본 발명은 시멘트와 자갈등의 건축재를 재료로 하고 시멘트 경화지연재의 특성을 이용하여 제품의 두께, 형태에 관계없이 원하는 형상의 미려한 세척콘크리트제품을 손쉽게 얻을 수 있는 세척 콘크리트의 제품의 제조방법에 관한 것이다.The present invention is a method of manufacturing a concrete product using a building material such as cement and gravel and using a characteristic of the cement hardening delay material to easily obtain a beautiful washing concrete product of a desired shape regardless of the thickness and shape of the product. It is about.

통상적인 종래의 건축재료, 실내장식품이나 기타 물품등에 있어서는 다양한 재료를 사용하여 제작하여 왔으나, 시멘트나 콘크리트를 사용하여 제작하는 물품의 경우에는 별도의 시멘트 분말을 사용하여 인공콘크리트를 제조하는 방법이 있었으나 이는 제품의 두께가 두꺼울 경우라든가 곡면의 제품에는 표면이 균등하지 못하는 등의 결점이 있었으므로 본 발명은 종래와는 달리 필요한 크기나 각종형상의 건축재나 물품을 자연석이나 자갈 등의 천연재료가 갖는 표면의 질감을 충분히 나타낼 수 있고, 시공이 간편하게 행하여질 수 있도록 한 세척콘크리트제품의 제조방법에 그 목적이 있다.Conventional building materials, interior decoration or other items have been produced using a variety of materials, but in the case of articles manufactured using cement or concrete, there was a method of manufacturing artificial concrete using a separate cement powder This is because the thickness of the product or the curved surface of the product has a defect such as the surface is not uniform, the present invention, unlike the prior art, the surface having a natural material such as natural stone, gravel, etc. The purpose of the present invention is a method for producing a washing concrete product that can sufficiently express the texture of the product and can be easily performed.

본 발명은 이러한 목적을 구체화 하기 위하여 만들고자 하는 물품형상의 금형내 표면에 시멘트 경화지연제를 애상으로 직접 도포하거나 페이퍼로 된 시멘트 경화지연제를 삽입하여 시멘트나 자갈 등의 천연석재가 혼합된 콘크리트를 주입시킨 다음 금형에 진동을 주어 콘크리트를 다진후 판재로 눌러 일정한 시간동안 양생시킨 후 금형을 분리제거하고 양생된 콘크리트반제품의 표면에 침투된 시멘트 경화지연제에 의하여 양생이 이루어지지 아니한 시멘트를 세척기를 이용하여 물로 씻어내어 자갈등의 천연재형상이 일부 돌출되도록 하여 완성시킴으로서 천연재가 갖는 본래의 질감을 나타낼수 있는 제품, 예를 들면 건축물의 계단, 보도블록, 꽃병, 실내장식용판재, 화단 등에 적용할 수 있는 세척콘크리트제품을 제조할 수 있는 것이다.In order to achieve the above object, the present invention provides concrete mixed with natural stones such as cement or gravel by directly applying a cement curing retardant to the surface of a mold in the shape of an article to be made as a frost or by inserting a paper cement curing retardant. After the injection, the mold is vibrated to crush concrete and then pressed with a plate to cure for a certain time.The mold is separated and removed and the cement that is not cured by the cement curing retardant penetrated to the surface of the cured concrete semi-finished product is washed. It can be applied to products that can exhibit the original texture of natural materials such as stairs, sidewalk blocks, vases, interior decoration boards, flower beds, etc. Will be able to manufacture a concrete product that can be washed.

다음은 본 발명의 세척콘크리트의 제조방법에 대하여 첨부된 도면을 참조하여 상세히 살펴보고자 한다.Next will be described in detail with reference to the accompanying drawings for the manufacturing method of the washing concrete of the present invention.

[제조실시예]Production Example

[1단계][Stage 1]

제2도 I에 도시한 바와같이 우선 만들고자 하는 형상, 이를테면 사각꽃병의 금형(1)을 제작준비하고 시멘트와 미리 표면을 깨끗하게 물로 씻거나 닦아낸 고운자갈이나 천연석 또는 인조석에 물을 가하여 이들을 혼합시켜 제조된 콘크리트(3)을 준비한다.As shown in FIG. 2, first, a mold (1) of a square flower vase, which is to be made, is prepared and prepared by mixing water with fine gravel or natural stone or artificial stone, which has been washed or wiped with cement and the surface beforehand Prepared concrete 3 is prepared.

[2단계][Step 2]

제2도의 II에 도시한 바와같이 금형(1)의 내측면에 액상으로된 시멘트 경화제(2)를 도포하거나 종이상의 시멘트 경화지연제(2)를 삽입부착시킨다. 이때 시멘트 경화지연제(2)를 도포하는 경우는 곡면 및 각형에 모두 사용할 수 있고 종이는 각형에 사용기가 용이하다.As shown in II of FIG. 2, a cement hardener 2 in a liquid phase is applied to the inner surface of the mold 1, or a paper cement hardener 2 is inserted and attached. In this case, when the cement hardening retardant (2) is applied, both the curved surface and the square can be used, and the paper is easy to use for the square.

