Description

本発明は、庭石、置物（例えば、灯籠）、車止め、ブロック等を造形物本体として、その表面を自然石風に見せた自然石風な造形体の製造方法に関する。 The present invention relates to a method for manufacturing a natural stone-like shaped body in which a garden stone, a figurine (for example, a lantern), a car stop, a block, and the like are used as a main body of the shaped article and the surface of the shaped body looks like a natural stone.

例えば、特許文献１には、軽量芯材と、この軽量芯材を包む網体と、防水用モルタルが固化してなり、網体を被覆する防水性の第一の硬質層と、灰墨を含むモルタルが固化してなり、第一の硬質層を被覆する第二の硬質層と、第二の硬質層を被覆する着色層を有する、芯材や網体の変質や腐食を防止する人造石及びその製造方法が提案されている。 For example, in Patent Document 1, a lightweight core material, a net body that encloses the lightweight core material, a waterproof mortar that is solidified, and a waterproof first hard layer that covers the net body and black ink are disclosed. An artificial stone that contains mortar containing solidified material and has a second hard layer that covers the first hard layer and a colored layer that covers the second hard layer, and that prevents alteration or corrosion of the core material or net. And its manufacturing method have been proposed.

また、特許文献２には、雄型と雌型とからなる成型形を用意し、雌型の内側にコンクリートに対して浸透性を有する特殊塗料（無機顔料、糊料としてポリエチレンオキサイド、浸透剤としてフッ素系アルキルエステル、分散剤としてカルボキシデカノライド、増粘剤としてチタン酸カリウムを含む）を塗布し、その後、セメント、石粉、ガラス繊維、顔料を混練したコンクリートを打設し、脱型後、コンクリート製の外殻の表面から内部に向けて、０〜１５ｍｍの層厚で段階的な濃淡差を持つ色層を有した中空構造の擬石を得ることが提案されている。 In addition, in Patent Document 2, a molding formed of a male mold and a female mold is prepared, and a special coating (inorganic pigment, polyethylene oxide as a sizing agent, and a penetrating agent) having permeability to concrete inside the female mold is prepared. Fluorine-based alkyl ester, carboxydecanolide as a dispersant, containing potassium titanate as a thickener) is applied, and then cement, stone powder, glass fiber, concrete is kneaded with a pigment, after demolding, It has been proposed to obtain, from the surface of a concrete outer shell to the inside, a pseudo-stone having a hollow structure having a color layer having a gradation of gradation of 0 to 15 mm.

しかしながら、特許文献１記載の人造石においては、防水用モルタルの落下を防ぐために金網が使用されており、防水用モルタルが欠けたりすると内部の網体が腐食し、見苦しいという問題があった。また、網体の露出を防ぐために厚めの防水用モルタルを塗布する必要があった。
そして、特許文献２記載においては、確かに、打設されたコンクリートの表面に段階的な濃淡差を持つ色層を有した中空構造の擬石を得ることができるが、見た目が自然石とは異なる。また、製造された擬石の形状に凹部があると脱型できない場合があるという問題がある。 However, in the artificial stone described in Patent Document 1, a wire net is used to prevent the waterproof mortar from falling, and there is a problem that if the waterproof mortar is chipped, the internal net body is corroded and unsightly. Further, it is necessary to apply a thick waterproof mortar in order to prevent the net body from being exposed.
And in patent document 2, although it is true, it is possible to obtain a pseudo-stone with a hollow structure having a color layer having a gradation of gradation on the surface of the cast concrete, but the appearance is different from natural stone. .. In addition, there is a problem that it may not be possible to remove the mold if the manufactured pseudolite has a concave shape.

本発明はかかる事情に鑑みてなされたもので、製造が比較的簡単で自然石風な造形体の製造方法を提供することを目的とする。 The present invention has been made in view of such circumstances, and an object of the present invention is to provide a method of manufacturing a shaped body that is relatively easy to manufacture and looks like natural stone.

