There are cases of adoption.
[0003]
In this ventilation method, as the ventilation structure of the wall that is formed between the upper part of the outer wall and the ceiling, in particular, the eaves ceiling, for example, JP-A-8-13636 (first known technique), Japanese Utility Model Laid-Open No. 6-78414 (second known technology) or Japanese Patent Application Laid-Open No. 11-22042 (third known technology) is known.
[0004]
In the first known technology, a parting member is provided which has an exhaust port on the outdoor side reverse inclined surface of a rectangular tube formed by bending a metal plate and an air inlet on an upright surface on the indoor side. A ventilation layer provided in the wall frame, which is constructed by attaching an elastic parting joiner into the gap between the lower surface of the parting member and the outer wall, and being attached to the side of the part of the eaves ceiling formed between the part and the outer wall. This is a technology of a ventilation parting structure that exhausts the air inside.
[0005]
In the second known technique, a fire-resistant foaming material is provided that has a ventilation interval between the wall base structure and the wall plate, and can foam when reaching a predetermined high temperature at openings above and below the ventilation interval. Ventilation configured to prevent fire and hot air from entering the room by foaming the fire-resistant foam and closing the opening of the ventilation interval when a fire occurs. It is a technology related to the fire prevention structure of the wall.
[0006]
Further, the third known technique provides a ventilation space between the outer wall and the wall base material, forms a ventilation passage communicating with the ventilation space between the eaves ceiling plate and the outer wall, and faces the ventilation passage.
