Description

[Detailed Description of the Invention] A method known to reveal the shape and location of concrete structures by receiving external light at night or in dark places such as tunnels and basements uses spherical glass powder added to the paint. There are methods such as painting with a luminous paint containing added or kneading spherical glass powder into a part of the aggregate of concrete structures.

However, the former method has the disadvantage that the paint film peels off and falls off due to human friction and natural phenomena such as severe wind, rain, snow, and temperature differences, requiring repeated repainting, and the latter method uses relatively cheap spherical glass powder to make concrete. Disadvantages include the need to use large amounts of glass powder as part of the aggregate, and the extreme difficulty of placing spherical glass powder on the desired concrete surface, and even if some remains near the concrete surface. The drawback was that most of its reflective function was taken away by the adhesion of fine concrete solution.

Therefore, the present invention eliminates these drawbacks and makes it possible to arrange a large number of fine spherical particles made of glass or plastic, which allow light to pass through freely, on the surface of a concrete structure where a reflective light surface is desired. A large number of fine spherical particles of glass or plastic are applied to the surface of the frame board in the same way as regular glue or paper work, and placed and glued as appropriate before the glue part dries, and then reflected from above after the glue part dries. The remaining spherical part other than the glued spherical part and the glue part other than the glued spherical part are coated with a reflectance coating, and after concrete is poured, only this remaining coated spherical part is enclosed within the concrete surface part. In addition, the gluing spherical part is coated with the above-mentioned series of paints so that the inner spherical surface emits reflected light with a high reflectance. After curing, the form board and glue parts are removed to create a spherical part that is exposed on the concrete surface and allows light to freely pass through.

Next, the present invention will be explained in detail with reference to the drawings.
As shown in the front view of the figure and the sectional view of Figure 2, there are many moisture supply holes 4' drilled in the plate surface to facilitate moisture supply between the concrete surface and the form frame plate surface, which has been known in the past. A glue part 2 for gluing is applied directly or through a mount 1 etc. to the board surface of the frame board 4 having a shape plate 4, and the light beam is freely passed through the glass or plastic before the glue part 2 dries. A large number of spherical fine particles 3 are arranged in a planar shape (meaning that a large number of particles are arranged to form a surface), letters, figures, etc. and glued, and after the glued part 2 dries, a reflectance coating is applied on top of it. As shown in the detailed view of FIG. 3, a reflective paint film 3' covers them.

With the form plate 4 constructed in this manner, concrete 5 is poured as shown in the cross-sectional view of FIG. 4 by aligning the reflective light surface of the concrete structure with the desired surface area, and after the concrete 5 has hardened, moisture supply holes are placed. 4' to dissolve and remove the mount 1, glue 2, etc. together with the form frame plate 4, the spherical thin material of glass or plastic can be formed as shown in the cross-sectional view of FIG. 5 and the detailed view of FIG. 6. Each of the grains 3 is pasted by the glue part 2, and is exposed on the surface of the concrete 5 by dissolving and removing the glue part 2, and has a spherical part that allows light to pass through freely, and a remaining reflectance. The inner spherical surface of the concrete 5, which is coated and covered with a reflective paint film 3', forms a spherical part that emits reflected light rays, and the action of both component spherical parts. As a result, a large number of spherical fine particles 3 of glass, plastic, etc. arranged in the above-mentioned manner, such as plane shapes, characters, figures, etc., form a reflective light surface of the concrete structure that receives external light and emits reflected light with a reflectance. This is a method of placing concrete structures with reflective light surfaces.

In this way, the method of the present invention is semi-permanent, unlike the conventional luminous paint coating in which spherical glass powder is simply added to the paint. Unlike those that require a large amount of kneading, it is extremely superficial and economical, and is far superior in terms of structural strength.

If this method of the present invention is applied to buildings,
As long as various light rays continue to intersect in the night sky of a city, buildings that receive them can continue to clarify their beauty of form and location. If applied to safety signs such as bridge railings, pedestrian and roadway curbs, road markings, telephone poles, etc., it will be a semi-permanent and comfortable transportation solution, unlike the current blind coating of luminescent paint, which is extremely inferior in aesthetic sense. Safety can be ensured.

Here, although the spherical fine particles 3 are described in this specification, if the spherical surface is appropriately cut or the like, the reflected light beam can be given directionality. In addition, although this specification describes things that can be dissolved and removed by applying moisture, such as the mount 1 and the glue part 2, a glue agent that can be melted and removed by heating the metal form board is used and heated after concrete is placed. The same purpose can be achieved even if you try to manage it. In addition, even if some of the spherical fine particles 3 in which the spherical fine particles 3 are arranged in a planar manner and some of the painted film 3' are of a different color, characters, figures, etc. can be produced. Furthermore, although concrete structures are described in this specification, the method of the present invention can also be applied to thin or small structures made only of lightweight concrete, mortar, or cement.

Note that FIGS. 7 and 8 are examples in which linear waveforms and curved waveforms are adopted for the mounts 6 and 8, respectively, and are similar examples in which a sudden change or a gradual change in reflected light rays is achieved by moving an external light source.
