Abstract: 본 발명은 저온 또는 고온의 액체용 탱크, 예를 들어, 액화천연가스 운반선의 화물창의 단열방벽 접합구조에 관한 것이다. 더욱 상세하게는 접합부재의 파괴 인성을 향상시킬 수 있는 단열방벽 접합구조에 관한 것이다. 본 발명에 따른 단열방벽 접합구조는 일정한 간격으로 배열되어 있는 복수의 단열패널들의 표면에 접합된 면재와, 복수의 상기 단열패널들 사이의 틈새를 덮도록, 인접하는 두 개의 상기 단열패널들의 표면에 접합된 면재 위에 배치되는 스트립과, 상기 면재와 스트립 사이에 배치되어 상기 면재와 스트립을 결합하는 접합부재를 포함하며, 상기 접합부재는 폴리머 접착제와 폴리머 접착제에 분산된 단섬유를 포함한다. 본 발명에 따른 단열방벽 접합부재는 고강도의 단섬유에 의해서 보강되므로, 균열진전이 억제되고 파괴인성이 향상된다.
Abstract translation: 本发明涉及一种用于在低温或高温下液体的罐的绝缘阻挡接合结构，例如LNG运输工具中的货舱，更具体地说，涉及一种能够改善接头的断裂韧性的绝缘阻隔接头结构 会员。 绝缘阻挡接头结构包括：接合在多个绝缘面板的表面上并以规则间隔排列的面杆; 放置在接合在两个相邻绝缘板的表面上的面棒上的条，以便覆盖多个绝缘板之间的间隙; 以及联接构件，其被放置在面棒和条带之间以便粘合面杆和条。 接头构件包括聚合物粘合剂和分散在聚合物粘合剂中的长丝。 因此，通过高强度的细丝来增强隔热接合构件，能够限制裂纹扩展，提高断裂韧性。

Abstract: Disclosed is a vibration isolation structure of a cargo hold for a liquefied natural gas (LNG) carrier capable of absorbing impact to damp vibration. The present invention comprises: a first barrier having one surface with which LNG is in contact, and multiple membranes on which multiple wrinkles are concavely formed to absorb the contraction and the expansion caused by thermal deformation; a first panel mounted on the other surface of the first barrier; and a first insulation layer having multiple first insulation foams arranged on the other surface of the first panel for insulation. A corrugated plate is mounted between the first barrier and the first panel. The corrugation plate comprises: multiple wrinkles formed by absorbing the impact applied through the first barrier to damp the vibration; and combined wrinkles formed on the surface to be fitted in the wrinkles of the membranes. The present invention can increase a vibration isolation performance by absorbing the impact applied to the first barrier using the corrugated plate mounted between the first barrier and the first panel to damp the vibration; thereby increasing the safety of a cargo hold for an LNG carrier. Also, the present invention can have the simple configuration of the corrugated plate and can conveniently construct the corrugated plate.
