Description
본 고안은 콘크리트용 홈선이 형성된 강섬유에 관한 것이다.The present invention relates to a steel fiber formed with grooves for concrete.
일반적으로 콘크리트 보강용의 강섬유는 0.3-0.5mm의 굵기의 가는 강선을 굵기의 약 80-85배의 길이로 절단하여, 절단된 양단부에 굵기의 8배정도의 수평부와 굵기의 6배정도의 경사부가 좌우 대칭으로 절곡형성된 것으로 강섬유를 콘크리트 몰타르에 사방으로 분산되게 혼합하여 콘크리트 구조물의 강도를 보다 증대시키기 위하여 사용되고 있다.In general, steel fiber for concrete reinforcement cuts 0.3-0.5mm thick steel wire into length of 80-85 times the thickness, and the horizontal portion about 8 times the thickness and the inclined portion about 6 times the thickness are cut at both ends. It is formed to be symmetrically bent and is used to increase the strength of the concrete structure by mixing the steel fibers dispersed in the concrete mortar in all directions.
종래의 강섬유는 표면이 미끄러운 강선으로 되어 있기 때문에 강섬유가 혼합된 콘크리트를 절결하였을 경우 콘크리트와 강섬유의 주면과의 결합성이 강하지 못하고 마찰저항이 높지 못하여 그만큼 콘크리트의 강도를 보강하는 힘이 높지 못한 미비점이 있었다. Conventional steel fiber is a slippery steel wire, so when cutting concrete mixed with steel fiber, the bond between the main surface of concrete and steel fiber is not strong and the frictional resistance is not so high that the strength to reinforce the strength of concrete is not high. There was this.
본 고안은 종래의 이러한 문제점을 시정하고 강섬유와 콘크리트와의 결합강도를 보다 강화시키기 위하여, 소정의 길이로 절단된 가느다란 강섬유의 양단부에 수평부와 절곡부가 좌우 대칭으로 절곡 형성된 것에 있어서, 강섬유의 주면에 다수의 작은 홈선을 일정한 간격의 가로배열이나 사선배열로 압형형성하여 구성된 것이다.The present invention corrects these problems in the prior art, and in order to reinforce the bonding strength between the steel fibers and concrete, the horizontal portions and the bent portions are bilaterally symmetrically formed at both ends of the thin steel fibers cut to a predetermined length. It consists of forming a small number of small groove lines on the main surface by horizontally or diagonally arranged at regular intervals.
본 고안의 강섬유는 주면에 다수의 홈선이 일정한 간격의 가로배열이나 사선배열로 형성되어 있기 때문에 강섬유의 표면적이 보다 증대되고 또한 강섬유의 주면에 형성된 다수의 홈선에 의하여 마찰저항이 크게 된다. Since the steel fiber of the present invention has a plurality of groove lines formed on the main surface in a horizontal or diagonal arrangement at regular intervals, the surface area of the steel fiber is further increased, and the frictional resistance is increased by the plurality of groove lines formed on the main surface of the steel fiber.
따라서 본 고안의 강섬유를 콘크리트 몰타르에 분산되게 혼합하여 콘크리트 구조물을 타설하여 경화하면, 강섬유의 주면에 형성된 홈선에 의하여 콘크리트와의 결합성이 강화되고 콘크리트에 분산된 강섬유의 인장강도에 의하여 콘크리트의 조성강도가 보강된다. 이러한 강섬유의 인장강도의 증대와 마찰저항의 증대의 결합에 의하여 종래의 평활한 강섬유에 비하여 보다 안전하게 콘크리트 강도를 향상시킬 수 있게 안출한 것이다.Therefore, when the steel fiber of the present invention is mixed to be dispersed in concrete mortar and poured to harden the concrete structure, the bond with concrete is strengthened by the groove line formed on the main surface of the steel fiber, and the composition of the concrete by the tensile strength of the steel fiber dispersed in the concrete Strength is reinforced. The combination of the increase in tensile strength and the increase in frictional resistance of the steel fiber is designed to improve the concrete strength more safely than the conventional smooth steel fiber.
