화재 확산 방지용 수동방화유리문{fireproof glass door for preventing fire spread}Manual fireproof glass door for preventing fire spread}

본 발명은 수동방화유리문에 관한 것으로, 보다 구체적으로 화재발생시 스프링클러를 통해 공급되는 물의 수압을 이용하여 도어패널을 자동으로 회동시켜 닫음으로써 도어패널이 열려서 화재가 확산되는 것을 효과적으로 방지할 수 있는 새로운 구조의 화재 확산 방지용 수동방화유리문에 관한 것이다.The present invention relates to a passive fire glass door, and more particularly, to a new structure capable of effectively preventing the spread of fire due to the opening of the door panel by automatically rotating and closing the door panel using water pressure supplied through a sprinkler in the event of a fire. It relates to a passive fireproof glass door for preventing the spread of fire.

통상 방화유리문은 도 1에 도시된 바와 같이 투명한 내열유리로 제작되어 평상시에는 깨끗한 시야 확보 및 개방감을 얻을 수 있을 뿐만 아니라, 화재발생시 비상대피에 따른 시야가 확보되도록 현관문, 방문등과 같은 출입구나 창문, 비상구와 같은 개구부에 여닫이문, 미닫이문, 미서기문, 접문, 회전문 등의 개폐방식으로 설치된다.In general, fireproof glass doors are made of transparent heat-resistant glass, as shown in FIG. 1, so that a clear view and a sense of openness can be obtained at ordinary times, as well as an entrance or exit such as a front door or a door to secure a view for emergency evacuation in the event of a fire. It is installed in openings such as windows and emergency exits in an opening and closing method such as a casement door, a sliding door, a sliding door, a folding door, and a revolving door.

방화유리문의 일례로 한국 등록 특허 제10-0726626호 '방화유리문의 프레임구조' 는 도 2에 도시된 바와 같이 방화유리문의 도어유리 및 픽스창유리와 같은 내열유리를 지지하도록 종횡방향으로 교차되게 설치되어 구획을 형성하도록 일면 또는 양면에 제1삽입홈(12)과 함께 한 쌍의 제1지지턱(14)을 형성하고, 상기 제1지지턱(14)은 서로 대향하는 어느 일측이 분할 제작되어 볼트(B)로 체결되는 지지프레임(10)과, 상기 지지프레임(10)의 제1삽입홈(12)에 외면이 수용된 상태로 설치되고, 내면에 제2삽입홈(22)과 함께 한 쌍의 제2지지턱(24)이 형성되어 내열유리(G)의 테두리부를 지지하는 유동프레임(20)으로 구성되는 프레임에 있어서: 상기 지지ㆍ유동프레임(10)(20)의 제1, 2삽입홈(12)(22)에 유동프레임(20) 및 내열유리(G)가 삽입된 상태로 열팽창에 따른 지지프레임(10)과 유동프레임(20)의 휨 변형을 흡수하도록 공간부(30)가 형성되는 것을 특징으로 한다.As an example of a fireproof glass door, Korea Patent Registration No. 10-0726626 'Frame structure of a fireproof glass door' is installed to cross in the vertical and horizontal directions to support heat-resistant glass such as a door glass and a fix window glass of a fireproof glass door as shown in FIG. A pair of first supporting jaws 14 are formed together with first insertion grooves 12 on one side or both sides to form a compartment, and the first supporting jaws 14 are manufactured by dividing one side facing each other with bolts. The support frame 10 fastened to (B) and the outer surface of the support frame 10 are installed in a state accommodated in the first insertion groove 12, and the pair of the pair together with the second insertion groove 22 on the inner surface In the frame composed of the floating frame 20 on which the second supporting jaw 24 is formed to support the edge of the heat-resistant glass G: the first and second insertion grooves of the supporting/moving frame 10 and 20 (12) A space portion 30 is formed to absorb bending deformation of the support frame 10 and the floating frame 20 due to thermal expansion with the floating frame 20 and the heat-resistant glass G inserted in the (22) characterized by being

이러한 특징을 갖는 방화유리문은 방화유리문을 구성하는 도어유리 및 픽스창유리의 테두리부분이 프레임상에 이격되도록 설치됨에 따라 화재발생시 프레임이 고열에 노출되어 열팽창으로 인한 변형 및 뒤틀림이 발생되더라도 신축성 및 연신율의 허용한계치가 향상되어 내열유리의 파손이 방지되는 효과가 있다.Fireproof glass doors with these characteristics are installed so that the edges of the door glass and fix window glass constituting the fireproof glass door are spaced apart from each other on the frame, so that even if the frame is exposed to high heat in the event of a fire and deformation and distortion due to thermal expansion occur, the elasticity and elongation of the door glass door There is an effect of preventing breakage of heat-resistant glass by improving the tolerance limit.

