본 발명은 블록의 제조방법에 관한 것으로서, 좀 더 상세히는 간단한 공정에 의해 자연석이 매입 부착되어 돌출된 콘크리트블록을 제조하되, 제조된 블록이 미려하고 입체적인 자연미를 가지는 자연석블록의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a block, and more particularly, to produce a concrete block protruding by attaching natural stone embedded by a simple process, and relates to a method for producing a natural stone block having a beautiful and three-dimensional natural beauty of the produced block. .
자연석을 이용한 벽면 등의 시공방법으로서, 모르타르를 이용하여 자연석을 쌓아 올리는 방법은 작업자의 숙련을 요하며, 현장작업에 의존하므로 시공의 능률화를 기하기 어렵고, 구조적으로나 외관상으로 바람직스럽지 못한 경우가 많다. 따라서, 근래에는 자연석을 매입하여 돌출시킨 콘크리트블록을 미리 대량생산하고, 현장에서 이를 조적하여 간단히 시공을 완료하는 방법이 제안되고 있다. 이러한 자연석블록의 시공방법은 형틀 위에 여러 가지 형태의 자연석을 적절히 배치하고, 자연석의 사이에 이형재로서 용융된 파라핀왁스나 모래를 주입한 후, 모르타르나 콘크리트를 타설하여 양생시킨 후, 형틀을 분리하고, 이형재인 파라핀이나 모래를 제거함으로써, 자연석이 매입돌출된 블록을 완성하게 된다.As a construction method of natural wall, etc., the method of stacking natural stone using mortar requires the skill of the worker and it is difficult to streamline the construction because it depends on the field work, and it is often undesirable in terms of structure and appearance. . Therefore, in recent years, a method of mass-producing a concrete block protruding by purchasing natural stone in advance and structuring it in the field has been proposed to simply complete the construction. In the construction method of natural stone block, various types of natural stone are properly placed on the mold, molten paraffin wax or sand is injected as a release material between the natural stones, and after curing by pouring mortar or concrete, the mold is separated. By removing paraffin or sand, which is a release material, a natural stone embedded block is completed.
그런데, 파라핀을 이형재로 사용하는 경우에는 파라핀의 완전한 제거가 곤란하여, 파라핀이 자연석의 틈새나 오목한 부분에 잔존하게 되고, 잔존 파라핀을 토오치로 녹여내는 번거로운 후속공정을 실시하더라도 끄을음이 발생하여 블록의 미관이 손상되는 등의 문제점이 있다. 또한, 모래를 이형재로 사용하는 경우에는 모르타르나 콘크리트의 시멘트페이스트가 모래 속에 침투하여 경화되므로, 이형재인 모래가 자연석에 부착된 채로 경화되어, 원하는 바와 같은 깨끗한 표면이나 질감이 노출되지 못하게 된다.However, in the case of using paraffin as a release material, it is difficult to completely remove the paraffins, and paraffins remain in the gaps or recesses of natural stones, and even after performing a cumbersome subsequent process of melting the remaining paraffins with torch, There is a problem such that the aesthetics of the block is damaged. In addition, when sand is used as a release material, the mortar or the cement paste of concrete penetrates into the sand and hardens, so that the sand, which is a release material, is hardened while being attached to natural stone, thereby preventing a clean surface or texture as desired.
또한, 종래의 자연석블록은 모든 자연석이 형틀의 저면에 맞닿도록 배열된 상태에서 경화되므로, 자연석의 돌출정도가 모두 일정하여 자연스런 입체감이 부족하다는 문제점이 있다.In addition, the conventional natural stone block is cured in a state in which all the natural stones are arranged in contact with the bottom of the mold, there is a problem in that the degree of protrusion of the natural stones are all constant, there is a lack of natural three-dimensional feeling.
본 발명은 전술한 바와 같은 종래의 자연석블록의 제조상의 문제점에 착안하여 제안된 것으로서, 매입돌출되는 자연석의 노출면이 깨끗하고 미려하게 처리될 수 있는 새로운 방법의 자연석블록의 제조방법을 제공하고자 하는 것이다.The present invention has been proposed in view of the problems of the conventional natural stone block as described above, to provide a method of manufacturing a natural stone block of a new method that can be treated clean and beautifully exposed surface of the natural stone to be protruded will be.

이하에서, 도면을 참조하여 본 고안의 바람직한 실시예를 설명한다. 제1도는 본 발명의 일실시예에 따른 자연석블록의 제조방법의 순서를 설명하는 도면으로서, 도시된 바와 같이, 형틀(1)의 저면에 적절한 크기의 자연석(2)을 배열한다(a공정). 이어서, 자연석(2)의 주위에 모래층(3)을 소정높이로 깐다(b공정). 이 때, 모래층(3)의 높이는 자연석(1)의 요철이 잘 드러날 수 있는 정도의 높이로 하되, 모래층(3)의 상면은 자연스럽게 불규칙한 표면으로 형성하는 것이 바람직하다.Hereinafter, with reference to the drawings will be described a preferred embodiment of the present invention. FIG. 1 is a view illustrating a procedure of a method of manufacturing a natural stone block according to an embodiment of the present invention. As shown in FIG. 1, natural stone 2 having an appropriate size is arranged on the bottom of the mold 1 (step a). . Subsequently, the sand layer 3 is covered by the predetermined height around the natural stone 2 (b process). At this time, the height of the sand layer 3 is such that the height of the unevenness of the natural stone (1) is well exposed, it is preferable that the upper surface of the sand layer 3 is naturally formed as an irregular surface.
