Description
본 발명은 주로 보도 포장용으로 사용되는 자연석 투수 평판 블록 및 그 제조방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a natural stone pitch plate block mainly used for sidewalk pavement and a method of manufacturing the same.
종래에 대한민국 특허 제 0198022 호로 알려진 바 있는 세립자 고압 투수 블록 제조방법은 강도가 우수하고 투수성을 가지며 공극의 크기가 작아 표면이 거칠지 않은 블록을 얻기 위한 것으로서, 통상의 투수콘크리트 배합 비율에 의거 물, 골재, 시멘트, 감수제등을 혼합한 혼합물을 블록의 형틀에 투입하여 표면정리 후 진동 또는 진동 가압하는 공정, 이 공정 후 즉시 그 투수콘크리트층 상부에 세립도의 규사(모래), 시멘트, 물, 안료, 감수제등이 혼합된 혼합물을 투입하여 박층(5 ~ 20mm)을 이루도록하며 표면정리 후 진동 가압하는 공정, 이 공정에서 형성된 성형물을 형틀에서 끄집어내어 통상의 증기양생 또는 건조양생방법에 의거 양생시키는 공정, 이 공정에서 양생, 건조된 성형물을 현장에 설치한 후 그 표면에 수용성 아크릴수지, 에폭시, 우레탄 또는 불포화 수지등을 살포하여 그 공극에 침투시킨 후 통상의 방법에 의거 건조, 양생시키는 공정으로 이루어진 것이었다.Conventionally, the method of producing a fine-grained high permeability permeable block known as Korean Patent No. 0198022 is to obtain a block having an excellent strength, a permeability and a small pore size so that the surface is not roughened, , Sand, cement, water, water, etc., on the upper part of the permeable concrete layer immediately after the surface is cleaned and the vibration or vibration is applied after putting the mixture of aggregate, cement, (5 to 20 mm) by applying a mixture containing a pigment, a water reducing agent, and the like to form a thin layer (5 to 20 mm). After the surface preparation and vibration are applied, the formed product is taken out from the mold and cured according to a normal steam curing or dry curing Process, curing in this process, and drying the molded product are placed on the surface, and then water-soluble acrylic resin, epoxy, urethane or After the spraying of the unsaturated resin and the like penetrate into the voids was made of a step of dry basis, cured with a conventional method.
이와 같은 제조방법은 공장에서 양생, 건조된 블록을 현장으로 옮겨서 블록의 표면에 수지를 스프레이로 살포하는 것이어서 시공이 매우 번거로웠었고, 블록의 하부층을 먼저 형성하고 이 하부층 위에 블록의 표면을 이루는 상부층을 나중에 형성하는 것이었기 때문에 평탄도가 우수한 표면을 얻을 수 없었고, 블록상부층의 다짐정도가 부족하여서 특히 모서리 부위가 운반, 취급 및 시공도중에 파손되기 쉬운 등의 문제점이 있었다.In this manufacturing method, since the cured and dried blocks are moved to the site and sprayed with the resin on the surface of the block, the construction is very troublesome, and the lower layer of the block is formed first and the upper layer A surface with excellent flatness could not be obtained, and the degree of compaction of the upper layer of the block was insufficient. In particular, there was a problem that edge portions were easily damaged during transportation, handling, and construction.
그리고 대한민국 특허 공개번호 제 2003-0026642 호로 알려진 바 있는 골재를 이용한 투수블록의 제조방법 및 구조는 에폭시수지와 경화재를 혼합한 접착제를 골재와 혼합시킨 다음 형틀에 투입시켜 가압, 건조한 것으로서 공극률이 비교적 커서 투수성이 우수하나 앞에서 설명한 대한민국 특허 제 0198022 호에 의한 블록과 마찬가지로 블록의 하부층을 먼저 형성하고 그 위에 블록의 표면을 이루는 상부층을 나중에 형성하는 것이었기 때문에 평탄도가 우수한 표면을 얻을 수 없었고, 블록상부층의 다짐정도가 부족하게 되어서 특히 모서리 부위가 운반, 취급 및 시공도중에 파손되기 쉬운 등의 문제점이 있었고, 에폭시수지의 사용량이 많은 관계로 투수콘크리트로 형성된 블록에 비하여서 제조비용이 많이 들게되는 등의 문제점이 있었다.The method and structure of a permeable block using an aggregate as known in Korean Patent Publication No. 2003-0026642 is a method in which an adhesive mixed with an epoxy resin and a hardening material is mixed with an aggregate and then put into a mold and pressurized and dried. It is impossible to obtain a surface having a good flatness because the lower layer of the block is formed first and the upper layer constituting the surface of the block is formed later as in the case of the block according to Korean Patent No. 0198022 described above, The degree of compaction of the upper layer is insufficient and there is a problem that the corner portion is likely to be damaged during transportation, handling and construction, and the manufacturing cost is higher than that of the block formed of the permeable concrete due to the large amount of epoxy resin used .
본 발명은 우수한 투수성을 가짐과 아울러서 블록상부층의 강도가 매우 우수하고 표면을 연마처리함으로서 표면의 평탄도가 우수하며, 자연석 연마 표면층을 가지고 내마모성과 내동해성이 우수한 자연석 투수 평판 블록 및 그 제조방법을 제공하는데 기술적 과제를 둔 것이다.The present invention relates to a natural stone permeable flat plate block having excellent water permeability and excellent strength in the upper part of the block, excellent surface flatness by polishing the surface, excellent abrasion resistance and anti-durability with a natural stone polished surface layer, To provide a technical challenge.
