Description

철도차량의 차량간 연결막Intervehicle Membrane of Railroad Cars

본 고안은 철도차량의 차량과 차량사이에 설치되는 연결막에 관한 것으로, 특히 복수개의 천을 접합시켜 외부소음이 실내로 유입되는 것을 최대한 차단함과 동시에 내구강성과 유지보수성도 향상시킬 수 있도록 된 철도차량간 연결막 구조에 관한 것이다.The present invention relates to a connection membrane installed between a vehicle and a vehicle of a railway vehicle, and in particular, by joining a plurality of fabrics to prevent external noise from entering the room as much as possible, while also improving the oral resistance and maintainability. It relates to an inter-vehicle connection membrane structure.

철도차량의 차량사이에 설치되는 연결막(다이아프램:diaphragm)은 3차원방향으로 유동되는 차량과 차량사이에 설치되어 이를 통행하는 승객의 안전을 도모하고 차량운행시 외부소음과 각종 이물(異物)이 차실내로 유입되는 것을 차단시키도록 되어 있는 바, 이 같은 기능을 만족시키려면 승객을 충분하게 보호할 수 있도록 내구성이 있어야 하고, 외부소음을 차단할 수 있어야 하며 방수 및 방풍효과가 우수한 난연성 구조이어야 함은 물론, 착탈 및 정비보수가 용이하도록 플렉시블하면서 경량인 구조로 제작되어야 한다.The connecting membrane (diaphragm), which is installed between the vehicles of the railway vehicle, is installed between the vehicle and the vehicle that flows in the three-dimensional direction to promote the safety of passengers passing through the vehicle and to prevent external noise and various foreign objects during the operation of the vehicle. In order to satisfy this function, it is necessary to be durable enough to protect passengers, to be able to block external noise, and to be flame retardant structure with excellent waterproof and windproof effect. In addition, the ship should be made of a flexible and lightweight structure for easy removal and maintenance.

한편 이러한 연결막은 졸 타포린(Soal Tarpaulin)이라 불리우는 0.8㎜정도의 두께를 갖는 비닐천으로 구성한 휘장감으로 제작된 플렉시블형과 내부면에 스프링으로 지지되는 겹판이 취부된 링크형이 있다.On the other hand, such a connection membrane is a flexible type made of a drapery made of a vinyl cloth having a thickness of about 0.8 mm called sol tarpaulin (Soal Tarpaulin) and a link type mounted with a leaf plate supported on the inner surface.

그런데 상기와 같은 재질로 이루어진 종래의 연결막에 있어서, 플렉시블형 연결막은 유연성이 우수하여 정비 및 보수작업이 용이한 반면 소재가 비닐천으로 되어 있어 내구성이 취약하고, 방수와 방풍 및 소음차단효과도 떨어진다는 결점이 있다.By the way, in the conventional connection membrane made of the above material, the flexible connection membrane is excellent in flexibility and easy to maintain and repair, while the material is made of vinyl cloth, which is weak in durability, and waterproof, windproof and noise blocking effect is also achieved. There is a drawback to falling.

또한 링크형 연결막은 상기 플렉시블형 연결막보다는 상대적으로 견고하여 승객보호 효과가 우수하고 외관이 미려한 반면, 비교적 복잡한 구조로 설치되기 때문에 정비와 보수작업에 불편이 따르게 되고 연결막이 접혀질 때 겹판간의 간섭으로 자체마찰소음이 발생될 뿐 아니라, 밀폐가 되지 않아 플렉시블형 연결막과 마찬가지로 방수와 방풍 및 소음차단효과가 떨어진다는 결점이 있다.In addition, the link-type connection membrane is relatively harder than the flexible connection membrane, so that the passenger protection effect is excellent and the appearance is beautiful, whereas the link type connection membrane is installed in a relatively complicated structure, resulting in inconvenience in maintenance and repair work, and interference between the laminates when the connection membrane is folded. Not only does it generate self-friction noise, but also it is not sealed, so as with the flexible connection membrane, there is a disadvantage in that the waterproofing, windproof, and noise blocking effects are inferior.

