콘크리트 보강섬유{fiber for reinforcing concrete}Fiber for reinforcing concrete

본 고안은 콘크리트의 인장강도, 휨강도, 전단강도 등의 성질을 개선시키기 위해 콘크리트 내에 혼합되는 보강섬유에 관한 것이다. The present invention relates to reinforcing fibers mixed in concrete to improve the properties of tensile strength, flexural strength, shear strength and the like of concrete.

일반적으로 콘크리트는 압축에는 강하나 인장에는 약한 특성이 있고, 갑작스런 파괴를 일으키는 취성을 띄며, 균열에도 취약하다. 최근에는 콘크리트의 인장강도, 내구성 및 안정성을 향상시켜주기 위해 콘크리트에 강섬유, 유리섬유, 합성수지계 섬유와 같은 보강섬유를 혼합하여 사용하고 있다. In general, concrete is strong in compression but weak in tension, brittle, causing sudden fracture, and susceptible to cracking. Recently, in order to improve the tensile strength, durability, and stability of concrete, a mixture of reinforcing fibers such as steel fibers, glass fibers, and synthetic resin fibers is used.

이러한 보강섬유는 콘크리트의 인장강도, 휨강도, 에너지 흡수능력 등을 향상시켜 콘크리트의 취성파괴를 방지하고 연성파괴를 유도한다. 그리고 상기 보강섬유는 균열의 발생 및 진행을 억제하고 균열의 폭을 상당히 줄여주는 장점을 가지고 있어 널리 사용되고 있다. These reinforcing fibers improve the tensile strength, flexural strength and energy absorption capacity of concrete to prevent brittle fracture and induce ductile fracture of concrete. In addition, the reinforcing fiber is widely used because it has the advantage of suppressing the occurrence and progress of the crack and significantly reducing the width of the crack.

이러한 보강섬유는 사용 목적에 따라 재질이나 형상을 달리하여 사용되는데, 특히 합성수지계 섬유는 경화 초기 콘크리트에서 수분 증발로 인해 발생하는 수축균열을 억제하고, 투수성을 감소시켜 콘크리트의 사용성 및 내구성을 향상시킨다. These reinforcing fibers are used in different materials or shapes according to the purpose of use, in particular synthetic resin fibers to suppress the shrinkage cracking caused by the evaporation of water in the concrete during the initial curing, and reduce the permeability to improve the usability and durability of the concrete Let's do it.

하지만, 보강섬유는 기본적으로 콘크리트와의 부착성이 좋아야 본래의 기능 을 발휘할 수가 있다. 보강섬유의 부착성이 떨어지면 보강섬유가 있는 위치에서 콘크리트의 균열이 증가하게 되는 문제가 있다. However, the reinforcing fiber basically has good adhesion with concrete so that it can exhibit its original function. If the adhesion of the reinforcing fiber is poor, there is a problem that the crack of the concrete increases at the position of the reinforcing fiber.

본 고안의 목적은, 콘크리트와의 부착력이 강화된 콘크리트 보강섬유를 제공하는 것이다. It is an object of the present invention to provide a concrete reinforcing fiber reinforced adhesion with concrete.

In addition, the concave portion 27 is formed to be concave relative to the side projection portion 26 as a portion between the two adjacent grooves 22.

또한, 상기 제1성형부(20)는 요홈(22)들이 형성됨에 의해 상기 제2성형부(30) 보다 두께가 얇게 형성되고(T1<T2), 폭이 넓게 형성된다(W1>W2). In addition, since the grooves 22 are formed in the first molding part 20, the first molding part 20 is formed to be thinner than the second molding part 30 (T1 <T2), and is formed to have a wide width (W1> W2).

이하 상기한 바와 같은 구성을 가지는 본 고안에 의한 콘크리트 보강섬유의 작용을 상세하게 설명한다. Hereinafter will be described in detail the action of the concrete reinforcing fiber according to the present invention having the configuration as described above.

