<p><P>PROBLEM TO BE SOLVED: To construct a building allowing the comfortable use of an attic space as a room in the building provided with a gable roof, while carrying out prefabrication. <P>SOLUTION: A top beam 7 is provided to connect the top parts of end direction walls 2a to each other. An intermediate part beam 8 is provided between the top beam 7 and the upper end part of a girder direction wall 6 supporting the roof orthogonally to the end direction wall 2a. An upper roof panel 9a is installed being supported to the top beam 7 and the intermediate part beam 8, and a lower roof panel 9b is installed being supported to the intermediate part beam 8 and the girder direction wall 6. The lower roof panel 9b is provided with rock wool 9b3 to exhibit heat insulating effect, but even in this case, air permeability is secured in the lower roof panel. Since heat is not kept inside the lower roof panel, nor does dew condensation or the like occur, the space of the attic can be used more comfortably. <P>COPYRIGHT: (C)2003,JPO</p> |
