Description

선실 도어 방음장치{APPARATUS FOR NOISE CONTROL IN A DOOR OF A CABIN}Cabin Door Soundproofing {APPARATUS FOR NOISE CONTROL IN A DOOR OF A CABIN}

본 발명은 선실 도어 방음장치에 관한 것이다.The present invention relates to a cabin door soundproofing device.

잘 알려진 바와 같이, 우리나라는 끊임없는 기술개발과 원가경쟁력의 확보를 통해 세계 조선산업을 선도하고 있는 것으로 국제적으로 평가받고 있지만, 최근 중국은 국가차원의 지원과 저임금 노동력이 결합하여 조선산업이 급속히 발전하고 있는 상황이다.As is well known, Korea is internationally recognized as leading the global shipbuilding industry through constant technology development and cost competitiveness, but recently, China has rapidly developed shipbuilding industry by combining national support and low-wage labor force. It is a situation.

이러한 세계동향 안에서 우리나라의 조선산업이 향후에도 강자로 남기 위해서는 대형 여객선(이하 크루즈선)을 비롯한 초대형 컨테이너선, LNG선, FPSO(부유식 원유생산저장설비 선박, Floating Production Storage Offloading) 등 고부가가치 선박에 대한 기술개발이 적극적으로 추진되어야 함에 모두가 공감하고 있다.In order to remain strong in Korea's shipbuilding industry in the future, high value-added vessels such as large passenger ships (hereinafter referred to as cruise ships), ultra-large container ships, LNG carriers, FPSOs (floating oil production storage offshore vessels, and floating production storage offloading) Everyone agrees that technology development should be actively pursued.

예컨데, 크루즈선을 포함하는 여객선의 선실은 그 내부구조에 따라 데크별로 다양한 선실을 운영하고 있지만, 외기와 면하는 지의 여부에 따라, 외기와 면하고 있는 외측선실(Outside cabin)과 면하지 않는 내측선실(Inside cabin)로 나눌 때, 외측선실은 AO 및 BO의 두가지 형태가 있고, 내측선실은 AI 및 BI의 두가지 형태가 있으며, 통상 급수에 따라, 스위트(Suite) 선실, 발코니(Balcony) 선실(가장 룸이 많은 보편적 선실), 오션뷰(창문을 통해 바다 조망 가능), 인사이드(창문없는 내측선실)의 4가지 타입이 있고, 기타 발코니와 스위트 선실의 사이에 아쿠아클래스와 컨시어지 클래스를 포함하는 6가지 타입도 있으며, 동일급의 선실이라도 층의 위치, 선실의 위치 등 여러가지 조건에 따라 등급이 구분되며, 세부적인 카테고리로는 21가지 유형으로 구분된다.For example, the cabin of a passenger ship including a cruise ship operates various cabins for each deck according to its internal structure, but depending on whether or not it faces the outside, the cabin that faces the outside cabin does not face the outside cabin. When divided into an cabin, the outer cabin has two types, AO and BO, and the inner cabin has two types, AI and BI. Usually, depending on the water supply, the suite cabin and the balcony cabin ( There are four types: the most common cabins, the ocean view (viewing the sea through the window), the inside (the windowless inner cabin), and six other aqua and concierge classes between the balcony and suite cabins. There are also types, and even cabins of the same class are classified according to various conditions such as the location of the floor and the location of the cabin. The detailed categories are classified into 21 types.

한편, 선박을 구성하는 구조재의 경우, 운항 중의 화재 발생 시의 피해를 최소화하기 위하여 해상 인명 안전에 관한 국제 조약인 SOLAS(International convention for the Safety Of Life At Sea)에 근거하여 국제해사기관의 화재시험방법의 적용에 관한 국제 코드(FIP cord: Fire Test Procedures)에 따라 엄격하게 관리되고 있다.On the other hand, in the case of the structural members constituting the ship, in order to minimize the damage in the event of a fire during operation, the international maritime agency fire test based on the International Convention for Safety of Life at Sea (SOLAS) It is strictly controlled in accordance with the FIP cord: Fire Test Procedures.

하지만, 이러한 크루즈선 또는 여객선의 설계 및 운항기술에서 가장 중요한 부분 중의 하나가 승객에게는 승선 시의 쾌적성과 편의성을 제공하고, 승조원에게는 생산성 향상을 위한 쾌적한 근무환경을 제공하는 것이며, 이를 위해서, 선박 운항 시 엔진 가동으로 인해 선실에서 느낄 수 있는 소음을 일반 주택가에서 느끼는 소음 수준으로 낮추는 것이 매우 중요한 사항으로 대두되고 있다.However, one of the most important parts of the design and operation technology of such cruise ships or passenger ships is to provide passengers with comfort and convenience when boarding, and to provide crews with a pleasant working environment for improving productivity. It is very important to reduce the noise that can be felt in cabins due to the operation of municipal engines to the level of noise felt in residential districts.

