본 발명은 토목·건축용 보강재인 지오그리드(Geogrid) 및 그의 신규한 제조방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a geogrid, which is a reinforcing material for civil engineering, and a novel manufacturing method thereof.
지오그리드는 지반강화, 지반처리, 콘트리트처리전 토양 보강, 공사용 차폐등의 토목·건축용 보강재로 사용되는 것으로, 종래의 플라스틱제(연신물) 지오그리드는 범용성 플라스틱(폴리에스테르, 폴리프로필렌등)을 연신시켜 제조하였다. 그러나, 이와 같은 종래의 지오그리드는 강력이 낮고 신율이 크기 때문에 높은 하중 또는 부하가 적용되는 용도에는 사용하기 곤란하며, 이러한 약점을 개선하기 위해 두께를 증가시키면 지오그리드의 무게가 증가하고 이로 인해 운반성 및 작업성이 저하될 우려가 있었다. 이러한 단점을 개선하기 위해서 대안으로 섬유를 주체로 사용하고 이에 수지를 함침,피복한 지오그리드가 검토되어 레노직(弱織)형태에 의한 격자상 직물을 사용한 것이 개발되기도 하였으나, 생산속도가 낮고 실의 강력이용율이 낮은 단점을 갖고 있어 이에 대한 개선이 요구되어 왔다.Geogrid is used as a reinforcing material for civil engineering and construction, such as reinforcing soil, soil treatment, soil reinforcement before concrete treatment, shielding for construction, etc., and conventional plastic (stretched) geogrid is made of general purpose plastics (polyester, polypropylene, etc.) Prepared. However, these conventional geogrids are difficult to use in applications with high loads or loads due to their low strength and high elongation, and increasing the thickness of the geogrid to improve these weaknesses increases the weight of the geogrid and thereby There was a fear that the workability was reduced. In order to remedy these shortcomings, the use of fiber as a main agent and the impregnated and coated geogrids have been examined, and the use of lattice fabrics in the form of leno-jig has been developed. It has a disadvantage of low utilization rate has been required to improve.
본 발명의 목적은 이와 같은 종래기술의 문제점을 극복하는 것으로 기존의 제품에 비해 중량이 작아 시공시 작업성이 우수하고, 내부식성이며 강력효율이 우수한 토목·건축용 보강재인 지오그리드 및 그의 제조방법을 제공하는 것이다.An object of the present invention is to overcome the problems of the prior art and to provide a geogrid and a method of manufacturing the reinforcing materials for civil engineering and construction excellent in workability, excellent corrosion resistance and strong efficiency when construction is smaller than conventional products It is.
즉, 본 발명은 인장강도 8g/d이상, 신도 10-17%, 섬도 1000~1500데니어인 고강력 합성섬유 필라멘트사를 2가닥 이상 합연하여 3000~10000 데니어의 합연사로 만든후, 이 합연사를 단사 또는 수가닥을 경위사로 사용하되 경사의 경우 300~500데니어의 합성섬유 필라멘트 지경사로 얽어맨 것을 사용하여 격자크기 4~50mm인 레노직의 격자상 시이트를 제편하고, 이 격자상 시이트위에 합성수지를 코팅하는 것을 특징으로 한 토목·건축용 보강재 지오그리드의 제조방법을 제공하는 것이다.In other words, the present invention is a combination of two or more high-strength synthetic fiber filament yarn having a tensile strength of 8g / d or more, elongation 10-17%, fineness 1000 ~ 1500 denier made of a twisted yarn of 3000 ~ 10,000 denier Using single yarn or suede as the weft yarn, in the case of warp yarns, intertwine a lattice sheet of 4 to 50 mm of lattice size using synthetic fiber filament local warp yarns of 300 ~ 500 denier, and put synthetic resin on the lattice sheet. To provide a method for manufacturing geogrid reinforcement for civil engineering, characterized in that the coating.
이하에서 본 발명을 첨부 도면을 참고하여 더욱 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.
본 발명에서 사용하는 합성섬유 필라멘트사는 타이어코드등 산업용으로 사용되는 고강력사로서 바람직하게는 폴리에스터, 폴리아미드, 폴리비닐알콜 섬유가 좋으며 1000 내지 1500 데니어의 폴리에스터 고강력사를 사용하여 합연공정을 통해 3000~10000데니어의 합연사를 제조하여 사용하는 것이 특히 바람직하다. 특히 강력(tenacity)의 측면에서 인장강도는 8g/d 이상인 원사를 사용하여야 하는데, 원사의 인장강도가 8g/d 미만이면 충분한 보강효과를 내기 위해서 그 만큼의 원사가 더 필요하게 되고 그로 인해 작업성에 있어 문제가 발생될 소지가 있고 경제적인 측면에서도 비효율적이다.Synthetic fiber filament yarn used in the present invention is a high-strength yarn used for industrial use, such as tire cords, preferably polyester, polyamide, polyvinyl alcohol fiber, and through the jointing process using a polyester high-strength yarn of 1000 to 1500 denier It is especially preferable to manufacture and use 3000 to 10,000 denier twisted yarns. In particular, in terms of tenacity, a tensile strength of more than 8 g / d should be used. If the tensile strength of the yarn is less than 8 g / d, more yarns are needed to provide sufficient reinforcing effect. There is a possibility of problems and economic inefficiency.