前記目的に沿う本発明に係る自然石風な造形体の製造方法は、設置現場に設置面積より広い穴を形成し、コンクリート、モルタル及び金属のいずれか１又は２以上から造られた、車止め又はブロックからなる造形物本体を用意して設置する第１工程と、
前記造形物本体の表面に、粒度が０を超え１ｍｍ未満の自然石の粉粒体と、水を含み水分散性で水分の蒸発によって不可逆的に硬化し硬化後は透明となる樹脂系の撥水性接着剤と、所定量の粘度調整材との混合物を吹き付けによって塗布し、前記混合物の塗布は、前記穴の中にある前記造形物本体の下部まで行い、該造形物本体の底が地中に埋まるようにする第２工程とを有する。
ここで、自然石風な造形体とは、人造石（例えば、庭石）、灯籠、車止め、ブロック、人物像、動物像等を含む。 Method for producing a natural stone-style shaped bodies according to the present invention along the objective is to form a wider bore than footprint installation site, concrete, made from any one or more of mortar及 beauty metal , also Me car stop a first step of installing are prepared shaped object body of the block,
On the surface of the shaped body, a natural stone powder having a particle size of more than 0 and less than 1 mm and a water-dispersible water-dispersible resin-based resin repellent that is irreversibly cured by evaporation of water and becomes transparent after curing. A mixture of a water-based adhesive and a predetermined amount of viscosity modifier is applied by spraying, and the mixture is applied to the lower part of the main body of the model in the hole, and the bottom of the main body of the model is underground. And a second step of filling the same.
Here, the natural stone-like shaped body includes an artificial stone (for example, a garden stone), a lantern, a car stop, a block, a human figure, an animal figure, and the like.

本発明に係る自然石風な造形体の製造方法において、粉粒体は粉、粒又は粉と粒の混合体のことをいい、これらの粒径が１ｍｍ未満であると、剥離が生じ難いという利点がある。即ち、粒度を０を超え１ｍｍ未満とする。
また、粘度調整材とは吹き付け時に粉粒体と水が分離するのを防止するために吹き付け材に混入するものである。粘度調整材（増粘材）は市販のものを使用する。 In the method for producing a natural stone-like shaped body according to the present invention, the powder or granular material refers to powder, particles or a mixture of powder and particles, and if the particle size is less than 1 mm, peeling is unlikely to occur. There are advantages. In other words, to be less than 1mm beyond the 0 the particle size.
Further, the viscosity adjusting material is mixed in the spraying material in order to prevent the powdery particles and water from being separated from each other during spraying. A commercially available product is used as the viscosity adjusting material (thickening material).

自然石の粉粒体と撥水性接着剤（硬化後透明となる）と粘度調整材との比率は、粉粒体１００重量部に対して、樹脂系の水溶性の撥水性接着剤（４０〜６０重量％が水）を８〜２０重量部、粘度調整材を１５〜３５重量部の範囲で選定するのが好ましい。これによって、自然石の粉粒体（スラリー状）の付着性が向上する。なお、１回の吹き付けによって造形物本体の地肌が隠れない場合は、複数回の吹き付けを行う。この吹き付けは、造形物本体が完全に自然石粉粒体によって隠れた時点で終了するのがよい。撥水性接着剤としては、例えば、アクリル系エマルジョン、ＥＶＡ樹脂（Ethylene Vinyl Acetate Copolymer) 等を使用できるが、他の透明接着剤であってもよい。 The ratio of natural stone powder or granular material and water-repellent bonding agent (becomes transparent after curing) and viscosity adjusting member, relative to the particulate material 100 parts by weight, the resin system of water-soluble water-repellent adhesive (40 It is preferable to select 8 to 20 parts by weight of 60% by weight of water) and 15 to 35 parts by weight of the viscosity modifier. As a result, the adhesion of the natural stone powder or granular material (slurry) is improved. In addition, when the background of the molded article body is not hidden by one-time spraying, spraying is performed a plurality of times. This spraying should be finished when the main body of the modeled object is completely hidden by the natural stone powder particles. As the water repellent adhesive, for example, an acrylic emulsion, EVA resin (Ethylene Vinyl Acetate Copolymer) or the like can be used, but other transparent adhesives may be used.

造形物本体は、設置現場で造るのが好ましいが、別場所で造られたものであってもよく、中古品であってもよい。中古品の場合は表面に苔や泥等の付着物があると吹き付け物が後日剥がれる恐れがあるので、表面に付着した異物を十分に取り除いてから、自然石の粉粒体の吹き付けを行う。
なお、自然石の粉粒体の吹き付けが完了した後に、自然石の粉粒体を含まない樹脂系の撥水性接着剤と水と粘度調整材との混合物を吹き付け、表面を硬化してもよい。 The molded article body is preferably manufactured at the installation site, but may be manufactured at another location or may be a used article. In the case of second-hand goods, if there is moss or mud on the surface, the sprayed material may peel off at a later date, so the foreign matter that has adhered to the surface should be thoroughly removed before spraying the natural stone particles.
After the spraying of the natural stone powder or granules is completed, the surface of the resin may be cured by spraying a mixture of a resin-based water-repellent adhesive containing no natural stone powder or granules, water, and a viscosity modifier. ..

