REINFORCEMENT STRUCTURE FOR PRIMARY BARRIER OF LNG STORAGE TANK

摘要

PURPOSE: A reinforcement structure for a primary barrier of a LNG storage tank is provided to prevent scratches in a primary barrier when a coupling portion of a first reinforcement member is inserted into a crossing portion of the primary barrier. CONSTITUTION: A reinforcement structure for a primary barrier of a LNG storage tank includes a first reinforcement member(110) which is coupled to the lower part of a first corrugation portion of a primary barrier. The first reinforcement member comprises a pair of coupling reinforcement members(120) and a connection member(140). Coupling pieces(126) are formed in one end of the coupling reinforcement members and coupled to the lower part of a crossing portion of the primary barrier by shape fitting. The connection member connects the other end of the reinforcement member.
