Description

The present invention relates to facilities of the upper floor (eg roof) parking anti-slip floor applicable such as self-propelled car park provided is construction in the shops.

In recent years, due to social demands such as building weight reduction and construction period shortening, the exposed waterproof construction method is often adopted for self-propelled parking lots provided on the upper floors of facilities such as stores (for example, the rooftop). .
In this type of self-propelled parking lot, not only a waterproof function but also a floor function for vehicle travel is required, so a slip-proof floor having a slip-proof layer including aggregate is formed (for example, see Patent Document 1). . Since the anti-slip layer includes aggregate, the surface of the anti-slip floor has an uneven shape, thereby improving the anti-slip performance.

JP 2007-113249 A

In the non-slip floor, when the wear due to contact with the tires of the vehicle proceeds to the waterproof layer, not only the floor function but also the waterproof function may be deteriorated. For this reason, the technique which can discover progress of wear at an early stage has been desired.
This invention is made | formed in view of such a situation, and it is providing the parking lot which can discover progress of wear at an early stage.

The present invention has a waterproof layer on a base, one or a plurality of anti-slip layers formed thereon, and a top coat layer formed thereon. The top coat layer covers the anti-slip layer, and at least one of the anti-slip layers exhibits a chromatic color that is different from the top coat layer, and its saturation Provides a non-slip floor having a higher saturation than the top coat layer.
It is preferable that the brightness of the anti-slip layer exhibiting a color different from that of the top coat layer is higher than the brightness of the top coat layer.
The top coat layer preferably exhibits an achromatic color.
In the antiskid floor of the present invention, the plurality of antiskid layers are laminated to each other, and only those closest to the waterproof layer among them exhibit a chromatic color that is a color different from the top coat layer, and the saturation is the above The chroma may be higher than the saturation of the top coat layer, and the other anti-slip layer may have the same color as the top coat layer.

The present invention provides a parking lot having a parking area where a vehicle is parked and a travel path on which the vehicle travels, wherein the anti-skid floor is formed in the parking area and the travel path. .
The parking lot of this invention is good also as a structure where the non-slip floor formed in the said travel path has many anti-slip layers compared with the anti-slip floor formed in the said parking area.

  In the present invention, a waterproof layer is formed on a base, one or more anti-slip layers are formed thereon, and a top coat layer is formed on the base layer to conceal the anti-slip layer. Resin containing aggregate, at least one of the anti-slip layers has a chromatic color that is different from the top coat layer, and the chroma is higher than the chroma of the top coat layer The construction method is provided.

According to the present invention, since the anti-slip layer exhibits a color different from that of the top coat layer, it can be visually confirmed when the top coat layer is worn away by running of the vehicle and the anti-slip layer is exposed. For example, if the topcoat layer is gray and the anti-slip layer is green, when the wear reaches the anti-slip layer, the color of the part changes from gray to green, so that the wear part can be visually recognized easily. I can confirm.
For this reason, it is possible to repair by detecting the wear of the top coat layer at an early stage and forming the top coat layer again at the exposed portion of the anti-slip layer.
Therefore, it is possible to prevent wear from reaching the waterproof layer and maintain the waterproof performance for a long period of time. Since the waterproof performance can be maintained for a long time, the life cycle cost of the building can be reduced.
Further, since the repair can be performed only when the repair becomes necessary due to the progress of wear, it is possible to avoid an increase in the maintenance cost due to the unnecessary repair.
According to the present invention, when wear reaches the anti-slip layer, it is possible to repair the anti-slip layer again on the worn part, so that anti-slip performance can be maintained and safety can be ensured. . In addition, since the wear of the topcoat layer can be repaired immediately, the protection performance of the topcoat layer can be maintained and the antiskid layer can be prevented from being deteriorated by ultraviolet rays or the like.
Thus, according to the present invention, it is possible to maintain high waterproof performance and anti-slip performance at low cost.

The foundation 2 is formed by placing concrete, for example.
The primer layer 10 is formed in order to ensure the adhesive force of the waterproof layer 20 with respect to the base 2, and for example, a primer made of urethane resin, epoxy resin, or the like can be used.
Examples of the primer application method include application by a roller, a brush, etc .; spraying by a spray gun.
The amount of primer applied is, for example, 0.15 to 0.2 kg / m ² .

As a material for the waterproof layer 20, polyurethane resin, epoxy resin, polyester resin, vinyl ester resin, methyl methacrylate resin, polyurea resin, and the like can be used, and polyurethane resin is particularly preferable.
As the polyurethane resin, for example, a two-component polyurethane resin composed of a main component containing polyisocyanate and a curing agent containing a polyfunctional active hydrogen compound reactive with an isocyanate group is preferable.

