Description
본 고안은 콘크리트 구조물이나 벽돌 등의 성형시 이들 구조물에 첨가되어 강도와 인성 등의 기계 및 물리적인 성질을 향상시켜 주기 위한 콘크리트 보강재에 관한 것이다.The present invention relates to concrete reinforcement for improving the mechanical and physical properties such as strength and toughness added to these structures during the molding of concrete structures or bricks.
더욱 상세하게는, 콘크리트 보강재를 고장력 합성수지재로 성형하여 그 길이방향에 일정간격의 압착홈 및 돌출부를 형성하므로써 구조물과의 부착성 및 분산성을 향상시켜 콘크리트 구조물의 균열방지와 취성을 보완하기에 적합하도록 한 콘크리트 보강재에 관한 것이다.More specifically, the concrete reinforcement is molded from high-strength synthetic resin to form a pressing groove and a protrusion having a predetermined interval in the longitudinal direction to improve adhesion and dispersibility with the structure to compensate for crack prevention and brittleness of the concrete structure. A concrete reinforcement is made.
일반적으로 콘크리트 구조물이나 벽돌 등을 성형할 때는 인성 및 취성 등의 기계적인 성질과 물리적인 성질을 향상시키기 위하여 금속재의 강섬유를 첨가하여 주고 있다.Generally, when forming concrete structures or bricks, steel fibers of metal materials are added to improve mechanical and physical properties such as toughness and brittleness.
이러한 강섬유는 통상 강선 절단법과 용융공법 및 박판 절단법 등에 의해 성형된다.Such steel fibers are usually molded by a steel wire cutting method, a melting method, a thin plate cutting method, or the like.
이중, 강선 절단법은 금속재의 강선을 일정한 길이로 절단하여 성형하는 것으로, 절단된 것 자체를 그대로 사용하거나 또는 여기에 부착성을 향상시키기 위하여 웨이브를 추가한 것 등이 있다.Of these, the steel wire cutting method is to cut the steel wire of a metal material to a certain length and to form, such as to use the cut itself as it is, or to add a wave to improve the adhesion thereto.
이 강선 절단법에 의해서 얻어진 강섬유는 강도가 우수한 반면, 다른 성형법에 비해 생산원가가 높다는 단점이 있다.The steel fiber obtained by this steel wire cutting method has a high strength, but has a disadvantage of higher production cost than other forming methods.
또한, 용융공법은 금속을 용융시킨 다음, 용융된 금속을 오버 플로우(Over Flow)시켜 얻어내는 것으로, 주형에 따라 강섬유의 크기와 형태가 달라진다.In addition, the melting method is obtained by melting the metal and then overflowing the molten metal, the size and shape of the steel fibers vary depending on the mold.
그리고, 박판 절단법은 받침판의 이송통로 상에 연강판을 올려놓고 이를 서서히 이송시키면서 그 선단을 사이드 컷터로 절단과 동시 성형하여 강섬유를 얻어내는 것이다.In the thin plate cutting method, a mild steel plate is placed on a conveying path of a supporting plate and gradually transferred thereto, and the tip is simultaneously formed by cutting with a side cutter to obtain a steel fiber.
이 박판 절단법은 연강판을 받쳐주는 받침판의 형태에 따라 강섬유의 모양과 형태가 달라지며, 다른 성형법에 비해 원가가 적고 콘크리트 구조물의 보강성을 높일수 있다는 점에서 각광을 받고 있다.This thin plate cutting method is in the spotlight in that the shape and shape of steel fiber varies according to the shape of the supporting plate supporting the mild steel plate, and it is less expensive than other forming methods and can improve the reinforcement of concrete structures.
또한, 상기한 강섬유 외에도 최근에는 합성수지로 된 섬유사가 콘크리트 보강재로 많이 쓰이고 있다.In addition, in addition to the steel fibers described above, fiber yarns made of synthetic resins have recently been used as concrete reinforcement materials.
합성수지재의 섬유사는 강섬유에 비해 제조가 쉽고, 원가가 적으며, 취급이 용이하다는 장점이 있다.Fiber yarn of synthetic resin material has the advantage of easy manufacturing, low cost, and easy handling compared to steel fiber.
종래의 합성수지재로 된 콘크리트 보강용 섬유사는 도 1 및 도 2에서 보는 바와 같이 단사형으로 된 것과 망사형으로 된 것이 있다.Concrete reinforcing fiber yarn made of a conventional synthetic resin material is made of a single yarn type and a mesh type as shown in FIGS. 1 and 2.
이중, 단사형 섬유사(110)는 사출성형에 의해 얻어진 섬유사를 일정한 길이로 절단하여 얻어진 것으로, 외관이 단조롭고 크기가 작기 때문에 콘크리트 혼합물 내에서의 유동성과 분산성이 좋은 반면, 부착성이 떨어지는 단점이 있다.Among them, the single yarn fiber yarn 110 is obtained by cutting the fiber yarn obtained by injection molding to a certain length. Since the appearance is monotonous and small in size, the single yarn fiber yarn 110 has good fluidity and dispersibility in the concrete mixture, but has poor adhesion. There are disadvantages.
그리고, 망사형 섬유사(120)는 상기 단사형 섬유사(110)를 엮어서 망사형으로 제조한 것으로, 외관이 복잡하고 크기가 큰 관계로 부착성이 좋은 반면, 콘크리트 혼합물 내에서의 유동성 및 분산성이 떨어지기 때문에 한 곳으로 몰리는 단점이 있다.In addition, the mesh-like fiber yarn 120 is manufactured by weaving the single yarn-like fiber yarn 110 in a mesh shape, while the appearance is complicated and large in size, the adhesion is good, while fluidity and powder in the concrete mixture are good. There is a drawback to flocking to one place because of acidity.
