본 고안은 건물내부에서 화재가 일어났을 때 한 구획에서 발생한 연기나 불길이 다른 구획으로 번지는 것을 미연에 방지하기 위해 설치되는 방화문의 자석식 자동폐쇄장치에 관한 것이다.The present invention relates to a magnetic automatic closing device of a fire door that is installed to prevent smoke or flames generated in one compartment from spreading to another compartment when a fire occurs inside a building.

일반적으로 건물내에 방화문을 설치하여야 하는 까닭은, 대형빌딩의 경우 화제가 일어났을 때 한 구획에서 다른 구역으로 연기나 불길이 번지게 되면 작은 규모의 화재가 대형화재로 변모케될 위험이 크고 특히 유독성 연기의 확산으로 화재현장에 있던 사람이 질식사할 우려도 있기 때문인 것이다.In general, it is necessary to install fire doors in a large building. In case of a large building, if a fire or smoke spreads from one compartment to another when a fire breaks out, there is a high risk of a small fire becoming a large fire, especially toxic. This is because there is a risk that people at the scene of fire may choke due to the spread of smoke.

그러므로 정부에서 규정한 건축물에 대한 건축법 및 소방법에 따르면 비교적 대형인 건축물에는 일정한 구획마다 도어체크(DOOR CHECK)를 구비하고 철판으로 된 갑종 방화문을 설치하여야 한다고 명시하고 있다.Therefore, according to the government's building and fire laws for buildings, the relatively large buildings must be equipped with door checks in certain sections and installed first grade fire doors made of steel plates.

이러한 이유로 종래에도 일정규모이상의 건축물에는 통상의 출입문에 철제 방화문을 겸설하여 평상시에는 상기 방화문을 벽쪽에 고정하고 있다가 화재시에 별도의 화재감지신호에 의래 철제 방화문이 자동으로 닫혀지게 하기 위한 전자석을 이용한 방화문 스톱장치 (일본 공개실용 신안공보 실개소 49-106136참조)가 안출된바 있으나, 이는 방화문에 계지돌기를 형성하고 벽쪽에는 랫치레바를 설치하여 화재발발시 화재감지신호에 의해 전자석이 랫치레바를 잡아당겨 방화문이 자동으로 닫혀지게 한 것으로 다음과 같은 결점이 있었다. 즉, 방화문에 형성한 계지돌기와 랫치레바의 위치가 조금이라도 변위되면 괘지불량이 발생하기 쉽고, 방화문이 벽에 접촉될때 벽면과 방화문사이에 거의 평행을 이루지 않으면 괘지불량이 생기며, 구성 부품이 너무 많아 제작이 까다롭고 마모부분이 발생하여 고장이 잦고 수명이 짧은 것등의 결점이 있었다.For this reason, conventionally, a building with a certain size or more is equipped with an iron fire door to a normal entrance door, and the fire door is fixed to the wall at ordinary times, and in case of fire, an electromagnet for automatically closing the steel fire door due to a separate fire detection signal. The fire door stop device used (see Shin-A-Kan publication No. 49-106136) has been conceived, but it has a latching protrusion on the fire door and a latch lever on the wall. The fire door was automatically closed by pulling the tire bar, which had the following drawbacks. In other words, if the position of the locking projection and the latch lever formed on the fire door is displaced even a little, it is easy to cause misalignment, and when the fire door is in contact with the wall, the misalignment between the wall surface and the fire door occurs, causing misalignment. Many of them are difficult to manufacture and wear parts are generated, resulting in frequent breakdowns and short lifespans.

본 고안은 종래의 이러한 결점을 해소하기 위하여 종래와 같이 계지돌기와 이 돌기를 잡아주는 랫치를 사용하지 않고 방화문쪽에는 넓다란 평판으로 된 고정판을 붙이고 벽쪽에는 평판을 잡아주는 영구자석을 설치하여 이 영구자석이 항시 동일한 힘으로 방문을 잡아주도록 하고 이 영구자석의 자력을 화재시 화재 감지신호에 의해 상쇄시켜 주도록 전자석을 영구자석과 병설하여서 된 것으로, 종래와 같은 작동불량, 제작상 난점, 설치위치 정확도의 필요성, 수명단축 요인들의 문제점을 제거한 것이다.The present invention does not use the locking projection and the latch to hold the projection as in the prior art in order to solve the above-mentioned defects, and attaches a fixed plate of a wide flat plate on the fire door and a permanent magnet to hold the flat plate on the wall. The magnet is connected to the permanent magnet so that the magnet always catches the visit with the same force and the magnetic force of the permanent magnet is canceled by the fire detection signal in case of fire. This eliminates the problem of necessity and shortening factors.

