この発明は、コンクリート成形板、つまり工場において
型枠を用い形成されるコンクリート製品、特にタイル張

。[Detailed Description of the Invention] [Industrial Application Field] The present invention is a concrete forming plate, that is, a concrete product formed using a formwork in a factory, particularly suitable for forming a product having a tiled three-dimensional pattern. The present invention relates to a forming method and a concrete formed plate obtained by this method.
従来より行われているコンクリート成形板の形成方法と

していた。The conventional method for forming concrete molded plates is to pour concrete slurry into a formwork and let it harden. Either a formwork with a three-dimensional female pattern was used, or actual tiles were placed in advance in the formwork before concrete was poured.
しかし、このような従来法には以下のような欠点がある
。However, such conventional methods have the following drawbacks.
雌型付の型卆を用いる場合
コンクリートスラリを型枠内に流し込んだ際に、コンク

ものであるから、どうしても一貫作業ラインから外れた
バッチ的工程によって行わざるを得ない。つまり、ピン
ホールやジャンカ−の補修作業及びこれによる工程の煩
雑化という点で生産性に劣るものである。When using a mold with a female mold, when the concrete slurry is poured into the formwork, air bubbles remain between the concrete slurry and the formwork, and these air bubbles cause pinholes and the like on the surface that is in close contact with the formwork. Small holes called junkers occur. Therefore, it is necessary to perform repair work to fill in these pinholes and junkers, but since this repair work requires a lot of manpower and effort, it has no choice but to be carried out in a batch process that is outside the integrated work line. I don't get it. In other words, productivity is poor in terms of repair work for pinholes and junkers and the resulting complexity of the process.
また、タイル張り状立体模様の表面に施す塗装が、最低

う、になってしまい、本物感が薄れてしまう。In addition, the painting applied to the surface of the tiled three-dimensional pattern requires repeating the spraying of paint at least three times, and the cost of this work is also an issue. As a result, the edges of the three-dimensional pattern naturally become rounded, making the three-dimensional pattern less clear and less realistic.
実物タイルを用いる場合

る強度低下も問題になってしまう。When using real tiles, it takes too much manpower and time to arrange the real tiles. In addition, it is difficult to dispose of concrete slag that has come around from the joints and adhered to the surface of the tiles. In other words, concrete slag impairs the aesthetic appearance of the tile surface, so it must be removed, but since the slag and tiles have high adhesion, cleaning with an acidic solution is necessary, which is not only troublesome, but also Decreased strength due to neutralization also becomes a problem.

The aim is to provide concrete molded plates.

り成形されるコンクリート成形板を提供する。Specifically, first, a thin surface layer of mortar slurry or concrete slurry is formed in the formwork, and then, after the surface layer has properly hardened, a main body layer is adhered and formed with concrete slurry behind the surface layer. A method for forming a concrete molded plate as described above, in which the surface layer is formed into a tiled shape consisting of a large number of divided block pieces, and the main body layer is inserted into the gaps between the block pieces by a certain thickness. Provided is a method for forming a concrete molded plate (first invention) in which the concrete is exposed in the form of tile joints, and based on the premise of the first invention, there is provided a tiled three-dimensional pattern in which the formwork used is composed of a large number of block pieces. A method for forming a concrete forming plate having a female mold corresponding to the above, and the female mold comprising a main female mold and an auxiliary female mold having a thickness corresponding to the constant thickness according to claim (1) (second invention) Further, based on the second invention, a method for forming a concrete forming plate in which the auxiliary female mold is brought into close contact with the main female mold by magnetic force (third invention)
Further, based on the second to third inventions, there is provided a method for forming a concrete forming plate (fourth invention) in which a flexible cushioning material is interposed between the auxiliary female mold and the main female mold. Further, based on the second to fourth inventions, there is provided a method for forming a concrete molded plate (fifth invention), which comprises spraying mortar slurry or concrete slurry onto a formwork to form a surface layer; A concrete molded plate formed by each of the above methods is provided.
このような方法における作用は以下の通りである。 The effects of such a method are as follows.
ピンホール、ジャンカ−の発生を防止
ピンホールやジャンカ−の発生を防げその補修作業が無
くて済むので、従来の方法に比べ生産性を大きく向上さ
せることができる。Preventing the occurrence of pinholes and junkers Since the occurrence of pinholes and junkers can be prevented and there is no need to repair them, productivity can be greatly improved compared to conventional methods.
ここで、ピンホールやジャンカ−の発生を防げるのは以

いために気泡の抜けがよくなって型枠との間に気泡がほ
とんど残留しなくなり、その結果ピンホールやジャンカ
−の発生を見ないものと考えられる（第１発明）。Here, the reason why pinholes and junkers can be prevented from occurring is considered to be due to the following reasons. That is, first, the surface layer is formed in close contact with the formwork, but since this surface layer is thin, air bubbles can escape easily and almost no air bubbles remain between it and the formwork, resulting in pinholes and junks. It is considered that - does not occur (first invention).
表面層と型枠との間に気泡を残留させないという点では

ャンカ−の発生を防げる（第５発明）。In order to prevent air bubbles from remaining between the surface layer and the formwork, it is even better to spray the mortar slurry or concrete slurry for the surface layer onto the formwork at high pressure; The occurrence of pinholes and junkers can be effectively prevented (fifth invention).
立体模様の鮮明化

低減できるという利点がある。Sharpening of the three-dimensional pattern There is an advantage that the tiled three-dimensional pattern on the surface can be made more clearly, and that the cost of painting the surface can be reduced.