As the isocyanate compound contained in the main agent, an isocyanate group-terminated prepolymer obtained by a reaction between a polyisocyanate compound and a polyol is preferable.
The polyisocyanate compound is not particularly limited. For example, diphenylmethane-4,4′-diisocyanate (MDI), carbodiimide-modified diphenylmethane diisocyanate (liquid MDI), polymethylene polyphenyl isocyanate (crude MDI), 2,4-tolylene diisocyanate Examples include low molecular weight isocyanate compounds such as (2,4-TDI), 2,6-tolylene diisocyanate (2,6-TDI), xylylene diisocyanate (XDI), hexamethylene diisocyanate. These may be used alone or in combination of two or more.

As the polyol, polyether polyol, polyester polyol or the like can be used.
Examples of polyether polyols include polyether polyols obtained by addition polymerization of one or more of ethylene oxide, propylene oxide, butylene oxide and the like, polytetramethylene ether glycol obtained by ring-opening polymerization of tetrahydrofuran, and the like.

  Specific examples of the polyester polyol include ethylene glycol, propylene glycol, butanediol, pentanediol, hexanediol, glycerin, trimethylolpropane, and other low molecular polyols, glutaric acid, adipic acid, and sebacic acid. , Terephthalic acid, isophthalic acid, dimer acid, polyester polyol obtained by condensation polymerization with one or more of other low molecular dicarboxylic acids or oligomeric acids, and ring-opening polymerization of caprolactone.

  The polyol is not particularly limited as long as it has two or more hydroxyl groups, and examples thereof include general polyols such as polyether polyols, polyester polyols, and polytetramethylene glycol; and flame-retardant polyols such as phosphorus-containing polyols. These polyols may be used alone or in combination of two or more.

  If necessary, additives such as a plasticizer, a curing catalyst, a filler, an antioxidant, a flame retardant, a stabilizer, an ultraviolet absorber, a surfactant, and a coloring pigment may be added to the waterproof layer 20. .

The thickness of the waterproof layer 20 can be 1.5 mm or more, for example. Thereby, sufficient thickness can be given to the waterproof layer 20, and waterproof performance can be improved.
The thickness of the waterproof layer 20 is preferably 3 mm or less in consideration of ease of construction and construction cost.

The waterproof layer 20 is formed by spraying and applying a material resin toward the primer layer 10 using, for example, a two-component collision mixing type spray coating apparatus (two-component collision mixer) equipped with a high-pressure spray gun. Can be formed.
The coating amount of the material resin of the waterproof layer 20 can be, for example, 1.5 kg / m ² or more (preferably 1.5 to 3 kg / m ² ).
The waterproof layer 20 may be formed of a one-pack type polyurethane material.

  The antiskid layer 30 contains the aggregate 32 in the base resin 31, for example. When the anti-slip layer 30 includes the aggregate 32, the surface of the anti-slip layer 30 has an uneven shape, and the surface of the anti-slip floor 1 has an uneven shape according to the surface shape of the anti-slip layer 30, thereby improving the anti-slip performance.

As the base resin 31, polyurethane resin, polyurethane resin, epoxy resin, polyester resin, vinyl ester resin, methyl methacrylate resin, polyurea resin, and the like can be used.
In particular, the polyurethane resin has an advantage that it has an excellent waterproof effect and also has high adhesion to the waterproof layer 20 (made of polyurethane resin).
Specific examples of the polyurethane resin include those listed as the material of the waterproof layer 20, for example.

The thickness of the anti-slip layer 30 (thickness T1 shown in FIG. 1B) can be, for example, 0.4 mm or more (preferably 0.6 to 1 mm). Thereby, it is possible to give the anti-slip layer 30 a sufficient thickness and to prevent the abrasion from reaching the waterproof layer 20. Construction can be facilitated by setting the thickness (thickness T1) of the anti-slip layer 30 to 1 mm or less.
The thickness T1 is the thickness of the anti-slip layer 30 excluding the protruding portion 33 from the surface.
The total thickness T2 of the anti-slip layer 30 including the protrusion 33 can be set to 0.6 to 1.5 mm, for example.

As the aggregate 32, for example, cinnabar, mineral (basalt, etc.), natural oxalic material such as river sand, ceramic, etc. are suitable. The average particle diameter of the aggregate 32 can be set to 0.4 mm to 2 mm, for example.
The amount of the aggregate 32 added to the anti-slip layer 30 can be 50 to 200 parts by mass with respect to 100 parts by mass of the base resin.
The aggregate 32 is contained in the base resin 31 in a dispersed state.
The average particle diameter can be measured by a laser diffraction / scattering method or the like, and can be measured using, for example, a particle size distribution measuring apparatus SALD-2000J manufactured by Shimadzu Corporation.

