PURPOSE: A pressing board for pressing the corner of a secondary barrier in an LNG storage tank is provided to stably attach a triplex to a wall by completely sticking upper and lower adhesion plates to the wall. CONSTITUTION: A pressing board for pressing the corner of a secondary barrier in an LNG storage tank comprises a pair of upper adhesion plates (100, 101), a pair of lower adhesion plates (200, 201), and a connection part (300). The upper adhesion plates are horizontally separated from each other. The lower adhesion plates are arranged on the bottom of the upper adhesion plates. The connection part is installed between the upper and lower adhesion plates to connect the upper and lower adhesion plates to each other and has flexibility to rotate the upper and lower adhesion plates along the corner portions of a wall (10). |