[3단계][Step 3]

제2도의 III에 도시한 바와같이 상기 2단계에서 준비된 경화지연제(2)가 도포 또는 삽입된 금형(I)내에 1단계에서 준비한 콘크리트(3)를 균등하게 분배하여 채워 넣는다.As shown in III of FIG. 2, the concrete 3 prepared in step 1 is equally distributed and filled into the mold I to which the curing retardant 2 prepared in step 2 is applied or inserted.

[4단계][Step 4]

제2도의 IV에 도시한 바와같이 통상의 진동기구(4)를 이용하여 금형(1)에 진동을 주어 금형(1)내에 콘크리트(3)가 잘 다져지도록 하고 상부에 판재(5)등으로 눌러 덮어 놓는다.As shown in IV of FIG. 2, the mold 1 is vibrated using a conventional vibrating mechanism 4 so that the concrete 3 is well compacted in the mold 1 and pressed with a plate 5 on the top. Cover it.

[5단계][Step 5]

제2도의 V에 도시한 바와같이 적당한 시간동안 콘크리트를 양생시킨다. 이때 콘크리트의 두께에 따라 양생시간은 차이가 있으나, 대략 8-72시간 동안 콘크리트(3)을 양생시키며 양생시 외부에서 충격을 가하면 파손의 위험이 있으므로 격리된 장소에서 이를 행함이 바람직하다.As shown in V of FIG. 2, the concrete is cured for a suitable time. At this time, the curing time is different depending on the thickness of the concrete, but curing the concrete (3) for about 8-72 hours, if the impact from the outside during curing there is a risk of breakage it is preferable to do this in an isolated place.

[6단계][Step 6]

제2도의 VI에 도시한 바와 같이 금형(1)을 물품의 형상에 따라 상하분리, 좌우분리 또른 상하, 좌우분리 시키고 경화지연제(2)가 함유된 종이를 사용할 경우엔 종이를 제거하여 콘크리트반제품(3')을 얻는다.As shown in VI of FIG. 2, the mold 1 is divided up and down, left and right, up and down, left and right according to the shape of the article, and when using a paper containing a curing retarder (2), the paper is removed to remove the concrete. Get 3 '.

[7단계][Step 7]

제2도의 VII에 도시한 바와같이 상기6단계의 콘크리트반제품을 미도시된 세척기를 이용하여 시멘트 경화지연제(2)가 침투된 표면을 강하게 물로 분사시킴으로서 시멘트 경화지연제(2)의 특성에 의하여 양생이 이루어지지 아니한 표면부위의 시멘트를 깨끗하게 씻어내어 표면에 위치한 자갈이나 천연석 또는 인조석의 충분한 질감이 표출될 수 있게한후, 일정한 시간 건조하면 세척콘크리트제품(제2도의 VIII)(6)을 얻는다.As shown in VII of FIG. 2, the semi-concrete semi-finished product of step 6 is sprayed with water using a washing machine (not shown) to strongly infiltrate the surface into which the cement hardening retardant 2 penetrates. The cement on the uncured surface area is washed off cleanly so that sufficient texture of gravel, natural stone or artificial stone on the surface can be expressed, and then dried for a certain time to obtain washed concrete product (VIII of Fig. 2). .

이와같이 제조된 세척콘크리트제품(6)은 한가지 예시에 불과한 것으로서, 제3도에 도시한 바와같이 그 형태나 모양은 얼마든지 변형이 가능하고 실제로 포장용 판석보도, 혼합식의 블록, 계단, 꽃병 등 여러가지 장식품 내지는 건축물 등에 다양하게 이용할 수 있다.The washed concrete product 6 manufactured as described above is just one example, and as shown in FIG. 3, its shape and shape can be modified as much as possible, and in fact, various paving flags, mixed blocks, stairs, vases, etc. It can be used in various ways, such as an ornament or a building.

따라서 본 발명은 필요한 두께가 각종 형상으로된 건축재 등의 물품에 자연석이나 자갈 등의 천연재료가 갖는 표면, 질감을 충분히 나타낼 수 있고 시공이 간편하게 행하여질 수 있으며 건축물 또는 여러가지 장식품등에 천연재가 갖는 본래의 질감을 나타낼 수 있어 심미감과 우아함을 주는 등 우수한 효과가 있는 것이다.Therefore, the present invention can sufficiently represent the surface and texture of natural materials such as natural stone or gravel on articles such as building materials having various thicknesses, and construction can be easily performed. It can show texture, giving it an aesthetic and elegant effect.
