Description

방화문의 가스켓 오토씰링 장치{A gasket auto sealing system of fire door}Gasket auto sealing system of fire door

본 발명은 방화문의 가스켓 오토씰링 장치에 관한 것으로, 더 상세하게는 실내와 실외의 공기를 차단하기 위한 가스켓을 방화문이 개폐될 때 자동으로 승강 작동될 수 있도록 발명된 것이다.
The present invention relates to a gasket auto-sealing device of the fire door, and more particularly to the gasket for blocking the air of the indoor and outdoor to be automatically lifted operation when the door is opened and closed.

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

방화문은 벽멱에 설치되는 반화문용 문틀프레임에 개폐 가능하게 장착되며, 이 문틀프레임도 철재 금속판으로 제조된다.The fire door is mounted on the wall panel so that it can be opened and closed. The door frame is also made of steel sheet metal.

종래, 일반적으로 건축물에 방화문을 설치하는 구조는 방화문(1)이 힌지(5)에 의해 개폐 가능하게 하면서 그 외부를 감싸는 크기의 문틀프레임(2)을 건축물에 고정시키게 된다.Conventionally, a structure in which a fire door is installed in a building generally fixes the door frame frame 2 having a size surrounding the outside while allowing the fire door 1 to be opened and closed by the hinge 5.

그리고, 소음방지와 단열 및 개폐시 완충을 위해 문틀후레임(2)과 방화문(1) 의 하단 접촉부에는 도 1에서와 같이 가스켓(3)(4)를 한 곳 또는 두 곳에 설치하게 된다.Then, the gaskets (3) (4) are installed in one or two places at the lower contact portions of the door frame frame (2) and the fire door (1) for noise prevention, insulation and cushioning during opening and closing.

또, 방화문(1)은 일정두께의 금속판재로 절곡 성형되는데 내부에는 단열 및 흡음재 등이 채워진다.In addition, the fire door 1 is bent and formed into a metal plate of a predetermined thickness, the inside is filled with heat insulation and sound-absorbing material.

통상적으로 방화문(1)이 원활한 개폐를 위해 바닥면과의 틈새를 유지하게 설계되는데, 이 틈새를 가스켓(3)(4)으로 차단하게 된다.Typically, the fire door 1 is designed to maintain a gap with the bottom surface for smooth opening and closing, which is blocked by the gasket (3) (4).

따라서, 가스켓(3)(4)에 의해 방화문(1)과 문틀프레임(2) 사이의 틈새가 밀폐되어 화재발생 시 가스가 실내로 유입되는 것을 차단하고, 방화문(1)이 닫히면서 문틀프레임(2)과 부딪쳐 발생되는 소음을 방지함은 물론 외부공기와 내부공기를 차단시켜 실내 단열효과를 얻을 수 있는 것이다.
Therefore, the gap between the fire door 1 and the door frame frame 2 is sealed by the gasket 3 and 4 to block gas from entering the room in the event of a fire, and the fire door 1 is closed, and the door frame frame ( In addition to preventing noise generated when bumping against 2), it is possible to obtain indoor insulation effect by blocking external air and internal air.

그러나, 종래 하부측 문틀프레임(2)에 방화문(1)에 접촉하도록 가스켓(4)을 설치하는 경우 가스켓(3)의 설치 두께를 감안하여 문틀프레임(2)의 돌출 높이가 매우 높아진다.However, in the case where the gasket 4 is installed to contact the fire door 1 on the lower side door frame 2, the protruding height of the door frame frame 2 becomes very high in view of the installation thickness of the gasket 3.

이 경우 바닥면으로부터 하부측 문틀프레임(2) 돌출 높이로 인하여 보행시 걸려 넘어지는 등의 지장을 주게 된다.In this case, the lower door frame frame (2) protruding height from the bottom surface is hindered, such as tripping when walking.

또, 각종 가구나 사물을 밀어서 이동시키거나 할 때 걸리적 거리게 된다.In addition, various furniture and objects are pushed and moved.

그리고, 가장 큰 문제점은 큰 돌출 높이로 인하여 미감을 해치는 단점이 있었던 것이다.And, the biggest problem was that there was a disadvantage to hurt the aesthetics due to the large protrusion height.

