<p>PROBLEM TO BE SOLVED: To provide a roof easy in the rigidity balance with a lower floor; and easy in a building work. SOLUTION: The roof includes an attic space building unit 50 arranged on a building body 3, a face-shaped attic space panel 60 arranged on both sides of this attic space building unit 50 to constitute a floor of a living room, and a roof panel stretched to and supported by the attic space panel 60 and the attic space building unit 50. The number and kind of components such as columns and beams are reduced, the manufacturing work is simplified, and the building work of the roof is facilitated. Since a truss comprises the roof panel 40, the attic space panel 60 and the attic space panel 50, the rigidity of the roof part is ensured. Also, since the attic space panel 60 has no columns, an attic space part 5 is balanced in rigidity with a building body 3, and thus, the balance in rigidity between the roof and the lower floor can be easily realized.</p> |
