  However, the waterproof floor structure used for conventional rooftop parking lots may differ between expected and actual usage depending on the usage exceeding the regulations for driving a car. Since the car travels repeatedly, the progress of wear of the top coat layer and the anti-slip layer is earlier than expected, and if this state is overlooked, the wear reaches the waterproof layer below the anti-slip layer and water leakage occurs. There was a problem. In that case, since the time and cost required for the repair become enormous, it is required to plan maintenance so that the waterproof layer is not repaired, but there is no suitable method, and there is room for improvement in that respect. .

  The present invention has been made in view of the above-described problems, and it is possible to suppress repair of the waterproof layer, and it is possible to easily determine the repair timing and repair site by visual inspection, and the time required for repair. Another object of the present invention is to provide a waterproof floor structure with a maintenance sign that can reduce costs and costs.

In order to achieve the above object, in the waterproof floor structure provided with the maintenance sign according to the present invention, a waterproof layer provided on a slab of a rooftop parking lot, a slip-proof layer provided on the waterproof layer, A waterproof floor structure having a maintenance sign having a laminated structure having a top coat layer for protecting the surface, wherein the anti-slip layer includes a portion having a plurality of layers formed at least in a layered manner in the rooftop parking lot. And the middle layer of the anti-slip layer of the plurality of layers is a colored layer having a different color from the other layers, and the upper layer and the lower layer of the anti-slip layer are composed of a plurality of layers. It is said.
The colored layer may be colored green.
Furthermore, other layers located above the colored layer in the anti-slip layer may be colored gray.

  In the present invention, the colored layer is exposed when the layer above the colored layer of the laminated structure constituting the waterproof floor is worn away by traveling of an automobile or the like. And since the color of a colored layer and other parts of a laminated structure differs, it becomes easy to distinguish the colored layer exposed by abrasion with respect to the other color part of another layer. In other words, by providing a colored layer with a color different from that of the other parts of the laminated structure on at least a part of the upper anti-slip layer of the waterproof layer, an upper layer than the colored layer according to the usage frequency and usage situation of the rooftop parking lot When the surface is peeled off by abrasion, the colored layer is exposed on the surface side, and the exposed portion of the colored layer becomes a portion whose color has changed on the waterproof floor. Since the colored layer is disposed on the upper layer side of the waterproof layer, the waterproof layer is not worn in the state where the colored layer is exposed. For this reason, the colored layer becomes a maintenance sign for determining the repair site and the repair timing when the color-changed portion (exposed portion of the colored layer) appears. Therefore, in order to confirm the repair site and the repair time, the exposed maintenance sign can be easily confirmed visually, even if it is not an administrator who has technical knowledge as in the past.

  Specifically, only the colored layer portion where the colored layer is exposed on the surface of the waterproof floor is confirmed by daily inspection, and the waterproof floor damaged by abrasion is periodically repaired. In this case, the waterproof layer can be repaired before it wears out, and only the repair of the anti-slip layer and the top coat layer is required. It becomes unnecessary, and the life cycle cost can be reduced.

Further, in the waterproof floor structure provided with the maintenance sign according to the present invention, a waterproof layer made of urethane resin provided on the slab of the rooftop parking lot, a slip-proof layer made of urethane resin provided on the waterproof layer, and A top coat layer that protects the surface of the anti-slip layer , and the anti-slip layer includes a plurality of layers, and the layer located in an intermediate portion of the plurality of anti-slip layers includes It has a colored layer formed in a layer shape with a color different from other parts, and the upper layer and the lower layer of the antiskid layer are composed of a plurality of layers, and the colored layer is obtained by mixing an antiskid material with a colored toner. It is characterized by being formed.

  In this case, the colored layer can be easily formed by mixing the anti-slip material with a colored toner and applying it by spraying or the like. Even when the anti-slip layer is formed of a plurality of layers, a colored layer can be provided at any position of the plurality of layers.

  Further, in the waterproof floor structure provided with the maintenance sign according to the present invention, the colored layer is preferably thicker than the other portions in the running range of the automobile in the rooftop parking lot than the other portions. .

  According to the present invention, in the roof parking lot, the running part of the automobile, which is greatly damaged due to the abrasion of the waterproof floor, is formed to have a thicker thickness on the colored layer than the other parts. It is possible to extend the period until the signature is issued.

According to the waterproof floor structure provided with the maintenance sign of the present invention, it becomes possible to suppress the repair of the waterproof layer by checking the repair time before the waterproof layer is damaged due to wear, and the repair time of the waterproof floor Since the repair site can be easily determined visually, the time and cost required for repair can be reduced.

It is a sectional side view which shows the abrasion state of a waterproof floor, Comprising: (a) is a figure before exposure of a colored layer, (b) is a figure at the time of exposure of a colored layer. It is the figure which looked at FIG.2 (b) from the top, Comprising: It is a figure which shows an example of the exposure state of a colored layer. It is a sectional side view which shows a part of 1st waterproof floor by a modification. It is a sectional side view which shows a part of 2nd waterproof floor by a modification. It is a sectional side view which shows a part of 3rd waterproof floor by a modification.