本発明に係る自然石風な造形体の製造方法において、前記自然石は、人工石以外のものであれば、何でもよく、例えば、火山岩、深成岩、堆積岩、及び変成岩の１又は２以上からなるのが好ましいが、白、黄色、黒、灰色、赤、茶色等の単一の色彩のものは避けるのがより好ましい。理由は、自然石で単一の色彩のものは少なく、最終製品が自然石に見えないからである。従って、一つの岩石で複数の色の異なる成分を含むもの（例えば、御影石）等は別として、単一の色彩成分の場合は、自然石を複数用いるのが好ましい。
特に、自然石は、例えば、来待石、大理石、御影石、又は青石からなるのがよい。 In the method for producing a natural stone-like shaped body according to the present invention, the natural stone may be any one other than artificial stone, for example, one or more of volcanic rock, plutonic rock, sedimentary rock, and metamorphic rock. Is preferable, but it is more preferable to avoid a single color such as white, yellow, black, gray, red, and brown. The reason is that few natural stones have a single color and the final product does not look like natural stone. Therefore, in the case of a single color component, it is preferable to use a plurality of natural stones, apart from one rock containing a plurality of different color components (for example, granite).
In particular, the natural stone may be made of Kimachi stone, marble, granite, or blue stone, for example.

本発明に係る自然石風な造形体の製造方法において、前記造形物本体の内部に発泡プラスチックの充填物が納められて、軽量化されているのが好ましいが、必須の要件ではない。現場又は別場所で、コンクリートによって造形物本体を製造する場合は、内部に補強用の鉄筋、プラスチック、木材等を入れることもできる。 The method of manufacturing a natural stone-style shaped bodies according to the present invention, the molded product packing foamed plastics therein housed in the body, but preferably is lighter, not essential. When the main body of the modeled article is manufactured using concrete at the site or at another place, reinforcing steel, plastic, wood, etc. for reinforcement can be put inside.

また、本発明に係る自然石風な造形体の製造方法において、前記コンクリート又は前記モルタルに、発泡軽量材が使用されているのが好ましいが、この場合は、造形物本体を分解できる型枠に入れて構築するのが好ましい。 Further, in the method for producing a natural stone-like shaped body according to the present invention, the concrete or the mortar, it is preferable that a lightweight foam material is used, in this case, in the mold that can disassemble the molded body It is preferable to put and construct.

自然石風な造形体が、コンクリート、モルタル、樹脂、木及び金属のいずれか１又は２以上からなる造形物本体の表面に自然石の粉粒体と樹脂系の透明撥水性接着剤とを含む混合物層が１〜５ｍｍの厚みで形成されている場合、内部の造形物本体の地肌は隠れることになる。自然石の粉粒体は１．２ｍｍ（好ましくは１ｍｍ）アンダーとなっている。なお、コンクリートに顔料を入れて着色し、混合物を薄く塗布して、内部のコンクリートの色彩と、混合物層との色彩を交じり合わせることもできる。なお、前記自然石の粉粒体は、粒度が０を超え１．２ｍｍ未満の御影石、大理石、来待石、又は青石であるのが好ましい。 A natural stone-like shaped body contains a natural stone powder and a resin-based transparent water-repellent adhesive on the surface of a shaped body consisting of one or more of concrete, mortar, resin, wood and metal. When the mixture layer is formed to have a thickness of 1 to 5 mm, the background of the inside of the molded article body is hidden. The natural stone powder is 1.2 mm (preferably 1 mm) under. It is also possible to put a pigment in concrete to color it, apply a thin mixture thereof, and mix the color of the concrete inside and the color of the mixture layer. The natural stone powder and granules are preferably granite, marble, Kimachi stone, or blue stone having a particle size of more than 0 and less than 1.2 mm.

本発明に係る自然石風な造形体の製造方法においては、コンクリート、モルタル及び金属のいずれか１又は２以上を用いて造形物本体を作り、その表面に粉粒体状の自然石を透明な撥水性接着剤を用いて接合するので、自然石風な造形体とすることができる。
これらの材料は安価であると共に、自由に形を変えることができるので、比較的簡単に自然石風な造形体を製造できる。
特に、自然石の粉粒体の粒度を１ｍｍ未満としたので、造形物本体への付着性がよい。 In the production method of a natural stone-style shaped bodies according to the present invention, concrete, create a shaped material body with one or more any of mortar及 beauty metals, the powder or granular material like natural stone on the surface Since the transparent water-repellent adhesive is used for bonding, a natural stone-like shaped object can be obtained.
Since these materials are inexpensive and can be freely changed in shape, a natural stone-like shaped body can be manufactured relatively easily.
In particular, the particle size of the granular material of natural stone since less than 1 mm, good adhesion to molding material body.