  The anti-slip layer 30 can be visually distinguished from the top coat layer 40 due to the difference in color by using a material that exhibits a color different from that of the top coat layer 40.

The anti-slip layer 30 exhibits a chromatic color. The saturation of the anti-slip layer 30 is made higher than the saturation of the top coat layer 40. Thus, the anti-slip layer 30 can be easily identified when the top coat layer 40 is worn and the anti-slip layer 30 is exposed.
The lightness of the anti-slip layer 30 is preferably higher than the lightness of the topcoat layer 40. This makes it easy to identify the exposed anti-slip layer 30.
The hue of the anti-slip layer 30 is not particularly limited, but green, blue, yellow, red, and the like are preferable from the viewpoint of discrimination.

The difference in color can be expressed by the CIE 1976 L ^* a ^* b ^* color system (conforming to JIS Z8729).
In the L ^* a ^* b ^* color system, lightness is represented by L ^* , and hue and saturation are represented by a ^* and b ^* .
The lightness L ^* takes a numerical value from 0 to 100, and the larger the numerical value, the brighter the brightness. That is, the lightness L ^* is closer to black as it is closer to 0, for example, and closer to 100 as it is closer to white.
a ^* represents a red-green direction component. If the negative value increases, it becomes closer to green, and if the positive value increases, it becomes closer to red.
b ^* represents the direction component from blue to yellow. The larger the negative value, the closer to blue, and the larger the positive value, the closer to yellow.
The saturation of a ^* and b ^* increases as the numerical value (absolute value) increases. When a ^* = 0 and b ^* = 0, an achromatic color is obtained.

A color in which at least one of a ^* and b ^* is not 0 is a chromatic color in principle. However, even if at least one of a ^* and b ^* is not 0, if coloring cannot be confirmed by visual judgment (for example, when it can be visually judged as white, black, or gray), it is determined that the color is achromatic. it can.
For example, if the absolute values of a ^* and b ^* are both less than 10, it can be determined that the achromatic color is substantially achromatic if the coloring cannot be visually confirmed.

If the color of the anti-slip layer 30 is represented by L ^* ₁ , a ^* ₁ , b ^* ₁ , and the color of the topcoat layer 40 is represented by L ^* ₂ , a ^* ₂ , b ^* ₂ , the anti-slip layer 30 and The color difference ΔE with the top coat layer 40 is obtained by the following equation.
ΔE = (ΔL ^{* 2} + Δa ^{* 2} + Δb ^{* 2} ) ^1/2
ΔL ^* is L ^* _1- L ^* ₂ , Δa ^* is a ^* _1- a ^* ₂ , and Δb ^* is b ^* _1- b ^* ₂ .

The anti-slip layer 30 preferably has a color difference ΔE with respect to the top coat layer 40 of 10 or more, and more preferably 20 or more.
By setting the color difference ΔE within this range, the anti-slip layer 30 can be easily identified when the top coat layer 40 is worn and the anti-slip layer 30 is exposed.

The absolute value of at least one of a ^* and b ^* of the anti-slip layer 30 is preferably 30 or more, and more preferably 40 or more.
By setting the absolute value of at least one of a ^* and b ^* within this range, the anti-slip layer 30 can be easily identified when the top coat layer 40 is worn and the anti-slip layer 30 is exposed.

In the present embodiment, C ^* [= (a ^{* 2} + b ^{* 2} ) ^1/2 ] can be employed as an index of saturation.
The fact that the saturation of the anti-slip layer 30 is higher than the saturation of the top coat layer 40 may be synonymous with the fact that C ^* of the anti-slip layer 30 is higher than C ^* of the top coat layer 40.

C ^* [= (a ^{* 2} + b ^{* 2} ) ^1/2 ] of the anti-slip layer 30 is preferably 30 or more, and more preferably 40 or more.
By setting C ^* within this range, the anti-slip layer 30 can be easily identified when the top coat layer 40 is worn and the anti-slip layer 30 is exposed.

The lightness L ^* of the anti-slip layer 30 is preferably 50 or more, and more preferably 60 or more.
By setting the lightness L ^* within this range, the anti-slip layer 30 can be easily identified when the top coat layer 40 is worn and the anti-slip layer 30 is exposed.

For the measurement of L ^* , a ^* , b ^* and C ^* , for example, a spectrocolorimeter CM-5 manufactured by Konica Minolta can be used. The color measurement can also be performed according to JIS Z8729 (2004). Moreover, you may employ | adopt the determination by the sensory test with a naked eye. For example, if the chromatic color cannot be confirmed by visual judgment, it can be determined as an achromatic color.

