Description

Description: TECHNICAL FIELD The present invention relates to a surface treatment device for a pavement or the like.

[Prior Art] The pavement and the like referred to here include not only general pavements such as roads (especially heavy roads), expressways and roads in tunnels, but also roads and other grounds having a somewhat smooth surface, such as gardens, It is used as a concept that includes parks and courtyards in structures.

Since pavements, especially sidewalks having roofs and arcades, are used as shopping streets and courtyards, their aesthetics are important. For this reason, various surface treatments are performed in addition to the pavement like a normal road. This is also being demanded on roads and the like.

There is also a demand for a surface treatment that is more durable than ordinary pavement.

As an aesthetically pleasing and durable surface treatment method, there are also a tiling method in which tiles are laid in a mosaic form, a stone bonding method in which a natural stone plate is laid, and a method in which a synthetic resin plate is laid. .

[Problems to be Solved by the Invention] However, the method of laying tiles and stones requires bonding one by one at the site, which is a very laborious operation.

In addition, there is also a disadvantage that the construction period is not constant due to the weather and the temperature because the mortar is used for bonding. further,
Some skill was required, and the cost had to be high.

In the above-mentioned method, in order to satisfy a demand for expressing a fine pattern or changing colors in small units, the size of tiles to be laid must be reduced, which requires more time and effort. However, recently, there has been a tendency to favor such patterns studded with fine stones.

Of course, because it is used as a road, weather resistance,
Needless to say, wear resistance and the like are required.

Therefore, the present applicant has developed a surface treatment method that is easy to perform on-site, does not require skill, and has an aesthetic appearance in which fine patterns and fine stones are studded, and has applied for a patent. In this method, an adhesive is laid on the surface of a pavement or the like, and a granular material is adhered to the adhesive with no gap by utilizing the adhesive force of the adhesive, and then coated with a synthetic resin.

The present invention aims at improving efficiency and reducing labor costs when implementing the basic invention, and is an apparatus capable of continuously performing the steps of the basic invention at once.

[Means for Solving the Problems] A feature of the present invention is that a vehicle for treating a pavement or the like is provided with a pressure-sensitive adhesive sheet holder, a granular material holding container having a granular material discharge port, and a granular material suction port in order from the traveling direction. The present invention is characterized in that a particulate suction device, a pressing roller, and a resin coating device having the following are provided.

Here, an automobile for processing a pavement or the like refers to an automobile that runs on a pavement or the like and treats the surface thereof.

The pressure-sensitive adhesive sheet may be a plastic sheet to which a heat-adhesive has been applied, or may be a sheet having adhesive strength itself. The pressure-sensitive adhesive refers to a substance that can maintain the adhesive force for a long period of time, and is preferably a rubber-like substance. As the sheet having an adhesive force, a commercially available non-vulcanized butyl rubber sheet, and a sheet in which a net or a thread is sandwiched between the sheets to increase the tensile strength are preferable.

In both cases, if the back surface has no adhesive force (adhesive force), it is desirable to apply an adhesive to the back surface. This is to prevent slippage when laying on a pavement or the like. In the case where the back surface of the sheet-shaped material has an adhesive strength, it is preferable that a release paper is adhered to the back surface for handling.

This adhesive force allows the granular material to be placed on the adhesive and
When removing the excess, it is only necessary to have a fixing force enough to adhere to the extent that the necessary particulate matter is not removed at the same time, and it is not necessary to completely fix and fix the stone so that the resin hardens.

The shape of this adhesive sheet may be any,
A long sheet is suitable so that continuous laying on a pavement is easy.

The laying thickness of the adhesive is not particularly limited, and may be appropriately selected depending on the size of the granular material, the adhesive strength, and the like.
Usually, about 0.5 to 3.0 mm is sufficient.

The holder is a device that holds the pressure-sensitive adhesive sheet and sequentially feeds the pressure-sensitive adhesive sheet. When the pressure-sensitive adhesive sheet is a long continuous body, it is preferable to hold the pressure-sensitive adhesive sheet by rolling it. In this case, the holding tool is simply a roll, and the feeding may be automatically performed by running the automobile, or a motor may be separately provided and controlled automatically or manually. When a release paper is attached to the adhesive sheet, a roller for winding and removing the release paper is provided.

