Description

자연석을 이용한 블록 및 그 제조방법{Block using natural stone and manufacturing method thereof}Block using natural stone and its manufacturing method

본 발명은 자연석을 이용한 블록 및 그 제조방법에 관한 것으로서, 보다 상세하게는 자연석이 양 측면에 부착되고 내측에는 구멍이 형성된 자연석을 이용한 블록 및 그 제조방법에 관한 것이다.The present invention relates to a block using a natural stone and a method for manufacturing the same, and more particularly, to a block using a natural stone attached to both sides and a hole formed in the inner side and a manufacturing method thereof.

일반적으로 블록은 시멘트와 모래 그리고 물을 일정 비율로 적절하게 혼합시킨 후, 그 혼합물을 금형 내에 부어서 양생시킨 후 제조하게 된다.In general, blocks are prepared by properly mixing cement, sand and water in a proportion, and then pouring the mixture into a mold and curing the mixture.

그러나, 이와 같은 블록은 그 구조가 단순하고 외부로부터 가해지는 충격 등에 의해 쉽게 파손됨으로써 수명이 단축되고, 외관이 일률적으로 형성되어 미려하지 않으며, 자연 친화적이지 못할 뿐만 아니라 조적시 강도가 저하되는 등의 여러 가지 문제점들이 내재되어 있었다.However, such a block has a simple structure and is easily broken by an impact from the outside, thereby shortening its lifespan, uniformly forming its appearance, not being beautiful, not being friendly to nature, and degrading its strength when applied. Several problems were inherent.

그래서, 종래에도 도 1 에 도시한 바와 같이 자연석을 이용한 블록을 제조하는 방법이 제안되고 있다.Therefore, conventionally, as shown in FIG. 1, the method of manufacturing the block using a natural stone is proposed.

이는 바닥판(10)의 상측에 금형(11)을 위치시키고, 상기 금형(11)의 내측에 자연석(12)을 안착시킨 후 그 사이에 적정량의 모래(13)를 뿌린 후 상측에 모르타르(14)를 충전하고 상부에서 밀판(15)이 유압에 의해 하강하도록 하여 블록을 성형한 후 금형(11)을 분리하고 모래(13)를 제거토록 하여 블록을 제조하게 된다.This is to place the mold 11 on the upper side of the bottom plate 10, the natural stone 12 is seated inside the mold 11, and after spraying an appropriate amount of sand 13 therebetween, the mortar (14) ) To form a block by lowering the pressure plate (15) by the hydraulic pressure at the top and then to separate the mold (11) and to remove the sand (13) to manufacture the block.

그러나, 이와 같은 종래 블록의 제조방법은 블록의 일측면에만 자연석이 부착됨으로써 담장 등에는 시공할 수 없고, 자연석을 원하는 위치에 부착시키는 것이 어려우며, 제조된 블록이 구멍을 형성하기 어려워 조적시 강성이 저하되는 등의 여러 가지 문제점들이 내재되어 있었다.However, in the conventional method of manufacturing a block, natural stone is attached to only one side of the block, so that it cannot be installed on a fence, etc. Various problems were inherent, such as deterioration.

따라서, 본 발명은 상술한 종래 기술의 문제점들을 해결하기 위하여 발명된 것으로서, 본 발명의 목적은 자연석이 양 측면에 부착됨에 따라 자연 친화적일 뿐만 아니라 건물의 외벽은 물론 담장 등에도 적용하는 것이 가능하고, 조적시 더욱 향상된 강성을 가지며, 제조 공정이 단축되고 생산성을 향상시킬 수 있는 자연석을 이용한 블록 및 그 제조방법을 제공하는데 있다.Therefore, the present invention has been invented to solve the above-mentioned problems of the prior art, the object of the present invention is not only natural friendly as the natural stone is attached to both sides, it is possible to apply to the outer wall of the building as well as the fence, In addition, the present invention provides a block using natural stone and a method of manufacturing the same, which have more improved rigidity when being stacked, which can shorten the manufacturing process and improve productivity.

To manufacture.

즉, 상부에서 상부 금형(22)이 하강함과 동시에 측면 금형(23)(24)이 측면에서 전진함으로써 블록을 제조하게 되는 것이다.That is, the upper mold 22 is lowered at the top and the side molds 23 and 24 are advanced from the side to produce a block.

