PURPOSE:To provide the subject structure so designed that inner side of a transparent film or plate forming the ceiling is provided, apart therefrom, with a transparent fluororesin film for lining use in a stretched fashion, thereby preventing water droplets form dropping caused by water vapor condensation on the ceiling on the crop. CONSTITUTION:A nearly mountain-shaped house skeleton formed by combination of a skeletal material 1 constituting the support with a second skeletal material 2 supporting the ceiling is provided with a transparent film or plate in a stretched fashion to form a ceiling part 3. This ceiling part 3 is then supported by iron skeletal members 4 with the sectional shape given in the figure, and a transparent fluororesin film 5 for lining use is applied on the lower surface of said members 4 in a stretched fashion and intermittently put firmly with magnets 6 in a sandwiched manner to effect fixation. |