図１を参照しながら、本発明の第１の実施の形態に係る自然石風な造形体の製造方法について説明する。
まず、設置しようとする地面（設置現場）１１を例えば２０〜５０ｃｍの深さに掘り下げて穴１２を形成する。穴１２の広さは自然石風な造形体の一例である人造石（例えば、庭石）１０の設置面積より広く、人造石１０の周囲に例えば５〜２０ｃｍ程度の空間ができるようにする。これは、例えば、コンクリートからなる造形物本体１３の底が完全に地中に埋まって倒壊等の危険を防止すると共に、造形物本体１３の下部まで、自然石（例えば、御影石）の粉粒体と水溶性樹脂と粘度調整材（増粘材）の混合物Ａの吹き付けができるようにするためである。 A method of manufacturing a natural stone-like shaped body according to the first embodiment of the present invention will be described with reference to FIG. 1.
First, the ground (installation site) 11 to be installed is dug down to a depth of, for example, 20 to 50 cm to form a hole 12. The size of the hole 12 is wider than the installation area of the artificial stone (for example, garden stone) 10 which is an example of a natural stone-like shaped body, and a space of, for example, about 5 to 20 cm is formed around the artificial stone 10. This is because, for example, the bottom of the model body 13 made of concrete is completely buried in the ground to prevent the risk of collapse and the like, and up to the lower part of the model body 13, natural stone (for example, granite) powder or granular material. This is because the mixture A of the water-soluble resin and the viscosity adjusting material (thickening material) can be sprayed.

次に、この穴１２の中に適当量の捨て石１８を入れ、コンクリートを捨て石１８が隠れる程度流した後、コンクリートによって外観が自然石風の造形物本体１３を構築する。この場合、造形物本体１３を構築するコンクリートは多少水の量を減らして流動性を無くし、必要に応じて形態を整える。
なお、図２に示す本発明の第２の実施の形態に係る自然石風な造形体の製造方法のように、造形物本体１３の内部に支持部材１４を配置することもできる。支持部材１４としては、例えば、鉄筋、木材、プラスチック等があり、図２では、木材１５の周囲に釘１６を打って打設されたコンクリートの形状を保つようにしているが、型枠を用いて造形物本体を保持するようにしてもよい。型枠は硬質プラスチック又は金属（例えば、鉄）を用いて製作するのがよい。 Next, an appropriate amount of waste stone 18 is put into the hole 12, concrete is poured to such an extent that the waste stone 18 is hidden, and then a concrete body 13 having a natural stone appearance is constructed by the concrete. In this case, the concrete for constructing the molded article body 13 is made to have a certain amount of water to eliminate fluidity, and the shape is adjusted as necessary.
Note that the support member 14 may be arranged inside the molded article body 13 as in the method of manufacturing a natural stone-like molded body according to the second embodiment of the present invention shown in FIG. The support member 14 may be, for example, a reinforcing bar, wood, plastic, or the like. In FIG. 2, a nail 16 is struck around the wood 15 to keep the shape of the concrete placed, but a form is used. You may make it hold|maintain the molded article main body. The formwork may be made of hard plastic or metal (eg, iron).

