APPARATUS OF PRESSING CORNER PART OF 2ND BARRIER OF LNG CARGOCONTAINMENT

摘要

A corner part pressing tool of the LNG storage tank second barrier is provided, in which the uniform pressure can be applied to the triplex regardless of the curvature change of the wall edge portion. A corner part pressing tool of the LNG storage tank second barrier comprises: pressurized panels(120,130) having the first main adhesive plate and the second main adhesive plate; and a pressure unit(150) which is installed in order to move about frame and pressurizes the pressurized panel. To the inside of the storage tank wall(200), heat-insulating panels(210) are adhered. The triplex(230) is welded between heat-insulating panels. The elastic layer(112) formed with the elastic materials is welded to the front side of the intimate panel. The base plate adheres closely to the triplex. The pressurized panel is rotated as the bent angle of the edge portion of the wall changes.
