Here, the support plate 200 is preferably made of a flat plate of a square cross-section made of Invar, an alloy of steel and nickel.

상기 인바(invar)는 철에 니켈이 첨가된 열팽창계수가 작은 합금이며, 실온에서 온도가 변경되어도 치수 변화가 거의 없으므로, 화물창 내부의 온도 변화에 따른 지지판의 열팽창으로 인한 탑 브리지 패드(30) 및 탑 패드(31)의 손상을 방지할 수 있다.The invar is an alloy having a small coefficient of thermal expansion in which nickel is added to iron, and almost no dimensional change even when the temperature is changed at room temperature, so that the top bridge pad 30 due to the thermal expansion of the support plate according to the temperature change inside the cargo hold and Damage to the top pad 31 can be prevented.

구체적으로, 상기 지지판(200)은 길이가 상대적으로 길며, 폭과 높이가 얇은 빔 형상이며, 화물창 내부에서 작용되는 수직 하중에 대해 탑 브리지 패드를 지지하는 역할을 하게 된다. Specifically, the support plate 200 has a relatively long length, a beam shape having a thin width and height, and serves to support the top bridge pad against a vertical load acting inside the cargo hold.

상기 시공이 완료된 후 탑 패드가 고정되지 않는 인슐레이션 패널의 내측면에는 서플 트리플렉스가 에폭시 글루에 의해 부착되며, 균일한 접착품질을 위해 셋팅바를 이용하여 일정한 시간 동안 프레싱을 하게 된다.After the construction is completed, a triple triplex is attached to the inner surface of the insulation panel on which the top pad is not fixed by epoxy glue, and pressing is performed for a predetermined time using a setting bar for uniform adhesive quality.

상기 과정을 거친 후 상기 서플 트리플렉스가 부착된 인슐레이션 패널에는 탑 브리지 패드가 결합되고, 상기 결합과정에서 탑 브리지 패드 및 탑패드에 형성된 공간부에 지지판을 삽입하여 탑 브리지 패드를 탑 패드에 고정시키게 된다.After the above process, the top bridge pad is coupled to the insulation panel to which the supple triplex is attached, and the support plate is inserted into the space formed in the top bridge pad and the top pad to fix the top bridge pad to the top pad. do.

특히 상기 탑 브리지 패드를 삽입하는 과정은 별도의 체결구, 접착제 등이 요구되지 아니하므로 글루를 칠하거나 굳는 시간을 절약할 수 있어 시공 시간을 줄일 수 있게 된다.In particular, the process of inserting the top bridge pad does not require a separate fastener, adhesive, etc., thereby reducing the time required for painting or hardening, thereby reducing construction time.

마지막으로, 상기 탑패드와 탑 브리지 패드의 내측면에 코로게이트 멤브레인을 용접을 통해 결합시키게 된다.Finally, the corrogate membrane is bonded to the inner side surfaces of the top pad and the top bridge pad by welding.

이상과 같이 본 발명은 탑 브리지 패널의 시공이 간편한 구조를 채택한 액화천연가스 운반선의 화물창 방열구조를 제공하는 것을 기본적인 기술적인 사상으로 하고 있음을 알 수 있으며, 이와 같은 본 발명의 기본적인 사상의 범주 내에서, 당업계의 통상의 지식을 가진 자에게 있어서는 다른 많은 변형이 가능함은 물론이다.As described above, it can be seen that the present invention provides a basic technical idea to provide a cargo hold heat dissipation structure of a liquefied natural gas carrier that adopts a simple structure of a top bridge panel, and within the scope of the basic idea of the present invention. Of course, many other variations are possible to those of ordinary skill in the art.
