본 고안은 층간소음방지용 구조를 갖는 더블 입상형 에어덕트에 관한 것으로, 그 기술적 요지는 아파트, 빌라, 다세대 주택 등에 시공되어 다가구의 실내공기를 외부로 배기 및 환기시키는 한편, 특히 공동주택에서 발생되는 층간소음이 이웃한 상,하층 주방 또는 화장실 등의 환기구를 통해 직통되지 않도록 복수의 에어덕트를 나란히 설치하되, 상기 에어덕트들에는 각 층별마다 결합되는 플렉시블덕트가 설정된 층 순번으로 번갈아가며 각각 다른 에어덕트와 연통됨으로써 상술한 층간소음이 일정한 구간내에서 절감될 수 있도록 형성되는 것을 특징으로 하는 층간소음방지용 구조를 갖는 더블 입상형 에어덕트에 관한 것이다.The present invention relates to a double granular air duct having a structure for preventing noise between floors. The technical idea is to be installed in apartments, villas, multi-family houses, etc. to exhaust and ventilate the indoor air of multi-family to the outside, and in particular, Install multiple air ducts side by side so that noise between floors does not go directly through the ventilation holes such as neighboring upper and lower kitchens or toilets, and the air ducts alternate with each other in turn by setting the flexible ducts to be combined for each floor. By communicating with the duct, the above-described interlayer noise relates to a double granular air duct having a structure for preventing interlayer noise, which is formed to be reduced within a predetermined section.

일반적으로 건식 에어덕트 시스템(DRY AIR DUCT SYSTEM)은 아파트 등의 공동주택에 시설되어 다가구의 주방, 욕실 등 실내에서 발생된 악취, 오염공기, 화재연기 등을 외부로 배기, 환기시키도록 형성된다.In general, a dry air duct system (DRY AIR DUCT SYSTEM) is installed in apartment houses, such as apartments are formed to exhaust and vent the odor, polluted air, fire smoke, etc. generated in the interior of a multi-family kitchen, bathroom, and the like.

이를 위해, 상기 공동(다층) 건축물에는 주방측과 욕실측의 일측면 선상에 설치(내설)되어 각 층마다 배기 시스템이 연결되도록 플렉시블덕트(3)가 부설된 건식 입상형 에어덕트가 형성된다.To this end, in the cavity (multi-storey) building, a dry granular air duct is installed on the one side line of the kitchen and bathroom side, and the flexible duct 3 is installed to connect the exhaust system to each floor.

이러한 종래의 건식 에어덕트 시스템은 도 2에 도시된 바와 같이, 건축물의 설정된 시공 통로에 수직방향으로 입상형 에어덕트(1:Air Duct)가 설치되고 특히, 상기 에어덕트의 일측 또는 타측 외주면상에는 별도의 새들(4)이 설치되어 각 층별 주방 또는 욕실 측의 플랙시블덕트(3)와 결합되도록 형성되며 상기 에어덕트(1)의 최상층(옥탑)에는 배기용타공판(5)이 설치되는 한편, 상기 배기용타공판(5)의 상부에는 배기팬(6)이 설치되어 집진된 오염공기를 대기로 배기시키도록 형성된다.In the conventional dry air duct system, as shown in FIG. 2, a vertical air duct (1: Air Duct) is installed in a vertical direction in a predetermined construction passage of a building, and in particular, on one side or the other outer circumferential surface of the air duct separately. Saddle (4) of the installation is formed to be coupled to the flexible duct (3) of the kitchen or bathroom side for each floor, and the exhaust air perforated plate (5) is installed on the top floor (rooftop) of the air duct (1), An exhaust fan 6 is installed on the exhaust perforated plate 5 to exhaust the collected polluted air into the atmosphere.

그러나 이와 같은 종래의 건식 에어덕트 시스템은 공동주택의 각 층을 연결하여 배기시스템을 형성함에 있어서, 중앙 에어덕트로부터 가지처럼 분기된 다수개의 플렉시블덕트(3)에 의해 이웃한 상,하층 발생 소음이 각 층별 주방 또는 화장실 환기구를 통해 직접 전달되는 바, 이는 별도의 층간 방음재 시설과는 무관하게 지속적으로 소음에 노출되는 문제가 발생되고 있다.However, such a conventional dry air duct system is connected to each floor of the apartment house to form an exhaust system, the noise generated by the neighboring upper and lower floors by a plurality of flexible ducts branched like branches from the central air duct Bars are directly transmitted through the kitchen or bathroom ventilation openings for each floor, which causes continuous noise exposure regardless of the separate floor soundproofing facility.