그리고 모래는 자연석(2) 주위에 골고루 침투하도록 마른 모래를 사용하는 것이 바람직하며, 모래를 깐 후에는, 물을 부어 모래를 적심으로써 후술하는 석고층(4)이 모래 속으로 침투하는 것을 효과적으로 방지할 수 있다. 이어서, 모래층(3) 위에 물에 갠 석고를 주입하여 석고층(4)을 형성한다(c공정). 석고층(4)은 치밀하여 시멘트페이스트가 침투하지 못하도록 모래층(3)과 후술하는 모르타르 또는 콘크리트(6)를 차단하는 기능을 하며, 경화속도가 빠르고, 분리제거가 용이하다는 장점을 가진다. 석고를 대신하여 백회 등과 같은 대체재료가 사용될 수도 있다. 석고층(4)이 적절히 경화되면 그 위에 적절한 크기의 돌가루(5)를 산포한다(d공정). 이 돌가루(5)는 모르타르나 콘크리트블록을 은폐하고 시각적 효과를 높이며, 석고층(4)의 분리를 돕는 역할을 한다. 경우에 따라 돌가루(5)는 생략될 수 있다. 이어서, 블록제조용 모르타르나 콘크리트(6)를 형틀에 주입하고 경화시킨다(e공정).And it is preferable to use dry sand so that the sand evenly penetrates around the natural stone (2), and after the sand is applied, water is poured into the sand to effectively prevent the gypsum layer (4) described later from penetrating into the sand. can do. Subsequently, the gypsum ground is injected into the sand layer 3 to form a gypsum layer 4 (step c). The gypsum layer 4 has a function of blocking the sand layer 3 and the mortar or concrete 6 to be described later so that the cement paste does not penetrate and has the advantage of fast curing speed and easy separation and removal. Instead of gypsum, alternative materials such as white ash may be used. When the gypsum layer 4 is properly cured, the powder 5 of appropriate size is dispersed thereon (d step). This stone (5) serves to conceal mortar or concrete blocks, increase the visual effect, and help the separation of the plaster layer (4). In some cases, the powder 5 may be omitted. Next, the mortar or concrete 6 for block manufacture is inject | poured into a mold, and it hardens | cures (e process).
제2도는 본 발명의 다른 실시예에 따른 제조공정도로서, 형틀(1)의 저면에 자연석(2)을 배열하고(a공정), 자연석 주위에 모래층(3)을 깔고(b공정), 물에 갠 석고를 주입하여 석고층(4)을 경화시키는 공정(c공정) 까지는 전술한 공정과 동일하나, 돌가루(5)를 주입하기(d공정) 전에, 다시 석고층(4) 위에 재차 자연서(2')을 배열하고(a'공정), 자연석(2') 주위에 모래(3')를 깔고(b'공정), 그 위에 석고층(4')을 형성하는 단계(c'공정)가 부가된다. 이러한 부가공정은 또다시 반복될 수도 있다. 이어서, 모르타르나 콘크리트(6)를 주입하여 경화시킨다. 블록이 경화된 후 형틀(1)을 제거하면, 제3도에서 예시한 바와 같은 자연석블록이 완성되게 된다.2 is a manufacturing process diagram according to another embodiment of the present invention, in which the natural stone 2 is arranged on the bottom surface of the mold 1 (a step), the sand layer 3 is laid around the natural stone (b step), and immersed in water. The process up to the step (c) of curing the gypsum layer 4 by injecting gypsum is the same as the above-described step, but before the injection of the stone powder 5 (d step), the natural text is again placed on the gypsum layer 4 ( 2 ') (a' process), sand (3 ') around natural stone (2') (b 'process), and forming gypsum layer (4') thereon (c 'process) Is added. This addition process may be repeated again. Next, mortar or concrete 6 is injected and hardened. When the mold 1 is removed after the block is cured, the natural stone block as illustrated in FIG. 3 is completed.
이상에서 설명한 본 발명에 따르면, 이형재인 모래와 블록성형재료인 모르타르 또는 콘크리트가 석고층에 의해 완전히 차단, 분리되므로 모르타르나 콘크리트의 시멘트페이스트가 이형재인 모래쪽으로 침투하지 못하므로, 자연석의 요철면이 원래의 형태대로 드러나서 자연석의 질감을 충실히 표현할 수 있다. 또한, 석고층을 이용하여 자연석을 2단 또는 그 이상으로 배열함으로써, 자연석의 돌출정도에 변화를 주어 더욱 입체적이고 자연스러운 자연석블록을 제조할 수 있다.According to the present invention described above, since the sand of the release material and the mortar or concrete of the block molding material is completely blocked and separated by the gypsum layer, the cement paste of the mortar or concrete does not penetrate into the sand of the release material, so that the uneven surface of the natural stone It can be revealed in its original form to faithfully express the texture of natural stone. In addition, by arranging the natural stone in two or more stages using the gypsum layer, it is possible to produce a more three-dimensional and natural natural stone block by varying the degree of protrusion of the natural stone.
