본 발명은 진지구축용 조립식 벽돌과 그의 제조방법에 관한 것으로서, 더욱 상세하게는 군사용진지의 구축이나 방벽의 구축에 적합하도록 높은 강도를 가지며, 축조시 결합이 용이하게 되도록 성형된 진지구축용 조립식 벽돌과 그의 제조방법에 관한 것이다.The present invention relates to a prefabricated brick for building a serious earthquake and a method of manufacturing the same, and more particularly, has a high strength to be suitable for the construction of a military camp or a construction of a barrier, a prefabricated brick for building a true earthquake is molded to facilitate the coupling during construction. And to a method for producing the same.

종래에 군사용으로 방벽이 구축이나 방카구축등 방어진지를 축조할때 통상적인 벽돌에 시멘트제품을 혼합사용하여 축조하거나 또는 흙과 석회등이 섞인 벽돌을 현장에서 직접 축조하여 방벽을 쌓는등 진지구추을 하여왔고, 또 일부는 조립식 벽돌들이 사용되기도 하였다.In the past, when building barriers or building defensive positions such as banca construction for military use, it has been built using ordinary cement mixed with cement products or building bricks mixed with soil and lime on site to build barriers. In some cases, prefabricated bricks were used.

그러나 종래에 사용되었던 벽돌들은 모두가 군사용 진지구축에 적합한 벽돌이라고 할 수 없는 것들로서, 예컨데 방수, 방한, 방동등에 문제가 많았고, 특히 구축된 벽돌들이 포화등에 의하여 쉽게 파괴되었을때 재건하기도 매우곤란하였으며 구축시 어려움도 많았다. 특히 국내외로 군사상 매우 비중이 큰 국내전선에서의 진지에 사용되는 벽돌은 더욱 견고해야할 필요성이 요구되고 있으며, 그뿐 아니라 국지전에 대비하여 향토방위등의 중요성이 부각되는 시정에서 후방지역의 진지도 반영구적으로 사용되어져야 하는바, 종래의 방법으로는 진지에 사용된 벽돌을 자주 보수하여야 하는등 견고하지 못하였으며 일부파손에 의해서도 재건하는데 많은 비용이 소모되였으므로 국가적인 손실이 매우 컸었다.However, the bricks used in the past are not all bricks suitable for military camp construction. For example, there were many problems in waterproofing, cold protection, and wintering, and it was very difficult to rebuild the bricks especially when the built bricks were easily destroyed by saturation. There was also a lot of difficulties in building. In particular, the bricks used for serious positions in domestic fronts, which have a high military weight both at home and abroad, are required to be more robust.In addition, since the importance of local defense is emphasized in preparation for local warfare, the rear area is also semi-permanent. In the conventional method, the bricks used in the camp were not firmly repaired, and they were expensive to rebuild by some damages.

본 발명은 이와같은 종래의 국방상 진지구축에 따른 난점을 해소하고 높은 강도를 가진 재질로 더욱 편리하고 견고하게 진지를 구축하도록 하기 위함은 물론, 방수, 방한, 방동의 효과가 크고, 매우 견고한 진지구축용 조립식벽돌과 이를 제조하는 방법을 제공하는데 그 목적이 있다.The present invention is to solve the difficulties caused by the conventional defense camps and to build a more convenient and robust position with a material having a high strength, as well as the effect of waterproof, cold weather, anti-vibration, very strong The purpose of the present invention is to provide a prefabricated brick and a method of manufacturing the same.

본 발명을 상세히 설명하면 다음과 같다.The present invention is described in detail as follows.

본 발명은 일반적인 점토에 시멘트와 혼화제를 혼합하고 압축 성형시켜서 벽돌을 제조하는데 있어서, 주성분인 점토와 시멘트에 부성분인 혼화제를 4:1:3의 용적비로 혼합시키되 혼화제로서는 아크릴산, 불포화폴리에스테르수지, 석회석, 염화칼슘 및 염화마그네슘의 혼합물질(제 1 조성물)과 납비누와 벤젠의 혼합물질(제 2 조성물)을 2:1의 용적비로 혼합시킨 혼합물을 사용하여 압축 성형시켜서, 결합구멍과 결합요철이 형성된 벽돌본체를 성형시키되 벽돌본체의 양면으로 서로 엇갈린턱이 형성되도록 하고, 결합요철이 형성된 벽돌본체의 상부에는 결합홈을 형성시키며, 그 직하방에는 상기 결합홈에 삽입 체결될 수 있고 결합구멍이 부설된 결합돌기를 형성시켜서 결합구멍에 결합나사를 체결시켜 벽돌본체가 연속적으로 조립될 수 있도록 된 진지구축용 조립식 벽돌과 그의 제조방법인 것이다.In the present invention, in the manufacture of bricks by mixing and compression-molding cement and admixture with general clay, the main admixture with admixture admixtures with clay as a subcomponent in a volume ratio of 4: 1: 3 is used as acrylic admixture, unsaturated polyester resin, The mixture of limestone, calcium chloride and magnesium chloride (first composition) and the mixture of lead soap and benzene (second composition) were compression-molded using a mixture of 2: 1 in volume ratio, so that the bonding holes and the unevenness were Molding the formed brick body to form a staggered jaw formed on both sides of the brick body, the coupling groove is formed on the upper portion of the brick body is formed, the coupling groove can be inserted into the coupling groove directly below the coupling hole and the coupling hole is The place where the brick body can be continuously assembled by fastening the coupling screw to the coupling hole by forming the attached coupling protrusion. Axis prefabricated brick and is his method.