본 고안은 상기와 같은 종래의 문제점을 해결하기 위한 것으로, 그 기술적 요지는 아파트, 빌라, 다세대 주택 등에 시공되어 다가구의 실내공기를 외부로 배기 및 환기시키는 한편, 특히 공동주택에서 발생되는 층간소음이 이웃한 상,하층 주방 또는 화장실 등의 환기구를 통해 직통되지 않도록 복수의 에어덕트를 나란히 설치하되, 상기 에어덕트들에는 각 층별마다 결합되는 플렉시블덕트가 설정된 층 순번으로 번갈아가며 각각 다른 에어덕트와 연통됨으로써 상술한 층간소음이 일정한 구간내에서 절감될 수 있도록 형성되는 것을 특징으로 하는 층간소음방지용 구조를 갖는 더블 입상형 에어덕트를 제공함에 그 목적이 있다.The present invention is to solve the conventional problems as described above, the technical gist is installed in apartments, villas, multi-family houses, etc. to ventilate and ventilate the indoor air of the multi-family to the outside, in particular the floor noise generated in the apartment house A plurality of air ducts are installed side by side so as not to go directly through the ventilation openings of neighboring upper and lower kitchens or toilets, and the air ducts alternately communicate with other air ducts alternately with the flexible ducts set in each floor. It is an object of the present invention to provide a double granular air duct having a structure for preventing the noise between layers, which is formed so that the above-described noise between layers can be reduced within a predetermined section.

상술한 목적을 달성하기 위한 본 고안은 복층 이상의 다층 구조를 갖는 공동 주택에 시공되어 실내공기의 배기, 환기를 유도하도록 형성되는 입상형 에어덕트에 있어서, 각 층간에서 발생된 소음이 주방 또는 욕실의 환기구를 통해 이웃한 상층 및 하층으로 직통되지 않도록 홀수층 또는 짝수층 중 설정된 어느 층에만 부설되는 제1플렉시블덕트(100)와; 상기 제1플렉시블덕트(100)가 부설된 홀수층 또는 짝수층을 피해 그 사이 층간마다 부설되는 제2플렉시블덕트(200)와; 상기 제1플렉시블덕트(100)와 수직 연결되도록 형성되는 제1에어덕트(300)와; 상기 제2플렉시블덕트(200)와 수직 연결되도록 형성되는 제2에어덕트(400)가; 구성되어 이루어진다.The present invention for achieving the above object is a granular air duct that is formed in a multi-storey multi-storey multi-unit housing to induce the exhaust, ventilation of the indoor air, the noise generated between each floor of the kitchen or bathroom A first flexible duct 100 installed only on an odd layer or an even layer so as not to be directly connected to the adjacent upper and lower layers through a ventilation hole; A second flexible duct 200 which is installed every layer between the odd and even layers on which the first flexible duct 100 is installed; A first air duct (300) formed to be vertically connected to the first flexible duct (100); A second air duct 400 formed to be vertically connected to the second flexible duct 200; It is made up.

다음은 첨부된 도면을 참조하며 본 고안을 자세히 설명하겠다.Next, the present invention will be described in detail with reference to the accompanying drawings.

먼저 도 1에 도시된 바와 같이, 본 고안은 상시 오픈되어 연결된 주방 또는 화장실의 환기용 제1,2플렉시블덕트(100,200)를 설정된 층 순번으로 번갈아가며 복수의 제1,2에어덕트(300,400) 중 각각 다른 에어덕트와 연통되도록 형성됨으로써 층간소음이 이웃한 상,하층 가구에게 직통되지 않도록 구성된다.First, as shown in FIG. 1, the present invention alternates the first and second flexible ducts 100 and 200 for ventilation of a kitchen or a bathroom connected to the floor in order of a set floor order among a plurality of first and second air ducts 300 and 400. It is formed so as to communicate with each other air duct, so that the noise between floors is not directly connected to the neighboring upper and lower furniture.

