1 to 2, the retroreflective block 100 for a pedestrian road disclosed in the present specification may include a retroreflective module 110 and a block body 120. Since the illustrated components are not essential, a retroreflective block for pedestrian roads having more components or fewer components may be implemented.

The block body 120 may further include a concave portion 122 formed by being recessed from the upper surface 121 in the inner direction of the block body 120.

A module inlet 123 for fixing the retroreflective module 110 may be formed in a portion of the concave portion 122.

The retroreflective module 110 may include a module fixing part 111 and a retroreflective plate 112. The module fixing part 111 is formed to protrude from the bottom of the retroreflective module 110, and the retroreflective plate 112 is coupled to and fixed to the coupling part 113 formed on one surface of the retroreflective module 110. At least one retroreflective plate coupling protrusion 1121 may be formed in a portion of the retroreflective plate 112 so as to be inserted into the coupling part 113 and not separate.

The module fixing part 111 may be inserted into the module inner part 123 to fix the retroreflective module 110. The module fixing part 111 includes a coupling protrusion 1111 formed on a side surface, and the coupling protrusion 1111 is the coupling protrusion when the module fixing part 111 is inserted into the module inner inlet 123 Separation of the module fixing part 111 can be prevented by locking the 1111 to the inner surface of the module inner inlet 123.

The bottom surface 1221 of the concave portion 122 has a certain inclination in the direction of the module inner inlet 123 at a point 1222 of the upper surface 121 and is depressed to form the concave portion 122 do. The constant inclination is preferably within -10 degrees based on the upper surface 121, but in consideration of the size of the block body 120 and the retroreflective plate 112 or/and the visibility of the driving vehicle It can be changed to various angles.

The retroreflective block 100 is combined with the retroreflective module 110 so that when the driver of the vehicle is driving, the upper surface 121 of the block is recessed so that the retroreflective plate 112 is clearly visible, and the concave portion 122 And the dent shape may form a module inner inlet 123 at a portion that flows to the surface starting at an angle of about -10 degrees from the side and ends at an angle of about -10 degrees. The retroreflective module 110 is coupled to the module inner inlet 123 formed as described above, and has a shape of a block body 120 in which the retroreflective plate 112 can be seen without difficulty in the driving direction of the driver.

Meanwhile, the retroreflective module 110 excluding the retroreflective plate 112 may be made of a material resistant to impact and heat by using a die casting casting technique.

In addition, in the case of the retroreflective plate 112, since the conventional sheet-shaped reflector is susceptible to contamination and wears well, it can be made of transparent polycarbonate, and the rear surface of the retroreflective plate 112 (the surface attached to the coupling part 113) ) Can be produced by post-processing with high luminance retroreflective spray. The high luminance retroreflective spray is mixed with fine glassbeads, and when it is coupled to the coupling part 113, it is located on the back side of the retroreflective plate 112, so it has a semi-permanent characteristic.

In addition, the rear surface of the retroreflective plate 112 must have a three-dimensional protruding pattern (Fig. 7(c)), and the protruding pattern is a stepped staggered pattern (Fig. 7(b)) or a diagonal repeating pattern (Fig. Since it is 7(a)), it has a characteristic of causing retroreflection according to the driver's gaze direction. Since the surface on which light is reflected from the three-dimensionally protruding pattern on the back of the retroreflective plate 112 is formed at a right angle to the horizontal floor of the road surface, the reflective surface on the back of the reflector when the vehicle light illuminates the roadway and/or sidewalk It is level with the light, so retroreflection can occur. In addition, some diffusely reflected light is secured in the pedestrian's field of view by the three-dimensional protruding pattern on the back, so that the pedestrian can safely distinguish the lane from the pedestrian path.

Since the reflective surface of the retroreflective plate 112 is installed to have an angle of 5˚ to 90˚ from the vertical of the upper surface 121 of the block body 120, rainwater and contaminants flow down by gravity in rainy weather. I can go.

In addition, the block body 120 may be formed including a surface layer 125 and a base layer 126.

The surface layer 125 preferably has a thickness of 6mm to 8mm, and is formed by mixing and drying silica sand, white portland cement, solid, melanomatite, copper slag, and liquid pigment, and the silica sand, the melanomatite and The particle size of the copper slag may have a particle size of 1mm to 4mm.

Meanwhile, the module inner inlet 123 may be formed on the surface layer 125 and may be formed within the thickness of the surface layer 125. Accordingly, even if the retroreflective module 110 is inserted into the module inner fitting 123, the retroreflective module 110 may be coupled without shifting, and may be firmly coupled to the module inner fitting 123. If the size of the melanomax is larger than the size of the above-described particles, the shape of the coupling portion is not smooth due to the material characteristics of the retroreflective module 110, and the coupling force decreases, so that the retroreflective module 110 is configured with the block body ( 120) can be easily separated.

The base layer 126 may constitute the rest of the block body 120 except for the surface layer. In addition, the base layer 126 can be divided into two types depending on the function, and it has superior strength than the water-permeable base layer (not shown) and the water-permeable base layer (not shown), which allows water to fall easily in rainy weather. It can be classified as an impermeable base layer that does not break.

The main material of the water-permeable base layer is crushed stone aggregate, and the size of the particles is 3mm to 8mm, and due to the size, voids are formed in the base layer during the manufacturing process of the block, and rainwater flows down to the floor in rain due to the formed voids. You will be able to. The water-permeable base layer is formed by mixing crushed stone aggregate, a water-soluble admixture, blast furnace slag cement, and water. The water permeable base layer may be formed under the concave portion 122 or may be formed as a single layer over the entire base layer. Therefore, even if rainwater accumulates in the concave portion 122, the water falls through the water-permeable base layer, so that the reflective performance of the retroreflective plate 112 is not deteriorated.

The impermeable base layer may be formed by mixing stone powder, crushed stone aggregate, blast furnace slag cement, admixture, and water. The impermeable base layer can minimize the breakage of the block even when the vehicle is raised above the block. The impermeable base layer may be formed surrounding the water permeable base layer, or may be formed as a separate layer under the water permeable base layer.

That is, the first concave portion 222-1 of the retroreflective block 200 for sidewalks and the second concave portion 222-2 ′ of the adjacent retroreflective block 200 ′ for sidewalks are substantially connected to one another. It is possible to form a concave portion. In this case, since rainwater flows through the gap between the side surfaces where the retroreflective block 200 for sidewalks and the retroreflective block 200' for sidewalks abut, rainwater cannot accumulate in the concave portion. Accordingly, in the retroreflective block for a sidewalk according to an exemplary embodiment of the present invention, rainwater accumulates in the concave portion, so that the reflection performance of the retroreflective plate does not deteriorate.