第１発明）。In other words, in the case of concrete molded plates obtained by this method, the surface layer is separately formed as a thin layer in advance, so it is possible to increase the density of the surface layer and to make the surface layer the same color as the paint. Coloring and even waterproofing by mixing waterproofing agents into the surface layer can be done freely without worrying about strength or cost, so for surface coating, you can simply form a thinner coating with fewer sprays. You can get the same performance as the conventional one. Therefore, in the case of concrete molded plates obtained by this method, a thinner and fewer spraying process suffices with multiple surface coatings, resulting in a clearer three-dimensional pattern and a reduction in coating costs (
1st invention).

１発明）。Forming a tiled three-dimensional pattern The main body layer is inserted into the gaps between the block pieces by a certain thickness to expose it like a tile joint, so it looks like the real thing. The adhesiveness between the main body layer and the surface layer is improved accordingly, effectively preventing block pieces from falling off, and creating a tile-like three-dimensional pattern with greater durability. A concrete molded plate is obtained (first invention).

り込むようにして本体層を形成する（第２発明）。Such a tiled three-dimensional pattern is formed by using a female mold consisting of a main female mold and an auxiliary female mold. That is, first, a tiled surface layer is formed using a female mold that is a combination of a main female mold and an auxiliary female mold, and then, after removing the auxiliary female mold, concrete slurry for the main body 1 is poured, and the concrete slurry for the main body 1 is poured. The main layer is formed by penetrating the concrete slurry into the traces of the auxiliary female mold (second invention).

している。The workability of such molding work can be improved by bringing the auxiliary female mold into close contact with the main female mold using magnetic force, and by providing a flexible cushioning material on the side surface that is in close contact with the main female mold. (Third invention and fourth invention). In other words, the magnetic adhesion of the auxiliary female mold to the main female mold facilitates the adhesion of the thin and difficult-to-handle auxiliary female mold to the main female mold, and the interposition of the cushioning material allows the auxiliary female mold to come into close contact with the main female mold. This improves the surface layer slurry and reliably prevents the surface layer slurry from spilling out into the tile joints, which greatly contributes to improved workability.
以下、この発明の一実施例を図面に基づき説明する。 Hereinafter, one embodiment of the present invention will be described based on the drawings.
このコンクリート成形板の形成方法は、大まかに別けて

うなコンクリート成形板１を形成するものである。The method for forming this concrete molded plate consists of two steps, roughly divided into the formation of the surface layer 2 and the formation of the main body layer 3.First, the surface layer 2 is formed on the outer formwork FO constituting the formwork F; Next, after the surface layer 2 has been cured appropriately, that is, to the extent that the surface layer 2 will not collapse when concrete slurry for the main body layer 3 is poured, concrete slurry is poured on the back of the surface layer 2 to adhere the main body layer 3. The molded concrete plate 1 shown in FIG. 3 is formed by forming the concrete plate 1 as shown in FIG.
表面層２は分割された多数のブロック片２ｂからなるタ

みは誇張して表されている。The surface layer 2 is formed into a tiled three-dimensional pattern consisting of a large number of divided block pieces 2b, and for this reason, the outer formwork Fo is provided with a pattern as shown in FIGS. 1 and 2.
forming a female mold M corresponding to the tiled three-dimensional pattern;
Furthermore, this female mold M is formed by closely combining the main female mold Ma with an auxiliary female mold Ms that is much shallower than the main female mold Ma. For example, if the thickness of the concrete forming board 1 is 150 mm, the depth of the female mold M, that is, the thickness of the surface layer 2 is about 5 to 10 mm, that is, 3 to 6 mm of the total thickness.
% thickness. In addition, in the figure, the thickness of the surface layer 2 is exaggerated.

ためである。The reason why the female mold M is formed from the main female mold 1vIa and the auxiliary female mold MS is because the gaps between the block pieces 2b, that is, the tile joints V, are formed as shown in FIG. By putting the concrete of the main body layer 1 into the part to a certain thickness, that is, the thickness of the auxiliary female mold Ms, the adhesion between the main body layer l and the surface layer 2 is improved, and the falling off of the block pieces 2b is effectively prevented. This is to prevent damage and provide better durability.