이때, 상기 하부 금형(21) 및 상부 금형(22)은 내측에 볼록부(21a)(22a)가 형성됨에 따라 블록(30)의 상, 하부면에는 자연석 안착부(31)(32)가 형성되고, 상기 측면 금형(23)(24)에는 내측에 돌출부(23a)(24a)가 형성됨에 따라 블록(30)에는 구멍(33) 및 요홈(34)이 각각 형성되어 진다.In this case, the lower mold 21 and the upper mold 22 are formed with natural stone seating portions 31 and 32 on the upper and lower surfaces of the block 30 as convex portions 21a and 22a are formed inside. As the protrusions 23a and 24a are formed in the side molds 23 and 24, holes 33 and recesses 34 are formed in the block 30, respectively.

그리고, 상기 상부 금형(22) 및 측면 금형(23)(24)이 블록(B)으로부터 분리된 후 콘베어 등의 수단에 의해 이동하면 도 3 에 도시한 바와 같이 블록(30)의 상부면에 형성된 자연석 안착부(32) 내에 자연석(40)을 안착시키고, 희석 모르타르를 도포하여 양생시킨다.When the upper mold 22 and the side molds 23 and 24 are separated from the block B and moved by a conveyor or the like, the upper mold 22 and the side molds 23 and 24 are formed on the upper surface of the block 30 as shown in FIG. 3. The natural stone 40 is seated in the natural stone seating portion 32 and cured by applying a diluted mortar.

상기 희석 모르타르는 시멘트 20중량%, 돌가루 10중량%, 규사 9중량%, 색소 1중량%, 나머지 물을 배합한 혼합물을 사용하여 적정의 색상이 나타나도록 한다.The diluted mortar is 20% by weight of cement, 10% by weight of stone, 9% by weight of silica sand, 1% by weight of the dye, using a mixture of the remaining water so that the appropriate color appears.

상기 색소는 황토색이 가장 바람직하며, 자연석(40)의 색상과 동일 또는 유사한 색상으로 형성하는 것이 바람직하다.The pigment is most preferably ocher color, it is preferable to form the same or similar to the color of the natural stone (40).

그리고, 상기 블록(30)의 상부면에 자연석(40)이 부착되면, 도 4 에 도시한 바와 같이 블록(30)을 180°로 뒤집어서 자연석 안착부(31) 내에 자연석(40)을 안착시키고 희석 모르타르를 도포한 후 양생시키면 도 5 에 도시한 바와 같이 양 측면에 복수 개의 자연석(40)이 부착되고, 내부에는 복수 개의 구멍(33)이 형성되며 양 측면에는 각각 요홈(32)이 형성된 자연석을 이용한 블록의 제조가 완료되는 것이다.Then, when the natural stone 40 is attached to the upper surface of the block 30, as shown in Figure 4, the block 30 is turned over by 180 ° to seat and dilute the natural stone 40 in the natural stone seating portion 31 When the mortar is coated and cured, as shown in FIG. 5, a plurality of natural stones 40 are attached to both sides, and a plurality of holes 33 are formed therein, and natural stones each having grooves 32 formed on both sides thereof. The manufacture of the used block is completed.

상술한 바와 같이 본 발명에 의하면, 블록의 내부에 복수 개의 구멍이 형성되고 양 측면에 요홈이 형성됨에 따라 조적시 좌우, 상하의 결합력이 증대될 뿐만 아니라 복수 개의 자연석이 부착됨으로써 자연 친화적이고, 품질이 더욱 향상되며, 건물 등의 외장재는 물론 담장 등에도 적용하는 것이 가능하고, 제조 공정이 용이하고 제조 코스트가 절감되는 등의 여러 가지 효과가 있다.As described above, according to the present invention, as a plurality of holes are formed in the inside of the block and grooves are formed on both sides, the binding force between the left and right and the upper and lower sides is increased as well as nature-friendly by attaching a plurality of natural stones. It is further improved, and can be applied to a wall or the like as well as an exterior material such as a building, and has various effects such as an easy manufacturing process and a reduction in manufacturing cost.

본 발명은 구체적인 실시예에 대해서만 상세히 설명하였지만 본 발명의 기술적 사상의 범위 내에서 변형이나 변경할 수 있음은 본 발명이 속하는 분야의 당업자에게는 명백한 것이며, 그러한 변형이나 변경은 본 발명의 특허청구범위에 속한다 할 것이다.Although the present invention has been described in detail only with respect to specific embodiments, it will be apparent to those skilled in the art that modifications and variations can be made within the scope of the technical idea of the present invention, and such modifications or changes belong to the claims of the present invention. something to do.