In order to adjust the color of the anti-slip layer 30, a colorant may be added as necessary. A pigment or dye can be used as the colorant.
Examples of the pigment include an organic pigment and an inorganic pigment. Examples of organic pigments include azo pigments, phthalocyanine pigments, isoindolinone / isoindoline pigments, quinacridone pigments, dioxazine pigments, diketopyrrolopyrrole pigments, and quinophthalone pigments. Specific examples include quinacridone red, disazo yellow, phthalocyanine blue, phthalocyanine green, isoindolinone yellow, dioxazine violet, and 2,9-dimethylquinacridone.

Examples of inorganic pigments include oxides such as titanium oxide, red iron oxide, zinc oxide, chromium oxide, iron black, and composite oxides; carbon such as carbon black; chromate such as yellow lead and molybdate orange; Ferrocyanides; sulfides such as cadmium yellow, cadmium red, and zinc sulfide; sulfates such as barium sulfate; hydrochlorides; silicates such as ultramarine; carbonates such as calcium carbonate; phosphates such as manganese violet; yellow Examples thereof include hydroxides such as iron oxide.
Examples of the composite oxide include titanium yellow, zinc-iron brown, titanium / cobalt green, cobalt green, cobalt blue, copper-chromium black, and copper-iron black.

  Dyes are solvent dyes, acid dyes, direct dyes, basic dyes, reactive dyes, mordant dyes, acid mordant dyes, disperse dyes, vat dyes (slen dyes), sulfur dyes, sulfur vat dyes, azoic dyes, fluorescent dyes There are dyes.

For the formation of the anti-slip layer 30, for example, a method including a first resin application step, an aggregate application step, and a second resin application step can be employed.
The first resin application step is a step of applying an uncured material resin on the waterproof layer 20.
The aggregate spraying process is a process of spraying the aggregate 32 to the uncured resin applied in the first resin coating process.
The second resin application step is a step of applying an uncured material resin on the resin and the aggregate 32 applied in the first resin application step. In the second resin application step, the same material resin as that applied in the first resin application step can be used. The applied material resin is integrated with the resin in the first resin application step to become the base resin 31.
For application of the material resin, for example, a two-component collision mixing type spray coating apparatus (two-component collision mixer) equipped with a high-pressure spray gun can be used.

The anti-slip layer 30 can be formed, for example, by spraying and applying a polyurethane material using a two-component collision mixing type spray coating apparatus (two-component collision mixer) equipped with a high-pressure spray gun.
The coating amount of the base resin 31 constituting the anti-slip layer 30 is, for example, 0.4 kg / m ² or more (preferably 0.6 to 1 kg / m ² ).

The top coat layer 40 is a layer (outermost layer) located on the surface of the anti-slip floor 1 and is formed for the purpose of protecting the anti-slip layer 30 and improving the appearance of the anti-slip floor 1. The top coat layer 40 preferably has a function of blocking ultraviolet rays or the like and preventing the anti-slip layer 30 from deteriorating.
An acrylic resin (for example, acrylic urethane resin) can be used for the top coat layer 40. For the topcoat layer 40, a fluororesin, a silicon resin, or the like can be used, but an acrylic resin, particularly an acrylic urethane resin is preferable from the viewpoint of protection performance.

The thickness of the top coat layer 40 can be, for example, 50 μm or more (preferably 70 μm or more). Thereby, the effect of protecting the anti-slip layer 30 can be enhanced. The thickness of the top coat layer 40 is preferably 200 μm or less (preferably 100 μm or less) in consideration of ease of construction.
The topcoat layer 40 can be formed, for example, by application with a spray gun or a roller. The coating amount of the material resin for the top coat layer 40 is, for example, 0.1 kg / m ² or more (preferably 0.15 to 0.25 kg / m ² ).

  The topcoat layer 40 exhibits a color different from that of the anti-slip layer 30 as described above. The saturation of the top coat layer 40 is set lower than the saturation of the anti-slip layer 30. The brightness of the top coat layer 40 is preferably lower than the brightness of the anti-slip layer 30.

It is preferable that the top coat layer 40 has a thickness that can conceal the anti-slip layer 30. That is, it is preferable that the anti-slip layer 30 is concealed by the top coat layer 40 so that the color of the anti-slip layer 30 cannot be identified.
For example, when the top coat layer 40 is gray and the anti-slip layer 30 is green, it is preferable that the anti-skid floor 1 in a state in which no wear occurs has a gray color in appearance.

