The fixture 65 also serves to fasten the eaves top plate 61 . By fastening the eaves top plate 61 to the ceiling joist 60 together with the inner mounting plate material 16 with the fixture 65, the eaves top plate 61 is fixed more firmly, and the eaves top plate 61 is less likely to burn down in the event of a fire. Better performance.
In addition, since the second extending plate member 15 of the ventilation member 10Z is inclined with respect to the outer mounting plate member 12, the second extending plate member 15 is more likely to move away from the ventilation hole 11a than the case where the second extending plate member 15 is parallel to the outer mounting plate member 12. The width of the ventilation path leading to the inside of the attic is narrowed. As a result, it is possible to reduce hot air entering the attic through the ventilation holes 11a. In addition, although the thickness of the eaves top plate 61 varies depending on the fire resistance grade, by inclining the second extension plate member 15, the eaves top plate 61 of various thicknesses can be supported by the second extension plate member 15. . FIG. 9(a) shows a case where an eaves top plate 61 thicker than the eaves top plate 61 shown in FIG. 9(b) is used. In addition, in FIG. 9(b), the space between the eaves top plate 61 thinner than the eaves top plate 61 in FIG.

A noncombustible heat insulating material 80 is arranged above the thermal expansion material 20 . A building fascia base 56 is placed above the noncombustible heat insulating material 80 . By arranging the incombustible heat insulating material 80 between the fascia base 56 and the thermal expansion material 20, the thermal energy of the expanded thermal expansion material 20 can be insulated so as not to be transmitted to the fascia base 56.例文帳に追加

The ventilation members 10X, 10Y, and 10Z according to the present invention are preferably constructed so that the lower end of the inner draining board 18 is located above the lower end of the fascia 57 or the gable board 69. By locating the lower end of the inner draining plate material 18 at the same level as or higher than the lower end of the fascia 57 or the gable plate 69, especially the rainwater that blows horizontally from the outside can be prevented from The plate 69 allows rainwater to fall downward, preventing rainwater from entering through the ventilation holes 11a. Rainwater can be prevented from entering from 11a.

According to the present invention, since the inner draining plate member 18 is provided inwardly of the ventilation hole forming plate member 11, it is possible to prevent the rainwater blown in from the horizontal direction from entering through the ventilation hole 11a.

INDUSTRIAL APPLICABILITY The present invention is suitable as a ventilation member to be attached to eaves and vaults.