이에 상기 제1플렉시블덕트(100)는 각 층간에서 발생된 소음이 주방 또는 욕실의 환기구를 통해 이웃한 상층 및 하층 가구로 직통되지 않도록 홀수층 또는 짝수층 중 설정된 어느 층에만 부설된다.Accordingly, the first flexible duct 100 is installed only on an odd floor or an even floor set so that noise generated between floors does not go directly to neighboring upper floors and lower floor furniture through ventilation holes in the kitchen or bathroom.

이때, 상기 제1플렉시블덕트(100)는 제1에어덕트(300)와 별도의 분배관을 통해 수직 연결된다.In this case, the first flexible duct 100 is vertically connected to the first air duct 300 through a separate distribution pipe.

이러한 제1플렉시블덕트(100)는 일 실시예로써, 제1에어덕트(300)와 연결되되 해당 홀수층에서만 상기 제1에어덕트(300)와 결합되도록 형성됨으로써 최소한 짝수층에 대한 간격(높이)만큼 소음절감 구간이 형성되어 이웃한 층간소음으로부터 일정한 방음효과가 발생된다.In an embodiment, the first flexible duct 100 is connected to the first air duct 300, but is formed to be coupled to the first air duct 300 only in an odd numbered layer, thereby providing a spacing (height) of at least the even layer. As the noise reduction section is formed, a constant sound insulation effect is generated from neighboring floor noise.

즉, 상시 오픈 상태로 개구된 주방 또는 욕실측의 환기구를 통해 발생된 소음이 제1에어덕트(300)로 하여금 짝수층 구간을 지나면서 소멸되도록 유도하여 결국 소음이 절감된다.That is, the noise generated through the ventilation opening of the kitchen or bathroom side open in the normally open state induces the first air duct 300 to pass through the even-numbered section to reduce noise.

한편, 상기 제2플렉시블덕트(200)는 일 실시예로써, 제1플렉시블덕트(100)가 부설된 홀수층을 피해 그 사이 층간인 짝수층마다 부설되도록 형성된다.On the other hand, the second flexible duct 200 is formed to be installed in every even layer between the layers to avoid the odd layer in which the first flexible duct 100 is installed.

이때, 상기 제2에어덕트(400)는 별도의 분배관을 통해 제2플렉시블덕트(200)와 수직 연결되도록 형성된다.In this case, the second air duct 400 is formed to be vertically connected to the second flexible duct 200 through a separate distribution pipe.

이러한 제2플렉시블덕트(200)는 제1플렉시블덕트(100)와는 달리 제2에어덕트(400)에만 결합됨으로써, 홀수층에 대한 간격(높이)만큼 소음절감 구간이 형성되어 이웃한 층간소음으로부터 일정한 방음을 실현하게 된다.Unlike the first flexible duct 100, the second flexible duct 200 is coupled to only the second air duct 400, so that a noise reduction section is formed by an interval (height) with respect to the odd layer, and thus is constant from neighboring floor noise. Sound insulation is realized.

즉, 상시 오픈 상태로 개구된 주방 또는 욕실측의 환기구를 통해 발생된 소음이 제2에어덕트(400)로 하여금 홀수층 구간을 지나면서 소멸되도록 유도하여 결국 소음이 절감된다.That is, the noise generated through the ventilation opening of the kitchen or bathroom side open in the normally open state induces the second air duct 400 to disappear as it passes through the odd-numbered section, thereby reducing noise.

이상과 같이, 본 고안은 아파트, 빌라, 다세대 주택 등에 시공되어 다가구의 실내공기를 외부로 배기 및 환기시키는 한편, 특히 공동주택에서 발생되는 층간소 음이 이웃한 상,하층 주방 또는 화장실 등의 환기구를 통해 직통되지 않도록 복수의 에어덕트를 나란히 설치하되, 상기 에어덕트들에는 각 층별마다 결합되는 플렉시블덕트가 설정된 층 순번으로 번갈아가며 각각 다른 에어덕트와 연통됨으로써 상술한 층간소음이 일정한 구간내에서 절감되는 효과가 있다.As described above, the present invention is constructed in apartments, villas, multi-family houses, etc. to exhaust and ventilate the indoor air of multi-family to the outside, and in particular, ventilation openings such as upper and lower kitchens or toilets with adjacent floor noise generated in apartments. A plurality of air ducts are installed side by side so as not to be directly communicated through the air ducts, and the flexible ducts coupled to each floor alternately communicate with the other air ducts alternately in the set floor order, thereby reducing the above-mentioned floor noise within a certain section. It is effective.