본 발명을 더욱 상세히 설명하면 다음과 같다.The present invention is described in more detail as follows.

본 발명의 주성분인 점토는 그 입자크기가 약 30 내지 50메쉬정도로 분쇄된 것이며, 시멘트는 통상적으로 사용되는 포오틀란드 시멘트로서, 이들의 혼합방법은 일반적인 방법으로 실시한다.Clay, which is the main component of the present invention, is ground to a particle size of about 30 to 50 mesh, and cement is a commonly used portland cement, and the mixing method thereof is performed by a general method.

한편, 상기의 주성분에 첨가되는 부성분으로서는 혼화제가 사용되는데, 이 혼화제는 아크릴산, 불포화 폴리에스테르수지, 석회, 염화칼슘과 염화마그네슘의 혼합물(제1 조성물)에 납비누와 벤젠의 혼합물(제 2 조성물)을 혼합시켜서 제조된 것이다.On the other hand, a admixture is used as a subcomponent added to the main component, which is a mixture of lead soap and benzene in a mixture (first composition) of acrylic acid, unsaturated polyester resin, lime, calcium chloride and magnesium chloride (second composition). It is prepared by mixing.

예컨대, 제 1 조성물은 아크릴산 40내지 45부에 물 5내지 10부를 혼합시킨 다음 여기에 불포화 폴리에스테르수지 20내지 25부와 삭회석 10내지 17부 및 염화칼슘 10내지 15부, 염화마그네슘 4내지 10부를 충분한 시간을 두고 첨가 혼합시킨다. 이때의 반응도는 60℃ 내지 80℃로 유지시켜서 실시하는 것이 좋다.For example, the first composition may be mixed with 40 to 45 parts of acrylic acid, 5 to 10 parts of water, and then 20 to 25 parts of unsaturated polyester resin, 10 to 17 parts of axalite, 10 to 15 parts of calcium chloride, and 4 to 10 parts of magnesium chloride. Allow sufficient time to add and mix. It is preferable to carry out by maintaining reaction degree at this time at 60 to 80 degreeC.

이중에서 아크릴산은 특히 높은 점성도를 가진 용액으로서 불포화 폴리에스테르수지와 쉽게 중합반응을 일으켜서 강력한 점착성을 갖게하므로서 주성분인 점토 및 시멘트등의 입자와 혼화될때 매우 강한 응렬작용을 나타내게 된다. 그리고 제 1 조성물 제조시 약간의 중합반용을 돕기 위한 것이다.Among them, acrylic acid is a solution having a particularly high viscosity, and easily polymerizes with an unsaturated polyester resin to have strong adhesiveness, and thus shows very strong coagulation when mixed with particles such as clay and cement which are main components. And it is to help the use of some polymerization in preparing the first composition.

한편, 여기에 첨가되는 석회석은 아크릴산과 불포화 폴리에스테르수지와 반응하여 응결작용을 더욱 확고하게하고 경도를 높게 유지하도록 하기 위한 것이며, 염화마그네슘을 첨가시키는 것은 응결작용을 신속하게 하고, 벽돌의 제조시 좋은 탈형효과를 갖도록하는데 있다.On the other hand, the limestone added here is to react with acrylic acid and unsaturated polyester resin to make the condensation reaction more firm and maintain the hardness, and the addition of magnesium chloride accelerates the condensation reaction and in the manufacture of bricks. To have a good demolding effect.

본 발명에 따른 상기 제 1 조성물에 혼합되어지는 제 2 조성물의 제조는 납비누 20내지 25부에 벤젠 75내지 80부를 혼합시킨 다음 필요에 따라서 상기 혼합용액에 소량의 착색제를 첨가하여서 제조한다.The second composition to be mixed with the first composition according to the present invention is prepared by mixing 75 to 80 parts of benzene with 20 to 25 parts of lead soap, and then adding a small amount of colorant to the mixed solution as needed.