따라서, 이들 단사형 및 망사형 섬유사(110,120)를 사용하여 콘크리트 구조물을 구축할 경우, 압축 및 충격하중과 인성 등이 물성치가 기준치에 미달하여 콘크리트 구조물의 균열 및 취성방지에 미흡한 문제점이 있었다.Therefore, when constructing concrete structures using these single yarn and mesh fiber yarns 110 and 120, compression and impact loads and toughness, such as physical properties below the standard value had a problem in preventing cracking and brittleness of the concrete structure.
본 고안은 이러한 문제점을 해결하기 위하여 안출한 것으로 그 기술적인 과제는 합성수지로 성형되는 단사형 섬유사에 일정간격으로 압착홈 및 돌출부를 형성하여 유동성 및 부착성이 뛰어나도록 함에 있다.The present invention has been made to solve the above problems, the technical problem is to form a compression groove and a protrusion at a predetermined interval in the single yarn fiber yarn is formed of a synthetic resin to excellent fluidity and adhesion.

상기의 과제를 달성하기 위하여 본 고안은 사출성형에 의해 얻어지는 단사형 섬유사에 일정간격으로 복수개의 압착홈 및 돌출부를 형성한 것이다.In order to achieve the above object, the present invention is to form a plurality of pressing grooves and protrusions at a predetermined interval in the single yarn fiber yarn obtained by injection molding.
이와 같이 구성된 본 고안은 압착홈 및 돌출부로 인해 콘크리트 구조물과의 부착성 및 유동성이 뛰어나게 된다.The present invention configured as described above has excellent adhesion and fluidity with the concrete structure due to the pressing groove and the protrusion.
따라서, 콘크리트 구조물에 폭 넓게 분산되어 구조물의 취성을 개선하고, 인성을 부여해 주므로써 균열방지와 함께 완충효과가 뛰어난 효과를 발휘하게 된다.Therefore, it is widely dispersed in the concrete structure, thereby improving the brittleness of the structure and giving toughness, thereby exhibiting an excellent buffering effect along with crack prevention.
이하에서 본 고안을 첨부된 도면에 의거 보다 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 3은 본 고안에 따른 단사형 섬유사의 사시도이고, 도 4는 정단면도를 나타낸 것이다.Figure 3 is a perspective view of the single yarn fiber yarn according to the present invention, Figure 4 shows a front cross-sectional view.
도시한 바와 같이 본 고안의 콘크리트 보강재는 사출성형에 의해 성형되며 원형의 단면을 갖는 섬유사를 일정길이로 절단하여 얻어지는 단사형 섬유사(10)에 있어서,As shown in the present invention, the concrete reinforcing material is molded by injection molding, and in the single yarn fiber yarn 10 obtained by cutting a fiber yarn having a circular cross section to a predetermined length,
상기 단사형 섬유사(10)에 일정간격으로 복수개의 압착홈(11)을 형성하여 그 양측으로 돌출부(12)를 형성시킨 것이다.A plurality of pressing grooves 11 are formed in the single yarn type fiber yarn 10 at a predetermined interval to form protrusions 12 on both sides thereof.
상기 복수개의 압착홈(11)은 열융착 등에 의해 형성되고, 돌출부(12)는 압착홈의 양측에 일체로 형성된다.The plurality of pressing grooves 11 are formed by thermal fusion, and the like, and the protrusions 12 are integrally formed at both sides of the pressing grooves.
상기 단사형 섬유사(10)의 길이는 6∼60mm 이고, 직경은 0.1∼1.0mm 이며, 압착홈(11)의 간격은 2∼10mm 이다.The single yarn type fiber yarn 10 has a length of 6 to 60 mm, a diameter of 0.1 to 1.0 mm, and a spacing of the crimping grooves 11 to 2 to 10 mm.
상기와 같이 구성된 본 고안의 작용에 대하여 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.
먼저, 본 고안의 단사형 섬유사(10)는 길이가 짧고 비교적 단조로운 형태이기 때문에 콘크리트 혼합물 내에서의 유동성이 좋아 골고루 분산된다.First, since the single yarn type fiber yarn 10 of the present invention has a short length and a relatively monotonous shape, it has good fluidity in the concrete mixture and is uniformly dispersed.
또한, 길이방향에 형성된 복수개의 압착홈(11)과 돌출부(12)는 단사형 섬유사(10)의 표면적을 넓혀주게 되어 콘크리트 구조물과의 부착성을 향상시킨다.In addition, the plurality of pressing grooves 11 and the protrusions 12 formed in the longitudinal direction widen the surface area of the single yarn fiber yarn 10 to improve adhesion to the concrete structure.
따라서, 본 고안의 단사형 섬유사(10)는 콘크리트 구조물에 골고루 분산되어 구조물의 취성을 개선하고, 인성을 부여하므로써 구조물의 균열방지와 완충효과를 뛰어나게 한다.Therefore, the single yarn fiber yarn 10 of the present invention is uniformly dispersed in the concrete structure, thereby improving the brittleness of the structure, and giving toughness, thereby making it excellent in crack prevention and buffering effect of the structure.
이상에서 설명한 바와 같이 본 고안은 합성수지로 형성되는 단사형 섬유사에 일정간격으로 복수개의 압착홈과 돌출부를 형성하여 유동성과 부착성이 뛰어나므로 콘크리트 구조물의 취성 및 인성을 개선하여 구조물의 균열방지와 함께 완충효과가 뛰어난 것이다.As described above, the present invention forms a plurality of crimping grooves and protrusions at a predetermined interval in single yarn fiber yarns formed of synthetic resin, and thus has excellent fluidity and adhesion, thereby improving brittleness and toughness of concrete structures and preventing cracking of structures. Together, the buffer effect is excellent.
