Description

비연속 내화충전재 일체형 방화덕트 시스템 {Non-continuous fireproof filler integrated fire duct system}Non-continuous fireproof filler integrated fire duct system

본 고안은 비연속 내화충전재 일체형 방화덕트 시스템에 관한 것으로서, 보다 상세하게는 화재로 인한 화염이나 유독가스가 덕트를 통해 인접하는 구획공간으로 확산되는 것을 효과적으로 차단시킬 수 있는 비연속 내화충전재 일체형 방화덕트 시스템에 관한 것이다.The present invention relates to a non-continuous fire-resistance filler-integrated fire duct system, and more particularly, a non-continuous fire-resistance filler-integrated fire duct that can effectively block the spread of flames or toxic gases from fire to adjacent compartments through the duct. It's about the system.

인구가 밀집되어 있는 아파트 등의 공동주택은 물론 하나의 건물 내에 다양한 시설물들이 복합적으로 사용되고 있으며, 이러한 대규모 건물은 소방안전을 위해 다양한 형태의 방재, 방화 설비를 구축하도록 법적으로 규제하고 있지만, 화재 발생시 이를 효과적으로 방지하거나 억제하기에는 부족한 것이 현실이다.A variety of facilities are used in a single building as well as multi-unit housing such as apartments with a dense population, and these large-scale buildings are legally regulated to build various types of disaster prevention and fire protection facilities for fire safety. The reality is that it is insufficient to effectively prevent or suppress it.

건물에 화재가 발생할 경우, 화염에 의한 피해보다 화염에 의해 유발된 유해가스가 포함된 연기에 질식하여 발생되는 인명 피해가 더 크기 때문에, 유독한 연소가스의 유동을 최대한 차단하기 위한 제연 설비나 환기시스템은 건물의 대형화와 함께 매우 중요한 방재요소로 볼 수 있다.In the event of a fire in a building, a smoke control system or ventilation system to block the flow of toxic combustion gas as much as possible because the damage to human life caused by suffocation by smoke containing harmful gas caused by a flame is greater than the damage caused by the flame. The system can be seen as a very important disaster prevention factor along with the enlargement of the building.

방화구획은 건축물 화재시 화염 및 연기의 확산 방지를 위한 방호공간으로서 중요한 역할을 행하게 되며, 스프링클러 등의 초기 화재진압설비에 의한 소화에 실패한 경우, 화재는 인접된 공간으로 수평 및 수직으로 확산하게 된다.The fire compartment plays an important role as a protective space to prevent the spread of flame and smoke in case of a fire in a building. .

이 때, 방화구획을 구성하는 구조체와 설비적 요소들이 제 기능을 행하지 못하면 대형 화재로 발전하게 되며, 이러한 방화구획 개구부 및 관통부분이 연기와 화염을 인접공간으로 확대시키는 주요 통로가 될 수 있다.At this time, if the structures and equipment elements constituting the fire compartment do not function properly, a large fire will develop, and the opening and penetration portion of the fire compartment may be the main passage for expanding the smoke and flame to the adjacent space.

현행 건축 관련 법규에는, 건축물의 용도에 따라 일정한 내화구조의 성능기준에 대해 명시되어 있으며, 화염이나 열의 전파를 제어할 수 있는 내화성능을 확보함으로써 소정 시간 동안 구획 밖으로 화재가 확산되는 것을 방지하여야 한다.The current building-related laws and regulations specify the performance standards of certain fire-resistance structures according to the purpose of the building. .

일반 건축물에서 화재가 발생할 경우, 실내에서 발생된 화염이 덕트를 통해 인근 구역으로 옮겨 붙는 현상이 발생하게 되므로, 방화구획의 수평, 수직 설비 관통부, 조인트 및 커튼월과 바닥 사이 등의 틈새를 밀폐함으로써 연기나 화염이 급속히 확산되는 것을 방지하기 위한 다양한 방안들이 강구되고 있다.In the event of a fire in a general building, a phenomenon occurs where the flame generated from the room is transferred to the adjacent area through the duct. By doing so, various measures are being taken to prevent the rapid spread of smoke or flames.

