Description

ＬＮＧ저장탱크 2차방벽 코너 압착용 가압보드{Pressing board for 2nd barrier of LNG cargocontainment}Pressing board for 2nd barrier of LNG cargocontainment}

본 발명은 LNG저장탱크 2차방벽 코너 압착용 가압보드에 관한 것으로서, 보다 상세하게는 LNG저장탱크 코너부분의 2차방벽용 단열패드 사이에 접합된 트리플렉스를 균일하게 가압할 수 있게 하는 LNG저장탱크 2차방벽 코너 압착용 가압보드에 관한 것이다.The present invention relates to an LNG storage tank pressurizing board for secondary barrier corner crimping, and more particularly, an LNG storage tank for uniformly pressurizing the triplex bonded between the insulation pads for the secondary barrier at the corner of the LNG storage tank. The present invention relates to a pressure barrier board for secondary barrier corner pressing.

일반적으로, 액화천연가스 운반선은 천연가스(LNG)를 에너지자원으로 활용할 수 있도록 상기 천연가스를 영하 162℃이하로 냉각하여 액체상태로 저장한 후, 생산지로부터 수용지의 인수지까지 대량으로 수송하게 된다.In general, liquefied natural gas carriers use natural gas (LNG) as an energy resource to cool the natural gas below minus 162 ° C, store it in a liquid state, and transport it in bulk from the production site to the receiving point of the receiving site. do.

그런데, 멤브레인형 액화천연가스 운반선의 경우 액화천연가스의 초저온에 의해 선박의 주재료인 강재가 작은 충격에도 균열이 생기거나 부서질 수 있는 바, 액화천연가스를 저장한 저장탱크는 단열이 이루어지도록 단열재로 단열처리한다. 더불어, 상기 액화천연가스 저장탱크 내부에 1차 방벽인 멤브레인에 크랙이 형성되어 액화천연가스가 누출될 경우, 이 가스가 선체 내벽(Inner hull)에 닿는 것을 방지하도록 2차 방벽을 형성한다. 상기 2차 방벽은 선체 내벽에 적정크기의 단연패널을 수지성 접착제로 부착한다. 그리고, 상기 단열패널 사이 공간에는 글래스 울(Glass wool) 같은 플랫조인트가 삽입 충진되고, 플랫조인트를 중심으로 단연패널 사이 상부 공간에 트리플렉스를 수지성 접착제로 부착하여 형성한다.However, in the case of membrane type LNG carriers, the steel, which is the main material of the vessel, may be cracked or broken even by a small impact due to the ultra low temperature of the LNG. The storage tank storing the LNG is insulated so that insulation is performed. Insulate with. In addition, a crack is formed in the membrane which is the primary barrier inside the liquefied natural gas storage tank, and when the liquefied natural gas leaks, the secondary barrier is formed to prevent the gas from contacting the inner hull. The secondary barrier is attached to the inner wall of the hull by the appropriate size of the far-end panel with a resin adhesive. In addition, a flat joint such as glass wool is inserted and filled in the space between the heat insulation panels, and the triplex is attached to the upper space between the far panels with a resin adhesive around the flat joint.

이때, 트리플렉스가 견고하게 부착될 수 있도록 코너부분의 경우 코너의 곡률에 대응되게 절곡된 합판을 이용하여 가압시키는 방식이 주로 사용되고 있다. 즉, 상기 합판을 코너에 부착된 상기 트리플렉스에 밀착되도록 상기 2차 방벽에 밀착 배치시킨 후, 가압장치에서 발생된 가압력이 상기 합판을 통해 상기 트리플렉스로 전달되면서 안정적인 접착상태를 유지되게 한다.At this time, in the case of the corner portion so that the triplex can be firmly attached to the pressing method using a plywood bent corresponding to the curvature of the corner is mainly used. That is, after the plywood is placed in close contact with the secondary barrier to be in close contact with the triplex attached to the corner, the pressing force generated in the pressurizing device is transferred to the triplex through the plywood to maintain a stable adhesive state.

그러나, 종래의 상기 합판은 코너의 곡률 변동에 따라 원활하게 변형되지 않음으로써 상기 트리플렉스에 균일한 가압력이 전달되지 않으면서 상기 트리플렉스의 안정적인 접착이 이루어지지 못하는 문제점이 있다.However, the conventional plywood is not smoothly deformed according to the curvature variation of the corner, and thus there is a problem in that stable bonding of the triplex is not achieved without uniform pressing force being transmitted to the triplex.

