Abstract

PURPOSE:To simplify the operation and speed up the work by applying a resin undercoat on a primer-coated work surface, installing thin sheet forms with a specified pattern to pour hardening resin, and then spraying aggregate to form a surface layer material. CONSTITUTION:The foundation bed 1 of road is coated with a primer 2, and an acrylic resin comprising a methyl methacrylate composition is applied as an undercoat to form an undercoat layer 3. Then, forms 4 for block pattern are installed, and the resin is poured into a space surrounded by the forms. Next, color sand is sprayed on the resin surface by using a pressurized sprayer. When the curing of resin proceeds, the portion above the forms is smoothed and accumulated excess color sand is removed. When the curing proceeds further, the forms are removed from the foundation bed to form a surface layer material 5. A topcoat compound is applied on surface of polished surface layer material to form a topcoat layer 6. This method saves the working cost and shortens the traffic shut-off time for the work.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application J] The present invention relates to a method for forming a three-dimensional pattern on a construction surface, such as a road surface, on which a three-dimensional pattern is to be formed. More specifically, the present invention relates to a method for quickly forming a tile-like three-dimensional pattern on a construction surface using a surface material made of resin and aggregate.

[Conventional technology] In order to form a three-dimensional pattern on a construction surface such as a platform or a promenade in a park, so-called formwork is used to form formwork tiles with a three-dimensional pattern hardened with a surface material made of aggregate-containing resin on the construction surface. Tile construction method is used.

In this type of formwork tile construction method, using formwork,
Applying a mixture of aggregate and resin, such as colored sand,
The construction method used is to harden the resin and finish it into a predetermined pattern.

In the conventional formwork tile construction method, a resin serving as a joint material is applied on the construction surface that is usually coated with a brimer, a formwork that forms the tile pattern is laid, and then a hardening resin liquid and aggregate are applied. Distribute and fill the mixture into the formwork, level the surface of the mixture with a trowel, etc., peel off the release paper attached to the top of the formwork, and after the resin liquid has hardened to a certain extent, peel off the formwork from the construction surface. The surface of the surface layer material formed according to the pattern of the formwork is finished by Totsubuko.

[Problems to be solved by the invention] However, in this conventional construction method, the construction operations are complicated, which not only takes time and increases the construction cost, but also causes problems such as platform repair work. The drawback was that it would not be possible to respond to situations where construction work was completed late at night when no passengers were passing, and the traffic blockade had to be lifted by the time the first train departed.

Therefore, there has been a desire for a method for forming a three-dimensional pattern on a construction surface that can quickly complete construction with simple operations.

The inventor of the present invention has arrived at the present invention as a result of studying a method for forming a three-dimensional pattern on a construction surface that eliminates the drawbacks of conventional methods, allows quick construction, and provides a durable and beautiful finish.

[Means to solve the problem] That is, the present invention.

The brimer-treated construction surface is undercoated with resin, a thin sheet or sheet-shaped formwork with a predetermined pattern is laid on top of it, and then the area partitioned by the formwork is filled with a curable resin liquid. Next, aggregate is sprayed onto the resin liquid, and after the resin has hardened, the excess sprinkled aggregate is removed, and the resin liquid is further hardened to form a surface material made of resin and aggregate. After the pattern has been formed, the method for forming a three-dimensional pattern on a construction surface is characterized by peeling off the formwork from the construction surface, and further rubbing the surface of the surface layer material.

The present invention also includes an embodiment in which the formwork is peeled off from the construction surface, the surface is polished, and then top coated.

In the present invention, the surface material is made of synthetic resin containing aggregate. The resin is a viscous liquid hardening resin that can be filled into the formwork and hardens during construction on site.

Acrylic resins, epoxy resins, polyester resins, urethane resins, and the like can be used, and acrylic resins are particularly suitable. Examples of acrylic resins include (meth)acrylic acid and its esters,
Particularly suitable is methyl methacrylate. The viscosity of the resin liquid when filling the mold can be appropriately selected in consideration of fluidity, subsequent curing time, and the like. As a curing agent for the resin, a peroxide such as benzoyl peroxide (BPO) or an azo compound is used, and BPO is suitable. Furthermore, if necessary, amines or the like can be used as a room temperature curing accelerator.

The aggregate contained in the surface material colors the surface material and gives it a beautiful finish, as well as providing wear resistance and anti-slip effects. Examples of such aggregates include colored sand, emery stone, ceramic sand, and silica sand, but a colored sand-like substance called colored sand is particularly preferably used because it gives an aesthetic appearance. Color sand is a mixture of natural sand or synthetic ceramic with pigments, and various commercially available products such as a simple mixture of the two or a melt-blended mixture can be obtained and used.

In the present invention, in forming the surface layer material, unlike conventional methods,
First, a hardening resin liquid is filled on the construction surface where the formwork is laid,
Then, before the hardening resin liquid hardens, aggregate is sprayed onto it. Therefore, the curable resin to be injected does not need to contain an aggregate such as colored sand, but a solid material such as fine silica sand can be added as necessary to adjust the viscosity. In particular, when forming a three-dimensional pattern on an inclined construction surface base, it is effective to add such a solid substance as a thickener. The amount of solids added is not particularly limited, but preferably 20
% or less, and if it is more than this, the injection operation becomes complicated.

