Description
본 고안은 콘크리트 보강용 강섬유(Steel fibre)에 관한 것으로서 시멘트 몰탈에 혼합함으로써 콘크리트의 응결력 및 충격강도를 보강하기 위한 목적으로 사용되는 것이다.The present invention relates to steel fiber for concrete reinforcement, and is used for the purpose of reinforcing the cohesion and impact strength of concrete by mixing with cement mortar.
콘크리트의 강도를 높이기 위해서는 흔히 모래와 자갈 그리고 철근을 혼합하거나 매립하고 있다. 그러나 철근을 사용할 수 없는 공사 예컨데, 터널시공에 있어서의 숏크리팅이나 철근의 보강력에 더하여 전체적으로 균일한 강도를 부여하기 위한 공사에 있어서는 시멘트 몰탈에 강섬유로 불리우는 작은 철편을 혼합하게 된다.To increase the strength of concrete, sand, gravel and rebar are often mixed or buried. However, in the case of construction where reinforcing bars cannot be used, for example, in the construction to give uniform strength as a whole in addition to shotcreting or reinforcing reinforcement in tunnel construction, small pieces of steel called steel fibers are mixed with cement mortar.
강섬유는 원주형을 기준했을 때 길이에 대한 직경의 비율인 형상비가 30 내지 60이 적합한 것으로 알려져 있으며 통상의 길이는 용도에 따라 25m/m, 40m/m, 50m/m가 선택되고 있다.Steel fibers are known to have a suitable shape ratio of 30 to 60, which is a ratio of diameter to length based on a columnar shape, and a typical length of 25 m / m, 40 m / m, 50 m / m is selected depending on the application.
현재까지 알려진 콘크리트 보강용 강섬유는 단순 파상형 단순 요철형, 꺾쇠형, 아령형, 꺾쇠 아령 혼합형 등이 있는바, 이러한 강섬유들은 콘크리트의 응결력을 높여 콘크리트가 외부의 충격이나 기온변화, 풍화작용 등에 의하여 균열되는 것을 최대한 저지해줄 수 있는 구조와 시멘트 몰탈에 혼합하였을때 균일한 밀도로 충분히 서로 엉클어짐이 발생하지 않는 가장 바람직한 구성을 추구하고 있다.The steel fibers for concrete reinforcement known to date include simple wave-shaped simple irregularities, cramps, dumbbells, and mixed dumbbells. These steel fibers increase the cohesion of concrete, which causes the concrete to be exposed to external impacts, temperature changes, and weathering. In order to prevent cracking as much as possible, when mixed with cement mortar, the most desirable configuration does not sufficiently entangle each other with uniform density.
콘크리트 보강용 강섬유는 산화에 강한 저탄소 강선 또는 저탄소 철판으로 프레스 성형되고 있으며 응결력을 높이기 위하여 가급적 몰탈과 접촉되는 표면적을 넓히고 표면이나 좌ㆍ우 단부에 요철구조나 걸림구조를 취하고 있다.Steel fiber for concrete reinforcement is press-molded with low carbon steel wire or low carbon steel plate that is resistant to oxidation, and in order to increase the cohesive force, the surface area in contact with mortar is increased as much as possible, and the concave-convex structure or the hanging structure is taken on the surface or the left and right ends.
콘크리트 보강용 강섬유는 표면적이 넓어야 하고 효과적인 걸림구조가 형성되어 있어야 하며 서로 엉키지 아니하고 충분히 분산될 수 있는 구조로써 제조공정이 단순하여 양산성이 보장되는 것을 최적의 목표로 하고 있다.The steel fiber for concrete reinforcement should have a wide surface area, an effective locking structure should be formed, and a structure that can be sufficiently dispersed without being entangled with each other.

