Description

  The present invention relates to a building ventilation structural material used for forming a ventilation building on a roof.

  Conventionally, what is called a ventilation building is often provided in the ridge of the roof in order to prevent moisture and maintain a long life of the house by ventilating the attic. This ventilation building is formed in a mountain shape so as to be bent along, for example, a metal thin plate, and this ventilation building covers a ventilation opening provided in the roof building. The ventilation building is provided with a vent hole communicating with the ventilation port, thereby ensuring ventilation inside and outside the attic.

  However, if the ventilation holes are simply provided in the ventilation building, there is a risk that rainwater or the like may enter the indoors through the ventilation holes due to crosswinds or the like during strong winds. Thus, if rainwater or the like enters the indoors through the vent hole, the life of the house is shortened. For this reason, when providing a ventilation building, it is necessary to ensure the circulation of air inside and outside the attic and to prevent the inflow of rainwater.

  Therefore, for example, in the example shown in FIG. 5, the member 25 having a plurality of shielding plates 26 is provided on the roof side in which the purlin 15, the rafter 16, the field 17, the roofing material 19, and the like are combined, and A shielding plate 26 is also erected on the ceiling surface, and a vent hole 27 is provided on the upper surface of the wing 12 so that a complicated air path is formed in the ventilation wing and air circulation inside and outside is ensured. The inflow of rainwater etc. is prevented.

Further, Patent Document 1 discloses that a ventilation hole is further provided in a side portion of the ventilation building to prevent intrusion of rainwater or the like, and Patent Document 2 discloses a ventilation member having a porous member. What is made difficult to infiltrate rain water etc. by forming in is disclosed.