본 발명은 상기와 같은 문제점을 해소하여 바닥면에 위치되는 문틀프레임을 돌출시키지 않고도 가스켓 씰링이 이루어 질 수 있는 방화문을 제공하는 데 그 목적이 있다The object of the present invention is to provide a fire door that can be gasket sealing without solving the above problems without protruding the door frame frame located on the bottom surface.

본 발명의 다른 목적은, 자동으로 별도의 동력없이 가스켓이 승강되도록 하여 타 부품과의 간섭 없이 문을 개폐시킬 수 있고, 씰링효과가 우수한 방화문을 제공하는 데 그 목적이 있다It is another object of the present invention to automatically open and close the door without interference with other parts without additional power, and to provide a fire door with excellent sealing effect.

본 발명의 또 다른 목적은 상품성을 크게 향상시킬 수 있도록 한 방화문을 제공하는 데 있다.

이하, 본 발명의 바람직한 실시 예를 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.

본 발명은 상기 방화문(1)은 주로 일정두께의 철판을 속이 빈 상태로 절곡하여 전체적으로 문짝 형상을 갖도록 성형하게 된다.In the present invention, the fire door (1) is mainly bent in a hollow state of the iron plate of a certain thickness to be molded to have an overall door shape.

그리고, 방화문(1)의 내부 공간으로는 허니컴을 포함한 단열재를 채우게 된다.The interior space of the fire door 1 is filled with a heat insulating material including a honeycomb.

이와 같은 구조로 된 방화문(1)은 실외와 실내가 서로 열전달 되는 것을 차단할 수가 있다.The fire door 1 having such a structure can block the heat transfer between the outdoor and the indoor.

한편, 문틀프레임(2)은 시공상태에서 건축물의 벽면에 고정 설치된다.On the other hand, the door frame frame 2 is fixed to the wall surface of the building in the construction state.

이 문틀프레임(2)은 방화문(1)이 힌지(5)에 의해 개폐 가능한 상태로 양측과 상, 하 둘레를 각각 감싸지게 벽체에 고정되도록 시공되는데, 방화문(1)과 하부측 문틀프레임(2) 사이로 기밀 유지를 위해 가스켓(3)이 설치된다.The door frame frame (2) is constructed so that the fire door (1) can be opened and closed by the hinge (5) to be fixed to the wall wrapped around both sides, upper and lower circumference, respectively, the fire door (1) and lower door frame frame (2) The gasket 3 is installed to keep the airtight between

본 발명에서는 가스켓(3)을 상하 오토로 작동시키기 위하여 방화문(1)의 하부를 트여지게 하여 하우징(10)과 작동체(20), 탄성와이어(40)와 가스켓(3) 등을 장치하게 된다.In the present invention, the lower portion of the fire door (1) is opened to operate the gasket (3) up and down auto to install the housing 10, the actuator 20, the elastic wire 40 and the gasket (3) and the like. .

하우징(10)은 하부가 트여진 상태로 방화문(1)의 하단 내측으로 용접이나 비스에 의해 고정된다.The housing 10 is fixed to the inside of the lower end of the fire door 1 by welding or a screw with the lower part opened.

하우징(10)은 일정두께의 철판을 절곡하여 대략 방화문(1)의 폭에 해당되는 길이로 설계된다.The housing 10 is designed to have a length corresponding to the width of the fire door 1 by bending a steel plate of a predetermined thickness.

이 하우징(10)의 트여진 개구부로는 작동체(20)가 상하 슬라이드 가능하게 끼워 조립된다.The opener of the housing 10 is assembled with the actuator 20 slidably up and down.

작동체(20) 또한 일정두께의 철판으로 대략 하우징(10)의 길이와 대등한 길이로 수용홈(21)을 갖도록 절곡 성형하게 된다.The actuator 20 is also bent and formed to have a receiving groove 21 to a length approximately equal to the length of the housing 10 by a steel plate of a certain thickness.