본 고안은 상기와 같은 종래 문제점을 해결하기 위한 것으로서, 본 고안의 목적은 방화 성능을 대폭 향상시켜 화재 발생시 덕트 내에서의 내화 소재가 발포 및 팽창하여 틈새를 밀폐시킴으로써 인접 구획공간으로 화염의 전파나 열 전달을 차단하여 화재 확산을 근본적으로 방지할 수 있는 비연속 내화충전재 일체형 방화덕트 시스템을 제공하는데 있다.The present invention is to solve the problems of the prior art as described above, and the purpose of the present invention is to significantly improve the fire protection performance, so that when a fire occurs, the fireproof material in the duct foams and expands to seal the gap, thereby preventing the propagation of flames to adjacent compartments or An object of the present invention is to provide a non-continuous fire-resistance filler-integrated fire duct system that can fundamentally prevent the spread of fire by blocking heat transfer.

이러한 목적을 달성하기 위한 본 고안은, 건물 내의 화재로 인한 화염이나 유독가스가 덕트를 통해 인접하는 구획공간으로 확산되는 것을 차단시키기 위한 구조로서, 구획공간을 이루는 양측 방화벽체를 사이에 두고 연이어 설치되는 덕트와, 상기 방화벽체의 관통부 내에 설치되어 덕트를 상호 연결하기 위한 하우징과, 이 하우징의 내부에 개폐 가능하도록 장착되는 댐퍼와, 상기 하우징의 외측에 배치되어 방화벽체의 측벽에 밀착되도록 설치되는 내화보드와, 이 내화보드와 간격을 두고 덕트의 측벽에 설치되는 발포 내화가스켓과, 상기 하우징 내부의 댐퍼를 사이에 두고 내면에 장착되는 내화충전재를 포함하여 구성된다.The present invention for achieving this purpose is a structure to block the spread of flames or toxic gases caused by a fire in a building to an adjacent compartment through a duct, and is installed consecutively with both firewalls forming the compartment in between a duct, a housing installed in the penetration portion of the firewall to interconnect the ducts, a damper mounted to be opened and closed inside the housing, and a damper disposed outside the housing and installed so as to be in close contact with the sidewall of the firewall a fire resistant board, a fire resistant gasket installed on the side wall of the duct at a distance from the fire resistant board, and a fire resistant filler mounted on the inner surface of the housing with a damper therebetween.

또한, 상기 내화보드는 PVC 수지와 팽창흑연 및 무기발포재, 실리카계 무기물을 혼합하여 압출 성형에 의해 제조된 충전재에 강판을 부착하여 구성한 것이며, 상기 내화보드의 외측에는 발포 내화가스켓을 수용하는 차열재가 비연속적으로 감겨져 설치된다.In addition, the fire resistant board is constructed by attaching a steel plate to a filler manufactured by extrusion molding by mixing PVC resin, expanded graphite, inorganic foaming material, and silica-based inorganic material, and a car accommodating a foamed fire gasket on the outside of the fire resistant board Heating material is discontinuously wound and installed.

본 고안은 상기한 바와 같은 특징들에 의해, 방화벽체의 관통부에 장착되는 하우징 상에 방화 성능이 우수한 내화보드나 발포 내화가스켓, 내화충전재 등을 설치함에 따라 구획공간에서의 화염이나 열이 전달되는 것을 근본적으로 차단할 수 있게 되며, 덕트의 외측에 설치되는 차열재를 비연속 시공으로 함으로써 종전에 비해 화재 안전성 및 시공성이 우수하여 공기를 단축하고 시공비를 절감할 수 있는 것이다.According to the above-described characteristics, the present invention transmits flame or heat in a compartment by installing a fireproof board, foamed fire gasket, fire resistant filler, etc. with excellent fire protection performance on the housing mounted on the penetration part of the firewall body. It is possible to fundamentally block the fire, and by discontinuous construction of the insulating material installed on the outside of the duct, it is possible to shorten the construction period and reduce the construction cost due to superior fire safety and constructability compared to the past.

이하, 첨부 도면을 참조하여 본 고안에 따른 바람직한 실시예를 보다 상세하게 설명하지만, 이들이 갖는 특정 구조 및 기능은 하나의 구성예를 나타낸 것이므로 본 명세서에 기재된 실시예에만 한정되는 것은 아니다.Hereinafter, preferred embodiments according to the present invention will be described in more detail with reference to the accompanying drawings, but the specific structures and functions they have are not limited to the embodiments described in this specification because they represent one configuration example.

우선, 본 고안이 적용되는 바람직한 예로서 등록특허 제1283204호에 개시되어 있는 일부 종래기술에 대하여 설명하고, 또한 이에 따른 문제점을 도출한 후에 본 고안의 구성 및 작용효과에 대하여 후술하고자 한다.First, some prior art disclosed in Patent Registration No. 1283204 will be described as a preferred example to which the present invention is applied, and the configuration and effects of the present invention will be described later after deriving the related problems.