본 발명은 도 1a ~ 도1f, 도 2 ∼ 도4에 예시한 바와 같이 크기가 5mm이상인 자연골재 80중량%, 물 4.5중량%, 투수시멘트 15.33중량% 그리고 섬유소 0.17중량%의 비율로 혼합한 혼합물을 블록의 상부층 형성물(a)로 하여서 형틀(b)에 그 높이가 1cm정도 되도록 먼저 투입하고 형틀(b)을 진동시켜 주는 단계와, 크기가 2.5 ~ 5mm정도인 자연석골재 80중량%, 물 4.5중량%, 투수시멘트 15.33중량% 그리고 섬유소 0.17중량%의 비율로 혼합한 혼합물을 블록의 하부층 형성물(c)로 하여서 상기 상부층 형성물(a)위에 투입하고 그 높이가 약 5cm정도 되도록 프레스(d)로 가압하는 단계와, 성형된 블록을 형틀(b)로부터 분리하여 양생하는 단계와, 양생된 블록의 표면을 연마처리하는 단계로 투수성 평판 블록을 제조하는 것이다.2 to 4, the present invention is a mixture of 80 wt% of natural aggregate having a size of 5 mm or more, 4.5 wt% of water, 15.33 wt% of water permeable cement and 0.17 wt% of cellulose, (B) by vibrating the mold (b) so that the height of the mold (b) is about 1 cm and the mold (b) (A) of 4.5% by weight, water-permeable cement 15.33% by weight and cellulose 0.17% by weight as a lower layer formation (c) of a block, d), curing the formed block separated from the mold (b), and polishing the surface of the cured block to produce a water permeable flat plate block.
본 발명에 있어서, 보도를 시공할 때 블록과 블록사이에 모래채움하기 위하여 블록과 블록사이에 간격을 유지시켜주는 작업을 보다 정확하고 용이하게 실시할수 있도록 해주기 위해서는 도 3에서 이점쇄석으로 표현한 바와 같이 블록의 측면 중 적어도 2개이상의 측면에 블록의 높이보다 낮은 약 5cm정도의 높이와 약 3mm정도의 두께를 가진 합성수지띠(e)를 고주파로 접합시켜 주는 것이 좋다.In the present invention, in order to more precisely and easily carry out the work of maintaining the interval between the block and the block in order to fill the sand between the block and the block when constructing the sidewalk, It is preferable that a synthetic resin band (e) having a height of about 5 cm lower than the height of the block and a thickness of about 3 mm is bonded to at least two side faces of the block at a high frequency.
이와 같이 제조된 본 발명에 의한 투수성 평판 블록은 블록의 상부층(a)이 진동에 의해서 다져진 다음 블록의 하부층 형성물(c)이 성형될 때 프레스(d)로 가압된 것이기 때문에 블록의 하부층을 먼저 성형하고 상부층을 나중에 성형해왔었던 종래의 블록에 비하여서 상부층의 강도가 매우 우수하게 된다.Since the waterproof plate block according to the present invention thus manufactured is pressed by the press (d) when the upper layer (a) of the block is compacted by vibration and then the lower layer formation (c) of the block is molded, The strength of the upper layer becomes much higher than that of the conventional block which was formed first and the upper layer was formed later.
특히 상부층의 모서리 부위가 치밀하게 되므로 종래에 비하여서 매우 견고하게 되기 때문에 블록을 운반, 취급 및 시공할 때 모서리 부위가 쉽게 파손되는 것이 효과적으로 방지된다.In particular, since the corner portion of the upper layer is dense, it is very strong compared with the conventional one, so that it is effectively prevented that the corner portion is easily broken when carrying, handling, and constructing the block.
그리고 블록 상부층에 있는 자연골재(10)의 표면이 평탄하게 연마처리된 것이기 때문에 즉, 자연골재 특유의 질감, 색상 및 광택이 발현되어 자연친화적인 표면을 가질 뿐만 아니라 보행할 때 촉감을 좋게 해준다.Since the surface of the natural aggregate (10) on the upper block of the block is polished smoothly, that is, the unique texture, color and gloss of the natural aggregate are expressed, thereby not only having a natural-friendly surface but also improving the feeling of walking.
또 본 발명에 의한 자연석 투수 평판 블록은 도 4에 예시한 바와 같이 투수성이 매우 우수하고 섬유소가 포함된 것이기 때문에 동절기에서 해빙기로 접어들 때 수축, 이완되더라도 균열이 방지되므로 내구성과 내동해성이 우수하게 된다.As shown in FIG. 4, the natural stone permeable flat plate block according to the present invention has excellent water permeability and contains fibrillated material. Therefore, even if it shrinks and relaxes when it is folded from a winter season to a frost season, cracks are prevented, .
본 발명은 상부층의 강도와 투수성이 우수하고, 특히 모서리의 형태 안정성과 강도가 우수하며, 자연친화적인 표면을 갖고, 보행 촉감이 우수한 등의 장점이 있다.The present invention is advantageous in that the upper layer is excellent in strength and water permeability, particularly excellent in shape stability and strength of corners, has a natural-friendly surface, and has excellent walking feeling.
