2. Description of the Related Art Conventionally, there are guide signs and guide signs provided on road shoulders as ancillary facilities of roads intended for safe driving of automobiles. For example, the guidepost is provided with a guard rail a made of a metal plate along the roadway S as shown in FIG. 9, and a frame b for mounting is provided on the upper surface of the guard rail a at desired intervals. Is provided with a reflector K '. In addition, as shown in Fig. 11, there is a concrete curb block c which is continuously laid on the boundary between the road S and the human road J, and a reflector K "is provided as a guide mark on the concrete curb block c. K ″ has a structure in which a colored synthetic resin plate e having a large number of uneven surfaces d is superposed and mounted on the front surface of a mirror plate f as shown in FIG. 10 or FIG. When the light is applied to the reflection plates K 'and K ", the light is transmitted through the synthetic resin plate e, and a difference in reflectance occurs due to the uneven surface d. In addition, as another conventional example, a guide mark is formed by applying a reflective paint or a fluorescent paint to an object to be adhered. High retroreflective properties as a component material that can be used effectively in the future There are Russ bead. Then to mount the glass beads adherend body, for example, FIG. 13
As shown in (1), a method of attaching the glass beads h to the adherend i using the adhesive g 'can be considered. On this occasion,
In order to form an adhesive layer g for bonding the glass beads h to the adherend i, the adhesive g 'is applied to the adherend i using an applicator such as a brush. Was.

[0003]

As shown in FIG. 9, a reflector K 'which is provided at a desired distance using a frame member b on a top surface of a guard rail a as shown in FIG. 9 or a curb block c as shown in FIG. Is formed by polymerizing a synthetic resin plate e having a large number of uneven surfaces d on the front surface of a mirror surface plate f as shown in FIG. 10 or 12, and is manufactured and assembled in a factory. Further, at the construction site, the reflector K 'is attached to the guard rail a using the frame material b.The curb block c shown in FIG. When forming the curb block c, the reflector K ″ is attached to the curb block c.
The reflector K "is attached to the curb block c by embedding it in the wall, or the reflector K" is adhered to the curb block c using an adhesive, and further, the reflector K is attached to the curb block c at a factory by screwing or the like. ″ Was installed. As described above, the production and assembly of the reflectors K ', K ", and the reflection of the reflectors K', K" to the adhered object i such as a metal structure or a concrete structure.
It took a lot of time and effort to attach the K ″.
In addition, a special frame member b is required as an attachment part for attaching the reflector K 'to the adherend i consisting of the guard rail a, so that the attachment requires a lot of time and labor. The number of parts increased and the production cost increased. In addition, as shown in FIG. 13, a glass bead h is attached to an adherend i via an adhesive layer g 'as a component material having a high retroreflective property. Since the adhesive layer g was formed by applying the agent g 'to the adherend i, the operation of applying the adhesive g' required much time and labor, resulting in poor workability. In addition, since the adhesive g 'is applied by a brush, the thickness t' of the adhesive layer g formed on the adherend i is not constant, and the thickness of the adhesive layer g varies. For this reason, the mounting surface of the adhesive layer g with respect to the glass beads h does not become a flat surface, and a level difference is generated and the surface is not uniform.
The reflecting surface of the beads h is not uniform. For this reason, when the light I is irradiated to the glass beads h, the intensity of the reflected light I 'appears and irregular reflection easily occurs, the regression reflectivity is reduced, and the visibility is impaired. Moreover, glass beads h
In order to manufacture a reflector made of
In this state, the glass beads h are scattered by dropping the glass beads h from above onto the adhesive layer g formed by applying the adhesive g 'using a brush, and the glass beads h are attached to the adhesive layer g. The degree of contact of the glass beads h with g was not constant, and the glass beads h were not fixed to the adhesive layer h with a sufficient degree of embedding. Therefore, since the glass beads h are easily peeled off from the adhesive layer g and the structure is fragile, the reflection parts using the glass beads have not been practically available.

[0004] Therefore, the present invention provides a method for applying a desired thickness to an existing concrete structure such as a curb block, a protective wall or the like, a metal structure such as a guard rail, or an object to be adhered such as a wooden structure at a construction site. The adhesive layer is easily and reliably obtained to improve workability, and the thickness of the adhesive layer is constant and the mounting surface is formed on a uniform flat surface without variation, so that the spherical reflector is quickly and peeled off from the adhesive layer. It is hard to be mounted, has a strong structure, and has excellent visibility without impairing the retroreflective property. Further, the number of parts is small, and the production cost and the construction cost are reduced.

【The invention's effect】

one. As described above, the present invention can be applied to existing concrete structures such as curb blocks, protective walls and the like, metal structures such as guard rails, and even objects to be adhered such as wooden structures to a desired thickness at a construction site. Since the adhesive layer and the spherical reflector can be easily and reliably obtained by spraying, the workability is greatly improved. two. Further, according to the present invention, since the adhesive layer is formed by spraying the existing adherend at the construction site, the adhesive layer can be formed to have a constant thickness and a uniform flat surface with no variation in the mounting surface.
For this reason, visibility is improved without impairing the recursive reflectivity of glass beads or resin beads serving as spherical reflectors attached to the adhesive layer. The thickness of the adhesive layer can be easily adjusted according to the particle size of the spherical reflector. three. The present invention also provides a uniform and flat mounting of an adhesive layer formed on an adherend by spraying a spherical reflective material having a desired particle diameter having a desired particle diameter and having a desired particle diameter and a recursive reflectivity by discharging pressure from a nozzle. Since the rear surface is mounted on the surface so that the rear surface is embedded, the spherical reflecting material can be securely mounted on the object without peeling off to form the reflecting layer.