본 고안에 의한 보강섬유(10)에 의하면, 외면이 모두 요철형상으로 형성된다. 즉, 보강섬유(10)의 일면은 격자형의 요홈(16)과 돌출부(17)에 의해 요철형상으로 형성된다. 그리고 상기 보강섬유(10)의 타면은 제1성형부(20)에 형성된 요홈(22)과 돌출부(23)들에 의해 요철형상으로 형성된다. 또한, 제1성형부(20)의 두께가 제2성형부(30)의 두께보다 얇게 형성됨에 의해 제1성형부(20)가 요입되는 부분이 되고 제2성형부(30)가 돌출되는 부분이 된다.According to the reinforcing fiber 10 according to the present invention, all of the outer surface is formed into an uneven shape. That is, one surface of the reinforcing fiber 10 is formed in a concave-convex shape by the lattice groove 16 and the protrusion 17. The other surface of the reinforcing fiber 10 is formed in an uneven shape by the recesses 22 and the protrusions 23 formed in the first molding part 20. In addition, since the thickness of the first molding part 20 is formed to be thinner than the thickness of the second molding part 30, the first molding part 20 is recessed, and the second molding part 30 protrudes. Becomes

상기 보강섬유(10)의 일면과 대략 직교하게 형성되는 양측면은 상기 제1성형부(20)가 제2롤러(60)의 돌기부(62)에 의해 눌러짐에 의해 올록볼록하게 형성되어 요철형상(26,27)이 된다. 그리고 상기 제1성형부(20)의 폭이 제2성형부(30)의 폭 보다 크게 형성됨에 의해 상기 제1성형부(20)가 돌출되는 부분이 되고 제2성형부(30)가 요입되는 부분이 된다.Both sides formed to be substantially perpendicular to one surface of the reinforcing fiber 10 is formed convexly convex by pressing the first molding portion 20 by the protrusions 62 of the second roller 60. 26,27). In addition, the width of the first molding part 20 is greater than the width of the second molding part 30, so that the first molding part 20 protrudes and the second molding part 30 is recessed. Becomes a part.

이와 같은 구성의 보강섬유(10)에 의하면, 콘크리트 내에 혼합되었을 때 콘크리트와의 부착력이 증대된다. 이에 따라, 보강섬유가 콘크리트 내에서 기능을 제대로 발휘할 수 있게 된다. 따라서 콘크리트의 균열이 현저히 감소되고 콘크리트의 내구성이 향상된다. According to the reinforcing fiber 10 of such a structure, the adhesion force with concrete increases when it mixes in concrete. Accordingly, the reinforcing fiber can properly function in the concrete. Therefore, the cracking of the concrete is significantly reduced and the durability of the concrete is improved.

It is self-evident.

본 실시예에서는 몸체부(11)의 일면과 타면의 형상이 다른 것으로 설명하였으나, 몸체부의 양면이 모두 위에서 설명한 몸체부(11)의 타면 형상으로 형성될 수도 있다. 즉, 제2롤러(60) 두 개를 서로 마주하여 회전하도록 설치한 상태에서 그 사이에 몸체부(11)를 통과시키는 것에 의해 보강섬유(10)를 성형할 수도 있다. In this embodiment, the shape of one surface and the other surface of the body portion 11 has been described as being different, but both sides of the body portion may be formed in the other surface shape of the body portion 11 described above. That is, the reinforcing fiber 10 may be molded by passing the body part 11 therebetween in a state in which two second rollers 60 are installed to rotate to face each other.

또한, 본 실시예에서는 요철형상을 격자형의 돌기들에 의해 형성되었으나, 반드시 돌기들이 격자형으로 될 필요는 없고, 설계조건에 따라 다양한 형상으로 구성될 수 있다. In addition, in this embodiment, the concave-convex shape is formed by the lattice-shaped projections, but the projections do not necessarily have to be lattice-shaped, and may be configured in various shapes according to design conditions.