Hereinafter, a waterproof floor structure provided with a maintenance sign according to an embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the waterproof floor structure provided with the maintenance sign according to the present embodiment is applied to the waterproof floor 1 constructed on the concrete slab R of the rooftop parking lot, and the repair timing of the waterproof floor 1 is as follows. This is a structure for suitably judging.
Here, in the present embodiment, in the thickness direction of the waterproof floor 1, the upper side is referred to as the front side, and the lower side is referred to as the back side.

The waterproof floor 1 has a laminated structure having a waterproof layer 2 provided on the slab R, an anti-slip layer 3 provided on the upper layer of the waterproof layer 2, and a top coat layer 4 that protects the surface of the anti-slip layer 3. Yes. The anti-slip layer 3 has a colored layer 5 formed in a layer shape in the middle in the thickness direction of the anti-slip layer 3 and formed in a layer shape with a color different from other parts of the laminated structure. doing. Each of these layers is formed by applying each material sequentially from the lower layer by spraying or the like.
Note that FIG. 1 is a diagram in which steps are provided between layers for easy viewing.

  The waterproof layer 2 is made of a general waterproof resin material of urethane resin type, and is provided on the primer layer 6 applied to the surface of the slab R.

  The anti-slip layer 3 includes a plurality of layers (here, seven non-colored layers 3A to 3F and the colored layer 5), and the colored layer 5 is provided in the middle in the thickness direction. That is, three layers are provided above and below the colored layer 5, respectively. The anti-slip layer 3 is made of a general urethane resin waterproof resin material different from the material of the waterproof layer 2, and an anti-slip material mixed with an anti-slip material such as an aggregate is used.

  The colored layer 5 is provided by mixing colored toner of any color with the urethane resin type anti-slip material forming the anti-slip layer 3 described above. Further, the present invention is not limited to those in which a colored toner is mixed, and a thin colored layer 5 may be inserted between a plurality of layers of the anti-slip layer 3.

  And as for the color of the colored layer 5, when the color of the other layer of the waterproof floor 1 is gray, green (green) which is hard to discolor is preferable. For example, when the colored layer 5 is yellow, it is easily discolored by ultraviolet rays, and is difficult to distinguish from the color of other layers (here, gray). In addition, when the colored layer 5 is green, the discoloration is small even after about half a year from the exposure, and it is experimentally confirmed that the color difference from the gray color of other layers is clear. ing.

Next, the effect | action of the waterproof floor structure provided with the maintenance sign mentioned above and its construction method are demonstrated in detail based on drawing.
As shown in FIG. 1, the waterproof floor 1 of the present embodiment is further provided with a waterproof layer 2 after the primer layer 6 is applied on the slab R of the rooftop parking lot, and the anti-slip layer 3 is provided above the waterproof layer 2. In addition, the colored layer 5 formed in a layer shape in a green color different from the gray color of the other part of the laminated structure is provided in the middle portion of the anti-slip layer 3, and then the surface of the anti-slip layer 3 is covered with the top coat layer 4 It can be formed by coating.

In this case, as shown in FIGS. 2 (a), 2 (b) and 3, the colored layer when the layer above the colored layer 5 in the laminated structure constituting the waterproof floor 1 is worn due to traveling of an automobile or the like. 5 is exposed. The code | symbol M shown in FIG. 2 has shown the wear part. And since the color of the colored layer 5 and the other part (non-colored layers 3D to 3F above the colored layer 5 in the anti-slip layer 3) of the laminated structure is different, the colored layer 5 exposed by wear is replaced with the other layer. It becomes easy to discriminate against other color portions. That is, by providing the colored layer 5 having a color different from that of the other parts of the laminated structure on a part of the anti-slip layer 3 on the upper layer of the waterproof layer 2, the colored layer can be used in accordance with the use frequency and usage situation of the rooftop parking lot. When the layer above 5 is peeled off due to abrasion, the colored layer 5 is exposed on the surface side, and the exposed portion of the colored layer 5 becomes a portion whose color has changed on the waterproof floor 1. And since the colored layer 5 is arrange | positioned rather than the waterproof layer 2, the waterproof layer 2 will not be abraded in the state which the colored layer 5 exposed. Therefore, the colored layer 5 serves as a maintenance sign for determining the repair site and the repair time when a portion where the color has changed (an exposed portion of the colored layer 5) appears.
Therefore, in order to confirm the repair site and the repair time, the exposed maintenance sign can be easily confirmed visually, even if it is not an administrator who has technical knowledge as in the past.

  More specifically, only the portion of the colored layer 5 where the colored layer 5 is exposed on the surface of the waterproof floor 1 is confirmed by daily inspection, and the waterproof floor 1 damaged by abrasion is periodically repaired. In this case, since the waterproof layer can be repaired before it is worn and only the repair of the anti-slip layer 3 (colored layer 5) and the top coat layer 4 is required, the entire waterproofing material including the waterproof layer 2 is covered. Costly maintenance of renewal becomes unnecessary, and the life cycle cost can be reduced.

