Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings so that those of ordinary skill in the art may easily implement the present application. However, the present application may be implemented in various different forms and is not limited to the embodiments described herein. In addition, in the drawings, parts irrelevant to the description are omitted in order to clearly describe the present application, and similar reference numerals are attached to similar parts throughout the specification.

Throughout the present specification, when a part is said to be "connected" with another part, it is not only the case that it is "directly connected", but also "electrically connected" or "indirectly connected" with another element interposed therebetween. "Including the case.

Throughout the present specification, when a member is positioned "on", "upper", "upper", "under", "lower", and "lower" of another member, this means that a member is located on another member. This includes not only the case where they are in contact but also the case where another member exists between the two members.

In the entire specification of the present application, when a certain part "includes" a certain component, it means that other components may be further included rather than excluding other components unless specifically stated to the contrary.

Hereinafter, a photoluminescent sidewalk block (hereinafter referred to as'the main sidewalk block') to which a photocatalyst is applied according to an embodiment of the present disclosure will be described.

1 is a cross-sectional view showing a schematic configuration of a photocatalyst surface-applied photoluminescent sidewalk block according to an embodiment of the present application.

Referring to FIG. 1, the sidewalk block 100 includes a body portion 1, a plurality of phosphorescent grains 2, and a cement paste portion 3.

The body portion 1 includes a base layer 11 and a surface layer 12 in the form of a porous media formed on the base layer and in which a plurality of pores are formed to have water permeability.

The plurality of pores may be formed to have interconnectivity between neighboring pores so that the surface layer 12 may have water permeability. In this way, a plurality of pores are formed to have water permeability (interconnectivity between pores), so that the cement paste to be described later through the interconnected pores also reaches the pores exposed on the surface of the surface layer 12 and then the pores located at the lower side. It can penetrate into the inside of the surface layer 12 in the form of a porous media in a form that is gradually moved. As will be described later in more detail, as the cement paste permeates and cures (hardens) the pores having water permeability (interconnectivity), the cement paste part 3 can be integrally combined (connected) with the surface layer 12. have.

In other words, when cement paste is poured on the surface layer 12, after the cement paste is formed inside at least some of the plurality of pores located at the top of the surface layer 12, the plurality of pores in which the cement paste is formed and have interconnectivity. Cement paste may be formed inside at least some of the plurality of voids. In this way, since the cement paste is formed inside at least some of the plurality of voids, the integrity of the cement paste portion 3 and the surface layer 12 may be further strengthened.

For example, the surface layer 12 may be formed to be 10 mm or less. In addition, the surface layer 12 may be integrally manufactured using a method similar to the existing commercial product, but is not limited thereto.

FIG. 2 is a schematic cross-sectional view for explaining a process of arranging a plurality of photoluminescent particles on a surface layer in manufacturing a photocatalytic surface-applied photoluminescent sidewalk block according to an embodiment of the present application, and FIG. 3 is an embodiment of the present application It is a schematic cross-sectional view for explaining a process of first fixing by pressing a plurality of photoluminescent particles so that a plurality of photoluminescent particles are partially inserted into the surface layer in the manufacture of a photocatalyst is applied on the surface of the photoluminescent sidewalk block according to FIG.

The photoluminescent grains 2 are partially inserted and disposed in the surface layer 12 so as to protrude onto the upper surface of the surface layer 12. The photoluminescent particles 2 included in the sidewalk block 100 absorb and store (phosphorescent) light emitted or irradiated from light sources such as streetlight lighting and the sun, and then receive irradiation from the light source such as the street light is turned off or the sun is sunset. In situations where it is not possible, it can emit stored (phosphorylated) light by itself. For example, the photoluminescent granules 2 may be provided in the form of a photoluminescent stone or a photoluminescent capsule, which will be described later.

Referring to FIG. 2, the photoluminescent grains 2 may be once disposed on the surface layer 12 in a state that is not inserted into the surface layer 12. In this case, the plurality of photoluminescent grains 2 may be disposed on the surface layer 12 before the surface layer 12 is cured. Here, the term “before curing” means a state in which the surface layer 12 has not been cured (uncured state) to the extent that it can be partially inserted into the surface layer 12 when the plurality of photoluminescent particles 2 are pressed downward. I can.

Exemplarily, as a method of disposing a plurality of photoluminescent particles 2 on the surface layer 12, a method of randomly scattering a plurality of photoluminescent particles 2 on the surface layer 12, and on the surface layer 12 As another method of arranging a plurality of photoluminescent particles 2, a method of arranging the photoluminescent particles 2 on the surface layer 12 by using an automated machine in the designed design, and a plurality of photoluminescent particles on the surface layer 12 ( 2) As another method of arranging, there is a method of printing a pattern to be displayed on an adhesive coated paper and then covering it over the surface layer 12 and pressing the pattern so that the pattern is transferred to the surface portion of the surface layer 12, but is limited thereto. It is not.