여기서 사용되는 납비누는 그 일반식이[(RCOO)2Pb]로서 수지등의 안정제나 유지중합체 또는 방수제로 사용될뿐 아니라 모조피혁의 제조등에도 유용하게 사용될 수 있는 것으로서 벤젠등에 잘 녹는 금속비누중의 하나인 것이다.The lead soap used here is a general formula [(RCOO) 2 Pb], which can be used not only as a stabilizer such as resins, as an oil-based polymer or as a waterproofing agent, but also useful in the manufacture of imitation leather. It is one.

상기와 같은 툭성을 갖는 납비누는 건조제로서 성형된 제품의 신속한 응결작용과 높은 강도에 도움을 줄뿐 아니라 상술한바와 같이 방수효과가 뛰어나고 방한등의 효과도 매우 우수하므로 본 발명에 사용되기에 적합한 것이다.Lead soap having a fluffyness as described above is suitable for use in the present invention because it not only helps the quick coagulation and high strength of the molded product as a desiccant but also has excellent waterproof effect and excellent cold protection as described above. .

한편, 상기 제2조성물에 첨가되는 착색제는 본 발명의 혼화제와 첨가된 벽돌의 색을 일반의 색과는 달리 국방상 유리한 색, 또는 숲속이나 들판 등에서 눈에 잘띄지 않도록하기 위한 색을 첨가하는 것으로서 꼭 첨가하는 것은 아니며 만일, 착색제를 첨가할시는 납비누와 벤젠의 혼합이 완전히 이루어진 후 착색제를 혼합시키도록 하는것이 좋다.On the other hand, the colorant added to the second composition as the addition of the color of the admixture of the present invention and the added brick, unlike the general color in favor of the defense, or a color not to stand out in the forest or field, etc. If the colorant is added, it is better to mix the colorant after the mixing of lead soap and benzene is completed.

이와같은 방법으로 제조된 제 2 조성물을 상기 제 1 조성물에 혼합시킬 때에는 상기 제 2 조성물을 제조한 즉시 제 1 조성물에 혼합시키는 것이 좋으며, 이때의 혼합비는 제 1 조성물과 제 2 조성물을 2 : 1의 용적비로 혼합시키며, 이 혼합은 고반상태에서 약 20내지 40분동안 혼합시키는 것이 적당하다.When the second composition prepared in this manner is mixed with the first composition, it is preferable to mix the second composition with the first composition immediately after the preparation, and the mixing ratio of the first composition and the second composition is 2: 1. Mix in a volume ratio of, which is suitably mixed for about 20 to 40 minutes at high peak.

이렇게 제조된 혼화제는 매우 강력한 강도를 가지며 방수, 방한, 방동의 효과를 갖도록하는 매우 특수하고, 양질의 혼화제인 것이다.The admixture thus prepared is a very special, high quality admixture that has very strong strength and has the effect of waterproofing, wintering, and anti-freezing.

본 발명에 따르면 점토, 시멘트 및 혼화제를 혼합함에 있어서 용적비로 4 : 1 : 3으로 혼합시키는데 먼저, 점토와 시멘트를 균질로 혼합시키고 강력하게 회전하는 혼합기내에서 혼화제를 첨가 혼합시켜서 혼화제를 점토 및 시멘트재질에 균일하게 혼합되도록 한다음 이 혼합재질을 즉시 압축성 형기로 보내어 제조전에 일부라도 미리 경화되는 것을 방지하면서 본 발명에 따른 벽돌을 성형시킨다.According to the present invention, when mixing clay, cement and admixture in a volume ratio of 4: 1: 3, the admixture is mixed with clay and cement by homogeneously mixing clay and cement and adding admixture in a strongly rotating mixer. The mixture is allowed to be uniformly mixed with the material, and then the mixed material is immediately sent to a compression molding machine to form a brick according to the present invention while preventing any part of it from being pre-cured before manufacturing.

이때 압축성형은 약 180-240kg/cm2의 압력에서 실시하는 것이 가장 적당하다.At this time, compression molding is most appropriately performed at a pressure of about 180-240kg / cm 2 .

한편, 본 발명에 따른 벽돌은 여러형태로 성형이 가능하지만 진지구축용으로서 적합한 벽돌모양은 제1도에 예시된 바와 같은 모양이면 가장 좋다.On the other hand, the brick according to the present invention can be molded in various forms, but the brick shape suitable for the construction of the earthquake is best if the shape as illustrated in FIG.

