Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ventilation ridge device, and its gist is that a ridge roof portion 2 having a substantially inverted U-shaped cross section is provided on a pair of ridge beams 1 disposed parallel to the ridge direction. A ventilation hole 3 is opened in the side surface 2a of the ridge roof part 2, and a protection plate 5 is erected along both sides of the ridge roof part 2 in parallel with the outer surface of the ridge roof part 2. A ventilation gap 4 communicating with the ventilation opening 3 and opening upward is formed between the outer surface of the ridge roof portion 2 and the inner surface of the protection plate 5.
The ventilation building device is characterized in that a heat storage material 6 is provided on at least one of the outer surface of the protective plate 5 or the inner surface of the protection plate 5, and its purpose is to store solar heat in the heat storage material during the daytime. To provide a ventilation ridge device capable of warming and raising the surrounding air with this heat at night and promoting ventilation from the ventilation ridge.

The present invention will be explained in detail below with reference to the accompanying drawings. A pair of ridge beams 1 are placed on rafters 8 in parallel with the ridge beam 7. The space between one ridge pier is vented to the attic. A ridge roof part 2 having an inverted U-shaped cross section is placed on the ridge pier 1 over the entire length in the ridge direction, and the lower end edge 2c of the ridge roof part 2 covers the side surface of the ridge pier 1 and also covers the ridge. A ventilation hole 3 is opened in a side surface 2a of the roof portion 2. Reference numeral 9 denotes a fixing metal fitting 9 bent in a substantially inverted U shape. A nail 10 is driven from the lower end of the fixing metal fitting 9 through the ridge roof part 2 to the ridge beam 1, and the ridge roof part 2 and the fixing metal fitting 9 are attached to the ridge beam 1. It is fixed at The fixing fittings 9 are attached at approximately equal intervals along the ridge direction, and the ceiling surface 2b of the ridge roof portion 2 is pressed and held by the upper piece 9a of the fixing fitting 9. On both sides of the ridge roof part 2, protection plates 5 are arranged parallel to the side surfaces 2a of the ridge roof part 2 over the entire length in the ridge direction, and the inner surface of the protection plate 5 is screwed into the side vertical piece 9b of the fixing fitting. It is fixed at 11. Between the outer surface of the ridge roof part 2 and the inner surface of the protection plate 5, a ventilation gap 4 communicating with the ventilation port 3 and opening upward is formed over the entire length in the ridge direction. 6 is a thermal storage material such as a rubber sheet mixed with metal powder or a urethane sheet mixed with glass powder, which has a heat storage effect and a soundproofing effect at the same time. As shown in the figure, the heat storage material 6 is integrally provided on the inner surface of the protection plate 5 over its entire length and faces the gap 4.

Since the heat storage material 6 is fixed to the back surface of the protection plate 5 and the protection plate 5 has a heat storage function, the protection plate 5 heated by the sun during the day continues to retain heat even at night, and the gap The air in the gap 4 is heated to cause the air in the gap 4 to rise. The rise of the air in the gap 4 creates a negative pressure in the ventilation opening 3 to draw out the air inside the ventilation ridge, and the air inside the ventilation ridge is exhausted to the outside through the ventilation opening 3 as shown by the arrow in the figure. As a result, the air in the attic is efficiently ventilated. Moreover, the ridge roof part 2
Rainwater that has blown into the gap 4 between the ridge and the protective plate 5 will not be blown into the ridge roof part 2. Rainwater blown into the gap 4 is drained to the outside through drain holes (not shown) provided at appropriate locations in the protection plate 5.

Further, the heat storage material 6 may be provided on the outer surface of the ceiling surface 2b or both side surfaces 2a of the ridge roof portion 2.

As described above, the present invention includes a ridge roof section having a substantially inverted U-shaped cross section mounted on a pair of ridge beams arranged parallel to the ridge direction, a ventilation hole opened in the side surface of the ridge roof section, and a ventilation hole opened on the side surface of the ridge roof section. For ventilation, protective plates are erected parallel to the outer surface of the ridge roof along both sides of the roof, communicating with the ventilation opening between the outer surface of the ridge roof and the inner surface of the protection plate, and opening upward. Since a gap is formed and a heat storage material is provided on at least one of the outer surface of the ridge roof or the inner surface of the protection plate, the solar heat absorbed and stored in the heat storage material during the day is transferred to the heat storage material at night. The heat is radiated from the ridge roof to the gap between the roof ridge and the protective plate, and this radiated heat warms the air in the gap, creating an upward airflow from the gap to the outside air, which increases the air flow from the ventilation ridge to the attic. It has the advantage of being able to perform ventilation efficiently, does not use energy sources other than solar heat, and does not require running costs for forced ventilation.
