DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof exterior structure found on a base, an upper opening (upper window), and an intermediate joint (joint) when a wall of a building or a building is formed by using a dry wall material. Things.

[0002]

2. Description of the Related Art Conventionally, an exterior structure found on a base portion of a wall, an upper portion of an opening, or an intermediate joint is formed by simply forming a thin metal plate into a crank-like shape formed of a fixing piece, a water cutting piece, and a decorative piece. In addition, a structure in which dry wall materials are laid was common.

[0003]

However, in the structure formed as described above, the draining material lacks strength, and the draining material is fixed between the dry wall material and the fixing piece of the draining material, and the draining material is fixed to the base material. Rainwater, etc. easily enters the base material from the head of the fixing tool, etc., and corrodes the skeleton, heat insulating material (glass wool, gypsum board, etc.), dry wall material, foundation, etc. There were many drawbacks in the upper part, etc., which caused rain leakage.

[0004]

SUMMARY OF THE INVENTION In order to eliminate such disadvantages, the present invention provides a plurality of soft and elastic pieces on a fixed piece of draining material formed in a crank shape from a fixing piece, a water piece and a decorative piece. A waterproof sheet with protruding rain return pieces is laid, and the back of the dry-wall material adheres tightly to the rain return pieces of the waterproof sheet, and the rain return pieces provide multiple layers of waterproofing. It proposes a structure without any problems.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of an outer waterproof structure according to the present invention. FIG. 1 is an explanatory view showing a structure of a joint portion which is a typical example of the above structure, and is a structure including a drainer A, a waterproof sheet B, a dry wall material C, a base material α, and a fixing tool β.

That is, as shown in FIG. 2, the drainer A is made of a color steel plate, a stainless steel plate, an aluminum alloy plate, a titanium plate,
Metal sheets such as copper sheets, clad steel sheets, vibration damping steel sheets, PVC steel sheets,
Or a roll, press, extrusion, or injection molding of a synthetic resin plate, or a cement plate, a calcium carbonate plate, a calcium silicate plate, a ceramic plate, a wood chip cement plate, a magnesium carbonate plate, or the like, or glass fiber, whisker, or aramid fiber A mixture of steel fiber, carbon fiber, various mineral fibers, various aggregates, etc., formed by extrusion molding, press molding, injection molding, papermaking, etc., or weaving various fibers into a cross-shaped or three-dimensional shape, It is obtained by steam-curing or firing a material impregnated with cement, clay or the like.

The shape is such that a vertical fixing piece 1 and a water piece 2 bent at the lower end of the fixing piece 1 at about θ = 90 ° to 165 °.
And a decorative piece 3 in which the tip of the water piece 2 is bent downward to form a long shape. As shown in FIG. 1 showing the structure of the joint portion, the fixing piece 1 is a portion to be fixed to a base material α via a fixing tool β such as a nail, and also a portion to lay a waterproof sheet B described later.

[0008] Water section 2 is a portion for preventing the lower end of the upper drywall material C ₁ as shown in FIG. 1 the rainwater from entering the interior base material alpha, the inclination angle theta 90 ° From 1
The range is up to about 65 °. This is 90 °
If it is less than 165, water pools may be formed.
° If you above, the upper gap between the lower and the water section 2 of drywall material C ₁ (joint width) becomes too large, there is a fear that impair the design property.

As shown in FIG. 1, the decorative piece 3 covers the upper part of the lower dry wall material C ₂ to improve the design, and
In which rainwater is prevented from entering the interior base material α from above of the drywall material C ₂ in the lower. In the drawing, the lower end of the decorative piece 3 is folded inwardly in an L-shape to form a reinforcing portion 3a for draining water and improving the strength of the decorative piece 3.

The waterproof sheet B is made of, for example, polypropylene, polyvinyl chloride, polystyrene, polyethylene, polyurethane, bakelite, silicone, E as shown in FIG.
It is made of a sheet-like material made of PDM, pyroas, sheathing, asphalt felt, foamed rubber, various synthetic resins, plastic bodies, and the like.

The shape of the waterproof sheet B is a vertical laying piece 4,
It is formed of an elongated body formed with a plurality of projecting rain return pieces 5 projecting so as to be inclined vertically or downward from the surface of the laying piece 4, and at least the rain return pieces 5 are soft and elastic. Have

The laying piece 4 is interposed between the fixed piece 1 of the draining material A and the dry wall material C. The laying piece 4 is bonded to the draining material A via various adhesives or by heat fusion, and is integrally formed. Or fixed directly to the base material α using a fixing tool β such as a nail. As shown in FIG. 1, the rain return pieces 5 are in close contact with the back surface of the drywall material C to achieve a waterproof effect of multiple layers, completely shut out rainwater and the like into the inside of the base, and improve the waterproofness. This is for preventing corrosion of the base material α.

Further, by forming the laying pieces 4 of the waterproof sheet B from a hard material and the rain return pieces 5 from a soft material, the adhesion to the back surface of the dry wall material C is further enhanced, and a large number of pieces are formed. It is also possible to form voids to prevent capillary action and improve waterproofness.

Examples of the dry wall material C include, for example, a sandwich panel such as a metal siding material or a metal panel as shown in FIGS. 13 (a) to 13 (g), and FIGS.
It is a long plate such as a ceramic siding material, a ceramic plate, a tile plate and the like as shown in FIG.

The base material α is a steel base such as an H-shaped steel, a square steel, a C-shaped steel, or a wooden base such as a main pillar, a stud and a rim of a body. It is provided with a sheet and the like.

Next, a construction example will be described. Now, a drainer A as shown in FIG. 2 and a waterproof sheet B as shown in FIG.
It is assumed that a joint as shown in FIG. The waterproof sheet B was previously fixed on the fixing piece 1 of the draining material A via an adhesive and integrated. Therefore, first after application of drywall material C ₂ in the lower part, the base material α and the fixed piece 1 of draining material A waterproof sheet B is fixed by the fixture β such as a nail. Then in which upper rear surface of the drywall material C ₁ is laid so as to be in close contact with rain Kaehen 5, to form the joints.

What has been described above is only one embodiment of the exterior waterproof structure according to the present invention. The base structure shown in FIG. 4 and the upper opening (upper window) shown in FIG. 5 can also be used. In addition, in FIG. 4, D is a foundation, E is a base, and F is an upper sash in FIG. Also, FIG. 6 is a laid structure so as to cover the fixing piece 1 of draining material A waterproof sheet B, a waterproof sheet in between 7 reinforcement portion 3a and the lower drywall material C ₂ for draining material A B has a structure in which waterproofness is improved by interposing B.