통상, 선박 하부의 엔진실에 위치한 디젤엔진 등에 의해 선박 전체로 전파되는 소음으로 인하여, 엔진실에 가까운 격실의 경우 최대 93dB 정도의 높은 소음레벨을 나타내고, 선박 상부에 위치한 격실은 최소 42dB 정도의 낮은 소음레벨을 나타내며, 선박의 중간부위에 있는 승조원 거주구역의 격실은 대략 60-70dB 정도의 소음레벨을 나타내고 있으므로, 위치에 따라 적절한 방음조치가 필요하다.Normally, due to the noise propagated throughout the ship by diesel engines located in the engine compartment below the ship, the compartment close to the engine compartment shows a high noise level of up to 93 dB, and the compartment located above the ship has a low noise level of at least 42 dB. Since the compartments of crew accommodation spaces in the midship of ships represent noise levels of approximately 60-70 dB, appropriate sound insulation is required depending on the location.

또한, 최근에는 선주사들의 선실 소음에 대한 규정도 까다로워지고 있으며, 이러한 소음 문제가 선박의 시운전 기간이나 인도 후에 발생할 경우, 선실 구조 변경 등으로 많은 시간적, 금전적 손실이 발생하게 된다. 이에 선박의 설계단계에서 최적의 저소음 선실 설계를 구현하여 선사와의 마찰을 줄이고 사전에 손실을 방지할 필요가 있다.In addition, regulations on cabin noise of ship owners are becoming more difficult in recent years, and when such noise problem occurs after a trial run or delivery of a ship, a lot of time and money are lost due to a change in cabin structure. Therefore, it is necessary to implement the optimal low noise cabin design at the design stage of the ship to reduce friction with ships and prevent loss in advance.

한편, 한국공개특허 제10-2009-0034054호에는 소음시설설비를 이용한 저소음 선실 설계 방법을 개시하고 있으나, 이는 여객선의 저소음화에 적용가능한 최적의 선실 방음설계 및 제어 기술을 표준화할 수 있도록 할 뿐이다.On the other hand, Korean Patent Publication No. 10-2009-0034054 discloses a low noise cabin design method using a noise facility, but this only makes it possible to standardize the optimal cabin sound insulation design and control technology applicable to the low noise of passenger ships. .

한국등록실용신안 제20-0373428호에는 선실의 방화구조체를 개시하고 있으나, 이는 방화구조로 한정된 것으로 소음 저감과는 무관한 것이다.Korean Utility Model Registration No. 20-0373428 discloses a fire protection structure of a cabin, which is limited to a fire protection structure and is not related to noise reduction.

한국등록특허공보 제10-1045927호에는 선실 격벽용 코어를 개시하고 있으나, 이는 난연 성능의 향상에 관한 것인 바, 소음 저감과는 무관하다.

이하, 본 발명의 실시예를 첨부된 도면을 참조하여 상세히 설명하기로 한다. 아울러 본 발명을 설명함에 있어서, 관련된 공지 구성 또는 기능에 대한 구체적인 설명이 본 발명의 요지를 흐릴 수 있다고 판단되는 경우에는 그 상세한 설명을 생략한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

도 1은 복도와 접하는 선실 도어를 통해 선실로 유입되는 공기 흐름을 나타내며, 도 2는 도 1의 A-A선을 따라 취한 단면으로 선실 도어의 구성을 나타내고 있다.Figure 1 shows the air flow flowing into the cabin through the cabin door in contact with the corridor, Figure 2 is a cross-sectional view taken along the line A-A of Figure 1 shows the configuration of the cabin door.

도 1 및 도 2에 도시된 바와 같이, 선실(cabin)과 통로(corridor)사이에 위치되는 선실 도어(10)는 그 도어 본체(20)가 통로면(12)과 선실면(16)사이의 내부가 중공으로 형성되어 있다.As shown in FIGS. 1 and 2, the cabin door 10 located between the cabin and the corridor has a door body 20 between the passage face 12 and the cabin face 16. The inside is hollow.

공기는 도어 본체(20)의 통로면(12) 하부에 부착된 흡기구(14)를 통해 유입되어 선실면(16) 상부에 부착된 흡기구(18)를 통해 선실로 유입되며, 이에 따라 선박의 소음도 이러한 공기흐름을 통해 선실로 유입된다.Air is introduced through the inlet 14 attached to the lower portion of the passage surface 12 of the door body 20 and enters the cabin through the inlet 18 attached to the upper cabin surface 16. This airflow enters the cabin.

도어 본체(20)의 통로면(12)과 선실면(14)은 금속시트(steel sheet)(22)로 이루어질 수 있다.The passage face 12 and the cabin face 14 of the door body 20 may be made of a steel sheet 22.

각각의 금속시트(22)의 내측, 즉 도어 본체(20)의 내부 중공에는 차음부재(30)가 접합된다.The sound insulation member 30 is bonded to the inside of each metal sheet 22, that is, the inner hollow of the door body 20.

