[Fig. 6] is a side view showing a main part of a ventilation wing according to another embodiment of the present invention. FIG. 7 is a perspective view showing a main part of a ventilation building according to another embodiment of the present invention.

The ventilation building of the present invention, as shown in FIGS. 1 to 7, is a thin metal plate (1) having a substantially chevron cross section along the ridge portion of the roof surface, and an opening is formed in this thin metal plate (1). A plurality of ventilation openings (10) for discharging moisture-containing air from the attic (19), and a ventilation path (18) connecting the ventilation openings (10) and the attic (19) to allow the moisture-containing air to pass therethrough. ), And a foam material (6) that instantly foams and closes the ventilation passage (18) when it receives high heat.

The thin metal plate (1) is shown in FIGS.
As shown in FIG. 7 and FIG. 7, the cross section has a substantially chevron shape along the ridge portion of the roof surface. Various materials are used as the thin metal plate (1), for example,
A galvalume steel plate or the like can be used. This thin metal plate (1) is fixed using fixing nails (14) as shown in the figure.

If necessary, a drainer plate (9) may be provided on the roof surface to improve the waterproof property of the roof surface, or a metal sheet (1) may be attached to the roof plate so that the metal thin plate (1) can be easily fixed. 4) may be provided. Also,
As shown in FIG. 1 to FIG. 7, both ends of the metal thin plate (1) may be provided with downwardly directed pieces (16) extending downward for the purpose of further improving waterproofness. The continuous piece (13) may extend continuously from the lower end of the downward piece (16) toward the outside. Furthermore, as shown in FIG. 3 and FIG. 6, nail holes (12) may be provided at desired locations on the thin metal plate (1).

As shown in FIGS. 1 to 7, there are a plurality of ventilation holes (10), which are formed in the thin metal plate (1) to discharge air containing moisture from the attic (19). It is a thing. This ventilation port (10) is, for example, one in which the thin metal plate (1) is cut at a plurality of points and bent downward to form a louver shape, and each vane plate (5) has an arc shape as shown in the drawing. A part is formed in the ventilation port (10).