본 발명에서 사용되는 원사의 신도는 10~17%의 범위내인 것이 필요하며, 신도가 10% 미만이면 최종제품에 있어 사용시 부분순간 내충격성이 저하되고, 이와 반대로 신율이 17%를 초과하는 경우에는 사용시의 형태안정성이 문제될 소지가 있으므로, 본 발명에서 원사의 신도는 상기 범위내인 것이 필수적이다.The elongation of the yarn used in the present invention needs to be in the range of 10 to 17%, and when the elongation is less than 10%, the impact resistance at the time of use in the final product is lowered, whereas the elongation exceeds 17%. Since there is a possibility that form stability during use may be a problem, the elongation of the yarn in the present invention is essential to be within the above range.
본 발명에서 격자상 시이트를 제조하는데 사용되는 경위사는 상술한 원사 섬도가 1000~1500데니어인 고강력사를 경위사 총 데니어가 3000~10000데니어가 되도록 2가닥이상 연사 및 합연하여 만든 합연사를 단사 또는 수가닥을 합한 것을 사용하는데 총 데니어 및 연사수는 최종목적물의 용도에 따라 임의 선택가능하다.Inspector yarn used to manufacture the lattice sheet in the present invention single yarn or twisted yarn made by twisting and joining two or more strands so that the total warp yarn denier is 3000-10000 denier, the high-strength yarn with the above-mentioned yarn fineness of 1000 ~ 1500 denier The sum of the number of strands is used, and the total denier and number of yarns can be arbitrarily selected according to the purpose of the end use.
본 발명에서 제편시 상술한 합연사를 수가닥 경사에 사용함에 있어 형태안정성을 부여하기 위해 경사를 휘감는데 이용되는 지경사(ground warp)는 300~500데니어의 합성섬유 필라멘트사를 사용하는 것이 좋고 이의 적용방법은 제1도에 도시한 레노직을 제편하는데 있어 다수본을 사용해야하는 경사에 제2도와 같이 경사내 다수 본간의 형태 안정을 기할 수 있도록 얽어매는 방식으로 적용한다.In the present invention, the warp yarn used to wind the warp yarn to impart morphological stability in the use of the above-mentioned twisted twist yarn in the warp yarn warp is preferably 300 to 500 denier synthetic fiber filament yarn. The method of application is applied in such a way that the shape stability of the multiple bones in the slope can be secured as shown in FIG.
즉, 제1도는 레노직의 일반적 모식도로서 위사(2)를 경사(1)가 엮어매는 조직이며, 본 발명에서는 제2도와 같이 다수본의 경사구성 합연사(3, 3', 3, 3')을 한방향으로 확실하게 정렬시켜 강도활용성을 높이려는 것으로 다수본의 경사구성 합연사(3, 3', 3, 3')를 지경사(4)가 얽어매 감싸고 있다.That is, FIG. 1 is a general schematic diagram of Lenozig, a structure in which the warp yarn 1 is intertwined with the weft yarn 2, and in the present invention, as shown in FIG. 2, the warp yarn composite yarns 3, 3 ', 3, 3' as shown in FIG. ), The sloping twisted yarns 3, 3 ', 3, and 3' are enclosed and enclosed by the local warp yarn 4 in order to reliably align one direction in order to increase the strength utilization.
본 발명에서 격자상 시이트 위에 도포되는 코팅수지는 일반 연약 지반 보강 및 토목·건축용의 경우에는 내후성, 내산성이 우수하고 가격이 저렴한 염화비닐수지를 코팅수지로 사용하는 것이 좋고, 콘크리트 보강용에는 콘크리트와 접착력이 우수한 아크릴수지를 사용하는 것이 좋다. 특히, 아크릴수지의 경우에는 분자구조내에 관능기로서 산(-COOH)과 수산기(-OH)가 존재하여 콘크리트와의 접착력이 우수한 장점이 있어 콘크리트용으로 적합하다.In the present invention, the coating resin applied on the lattice sheet is preferably used as a coating resin in the case of general soft ground reinforcement, civil engineering and construction, and has excellent weather resistance, acid resistance and low cost, and concrete reinforcement for concrete reinforcement. It is better to use acrylic resin that has excellent adhesion. In particular, in the case of acrylic resin, acid (-COOH) and hydroxyl group (-OH) are present as functional groups in the molecular structure, and thus, the adhesive strength with the concrete is excellent, so it is suitable for concrete.