이에 본 고안은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 기존에 사용되고 있는 졸 타폴린에 아라미드재질을 2중으로 설치하여 외피를 구성하고, 이 아라미드외측에 흡음재를 부착한 다음 그 위에 다시 인조가죽을 두르고 별도의 졸 타포린으로 마감처리를 함으로써, 외부로 부터 유입되는 소음을 최소화시키는 한편, 착탈성과 유지보수성을 향상시킬 수 있도록 된 철도차량의 차량간 연결막을 제공함에 그 목적이 있다.Therefore, the present invention was devised to solve the above problems, and a double layer of aramid material was used in the existing sol tarpaulin to form an outer shell, and the sound absorbing material was attached to the outside of the aramid, and then the artificial leather was placed thereon again. It is aimed to provide the inter-vehicle connecting membrane of the railroad car that can minimize the noise from the outside, and improve the detachability and maintainability by finishing with a separate sol tarpaulin.

상기와 같은 목적을 달성하기 위한 본 고안은, 4각형 지지프레임의 외주면에 둘러져 한쪽방향으로 루우프형상을 이루도록 연결막이 박음질로 고정되되, 이 연결막이 졸 타포린에 아라미드를 2중으로 설치한 구조로 외피를 구성하고, 상기 아라미드외측에 흡음재와 레자를 차례로 두르고 졸 타포린으로 마감처리된 구조로 이루어지는 한편, 하부면에 상기 지지프레임의 횡방향으로 슬라이드파스너를 부착하여 외부소음이 차실내로 유입되는 것을 효과적으로 방지할 수 있도록 되어 있다.In order to achieve the above object, the present invention is connected to the outer peripheral surface of the four-sided support frame to form a loop shape in one direction, and the fixing membrane is sewn in a fixed structure, and the connecting membrane has a structure in which aramid is installed in sol tarpaulin in double. And a sound absorbing material and leather on the outer side of the aramid in turn and finished with sol tarpaulin, while attaching a slide fastener in the transverse direction of the support frame to the lower surface to effectively prevent external noise from entering the vehicle interior. I can do it.

이하 본 고안을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 고안에 따른 연결막이 좁혀졌을 때의 측면도이고, 도 2는 본 고안에 따른 연결막이 펼쳐졌을 때의 측면도, 도 3은 도 1의 A-A선 단면도, 도 4는 도 3의 B-B선 단면도로써, 본 고안은 도면에 도시된 바와 같이 모서리부가 둥글게 형성된 4각형 지지프레임(1)의 외주면에 둘러져 한쪽방향으로 루우프형상을 이루도록 박음질된 연결막(2)이 복수의 고정부재(3)와 체결구(도시되지 않음)를 매개로 객실의 양 선단에 형성된 통로에 별도의 연결부재를 매개로 설치되어, 주름관형태를 유지하면서 상기 지지프레임(1)에 밀착고정된 상태에서 접혀지거나 펼쳐지도록 되어 있다.1 is a side view when the connection membrane according to the present invention is narrowed, FIG. 2 is a side view when the connection membrane according to the present invention is unfolded, FIG. 3 is a sectional view taken along line AA of FIG. 1, and FIG. 4 is a sectional view taken along line BB of FIG. As such, the present invention is connected to the plurality of fixing members 3 by a connecting film 2 sewn to form a loop shape in one direction by being surrounded by the outer circumferential surface of the quadrangular support frame 1 having a rounded corner portion as shown in the drawing. Through a sphere (not shown) is installed through a separate connecting member in the passage formed at both ends of the room, it is to be folded or unfolded in a state fixed close to the support frame 1 while maintaining the corrugated pipe shape. .