向上することになる。That is, first, a tiled surface layer 2 is formed using a female mold M that is a combination of a main female mold Ma and an auxiliary female mold Ms, and
Then, after removing the auxiliary female mold Ms, concrete slurry for the main body layer is poured, and the main body layer 1 is formed by pouring the concrete slurry for the main body layer into the area where the auxiliary female mold Ms was removed. Then, the hardening of the main body layer 1
Due to the contraction, each block piece 2b is mechanically firmly held, and the adhesiveness between the main body layer 1 and the surface layer 2 is further improved.
成形手順の概略は以下の通りである。The outline of the molding procedure is as follows.

。Setting the outer formwork Fo with the main female mold Ma → Assembling the auxiliary female mold Ms to the main female mold Ma → Spraying the surface layer 2 → Curing the surface layer 2 (about 40 minutes) - Setting the auxiliary female mold Ms Removal → Reinforcement arrangement → Setting of inner formwork Fi → Driving of main body layer 3 → Hardening of main body layer 3 (2
4 hours) → demolding → product → surface painting (performed as necessary)

ここで、補助雌型Ｍｓを主雌型Ｍａへ密着させるには、
磁力吸着手段Ｐを用いるのが好ましい。Here, in order to bring the auxiliary female mold Ms into close contact with the main female mold Ma,
It is preferable to use magnetic attraction means P.

、このような事態を未然に避け、より効率よ（作業をす
る進め得るようにするためである。That is, since the auxiliary female mold Ms is thin and easily uneven, it is made to adhere uniformly to the main female mold Ma by magnetically attracting it so that there are no non-adhesive parts. Furthermore, a cushion material (
It is more preferable to interpose a material (not shown) to obtain a more reliable adhesion state by using the adsorption force due to magnetic force and the buffering force due to the cushion material. In this way, the auxiliary female type M
It is the auxiliary female mold M that takes care of the adhesion between s and the main female mold Ma.
If mortar slurry for the surface layer etc. enters between S and the main female mold Ma, it is necessary to remove the mortar slurry that has entered before forming the main body layer 2, but this work is surprisingly troublesome. Although this will impair overall work efficiency, the purpose is to avoid such situations and make the work more efficient.

。尚、モルタルスラリには必要に応じて硬化促進剤を添
加するようにしてもよい。Further, regarding the formation of the surface layer 2, it is preferable to spray mortar slurry (or concrete slurry as necessary) into the female mold M at high pressure. This is done by spraying mortar slurry into the female mold M at high pressure so that no air bubbles remain between the female mold M and the surface layer 2, and no pinholes or junkers are generated on the surface of the surface layer 2. It's for a reason. However, since the surface layer 2 is thin, it is possible to prevent bubbles from remaining to a considerable extent without necessarily using high-pressure spraying, so it may be applied by troweling or pouring. Incidentally, a curing accelerator may be added to the mortar slurry if necessary.

着色剤、さらには防水剤を混入させるようにする。Further, the mortar slurry for the surface layer 2 is mixed with a coloring agent and further a waterproofing agent, if necessary.
このように表面層２を着色剤や防水剤で処理しておくと
、表面層２が薄い層で前もって別に形成されるという点
から、その緻密性を高めることも強度やコストにとられ
れずに自由にできるということと相俟って、表面層２を
そのまま最終仕上げ面とすることで合成樹脂などによる
仕上げ用の表面塗装を省略できるし、また仕上げ用の表
面塗装を施すについても、この表面塗装層を薄いもので
済ますことができる。そして、表面塗装層を省略でき、
あるいは薄いもので済ますことができるということは、
これによる経済的メリットは勿論として、コンクリート
成形板ｌの表面層２のタイル張り状立体模様をより鮮明
なものにできるという大きなメリットをもたらす。If the surface layer 2 is treated with a colorant or waterproofing agent in this way, the surface layer 2 is a thin layer that is formed separately in advance, so it is possible to increase its density without worrying about strength or cost. Coupled with the fact that it can be done freely, it is possible to omit finishing surface coating with synthetic resin etc. by using surface layer 2 as the final finished surface, and also when applying finishing surface coating, this surface The paint layer can be made thinner. And the surface coating layer can be omitted,
Or, the fact that you can get away with a thin one,
This brings about not only economical advantages but also the great advantage that the tiled three-dimensional pattern of the surface layer 2 of the concrete molded plate 1 can be made clearer.
本体層３は前述のように表面層２の裏に鉄筋Ｚを組んだ
後にコンクリートスラリを打ち込んで形成されるコンク
リート層で、その配合は従来のものと同様である。The main body layer 3 is a concrete layer formed by pouring concrete slurry after assembling reinforcing bars Z on the back side of the surface layer 2 as described above, and its composition is the same as that of the conventional one.