Further, when the pressure-sensitive adhesive sheet is not a continuous body but is a plate-like sheet, any sheet may be used as long as the sheet is dropped one by one. What is necessary is just to drop the laminated plate-shaped sheet with an extruder.

Granular material refers to the shape and size of a pebble (2 to 10
mm). Of course, it may be somewhat flat or long. A typical example of this granular material is natural stone. Natural stones may be placed in various colors at random, or may be fixed colors. Further, a pattern may be made to appear only in a specific portion by using a stone of a specific color by using a pattern described later.

As the granular material, not only natural stone, but also a ceramic mixed with a pigment and fired, or a ceramic colored material may be used.

The granular material holding container is a container for storing the granular material, and may have any shape. The container is provided with a granular material discharge port. This outlet is
In this method, the granular material is adhered to the pressure-sensitive adhesive sheet without gaps. Adhering without gaps means that there is no exposed part of the adhesive on the sheet, but it is theoretically impossible to have no exposed part at all, so it is about the whole area. Meaning. Substantially the entire area means that there is almost no exposed part where a stone of the same size as the attached stone can enter. For such attachment, the width of the discharge port is preferably larger than the width of the sheet, the length is small, and a horizontally long rectangular shape is preferable.

The granular material may be dropped only by gravity, but may be sent out by a simple conveyor.

As for the method of placing (adhering) the granular material, there is also a method of carefully placing the granular material corresponding to the area of the pressure-sensitive adhesive layer on the pressure-sensitive adhesive sequentially, but excessively applying the granular material to the pressure-sensitive adhesive layer. The method of mounting and removing the excess (the amount not fixed by the adhesive) is simple.

For this removal, a method of sucking with a granular material suction device such as a vacuum pump is convenient and simple. In addition, the suctioned granular material can be introduced into the above-described granular material holding container for reuse.

The suction port of this suction device is like a normal vacuum cleaner and does not need to have a special shape, but needs to be wider than the adhesive sheet. The suction force is smaller than the force that the granular material is attached by the adhesive sheet,
What is necessary is just to be able to suck up the particulate matter.

In order to adhere the granular material more precisely and smoothly between the granular material discharge port and the suction port, a hammer-like or flat-plate-like leveling tool may be provided. The leveling tool may be used while being moved by a motor or the like so that the granular material can be placed on the entire area.

The pressing roller is for placing (adhering) the granular material on the adhesive sheet more smoothly, and may be a normal roller for pavement construction. This roller not only serves to smooth a large number of particles, but also serves to press and partially drive the particles against the adhesive layer. Particularly, in the case of a stone having a somewhat sharp shape downward, the stone is driven into a wedge-like shape, thereby preventing the stone from separating. When the size of the stones is large or small, the large stones are pressed mainly to have a wedge effect and smooth the surface. By these,
It can be used on roads, especially on heavy roads. This is further ensured by the application of a resin described below.

The resin coating device is a device for coating a resin, and may be any type such as a spray type, a brush coating type, and a roller coating type. This device is for firmly attaching the granular material to the lower adhesive layer, and covers the granular material with a resin, that is, coats with a synthetic resin.

As an example of the synthetic resin, an acrylic resin or an epoxy resin is preferable. This synthetic resin is usually transparent to see the color of natural stone, but may be colored by mixing a pigment. In particular, expressing a pattern with a part of it being colored will bring out another aesthetic appearance. Fast drying materials are preferred.

A device capable of puffing may be provided behind the resin application device to polish the resin surface.

Further, as another aspect of the present invention, in order to cope with a method of directly applying an adhesive to a pavement or the like without using an adhesive sheet, instead of the adhesive sheet holder, an adhesive application device may be installed. . This may be the same as the resin coating device described above. The adhesive does not need to be special, and a commercially available adhesive is sufficient. That is, the final fixation of the granular material is performed by the resin coating in the subsequent resin application step.
