【発明の詳細な説明】
ｒ、発明の目的Ｃ
（産業上の利用分野）
本発明はコンクリートまたはモルタルの成形方法に関す
る。DETAILED DESCRIPTION OF THE INVENTION r.Object of the Invention C (Field of Industrial Application) The present invention relates to a method for forming concrete or mortar.
（従来の技術）
従来、中空の製品をコンクリートまたはモルタルを用い
て遣る場合、予め外型枠の内部に中子を入れ、外型枠と
中子との間にコンクリートまたはモルタルを流し込み、
これか外型枠と中子を脱型しても墳れない程度に硬化し
た後に、外型枠と中子とを脱型して成形していた。(Prior art) Conventionally, when using concrete or mortar for hollow products, a core is placed inside an outer form in advance, and concrete or mortar is poured between the outer form and the core.
After this, the outer form and core were removed from the mold and molded after it had hardened to such an extent that the mound could not be filled even if the outer form and core were removed.
（発明が解決しようとする課題） 上記した従来の成形方法では中子が必要である。(Problem to be solved by the invention) The conventional molding method described above requires a core.
したがって製品の形状が複雑であれば、それに応じて中
子の型枠形状も複雑となり、一定の厚さの中空製品を成
形すること及び中子の脱型が非常に難しかった。Therefore, if the shape of the product is complicated, the shape of the mold for the core will be correspondingly complicated, making it very difficult to mold a hollow product of a certain thickness and to demold the core.
更に製品が肉薄の場合には、強度が低く破損することが
あった。Furthermore, if the product is thin, its strength may be low and it may break.
本発明は上記事情に鑑みてなされたものであり、複雑な
形状の中辛製品てあっても一定の肉厚で成形することの
可能なコンクリートまたはモルタルの成形方法を提供す
ることを目的としている。The present invention has been made in view of the above circumstances, and aims to provide a method for forming concrete or mortar that can be formed with a constant wall thickness even if it is a medium-spicy product with a complex shape. .
［発明の構成］
（課題を解決するための手段及び作用）上記目的を達成
するため、本発明は吸水性ある型枠内にコンクリートま
たはモルタルを流し込み、型枠内面に接してコンクリー
トゴたはモルタルの′＃集層が所定厚さ形成された後、
型枠内部の未硬化のコンクリートまたはモルタルを排出
し、養生後に脱型する処理を行なう。[Structure of the invention] (Means and effects for solving the problem) In order to achieve the above object, the present invention pours concrete or mortar into a water-absorbing formwork, and pours concrete or mortar into a water-absorbing formwork, and pours concrete or mortar into the formwork so that the concrete or mortar After the layer is formed to a predetermined thickness,
The uncured concrete or mortar inside the formwork is discharged and removed from the form after curing.
このようにすることにより、中子を不要とし、かつａ雑
な中空製品を簡単につくることか可能である。By doing so, it is possible to eliminate the need for a core and easily produce a crude hollow product.
（実施例） 以下図面を参照して実施例を説明する。(Example) Examples will be described below with reference to the drawings.
第１図は本発明によるコンクリートまたはモルタルの成
形方法を説明する図であり、第１図（ａ）は型枠のみを
示す。そして本実施例では花瓶を成形する場合て説明す
る。なお、各図は断面図になっている。FIG. 1 is a diagram illustrating the concrete or mortar forming method according to the present invention, and FIG. 1(a) shows only the formwork. In this embodiment, the case of molding a vase will be explained. Note that each figure is a sectional view.
第１図（ａ）において、１は吸水性の高い石膏からなる
型枠であり、この場合、内部形状は花瓶の輪郭になって
いる。２は分割線てあり、この部分から型枠が分離する
。In FIG. 1(a), numeral 1 is a mold made of highly water-absorbing plaster, and in this case, the internal shape is the outline of a vase. 2 is a dividing line from which the formwork is separated.
第１図（ｂ）は前記した型枠内にモルタル３を流り込ん
だ状態を示し、この状態から４０分程度経過したとき、
第１図（Ｃ）に示すように、型枠筒内面に接してモルタ
ルの凝集した層４がてきる。これは型枠１に接する部分
の水分か石膏に吸水されるためである。FIG. 1(b) shows the state in which the mortar 3 has been poured into the formwork described above, and when about 40 minutes have passed from this state,
As shown in FIG. 1(C), a layer 4 of agglomerated mortar comes into contact with the inner surface of the cylinder of the form. This is because the moisture in the area in contact with the formwork 1 is absorbed by the plaster.
本実施例ては型枠の高さ１２＝３００ｎｎ＋ 、 ｌ
１−１００ｎｎの場合、１３は約１０１の厚さく時間
４０分）となった。In this example, the height of the formwork is 12=300nn+, l
In the case of 1-100 nn, the thickness of 13 was about 101 and the time was 40 minutes).
第２図はモルタルの配合を示す図てあり、本実施例の場
合、セメント、水、細骨材にグラスファイバーを加えた
。これは花瓶の肉厚が１０ｎｍと薄いなめ、補強材とし
て加えたちのである。なお、本実施例てはグラスファイ
バーの量は全容積比の２％とした。FIG. 2 shows the composition of mortar, and in the case of this example, glass fiber was added to cement, water, and fine aggregate. This is because the wall of the vase is as thin as 10 nm, and was added as a reinforcing material. In this example, the amount of glass fiber was 2% of the total volume ratio.
次に、第１図（Ｃ）において、型枠内部の未硬化のモル
タル３を捨てる。そして２４時間程度養生すると、モル
タルの凝集層４が型枠を脱型しても壊れない程度に硬化
する。そこで型枠を分離させて脱型すればよい。Next, in FIG. 1(C), the uncured mortar 3 inside the formwork is discarded. After curing for about 24 hours, the cohesive layer 4 of mortar hardens to such an extent that it will not break even if the mold is removed. Then, the formwork can be separated and demolded.
上記実施例ては型枠の材質として石膏の場合を説明した
が、これに限定されるものではなく、例えば硅そう土て
も、あるいは金属型の内側に吸水シートを貼着したもの
等であってもよい。In the above embodiments, the case where plaster is used as the formwork material is explained, but the material is not limited to this. For example, silica clay, or a material with a water-absorbing sheet pasted on the inside of a metal mold, etc. You can.
又、肉薄の製品に添加する材質としては、グラスファイ
バーに限定されるものではなく、カーボンファイバー等
のｍ雌状の補強材てあればよい。Further, the material to be added to the thin product is not limited to glass fiber, and any reinforcing material such as carbon fiber may be used.
