PROBLEM TO BE SOLVED: To improve living environment of a small attic by tensely fitting sheathing roof boards tensely providing structural plywood of thickness capable of insuring fixed strength on both sides of a polystyrene foam board of proper thickness onto roof rafters. SOLUTION: Structural plywood is stuck on both sides of a lengthy polystyrene foam board through adhesive and the like. For example, pair-posts 7 are standingly provided on a level beam 6 and they are spanned with a doubling 8, a central post 9 is erected, a purlin 10 is loaded thereon, and a main house 12 is built on the doubling 8 and principal rafters 11. In addition, sheathing roof boards A omitting rafters are arranged on the purlin 10 and the main house 12 along the inclination of a roof. Inn this case, the sheathing roof board A is formed into a lengthy plate of 2×8 feet, and a connecting part is arranged on the short feet edge. Hereby, By the roof construction using the sheathing roof board A, the tensely providing work of the sheathing roof board A and a heat insulating work can be simultaneously executed, and hence the work can be simplified. |
