COUPLING STRUCTURE OF A REINFORCING MEMBER FOR A PRIMARY BARRIER OF AN LNG STORAGE TANK CAPABLE OF FIXING A REINFORCING MEMBER REINFORCING THE RIGIDITY OF THE CORRUGATION PORTION OF A PRIMARY BARRIER TO THE UPPER PART OF AN INSULATION BOARD

摘要

PURPOSE: A coupling structure of a reinforcing member for a primary barrier of an LNG storage tank is provided to stably fix a reinforcing member between an insulation board and a primary barrier by fixing the reinforcing member to the upper part of the insulation board.;CONSTITUTION: A coupling structure(30) of a reinforcing member for a primary barrier of an LNG storage tank comprises an elastic coupling unit(70), a hole(53), and a coupling groove(57). The elastic coupling unit is formed on the lower part of the reinforcing member. The hole is formed on the upper surface of an insulation board(50). The coupling groove is formed on the lower part of the hole. Since the elastic coupling unit is coupled to the coupling groove through the hole, the reinforcing member is fixed to the upper part of the insulation board.;COPYRIGHT KIPO 2012
