DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drain structure for covering a lower end of a dry wall material used as an interior material or an exterior material.

[0002]

2. Description of the Related Art As a drainer C for covering a lower end portion of a conventionally used dry wall material B, FIG.
In a house as shown in (b), as shown in FIG. 15, a fixture β is used between a wall foundation α (made of a wooden foundation, a steel frame foundation, a waterproof sheet, or an existing wall, etc.) and a foundation γ. Met.

[0003]

However, in the wall using the drainer C as described above, a gap a is formed between the end of the drywall B and the drainage C, and rainwater or the like enters the interior. There was a disadvantage. Further, in the case of a composite structure (sandwich structure, canapé structure) in which the dry wall material B has a synthetic resin foam as a core material, the synthetic resin foam having a water absorbing property absorbs rainwater and the core material has a wet cloth. It became tattered and could not maintain the initial performance (insulation properties, fire protection, etc.).

[0004]

SUMMARY OF THE INVENTION In order to eliminate such drawbacks, the present invention provides a vertically flat fixing portion, a bottom surface having a lower end bent at an acute angle with respect to the fixing portion, and a bottom surface. Water holes formed at a constant pitch at the lower end of the cover piece, a cover piece with the bottom end bent inward substantially in parallel with the fixing portion, a side cover piece with the cover tip bent inward, and a lower end of the cover piece The above-mentioned drawbacks are caused by fixing the drainer formed from the lower cover piece projecting downward to the wall base horizontally and inserting the dry wall material into the space surrounded by the fixing part, the bottom surface and the cover piece. The present invention provides a drainage structure that eliminates water.

FIG. 4 is a cross-sectional view showing a construction state of the dry wall material B.

As shown in FIGS. 2 (a) to 2 (c), the drainer A is provided with a vertically flat fixing portion 1 and a lower end of the fixing portion 1 inwardly.
A mounting surface 2 bent in a letter shape, a bottom surface 3 formed by bending the lower end of the mounting surface 2 inward and being inclined, a flowing water hole 4 formed in the bottom surface 3 at a constant pitch, and a tip of the bottom surface 3 A cover piece 5 bent inward substantially in parallel with the fixing portion 1, a side cover piece 6 bent at the tip of the cover piece 5 inward, and a lower cover piece 7 formed by hanging the lower end of the cover piece 5 downward. , The lower end of the fixing portion 1 is further suspended downward, and is formed from a draining surface 8 which is bent outward.

[0007] The fixing part 1 is a fixing tool β with a drainer A on a wall base α.
It is a part fixed by.

The mounting surface 2 is formed with a step on the bottom surface 3 as shown in FIG. The dry wall material B is formed so that the dry wall material B does not absorb rainwater that has entered the inside without contact.

In the bottom surface 3, water holes 4 are formed at a constant pitch and are formed at an acute angle with respect to the fixed portion 1. The water holes 4 penetrate from between the dry wall material B and the side cover pieces 6 of the drainer A. It discharges rainwater that has drained out. The forming pitch P is about 30 to 300 mm.

The cover piece 5 is a portion that covers the lower end of the dry wall material B.

The side cover piece 6 is a decorative surface 9a of a dry wall material B.
To prevent the formation of a gap between the dry wall material B and the drainer A, thereby improving the aesthetics and waterproofness.

Further, the lower cover piece 7 is for covering the upper end of the dry wall material B with the foundation γ present at the lower part.

The draining surface 8 is for preventing rainwater and the like flowing down from the drain hole 3 from adhering to the foundation γ in the figure, and is used to prevent the dry wall material B from coming to the bottom. When formed at the seam between the first floor and the second floor (intermediate draining part), it covers the upper edge of the lower drywall B and allows rainwater to penetrate into the core of the lower drywall B. It is for preventing.

The material may be a metal sheet, for example, iron,

The core material 11 is, for example, polyurethane foam,
Polyisocyanurate foam, phenol foam,
It is made of synthetic resin foam such as vinyl chloride foam, polyethylene foam, polystyrene foam, urea foam and the like. For example, a stock solution of resole-type phenol, a curing agent and a foaming agent are mixed, and a surface material 9 or a back material 10 And heated, reacted, foamed, and cured to form. In the core material 11, lightweight aggregates (pearlite, glass beads,
Gypsum slag, talc stone, shirasu balloon, aluminum hydroxide, etc.), fibrous materials (glass wool, rock wool,
Carbon fiber, graphite, etc.) can be mixed to improve fire resistance.

More specifically, the core material 11 mainly functions as a heat insulating material, a fireproof material, an adhesive, a reinforcing material, a cushioning material, a sound absorbing material, a bulking material, a lightening material, and the like. Of course, an inorganic material such as rock wool, glass wool, or ceramic wool may be used as the core material 11.

Further, a sealing material may be formed between the dry wall material B and the drainer A to enhance waterproofness. As the material, for example, as a fixed and elastic sealing material, for example, foamed rubber, polyvinyl chloride,
Commercially available products such as chloroprene type, chlorosulfonated polyethylene type, ethylene propylene type, asphalt-impregnated polyurethane type, EPM, EPDM and the like, or silicone type as a curable sealing material (reaction curable type, moisture curable type) ), Modified silicone (reaction curing type), polysulfide (reaction curing type), polyurethane (reaction curing type, moisture curing type), SBR type (dry curing type), acrylic (dry curing type), etc. It is useful mainly as a function of a waterproof material, an airtight material and the like.

[0026]

As described above, according to the drainage structure according to the present invention, rainwater that has flowed into the water hole quickly drains out. Due to the formation of the cover pieces, the lower end of the dry wall material fits nicely. The side cover pieces are always in contact with the decorative surface of the dry wall material, and have good aesthetics. Since the bottom surface is formed to be inclined inward at an acute angle with respect to the fixing portion, it is possible to reliably discharge rainwater or the like that has entered the inside to the outside. Since the lower cover piece is formed, it is possible to cover a dry wall material, a foundation, and the like existing below. When a step is formed on the bottom surface (a mounting surface is formed), the drywall material does not come into contact with the rainwater that has penetrated inside, and the drywall material is made of synthetic resin foam when the core material is a synthetic resin foam. It is effective in preventing corrosion of the resin foam, preventing deterioration of heat insulation due to slimy cloth, prevention of corrosion of wall foundation, and prevention of reduction in strength of dry wall material. There are features and effects such as.
