Description

  The present invention relates to a side groove lid made of colored concrete.

  Conventionally, U-shaped side grooves made of concrete are mainly laid on the road side end for guiding rainwater, irrigation water, drainage water, etc., and rectangular flat concrete side groove covers are used for the upper surface openings. A plurality of the side groove lids are placed adjacent to each other in the longitudinal direction of the upper surface opening of the U-shaped side groove. In recent years, from the viewpoint of traffic safety, for drivers and pedestrians traveling on the road at night, especially at night, it is (1) near the road side edge, (2) near the doorway, (3) near the corner, etc. In order to clearly indicate the warning, the road surface or the side groove cover surface is partially colored with paint or the like.

  In general, coloring and painting a surface of a concrete block or the like is not easy because long-term maintenance management is required because repainting is necessary because the paint deteriorates due to wind and rain, ultraviolet rays, etc. and partially peels off. In view of this, Japanese Patent Publication No. 61-36423 (Patent Document 1) proposes a colored concrete block obtained by adding a colorant to a concrete raw material.

This colored concrete block is colored with grass, earth, yellow, etc., as appropriate, in order to harmonize with the natural environment and clearly warn you of parking prohibited areas. Problems such as deterioration and delamination are resolved. Furthermore, when using a single color concrete block that is appropriately colored on the sidewalk boundary, a warning is given by clearly indicating the boundary position to the driver and pedestrian by placing different colored concrete blocks alternately (see Patent Document 1 and FIG. 2). It is said that there is an effect to do.
Sho 61-36423

  There is a problem of partial deterioration of the paint by appropriately coloring the surface as in the prior art.To solve this, simply placing the colored block in the longitudinal direction as described above, the driver, There was a limit to the effect of warning the pedestrian by indicating the boundary position. In the present invention, in a conventional U-shaped side groove, a rectangular flat plate-shaped side groove lid is continuously placed adjacent to the longitudinal direction of the upper surface opening so that a design attracting attention for drivers and pedestrians is obtained. It is an object to provide a concrete side groove lid that realizes and provides a warning effect by further clarification.

  In the present invention, means for solving the problems are as follows. That is, a rectangular rectangular flat side groove cover made of concrete, at least a portion near the rectangular surface is composed of a yellow colored concrete portion and a black colored concrete portion, and a boundary between the colored concrete portion appearing on the rectangular surface The side groove cover is characterized in that the line is inclined with respect to the side of the side groove cover.

  According to the present invention, on the rectangular surface of the side groove cover, the boundary line made of the concrete portion colored yellow and black is disposed to be inclined with respect to the side of the side groove cover. Therefore, by continuously placing the side groove cover of the present invention in the longitudinal direction of the U-shaped side groove opening so that the same color side is adjacent, the yellow / black part having an inclined boundary line on the surface of the side groove is strip-shaped. Therefore, it is possible to realize a design that attracts attention to the driver and the pedestrian, and to provide a warning effect by further clarification. Furthermore, in the present invention, since the repeated pattern is formed of colored concrete, problems such as conventional partial degradation and peeling due to painting can be solved.

  An embodiment of the present invention will be described with reference to the drawings.

  (Embodiment 1) FIG. 1 is a perspective view of a colored concrete side groove cover 1 of the present invention. As shown in FIG. 1, the side groove cover 1 includes parallel sides (4a, 4b) and side surfaces ((5a, 5b), and side parallel sides (4c, 4d) and side surfaces (5c). As shown in Fig. 1, the side groove cover of the present invention is composed of a yellow concrete part 2a and a black concrete part 2b. The boundary line 3 appearing on the rectangular surface 2 is inclined with respect to the side edges (4a, 4b) of the side groove cover 1. This inclination angle can be arbitrarily set, and both ends of the boundary line 3 are parallel to both side edges (4a In the present embodiment, the inclination angle at the intersection A of the boundary line 3 and the side 4a is 45 degrees, so the inclination angle at the other point B is also 45 degrees.

  In the present invention, the rectangular surface 2 is the upper surface (upper surface) when the side groove lid 1 is placed in the U-shaped side groove. In FIG. 1, the handle 6 is provided on the side surface (5c, 5d) on the adjacent side when the gutter lid is placed, but this may be provided on one or both sides or not at all as required. good.

  The yellow and black colored concrete constituting the present invention is solidified by mixing a predetermined amount of aggregate, a coloring pigment and water with normal Portland cement before kneading and placing it in a mold. First, weirs are installed in advance to incline the boundary line with respect to both sides (4a, 4b) in contact with the bottom of the box-shaped formwork (the bottom surface becomes a rectangular surface after solidification of the concrete). To do. A yellow colored concrete obtained by adding a color pigment is placed in one of the mold space divided into two by the dam plate and solidified by placing it, and then the dam plate is removed. Next, black colored concrete is cast into the other surplus space in the mold and solidified. Since the weir plate is removed and cast, both colored concrete forms a clear boundary. A fine glass powder may be added to the colored concrete and scattered on the surface to diffusely reflect light and make the colored surface more noticeable.

(Embodiment 2) FIG. 2 shows the boundary line 3 as a diagonal line of the rectangular surface 2. The intersection A between the boundary line 3 and the side edge 4a and the intersection B between the boundary line 3 and the side edge 4b are located at two diagonal vertices of the rectangular surface.
(Embodiment 3) FIG. 3 shows a case where the yellow concrete portion 2a and the black concrete portion 2b are only the rectangular surface vicinity 2c of the side groove lid 1. FIG. The lower main body 7 other than the rectangular surface vicinity 2c is made of ordinary Portland cement concrete to which no color pigment is added.

  FIG. 4 is an explanatory diagram in which the colored concrete side groove cover 1 described in the first embodiment is actually applied to the U-shaped side groove 10. The U-shaped side groove 10 is placed so as to bridge the lid receiving portion surface 11 inside the lid receiving side wall 12. By continuously placing the side groove lid 1 of the present invention so that the colored portions of the same color are adjacent to each other in the longitudinal direction, a continuous repetitive pattern can be formed while the yellow and black portions exhibit an oblique boundary.

  FIG. 5 is a plan view showing a state in which the colored concrete side groove cover 1 of the present invention is placed in a U-shaped side groove. FIG. 5 (a) shows the first embodiment, and FIG. 5 (b) shows the case where the side groove cover of Example 2 is continuously placed. In the longitudinal direction of the side groove, the yellow and black portions are continuous with an oblique boundary. The repeated pattern is formed. The present invention can be easily applied to the existing U-shaped side groove because the shape of the side groove lid is a rectangular flat plate that has been frequently used in the past, and by continuously placing as described above, roads, parking lots, etc. In, a continuous pattern of yellow and black having an oblique boundary line that draws attention to the pedestrian and driver can be formed.

It is a perspective view which shows Example 1 of this invention. It is a perspective view which shows Example 2 of this invention. It is a perspective view which shows Example 3 of this invention. It is explanatory drawing which applies the side groove cover of this invention to a U-shaped side groove. It is a top view of the state which mounted the side groove cover of this invention in the U-shaped side groove.