  Further, in the present embodiment, the colored layer 5 can be easily formed by mixing the color toner in the anti-slip material and applying it by spraying or the like. Even when the anti-slip layer 3 is formed of a plurality of layers, the colored layer 5 can be provided at an arbitrary position of the plurality of layers.

  In addition, since the colored layer 5 is present in the middle in the thickness direction of the anti-slip layer 3, if the upper layer portion of the anti-slip layer 3 is damaged by abrasion, the colored layer 5 appears and serves as a maintenance sign. Further, even if the colored layer 5 is worn and damaged, the anti-slip layer 3 (non-colored layers 3A to 3C) is further provided below the colored layer 5, so that the influence of wear on the waterproof layer 2 can be reduced. it can.

In waterproof floor structure with a maintenance sign according to the present embodiment as described above, together with the waterproof layer 2 it is possible to suppress the repair of the waterproof layer 2 by checking the repair time before damage by abrasion Since the repair timing and repair site of the waterproof floor 1 can be easily determined by visual observation, the time and cost required for repair can be reduced.

Having described embodiments of a waterproof floor structure with a maintenance sign according to the invention, the invention is not intended to be limited to the above embodiments, and can be suitably changed without departing from the scope thereof .

  For example, in the present embodiment, the colored layer 5 is a part of the anti-slip layer 3 and is provided in an intermediate portion in the thickness direction of the anti-slip layer 3, but is limited to such a position. There is nothing. Moreover, in the waterproof floor 1 of this Embodiment, although it has the same laminated structure over the whole roof parking lot, it is not limited to this. In short, it is sufficient that at least a part of the anti-slip layer 3 has a colored layer formed in a layer shape with a different color from the other layers.

  For example, as shown in FIGS. 4 to 6, the number of the anti-slip layers 3 is changed depending on the usage of the rooftop parking lot or the running situation (running frequency) of the automobile, and the colored layer in the running range of the automobile in the rooftop parking lot. It is also possible to set the thickness dimension above 5 to be thicker than other parts. FIG. 4 shows the first waterproof floor 1A in the parking space in the rooftop parking lot. The first waterproof floor 1 </ b> A has only one anti-slip layer 3, and the entire anti-slip layer 3 is a colored layer 5. In this case, since the colored layer 5 is located on the lower surface side of the topcoat layer 4, when the topcoat layer 4 is shaved due to wear, the antiskid layer 3, that is, the green colored layer 5 is exposed immediately.

Here, two types of roadways are provided in the rooftop parking lot.
FIG. 5 shows the second waterproof floor 1B in the first roadway in the rooftop parking lot. The second waterproof floor 1B has two anti-slip layers 3, and only the lower layer of the two anti-slip layers 3 is a colored layer 5 and the upper layer is a non-colored layer 3A. Yes. In this case, since one non-colored (gray in this case) non-colored layer 3A is located on the lower surface side of the top coat layer 4, when the top coat layer 4 and the non-colored layer 3A are scraped off due to wear, The colored layer 5 is exposed.

  FIG. 6 shows the third waterproof floor 1C in the second road in the rooftop parking lot. The third waterproof floor 1C has three anti-slip layers 3, and only the bottom layer of the three anti-slip layers 3 is a colored layer 5 and the upper two layers are non-colored layers 3A and 3B. It has become. In this case, since the two non-colored (in this case, gray) non-colored layers 3A and 3B are located on the lower surface side of the top coat layer 4, the top coat layer 4 and the non-colored layers 3A and 3B are scraped off due to wear. In addition, the green colored layer 5 is exposed.

Thus, in the rooftop parking lot, the roadway (first roadway, second roadway) that is the traveling part of the automobile that is damaged by abrasion of the waterproof floor 1 is more colored than the parking space (other parts). Since the thickness dimension on 5 is formed thick, the period until the maintenance sign in which the colored layer appears can be extended.
Further, in the case of the waterproof floors 1A to 1C shown in FIGS. 4 to 6, since the waterproof layer 2 is located immediately below the colored layer 5, the repair is promptly performed when the colored layer 5 appears. It can be confirmed that it is time.

  In the present embodiment, the color of the colored layer 5 is green, which has the least color change, and the color of the other layers other than the colored layer 5 is gray. It is not limited to this, and any combination of colors can be set. In short, it is only necessary that the color of the colored layer is little discolored and the color difference from other parts is clear.

  Furthermore, in the present embodiment, only one colored layer 5 is interposed in the anti-slip layer 3, but a plurality of colored layers 5 can also be disposed. And you may make it change the color of the some colored layer 5 respectively. For example, it can be set as the structure which distribute | arranges the 1st colored layer in the intermediate part of the thickness direction of the anti-slip layer 3, and arrange | positions the 2nd colored layer of the color different from a 1st colored layer in the lowest layer. Or the structure which laminated | stacked the several colored layer from which each color differs continuously up and down may be sufficient. By providing a plurality of colored layers in this way, for example, when the upper colored layer appears, it is confirmed that it is in the initial stage of wear, and when the lower colored layer appears, it is confirmed that it is the repair timing. Thus, the wear state of the waterproof floor can be determined in stages.

  In addition, it is possible to appropriately replace the components in the above-described embodiments with known components without departing from the spirit of the present invention.