이를 도면에 의거하여 상세히 설명하면 다음과 같다.This will be described in detail with reference to the drawings as follows.

전체적으로 본 고안은 도어체크(2)를 가진 방화문(1)의 외벽일측에 자석에 잘붙는 철제 흡착고정판(3)을 부착하고 이 방화문(1)의 맞은편 벽면에는 상기 흡착고정판(1)과 대응하는 위치에 자력을 가진 자석폐쇄기(4)를 설치하되 상기 자석폐쇄기(4)는 화재가 났을때 연기를 감지토록한 센서(5) 및 제어반(6)과 연계작동하여 자력을 상실토록 되어 있다.In general, the present invention attaches an iron adsorption fixing plate 3 that adheres well to a magnet to one side of an outer wall of the fire door 1 having a door check 2, and corresponds to the adsorption fixing plate 1 on a wall opposite to the fire door 1. The magnetic closure 4 having magnetic force is installed at the position of the magnetic closure 4, but the magnetic closure 4 is operated in conjunction with the sensor 5 and the control panel 6 to detect smoke when a fire occurs, thereby losing the magnetic force.

상기 자석폐쇄기(4)는, 중앙에 탄지봉(7)이 출입하도록 통공이 형성된 자석케이스(8)내부에 환상의 영구자석(9) 및 전자석(10)을 차례로 수장하되 이들 영구자석(9)과 전자석(10)사이에 흡착면(11'')을 가진 환봉(11')을 중앙에 입설한 자성판(11)을 게재시키고, 상기 자석케이스(8)를, 하단중앙에 지지봉(12)을 가진 비자성체 함체(13)내에 적당한 깊이로 몰입하여 설치하되 상기 탄지봉(7) 및 지지봉(12)사이에 스프링(14)을 탄설함과 동시에 탄지봉(7) 일측으로 연설한 편스프링(15)을 자석케이스(8) 및 함체 (13)사이에 설치한 기판(16)상의 스위치(17)에 이와 연동토록 접설하여, 상기 함체(13)의 중앙외측으로 인출한 지지봉(12)의 연장부에는 보울트(12')를 형성하여, 이를 지지판(18)에 너트로써 고정하되, 상기 지지판(18)과 지지봉(12)하단의 걸림턱(12'')사이에 스프링(19)을 탄설하고, 상기 지지판(18)은 이의 사방지지각(18')을 벽면에 부착되는 전면판(20) 내측의 조절보울트(21)상에 설치하여 고정하며, 그 내벽일단에 함체(13)의 걸림편(13')과 부합하여 상기 함체(13)가 임의로 회동됨을 방지하는 걸림턱(18'')이 형성되어 있다.The magnetic closure (4), the permanent magnet (9) and the electromagnet (10) of the annular permanent magnets (9) and the electromagnet (10) in the inside of the magnet case (8) formed in the through hole to enter and exit the center, the permanent magnets (9) A magnetic plate 11 having a circular rod 11 ′ having a suction surface 11 ″ placed therebetween in the center and the electromagnet 10. The magnet case 8 is placed at the bottom of the support rod 12. One side spring immersed and installed at a suitable depth in the nonmagnetic material body 13 having a spring 14 between the carbon rods 7 and the support rods 12 and simultaneously speaking to one side of the carbon rods 7 15 is connected to the switch 17 on the substrate 16 provided between the magnet case 8 and the housing 13 so as to be interlocked with the switch 17, and the support rod 12 extended to the outside of the center of the housing 13 is extended. A bolt 12 'is formed in the part, and the nut is fixed to the support plate 18 by a nut, and a spring 19 is disposed between the support plate 18 and the locking jaw 12' 'at the lower end of the support rod 12. And the support plate 18 is installed and fixed on the control bolt 21 inside the front plate 20 attached to the wall surface thereof, and the support plate 18 is fixed to the wall 13 at one end of the inner wall thereof. In accordance with the piece 13 ', a locking step 18' 'is formed to prevent the enclosure 13 from being rotated arbitrarily.

