PROBLEM TO BE SOLVED: To provide a ceiling supporting structure which ensures the heat insulation property thereof between the interior of a room and an attic space, and can prevent occurring of condensation. SOLUTION: A ceiling beam 6 is formed by providing a metallic shape 4 which consists of an upper side portion 1, a lower side portion 2, and an intermediate portion 3, and is shaped like the H in cross section, and fixing woody materials 5 onto outer surfaces of the upper side portion 1 and the lower side portion 2. Then, upper plates 8 forming a ceiling panel 7 are arranged and mounted on both sides of an upper surface of the woody material 5 on the upper side portion 1 of the ceiling beam 6 such that a gap 9 is formed between side edges of the respective upper plates 8. Further, a heat insulating member 10 is mounted on side ends of the upper plates 8 arranged side by side, and a projection 11 projected from a lower surface of the heat insulating member 10 is engaged with the gap 9. |
