The present invention provides an insulation wall fixing structure of a liquefied natural gas tank. The liquefied natural gas tank with a double barrier structure comprises a secondary insulation wall having a plurality of secondary insulation panels fixed to an inner wall of a hull, and a primary insulation wall having a plurality of primary insulation panels fixed to upper portions of the secondary insulation panels. The insulation wall fixing structure comprises: a corner fixing apparatus for fixing each corner part of the secondary insulation panels to the inner wall of the hull; and a center fixing apparatus installed to pass through the center of a secondary insulation panel, and fixing each corner part of the primary insulation panels to the inner wall of the hull. The secondary insulation panel is supported by mastic on the inner wall of the hull, while the mastic is applied between kraft paper laid on the inner wall of the hull and the secondary insulation panel. Therefore, the secondary insulation panel is supported in a non-adhesive manner on the inner wall of the hull.

    본 발명은 선체 내벽에 고정되는 다수의 2차 단열패널로 이루어지는 2차 단열벽과, 2차 단열패널의 상부에 고정되는 다수의 1차 단열패널로 이루어지는 1차 단열벽을 포함하는 이중 방벽 구조의 액화천연가스 저장탱크에 있어서, 2차 단열패널의 각 코너부를 선체 내벽에 고정시키는 코너 고정장치; 및 2차 단열패널의 중심부를 관통하여 설치되며, 1차 단열패널의 각 코너부를 선체 내벽에 고정시키는 센터 고정장치를 포함하며, 2차 단열패널은 선체 내벽에 매스틱(mastic)에 의해 지지되되, 매스틱은 선체 내벽에 깔리는 크라프트지(kraft paper)와 2차 단열패널 사이에 도포되어, 2차 단열패널이 선체 내벽에 비접착식으로 지지되는 것을 특징으로 하는, 액화천연가스 저장탱크의 단열벽 고정구조를 제공한다.