그러나, 화재 발생시 화염이 확산되는 것을 여전히 방지할 수 없는 한계가 있었다.However, there is still a limit that cannot prevent the flame from spreading in the event of a fire.

이러한 한계를 극복하고자 제안된 수동방화유리문, 보다 구체적으로 통로 등에 설치되어 화재 발생시 화염이 확산되는 것을 방지할 수 있도록 된 수동방화유리문은 도 3에 도시한 바와 같이, 도어프레임(1)과, 상기 도어프레임(1)에 전후방향으로 회동가능하게 결합된 도어패널(2)로 구성된다.A passive fire glass door proposed to overcome these limitations, more specifically, a passive fire glass door installed in a passage or the like to prevent the spread of flame in the event of a fire, as shown in FIG. 3, a door frame 1, It consists of a door panel (2) coupled to the door frame (1) to be rotatably forward and backward.

상기 도어패널(2)은 금속프레임과 내열유리로 구성된 것으로, 일측의 상하단에 구비된 회동축(2a)에 의해 상기 도어프레임(1)에 전후방향으로 회동가능하게 결합된다.The door panel 2 is composed of a metal frame and heat-resistant glass, and is rotatably coupled to the door frame 1 in the forward and backward directions by a pivot shaft 2a provided at the top and bottom of one side.

따라서, 평상시에 도어를 열어놓은 상태에서, 화재가 발생되었을 경우 상기 도어패널(2)을 닫으면, 통로가 막혀서 화재가 확산되는 것을 방지할 수 있다.Therefore, if the door panel 2 is closed when a fire occurs in a state in which the door is normally open, it is possible to prevent the fire from spreading due to the blockage of the passage.

그런데, 이러한 수동방화유리문은 화재발생시 사람이 직접 도어패널(2)을 회동시켜 닫아야 함으로, 도어패널(2)을 닫을 사람이 없을 경우, 화재가 확산되는 것을 방지할 수 없는 문제점이 있었다.However, since such a passive fire glass door requires a person to directly rotate and close the door panel 2 in the event of a fire, when there is no one to close the door panel 2, there is a problem in that the fire cannot be prevented from spreading.

따라서, 이러한 문제점을 해결할 수 있는 새로운 방법이 필요하게 되었다.Therefore, there is a need for a new method capable of solving these problems.

한편, 이러한 수동방화문이 설치되는 건축물에는 화재발생시 자동으로 작동되어 화재를 진압하는 스프링클러(3)가 구비된다.On the other hand, the building in which such a passive fire door is installed is provided with a sprinkler (3) that is automatically operated to suppress the fire when a fire occurs.

상기 스프링클러(3)는 고압의 물을 공급하는 급수관(3a)과, 상기 급수관(3a)에 구비된 복수개의 분사노즐(3b)로 구성된다.The sprinkler 3 is composed of a water supply pipe 3a supplying high-pressure water and a plurality of spray nozzles 3b provided in the water supply pipe 3a.

상기 급수관(3a)에는 항상 일정한 압력의 물이 공급된다.Water at a constant pressure is always supplied to the water supply pipe 3a.

상기 분사노즐(3b)은 일정한 온도 이상으로 가열되면 자동으로 개방되어 급수관(3a)을 통해 공급되는 고압의 물을 분사할 수 있도록 구성된다.The spray nozzle 3b is automatically opened when heated to a certain temperature or higher, and is configured to spray high-pressure water supplied through the water supply pipe 3a.

상기 승강실린더(20)는 도 6 및 도 8에 도시한 바와 같이, 상하방향으로 연장된 실린더(21)와, 상기 실린더(21)의 내부에 승강가능하게 구비되어 실린더(21)의 내부 공간을 상측의 제1 챔버(21a)와 하측의 제2 챔버(21b)로 구획하는 피스톤(22)과, 상기 피스톤(22)에서 실린더(21)의 하측으로 연장되어 상기 수압모터(10)에 연결되는 피스톤로드(23)와, 상기 제1 챔버(21a)에 구비되어 피스톤(22)을 하측으로 가압하는 탄성부재(24)와, 상기 급수관(3a)에서 분기되어 상기 제2 챔버(21b)에 연결되는 보조급수관(25)으로 구성된다.As shown in FIGS. 6 and 8, the elevating cylinder 20 is provided with a cylinder 21 extending in the vertical direction and movable inside the cylinder 21 so as to expand the inner space of the cylinder 21. A piston 22 partitioned into an upper first chamber 21a and a lower second chamber 21b, and extending from the piston 22 to the lower side of the cylinder 21 and connected to the hydraulic motor 10 A piston rod 23, an elastic member 24 provided in the first chamber 21a and pressurizing the piston 22 downward, branched from the water supply pipe 3a and connected to the second chamber 21b It consists of an auxiliary water supply pipe (25).

