본 고안은 공동주택의 부속실에 설치되어 화재시 외부공기를 부속실로 안내하는 제연설비의 급기댐퍼에 관한 것으로, 두 판재가 슬립에 의해 개구부가 개폐되도록 하여 두깨를 얇게 형성하는 것이 가능하도록 하므로 공기의 유동성이 향상되도록 하고, 그 제작비용이 저감되도록 하는 것이다.The present invention relates to an air supply damper of a ventilation device that is installed in an accessory room of an apartment house and guides external air to an accessory room in case of fire. The two plates allow the opening to be opened and closed by slip so that the thickness of the air can be formed thinly. It is to improve the fluidity and to reduce the production cost.

일반적으로 공동주택은 소화활동을 위한 부속실이 양쪽 주거공간 사이에 형성되고, 상기 부속실의 전방이 방화문을 통하여 상하층의 피난계단과 연결되며, 상기 부속실 후방에 엘리베이터이동공간이 상하로 연장 형성되어 있다. 또한, 부속실의 전방 일측에 공동구가 건축물의 상하로 수직풍도를 이루며 연통되게 형성되어 화재시 부속실로 외부공기를 공급시키기 위한 제연설비가 공동구와 연통되게 장치되며, 상기 부속실의 전방과 피난계단 사이에 방화문이 개폐 가능하게 설치되어 현관문과 방화문을 닫으면 부속실이 공동구의 내부와만 통공 가능한 소정의 안전지역이 되도록 되어 있다.In general, an apartment house for fire extinguishing activities is formed between two living spaces, and the front of the auxiliary room is connected to an evacuation stairway on the upper and lower floors through a fire door, and an elevator moving space extends up and down behind the accessory room. . In addition, the cavity is formed on the front side of the annex to communicate vertically up and down the building and the ventilation equipment for supplying external air to the accessory room in the event of a fire is installed in communication with the cavity, between the front and the evacuation stairs of the annex. When the fire door is opened and closed, the entrance door and the fire door are closed so that the attached room becomes a predetermined safety area that can only be penetrated through the interior of the common area.

여기에서, 제연설비는 도 1과 도 2에 도시되는 바와 같이, 공동주택의 옥상에 송풍기(20)와 급기덕트(40)가 서로 연통되게 설치되고, 급기덕트(40)의 후단부가 상기 공동주택 각층의 부속실과 연통되는 수직풍도(30)에 연통되어 있다. 또한, 수직풍도(30)의 상단부에 제1풍량조절댐퍼(51)가 개폐 가능하게 장치되고, 급기덕트(40)의 후단부에 제1풍량조절댐퍼(51)와 반비례로 자동제어되는 제2풍량조절댐퍼(52)가 개폐 가능하게 장치되어 있다. 또한, 수직풍도(30)의 하부에 수직풍도(30) 하부의 압력을 감지하는 차압센서(71)가 장착되고, 각 거주공간에 연기 발생을 감지하는 연기감지기(72)가 장착되며, 차압센서(71)와 연기감지기(72)의 감지상태가 각기 전기적인 신호로 방재반(70)의 제어장치(73)에 인가되도록 통전 가능하게 연결되어, 상기 제어장치(73)가 인가 받은 신호를 연산하여 판단에 따라 제어신호를 송풍기(20)와 제1풍량조절댐퍼(51) 및 제2풍량조절댐퍼(52)에 자동으로 출력하여 제어하도록 연결된다.1 and 2, the ventilation device is installed on the roof of the multi-unit house so that the blower 20 and the air supply duct 40 communicate with each other, and the rear end of the air supply duct 40 is installed in the multi-unit house. It communicates with the vertical winds 30 which communicate with the attached rooms of each floor. In addition, the first air volume control damper 51 is provided to open and close at the upper end of the vertical air flow 30, and the second air volume is automatically controlled in inverse proportion to the first air volume control damper 51 at the rear end of the air supply duct 40. The air volume control damper 52 is provided to be opened and closed. In addition, the differential pressure sensor 71 for detecting the pressure of the lower vertical wind (30) is mounted on the lower portion of the vertical wind (30), smoke detector 72 for detecting the occurrence of smoke in each living space is mounted, the differential pressure sensor The sensing state of the 71 and the smoke detector 72 are electrically connected to each other so as to be applied to the control device 73 of the disaster prevention panel 70 as an electrical signal, thereby calculating a signal applied by the control device 73. The control signal is connected to the blower 20, the first air volume control damper 51 and the second air volume control damper 52 to be automatically controlled according to the judgment.