도1에 표시된 바와 같이, 소정의 길이로 절단된 약 0.5mm 굵기의 강섬유(1)의 양단부측에 수평부(1a)와 경사부(1b)가 대칭으로 절곡형성 된 것에 있어서, 강섬유(1)의 주면에 도2및 도3에 표시된 바와 같이 다수의 홈선(2)을 일정한 간격의 가로배열(a)이나 사선배열(b)로 압형형성하여 구성된 것이다As shown in Fig. 1, the steel fibers 1 in which the horizontal portions 1a and the inclined portions 1b are symmetrically formed on both ends of the steel fiber 1 having a thickness of about 0.5 mm cut to a predetermined length. As shown in Figs. 2 and 3 on the main surface of the plurality of grooves (2) is formed by pressing the horizontal array (a) or diagonal array (b) at regular intervals
본 고안의 실시에 있어서는 도4에 표시된 바와 같이 강섬유(1)의 대향된 두 주면에 홈선(2)을 형성할 수 있고 도5에 표시된 바와 같이, 강섬유의 대향된 사방의 주면에 홈선(2)을 형성할 수 있다.In the practice of the present invention, as shown in Fig. 4, groove lines 2 can be formed on two opposite main surfaces of the steel fiber 1, and as shown in Fig. 5, the groove lines 2 on opposite main surfaces of the steel fiber are opposite. Can be formed.
이와 같이 된, 본 고안은 강섬유(1)의 주면에 다수의 홈선(2)이 일정한 간격의 가로배열(a)이나 사선배열(b)로 요입되게 형성되어 있기 때문에 강섬유(1)의 표면적이 종래의 것에 비하여 증대되고 또 강섬유의 주면이 형성된 홈선(2)에 의하여 강섬유 주면의 마찰저항이 보다 크게 된다. In this way, the present invention has a large surface area of the steel fiber (1) is formed in the main surface of the steel fiber (1) is formed so that a plurality of groove lines (2) are concaved in a horizontal arrangement (a) or diagonal arrangement (b) of a constant interval The frictional resistance of the steel fiber main surface is increased by the groove line 2 which is increased compared to that and the main surface of the steel fiber is formed.
따라서 본 고안의 강섬유(1)를 콘크리트 몰타르에 분산되게 혼합하여 구조물을 타설하고 경화시키면, 강섬유(1)의 홈선(2)에 콘크리트가 밀착되면서 전체적으로 결합성이 강화된다. 이러한 강섬유의 인장강도와 마찰저항의 증대에 의하여 콘크리트의 조성강도가 보다 증대된다. Therefore, when the steel fiber (1) of the present invention is mixed to disperse the concrete mortar, and the structure is poured and hardened, as the concrete is in close contact with the groove line (2) of the steel fiber (1), the overall bond is reinforced. By increasing the tensile strength and frictional resistance of such steel fibers, the composition strength of concrete is further increased.
또 강섬유의 표면의 마찰저항이 보다 크기 콘크리트와의 결합강도가 강하여 그만큼 콘크리트의 내압강도를 증대시키어 외부 진동이나 충격등으로 인한 콘크리트의 절결이나 균열등을 방지할 수 있다.In addition, the frictional resistance of the surface of the steel fiber is larger, the bonding strength with the concrete is stronger, so that the pressure resistance strength of the concrete can be increased to prevent the cutting or cracking of the concrete due to external vibration or impact.
또 콘크리트의 절결부에서 강섬유가 탈락되는 현상이 없고 이 부분에 시멘트 몰타를를 충전하면 강섬유와의 결합력에 의하여 콘크리트의 절결부분을 보강할 수 있다. In addition, there is no phenomenon that the steel fiber is dropped from the cutout of the concrete, and filling the cement malta in this part can reinforce the cutout of the concrete by the bonding force with the steel fiber.
본 고안은 콘크리트용 강섬유에 있어서, 강섬유의 주면에 다수의 홈선을 일정한 간격의 가로배열이나 사선배열로 압형 형성하였기 때문에 강섬유의 표면적의 증대 및 주면의 마찰저항이 보다 증대 되어서, 콘크리트와 결합강도를 강력하게 증대시키어 그만큼 콘크리트의 압축강도를 높일 수 있고 절결이나 균열등을 방지할 수 있다. In the present invention, in the steel fiber for concrete, many grooves are formed on the main surface of the steel fiber in a horizontal or diagonal arrangement at regular intervals, thereby increasing the surface area of the steel fiber and increasing the frictional resistance of the main surface, thereby increasing the strength of the concrete and the bonding strength. By increasing the strength, the compressive strength of the concrete can be increased, and it is possible to prevent the cutting and the cracking.
또 콘크리트의 절결부분에 노출된 강섬유가 외부로 탈락됨이 없이 콘크리트에 고착되어 있기 때문에 그 부분에 시멘트 몰타르를 주입하면 강섬유와의 견고한 결합에 의하여 보강되는 등 종래의 것에 비하여 강섬유의 효용성이 보다 향상되어 각종 콘크리트 구조물에 유용하게 사용할 수 있는 효과가 있다. In addition, the steel fiber exposed to the cutout of the concrete is fixed to the concrete without falling off to the outside, so when cement mortar is injected into the part, the steel fiber is more effective than the conventional one. There is an effect that can be usefully used in various concrete structures.
