Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nail which is coated on the top surface of a stainless steel nail to improve the harmony with the periphery of the top surface exposed on the construction surface when used for fastening a building material or the like. About.

[0002]

2. Description of the Related Art Nail used for fastening building materials was made of iron in old times, but in recent years, there has been no problem of rusting, and stainless steel nails having durability sufficient for the service life of buildings and the like have been developed. It is heavily used.

[0003] However, when the building material is fastened with stainless steel nails, the top surface of the stainless steel nail exposed on the construction surface has a silver-white color even after time due to its excellent corrosion resistance. In addition, since it looks as if it shines by reflecting light, it is very conspicuous even though the exposed area of the top surface itself is small. In particular, in the case of dark-colored building materials, there is a tendency to be seen as a cheap contract because the sense of discomfort with the surroundings is large, the aesthetic appearance is significantly impaired, and the metallic top surface is exposed.

[0004] For this reason, in the interior construction work of a house, in general, after nailing a base board with a nail, a wallpaper or a decorative board is stuck with an adhesive on the board. Is not used.

However, both the application of the wallpaper to the base board and the application of the decorative board require a skilled worker and require a curing period, so that the construction period is long, and the base board is nailed. If the wallpaper is pasted after fixing, the number of man-hours increases, which is not preferable in terms of cost. Moreover, the use of the adhesive has a problem that the working environment is deteriorated due to evaporation of the solvent. Further, there is a problem that the replacement is not easy.

On the other hand, the dry method of nailing a decorative panel can be performed relatively easily without the need for skilled skills, does not require a curing period, and deteriorates the working environment. Even without the problem described above, the work can be easily performed in a short period of time, and can be easily removed at the time of remodeling after the work.

However, as described above, the construction of building materials by nailing is not generally employed in interior construction work because of the discomfort of the top surface of the nails exposed on the construction surface.
In addition, in the exterior construction, it is currently employed after neglected inferior appearance and luxury.

[0008]

SUMMARY OF THE INVENTION Accordingly, the present invention solves such a problem of the stainless steel nail, and when used for fastening a building material or the like, the top surface exposed on the construction surface is in good harmony with the surroundings. It is an object of the present invention to provide a nail which can provide a construction surface excellent in aesthetic appearance and luxury.

[0009]

The nail according to the present invention is characterized in that the top surface of a stainless steel nail is blasted and then the top surface is painted.

With the nail of the present invention, by applying a coating in harmony with the surrounding color tone on the top surface, the top surface exposed on the construction surface is inconspicuous and forms a construction surface excellent in aesthetic appearance and luxury. be able to.

[0011] Incidentally, stainless steel nails generally provided include those having lattice-like irregularities formed on the top of the head,
Some have a smooth top surface. In the case of simply painting the top of the nail with a smooth top,
When the crown surface is hit with a hammer during construction, the paint adhering to the crown surface easily peels off. On the other hand, even if a nail with a grid-like irregularity formed on the top of the nail is simply painted on the top of the nail, the hammering of the top of the nail with a hammer will leave the paint in the recess on the top of the nail, but will stick to the convex. The paint is peeled off, so the presence of nails is also noticeable.

On the other hand, in the present invention, since the top surface is blasted and roughened to apply the coating, the paint adheres firmly to the blasted surface, and even if the top surface is hit with a hammer during construction. The paint does not come off.

In the present invention, more specifically, the nail head is subjected to sand blasting, degreasing, and then painting.

This coating may be applied in two or more layers. In this case, the first layer is uniformly applied to the top of the head, and the second and subsequent layers are applied in the form of spots, thereby giving a natural stone-like design. You can get high nails. Also, after coating, the painted surface may be blasted to give a matte appearance.

[0015]

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the nail of the present invention, and FIG. 2 is a sectional view of a parietal portion showing an example of a procedure for manufacturing the nail of the present invention.

The nail 1 has a natural stone-like coating 4 applied to the top surface 3 of a stainless steel nail 2.

As shown in FIG. 2, the nail 1 is made by roughening the smooth surface (FIG. 2A) of the crown 3 of the stainless steel nail 2 by sandblasting or the like (FIG. 2B). 3A is a roughened surface.) Then, preferably after a degreasing treatment, the paint 5 is uniformly applied as a first layer, and then a second layer is formed.
As a layer, it can be produced by applying a paint 6 having a color tone different from that of the paint 5 in a spot-like manner.

The blast treatment is very important for increasing the adhesion strength of the paint to the top surface. In general, sand blast treatment is employed, but the degree of surface roughening is determined by the surface roughness and the average standard roughness. It is preferable that the thickness Ra be about 1.5 to 3 μm in order to obtain high adhesion due to the anchoring effect of the paint, to prevent peeling during construction, and further to prevent peeling after construction.

Such a degreasing treatment of the blasted surface can be performed according to a conventional method.

In the present invention, the paint used for coating is not particularly limited, and various paints such as a thermosetting type and an ultraviolet curable type can be used. Although there is no particular limitation on the type of resin, in general, acrylic resin, fluororesin,
Epoxy resin and the like are suitable. In particular, fluororesin-based coatings have high weather resistance and are not easily discolored and discolored, and therefore are suitable for exterior construction.

There is no particular limitation on the method of applying the paint. However, in the case of a uniform paint surface, the nail surface is dipped in the paint and the side surface of the nail surface is also painted in the case of the deep pink method. This is preferable. In the case of applying a spot-like coating, a spray method or the like is suitable.

If the thickness of the coating film to be formed is too thin, it tends to peel off when struck with a hammer at the time of construction, and it is uneconomical even if it is excessively thick. preferable.

The decorative surface of the crown surface by painting is appropriately determined according to the purpose of use of the nail, the color tone and texture around the construction object, for example, the surface pattern of the building material to be fastened, and for example, the following decoration can be applied. it can. The top blasted surface is further painted to a single color. As shown in FIG. 1, two layers of coating are applied to the blast-treated surface of the top of the head, and the lower layer is uniformly made into a speckled upper layer to give a natural stone-like texture. In this case, a spot-like coating may be further applied. Alternatively, a blast treatment is further applied to the painted surface to obtain a matte surface. Alternatively, a transparent coating is further applied to the painted surface to provide a glazed surface.

Such a nail of the present invention is industrially extremely useful for dry-type construction by nailing of interior and exterior materials.
In particular, in the interior construction, it is possible to easily form a good-looking construction surface in a short period of time by directly nailing the decorative board without necessitating sticking of wallpaper or the like as in the related art.

The nail of the present invention is suitable not only for the construction of construction materials but also for the manufacture of furniture and fittings, and can easily produce beautiful and high-quality furniture and fittings without post-processing of the nailing surface. can do.

[0027]

As described in detail above, when the nail of the present invention is used for fastening a building material or the like, the top surface exposed on the construction surface is inconspicuous and is in harmony with the surroundings.
It is possible to form a construction surface that is excellent in aesthetics and luxuriousness by dry construction by nailing, which is easy to carry out and is advantageous in terms of working environment.
