<p>PROBLEM TO BE SOLVED: To provide a frame for roof panels of a building that eases welding work and helps carry out accurate roof panel mounting. SOLUTION: In a frame 10 for a roof panel to support the roof panels 5, the connection of diagonal materials 14 and 24 with the first intermediate materials 15 and 25 is carried out by cutting diagonally the ends of the intermediate materials 15 and 25, and welding the cut sides to the undersides of the diagonal materials 14 and 24. As the ends of the intermediate materials that butt diagonal materials are cut diagonally in the direction of departure from the undersides of the diagonal materials, spaces between the cut sides and the undersides of the diagonal materials are formed widely, welding is facilitated, and welding work for connecting the diagonal materials with the intermediate materials crossing them is made easy.</p> |