수용홈(21)은 도 5에서와 같이 작동체(20)의 중앙 하부로 트여진 상태로 가스켓(3)이 끼워져 수용되는데, 가스켓(3) 양측에 다수개 형성된 날개의 탄성에 의해 이탈되지 않고 설치 상태를 유지하게 된다.The receiving groove 21 is accommodated in the gasket 3 is inserted into the center lower portion of the actuator 20 as shown in Figure 5, without being separated by the elasticity of the plurality of wings formed on both sides of the gasket (3). The installation state will be maintained.

그리고, 작동체(20)의 폭은 하우징(10)의 내측 폭보다 약간 작게 설계하여 상하 승하강이 자유롭게 제작한다.Then, the width of the actuator 20 is designed to be slightly smaller than the inner width of the housing 10 to freely move up and down.

한편, 이 작동체(20)와 가스켓(3)을 상하 자동으로 작동시키기 위하여 보턴부재(30)와 탄성와이어(40)를 지지하고 안내하기 위한 가이드(31)와 고정홀더(41)를 하우징(10)의 내측 상단 양측에 각각 고정시키게 된다.Meanwhile, in order to operate the actuator 20 and the gasket 3 automatically up and down, a guide 31 and a fixing holder 41 for supporting and guiding the button member 30 and the elastic wire 40 are provided in the housing ( 10) are fixed to both inner upper sides.

가이드(31)는 힌지(5)가 설치되는 방향으로 하우징(10)의 하부에 고정되어 보턴부재(30)의 좌우 슬라이드를 안내하게 된다.The guide 31 is fixed to the lower portion of the housing 10 in the direction in which the hinge 5 is installed to guide the left and right slides of the button member 30.

따라서, 힌지(5)를 축으로 방화문(1)이 개폐되는 과정에서 닫혀진 상태에서는 측면에 세워지는 문틀프레임(2)에 의해 보턴부재(30)가 접촉되면서 눌러져 고정홀더(41)를 향해 보턴부재(30)가 이동될 수 있도록 외력을 가하게 된다.Therefore, in the closed state in the process of opening and closing the fire door 1 with the hinge 5 as the axis, the button member 30 is pressed while contacting the button member 30 by the door frame frame erected on the side, and the button member toward the fixing holder 41. External force is applied so that the 30 can be moved.

이 보턴부재(30)와 고정홀더(41) 사이에는 탄성와이어(40)가 연결되어 있다.An elastic wire 40 is connected between the button member 30 and the fixed holder 41.

고정홀더(41)는 탄성와이어(40)의 끝단부가 일부 내측으로 수용된 상태로 하우징(10)의 타측 저면부에 고정되어 탄성와이어(40)의 끝단이 유동되지 못하도록 고정하는 역할을 수행한다.The fixing holder 41 is fixed to the other bottom surface of the housing 10 in a state where the end portion of the elastic wire 40 is partially received inward, thereby fixing the end of the elastic wire 40 not to flow.

탄성와이어(40)는 스프링강과 같이 탄성이 우수하고, 가늘고 긴 철사로 제작되어 보턴부재(30)와 고정홀더(41) 사이를 연결하고 있다.Elastic wire 40 is excellent in elasticity, such as spring steel, is made of a long thin wire is connected between the button member 30 and the fixed holder 41.

탄성와이어(40)에 외력이 가해지지 않은 자연상태에서는 일직선을 유지하고, 고정홀더(41)에 의해 단부가 고정된 상태에서 보턴부재(30)가 슬라이드 이동되면 휘어지면서 변형이 발생된다.In the natural state in which the external force is not applied to the elastic wire 40, the straight line is maintained, and the button member 30 slides in a state where the end is fixed by the fixing holder 41, causing bending and deformation.

이러한 탄성 변형을 이용하여 탄성와이어(40)의 중간부를 안내부재(50)에 관통시키고, 이 안내부재(50)를 작동체(20)의 상부에 고정시키는 것에 의해 가스켓(3)을 수용하고 있는 작동체(20)가 하강되도록 하는 것이다.By using such elastic deformation, the intermediate portion of the elastic wire 40 is penetrated through the guide member 50, and the gasket 3 is accommodated by fixing the guide member 50 on the upper portion of the actuator 20. The actuator 20 is to be lowered.