본 발명은, 트리플렉스가 접합된 저장탱크 코너부분의 단열패드 사이에 곡률에 대응되게 변형되면서 가압장치로부터 전달되는 가압력을 트리플렉스에 안정적으로 전달할 수 있게 하는 LNG저장탱크 2차방벽 코너 압착용 가압보드를 제공하는데 목적이 있다.According to the present invention, the LNG storage tank pressurizes the second barrier corner crimp that enables the triplex to be stably transmitted to the triplex while being deformed to correspond to the curvature between the insulating pads of the corner portion of the storage tank to which the triplex is bonded. The purpose is to provide a board.

본 발명은, 가압장치로부터 가압력을 전달받아 LNG저장탱크 벽체의 코너부분에 접착된 트리플렉스를 밀착 가압되게 하는 LNG저장탱크 2차방벽 코너 압착용 가압보드에 있어서, 수평방향으로 상호 이격 배치되는 한 쌍의 상부밀착판, 상기 상부밀착판에 대향되도록 하부에 배치되는 한 쌍의 하부밀착판, 상기 상부밀착판 및 상기 하부밀착판을 상호 연결하도록 상기 상부밀착판 및 상기 하부밀착판의 사이에 결합 설치되며, 상기 상부밀착판 및 상기 하부밀착판이 상기 벽체 코너부분의 굴곡에 대응되게 회동할 수 있도록 연성을 가지는 연결부를 포함하는 LNG저장탱크 2차방벽 코너 압착용 가압보드를 제공한다.The present invention, in the LNG storage tank pressure barrier for pressing the secondary barrier corner crimping pressurized pressure from the pressurizing device to tightly press the triplex adhered to the corner portion of the LNG storage tank wall, so as to be spaced apart from each other in the horizontal direction A pair of upper contact plates, a pair of lower contact plates disposed below to face the upper contact plates, coupling between the upper contact plate and the lower contact plate to interconnect the upper contact plate and the lower contact plate Installed, the upper contact plate and the lower contact plate provides a pressurized board for LNG storage tank secondary barrier corner pressing including a connecting portion having a flexible so as to rotate corresponding to the bending of the corner of the wall.

또한, 상기 상부밀착판 및 상기 하부밀착판의 상기 벽체에 대향되는 면부에는, 전도성 및 연성을 가지는 히팅패드가 더 결합 구비될 수 있다.In addition, a heating pad having conductivity and ductility may be further provided at a surface portion of the upper contact plate and the lower contact plate that faces the wall.

또한, 상기 히팅패드의 상기 벽체에 대향되는 면부에는 탄성을 가지는 쿠션패드를 더 결합 구비할 수 있다.In addition, the surface portion of the heating pad facing the wall may be further provided with a cushion pad having elasticity.

또한, 상기 연결부는 고무재질 또는 연성을 가지는 합성수지일 수 있다.In addition, the connection portion may be a synthetic resin having a rubber material or softness.

At this time, the upper contact plate (100, 101) and the lower contact plate (200, 201) is rotated correspondingly in the horizontal and vertical direction by the connecting portion 300 in accordance with the bending of the corner portion of the heat insulating panel (11). The triplex 20 attached to the heat insulation panel 11 in a state of being completely in contact with the (11) to be attached while pressing.

이와 같이, 일실시예의 상기 LNG저장탱크 2차방벽 코너 압착용 가압보드는, 상기 가압장치로부터 전달된 가압력이 연성을 가지는 상기 연결부(300)에 의해 연결된 상기 상부밀착판(100,101) 및 상기 하부밀착판(200,201)으로 전달되는 바, 상기 연결부(300)에 의해 상기 상부밀착판(100,101) 및 상기 하부밀착판(200,201)이 상기 벽체(10)의 코너부분 굴곡에 따라 대응되게 회동하면서 상기 벽체(10) 상에 완전 밀착되면서 상기 트리플렉스(20)를 상기 벽체(10)에 안정적으로 부착되게 한다.As described above, the LNG storage tank secondary barrier corner pressing board of one embodiment, the upper contact plate (100, 101) and the lower contact closely connected by the connecting portion 300 is a pressing force transmitted from the pressurizing device is flexible. Bars 200 and 201 are transferred to the plates 200 and 20, and the upper contact plates 100 and 101 and the lower contact plates 200 and 201 rotate correspondingly according to the bending of the corner portions of the wall 10 by the connection part 300. The triplex 20 is stably attached to the wall 10 while being fully intimately attached onto the wall 10).