The absolute value of a ^* is preferably less than 30, and more preferably 20 or less. The absolute value of b ^* is preferably less than 30, and more preferably 20 or less.
By setting the absolute values of a ^* and b ^* within this range, the anti-slip layer 30 can be easily identified when the top coat layer 40 is worn and the anti-slip layer 30 is exposed.

C ^* (= (a ^* ) ² + (b ^* ) ² ) ^1/2 ) serving as a saturation index is preferably less than 30, more preferably 20 or less.
By setting C ^* within this range, the anti-slip layer 30 can be easily identified when the top coat layer 40 is worn and the anti-slip layer 30 is exposed.

  For example, the topcoat layer 40 can be achromatic (for example, gray). When the top coat layer 40 is achromatic, the anti-slip layer 30 can be easily identified when the anti-slip layer 30 is exposed.

The lightness L ^* of the topcoat layer 40 is preferably less than 50, and more preferably 40 or less.
By setting the lightness L ^* within this range, the anti-slip layer 30 can be easily identified when the top coat layer 40 is worn and the anti-slip layer 30 is exposed.

The top coat layer 40 preferably has a concealment rate of 80% or more, and more preferably 90% or more.
By setting the concealment rate within this range, the anti-slip layer 30 can be easily identified when the top coat layer 40 is worn and the anti-slip layer 30 is exposed.
The concealment rate is, for example, a 1 mm thick resin coated on a concealment rate test paper based on JIS K5600 4-1 method B, and the tristimulus value Y of the coated film is expressed as white (YW) and black ( YB) Measured in each case, and the concealment rate YB / YW is calculated as a percentage.

The top coat layer 40 preferably has a visible light transmittance of 10% or less, and more preferably 5% or less.
By setting the visible light transmittance within this range, the anti-slip layer 30 can be easily identified when the top coat layer 40 is worn and the anti-slip layer 30 is exposed.

In order to adjust the color of the topcoat layer 40, a colorant may be added as necessary. Examples of the colorant include those listed as colorants that can be used for the anti-slip layer 30.
For example, the topcoat layer 40 can be achromatic (for example, gray). When the top coat layer 40 is achromatic, the anti-slip layer 30 can be easily identified when the anti-slip layer 30 is exposed.
Examples of gray pigments include pigments containing carbon black and titanium oxide.
By using this pigment, it is possible to increase the concealment rate and to easily identify the anti-slip layer 30 when the top coat layer 40 is worn and the anti-slip layer 30 is exposed.

In the anti-slip floor 1, since the anti-slip layer 30 has a color different from that of the top coat layer 40, when the top coat layer 40 is worn away by running of the vehicle and the anti-slip layer 30 is exposed, this can be visually confirmed. . FIG. 2 shows a state in which the top coat layer 40 is worn and a partial region (exposed region 34) of the surface of the anti-slip layer 30 is exposed to the worn portion.
For example, when the top coat layer 40 is gray and the anti-slip layer 30 is green, when the wear reaches the anti-slip layer 30, the color of the part changes from gray to green. Can be easily confirmed.
For this reason, the wear of the topcoat layer 40 can be detected early, and repair can be performed by forming the topcoat layer 40 again in the exposed region 34 of the anti-slip layer 30.
Therefore, it is possible to prevent wear from reaching the waterproof layer 20 and maintain the waterproof performance for a long time. Since the waterproof performance can be maintained for a long time, the life cycle cost of the building can be reduced.
Further, since the repair can be performed only when the repair becomes necessary due to the progress of wear, it is possible to avoid an increase in the maintenance cost due to the unnecessary repair.

In the anti-slip floor 1, when the wear reaches the anti-slip layer 30, the anti-slip layer 30 can be repaired immediately such as forming the anti-slip layer 30 again on the worn part, so that the anti-slip performance can be maintained and the safety can be ensured. it can.
Further, since the wear of the top coat layer 40 can be repaired immediately, the protection performance of the top coat layer 40 can be maintained, and the anti-slip layer 30 can be prevented from being deteriorated by ultraviolet rays or the like.
Thus, the anti-slip floor 1 can maintain high waterproof performance and anti-slip performance at low cost.

Conventionally, a color similar to that of the top coat layer is often used for the anti-slip layer. The same color as the topcoat layer was often used for the anti-slip layer, because the use of the same color reduces the restrictions during construction and increases the efficiency of construction work. is there.
In the anti-slip floor 1 shown in FIG. 1, the anti-slip layer 30 and the top coat layer 40 have different colors. Therefore, the anti-slip layer 30 needs to be applied with care so as not to be exposed on the surface of the anti-slip floor 1. For this reason, although it cannot be said that the construction is easier than in the prior art, maintaining the waterproof performance and the anti-slip performance at a low cost is a great advantage that more than compensates for the construction.