방화문(1)의 하단부에 가이드(31)에 안내되도록 끼워지는 보턴부재(30)는 탄성와이어(40)의 탄성에 의해 외력이 가해지지 않는 상태, 즉 방화문(1)이 힌지(5)에 의해 개방되어 측면에 세워지는 문틀프레임(2)과 접촉이 떨어지게 되면 탄성와이어(40)가 자연상태로 일직선을 유지하려는 탄성력이 작용되어 대략 중앙부에 끼워진 안내부재(50)가 작동체(20)와 함께 상승된다.The button member 30 fitted to the guide 31 at the lower end of the fire door 1 is in a state in which no external force is applied by the elasticity of the elastic wire 40, that is, the fire door 1 is hinged by the hinge 5. When the contact with the door frame frame 2 is opened to the side is dropped, the elastic wire 40 is applied to the elastic force to maintain a straight line in a natural state, the guide member 50 is inserted into the center portion with the actuator 20 Is raised.

이 경우 도 3에서와 같이 하우징(10)의 내측을 따라 작동체(20)가 가스켓(3)과 함께 상승되어 바닥면이나 바닥면에 횡으로 가로 질러 설치되는 문틀프레임(2)과 거리를 유지한 상태로 원활하게 방화문(1)이 개폐 작동될 수 있도록 하는 것이다.In this case, as shown in FIG. 3, the actuator 20 is raised together with the gasket 3 along the inner side of the housing 10 to maintain a distance from the door frame frame 2 installed transversely to the bottom surface or the bottom surface. The fire door 1 is to be opened and closed smoothly in one state.

이 상태에서, 방화문(1)을 닫아서 실내, 외를 차단하는 경우 방화문(1)의 측면 하단에 탄성와이어(40)의 탄성력으로 일부 돌출된 보턴부재(30)가 측면에 세워지는 문틀프레임(2)과 접촉되면서 눌러지게 된다.In this state, when closing the fire door (1) to block the interior and exterior, the door frame frame (2) in which the protruding button member 30 is erected on the side by the elastic force of the elastic wire (40) on the lower side of the fire door (1) Is pressed in contact with

보턴부재(30)는 가이드(31)의 안내로 고정홀더(41)를 향해 이동되면 그 사이를 연결하고 있던 탄성와이어(40)가 도 4에서와 같이 휘어질 수 밖에 없다.When the button member 30 is moved toward the fixing holder 41 by the guide of the guide 31, the elastic wire 40 connected therebetween is inevitably bent as shown in FIG.

따라서, 탄성와이어(40)의 중앙부에 끼워진 안내부재(50)가 작동체(20)의 상부에 고정된 상태로 하강시키는 결과로 수용홈(21)에 끼워진 가스켓(3)이 바닥 문틀프레임(2)과 접촉되면서 약간 압착상태를 유지하여, 바닥틈새를 가스켓(3)으로 완전하게 차단하게 된다.Therefore, the gasket 3 fitted in the receiving groove 21 is lowered in the bottom door frame frame 2 as a result of lowering the guide member 50 fitted in the center portion of the elastic wire 40 fixed to the upper portion of the actuator 20. ) And slightly compressed state in contact with the bottom, thereby completely blocking the bottom gap with the gasket (3).

그리고, 방화문(1)이 개방되는 순간 보턴부재(30)를 누르던 외력이 제거되므로 다시 탄성와이어(40)의 일직선을 유지하려는 탄성으로 작동체(20)와 가스켓(3)이 상승되는 작동을 반복하게 되는 것이다.In addition, since the external force that presses the button member 30 is removed at the moment when the fire door 1 is opened, the operation of the actuator 20 and the gasket 3 is lifted to the elasticity to maintain the straight line of the elastic wire 40 again. It will be repeated.

한편, 하우징(10)에는 작동체(20)의 상승 범위를 제한하기 위해 내측으로 길이 방향을 따라 걸림턱(11)이 성형된다.
On the other hand, the locking jaw 11 is formed in the housing 10 along the longitudinal direction in order to limit the rising range of the actuator 20.