1 : 수평압착면 2 : 수직압착면1: horizontal pressing surface 2: vertical pressing surface
본 고안은 이러한 목표에 접근할 수 있는 최적의 구조를 가지는 콘크리트 보강용 강섬유를 제공하고자 하는 것으로서, 본 고안의 구조를 첨부한 도면과 함께 상세히 설명하기로 한다.The present invention is to provide a steel fiber for concrete reinforcement having an optimal structure that can approach this goal, the structure of the present invention will be described in detail with the accompanying drawings.
본 고안은 0.8m/m 저탄소 강선을 소재로 하여 압착성형되는바, 타원형의 가까운 수평압착면(1)과 수직압착면(2)을 교호로 연속되게 형성한다.The present invention is press-molded using a 0.8m / m low carbon steel wire bar, to form an elliptical close horizontal pressing surface (1) and vertical pressing surface (2) alternately continuous.
수평압착면(1)과 수직압착면(2)의 최대 세로폭은 1.2~1.5m/m, 두께는 0.4m/m가 적당하며 수평압착면(1)과 수직압착면(2)은 유연하게 뒤틀리듯 연속된다. 저탄소 강선의 직경에 대한 압착면(1)(2) 폭의 비율이 2배 이상이 되면 인장강도가 저하될 수 있다.The maximum vertical width of the horizontal pressing surface 1 and the vertical pressing surface 2 is 1.2 to 1.5 m / m, and the thickness is 0.4 m / m, and the horizontal pressing surface 1 and the vertical pressing surface 2 are flexible. It is twisted and continues. When the ratio of the width of the compressed surface (1) (2) to the diameter of the low carbon steel wire is more than twice the tensile strength may be lowered.
수평압착면(1) 또는 수직압착면(2)은 제4도에 예시한 바와같이 교호로 조절할 경우 굴절부분의 내각은 135℃ 내지 150℃가 적당하다.When the horizontal compression surface 1 or the vertical compression surface 2 is alternately adjusted as illustrated in FIG. 4, the inner angle of the deflection portion is suitably 135 ° C to 150 ° C.
본 고안은 수평압착면(1)과 수직압착면(2)을 교호로 형성함으로써 시멘트 몰탈과의 접촉면적을 넓히고 동시에 효과적인 걸림수단을 제공하고 있다.The present invention broadens the contact area with cement mortar by providing the horizontal pressing surface 1 and the vertical pressing surface 2 alternately, and at the same time provides an effective locking means.
또한 수직과 수평이 교호로 이루어진 압착면(1)(2)들은 제3도의 단면구조에 점선으로 나타낸 공간용적을 차지하므로 강섬유간의 거리가 최대한 넓어져 시멘트 몰탈에 혼합하였을 때 분산효과가 뛰어나다.In addition, the compression surface (1) (2) consisting of alternating vertical and horizontal occupy the space volume indicated by the dotted line in the cross-sectional structure of FIG. 3, so that the distance between the steel fibers is as wide as possible, which is excellent in dispersing when mixed with cement mortar.
본 고안의 강섬유는 시멘트 몰탈 일정량에 일정한 강도를 유지하는데 최소량이 소요되며 일정량의 구조의 강섬유를 혼합하였을 때보다 12 내지 18%만큼 강도가 증가한다.Steel fiber of the present invention takes a minimum amount to maintain a certain strength to a certain amount of cement mortar and increases the strength by 12 to 18% than when a certain amount of steel fibers are mixed.
본 고안의 강섬유는 그 기본 구조만으로도 우수한 보강효과가 있으나 제4도와 같이 교호로 굴절하였을 때에는 분산효과가 더욱 우수하여 강섬유의 혼합량을 줄여야할 경우에도 균일한 콘크리트의 강도를 유지할 수 있다.The steel fiber of the present invention has an excellent reinforcing effect only by its basic structure, but when it is alternately refracted as shown in FIG. 4, the dispersion effect is more excellent, so that even when the mixing amount of the steel fiber is reduced, the uniform concrete strength can be maintained.
