본 고안은 콘크리트의 인장강도, 휨강도, 신장능력 및 인성을 개선하기 위해 콘크리트에 균일하게 분산되는 콘크리트구조물 보강용 강섬유에 관한 것으로서, 보다 상세하게는 강성부의 바디부의 표면적을 넓힘으로서, 콘크리트 입자와의 부착면적 및 부착능력이 증대되고, 콘크리트 구조물의 보강특성이 향상되는 콘크리트 구조물 보강용 강섬유를 제공하는 것이다.The present invention relates to a steel fiber for reinforcing concrete structures uniformly dispersed in concrete in order to improve the tensile strength, flexural strength, elongation capacity and toughness of the concrete, more specifically, by increasing the surface area of the body portion of the rigid portion, It is to provide a steel fiber for reinforcing concrete structures, the adhesion area and adhesion capacity is increased, and the reinforcing properties of the concrete structure is improved.
대한민국 특허 제259927호(2000년 3월 29일 등록)에 "콘크리트 구조물 보강용 강섬유"가 소개되어 있다.Republic of Korea Patent No. 259927 (registered on March 29, 2000) is introduced "steel fiber for reinforcing concrete structures".
상기 콘크리트 구조물 보강용 강섬유는 중앙에 일직선으로 수평하게 연장 형성되는 몸톤부와, 상기 몸통부의 양측에 각각 경사꺽임부를 두고 그 셩사꺽임부의 끝단에서 다시 수평하게 절곡되는 수평단부를 가지는 양측의 절곡부들로서 구성된 것에 있어서, 상기 양측의 절곡부들은 상기 몸통부에 대하여 평행한 수평단부대 그몸통부로부터 경사지는 경사꺽임부의 길이 비가 1:1.1 - 1 : 1,2이 됨을 특징으로 한다.The steel fiber for reinforcing the concrete structure is a bent portion on both sides having a body tone portion extending horizontally in a straight line at the center, and a horizontal end portion which is bent horizontally at the end of the twisting portion with inclined bent portions on both sides of the trunk portion, respectively. In the configuration, the bent portions on both sides are characterized in that the ratio of the length of the inclined bending portion inclined from the body portion of the horizontal end portion parallel to the body portion is 1: 1.1-1: 1: 1,2.
상기 콘크리트 구조물 보강용 강섬유는 수평단부대와 경사꺽임부의 길이 비가 1:1.1 - 1 : 1,2를 가짐으로서, 강서유 자체의 보강특성을 대략 10%정도 향상시키고 있지만, 몸통부를 개선하여 보강특성을 향상시키는 것에 대한 언급이 없다.The steel fiber for reinforcing the concrete structure has a ratio of the length of the horizontal end portion and the inclined bending portion of 1: 1.1-1: 1,2, thereby improving the reinforcement characteristics of Gangseo Oil itself by about 10%, but improving the body portion to improve the reinforcement characteristics. There is no mention of improving it.
따라서, 본 고안의 목적은 강성부의 바디부를 구불구불하게 요철시켜 표면적을 넓힘으로서, 콘크리트 입자와의 부착면적 및 부착능력이 증대되고, 콘크리트 구조물의 보강특성이 향상되는 콘크리트 구조물 보강용 강섬유를 제공하는 것이다.Therefore, an object of the present invention is to provide a steel fiber for reinforcing concrete structures by increasing the surface area and the ability to adhere to the concrete particles, by increasing the surface area by winding the body portion of the rigid portion by winding. will be.
도 1은 본 고안에 따른 콘크리트 구조물 보강용 강성유를 도시한 개략도1 is a schematic view showing a rigid oil for reinforcing concrete structures according to the present invention
상기와 같은 목적을 달성하기 위한 본 고안의 바람직한 실시예를 도면을 참조하여 상세하게 설명하기로 한다.Preferred embodiments of the present invention for achieving the above object will be described in detail with reference to the drawings.
도 1을 참조하면, 본 고안에 따른 콘크리트 구조물 보강용 강섬유은 바디부(11)와, 상기 바디부(11)의 양단부에서 굴절되어 경사지게 형성되는 경사부(13)와, 상기 경사부(13)에서 굴절되어 바디부(11)와 평행하게 연장되는 수평단부(15)로 구성된다.1, the steel fiber for reinforcing the concrete structure according to the present invention is the body portion 11, the inclined portion 13 is formed to be inclined to be inclined at both ends of the body portion 11, and the inclined portion 13 It is composed of a horizontal end portion 15 which is refracted to extend in parallel with the body portion 11.
상기와 같이 구성된 콘크리트 구조물 보강용 강섬유에 있어서, 상기 바디부(11)는 구불구불하게 파형으로 형성된다.In the steel fiber for reinforcing the concrete structure configured as described above, the body portion 11 is formed in a wavy shape.
도 1에 바디부(11)의 파형은 4개가 도시되어 있으나, 이것은 예를 들어 도시한 것으로써, 파형의 갯수가 도 1에 도시된 것에 한정되지 않고 다양하게 변경될수 있다는 것을 알 수 있을 것이다.Although four waveforms of the body portion 11 are illustrated in FIG. 1, this is illustrated as an example, and it will be appreciated that the number of waveforms is not limited to that illustrated in FIG. 1 and may be variously changed.
상기와 같이 바디부(11)를 구불구불하게 파형으로 형성시켜 바디부의 표면적이 넓어질 경우, 콘크리트 입자와의 부착면적 및 부착능력이 증대되고, 콘크리트 구조물의 콘크리트의 인장강도, 휨강도, 신장능력 및 인성 등을 향상시키는 보강특성이 향상된다.As described above, when the body portion 11 is formed in a wavy shape and the surface area of the body portion is widened, the adhesion area and adhesion ability with the concrete particles are increased, and the tensile strength, bending strength, elongation capacity and the like of the concrete of the concrete structure are increased. The reinforcement characteristic which improves toughness etc. is improved.
위에서 설명한 바와같이, 본 고안에 따른 콘크리트 구조물 보강용 강섬유는 바디부가 구불구불하게 형성되어, 바디부의 표면적이 넓어짐으로서, 콘크리트 입자와의 부착면적 및 부착능력이 증대되고, 콘크리트 구조물의 콘크리트의 인장강도, 휨강도, 신장능력 및 인성 등을 향상시키는 보강특성이 향상되는 효과가 있다.As described above, the steel fiber for reinforcing the concrete structure according to the present invention, the body portion is formed to be serpentine, the surface area of the body portion is widened, the adhesion area and adhesion capacity with the concrete particles increases, the tensile strength of the concrete of the concrete structure , Reinforcing properties to improve the bending strength, elongation capacity and toughness is improved.
