<p>PROBLEM TO BE SOLVED: To prevent a support frame from opening during transportation or prevent joint holes of a room unit and the support frame from getting out of positions during installation by detachably fitting temporary beams preventing deformation during transportation to the support frame of a roof unit. SOLUTION: A roof unit 1 is constituted of constituting members 2 (roof tiles) of the roof face and a support frame 3 supporting the members. Detachable temporary beams 4 preventing deformation thereof during transportation are fitted to the support frame 3. The support frame 3 is constituted of gate-shaped gable frames 31 and girder trusses 33 laterally fitted to both upper ends of the gable frames 31. Diagonal members 32 are laid between the girder trusses 33 and the gable frames 31. Rafters are laid on rafter-receive members fitted to the girder trusses 33 and eaves beams, and constituting members 2 for the roof face are fitted on the rafters. The temporary beams 4 are fitted to the lower end of the gable frame 31 at one end thereof and the lower end of the girder truss 33 at the other end, and the fitting pieces are fixed to the support frame 3 of the roof unit 1 and the tension of the temporary beams 4 is adjusted by turnbuckles.</p> |
