Abstract

PROBLEM TO BE SOLVED: To easily execute a nonslip treatment by putting a form member on the surface of a paved road having an inorganic hard surface, applying a resin mixed with an additive which bonds to both inorganic substances and organic substances on the upper side to form a joint-like pattern or the like, and removing the form member. SOLUTION: A form member 2 is put on the surface of a paved road 1 formed of terrazzo blocks and a coating resin 3 is applied on the other parts except the form member. After the resin 3 has hardened, the form member 2 is removed. As the resin 3, an ordinary resin such as urethane-based, epoxy- based, acrylic based, and fluorine-based resin, etc., are used. An additive which bonds to both inorganic substances and organic substances is mixed with the resin 3. A frictional coefficient of the applied surface gets larger due to the thickness by partially applying the special resin 3 on the hard paved road. Accordingly, a nonslip treatment can be easily applied on an existing paved road without use of large equipment.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pavement surface treatment method. The pavement here means not only general paved roads (roadways and sidewalks), but also shopping streets, stations,
It refers to all places where humans walk on the floor, such as department stores, stairs, and porches.

[0002]

2. Description of the Related Art Pavement surface treatment is originally intended to smooth the surface (smoothing here means that there is no hollow like a road) and to stabilize (not to be muddy). It is made to be convenient for operation of automobiles and the like. Road pavement is a typical example. This surface treatment is not simply required to be smooth, but is used under very severe conditions such as roads and the like, so that high weather resistance and durability are required. Therefore, roads and the like have been paved with concrete, asphalt, brick, stone, and the like.

[0003] Further, as the times progress, not only the smoothness but also the aesthetic appearance is required. In particular, a paved road in an arcade or a floor surface of a department store has a strong feeling. Therefore, stone has conventionally been used as a material having three of smoothness, durability and aesthetic appearance. That is, it is a method of laying a thin slice of natural stone (marble, granite, or the like). Also, natural stones are expensive,
Pebbles (crushed natural gravel or natural stones) were hardened with cement or the like, sliced in the same manner, molded into a flat plate and polished on the surface (terrazzo plate), laid down, and furthermore, the material was finished on the spot with a clerical finish Later, there is a method of polishing by a so-called "field sharpening method" (also referred to as a terrazzo plate here). The pavement under the arcade, the floor of a department store, and the like are very often of this type.

[0004]

As described above, stone is very often used as a surface material of a pavement. The surface of the stone is often polished to enhance the beauty of the stone. This is because if not polished, there is no luster peculiar to natural stone, and it is easily stained during operation, and there is no aesthetic sense using expensive natural stone. For this reason, the surface becomes very smooth (the smoothness here is a microscopic smoothness and means smooth), and a human, a car, a bicycle or the like easily slips, which is very dangerous.

[0005] In order to reduce such danger, slip is prevented by laying a cutout on a part of the surface or a stone plate provided with irregularities. However, the stone itself has a very long life and can be used for 10 to 50 years. When used for such a long period of time, even a hard object such as a stone, the surface is smoothed during use, and the danger of slipping occurs again. In fact, accidents due to this slip have been occurring frequently in recent years, sometimes leading to damages.

[0006] Furthermore, stones and terrazzo plates, etc., which can withstand long-term use, often get tired of their colors and patterns, and especially in department stores and arcades, there are many demands for refurbishment (or refurbishment). . In such a case,
Whether to prevent slippage or to retrofit a pattern or the like, all the old stones and terrazzo plates are removed and new stones and terrazzo plates are laid.

This conventional method has the following problems. It takes a very long time to remove stones and to stick new stones, terrazzo plates, etc. with cement or the like. If the construction period is long, stores and the like suffer business damage over a long period of time, and also cause traffic obstacles to pedestrians and the like. High construction cost. Still, enough usable stones must be discarded, which is a waste of resources. A large amount of waste comes out and is designated as industrial waste, which affects its disposal. The roadside environment such as noise, vibration, dust, etc. caused by construction is impeded. Accordingly, there has been a long-felt need in the art and the like for a surface treatment method for pavement or the like that does not have the above-mentioned disadvantages.

[0008]

In view of the above situation, the present inventors have made intensive studies and completed the surface treatment method of the present invention. A mold member is placed on the surface of a pavement with a resin, and a resin containing an additive that binds to both inorganic and organic substances is mixed from above the joint, tiles and other joints, mosaics, animal and plant figures, character figures, etc. The point is that the mold member is removed after being applied in the pattern of the pattern.

[0009] The pavement having an inorganic hard surface is a pavement having a very hard surface, such as a natural stone sliced and pasted (laid), a terrazzo plate, a washed concrete plate, or the like. Or high hardness or high hardness. Among them, those in which natural stone is entirely or partially exposed on the surface are preferable.

[0010] The mold member covers a portion not to be coated when the coating material is applied, and is usually a flat plate that is partially punched, such as a so-called template.
However, it may be in a tape shape (stick joint, roll shape, etc.). For those with punched parts, depending on the shape,
Joints such as tiles, mosaics, figures of animals and plants, character figures, etc. can be expressed.

As the material, paper and plastic are preferable. When the coating material is applied thickly, rubber, foamed polyethylene, foamed polypropylene, or the like is preferable. The thickness is determined by the coating thickness, but is usually about 0.1 to 1.0 mm.
Also, the size of the mold member is not particularly limited,
For convenience of handling, the size is preferably about 1 m × 1 m. Also,
For long pavements and the like, it is convenient to use a continuous long one wound in a roll.

