INSULATION PANEL AND LNG STORAGE TANK HAVING THE SAME, METHOD FOR CONSTRUCTION OF THE INSULATION PANEL

摘要

PURPOSE: An insulation panel and an LNG(Liquid Natural Gas) storage tank including the same, an insulation panel construction method are provided to maximize thermal insulation by removing the need of fastener holes. CONSTITUTION: An insulation material(33) thermally isolates a storage space. A protective plate(21) is integrally connected to the insulation material and has fastening grooves(22) extended from the side to the inside. A connecting member(25) is fixed to an inner wall by being coupled with the fastening grooves and a bracket fixed to the inner wall. A fastener is positioned in the fastening grooves to fasten the connecting member to the protective plate. The fastening grooves include a deep groove and a shallow groove. A projection(23) is formed between the deep groove and the shallow groove to catch the connecting member.