FIG. 3 is a cross-sectional view showing a slip-proof floor 61 which is a second embodiment of the slip-proof floor according to the present invention.
The anti-slip floor 61 shown here is different from the anti-slip floor 1 of the first embodiment shown in FIG. 1 in that it has two anti-slip layers 60 (first anti-slip layer 60A and second anti-slip layer 60B). The first anti-slip layer 60A is formed on the second anti-slip layer 60B.

  The two anti-slip layers 60 (60A, 60B) are laminated to each other, and at least one of the two anti-slip layers 60 (60A, 60B) is similar to the anti-slip layer 30 of the first embodiment. It exhibits a color different from (for example, chromatic colors such as green, blue, yellow, and red). For this reason, the topcoat layer 40 (for example, an achromatic color such as a gray color) can be visually identified by the difference in color.

The anti-slip layer 60A has a thickness excluding protruding portions (thickness T1 in FIG. 1 (B)), a thickness including protruding portions ((thickness T2 in FIG. 1 (B)), an average particle diameter of aggregate, an added amount, and the like. Can adopt the conditions listed in the description of the anti-slip layer 30 shown in FIG.
For example, the thickness T1 (thickness excluding the protruding portion) of the anti-slip layer 60A can be 0.4 mm to 1 mm, and the thickness T2 (total thickness including the protruding portion) of the anti-slip layer 60A is 0.6 to 1.5 mm. It can be.
Similarly, the conditions listed in the description of the anti-slip layer 30 can be adopted for the anti-slip layer 60B.

  Since the anti-slip floor 61 has the two anti-slip layers 60 (60A, 60B), the total thickness of the anti-slip layer 60 is thicker than that of the anti-slip floor 1 of FIG. Therefore, it is possible to avoid the wear from reaching the waterproof layer 20 and reliably prevent the waterproof performance from deteriorating.

In the anti-slip floor 61, only the anti-slip layer 60B on the lower layer side (that is, the one closest to the waterproof layer 20) of the two anti-slip layers 60 is different from the top coat layer 40 (for example, green, blue, yellow, red, etc.). The upper anti-slip layer 60 </ b> A may be configured to exhibit a color similar to that of the top coat layer 40 (for example, an achromatic color such as a gray color).
As a result, it is possible to confirm when the repair becomes necessary due to the wear approaching the waterproof layer 20, so that it is possible to avoid an increase in maintenance cost due to unnecessary repair.
For example, when two colors are compared, the same color is a difference of a ^* in the above L ^* a ^* b ^* color system of 5 or less and a difference of b ^* of 5 or less. Color.

FIG. 4 is a cross-sectional view showing a slip-proof floor 71 which is a third embodiment of the slip-proof floor according to the present invention.
The anti-slip floor 71 shown here has three anti-slip layers 70 (first anti-slip layer 70A, second anti-slip layer 70B, and third anti-slip layer 70C), and the anti-skid floor 1 of the first embodiment shown in FIG. And different.
The second anti-slip layer 70B is laminated on the third anti-slip layer 70C, and the first anti-slip layer 70A is laminated on the second anti-slip layer 70B.

  The three anti-slip layers 70 (70A, 70B, 70C) are laminated together, and at least one of the three anti-slip layers 70 (70A, 70B, 70C) is the same as the anti-slip layer 30 of the first embodiment. It exhibits a color different from that of the top coat layer 40 (for example, chromatic colors such as green, blue, yellow, and red). For this reason, the topcoat layer 40 (for example, an achromatic color such as a gray color) can be visually identified by the difference in color.

  The anti-slip layer 70A has a thickness excluding protruding portions (thickness T1 in FIG. 1 (B)), a thickness including protruding portions ((thickness T2 in FIG. 1 (B)), an average particle diameter of aggregates, an added amount, and the like. Can adopt the conditions listed in the description of the anti-slip layer 30 shown in Fig. 1. Similarly, the conditions listed in the description of the anti-slip layer 30 can be adopted for the anti-slip layers 70B and 70C.

  Since the anti-slip floor 71 has the three anti-slip layers 30 (30A, 30B, 30C), the total thickness of the anti-slip layer 70 is increased. Accordingly, it is possible to avoid wear on the waterproof layer 20 and to further prevent the deterioration of the waterproof performance.

