<p>PROBLEM TO BE SOLVED: To provide a heat insulating panel where heat is completely isolated between a front surface material and a back surface material. SOLUTION: An intermediate part between a front surface material 10 and a back surface material 20, is connected by an intermediate part connection material 50 excellent in heat insulating properties, and an end part connection material 40 is mounted to each end part, so that an unit panel is thereby formed up. The unit panels for respective stages are piled up in the vertical direction so as to be fastened by a connection bolt 4, and an upper end connection material and a lower end connection material are thereby mounted to an upper end part and a lower end part respectively thereafter. Since the intermediate part connection material 50 allows the notches of the material and the notches of its partners to bite each other, it is prevented from falling out of the front surface material 10 and the back surface material 20. Since there exists no metallic connection part such as a rib and the like between the front surface side and the back surface side, therefore, the unit panel is formed into a heat insulating panel excellent in heat insulating properties.</p> |