コンクリートが固化した造形物本体１３の周囲（表面）に、自然石の粉粒体と、水を含み水分散性で水分の蒸発によって不可逆的に硬化し硬化後は透明となる樹脂（撥水性接着剤）であるアクリル系エマルジョン（又は、ＥＶＡ樹脂）と、市販の粘度調整材との混合物Ａを、圧縮空気を用いた吹き付けによって塗布して混合物層を形成する。この場合の、自然石の粉粒体、水を含む樹脂、及び粘度調整材との混合比は、１００：８〜２０：１５〜３０とするのが好ましいが、自然石の粉粒体を造形物本体１３に固定できる混合比であればよいし、樹脂の種類によってもこれらの配分は変わる。
混合物Ａから水分が蒸発すると、樹脂が固化して透明となり、その後、水に触れても樹脂は溶けない。なお、混合物の吹き付けは複数回に分けて行ってもよいし、最終工程で透明な樹脂と水と粘度調整材との混合物のみを吹き付けてもよい。混合物層の厚みは１〜５ｍｍとするのがよく、薄いと粒が露出し、厚いと外観が悪くなる。 Around the surface (surface) of the molded article body 13 in which concrete is solidified, natural stone powder particles and water dispersible water-dispersible resin that is irreversibly cured by evaporation of water and becomes transparent after curing (water-repellent adhesion A mixture A of an acrylic emulsion (or EVA resin) which is an agent) and a commercially available viscosity adjusting material is applied by spraying with compressed air to form a mixture layer. In this case, the mixing ratio of the natural stone powder, the resin containing water, and the viscosity adjusting material is preferably 100:8 to 20:15 to 30, but the natural stone powder is formed. Any mixing ratio that can be fixed to the object body 13 may be used, and the distribution of these changes depending on the type of resin.
When water evaporates from the mixture A, the resin solidifies and becomes transparent, and the resin does not dissolve even if it is subsequently contacted with water. The mixture may be sprayed in plural times, or only the mixture of the transparent resin, water and the viscosity adjusting agent may be sprayed in the final step. The thickness of the mixture layer is preferably 1 to 5 mm, and when it is thin, the particles are exposed, and when it is thick, the appearance is deteriorated.

自然石としては、来待石、青石、御影石、又は大理石を使用するのが好ましいが、その他の天然石であってもよい。石粉は粉砕後、最終的には開度（オープニング）が１ｍｍの篩を通して、１ｍｍ以上の粒体を除いている。これは１ｍｍ以上の粒が存在すると、製品である自然石風な造形体から剥がれ易いからである。なお、石粉（粉粒体）は自然石を破砕したものでもよいが、自然の砂や石粉を用いることもできる。篩のオープニングは、前記実施の形態では１ｍｍであったが、１．２ｍｍとすることもできる。粉粒体の粒度が大きいと造形物本体への付着が悪くなる。 As the natural stone, it is preferable to use Kimachi stone, blue stone, granite stone, or marble, but other natural stones may be used. After the stone powder is crushed, it is finally passed through a sieve having an opening (opening) of 1 mm to remove particles of 1 mm or more. This is because the presence of particles of 1 mm or more is likely to cause peeling from the natural stone-like shaped body that is the product. The stone powder (powder) may be natural stone crushed, but natural sand or stone powder may also be used. Although the opening of the screen was 1 mm in the above-mentioned embodiment, it can be 1.2 mm. If the particle size of the granules is large, the adherence to the main body of the molded article becomes poor.

なお、粉粒体の粒度が大きい場合、又は箔状の粉粒体を有する場合は、仮に粉粒体の粒度が１ｍｍ以上であっても、接着剤の量を増やす、又は複数回の塗布を行う、あるいは仕上げで水を加えた接着剤のみを塗布して、表面にコーティング層を形成する等の方法を用いて対応できる。
混合物Ａの塗布は、穴１２の中にある造形物本体１３の下部まで行う。これによって、造形体である人造石１０の外観を完全に自然石風とすることができる。
塗布する。 If the particle size of the particle is large, or if the particle has a foil-like particle, even if the particle size of the particle is 1 mm or more, increase the amount of the adhesive or apply the adhesive multiple times. It is possible to deal with this by using a method of forming a coating layer on the surface by applying only an adhesive to which water is added or finishing is applied.
The application of the mixture A is performed up to the lower part of the model body 13 in the hole 12. As a result, the appearance of the artificial stone 10, which is a molded body, can be made to look like a natural stone.
Apply.

続いて、図３に示す自然石風な造形体の一例である灯籠２０の製造方法について説明する。予めコンクリートで製造された造形物本体である灯籠本体２１を用意する。灯籠本体２１（灯籠２０も同じ）は、上下方向に分けると、脚部２２、台部２３、灯収納部２４、及び屋根部２５を有している。
これらは、金属、木又はプラスチック製の型枠を用いて製造される。灯籠本体２１はコンクリートで製造するので、一体的に造るのが好ましいが通常の石材で造るように、部分毎に作り、積み重ねてもよい。灯籠本体２１を分割して製造する場合は、各部の合わせ面に凸部と凹部からなる印籠部を設けておくことによって、組み立てが容易に行え、しかも従来の組み立て式の石灯籠よりも安全性が増す。 Subsequently, a method of manufacturing the lantern 20 which is an example of the natural stone-like shaped body shown in FIG. 3 will be described. A lantern body 21, which is a molded body made of concrete in advance, is prepared. The lantern body 21 (same for the lantern 20) has a leg portion 22, a base portion 23, a lamp storage portion 24, and a roof portion 25 when divided in the vertical direction.
These are manufactured using metal, wood or plastic formwork. Since the lantern body 21 is made of concrete, it is preferable to make the lantern body 21 integrally, but it is also possible to make and stack each part like an ordinary stone material. If the lantern body 21 is manufactured separately, it is easier to assemble by providing the indentation part consisting of the convex part and the concave part on the mating surface of each part, and more safety than the conventional assembly type stone lantern. Will increase.

