COMBINATION STRUCTURE OF REINFORCING MEMBER FOR PRIMARY BARRIER OF LNG STORAGE TANK

摘要

PURPOSE: A coupling structure of a reinforcing member for a primary barrier of an LNG tank is provided to stably fix a reinforcing member between an insulating board and a primary barrier by fixing the reinforcing member to the upper part of the insulating board. CONSTITUTION: A coupling structure of a reinforcing member(30) for a primary barrier of an LNG tank comprises a stopping unit(70), a hole(53), and a groove(57). The stopping unit is formed on the lower part of the reinforcing member. The hole is extended on an insulating board(50) in at least one direction. The groove is formed on the lower part of the hole. If the reinforcing member moves horizontally to the insulating board, the stopping unit is slidably coupled to the hole and the groove.