As another example, as another method of arranging the plurality of photoluminescent particles 2 on the surface layer 12, there is a method of making a hole in a predetermined frame and allowing the plurality of photoluminescent particles 2 contained in the frame to pass through the hole. Here, the predetermined frame may mean a configuration including a plate in which a plurality of holes through which photoluminescent grains can pass are formed corresponding to a predetermined pattern, shape, and the like. For example, a plurality of holes may be formed at intervals along an outline line such as a pattern or shape. For example, the frame may be provided in the form of a box having a flat bottom surface as the plate material and an open top, but is not limited thereto. In this way, by injecting the photoluminescent particles into the upper side of the frame in which the plurality of holes corresponding to the pattern, shape, etc. are formed, the plurality of photoluminescent particles 2 pass through the holes formed in response to the previously planned pattern, shape, etc. Can be placed on

Referring to FIG. 3, a plurality of photoluminescent grains 2 disposed on the surface layer 12 are pressed downward by a press device having a flat lower surface, so that a portion of the surface layer 12 has the same protruding height within an error range. It can be inserted and first fixed.

Exemplarily, various pressing devices used in manufacturing a press block may be applied to the press device. In addition, in order to force the photoluminescent grains 2 to have the same protruding height within an error range, the press device is preferably a device having a flat lower surface. In addition, as described above, the surface layer 12 may be in a state of uncured to a degree that permits insertion of the photoluminescent particles 2 when the photoluminescent particles 2 are pressed by a press device. Accordingly, the photoluminescent grains 2 partially inserted into the uncured surface layer 12 may be first fixed by frictional force interacting with the inserted portion in a state in which the uncured surface layer 12 is in contact. For reference, having the same protrusion height within the error range means that the protrusion height is substantially the same, and it is not exactly the same protrusion height, but there is a slight difference but can be regarded as the same. It can mean having a protrusion height where only a level of error exists.

In addition, a method of pressing the plurality of photoluminescent particles 2 downward using a press device may include applying light vibration. As the pressure and vibration are performed in parallel, insertion of the photoluminescent grains 2 into the surface layer 12 in which curing is in progress can be made more efficiently.

FIG. 4 is for explaining a process of secondary fixing around the circumference of photoluminescent grains by pouring cement paste on the surface layer to form a cement paste part in the manufacture of a photoluminescent sidewalk block to which a photocatalyst is applied to the surface according to an embodiment of the present application. It is a schematic cross-sectional view.

The cement paste part 3 is formed of a material including cement and a photocatalyst. The cement paste part 3 may contain cement in the form of a cement paste.

For example, a shrinkage reducing agent and an expanding material may be mixed in the cement paste included in the cement paste part 3 to prevent cracking due to shrinkage. In addition, a high-performance water reducing agent, a thickening agent, and an antifoaming agent may be used in the cement paste in order to maintain an appropriate fluidity and viscosity. In addition, the cement paste may contain a liquid or powder quick-setting agent to shorten the curing time. In addition, calcium or a calcium compound may be additionally added to the cement paste to increase photoactivation and reduce NOx. In addition, the cement paste may include an inorganic color pigment in order to maximize the aesthetic function and increase the function of the phosphorescent stone.

In addition, the cement included in the cement paste may be ordinary portland cement (OPC), but is not limited thereto. As another example, high-powder cement may be applied to the cement included in the cement paste as a method for evenly filling the voids in the surface layer.

In addition, the photocatalyst included in the cement paste part 3 may include various photocatalysts that are known or developed in the future, which are used in the form of mixing (blending) with cement.

Referring to the enlarged view of FIG. 1 and FIG. 4, the cement paste part 3 includes a first paste region 31 formed on the surface layer 12 so as to surround and fix the plurality of photoluminescent particles 2. . As the first paste region 31 surrounds the photoluminescent particles 2 in this way, the plurality of photoluminescent particles 2 disposed on the surface layer 12 can be secondarily fixed by the cement paste part 3. have.

That is, as described above, the photoluminescent grains 2 are first fixed in a partially inserted state with respect to the surface layer 12 in the uncured state, and then by the first paste region 31 of the cement paste part 3. It can be fixed in multiple ways in a secondary fixed form.

The cement paste part 3 may include a second paste region 32 formed inside at least a portion of the plurality of voids so as to be integrally coupled with the surface layer 12 and connected to the first paste region 31. . A change in the thickness of the second paste region 32 and the cement paste portion 3 associated therewith will be described in more detail below with reference to the related drawings.

