<p>PROBLEM TO BE SOLVED: To reduce the diagonal cutting face of a roof panel for a slant roof so as to simplify manufacturing. SOLUTION: In two parallel diagonals 30 to be arranged in the slant direction of a roof, both end faces are formed perpendicular to the material axis. Meanwhile, two parallel crosspieces 40H, 40L being at right angles to the diagonals 30 and connecting together the upper ends and the lower ends, are formed into trapezoidal sections of which one sides are diagonal. The four sides of the upper crosspiece 40H are formed out of four faces, opposed two faces 41H, 42H in parallel with each other and having different width, a squarely crossing standing side 43H, and an oblique side 44H slanted by the inclinationθof the roof and opposed to the standing side 43H, and while the standing side 43H is faced to the center side of a roof panel 10, the large width face 41H in the opposed two faces in contact with the panel face bar 50 to be fixed. The lower crosspiece 40L is fixed to it under the condition in which the upper crosspiece 40H is inverted.</p> |
