Abstract
Description
본 발명은 콘크리트 보강용 강섬유(steel fiber)에 관한 것으로, 더 상세하게는 인성,인장강도 및 접착력을 증대시킬 수 있도록 한 콘크리트 보강용 강섬유에 관한 것이다.The present invention relates to a steel fiber for concrete reinforcement, and more particularly, to a steel fiber for concrete reinforcement to increase toughness, tensile strength and adhesion.
일반적으로 건축물을 시공함에 있어서는 철근 등을 사용하여 건축물의 골격을 구성하거나 적량의 일정한 칫수로 배근한 후 이에 콘크리트를 타설하여 골격을 구성하는 바, 이와 같은 시공법은 막대한 하중이 예상되는 대형의 건축물에 보편적으로 이용되고 있다.In general, in constructing a building, the structure of the structure is constructed using reinforcing bars, etc., or after reinforcement with a certain dimension, the concrete is poured into the structure. It is commonly used.
그러나, 이는 콘크리트를 타설하기전 철근을 일정한 칫수에 맞추어 절단,결속하는 과정에서 많은 재료의 손실과 인건비의 소요가 불가피하였던 문제점이 있었으며, 특히 터널 등과 같은 구조물의 경우 그 작업의 번거로움은 더욱 가중되는 문제점이 있었다.However, there was a problem in that a lot of material loss and labor cost were inevitable in the process of cutting and binding the reinforcing bars to a certain dimension before placing concrete. There was a problem.
따라서, 근래에는 도 1 내지 도 3에 도시된 바와 같이 작업상의 번거로움을 해소하면서도 철근의 배근효과를 제공하는 강섬유(1)가 제공되었다. 이러한 강섬유(1)는 도 4에서와 같이 주로 토목공사에 사용되는 콘크리트(2)에 첨가되어 콘크리트(2)의 균열을 방지하고 인장강도를 증가시킨다.Therefore, in recent years, the steel fiber (1) to provide the reinforcement effect of the reinforcing bar while eliminating the work hassle as shown in Figures 1-3. This steel fiber (1) is added to the concrete (2) mainly used in civil engineering, as shown in Figure 4 to prevent the crack of the concrete (2) and increase the tensile strength.
그러나, 종래의 강섬유(1)는 도 1 내지 도 3에 도시된 바와 같이 그 표면이 매끄러운 환봉으로 형성되어 그 양단에 절곡부(1a)가 절곡된 단순한 구조로 구성되었기 때문에, 구조상 단면적이 작아 콘크리트와의 접착력이 떨어지고 공사시에 콘크리트 반죽으로부터 쉽게 이탈되는 문제점이 있었으며, 또한 구조적으로 인성,인장강도가 약한 문제점이 지적되었다.However, since the conventional steel fiber 1 is composed of a simple structure in which the surface is formed of a smooth round bar and the bent portion 1a is bent at both ends thereof, as shown in FIGS. There was a problem in that the adhesive strength of the wand fell and was easily detached from the concrete dough at the time of construction, and also a problem that the structural strength and tensile strength were weak.
본 발명의 목적은 상기에서와 같은 종래의 결점을 해소하기 위해 안출한 것으로, 보다 우수한 단면적과 걸림구조를 부여하여 콘크리트와의 접착력을 증대시키고, 또한 구조적으로 인성,인장강도를 증대시킬 수 있도록 한 콘크리트 보강용 강섬유를 제공하는 데 있다.An object of the present invention is to devise to solve the above-mentioned drawbacks, to provide a better cross-sectional area and locking structure to increase the adhesive strength with concrete, and also to increase the toughness and tensile strength structurally. The present invention provides a steel fiber for reinforcing concrete.
상기 목적을 달성하기 위해 본 발명은 강섬유의 표면에 단면적을 증대시키는 요철이 형성되도록 강섬유에 다수개의 압착부를 성형한 것이다.In order to achieve the above object, the present invention is to form a plurality of pressing parts on the steel fiber so that the irregularities to increase the cross-sectional area is formed on the surface of the steel fiber.
이하 첨부된 도면에 따라서 본 발명의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention according to the accompanying drawings in detail.
본 발명은 도 5 내지 도 8에 도시되는 바와 같이, 양단으로 절곡부(11)가 절곡형성된 봉상의 강섬유(10)에 있어서, 상기 강섬유(10)의 외주면에 일정간격을 두고 다수개의 압착부(12)를 성형하여, 이 압착부(12)에 의해 강섬유(10)의 표면으로 단면적을 증대시키는 요철이 형성되도록 구성한 것을 그 기술적 구성상의 특징으로 한다.5 to 8, in the rod-shaped steel fiber 10, the bent portion 11 is bent at both ends, a plurality of crimping portions at regular intervals on the outer circumferential surface of the steel fiber 10 ( 12) is molded and configured to form an unevenness for increasing the cross-sectional area to the surface of the steel fiber 10 by the crimping portion 12.
이와 같이 구성된 본 발명의 강섬유(10)도 콘크리트에 첨가되어 콘크리트의 균열을 방지하고 인장강도를 증가시키는 것은 종래와 같다.The steel fiber 10 of the present invention configured as described above is also added to concrete to prevent cracking of concrete and increase tensile strength as in the prior art.
그러나, 본 발명은 상술한 바와 같이 강섬유(10)의 표면에 압착부(11)가 성형되어 이 압착부(12)에 의해 다수개의 요철이 형성되므로 콘크리트와의 접촉면적이 넓어지고, 또한 압착부(12)로 콘크리트가 채워지므로 이 압착부(12)에 의해 걸림구조가 제공된다.However, in the present invention, as described above, since the crimping portion 11 is formed on the surface of the steel fiber 10 to form a plurality of irregularities by the crimping portion 12, the contact area with the concrete is widened, and the crimping portion is further expanded. Since the concrete is filled with (12), the locking structure is provided by this crimping portion (12).
따라서, 이러한 본 발명은 구조적으로 콘크리트의 인장력 및 강도를 높일 수 있으며, 공사시 강섬유(10)와 콘크리트의 접착면적이 넓어서 견고한 상태로 접착시킬수 있는 장점이 있다.Therefore, the present invention can structurally increase the tensile strength and strength of the concrete, there is an advantage that can be bonded in a solid state because the adhesive area of the steel fiber 10 and concrete wide during construction.
이상에서 살펴본 바와 같이 본 발명의 강섬유는 보다 우수한 단면적과 걸림구조가 부여되기 때문에 콘크리트와의 접착력을 증대시킬 수 있으며, 또한 구조적으로 인성,인장강도를 증대시킬 수 있는 매우 유용한 발명이다.As described above, the steel fiber of the present invention is provided with a better cross-sectional area and a locking structure, thereby increasing adhesion to concrete, and is a very useful invention that can structurally increase toughness and tensile strength.