5A is an enlarged view showing an initial thickness formed by a first paste region formed on a surface layer and a cement paste poured on the surface layer in the photocatalyst applied to the surface of the photocatalyst and a method for manufacturing the same. 5B is a photocatalyst is applied to the surface of the photocatalyst according to an embodiment of the present application and in the manufacturing method thereof, some of the cement paste poured on the surface is moved to the inside of at least some of the plurality of voids to reduce the final thickness. It is an enlarged view showing the formation.

Referring to FIG. 5A, the first paste region 31 may be formed by an initial thickness t1 by cement paste poured on the surface layer 12.

In this case, the initial thickness t1 of the first paste region 31 may be a size corresponding to the protruding height of the plurality of photoluminescent particles 2. Illustratively, the size corresponding to the protruding height of the plurality of photoluminescent particles 2 does not mean only the size that is exactly the same as the protruding height of the plurality of photoluminescent particles 2, but the same size within an error range. do. In addition, the initial thickness t1 may mean a thickness measured immediately after the cement paste is poured onto the surface layer 12.

Also, referring to FIG. 5B, in the first paste region 31, the upper ends of the plurality of photoluminescent particles 2 may be exposed to the upper side of the cement paste part 3 for photoluminescence and light emission of the plurality of photoluminescent particles 2. It can be formed to a final thickness (t2). That is, the final thickness t2 of the first paste region 31 may be smaller than the protruding height of the plurality of photoluminescent particles 2. In other words, the first paste region 31 is formed by the initial thickness t1 by the cement paste poured on the surface layer 12, and then some of the poured cement paste is moved into at least some of the plurality of voids. , It may be formed to a final thickness (t2) thinner than the initial thickness (t1). 5A and 5B, the final thickness t2 may be formed to be thinner by Δa than the initial thickness t1, and accordingly, the photoluminescent grains 2 may be exposed to the outside by a thickness corresponding to Δa.

6 is an enlarged view showing that the surface of a first paste region is pressed downward by a pressing mechanism in the photocatalyst applied to the surface of the photocatalyst and a method for manufacturing the same according to an exemplary embodiment of the present disclosure.

Referring to FIG. 6, the first paste region 31 is formed by an initial thickness t1, and then the surface is pressed downward by a pressing mechanism, so that a portion of the cement paste moves into at least a portion of the plurality of voids. Alternatively, the amount may be increased compared to when the pressurizing device is not used.

The surface pressurization of the first paste region 31 by such a pressing mechanism is performed by the first paste region 31 while some of the cement paste forming the first paste region 31 permeates into the voids of the surface layer 12. It is preferable that the amount (size) of lowering the height of the surface is relatively larger than the amount (size) of lowering the upper end of the photoluminescent grains 2. Due to this relative difference, as a result, the photoluminescent grains 2 may be exposed to the outside by a thickness corresponding to Δa as shown in FIG. 5B.

For example, the pressing by the pressing mechanism may proceed in the direction of selectively pressing only the surface of the first paste region 31 without pressing the photoluminescent particles 2 as much as possible.

As another example, the pressurization by the pressurization mechanism is a small pressurization size (this pressurization size may be set in consideration of the curing progress of the surface layer 12) that prevents the phosphorescent grains 2 from being inserted downward, and this At the same time, a pressure size sufficient to promote penetration of some of the cement paste forming the first paste region 31 into the voids of the surface layer 12 may be achieved. That is, the intensity (size) of the pressure transmitted by the pressurization mechanism allows the cement paste to sufficiently permeate on the surface layer 12 so that the integrity of the cement paste portion 3 and the surface layer 12 can be improved. Although the intensity is set, it may mean an intensity such that the plurality of photoluminescent particles 2 are exposed to the outside without being inserted below the final thickness t2 of the first paste region 31. In addition, even in such a case, it would be more preferable to pressurize the photoluminescent grains 2 in a direction that selectively presses only the surface of the first paste region 31 without pressurizing the photoluminescent grains 2.

Illustratively, the pressing mechanism may include a scraper. As another example, the pressurizing mechanism may include an air blower, but is not limited thereto.

Further, referring to FIG. 6, the pressing mechanism may perform an operation for removing the cement paste attached to the plurality of photoluminescent particles 2.

In other words, if the cement paste is attached to the surface of the plurality of photoluminescent particles (2), the photoluminescence and luminous efficiency may be lowered, so the operation performed by the pressing mechanism is performed by removing the cement paste attached to the surface of the plurality of photoluminescent particles (2). And it is possible to further increase the luminous efficiency. The operation for removing the cement paste attached to the plurality of photoluminescent particles 2 may be an operation in which a force combined with a downward pressing force and a horizontal force is applied. Exemplarily, the pressing mechanism sweeps the surface of the cement paste part 3 at an angle like a broom sweep, so that the above-described downward pressure can also be generated and a component force acting horizontally can be generated together, so that a plurality of photoluminescent particles ( The cement paste attached to the surface of 2) can be removed.

