<p><P>PROBLEM TO BE SOLVED: To easily and inexpensively construct a roof underlayer structure which exerts venting performance, and is excellent in heat insulation properties and high in strength. <P>SOLUTION: The venting performance of the roof underlayer structure is ensured by: arranging a plurality of heat insulation materials 3A each formed of a porous plate at intervals corresponding to a rafter width; connecting the heat insulation materials 3A to each other and reinforcing them by extending a slender reinforcing material 3B on the upper side of the heat insulation materials 3A and sticking them to each other: bonding a plurality of heat insulation plates 3 each having a rafter fitting portion 5 between the heat insulation materials 3A at a connection portion to the lower surface of a sheathing face plate 2 via the reinforcing material 3B; and securing vent paths 4 having thicknesses corresponding to that of the reinforcing material 3B in a space between the sheathing face plate 2 and the heat insulation material 3A, and at locations between the reinforcing materials 3B. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
