JP2015077771A - METHOD FOR DRAWING ON CONCRETE SURFACE BY TRANSFERRING PATTERN OR PHOTOGRAPH USING MOLD OF METAL SHEET OR RESIN MATERIAL SUCH AS ACRYL WITH MANY HOLES AND HIGH-PRESSURE WATER AT ABOUT 150 Mpa - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a method for transferring patterns and photographs to a concrete surface for formation of a decorative concrete, eliminating conventional complicated workability which leads to high costs, capable of transferring minute patterns and photographs to a concrete surface.SOLUTION: A metal sheet or a sheet of resin material such as acryl is subjected to a transfer processing for forming many holes with a press or by laser based on dotted (halftoned) pattern or photograph data. The sheet is closely contacted with a concrete surface. The concrete surface exposed from the many holes of the sheet is cut with discharged water from a high-pressure washing machine at about 150 Mpa, so that the pattern or the photograph is transferred to the concrete surface. The drawing method eliminates complicated workability with drastically simplified construction procedure, achieving reduction in costs. Due to use of a concrete in the stage of completion of coagulation, the method can be thoroughly independent from concrete installation technique.

Description

  The present invention relates to a decorative concrete forming technique for transferring a pattern, a photograph, or the like to a concrete surface. A metal plate or a resin material such as acrylic is used as a mold and a high pressure water of about 150 MPa is used on a concrete surface. The present invention relates to a construction method that is beneficial for transferring patterns and photographs.

  Of the decorative concrete formation technology that transfers designs and photographs to the concrete surface, the drawing technology on the concrete pavement surface places the ground concrete as a method of creating a decorative road surface by exposing stones to the surface of the concrete pavement surface. Then, after placing concrete for makeup mixed with stones in the upper layer and integrating the base concrete and cosmetic concrete, the surface concrete is removed by sandblasting, exposing the stone to the surface and making the cosmetic road surface A method of making is proposed. In addition, as a method for forming a concave portion having a predetermined pattern on the decorative road surface, a method of embossing with a rubber mold or the like before the surface decorative concrete is cured has been proposed. In the drawing technology that transfers the paving stones or the design and photos on the wall surface to the concrete surface, a concrete setting retarder is applied to the formwork, and after setting the cast concrete, the part where the setting is delayed is washed away by the retarder. Have proposed a method of transferring a pattern, a photograph or the like onto a concrete surface (Japanese Patent Application No. 61-179295, Japanese Patent Application No. 2006-347250, Japanese Patent Application No. 9-969). And a method of applying to a sheet such as a film and sticking to a formwork. As a method of applying to a sheet such as a film and affixing it to a mold, there is provided a method of printing on a sheet such as a film using a setting retarder as an ink material (Japanese Patent Application No. 61-179295).

  After placing the foundation concrete, cast concrete with stone mixed in the upper layer, and after the foundation concrete and makeup concrete are integrated, the concrete on the surface is removed by sandblasting to expose the stone to the surface. In the technology to make the road surface for makeup, it is pointed out that the degree of cutting is insufficient as the technology to transfer the pattern and photograph etc. to the concrete surface by using sandblasting, High costs are also pointed out. In addition, it has been pointed out that the effect on drawing by destroying aggregates by sandblasting. It has been pointed out that the technique of embossing with a rubber mold etc. before the cosmetic concrete on the surface hardens is difficult to express precisely, and because the concrete before hardening is used, The above restrictions are pointed out. In the technology that uses a concrete surface setting retarding agent as an ink material and prints on a sheet such as a film, because the concrete in an unset stage is used, the success or failure of drawing, such as the prevention of the occurrence of beans board (so-called junkers), cold joints, etc. It is pointed out that there are many places that depend on the technology of placing concrete and that there are many restrictions due to the shape of the formwork. Furthermore, it is pointed out that it is impossible to depict existing concrete surfaces.

  Therefore, an object of the present invention is to provide a technique that can be used to eliminate the complicated workability that is also an incentive to increase the cost of the prior art and to transfer a detailed pattern or photograph to a concrete surface.

  In order to solve the above problems, the invention of claim 1 is a metal plate or a sheet of resin material such as acryl, which has been punched by a press or a laser, and a high pressure around 150 Mpa. Using an ultra-high pressure washer capable of discharging water (hereinafter referred to as "ultra-high pressure washer"), we provided a technology to cut the concrete surface and transfer patterns such as figures and photographs. According to the second aspect of the present invention, the surface of the concrete is transferred to a metal plate or a sheet of resin material such as acrylic by performing a number of perforations using a press or laser, and water discharged from an ultra-high pressure washer. We provided a drawing technology that cuts the surface of the concrete exposed through a hole in a sheet of a metal plate or a resin material such as acrylic, and transfers a pattern, a photograph, or the like onto the concrete surface. According to the invention of claim 3, when the concrete surface is cut, in order to keep an appropriate concrete cutting so as not to cause excessive concrete destruction, the discharge water pressure of the ultrahigh pressure washer is about 100 to 200 MPa, the discharge water amount is 2 to 2 per minute. Provided about 6L. The invention of claim 4 provides a drawing technique for coloring a cutting surface by mixing a pigment into water discharged from an ultra-high pressure washer.

  Using a metal plate or a die made by punching a large number of holes in a resin material such as acrylic and an ultra-high pressure washer, it is complicated to provide a technology that cuts the surface of the concrete and transfers graphics and photographs. The workability is eliminated, the construction procedure is greatly simplified as compared with the prior art, and the cost can be reduced.

  Furthermore, since the concrete is cut only with the water of the ultrahigh pressure washer, the aggregate is not destroyed and the drawing is not affected.

  Furthermore, since the concrete at the stage of setting is used, the success or failure of drawing is completely not affected by the technology of placing concrete, such as the generation of bean plates (so-called junkers) and cold joints. In addition, because the concrete at the setting completion stage is used, the work can be done while confirming the success or failure of the drawing. As a result, it is possible to overcome the disadvantages of the prior art at the uncondensed concrete stage where the success or failure cannot be confirmed and cannot be corrected. Therefore, it is possible to provide a technology that can be used for transferring a fine pattern or a photograph to a concrete surface.

  Furthermore, the drawing technique which colors a cutting surface by mixing a pigment with the discharge water from an ultrahigh pressure washer was provided. As a result, it is possible to provide a technique for transferring a pattern or photograph having a completely novel expression on the concrete surface.

Hereinafter, the actual form of the present invention will be described.