일반적인 선박 도어에서는 격벽의 코어로는 예로서, 석면, 글래스울, 세라믹울, 및 미네랄울(mineral wool)을 포함하는 유/무기물 코아와, 금속코아, 유기코아 등이 다양하게 활용되고 있다.In general ship doors, as cores of partition walls, for example, asbestos, glass wool, ceramic wool, mineral wool including mineral wool, metal core, organic core, and the like are variously used.

그러나, 석면은 발암 물질로 규정되어 사용이 금지되었으며, 글래스울, 세라믹울은 가격이 고가일 뿐만 아니라 분진 등으로 취급이 어려운 문제가 있다.However, asbestos has been prohibited as it is prescribed as a carcinogen, glass wool, ceramic wool is not only expensive but also difficult to handle with dust and the like.

또한 미네랄울은 가격 경쟁력, 불연성능 및 방음성능은 뛰어나나 비중이 높아 선박의 중량을 가중시키게 되며, 미세입자로 인한 피부염의 발생 가능성이 있어 바람직하지 못하다.In addition, mineral wool is excellent in price competitiveness, non-combustible performance and sound insulation performance, but the weight is high due to the high specific gravity, it is not preferable because there is the possibility of dermatitis due to fine particles.

그리고, 금속코아는 주로 알루미늄이 적용되어 방음성능은 우수하나 비용이 높아 FIP 코드 B급 테스트를 통과하지 못하는 문제점이 있다.In addition, the metal core is mainly applied to aluminum, the soundproofing performance is excellent but the cost is high, there is a problem that does not pass the FIP code class B test.

또한 유기코아의 경우, 가격이 낮고 비중이 낮은 장점은 있으나, 불연성 테스트를 통과하지 못하는 문제점이 있다.In addition, the organic core has a low price and low specific gravity, but there is a problem that does not pass the incombustibility test.

일반적인 선박 도어(10)는 이러한 이유로 차음부재(30)로서 미네랄울만을 사용하는 경우, 재료의 비산으로 인한 인체 유해성 면에서 문제가 있으므로, 본 발명의 선실 도어 방음장치에서는 차음부재(30)로서, 제 1 및 제 2 미네랄울층(32)과, 미네랄울층(32)의 사이에 방음구조체로서 접합된 코어층(40)을 포함한다.In general, when the ship door 10 uses only mineral wool as the sound insulation member 30 for this reason, there is a problem in terms of human hazards due to the scattering of the material, in the cabin door soundproofing device of the present invention as a sound insulation member 30, The core layer 40 bonded as a soundproof structure between the 1st and 2nd mineral wool layer 32 and the mineral wool layer 32 is included.

그리고, 본 발명의 제 1 실시예에 따른 선실 도어 방음장치로서, 도 3에 도시된 바와 같이, 코어층(40)은 PVC 워터팩으로 이루어질 수 있다.And, as a cabin door soundproofing device according to a first embodiment of the present invention, as shown in Figure 3, the core layer 40 may be made of a PVC water pack.

그 결과, 본 발명의 선실 도어 방음장치는 미네랄울의 사용량은 최소로 줄이면서도, 친환경 소재의 PVC 워터팩(PVC Water Pack)을 적용하여 차음성능을 극대화시킨 고성능 차음 도어(high noise reduction door)를 개발하게 되었다.As a result, the cabin door soundproofing device of the present invention is a high-performance soundproof door (high noise reduction door) to maximize the sound insulation performance by applying a PVC water pack of environmentally friendly materials while reducing the amount of mineral wool to a minimum Developed.

이와 달리, 본 발명의 제 2 실시예 및 제 3 실시예에 따른 선실 도어 방음장치로서, 도 4 및 도 5에 도시된 바와 같이, 알루미늄 폼(alumimun foam)으로 이루어진 코어층(40)을 채택할 수 있고, 코어층(40)을 PVC 워터팩과 알루미늄 폼을 결합하여 구성할 수 있으며, 상기 제 1 실시예와 마찬가지의 결과가 달성된다.Alternatively, as the cabin door soundproofing apparatus according to the second and third embodiments of the present invention, as shown in Figs. 4 and 5, the core layer 40 made of aluminum foam (alumimun foam) can be adopted. The core layer 40 can be constructed by combining a PVC water pack and an aluminum foam, and the same result as in the first embodiment can be achieved.

이와 같이 본 발명의 선실 도어 방음장치는 통로와 접하고 있는 선실 도어 중공 내부의 공기 흐름통로에 친환경 소재가 접합됨에 따라 선실로 유입되는 소음을 차단함으로써 차음 성능이 향상된다. As described above, the cabin door soundproofing device of the present invention improves sound insulation performance by blocking noise introduced into the cabin as the eco-friendly material is bonded to the air flow passage inside the cabin door hollow in contact with the passage.