그리고 상기 연결막(2)은 내구성과 방수 및 방풍을 고려하여 외피를 기존에 사용되고 있는 졸 타포린에 아라미드(4:Aramid)를 2중으로 설치한 구조로 제조하는 한편, 외부소음이 유입되는 것을 저감시키기 위하여 상기 아라미드(4)외측에 흡음재(5)를 부착한 다음 그 위에 다시 인조가죽인 레자(6)를 두르고 별도의 졸 타포린(7)으로 마감처리된 구조로 되어 있다.In addition, the connecting membrane 2 is manufactured in a structure in which an aramid (4: Aramid) is installed in a double layer of sol tarpaulin, which is used in consideration of durability, waterproofing, and windproof, while reducing external noise. In order to attach the sound absorbing material (5) to the outside of the aramid (4), and then put the leather leather (6) again on it and has a structure finished with a separate sol tarpaulin (7).

또한 상기 연결막(2)의 하부에는 도 5에 도시된 바와 같이 지지프레임(1)에 대해 횡방향으로 소정길이로 슬라이드파스너(8)가 설치되어, 이 슬라이드파스너(8)를 잠궈주게 되면 빗물이나 오물 등을 외부로 배출시키기 위해 연결막(2) 하부에 형성된 배출구멍(도시되지 않음)을 통해 차실내로 유입되는 소음을 최대한 저감할 수 있게 된다.In addition, as shown in FIG. 5, the slide fastener 8 is installed at a predetermined length in the transverse direction with respect to the support frame 1, and when the slide fastener 8 is locked, rain water is provided in the lower portion of the connecting membrane 2. Through the discharge hole (not shown) formed in the lower portion of the connection film 2 to discharge the waste or the like to the outside it is possible to reduce the noise flowing into the vehicle as possible.

한편 상기 아라미드(4)는 방향족의 폴리아라미드(Polyaramid)섬유의 일종으로 강도와 탄성율, 인열강도 및 내절손력등에서 매우 우수한 특성을 갖고, 상기 흡음재(5)는 밀착성이 우수하고 용이하게 연결취부시킬 수 있는 한편, 상기 레자(6)는 차음성이 매우 우수하기 때문에, 연결막(2)을 통해 소음이 유입되는 것을 효과적으로 방지시킬 수 있고, 내구성과 방수 및 방풍면에 있어서도 우수한 효과를 나타내게 된다.On the other hand, the aramid (4) is a kind of aromatic polyaramid (Polyramid) fiber has very excellent properties in strength and elastic modulus, tear strength and fracture resistance, the sound absorbing material (5) has excellent adhesion and easy connection On the other hand, since the leather 6 has excellent sound insulation, it can effectively prevent noise from flowing through the connecting film 2, and exhibits excellent effects in terms of durability, waterproofing, and windproof surface. .

그리고 본 고안에 따른 연결막과 기존에 사용되고 있는 연결막의 소음차단효과를 비교해 본 결과, 기존의 연결막은 35.5㏈이고 본 고안에 따른 연결막은 46.3㏈로 측정되어, 본 고안에 따른 연결막이 약 10.8㏈정도의 소음차단효과가 있음을 알 수 있다.And as a result of comparing the noise blocking effect of the connecting membrane according to the present invention and the conventionally used connection membrane, the existing connecting membrane is measured 35.5㏈ and the connecting membrane according to the present invention is measured as 46.3㏈, the connection membrane according to the present invention is about 10.8㏈ It can be seen that there is a degree of noise blocking effect.

이상에서 설명한 바와 같이 본 고안 철도차량의 차량간 연결막에 따르면, 실내측에서 실외측 방향으로 아라미드와 흡음재, 인조가죽 및 졸 타포린을 4중으로 접합시켜 구성함으로써, 착탈성과 유지보수성을 유지하면서 외부로 부터 유입되는 소음을 최소화시키면서 할 수 있는 잇점이 있다.As described above, according to the inter-vehicle connecting membrane of the railway car, the aramid and the sound absorbing material, artificial leather, and sol tarpaulin are formed in four directions from the indoor side to the outdoor side, thereby maintaining detachability and maintainability. There is an advantage to minimize the incoming noise.