In the anti-slip floor 71, only the anti-slip layer 70C on the lower layer side (that is, the closest to the waterproof layer 20) among the three anti-slip layers 70 is different in color from the top coat layer 40 (for example, green, blue, yellow, red, etc.) The two anti-slip layers 70A and 70B on the upper layer side may be configured to exhibit a color similar to that of the top coat layer 40 (for example, an achromatic color such as a gray color).
As a result, it is possible to confirm when the repair becomes necessary due to the wear approaching the waterproof layer 20, so that it is possible to avoid an increase in maintenance cost due to unnecessary repair.

In the anti-slip floors 61 and 71 shown in FIGS. 3 and 4, the anti-slip layer (hereinafter referred to as a different color anti-slip layer) that exhibits a color different from the top coat layer among the plurality of anti-slip layers is not limited to the lowermost layer. For example, all of the anti-slip layers of the anti-slip floors 61 and 71 may be different color anti-slip layers. Further, only the two anti-slip layers 70 on the lower layer side among the three anti-slip layers 70 of the anti-slip floor 71 may be different color anti-slip layers.
In addition, the number of anti-slip layers is not limited to the illustrated example, and the anti-slip layer may be composed of four or more layers.

Although it does not specifically limit as a structure used as the construction object of the anti-slip floor 1, A self-propelled parking lot is mentioned as an example. FIG. 5 is a plan view showing a parking lot 100 as an example of the parking lot.
The parking lot 100 may be configured to have only one parking floor, or may be a three-dimensional parking lot having a plurality of parking floors.

  The parking lot 100 may be a parking lot provided on the upper floor (for example, the rooftop) of a facility or store. Since the parking lot provided on the upper floor is required to have high waterproof performance, the present invention can sufficiently exhibit its characteristics when applied to this type of parking lot.

The parking lot 100 includes an approach path 101 (traveling path) that guides the vehicle 110, a parking floor 102, and an exit path 103 (traveling path) from which the vehicle 110 exits.
The parking floor 102 has, for example, a substantially rectangular shape (rectangular shape) in a plan view, and a first parking area 111 having a substantially rectangular shape (rectangular shape) in a plan view is provided in the center, and an annular traveling around which the vehicle can travel. A roadway 106 (traveling road) is secured.
On the outer side of the traveling road 106, second to fifth parking areas 112 to 115 are secured at positions facing each side of the outer peripheral edge of the first parking area 111. In the parking areas 111 to 115, a plurality of parking sections 116 for one vehicle are arranged.

The traveling road 106 is formed so as to surround the first parking area 111, and has a substantially rectangular shape (rectangular shape) in plan view corresponding to the outer peripheral shape of the first parking area 111.
The traveling road 106 includes a first straight portion 106a that is one of the two long sides, a second straight portion 106b that is one of the two short sides and is adjacent to the first straight portion 106a, and the other length. A third straight line portion 106c adjacent to the second straight line portion 106b and a fourth straight path 106d adjacent to the third straight line portion 106c on the other short side.
The first straight portion 106 a corresponds to the long side closer to the approach path 101 and the exit path 103 out of the two long sides.
On the traveling road 106, the vehicle 110 can travel clockwise (in the order in which the first to fourth straight portions 106a to 106d are arranged).

A bent portion that is a connecting portion between the first straight portion 106a and the second straight portion 106b is referred to as a first bent portion 107a. A bent portion that is a connecting portion between the second straight portion 106b and the third straight portion 106c is referred to as a second bent portion 107b. A bent portion that is a connecting portion between the third straight portion 106c and the fourth straight portion 106d is referred to as a third bent portion 107c. A bent portion that is a connecting portion between the fourth straight portion 106d and the first straight portion 106a is referred to as a fourth bent portion 107d.
The approach path 101 is connected to the first bent portion 107a.
The exit path 103 is connected to the fourth bent portion 107d.

When the vehicle 110 enters the parking floor 102, the vehicle 110 passes through the approach path 101, enters the second straight portion 106b through the first bent portion 107a, travels clockwise on the traveling road 106, and parks. Park in any of the parking sections 116 in the areas 111-115.
When the vehicle 110 enters the traveling vehicle path 106 from the approach path 101, the vehicle 110 can temporarily stop in the stop area 101a for safety confirmation.
The stop area 101a is a terminal portion of the approach road 101, and is an area for one vehicle before the boundary 108a (the boundary between the approach road 101 and the traveling roadway 106).

When the vehicle 110 exits the parking floor 102, the vehicle 110 exits the parking section 116, travels clockwise on the traveling road 106, enters the exit path 103 via the fourth bent portion 107d, and exits 103. Pass through the parking lot 100.
When the vehicle 110 enters the exit path 103 from the fourth bent portion 107d, the vehicle 110 can temporarily stop in the stop area 106e for safety confirmation.
The stop area 106e is a part of the traveling road 106 and is an area for one vehicle before the boundary 108b (the boundary between the traveling road 106 and the exit road 103).