Figure 7a is a conceptual diagram showing a photocatalytic surface-applied photoluminescent sidewalk block according to an embodiment of the present application and a photoluminescent stone in the manufacturing method thereof, Figure 7b is a photocatalyst according to an embodiment of the present application to the surface applied photoluminescent sidewalk block It is a cross-sectional view of a photoluminescent capsule including a photoluminescent pigment part and a coating part.

7A and 7B, the plurality of phosphorescent grains 2 may include at least one of a phosphorescent stone 21 and a phosphorescent capsule 22.

The phosphorescent stone 21 may be made by firing a phosphorescent pigment of high brightness at high temperature. Illustratively, the phosphorescent ore 21 may be similar to an existing commercial product, but is not limited thereto.

Meanwhile, the photoluminescent capsule 22 may include a photoluminescent pigment part 221 including a photoluminescent pigment and a coating part 222 surrounding the photoluminescent pigment part 221. In addition, the coating unit 222 is a press device used when partially inserting the photoluminescent particles 2 (phosphorescent capsules) into the surface layer 12, a pressing device used to remove foreign matter from the surface of the photoluminescent particles 2, At least a part of the phosphorescent capsule 22 is damaged due to external influences (external force action) such as other unexpected impacts, and the thickness and thickness sufficient to protect the phosphorescent pigment portion 221 from leaking to the outside of the phosphorescent capsule 22 It may be provided to have material strength. In addition, the photoluminescent pigment part 221 may include glass particles that are mixed with the photoluminescent pigment so that light scattering is induced when the photoluminescent pigment emits light. Illustratively, the glass particles may include glass powder, glass fragments, and the like. At this time, the glass particles further increase the scattering effect of light when the photoluminescent pigment emits light so that the light irradiated to the lower side of the photoluminescent capsule 22 is scattered again, thereby inducing re-irradiation to the upper side of the photoluminescent capsule 22, The luminous effect of the photoluminescent capsule 22 can be further maximized. In addition, the mixing ratio of the phosphorescent pigment and the glass particles is preferably set in a direction in which the phosphorescent capsule 22 can perform the phosphorescent and light emitting functions more smoothly.

The cement paste part 3 is formed of a material including cement and a photocatalyst. The cement paste part 3 may contain cement in the form of a cement paste. Since the cement paste has been described above, a detailed description will be omitted.

That is, the plurality of photoluminescent grains 2 disposed on the surface layer 12 may be secondarily fixed by the cement paste portion 3. At this time, as described above, the photoluminescent grains 2 are first fixed in a partially inserted state with respect to the surface layer 12 in the uncured state, and then by the first paste region 31 of the cement paste part 3. It can be fixed in multiple ways in a secondary fixed form.

In step S130, the cement paste portion 3 is formed in at least a portion of the plurality of voids so as to be integrally coupled with the surface layer 12, and a second paste area 32 connected to the first paste area 31 is formed. Can include. A change in the thickness of the second paste region 32 and the cement paste portion 3 associated therewith will be described in more detail below with reference to the related drawings.

Referring to FIG. 5A, the first paste region 31 may be formed by an initial thickness t1 by cement paste poured on the surface layer 12.

In this case, the initial thickness t1 of the first paste region 31 may be a size corresponding to the protruding height of the plurality of photoluminescent grains 2. Regarding the size corresponding to the protruding height of the plurality of photoluminescent grains 2 Since has been described above, a detailed description will be omitted.

Also, referring to FIG. 5B, in the first paste region 31, the upper ends of the plurality of photoluminescent particles 2 may be exposed to the upper side of the cement paste part 3 for photoluminescence and light emission of the plurality of photoluminescent particles 2. It can be formed to a final thickness (t2). That is, the final thickness t2 of the first paste region 31 may be smaller than the protruding height of the plurality of photoluminescent particles 2. In other words, the first paste region 31 is formed by the initial thickness t1 by the cement paste poured on the surface layer 12, and then some of the poured cement paste is moved into at least some of the plurality of voids. , It may be formed to a final thickness (t2) thinner than the initial thickness (t1). 5A and 5B, the final thickness t2 may be formed to be thinner by Δa than the initial thickness t1, and accordingly, the photoluminescent grains 2 may be exposed to the outside by a thickness corresponding to Δa.

Referring to FIG. 6, the first paste region 31 is formed by an initial thickness t1, and then the surface is pressed downward by a pressing mechanism, so that a portion of the cement paste moves into at least a portion of the plurality of voids. Alternatively, the amount may be increased compared to the non-use of the pressurization mechanism. Since the pressure on the surface of the first paste region 31 by such a pressing mechanism has been described above, detailed descriptions will be omitted.

Further, referring to FIG. 6, the pressing mechanism may perform an operation for removing the cement paste attached to the plurality of photoluminescent particles 2. Since this has been described above, a detailed description will be omitted.
