CONSTITUTION:In a panel 2, a corrugated steel plate 5 is attached to the inside of a steel frame 4 whose both sides are opened, and L-shaped angle parts 6 with bolt-fitting holes 7 are attached along the frame 4. The peripheral downside of a roofing panel 2 is placed on the upside of the wall panel 2, the angle parts 6 attached to the peripheral sides of the panels 2 are butted along a water-proof packing 8, and high-tensile bolts 9 are thrust through the bolt-fitting holes 7 of the angle parts 6. They are screwed and joined with nuts 10, and the wall panels and floor panels are also joined likewise. |
