Abstract

(57) [Summary] (Modified) [Purpose] Use circular columns or cylindrical columns instead of conventional spherical fine grains such as glass or plastic to form the reflective surface of concrete structures. This is an attempt to change from the reflective expression to the reflective expression of lines. [Structure] A part of the circumferential surface of the circular column 1 made of transparent glass or plastic is exposed in parallel on the surface portion of the concrete structure 2, and the remaining circumferential surface is enclosed within the surface portion. Before the concrete is cast, a parallel light beam 3 is irradiated beforehand on the circumferential surface of the wrapping portion to be fixed, and a focal line 4 is formed outside the outer circumference of the wrapping portion. Is connected to the inner bottom surface of the dish-shaped reflection lid 5 having a band-shaped and a dish-shaped cross section, and further, the dish-shaped reflection is provided so as to secure a gap space 6 between the circumferential surface of the holding portion and the dish-shaped reflection lid 5. It is configured such that concrete is placed after the compatibility edge of the lid 5 is adhered to the circumferential surface of the wrapping portion.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a reflective surface structure in which a reflective surface portion of a concrete structure or the like is formed by using a circular column such as glass or plastic.

[0002]

[Prior art]

 Conventionally known as a method of forming a reflective surface portion of a concrete structure or the like is the application of the same applicant, in 1985, Japanese Patent Application No. 280414 (Japanese Patent Publication No. 4-142228), entitled “Reflected Light Surface”. There is a method of forming by using spherical fine particles such as glass or plastic in "Placing method of concrete structure having".

[0003]

[Problems to be solved by the device]

 However, in the conventional method of using spherical fine particles such as glass or plastic of the same applicant, for example, when a character or a figure is reflected on the surface of a concrete structure, a large amount of amount, labor and cost are required. There was a drawback that required.

[0004]

[Means for Solving the Problems]

 Therefore, the present invention replaces the conventional reflective expression with spherical fine particles such as glass or plastic, and uses a circular column such as glass or plastic whether it is straight or curved with a certain length. Then, the reflection expression of points is changed to the reflection expression of lines.

Next, the present invention will be described in detail with reference to the drawings. FIGS. 1 and 2 are a front view and a plan view of a main body structure of the present invention, and FIGS. FIG. 5 is a side view and a plan view showing a partial cross section, and FIG. 5 is an explanatory view in which FIG. 4 is enlarged.

As shown in FIG. 3 and FIG. 4, a circular column 1 having a circular cross section made of transparent glass or plastic exposes a part of the circumferential surface in parallel on the surface portion of the concrete structure 2 and leaves the remaining portion. Before the concrete is placed, the parallel light that crosses the exposed surface at a right angle in advance is embedded in the inner surface of the surrounding surface of the holding part, which is fixed by enclosing the circumferential surface in the same surface part. The wrapping part for the dish-shaped reflecting lid 5 which is irradiated with the line 3 and is connected to the inner bottom surface having a strip-shaped dish-shaped cross section, has a focal line 4 which is linearly connected to the outer circumference of the circumferential surface on the opposite side. The plate is provided parallel to the circumferential surface, and the plate-shaped reflective lid 5 is provided with a gap between the circumferential surface and the dish-shaped reflective lid 5, so that the side edge of the dish-shaped reflective lid 5 can be increased. After adhering to the peripheral surface (of course, the upper and lower ends of the dish-shaped reflective lid 5 are also closed), place concrete and After hardening, the above-mentioned exposed peripheral surface on the surface of the concrete structure 2 is irradiated with the light beam 3 and refracts through the inside of the circular column 1 and the gap space 6 to form a linear focus line 4 which is dish-shaped. The reflecting surface of a concrete structure or the like, which is tied on the inner bottom surface of the reflecting lid 5 and has a high-reflecting reflecting function on the inner bottom surface, is made of glass, plastic, or the like. It is a reflecting surface structure formed by using a circular column.

[0007]

[Action and effect]

 In the structure of the present invention constructed as described above, since the surrounding structure of the gap space 6 completely prevents the infiltration of the solution or the like when pouring concrete, the focus line is always on the inner bottom surface of the dish-shaped reflection lid 5. 4 can be tied.

Further, in the structure of the present invention, as shown in the enlarged explanatory view of FIG. 5, the ray of the ray 3 at the arrow A portion is efficiently reflected at the arrow A ′ portion, and the ray at the arrow B portion is efficiently reflected at the arrow B ′ portion. Therefore, the glitter condensed on the focal line 4 can be spread over the entire circumferential surface of the exposed portion to form an effective reflection surface portion of the glitter concrete structure 2.

The structure of the present invention can be widely applied not only to the formation of the reflective surface portion of the concrete structure 2 but also to the formation of the reflective surface portion of other structures.

【Example】

 Further, the present invention adopts a hollow cylindrical column 7 instead of the circular column 1 as shown in the front view and the plan view of FIG. 6 to fill the inside with an appropriately colored liquid 8. It is also possible to freely change the color of the reflected ray by exchanging.
