<p>PURPOSE:To lighten a roofing panel, to reduce the cost of production, and to improve the efficiency of construction, by a method wherein a framework is laid between a ceiling beam at the side of an outer wall and a support, rafters are arranged on the framework, and a sheathing roof board is placed on the rafters. CONSTITUTION:A framework 9 for a roofing panel 6 is laid between a ceiling beam 2b and a girder truss 5 for a partitioned unit building 3. Rafters 10, each eaves part 10a of which is elongated outward out of the framework 9, are arranged on the framework 9, and a sheathing roof board 11 is placed on the rafters 10, and thus the roofing panel 6 is lightened. Furthrermore, another framework 9 is laid between a ceiling beam 2b on the side of the outer wall of the box-shaped unit building 3 placed side by side and the girder truss 5 which is placed both on the ceiling beam 2a at the side opposed thereto and on the ceiling beam 2a adjacent thereto, and thus a load being imposed on the under building is lightened. In this way, the cost of production is reduced, safety is improved and the structure thereof can be simplified.</p> |
