A fluid (hereinafter referred to as ``agar-like substance'') is poured and hardened into a jelly-like state, and then mortar is placed to embed stones, and then concrete is placed on top of it. After the concrete is cured, it is molded, the reinforcing sheet is peeled off, the jelly-like substance is removed, and the concrete is washed with water.

材顆間の砂を除去する。(n) Method proposed in Japanese Patent Application No. 1-183905: After laying sand on the bottom plate of the formwork and embedding stones in the sand layer so that some of them protrude, fast-hardening mortar is applied. The mortar is poured onto the surface of the sand layer between the stone condyles, and after the mortar begins to harden, concrete is poured and cured, followed by demolding and the sand between the stone condyles is removed.
［発明が解決しようとする課題］
上記方法のうち、（Ｉ）の方法は、次のような欠点があ
る。[Problems to be Solved by the Invention] Among the above methods, method (I) has the following drawbacks.
■ 寒天状物質を、石材間の目地部に流し込む際に、後
から打設するコンクリート等との付着面となる石材上面
や側面に寒天状物質が付着し易い。■ When agar-like substances are poured into joints between stones, the agar-like substances tend to adhere to the top and side surfaces of the stones, which are the surfaces to which concrete, etc. that will be placed later will adhere.
この付着した寒天状物質が硬化したまま、コンクリート
等を打設すると石材とコンクリート等との付着性が悪く
、石材が剥げ落ちる危険性がある。If concrete or the like is poured while this adhered agar-like substance remains hardened, the adhesion between the stone and the concrete will be poor and there is a risk that the stone will peel off.
特に、目地部が小さい場合には、寒天状物質を目地部の
みに流し込むことは難しく、上記の理由により石材の剥
離が起こり易い。Particularly when the joints are small, it is difficult to pour the agar-like substance only into the joints, and the stones are likely to peel off for the reasons mentioned above.
■ 寒天状物質を溶融し、目地部に流し込むという作業
に手間がかかる。■ Melting the agar-like substance and pouring it into the joints is a time-consuming process.
■ 寒天状物質の上に直接コンクリートを打ち込むと、
寒天状物質の層を乱してしまい、目地部の仕上りが悪く
なる。このため、まず、モルタルを流し込み、モルタル
の硬化開始後に、コンクリートを打ち込まなければなら
ない。従って、製造工程が増えるため、その分生産性が
悪くなる。■ When concrete is poured directly onto the agar-like material,
This disturbs the layer of agar-like substance, resulting in poor finish at the joint area. For this reason, mortar must first be poured, and after the mortar has begun to harden, concrete must be poured. Therefore, since the number of manufacturing steps increases, productivity deteriorates accordingly.
また、（ＩＩ）の方法では、次のような欠点がある。Furthermore, the method (II) has the following drawbacks.
■ （Ｉ）の方法と同様に、砂層の上に直接コンクリー
トを打ち込むと、砂層を乱してしまい、目地部の仕上り
が悪くなる。このため、まず、モルタルを流し込んで、
モルタルの硬化開始後に、コンクリートを打ち込まなけ
ればならない。従って、製造工程が増えるため、その分
生産性が悪くなる。■ Similar to method (I), pouring concrete directly onto the sand layer disturbs the sand layer, resulting in poor joint finish. For this reason, first pour the mortar,
After the mortar begins to harden, concrete must be poured. Therefore, since the number of manufacturing steps increases, productivity deteriorates accordingly.
本発明は上記従来の問題点を解決し、化粧仕上げブロッ

結遅延剤をさす。In the present invention, the super retardant is defined in Japanese Patent Publication No. 2-15
519, which has the property of temporarily stopping the hydration reaction of cement, delaying setting for an extremely long period of time, and then starting the reaction again. As expected.
以下に本発明を図面を参照して詳細に説明する。The present invention will be explained in detail below with reference to the drawings.
第１図及び第２図は本発明の化粧仕上げブロックの製造
方法の一実施方法を説明する断面図である。FIGS. 1 and 2 are cross-sectional views illustrating one implementation method of the decorative finished block manufacturing method of the present invention.
まず、第１図を参照して請求項（１）の方法について説

請求項（１）の方法では、まず、型枠１の底板２の型面
に超遅延剤３を付着させ、その上に石材類４を配置する
（第１図（ａ））。In the method of claim (1), first, a super retardant 3 is attached to the mold surface of the bottom plate 2 of the formwork 1, and stones 4 are placed thereon (FIG. 1(a)).
次に、このようにして処理した後の型枠１内に、コンク
リート５を打ち込む（第１図（ｂ））。Next, concrete 5 is poured into the formwork 1 that has been treated in this manner (FIG. 1(b)).
そして、所定の養生を行なってコンクリート５を硬化さ

第１図（ｄ））。Thereafter, the bottom plate abutting surface 6A of the obtained block 6 is washed and treated using high pressure water, a brush, or the like according to a conventional method. The hardening of the layer on the side of the bottom plate contact surface 6A of the block 6 is delayed by the action of the super retardant 3 attached to the surface of the bottom plate 2 of the formwork 1 and is in an uncured state. The decorative finished block 10 in which the stone material 4 is buried so that a portion thereof is exposed is obtained by easily removing the part (

The remaining portion forms a joint between the stone condyles. The hardening of this infiltrated mortar and the mortar forming the joints is inhibited by the ultra-retardant on the bottom plate or plate surface, so after curing and demolding, it can be easily removed by washing out with water and a brush or high-pressure water. be able to. And 2~3m
It is possible to obtain a highly decorative decorative block having a joint depth of about m, with a part of the stone exposed. Moreover, there are no restrictions on the curing method or the timing of cleaning after demolding.
Even in the case of accelerated curing, washing can be carried out at any time, which is extremely advantageous.

する。According to the method for manufacturing decorative finished blocks of the present invention, unlike the method disclosed in JP-A No. 63-264302, an agar-like substance is not used, so the adhesion of the agar-like substance makes it difficult to bond with stones. Adhesion to concrete does not deteriorate, and there is no need for the time-consuming work of melting agar-like substances. In addition, in Japanese Patent Application Laid-Open No. 63-264302, it is placed on an agar-like substance, and in Japanese Patent Application No. 1-183905, it is placed on a sand layer.
Concrete must be placed after pouring mortar, but in the present invention there is no need to pour mortar and concrete can be placed directly, improving productivity.