즉 제1도에 예시된 벽돌의 구조를 상세히 살펴보면, 결합구멍과 결합요철이 형성된 벽돌의 본체(1a)와 본체(1b)가 빗겨서 결합된 듯한 형체로 되도록 성형시켜 결국 양면으로 서로 엇갈린 턱(2)이 형성되게 하고 결합요철이 형성된 벽돌본체(1b)의 상부에는 결합홈(3a)(3b)을 만들고, 그 직하방에는 상기 결합홈(3a,3b)과 꼭맞게 체결될 수 있는 결합벽기(4a,4b)를 형성시킨다. 이와같이 결합요철과 턱(2)을 형성시키면서 도면에서와 같이 다른 벽돌의 결합홈(3a,3b)과 결합돌부(4a,4b)가 끼워지고 턱(2)이 결속될 수 있도록 각각 결합구멍(5a,5b)을 뚫어 두개이상의 벽돌이 조립되었을때 체결나사(6)로 채결시킬 수 있도록 한 구조로 되어 있다.That is, when the structure of the brick illustrated in FIG. 1 is described in detail, the main body 1a and the main body 1b of the brick in which the coupling holes and the concave-convex protrusions are formed are combed to form a combined shape, and thus the jaws are alternately crossed on both sides ( 2) is formed and the coupling groove (3a) (3b) is formed in the upper portion of the brick body (1b) formed with coupling irregularities, the coupling wall that can be fastened to the coupling groove (3a, 3b) directly below (4a, 4b) are formed. In this way, while forming the coupling unevenness and the jaw (2), as shown in the drawing, the coupling grooves (3a, 3b) and the engaging projections (4a, 4b) of the other bricks are fitted, respectively, the coupling holes (5a) to bind the jaw (2) , 5b) is made so that when the two or more bricks are assembled, the fastening screw (6) can be crushed.

이와같은 구조를 갖는 벽돌은 그 크기를 통상적인 것보다 크게하여 용이하게 조립될 수 있도록 하며 크기를 작게하는 경우에는 통상적인 벽돌크기만 하게 할 수 있고, 벽돌크기만하게 제조하는 경우 결합구멍을 형성시키기가 곤란하므로 결합구멍은 형성시키지 않고 결합요철에 의해서만 서로 결합되도록 한다.The brick having such a structure can be easily assembled by making the size larger than usual, and in the case of reducing the size of the brick, it is possible to make only the normal brick size. Since it is difficult, the coupling holes are not formed so that they are coupled to each other only by coupling recesses and protrusions.

본 발명에 따라 제조된 제1도와 같은 벽돌은 결합시 턱(2)에 의하여 서로 견고하게 결합되고 결합구멍(5a,5b)을 결합나사(6)로 체결시키므로서 더욱 단단한 결합효과를 갖게한다.The brick as shown in FIG. 1 manufactured according to the present invention is firmly coupled to each other by the jaw 2 at the time of joining, and has a more firm coupling effect by fastening the coupling holes 5a and 5b to the coupling screw 6.

결합요철, 즉 결합홈(3a,3b) 및 결합돌부(4a,4b)의 크기는 적당한 크기로 하면되며, 이는 벽돌의 크기에 따라 정하면 된다.Coupling unevenness, that is, the size of the coupling grooves (3a, 3b) and the coupling protrusions (4a, 4b) should be appropriate size, which may be determined according to the size of the brick.

본 발명에 따라 성형된 벽돌을 조립시켜 방벽을 쌓을때 본 발명에 따른 혼화제가 혼합된 점토와 시멘트의 혼합제질을 조립되는 벽돌사이에 발라 조립시키면 더욱 좋다.When assembling the bricks molded according to the present invention to build a barrier, it is better to apply the mixed material of clay and cement mixed with the admixture according to the present invention between the bricks to be assembled.

제2도에서는 본 발명에 따라 성형된 벽돌의 결합된 상태를 나타내고 있는데 그 결합이 매우 용이하고 견고하게 결합되며, 결합된 벽돌을 해체하기에도 간편하며 진지를 구축한뒤 포화에 일부가 파손되어도 용이하게 갈아끼여 복구할 수 있고, 포화를 맞은 후에도 전체적으로 지지의 형체가 그대로 유지될 수 있는 효과가 있다.Figure 2 shows the combined state of the bricks formed according to the present invention, the combination is very easy and firmly coupled, easy to dismantle the combined bricks and easy to break part of the saturation after establishing the position It can be repaired and repaired, and the shape of the support can be maintained as it is after the saturation.

한편 벽돌성형시 벽돌을 너무크게 제조하게 되면 운반이나 축조등에 어려움이 있으므로 너무 크지않는 정도 즉 가로120cm 세로 60cm정도의 크기이면 적당한 상기 크기에 국한하는 것은 아니다.On the other hand, if the brick is manufactured to be too large, there is a difficulty in carrying or construction, so if the size is not too large, 120cm length 60cm size is not limited to the appropriate size.