In the parking lot 100, any of the non-slip floors 1, 61, 71 can be applied to the entire surface of the approach path 101, the parking floor 102, and the exit path 103.
In the parking lot 100, an antiskid floor having the same structure may be constructed over the entire area. However, as shown below, a plurality of antiskid floors may be used for each area.

In the parking lot 100, there are a part where the wear is likely to occur due to the traveling of the vehicle 110 and a part where the wear is difficult to occur.
For example, in the parking section 116, since the vehicle 110 travels at a low speed, wear due to contact with tires is relatively difficult to occur.
On the traveling road 106, the approach road 101, and the exit road 103, the vehicle 110 travels at a relatively high speed, and therefore wear easily occurs due to contact with the tire.
In particular, the stop regions 101a and 106e and the bent portions 107a to 107d are likely to be worn when the vehicle 110 stops, leaves, or runs on a curve.

The parking lot 100 has a slip-proof floor 61 (see FIG. 3) or a slip-proof floor 71 (see FIG. 4) on a travel path (for example, the travel road path 106, the approach path 101, and the exit path 103) that is an area in which wear is likely to occur. ) Can be constructed.
Specifically, the anti-skid floor 71 (see FIG. 4) is applied to areas where the wear easily occurs (the stop areas 101a and 106e and the bent portions 107a to 107d), and the anti-slip is used on the road except for the areas. A floor 61 (see FIG. 3) can be applied.
In an area other than the travel path (for example, the parking areas 111 to 115), the antiskid floor 1 (see FIG. 1) can be constructed.

According to such a structure, the fall of the waterproof performance and anti-slip performance in this area | region can be prevented by constructing the anti-slip floors 61 and 71 which have a some anti-slip layer in the area | region where wear tends to occur.
On the other hand, in a region where abrasion is difficult to occur, by constructing the anti-skid floor 1 having one anti-slip layer, the construction can be facilitated, the construction cost can be reduced, and the maintenance frequency can be reduced by reducing the frequency of repairs.
In this way, maintaining the waterproof and anti-slip performance and reducing the cost can be achieved by using different anti-slip floors with different numbers of anti-slip layers according to the likelihood of wear.

The anti-slip floors 61 and 71 constructed in the region where the wear is likely to occur are different color anti-slip layers from only one of the plurality of anti-slip layers closest to the waterproof layer 20 (anti-slip layers 60B and 70C), and other anti-slip layers are used. A color similar to that of the top coat layer 40 (for example, an achromatic color such as a gray color) can be used.
As a result, in the region (antislip floors 61, 71) where wear is likely to occur, an antislip layer of the same color as the topcoat layer 40 is provided between the topcoat layer 40 and the different color antislip layer.
For this reason, the time when the different color anti-slip layer is exposed in the region where the wear is likely to occur (anti-slip floors 61 and 71) and the time when the different color anti-slip layer is exposed in the region where the wear is difficult to occur (anti-slip floor 1) can be made closer. . If the repair time for both areas can be made the same, further maintenance costs can be reduced.

In the above-described example, the anti-slip floors 61 and 71 having two or three anti-slip layers are applied to the travel path (the travel vehicle path 106, the approach path 101, and the exit path 103), and other areas (parking areas 111 to 111). 115), the anti-skid floor 1 having one anti-slip layer is applied. If the number of anti-slip layers of the anti-slip floor in the traveling area is larger than the number of anti-slip layers in the parking area, the anti-slip floor in each area is used. The number of layers is not limited to the illustrated example.
For example, the number of anti-slip layers on the travel path (traveling vehicle path 106, approach path 101, and exit path 103) is 3 or more, and the number of anti-slip layers in areas other than the travel path (parking areas 111 to 115) is 2. There may be.

In a structure having two or more anti-slip layers (for example, anti-slip floors 61 and 71 shown in FIGS. 3 and 4), two or more of the anti-slip layers may have different chromatic colors.
For example, in the anti-slip floor 61 shown in FIG. 3, the top coat layer 40 is achromatic such as gray, the upper anti-slip layer 60A is chromatic, for example, green, and the lower anti-slip layer 60B is the anti-slip layer 60A. It can be a different chromatic color, for example red.
According to this configuration, when the topcoat layer 40 is lost due to wear, the color of the portion changes from gray to green. When the wear progresses and the upper side anti-slip layer 60A is lost, the color of the portion is changed. Turns red. Therefore, the progress of wear can be confirmed by the color of the exposed anti-slip layer.