The mold member is adhered to the surface of the pavement with an adhesive. However, since it is troublesome to apply the adhesive while laying the adhesive, the adhesive is applied to the back surface, and the mold is peeled off. It is convenient to use a piece of paper stuck on the pavement surface while peeling off the release paper at the site. However, when the mold member is reused, the adhesive is again applied to the back surface of the mold member with a roller or the like,
This may be done on site or again at the factory.
In the case of a mold member having a large number of punched portions or a large punched area, it is also preferable from the viewpoint of handling that a backing sheet having no punched portion on the back surface is subjected to a peeling treatment and adhered.

[0013] A thin film of the same shape on the upper surface of the mold member may be attached. In this method, after the application material is applied, it is removed before curing. It is removed before curing to prevent the coating material from curing on the mold member. Of course, the mold member body is removed after curing.

[0014] The placing means that a mold member is laid on the surface of the pavement.
Adhere the back side with an adhesive. This adhesive may be of any kind, but preferably does not remain on the pavement surface after peeling.

The resin used as the coating material may be a usual resin such as urethane, epoxy, acrylic and fluorine. Colors can be freely set by mixing pigments and the like. Further, when the hard material to be applied has a beautiful pattern or color and it is regrettable that the hard material is partially invisible at all, a transparent resin may be used.

It is necessary to add an additive which binds to both inorganic and organic substances to the resin. This is a compound that has both a reactive group that binds to an inorganic substance and a reactive group that binds to an organic substance in the molecule, and a mixture of a compound that binds to an inorganic substance and a compound that binds to an organic substance, and they adhere well. Or any substance that inherently binds well to inorganic and organic substances. As the additive that binds to both the inorganic substance and the organic substance, a silane coupling agent or the like is already commercially available, and such an additive may be used.

The term "pattern" means that the resin is not applied on one surface or applied at random, but is applied so as to form a predetermined pattern. The predetermined pattern is, for example, joints such as tiles, mosaic, animal and plant figures, character figures, etc.
Any pattern such as a checkered pattern or a polka dot pattern may be used.

However, since the first object of the present invention is to prevent slippage, accumulation of water on the surface is desired to be reduced as much as possible. Because the resin surface has water repellency and thickness,
If there is a way for water to escape, water will be drained quickly. For this purpose, the above-mentioned pattern (the portion where the resin is not applied, that is, the portion covered with the mold member) is connected to the periphery and may constitute a drain groove.

According to the present invention, a special resin is partially applied to a hard pavement, and by applying the resin partially, the friction coefficient is increased by the resistance due to its thickness.
Therefore, if the applied portion is too large, the frictional resistance value may be small with only the resin layer. Therefore, in the resin of the present invention,
Inorganic aggregates may be mixed. For example, glass beads, crushed materials such as glass, ceramics, stones, and the like. As for the size, it is preferable that the size is larger than the applied thickness of the resin and that the texture is rough due to the presence of the aggregate. For example, when the coating thickness is about 0.3 mm, the friction coefficient is remarkably improved when an aggregate of 0.5 to 1.0 mm is mixed.

The method of applying the resin is arbitrary, and may be roller coating, brush coating, or the like. The mold member is removed after the resin is cured, but may be removed before curing if the coating thickness is thin and there is no problem of dripping.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail with reference to the embodiments shown in the drawings. FIG. 1 is an end view showing the steps of the method of the present invention. (A) shows the place where the mold member 2 is placed on the surface of the pavement 1 made of a terrazzo plate. Thickness is not to scale. (B) is a state where the coating material resin 3 is applied to a portion other than the mold member. After the resin 3 is cured, the mold member 2 is removed (c). This is the end.

FIG. 2 shows a state where the resin 3 is applied to the terrazzo plate 1 and the mold member 2 is removed. It can be seen that the portion 4 where the resin 3 is not applied forms a groove and promotes the discharge of water. That is, the water on the resin surface falls into the grooves due to the high water repellency of the resin, flows from there to the surroundings, and finally to the side grooves.

FIG. 3 shows a resin 3 mixed with an aggregate 5. It can be seen that large irregularities are formed on the surface, and the frictional resistance value is extremely large.

FIG. 4 is a view similar to FIG. 1, but using a double structure as a mold member. That is, the film 7 is attached to the upper surface of the main body 6 of the mold member 2. The main mold member is placed on the surface of the hard pavement material 1 (FIG. 4A), and the resin 3 is applied thereon (FIG. 4B). At this time, FIG.
As can be seen from (b), the resin 3 is inevitably applied to the upper surface of the mold member 2. If the resin 3 is cured as it is, it becomes difficult to remove the mold member 2 or even if it can be removed, it cannot be removed neatly according to the shape of the mold member. Further, if all the mold members are removed during the uncuring, the uncured resin spreads right and left and does not become a sharp shape.

Therefore, only the thin film 7 on the upper surface is removed while the resin 3 is not yet cured (FIG. 4C). Since it is the time of uncured, removal is easy and it can be removed cleanly. And
Since the main body is left until the resin is cured, the uncured resin does not spread right and left. After the resin has hardened, the main body may be removed (FIG. 4D).

[0026]

According to the method of the present invention, there are the following significant advantages. Slip prevention can be easily performed on an existing pavement without using a large device. You can change the pattern of the pavement you are tired of at the same time. Very cheap. Probably, it is 1/3 to 1/5 compared with the replacement of natural stone. The construction period is very short, and is greatly reduced compared to the conventional method using cement or mortar. As a result, the business hindrance period of stores etc. is greatly reduced,
There are very economic benefits. The resources that can still be used are not wasted and resources are saved. This is consistent with the national policy of resource saving. Waste treatment is reduced because industrial waste is reduced. It is useful for preventing traffic obstacles to general traffic vehicles and pedestrians and deterioration of roadside environment during construction.
