PRIMARY BARRIER REINFORCEMENT STRUCTURE OF LNG STORAGE TANK

摘要

PURPOSE: A reinforcing structure for a primary barrier of an LNG storage tank is provided to simplify an installation time period and installation processes for a primary barrier since after a reinforcing structure for the primary barrier is installed on the primary barrier without a fixing unit, the primary barrier is fixed to an insulating board. CONSTITUTION: A reinforcing structure for a primary barrier of an LNG storage tank comprises a first reinforcing member(110). The first reinforcing member is coupled to the lower part of a first corrugation portion of a primary barrier. The first reinforcing member comprises a first support(112), a first bottom portion(114), and a coupling portion(116). The first support supports the first corrugation portion and is extended along the extension of the first corrugation portion. The first bottom portion is formed on the lower part of the first corrugation portion. The coupling portion is extended from both ends of the first bottom portion and engages with the lower side of a crossing portion of the primary barrier.