첨부된 도 1 및 도 2에 도시된 바와 같이, 방화용 댐퍼(1)는 덕트(10)의 중간에 일체로 고정되는 프레임(20)을 구비하며, 이 프레임(20)의 내측에 다수의 블레이드(30)들이 나란하게 회전 가능하도록 장착되어 있다.1 and 2, the fire damper 1 has a frame 20 integrally fixed in the middle of the duct 10, and a plurality of blades on the inside of the frame 20 (30) are mounted side by side rotatable.

이 블레이드(30)들은 프레임(20)의 내측 중앙에 배치된 연결링크(40)들이 블레이드(30)의 중간을 상하방향으로 연결하며, 최상부측 블레이드(40)에는 블레이드 고정용 퓨즈(50)가 프레임(20)과의 사이를 연결하고, 최하부측 블레이드(30)에는 스프링(60)이 프레임(20)과 사이를 연결하도록 구성된다.The blades 30 have connecting links 40 disposed in the inner center of the frame 20 to connect the middle of the blade 30 in the vertical direction, and the uppermost blade 40 has a fuse 50 for fixing the blade. It connects between the frame 20 and the lowermost blade 30, a spring 60 is configured to connect between the frame 20 and the frame 20.

이러한 방화용 댐퍼(1)는 프레임(20)의 내측 블레이드(30)들이 개방된 상태를 유지하게 된다.The fire damper 1 maintains the inner blade 30 of the frame 20 in an open state.

건물에 화재가 발생하는 경우, 덕트(10)의 내부를 통과하는 화염과 유독 가스에 의해 블레이드 고정용 퓨즈(50)가 용융됨과 동시에 스프링(60)의 탄성 복원력이 작용하여 블레이드(30)들을 일시에 닫음에 따라 덕트(10)를 통한 화염과 유동가스가 인접하는 방화구획으로 전파하는 것을 차단시키게 된다.When a fire occurs in a building, the fuse 50 for fixing the blade is melted by the flame and toxic gas passing through the inside of the duct 10 and, at the same time, the elastic restoring force of the spring 60 acts to temporarily hold the blades 30. As it closes, it blocks the propagation of the flame and the flowing gas through the duct 10 to the adjacent fire compartment.

상기 방화용 댐퍼(1)에서 블레이드 고정용 퓨즈(50)의 동작온도는 통상적으로 72℃의 온도에서 용융되도록 제작되어 최상부측 블레이드(30)에 설치된다. 이에 따라 화재 등의 비상상황이 아닌 경우에도 블레이드 고정용 퓨즈(50)가 용융되어 탈락함으로써 블레이드(30)들이 오동작을 일으키게 된다.The operating temperature of the fuse 50 for fixing the blade in the fire damper 1 is typically manufactured to melt at a temperature of 72° C. and installed on the uppermost blade 30 . Accordingly, even in non-emergency situations such as fire, the fuse 50 for fixing the blade is melted and dropped, thereby causing the blades 30 to malfunction.

또, 상기 블레이드 고정용 퓨즈(50)는 사용 기간이 오래됨에 따라 자연적인 부식에 의해 탈락강도가 떨어져 용융되지 않은 상태에서도 외력에 의해 블레이드(30)들이 닫히는 경우도 있다.In addition, as the period of use of the fuse 50 for fixing the blades increases, the strength of the blades 30 may be closed by an external force even in an unmelted state due to a drop in strength due to natural corrosion.

따라서, 건물 내의 환기 작동이 이루어지지 않게 되므로 상당한 비용을 들여 교체해야만 한다. 뿐만 아니라 프레임(20) 내의 블레이드(30)들이 설치된 연결링크(40)는 물론 블레이드(30)를 프레임(20)에 연결시키기 위한 샤프트(32)의 경우 일정기간 사용시 부식을 초래하여 구조적인 강도를 저하시킴으로써, 화재가 발생하지 않은 상황에서도 블레이드(30)를 오동작시키는 경우가 발생하게 된다.Therefore, the ventilation operation in the building is not performed, and it must be replaced at a considerable cost. In addition, in the case of the shaft 32 for connecting the blade 30 to the frame 20, as well as the connecting link 40 in which the blades 30 in the frame 20 are installed, corrosion occurs during use for a certain period of time to increase structural strength. By lowering, the blade 30 may malfunction even in a situation in which a fire does not occur.

