PURPOSE:To facilitate the working of a ceiling, by a method wherein a rectangular frame body is formed of wooden bar members so as to be in lattice form in longitudinal direction, one side of this frame body is made in flat mesh form and the other side thereof is covered with thermally insulating material. CONSTITUTION:Long band plate-like wooden bar members 20 located in parallel so as to face to each other are located in lattice form, and the both end parts of each of these members 20 are connected and fastened to short wooden bar members 21, and thus a frame body 2 is formed. After that, on one side of the frame body 2, wooden bar members 22 for reinforcement are located so as to intersect perpendicularly in longitudinal direction and the one side of the frame body 2 is made in flat mesh form. The other side thereof is covered with thermally-insulating material 3 and thus a ceiling panel 1 is formed. Therefore, the excellent effect of thermal insulation can be obtained. |