灯籠本体２１をコンクリートで一体的に造ると、重量物となるので、１）内部に中空体を形成する、２）内部に発泡プラスチック等を入れる、２）発泡軽量コンクリート（発泡軽量材）を用いて造る等の方法によって軽量化することができる。
なお、灯籠本体２１の内部に支持部材（鉄等の金属、プラスチック）を入れて補強することは当然できる。 If the lantern body 21 is integrally made of concrete, it becomes a heavy object. Therefore, 1) a hollow body is formed inside, 2) foamed plastic is put inside, and 2) foamed lightweight concrete (foamed lightweight material) is used. The weight can be reduced by a method such as manufacturing.
It should be noted that it is naturally possible to put a supporting member (metal such as iron or plastic) inside the lantern body 21 for reinforcement.

灯籠本体２１の周囲に、自然石の粉粒体と、水を含み水分散性で水分の蒸発によって不可逆的に硬化し硬化後は透明となる樹脂（撥水性接着剤）であるアクリル系エマルジョン（又は、ＥＶＡ樹脂）と、粘度調整材との混合物Ａを、圧縮空気を用いた吹き付けによって塗布する。この場合の、自然石の粉粒体、樹脂、粘度調整材との混合比は、１００：１〜１０：５〜２０とするのが好ましいが、自然石の粉粒体を灯籠本体２１に固定できる混合比であればよいし、樹脂の種類によっても、これらの配分は変わる。 Around the lantern body 21, a natural stone powder and an acrylic emulsion (water-repellent adhesive) that is water-dispersible and water-dispersible and irreversibly cured by evaporation of water and becomes transparent after curing ( Alternatively, a mixture A of EVA resin) and a viscosity adjusting material is applied by spraying using compressed air. In this case, the mixing ratio of the natural stone powder, the resin, and the viscosity adjusting material is preferably 100:1 to 10:5 to 20, but the natural stone powder is fixed to the lantern body 21. Any mixing ratio can be used, and the distribution of these changes depending on the type of resin.

灯籠本体２１をコンクリートで製造する場合は、形状は自由に変えられるので、脚部２２の下に台座部２６を設けることもできる。これによって、灯籠２０の安定性が増し、台座部２６を地中に位置させることによって、通常の石灯籠と変わらない外観となる。 When the lantern body 21 is made of concrete, the shape can be freely changed, so that the pedestal portion 26 can be provided below the leg portions 22. This increases the stability of the lantern 20 and by positioning the pedestal portion 26 in the ground, the appearance is the same as a normal stone lantern.

本発明に係る自然石風な造形体の製造方法を用いて、例えば、自然石風な石（庭石）のみでなく、自然石風な車止め、自然石風のブロック、自然石風な塀を構築することができる。更に、人の像、動物像、城の石垣、人家の石垣等も形成できる。城の石垣、人家の石垣はコンクリートで石垣模様のパネルを造り、その表面を自然石の粉粒体と樹脂と粘度調整材との混合物で覆うことになる。
本発明は、前記実施の形態のみに限定されず、前記実施の形態を組み合わせて自然石風な造形体を構築する場合も適用される。
前記実施の形態は、造形物本体をコンクリートで構成したが、モルタル、樹脂、木及び金属のいずれか１又は２以上（コンクリートを含む）から、外観が自然石風の造形物本体を造ることもできる。 Using the natural stone-like shaped object manufacturing method according to the present invention, for example, not only natural stone-like stones (garden stones) but also natural stone-like bollards, natural stone-like blocks, and natural stone-like fences are constructed. can do. Furthermore, it is possible to form statues of people, animals, stone walls of castles, stone walls of houses, etc. Stone walls of castles and stone walls of houses are made of concrete with a stone wall pattern panel, and the surface is covered with a mixture of natural stone powder, resin, and viscosity modifier.