이와 같이 구성되는 자석폐쇄기(4)에 있어서 상기 전자석(10)은 평상시에는 작동되지 않다가 화재발생시 연기를 감지한 센서(5) 및 제어반(6)에 의해 통전됨으로써 자성을 띠게 되는데 그 자력이 영구자석(9)의 자력과 상쇄되어 흡착면(11'')의 자력이 없어지게 되며, 스위치(17)는 도면 제2도와 같은 상태에서 접속되어 부자(22)를 작동시켜 줌으로써 소기의 비상경보음을 발생토록 되어 있다.In the magnetic closure device 4 configured as described above, the electromagnet 10 is not normally operated, but becomes energized by the sensor 5 and the control panel 6 which detect smoke when a fire occurs. The magnetic force is permanent. The magnetic force of the magnet 9 is canceled to cancel the magnetic force of the suction surface 11 ″, and the switch 17 is connected in the state shown in FIG. 2 to operate the rich 22, thereby providing a desired emergency alarm sound. It is supposed to occur.

미설명부호 23은 다이오드소자, 24는 내측고정판, 25는 고정나사, 26은 상기 전자석(10)의 전원스위치, a와 a1,b,b1은 단자이다.Reference numeral 23 is a diode element, 24 is an inner fixing plate, 25 is a fixing screw, 26 is a power switch of the electromagnet 10, a and a 1 , b, b 1 are terminals.

이러한 구조의 본 고안은, 평상시에는 문에 설치된 흡착고정판(3)을 영구자석(9)의 자력에 의해 도어체크(2)의 닫음력보다 더 강력한 자력을 띤 자석폐쇄기(4)의 흡착면(11'')에 붙여둠으로써 방화문(1)을 상시 열어놓게 되는데, 이때 상기 흡착고정판(3)이 흡착면(11'')에 부착됨에 따라 탄지봉(7)을 후퇴시켜 주게되므로 상기 탄지봉(7)의 편스프링(15)이 스위치(17)로 하여금 OFF된 상태로 있게함으로써 비상경보음을 발하는 부자(22)가 작동되지 않음과 동시에 전자석(10)을 작동시켜 주는 스위치(26)도 OFF된 상태로 있어 전자석(10)이 자력을 띠지 않게 된다.According to the present invention of the structure, the adsorption surface of the magnetic closure device 4 having a magnetic force stronger than the closing force of the door check 2 by the magnetic force of the permanent magnet 9 is normally attached to the adsorption fixing plate 3 installed on the door. 11 '') to open the fire door (1) at all times, the retaliating plate (3) is attached to the adsorption surface (11 ''), so as to retreat the tanji rod (7), the tanji rod The switch 26 which activates the electromagnet 10 at the same time that the rich spring 22 of (7) causes the switch 17 to be in the OFF state does not operate the rich 22 that emits an alarm sound. In the OFF state, the electromagnet 10 is not subjected to magnetic force.

이와 같은 평시상태에서 만일 화재가 발생하면 연기를 감지한 센서(5) 및 제어반(6)이 작동스위치(26)을 ON시켜서 상기 전자석(10)에 통전케 되고, 이와 동시에 전자석(10)은 자력을 띠어서 그 자력이 영구자석(9)의 자력과 상쇄됨으로써 방화문(1)의 흡착고정판(3)을 잡아당기고 있던 흡착면(11'')의 자력이 상실되며, 이때에는 도어체크(2)의 닫음력이 상기 흡착면(11'')의 자력을 이기게 되므로 이 도어체크(2)가 방화문(1)을 자동적으로 닫아서 폐쇄시켜 주게 된다.If a fire occurs in such a normal state, the sensor 5 and the control panel 6 which detect the smoke turn on the operation switch 26 to energize the electromagnet 10, and at the same time, the electromagnet 10 As the magnetic force is canceled by the magnetic force of the permanent magnet 9, the magnetic force of the suction surface 11 '', which was pulling the suction fixing plate 3 of the fire door 1, is lost, and at this time, the door check 2 Since the closing force of the overtakes the magnetic force of the suction surface 11 '', the door check 2 automatically closes and closes the fire door 1.