본 발명의 지오그리드는 토목 및 건축용 보강재이므로 내후성, 내산성 및 내균성(내충성)등이 요구되는데, 본 발명에서는 기존의 섬유상 지오그리드에서 발생할 수 있는 세균이나 곰팡이 등에 의한 부식을 방지할 수 있도록 항균제를 코팅수지에 첨가해줌으로써 내균성이 우수한 섬유상 지오그리드를 제조할 수 있다.Since the geogrid of the present invention is a reinforcing material for civil engineering and construction, it is required to have weather resistance, acid resistance and bacteria resistance (insect resistance), etc. In the present invention, an antimicrobial agent is coated with an antimicrobial agent to prevent corrosion due to bacteria or fungi that may occur in existing fibrous geogrids It is possible to prepare a fibrous geogrid excellent in bacteria resistance by adding to the.
본 발명에서 사용가능한 항균제는 공사 차폐용의 경우는 유기유황 화합물 계통의 항균제를 가소제에 대해 0.25~0.5중량% 정도 첨가 사용하는 것이 바람직하며, 그외의 용도로는 유기 비소 화합물계통의 항균제를 수지중량에 대해 0.05%이하의 양으로 사용하는 것이 바람직하다. 유기유황계 화합물은 설피드, 멀캅탄등의 유황을 함유하는 유기화합물이고, 유기 비소 화합물은 메탄아르손산철, 메탄아르손산철암모늄, 메탄아르손산칼슘등의 비소를 함유하는 유기화합물이다.In the case of construction shielding, the antimicrobial agent that can be used in the present invention preferably uses an organic sulfur compound-based antimicrobial agent in an amount of 0.25 to 0.5% by weight based on the plasticizer. It is preferable to use in an amount of 0.05% or less relative to. The organic sulfur compound is an organic compound containing sulfur such as sulfide and mercaptan, and the organic arsenic compound is an organic compound containing arsenic such as iron methane arsenate, ammonium ferric methane arsenate, and calcium methane arsenate.
본 발명의 토목·건축용 보강재인 지오그리드의 격자상시이트에서 격자 크기는 통상 4~50mm 범위에서 목적에 따라 결정되며, 용도에 따라서 이 범위를 벗어나는 것도 가능하다. 격자의 크기는 제2도의 d,d'를 측정한 값이다. 특히 높은 하중에 대해 변형이 적어야 하므로 인장강도가 1t/m이상, 바람직하게는 2t/m이상이어야 하고, JIS L1096A법에 의해 측정되는 강연도는 150mm 이상의 경도를 갖는 것이 요구된다.In the grid-like sheet of geogrid, which is a reinforcing material for civil engineering and construction of the present invention, the lattice size is usually determined in accordance with the purpose in the range of 4 to 50 mm, and may be out of this range depending on the use. The size of the grating is a measure of d, d 'in FIG. In particular, since the deformation should be small for high loads, the tensile strength should be 1 t / m or more, preferably 2 t / m or more, and the stiffness measured by the JIS L1096A method is required to have a hardness of 150 mm or more.
본 발명에 의해 제조되는 토목·건축용 보강재인 지오그리드는 인장강도가 우수하고 신도가 낮은 고강력사를 사용하므로 기존의 제품에 비해 낮은 중량의 제품을 제조할 수 있으며, 이로 인해 시공시 작업성이 향상되는 이점을 갖는다. 또한 코팅수지내에 항균제를 첨가하므로서 토양내의 세균 및 곰팡이 등에 의한 소재의 부식을 방지할 수 있고, 더 나아가 제편에 의해 형성된 편물의 구조가 직선상으로 구성되어 있어 구성사 대부분이 장력 멤버(tension member)로서 작용되며, 이로 인해 섬유의 강력효율이 우수한 이점도 갖는다.Geogrid, which is a reinforcing material for civil engineering and construction manufactured by the present invention, uses high-strength yarns with excellent tensile strength and low elongation, thereby making it possible to manufacture products having a lower weight than existing products, thereby improving workability during construction. Has an advantage. In addition, by adding an antimicrobial agent to the coating resin, it is possible to prevent corrosion of the material caused by bacteria and mold in the soil, and furthermore, the structure of the knitted fabric formed by the piece is composed of a straight line, and most of the constituent yarns are tension members. It also acts as a result, which also has the advantage of excellent strength efficiency of the fiber.