In this way, in the present invention, filling the aggregate is done in a separate process from filling the curable resin liquid, so the filling operation is simple, and since the filling of the aggregate is done by spraying, this is also very easy. It can be done easily. Furthermore, the surface material component consisting of resin and aggregate filled in separate processes in this way is
After the resin had hardened to some extent, a tool such as a cleaner was used to remove the excess aggregate from the top of the formwork, leaving the surface in almost good condition. In the present invention, it is preferable to polish the surface of the surface material after removing the formwork and before applying the top coat, but by adding such a polishing step, a more beautiful and stronger surface material can be formed. .

The surface of the surface layer material is polished using a device such as a grindstone polisher.

In this way, the present invention eliminates the difficulty of operation caused by mixing the entire aggregate with the resin liquid in advance and filling the mixture as in the conventional method, and also eliminates the difficulty of operation caused by mixing the entire aggregate with the resin liquid in advance and filling it with the mixture, unlike the conventional method. Although the complicated operation of leveling with a trowel etc. was required, the present invention is significantly easier to operate than this, and the time required for construction can be significantly shortened.

In the present invention, the construction surface is first treated with a brimer, and then undercoated with a resin that will serve as a joint material.

Brimer and resin primer are applied over the entire surface. Since the surface resin layer is not formed on the part where the formwork is laid, the undercoat resin remains on the surface and serves as the joint material. Various curable resins can be used for the brimer and undercoat resins, but acrylic resins are most suitable, just like the surface layer resins. The undercoat resin can be colored arbitrarily, but in order to make the pattern formed by the formwork more vivid, it is preferable to color it in a color that contrasts with the color of the surface layer material.

The formwork is for forming a pattern on the surface material, and has a shape obtained by cutting out the surface material forming part from a thin sheet.
Depending on the purpose, in addition to block patterns, shell patterns, circle patterns, etc. as shown in Figure 2 (A) to (C), various patterns such as triangle patterns, slide block patterns, and random patterns may be used. Can be used arbitrarily. The formwork uses units of a certain size in succession, but the size of one formwork unit is usually around 600ffImX100C)+m,
The thickness is 1 to 3 fflIm, usually around 2III1. The best material for the formwork is plastic because it is easy to mold, and soft foamed plastic is particularly advantageous because it is lightweight and inexpensive. Both crosslinked and non-crosslinked flexible foam plastics can be used. Examples of such flexible foamed plastics include foamed polyethylene and polyurethane, with foamed polyethylene being particularly preferred.

The formwork must be able to be easily applied to the primed construction surface and tightly adhered to it, and be easily removed after the resin has hardened, so a pressure-sensitive adhesive is applied to the back side, and release paper is applied on top of it. It is suitable to have a structure in which 2 layers are laminated. Moreover, water-repellent paper or film can be laminated on the upper surface of the formwork, if necessary. By laminating such water-repellent papers or films, processing after filling with surface layer components becomes easier. To impart water repellency, a silicone-based or wax-based substance is applied by spraying or the like.

Top coat is the final finishing touch to the surface material, and is usually applied by applying a stain-resistant resin such as acrylic resin using a roller, brush, spray, or other method.

The three-dimensional pattern forming method of the present invention can be applied to the formation of three-dimensional patterns on the surfaces of columns and walls, as well as on road surfaces such as platforms, concourses, park promenades, paved roads, and building floors. In construction, liquid hardening resin is filled into the formwork, so construction on a horizontal road surface is most suitable, but after construction is done horizontally, objects with three-dimensional patterns are moved and assembled , it can also be applied to pillars, walls, etc.

[Example] Hereinafter, an example of a method of forming a three-dimensional pattern on a road surface according to the present invention will be described with reference to the drawings.

In FIG. 1, a road surface base 1 is treated with an acrylic primer 2 and then undercoated with a gray acrylic resin consisting of a methyl methacrylate composition to form an undercoat layer 3.

Next, a block pattern formwork 4 made of foamed polyethylene having a thickness of 21 mm and having the shape shown in FIG. 3(A) is laid.

Water-repellent paper treated with silicone resin is laminated on the top surface of the formwork, and adhesive material is applied to the back surface.1! Since the pattern is pasted on, the female pattern is peeled off and the formwork is adhered to the undercoated surface of the construction surface base.

Separately, a liquid acrylic curable resin containing methyl methacrylate as a main component and BPO added as a polymerization initiator was prepared, and this was injected into the area surrounded by the mold.

Next, brick-colored colored sand ("Albel" manufactured by Yuka Industries) was sprayed onto the resin surface using a pressure-air sprayer. After the color sand was sprayed, the mold was left to stand, and when the resin had hardened, the top of the mold was smoothed using a cleaner to remove excess color sand that had accumulated on the resin. When the resin had further hardened, the formwork was peeled off from the base.

(Thus, a brick-colored surface material 5 made of hardened resin and colored sand was formed in the area partitioned by the formwork. The surface of this surface material was polished using a grindstone polisher, and then the polished surface layer An acrylic top coat agent was applied to the surface of the material to form the top coat layer 6 shown in FIG. 2, and thus a road surface having a three-dimensional block pattern with a cross section as shown in FIG. 2 was obtained.Unit The amounts of various materials used per area are as follows.

Brimer: 0.4 Kg/rn' Undercoat layer: 2.0 Kg/rn'Top coat layer: 0.6 g/g By spraying the plastic resin after filling it, the operation is simplified and construction can be completed more quickly, reducing construction costs and shortening the time required for traffic closures during construction of roads, platforms, etc. etc., it has many effects.
