Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to venting water draining when a dry wall material used as an exterior material starts to be stretched at the first stage.
[0002]
[Prior art]
Conventionally, as a drainer formed in a ventilation structure using a dry wall material, as shown in FIG. 10, a waterproof sheet E made of a windproof and moisture permeable sheet is applied on a housing C (a wooden base, a steel base, etc.) A drainage G is constructed between the ventilation trunk edge E and the foundation γ of the wall base α on which the ventilation trunk edge E is formed via the fixture β, and then the starter H is constructed with the fixture β. It was constructed by inserting the lower end of the dry wall material B. Of course, in this case, a gap a is formed between the base γ and the drainage G, and ventilation is performed through the gap a. In addition, a waterproof sheet D such as asphalt felt may be further formed on the ventilator edge E from the fixing part of the draining G, or an insect net made of stainless mesh or the like may be formed so as to cover the gap a.

[Problems to be solved by the invention]
However, it is necessary to take dimensions in the above-described drainage, and the work of forming the gap a is troublesome and takes time for construction. Moreover, since the dimension of the space | gap a is important for determining air flow, it had to be constructed with a certain dimension. Furthermore, if the size of the gap a is too large, insects (ants, bees, etc.), small birds, dust, etc. may invade from the gap a, and there is a risk of blocking the air passage or destroying the enclosure. It was. Of course, if the formation of the air gap a is insufficient, the performance of the air passage cannot be sufficiently exerted, and moisture remains in the inside of the housing, which causes corrosion of the housing, mold, and mites.