또한 이와 같은 방화문(1)이 닫힐때 흡착면(11'')으로부터 흡착고정판(3)이 해방되어 떨어짐에 따라 탄지봉(7)이 스프링(14)의 힘으로 원위치하게 되므로 이의 편스프링(15)이 스위치(17)을 ON시켜서 부자(22)에 통전케 되므로 소기의 비상경보음을 발하게 되는 것이다.In addition, when the fire door 1 is closed, as the adsorption fixing plate 3 is released from the adsorption surface 11 '' and falls off, the carbon rod 7 is returned to its original position by the force of the spring 14, so that the spun spring 15 ) Turns on the switch 17 to energize the rich 22 is to emit a desired emergency alarm sound.

함체(13)를 지지봉(12) 및 스프링(19)으로써 지지판(18)에 유착시켜둠은 방화문(1)과 자석폐쇄기(4)의 설치각에 따라 흡착고정판(3)이 흡착면(11'')에 항상 거의 완전한 수평상태로 부착되게 하기 위함이고, 벽면에 부착되는 전면판(20)에 대한 자석케이스(8) 및 함체(13)의 노출정도는 상기 전면판(20) 내측의 조절보울트(21)를 돌려서 지지판(18)을 후퇴, 또는 전진시켜 줌으로써 적절히 조절할 수 있도록 하였으며, 상기 함체(13) 및 지지판(18)에 각각 서로 부합되는 걸림편(13')과 걸림턱(18'')을 형성한 것은 함체(13)가 지지봉(12)을 중심으로 임의로 회동됨을 방지하기 위한 것이다.The adsorption fixing plate 3 has an adsorptive surface 11 'according to the installation angles of the fire door 1 and the magnetic closure device 4, in which the housing 13 is bonded to the support plate 18 by the support rod 12 and the spring 19. ') Is always attached to the almost complete horizontal state, and the degree of exposure of the magnet case 8 and the housing 13 to the front plate 20 attached to the wall is the control bolt inside the front plate 20 (21) by turning the support plate (18) to retract or advance, so that it can be adjusted appropriately, and the locking piece (13 ') and the locking step (18' ') corresponding to each of the housing 13 and the support plate (18), respectively Is formed to prevent the housing 13 from being arbitrarily rotated around the support rod 12.

이상에서 설명한 바와 같이 본 고안은 화재가 났을때 방화문을 자동적으로 닫아서 폐쇄시켜 주는 자동폐쇄장치로서, 종래의 자동폐쇄장치에 비하여 구조가 간단하여 제작이 편리하고, 계지돌기와 랫치의 결합방법이 아니고 평판으로 된 흡착고정판과 영구자석에 의한 결합방법을 사용함으로써 사용중 방화문이 어느정도 변위되더라도 작동불량이 생기지 않으며 설치위치가 종전처럼 정밀할 필요가 없어 설치가 용이하고 함체가 흡착고정판의 면에 항시 대응해서 움직여 주므로 방화문의 열림각도의 허용범위도 넓어졌으며, 마모부분이 없으므로 수명이 장구한 것등의 특징을 지닌 것이다.As described above, the present invention is an automatic closing device that automatically closes and closes the fire door in the event of a fire. The structure is simpler than the conventional automatic closing device, and is easy to manufacture. By using the combination method of adsorption fixing plate made of permanent magnet and permanent magnet, no malfunction occurs even if the fire door is displaced to some extent during use, and the installation position does not need to be precise as before, so the installation is easy and the enclosure always moves in response to the surface of the adsorption fixing plate. As a result, the allowable range of the opening angle of the fire door has been widened, and because it has no wear parts, it has a long service life.
