Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage device for a dry wall material used as an exterior material when the first step is started.

[0002]

2. Description of the Related Art Conventionally, as a drainer formed into a ventilation structure by using a dry wall material, as shown in FIG. 11, a waterproof sheet D composed of a windproof and moisture-permeable sheet on a frame C (wooden foundation, steel frame foundation, etc.) is used. , And draining G is carried out between the ventilation rim E and the foundation γ of the wall foundation α on which the ventilation rim E is formed via the fixing tool β, and then the starter H is mounted with the fixing tool β Then, the lower end portion of the dry wall material B is inserted into the starter H for construction. Of course, in this case, a gap a was formed between the foundation γ and the drainer G, and ventilation was performed through the gap a. Further, a waterproof sheet D such as asphalt felt may be further formed on the ventilation shell E from the fixing portion of the drainer G, or an insect repellent sheet made of stainless mesh or the like may be formed so as to cover the gap a.

[0003]

However, in the case of the above-mentioned drainage, it is necessary to take dimensions, and the work of forming the gap a is troublesome and takes a long time for construction. In addition, since the size of the gap a is important in determining the amount of ventilation, it must be performed with a certain size. Further, if the size of the gap a is too large, the gap a
Insects (ants, bees, etc.), small birds, garbage, etc., enter, and there is a danger of blocking the ventilation path and destroying the skeleton. Of course, if the gap a was insufficiently formed, the performance of the ventilation path could not be sufficiently exhibited, and moisture remained in the inside of the skeleton, thereby causing corrosion of the skeleton, mold, and mites.

[0004]

SUMMARY OF THE INVENTION In order to eliminate the above-mentioned drawbacks, the present invention provides a water drainage formed at the lower end of a ventilation shell edge. By having a bent bottom surface, a ventilation gap formed at a constant pitch in the bottom surface, a locking piece projecting upward at the bottom end, and a draining surface bent at the bottom end inclined downward outward. It is another object of the present invention to provide a ventilation drainer which eliminates the above disadvantages.
