Description

Description: TECHNICAL FIELD The present invention relates to a color pavement construction method for applying a color pattern to the surface of a pavement such as a sidewalk, a roadway, and a plaza.

(Prior Art) Conventionally, a pavement portion such as a sidewalk, a roadway, or a plaza in a park (hereinafter referred to as a pavement body) has been simply piling asphalt or concrete. Therefore, slips have been prevented by providing grooves on the surface of the pavement or mixing coarse aggregate such as split stone into asphalt or concrete.

By the way, in recent years, in order to cope with the diversified urban environment and sports environment, the surface of the pavement is coated on the surface of the pavement with a method of spraying silica sand or ceramic sand and hardening with a resin (neat method). A so-called color pavement method for applying a color pattern is becoming popular.

(Problems to be Solved by the Invention) However, in such a conventional color pavement method,
There is a problem that it is difficult to create a complicated pattern pattern or a three-dimensional uneven pattern on the surface of the pavement body, and it is not possible to meet the needs of the times. There is also a problem that the slip effect is reduced by applying a color pattern to the surface of the pavement.

The present invention has been made in view of such circumstances, particularly colorization and slip prevention of the pavement surface can be achieved without breaking the pavement body such as old asphalt and concrete, and the same as when using tiles or the like. It is an object to provide a color pavement construction method capable of producing a three-dimensional effect and a decorative effect. Another object of the present invention is to provide a color pavement construction method that enables color pavement to be performed more easily by allowing the formwork member to be in close contact with the surface of the first pavement.

(Means for Solving Problems) The color pavement method of the present invention is applied to a surface of a pavement such as a road or floor on which asphalt or concrete has been cast, after applying a first pavement material containing a pigment, On the surface of the first pavement material, the inside is partitioned into an arbitrary pattern shape, and a cushion member is attached to the back surface of the first pavement material, or a formwork member coated with an adhesive agent is installed. After the formwork member is brought into close contact with the surface of the first pavement body, a second pavement material containing a pigment is applied to the inside of the formwork member for curing and curing, and then the formwork member is removed. An uneven pattern is formed on the surface of the pavement by the first pavement material and the second pavement material.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an example of a form member used in the color pavement construction method of the present invention.

The mold member 1 shown in the figure is of a type that is repeatedly used and is used when forming a thick uneven pattern.

The form member 1 has a pattern substrate 2 whose inside is partitioned by a partition member 2a into a grid pattern, a cushion material 3 attached to the lower surface of the pattern substrate 2, and three edges of the periphery of the pattern substrate 2. The outer frame member 4 is erected so as to surround it. One edge of the pattern substrate 2 is left open because the paving material applied to the pattern substrate 2 (the paving material will be described later).
This is because the extra pavement material protruding from the patterned substrate 2 is taken out from here.

The material for forming the patterned substrate 2 may be metal, resin, cardboard subjected to water repellent treatment, or the like, which is dimensionally stable against changes in temperature and has excellent water resistance. The patterned substrate 2 can be produced by various methods, but punching with a press machine is suitable for mass production and economical. Also, the pattern substrate 2
The size and thickness of the product vary depending on the design and how to create the uneven pattern, but if too large, problems will occur in terms of weight and handling, so select an appropriate size (eg 600 x 600 mm).

The cushion material 3 is provided to bring the pattern substrate 2 into close contact with the uneven portion of the underlying pavement surface, and is punched by the same press machine that punched the pattern substrate 2. As a material for forming the cushion material 3, a flexible rubber material (acrylic urethane, natural rubber or the like), or a polyethylene resin or a vinyl chloride resin to which flexibility is given by foaming is preferable.

The outer frame member 4 serves to prevent the paving material applied to the pattern substrate 2 from spilling to the outside.
It is fixed to the pattern substrate 2 by adhering to the peripheral edge of the pattern substrate 2 with an adhesive or by being fitted on the pattern substrate 2. The thickness of the outer frame member 4 is formed to be equal to the thickness of the partition member 2a that partitions the pattern substrate 2 into a grid pattern. As a material for forming the outer frame member 4, metal, wood,
Plastic or the like is suitable, and one that is lightweight and difficult to deform is used. The size of the pattern substrate 2 and the partition member 2a
The number of cells divided by is as shown in Fig. 2 (a), (b),
As shown in (c), the design may be changed appropriately according to the use and location.

FIG. 3 shows another example of the form member.

The mold member 11 shown in the figure is of a disposable type and is used when forming an uneven pattern having a small thickness.

The frame member 11 is a pattern sheet base material 12 formed in a predetermined square or rectangular shape and the inside of which is partitioned into an arbitrary pattern shape, and an adhesive 13 applied to the lower surface of the pattern sheet base material 12. The release paper 14 is temporarily adhered to the adhesive 13. Further, FIG. 4 shows the form member 21 having such a structure in the form of a scroll instead of a square.

Polyvinyl chloride (PVC), polyethylene (PE), polypropylene (P
P), synthetic resin such as ethylene-vinyl-acetate copolymer (EVA), metal such as aluminum foil, water-repellent treated paper, etc. are suitable, and have little expansion and contraction due to temperature and have appropriate tensile strength. Anything is fine. If a certain thickness is required, expanded synthetic resins such as polystyrene (PS), polyethylene (PE) and polypropylene (PP) are suitable.

Next, the color pavement construction method of the present invention using each of the above-mentioned formwork members will be described in the order of steps.