상기 탄성부재(24)는 상기 제1 챔버(21a)의 내부에 상하방향으로 연장된 압축코일스프링을 이용하는 것으로, 탄성이 상기 급수관(3a)을 통해 공급되는 물의 수압에 비해 낮게 설정된다.The elastic member 24 uses a compression coil spring extending vertically inside the first chamber 21a, and has elasticity lower than that of water supplied through the water supply pipe 3a.

상기 보조급수관(25)은 상기 급수관(3a)을 통해 공급되는 물의 일부가 상기 제2 챔버(21b)로 공급되도록 함으로써, 제2 챔버(21b)의 내부에 수압이 형성되도록 하고, 이와 같이 형성된 수압에 의해 피스톤(22)과 피스톤로드(23) 및 수압모터(10)가 상측으로 밀려올라가도록 한다.The auxiliary water supply pipe 25 allows a portion of the water supplied through the water supply pipe 3a to be supplied to the second chamber 21b so that water pressure is formed inside the second chamber 21b, and the water pressure thus formed As a result, the piston 22, the piston rod 23, and the hydraulic motor 10 are pushed upward.

이와 같이 구성된 수동방화유리문의 작용을 설명하면 다음과 같다.The operation of the passive fire glass door constructed as described above will be described.

우선, 화재가 발생되지 않은 상태에서는 상기 곱수관 내부의 물이 높은 압력을 유지하게 되며, 이와 같은 고압의 물이 상기 보조급수관(25)을 통해 상기 제2 챔버(21b)로 공급되어 도 5, 6 및 도 8에 도시한 바와 같이, 피스톤(22)을 상측으로 밀어낸다.First, in a state where no fire occurs, the water inside the water supply pipe maintains a high pressure, and such high-pressure water is supplied to the second chamber 21b through the auxiliary water supply pipe 25, as shown in FIG. 5, As shown in 6 and 8, the piston 22 is pushed upward.

따라서, 피스톤(22)과 피스톤로드(23) 및 수압모터(10)가 상승되어, 수압모터(10)와 회동축(2a)이 분리되어 있음으로, 사용자가 자유롭게 도어패널(2)을 회동시켜 열거나 닫을 수 있다.Therefore, the piston 22, the piston rod 23, and the hydraulic motor 10 are raised, and since the hydraulic motor 10 and the rotating shaft 2a are separated, the user can freely rotate the door panel 2. can be opened or closed.

그리고, 화재가 발생될 경우, 상기 스프링클러(3)의 분사노즐(3b)이 자동으로 개방되어 물을 분사하게 되며, 이에 따라, 상기 급수관(3a) 내부의 수압이 낮아지게 된다.Also, when a fire occurs, the spray nozzle 3b of the sprinkler 3 is automatically opened to spray water, and accordingly, the water pressure inside the water supply pipe 3a is lowered.

따라서, 상기 제2 챔버(21b) 내부의 수압이 낮아지게 되며, 이에 따라, 도 9에 도시한 바와 같이, 상기 탄성부재(24)의 탄성에 의해 피스톤(22)과 피스톤로드(23) 및 수압모터(10)가 하강되어, 수압모터(10)의 구동축(13)과 회동축(2a)이 상호 결합된다.Therefore, the water pressure inside the second chamber 21b is lowered, and accordingly, as shown in FIG. 9, the piston 22, the piston rod 23, and the water pressure due to the elasticity of the elastic member 24 The motor 10 is lowered, and the drive shaft 13 and the rotation shaft 2a of the hydraulic motor 10 are coupled to each other.

그리고, 상기 급수관(3a) 내부의 물이 분사노즐(3b)로 흘러가게 됨에 따라, 도 7에 도시한 바와 같이, 수압모터(10)의 임펠러(12)와 구동축(13)이 회전되어 상기 회동축(2a)을 도어패널(2)이 닫히는 방향으로 회동시켜 도어패널(2)이 닫히도록 한다.And, as the water inside the water supply pipe 3a flows to the injection nozzle 3b, as shown in FIG. 7, the impeller 12 and the drive shaft 13 of the hydraulic motor 10 are rotated to The door panel 2 is closed by rotating the coaxial shaft 2a in the direction in which the door panel 2 is closed.

이와 같이 구성된 수동방화유리문은 화재발생시 스프링클러(3)를 통해 공급되는 물의 수압을 이용하여 도어패널(2)을 자동으로 닫음으로, 화재발생시 도어패널(2)이 열려서 화재가 확산되는 것을 효과적으로 방지할 수 있는 장점이 있다.The passive fire glass door constructed as described above automatically closes the door panel 2 using the water pressure of the water supplied through the sprinkler 3 in the event of a fire, effectively preventing the spread of fire by opening the door panel 2 in the event of a fire.
