PURPOSE: A coupling structure of a reinforcement member for a primary barrier in an LNG storage tank is provided to fix a reinforcement member for reinforcing the strength of corrugations on a primary barrier to the top of an insulation board. CONSTITUTION: A coupling structure of a reinforcement member for a primary barrier in an LNG storage tank comprises an elastic coupling part (70), a hole (53), and a coupling groove (57). The elastic coupling part is formed using the same material as a reinforcement member (30) and is formed on the bottom of the reinforcement member. The elastic coupling part comprises an extension part (71) and a fastening part. The fastening part is protruding from the extension part and is fixed to the top of an insulation board (50). The hole is formed on the top surface of the insulation board. The coupling groove is formed under the hole. |