본 고안은 상술한 바와 같은 종래기술에 있어서의 문제들을 고려하여 제안하고자 하는 바이며, 이에 대하여 첨부된 도 3 내지 도 5를 참조로 설명한다.The present invention is intended to be proposed in consideration of the problems in the prior art as described above, and will be described with reference to FIGS. 3 to 5 attached thereto.

이들 도면에 도시된 바와 같이, 본 고안은 건물 내의 양측 방화벽체(70)를 사이에 두고 덕트(75)가 연이어 설치되고, 상기 방화벽체(70)에 형성된 관통부 내에는 덕트(75)를 연결하기 위한 하우징(80)이 일체형으로 조립된다.As shown in these drawings, in the present invention, the ducts 75 are sequentially installed with both sides of the firewall body 70 interposed therebetween, and the ducts 75 are connected in the penetration portion formed in the firewall body 70 . The housing 80 for this purpose is integrally assembled.

이 하우징(80)의 내부에는 통로를 개폐하기 위한 댐퍼(81)가 설치되어 있다. 이 댐퍼(81)는 힌지(82a)를 중심으로 회동하는 날개판(82b)으로 이루어짐과 동시에 이 날개판(82b)에 휴즈(83) 및 탄성스프링(84)이 각각 연결 설치됨에 따라 평상시에는 덕트(75) 내부로 실내 공기가 유통되는 한편, 화재시 덕트(75)를 타고 역류하는 화염의 유입을 차단하도록 구성된다.A damper 81 for opening and closing the passage is provided inside the housing 80 . The damper 81 is composed of a wing plate 82b rotating around a hinge 82a, and at the same time, a fuse 83 and an elastic spring 84 are connected to the wing plate 82b. (75) While the indoor air is circulated to the inside, it is configured to block the inflow of the flame flowing backward through the duct 75 in the event of a fire.

즉, 화염에 의해 휴즈(83)가 단락되면서 힌지(82a)를 기준으로 날개판(82b)이 하우징(80)에 결속된 탄성스프링(84)의 작용에 의해 날개판(82b)을 끌어당김으로써 하우징(80)의 내부를 차폐할 수 있게 된다.That is, as the fuse 83 is short-circuited by the flame, the wing plate 82b is pulled by the action of the elastic spring 84 bound to the housing 80 with respect to the hinge 82a by pulling the wing plate 82b. It is possible to shield the inside of the housing 80 .

이러한 댐퍼(75)의 구성이나 작용은 통상적으로 적용되고 있는 것이므로 이에 대한 상세 설명은 생략한다.Since the configuration or action of the damper 75 is generally applied, a detailed description thereof will be omitted.

한편, 상기 방화벽체(70)의 관통부 외측에는 내화보드(85)가 밀착되도록 설치됨과 동시에 하우징(80)의 외측에 배치되고, 이 내화보드(85)와 간격을 두고 하우징(80)의 측벽에는 발포 내화가스켓(90)이 설치되어 있으며, 상기 하우징(80) 내부의 댐퍼(81)를 사이에 두고 내화충전재(95)가 장착되어 있다.On the other hand, the fire resistant board 85 is installed to the outside of the penetration part of the firewall body 70 and disposed outside the housing 80 at the same time, and the side wall of the housing 80 is spaced apart from the fire resistant board 85 . A foamed fire resistant gasket 90 is installed, and a fire resistant filler 95 is mounted with a damper 81 inside the housing 80 interposed therebetween.

상기 내화보드(85)는 PVC 수지와 팽창흑연 및 무기발포재, 실리카계 무기물을 혼합한 후 압출 성형에 의해 제조한 제품을 적용할 수 있다. 평상시 외관은 고무판 형태를 이루게 되지만 화재로 인한 온도 상승시 거의 40∼50배 이상으로 발포·팽창됨에 따라 주변 틈새를 차단하여 화재의 확산이나 열 전달을 억제할 수 있는 특성을 갖추고 있다.The fire resistant board 85 may be a product manufactured by extrusion molding after mixing PVC resin, expanded graphite, inorganic foaming material, and silica-based inorganic material. Normally, the exterior takes the form of a rubber plate, but when the temperature rises due to fire, it foams and expands by almost 40 to 50 times.

