Document Type and Number:
Japanese Patent JP3240922
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To increase the fireproof property, by providing a plurality of ventilation openings formed with metallic thin plates having a nearly chevron-shaped section and extended along the ridge of the roof face to exhaust air including moisture from the attic and an air passage connecting the ventilation opening and the attic to let air with moisture through and also providing a foaming material foams instantaneously to shut the air passage when it is heated in a high temperature.
SOLUTION: This device is provided with a plurality of ventilation openings 10 foamed with metallic thin plates having a nearly chevron-shaped section and extended along the ridge of the roof face to exhaust air including moisture from the attic 19 and an air passage 18 connecting the ventilation opening and the attic to let air with moisture through. The foaming material 6 foams instantaneously to shut the air passage when it is heated in a high temperature and the foaming material 6 is chiefly made of epoxy resin, polyphenylene foaming material, vinylchloride resin, polyethylene foaming material, polyisocyanurate foaming material, etc.
