CARGO BARRIER STRUCTURE

A cargo hold barrier structure is disclosed. The cargo hold barrier structure, according to an embodiment of the present invention, comprises: an upper insulation board which is arranged in the bottom of a primary barrier and has an upper protection plate and an upper insulation member formed on the bottom surface of the upper protection plate; a secondary barrier which is arranged in the bottom of the upper insulation member; and a lower insulation board which is arranged in the bottom of the secondary barrier and has a lower insulation member and a lower protection plate formed on the bottom surface of the lower insulation member, wherein the upper insulation member has lower density than the lower insulation member. Therefore, the present invention provides the barrier structure considering the structural strength of the insulation board. 화물창 방벽구조가 개시된다. 본 발명의 실시 예에 따른 화물창 방벽구조는 1차방벽 하부에 배치되며, 상부보호판과 그 하면의 상부단열부재를 포함하는 상부단열보드; 상부단열부재 하부에 배치된 2차방벽; 및 2차방벽 하부에 배치되며, 하부단열부재와 그 하면의 하부보호판을 포함하는 하부단열보드를 포함하되, 상부단열부재는 하부단열부재에 비해 저밀도를 갖는다.
