게 지킬 수 있다.According to the present invention, it can be safely kept from the dangerous case of spreading the fire range.
또, 내화 성능 테스트도 통과할 수 있는 것이다.In addition, it can pass the fire resistance performance test.
