Te, covers the inclined surface shaped ceiling and a horizontal plane ceiling of the same or narrower and the building unit than the width of the building unit width 1
And a support member provided on the horizontal ceiling and supporting the roof panel in a state of being inclined along the inclined plane ceiling of the building unit, and a length dimension of the roof panel. L is a right angle in which the length dimension of the inclined planar ceiling portion in the direction of inclination is L ₁ , the longitudinal direction of the horizontal planar ceiling portion is the base, and the oblique side forms the same angle as the inclination angle of the inclined planar ceiling portion. When the length of the hypotenuse of the triangle is L ₂ and the length of the eave-side protrusion from the inclined surface ceiling is L ₃ , L = L ₁ + L ₂ + L ₃ .

[0008]

In the construction of the roof, after the building unit is installed, a supporting member is provided on the horizontal ceiling of the building unit, and one sheet of the sheet is formed along the sloped ceiling of the building unit via the supporting member . Support the roof panel in an inclined state. Then, since the single roof panel covers all of the inclined planar ceiling portion and the horizontal planar ceiling portion of the building unit, it is not necessary to perform raining at the building site. Therefore, work at heights due to the rain on the roof can be eliminated, and efficient work can be performed with less danger. Moreover, the roof panels, because they have eaves-side protruding length L ₃ from the inclined planar ceiling portion, out of the eaves can be secured.