즉, 4∼10㎜ 두께의 충전재에 강도 보강을 위한 0.5mm 강판을 부착하여 구성되며, 기존 공법은 바닥 또는 벽체와 덕트 틈새의 좁은 공간에 삽입하는 시공상의 어려움을 개선하여 내화보드(85)를 덕트 측면에 붙인 후 바닥/벽 표면에 고정시켜 마감 처리함에 따라 종전에 비해 설치가 용이하여 시공성을 크게 개선할 수 있다.That is, it is composed by attaching a 0.5 mm steel plate for strength reinforcement to a filler having a thickness of 4 to 10 mm, and the existing construction method improves the difficulty of inserting into a narrow space between the floor or wall and the duct gap, thereby making the fire resistant board 85. After attaching it to the side of the duct, it is fixed to the floor/wall surface and finished.

또, 화재로 인한 900∼1,000℃에 이르는 고열 발생시 발포·팽창하면서 주변 틈새를 차단하여 화염의 전파 및 열 전달을 차단함으로써 화재가 확산되는 것을 효과적으로 억제할 수 있다.In addition, it is possible to effectively suppress the spread of fire by blocking the fire propagation and heat transfer by blocking the surrounding gap while foaming and expanding when high heat of 900~1,000℃ is generated due to a fire.

상기 발포 내화가스켓(90) 및 내화충전재(95)의 경우에도 전술한 내화보드()의 충전재와 동일한 특성을 지니고 있는 제품으로 화장의 확산이나 열 전달을 억제할 수 있다.Even in the case of the foamed fireproof gasket 90 and the fireproof filler 95, the product having the same characteristics as the filler of the fireproof board () can suppress the diffusion of makeup or heat transfer.

또한, 상기 내화보드(85)의 외측에는 발포 내화가스켓(90)을 수용하는 차열재(91)가 비연속적으로 감겨져 설치된다. 이 차열재(91)는 방화벽체(70)에 인접하여 설치된 덕트(75)의 외주 둘레에 감겨지도록 소프트한 소재의 불연재 또는 난연재를 이용할 수 있으며, 예컨대 1,000℃ 이상의 고열에 견디는 세라믹 울(Ceramic wool)로 제작하는 것이 바람직하다.In addition, the heat shield 91 for accommodating the foamed fire resistant gasket 90 is discontinuously wound and installed on the outside of the fire resistant board 85 . The heat shield 91 may use a soft non-combustible or flame-retardant material so as to be wound around the outer periphery of the duct 75 installed adjacent to the firewall body 70, for example, ceramic wool that withstands high heat of 1,000° C. or more. ) is preferred.

또, 통상의 연질 소재의 매트 및 이 매트의 외측을 전체적으로 감싸면서 필름 형태로 이루어진 커버로 구성하는 것도 가능하다. 이로 인해 화재가 발생하더라도 다른 구역으로 열이 전달되어 주변의 인화물질이 발화되는 것을 방지할 수 있다.In addition, it is also possible to configure a mat made of a conventional soft material and a cover made of a film while enclosing the outside of the mat as a whole. Even in the event of a fire, heat can be transferred to other areas to prevent ignition of nearby flammable materials.

전술한 바와 같이, 본 고안에 있어서의 비연속 내화충전재 일체형 방화덕트 시스템에 의하면, 방화벽체의 관통부에 장착되는 하우징 상에 방화 성능이 우수한 내화보드나 발포 내화가스켓, 내화충전재 등을 설치함에 따라 구획공간에서의 화염이나 열이 전달되는 것을 근본적으로 차단할 수 있게 되며, 덕트의 외측에 설치되는 차열재를 비연속 시공으로 함으로써 종전에 비해 화재 안전성 및 시공성이 우수하여 공기를 단축하고 시공비를 절감할 수 있는 것이다.As described above, according to the non-continuous fire-resistance filler-integrated fire duct system of the present invention, as a fire-resistance board, foam fire-resistance gasket, fire-resistance filler, etc. having excellent fire protection performance are installed on the housing mounted on the penetration part of the firewall body, It is possible to fundamentally block the transmission of flame or heat from the compartment space, and by discontinuous construction of the heat shield installed on the outside of the duct, it has excellent fire safety and workability compared to the past, which shortens the construction period and reduces the construction cost. it can be

이상에서와 같은 기술적 구성에 의해 본 고안의 기술적 과제가 달성되는 것이며, 비록 한정된 실시예와 도면에 의해 설명되었으나 여기에 한정되지 않고 본 고안이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 본 고안의 기술사상과 아래에 기재될 청구범위의 균등범위 내에서 다양한 수정 및 변형이 가능한 것임은 물론이다.The technical task of the present invention is achieved by the technical configuration as described above, and although described by the limited embodiments and drawings, the present invention is not limited thereto by those of ordinary skill in the art to which the present invention belongs.
