Abstract

In the decoration mat of this invention, a large number of colored particles are distributed on a rugged pattern transfer surface through an adhesive layer the bonding power of which decreases upon water absorption. A method of forming a pattern on a concrete surface according to this invention comprises pouring a concrete material using the rugged pattern transfer surface of the decoration mat as a contact surface with the concrete surface, reducing the bonding power of the adhesive layer by the moisture of the concrete material, transferring and burying the colored particles into the concrete surface, and forming the concrete surface into the rugged pattern surface by the transfer of the rugged pattern transfer surface. In the method of this invention, the bonding power of the adhesive layer is reduced by the moisture of the concrete material during aging and curing after pouring, and the colored particles retained by the adhesive layer are transferred to, and buried into, the surface layer of the concrete material. Accordingly, colors of natural color tones can be expressed on the surface layer of the concrete molded article. Since the colored particles do not undergo discoloration, fading and deterioration, a rugged pattern retaining high durability for a long time can be obtained.

本発明は、 コンクリート表面に対する模様成形法およびそれに用いる化粧マツ トに関するものである。  The present invention relates to a method for forming a pattern on a concrete surface and a decorative mat used for the method.
背景技術  Background art
従来、 コンクリート表面にカラ一表現された凹凸模様を形成する場合、 つぎの ような方法が行われている。 すなわち、 まず、 図 4に示すような化粧マット （化 粧型枠） 1 0を用意する。 この化粧マット 1 0は硬質のウレタン発泡体で構成さ れ、 一方の面が、 コンクリート材料に接触してコンクリート表面に凹凸模様を転 写する凹凸模様転写面 1 3に、 他方の面が平坦な背面 1 4に形成されている。 こ の化粧マット 1 0は、 内部に発泡層 1 1を、 表層部分にインテグラルスキン層 1 2を備えており、 このインテグラルスキン層 1 2は、 実質的に気泡が存在しない か、 または存在するとしても極めて微小な気泡が存在するにすぎない層であり、 上記発泡層 1 1に比べて高密度で緻密に形成され、 表面平滑性に富んでいる。 こ のインテグラルスキン層 1 2の平滑な表面で上記凹凸模様転写面 1 3が形成され ている。 このような化粧マット 1 0の凹凸模様転写面 1 3に施工現場で離型剤を 塗布し、 ついで、 図 5に示すように、 上記化粧マット 1 0と型枠 1 6とを正面対 設状態で配置し、 側方の開口と底部の開口 （図示せず） を板材等で塞き、 上部開 口からコンクリート材料 1 5を流し込む。 1 7は板材である。 そののち、 上記コ ンクリート材料 1 5を硬化させてコンクリート化させ、 これを、 図 6に示すよう に、 上記化粧マツト 1 0から雔型させる。 このようにして得られたコンクリート 板 1 8の表面には上記化粧マット 1 0の凹凸模様が転写されて、 自然石風の凹凸 模様が形成されるようになる。 そののち、 上記凹凸模様面に吹付け材等で塗装が 行われてカラー表現され一層自然調が強調される。  Conventionally, the following method has been used to form a concavo-convex pattern on a concrete surface. That is, first, a decorative mat (decorative formwork) 10 as shown in FIG. 4 is prepared. This decorative mat 10 is made of a hard urethane foam, and one surface has an uneven pattern transfer surface 13 that contacts the concrete material and transfers the uneven pattern to the concrete surface, and the other surface has a flat surface. Formed on the back 14. This decorative mat 10 has a foam layer 11 inside and an integral skin layer 12 on the surface layer, and the integral skin layer 12 is substantially free of air bubbles or present. Even so, it is a layer in which only very small air bubbles are present. The layer is denser and denser than the foamed layer 11, and has excellent surface smoothness. The uneven pattern transfer surface 13 is formed on the smooth surface of the integral skin layer 12. A release agent is applied to the uneven pattern transfer surface 13 of the decorative mat 10 at the construction site, and then, as shown in FIG. 5, the decorative mat 10 and the formwork 16 are in front of each other. The side opening and the bottom opening (not shown) are closed with a plate or the like, and concrete material 15 is poured from the upper opening. 17 is a plate material. After that, the concrete material 15 is hardened and turned into concrete, and as shown in FIG. The concave and convex pattern of the decorative mat 10 is transferred to the surface of the concrete plate 18 thus obtained, and a natural stone-like concave and convex pattern is formed. After that, the above-mentioned uneven pattern surface is painted with a spraying material or the like, and is expressed in color to further emphasize the natural tone.
しかしながら、 上記塗装に用いられる塗料には有機系の塗料が多く、 変色した り、 褪色したりしゃすいうえ、 塗料中の有機材が劣化しやすいため、 無機系の材 質 （例えば天然石等） を用いて模様成形したものと比べて長期の耐久性に劣る。 したがって、 一定期間後に上記塗装が行われた凹凸模様面を塗り変えなければな らず、 この塗り変え （リフレッシュ） 等のメンテナンスに多大の費用を要する。 本発明は、 このような事情に鑑みなされたもので、 長期にわたって耐久性に優 れて塗り変える必要のない自然調等のコンクリートを形成しうる模様成形法およ びそれに用いる化粧マツトの提供をその目的とする。 However, many of the paints used in the above coatings are organic paints, which are discolored, faded, or washed, and the organic materials in the paint are easily degraded. It is inferior in long-term durability as compared with those formed by patterning using quality (eg, natural stone). Therefore, after a certain period of time, it is necessary to repaint the uneven surface on which the above-mentioned painting has been performed, and maintenance such as repainting (refreshing) requires a large cost. The present invention has been made in view of such circumstances, and provides a pattern forming method capable of forming a concrete such as natural tone which is excellent in durability for a long time and does not need to be repainted, and to provide a decorative mat used therefor. With that purpose.

Prepare a decorative mat in which a large number of colored particles are distributed on the transfer surface of the uneven pattern through an adhesive layer whose adhesive strength is reduced by water absorption, and contact the transfer surface of the decorative pattern of the decorative mat with the concrete surface. A concrete material is cast on the concrete surface, the adhesive force of the adhesive layer is reduced by the moisture of the concrete material, the colored particles are transferred to the concrete surface and buried, and the concrete surface is transferred by the transfer of the concave-convex pattern transfer surface. A method of forming a pattern on a concrete surface, characterized in that the pattern is formed on an uneven pattern surface.
2 . 凹凸模様転写面に、 吸水により粘着力が減少する粘着層を介して多数の着色 粒状物が分布されていることを特徴とする化粧マツト。  2. A decorative mat, characterized in that a large number of colored particles are distributed on an uneven pattern transfer surface via an adhesive layer whose adhesive strength is reduced by water absorption.