이와 같이 구성되는 제연설비는 화재발생으로 인해 연기감지기(72)에 연기발생이 감지되면 그 감지신호를 제어장치(73)에 인가하고, 그 감지신호를 인가 받은 제어장치(73)가 송풍기(20)와 제1풍량조절댐퍼(51) 및 제2풍량조절댐퍼(52)의 구동모터에 전원을 인가하여 송풍기(20)가 급기덕트(40)로 외부공기를 송풍하고 제1풍량조절댐퍼(51)와 제2풍량조절댐퍼(52)를 선택적 개도율로 열도록 제어하므로, 외부공기가 수직풍도(30)를 통해 각층의 부속실로 압송되도록 한다.When the smoke is detected by the smoke detector 72 due to the fire, the smoke control device configured as described above applies the detection signal to the control device 73, and the control device 73 receiving the detection signal is blower 20. ) And the driving motors of the first air volume control damper 51 and the second air volume control damper 52 to blow the external air to the air supply duct 40, and the first air volume control damper 51. ) And the second air volume control damper 52 to be opened to the selective opening rate, so that the outside air is pumped to the attached room of each floor through the vertical wind (30).

한편, 각층의 부속실에는 도 2와 도 3에 도시되는 바와 같이, 수직풍도(30)에 개구부가 형성되어 상기 개구부에 급기댐퍼(56)가 설치되고, 급기댐퍼(56)의 전면에 그릴이 형성되는 루버(54)의 외곽부가 결합되어 있다.Meanwhile, as shown in FIGS. 2 and 3, an opening is formed in the vertical wind turbine 30, and an air supply damper 56 is installed in the opening, and a grill is formed on the front side of the air supply damper 56. The outer portion of the louver 54 is coupled.

또한, 급기댐퍼(56)는 상부에 핸들(55)이 장치되는 조작반이 형성되고, 하부에 개방부가 형성되어, 상기 개방부에 복수개의 회전축(57)이 각기 핸들(55)에 의해 동시에 회전조작이 가능하도록 일정 간격을 두고 지지되고, 상기 각 회전축(57)에 상기 개방부를 개폐하는 날개(53)들이 일체로 움직이도록 결합되어 있다.In addition, the air supply damper 56 has an operating panel on which a handle 55 is mounted, and an opening is formed at a lower portion thereof, and a plurality of rotation shafts 57 are simultaneously rotated by the handle 55 at the opening. It is supported at a predetermined interval so as to enable, and the wings (53) for opening and closing the opening to each of the rotary shafts 57 are coupled to move integrally.

이러한 제연설비는 평상시 각층의 급기댐퍼 날개(53)가 일정 개도율의 열린 상태로 있고, 제1풍량조절댐퍼(51) 및 제2풍량조절댐퍼(52)가 수직풍도(30)의 상부 및 배출구를 완전히 폐쇄시켜 각층의 수직풍도(30) 개구부가 외부와 차단된 상태로있게 되어, 제1풍량조절댐퍼(51)만 열면 각층의 급기댐퍼가 송풍기(20)를 통해 급기되는 외부공기에 연통되게 된다.In such a ventilation system, the air supply damper blades 53 of each floor are normally opened at a constant opening rate, and the first air volume control damper 51 and the second air volume control damper 52 are upper portions of the vertical air wind 30 and the outlets. To completely close the openings of the vertical winds 30 of each floor to be in a state of being cut off from the outside, so that only the first air volume control damper 51 is opened so that the air supply dampers of each floor communicate with the outside air supplied through the blower 20. do.

그러나 이러한 제연설비의 급기댐퍼는 복수개의 회전축(57)에 각기 날개(53)가 결합되어 회전에 의해 개구부를 개폐하도록 되어 있기 때문에, 그 구조가 복잡하여 제작비용이 상승되고, 급기댐퍼(56)의 두께가 비교적 두껍게 되어 수직풍도(30)의 내부로 돌출되는 부분이 많아 공기의 유동성이 좋지 않은 문제점이 있었다.However, since the air supply dampers of the smoke control system are respectively coupled to the plurality of rotary shafts 57 and the blades 53 are opened and closed by rotation, the structure is complicated and the manufacturing cost is increased, and the air supply dampers 56 are provided. Since the thickness of the relatively thick portion protruding into the interior of the vertical wind (30), there was a problem that the air flowability is not good.

본 고안은 상기와 같은 문제점들을 해소하기 위해 고안한 것으로, 일정 간격으로 개구부가 형성되는 두개의 판재가 서로 슬립 가능하게 결합되는 것에 의해 급기댐퍼가 형성되고, 이러한 급기댐퍼가 수직풍도의 개구부에 설치되어, 수직풍도 내부로 돌출되는 부분이 좁도록 하므로 공기의 유동성이 향상되도록 하는데 그 목적이 있다.The present invention has been devised to solve the above problems, the air supply damper is formed by the two plate members which are formed at a predetermined interval so that the opening is slipably coupled to each other, the air supply damper is installed in the opening of the vertical wind In order to narrow the portion projecting into the vertical wind, the purpose of the air flow is to be improved.