Cleaning the pavement First, remove impurities such as dust and oil stains on the pavement surface,
Dry if water is present. Also, in the case of new concrete paving, etc., leitance should be removed.

Primer application For the primer, use a dedicated primer for concrete, asphalt, etc., and apply it on the surface of the pavement with a roller, brush, sponge, etc.

Undercoat After the primer has dried, the first pavement material is applied. As the coating method, trowel coating, brush coating, roller coating, spray coating or the like is appropriately selected depending on the thickness to be coated.

The composition material of the first pavement material is a one-component acrylic resin-based, acrylic urethane resin-based resin material of a type that cures by evaporation of water or a solvent, or two-component epoxy resin, urethane resin, MMA resin. A reaction-curing type resin material such as the above is used, and an aggregate having excellent wear resistance (for example, silica sand or ceramic sand) and a color pigment are dispersed and mixed in any one of the resin materials.

After the undercoat is dried, in order to clarify the position of the mold frame member, a marking line is drawn according to the shape and size of the mold frame member, and dimensioning is performed so that the pattern shift and the pattern allocation are not biased.

Formwork installation Formwork members prepared in advance according to the construction space will be installed along the marking lines.

At this time, when the mold member 1 having the shape shown in FIGS. 1 and 2 (a) to (c) is used, the pattern substrate 2 is used.
Also, a mold release material is applied to each inner wall surface of the cushion material 3. When using the mold members 11 and 21 having the shapes shown in FIG. 3 and FIG. 4 described above, after confirming the hardening of the first paving material, the release paper 14 is peeled off and stuck along the marking line. Go on. In this case, since the cushion material 3 and the adhesive 13 are provided on the back surfaces of the form members 1, 11 and 21, even if the surface of the first paving material has slight irregularities, the cushion material 3 or the adhesive 13 is formed. As a result, the irregularities are absorbed, and a gap is not formed between the formwork members 1, 11, 21 and the first pavement material, and they are in close contact. Further, since the form member can be installed and constructed in a state where the first pavement material is hardened or dried and has no adhesive force, it is possible to perform work without noticing the coating state of the first pavement material. it can.

After that, the second paving material is applied from above the form members 1, 11, 21 by roller coating, brush coating, spray coating, or the like. The composition material of this second paving material is
It is similar to the composition material of the pavement material. However, a more colorful pattern can be obtained by appropriately changing the color pigments to be mixed.

After curing and curing the second pavement material, the formwork members 1, 11, 21 are removed to form an uneven pattern of the first pavement material and the second pavement material on the surface of the pavement.

If necessary, in order to improve wear resistance, stain resistance, and weather resistance, a transparent clear coating (for example, acrylic urethane resin) is sprayed or rollers on the surfaces of the first pavement material and the second pavement material. Apply with a brush.

FIG. 5 shows a sectional view of the concavo-convex pattern formed by each of the above steps. In the figure, reference numeral 30 is a painted body, reference numeral
Reference numeral 31 is the first pavement material, and reference numeral 32 is the second pavement material.

In the case where the mold member 1 is used in the above step and an acrylic emulsion having a long curing time is used as the second paving material in the next step, as shown in FIG. , The frame members 1 are alternately installed every other frame separated by marking lines (positions indicated by reference symbol a in the figure) to perform overcoating, and after curing, the form member 1 is provided between them (reference symbol in the figure) Alternatively, the upper coating may be performed again at the position indicated by b). Further, in the above step, glass beads may be scattered on the surface of the second pavement material immediately after the overcoating to reflect light such as light at night.

The present inventors conducted a slip resistance test in order to confirm the effect of preventing slip due to the uneven pattern formed by the above method. The results are shown in the table below.

From these results, it was confirmed that when the surface of the pavement was provided with a concavo-convex pattern by the color pavement method of the present invention, the slip resistance was larger than that during asphalt pavement or concrete pavement, both when dry and when wet.

The above-mentioned color pavement construction method is a construction method that simultaneously achieves a color pattern finish and an anti-slip effect, but it is generally used for various regulatory signs (such as parking prohibition and bicycle marks, etc.) drawn with hot melt type traffic paint. ) Is also applicable.

(Effect of the Invention) According to the color pavement construction method of the present invention, the following excellent effects are exhibited.

A frame member having an interior partitioned into an arbitrary pattern and having a cushion material adhered or an adhesive applied to the back surface thereof is installed on the first pavement body, and the cushion member or the adhesive is used to separate the frame member. Since it is configured so as to be in close contact with the surface of the pavement 1, even if there is a slight unevenness on the surface of the first pavement material, the unevenness is absorbed by the cushion material or the adhesive, and the formwork member and the first pavement material are There is no gap between
Because of the close contact, the second pavement will not ooze out from the formwork member during subsequent application of the second pavement.

Since the form member can be installed and constructed in a state where the first pavement material is hardened or dried and has no adhesive force,
The work can be performed without worrying about the application state of the first paving material, and the workability is also improved.

In the field construction, it is possible to form an uneven color pattern on the surface of the pavement without destroying the pavement such as an old road or floor.

The uneven pattern can prevent slip.

Unlike using tiles and bricks, you can freely select colors and uneven patterns, and there is no restriction on size and shape as when using tiles and bricks, and large patterns. Also, it can be easily formed seamlessly. Therefore, it is possible to easily create a complicated picture pattern or a three-dimensional uneven pattern, and it is possible to sufficiently meet the needs of the times.
