Description
본 발명은 하부 플렌지의 두께가 상부 플렌지의 두께보다 두꺼운 H 형강 및 그 제조 방법에 관한 것으로서, 더욱 구체적으로는 합성보에 사용되는 H 형강의 하부 플렌지를 상부 플렌지보다 두껍게 함으로써 단면 성능을 극대화한 H 형강 및 그 제조 방법에 관한 것이다. The present invention relates to an H-beam having a lower thickness of the upper flange than the thickness of the upper flange and a method of manufacturing the same. And a method for producing the same.
일반적으로, H 형강은 건축물, 토목 구조물 등에 널리 사용되는 단면이 H형인 형강을 의미한다. In general, the H-beam refers to the H-shaped section is widely used in buildings, civil engineering structures and the like.
상기 H 형강은, 도 1에 나타난 바와 같이, 콘크리트 슬래브(12)의 하부에 설치되어 콘크리트 슬래브(12)를 지지하는 데에도 사용된다. 이러한 합성보(10) 구조에서는 중립축(A-A')의 상부가 압축 응력을 받고, 중립축(A-A')의 하부가 인장 응력을 받게 된다. 즉, 콘크리트 슬래브(12) 및 상부 플렌지(14)가 압축 응력을 받게 되고, 하부 플렌지(16)가 인장 응력을 받게 된다. 따라서, 상기 합성보(10)는 하부 플렌지(16)가 단독으로 인장 응력에 저항하기 때문에 단면 2차 모멘트와 인장측 단면 계수가 작다는 문제점을 가지고 있다. 한편, 미설명 참조부호 13은 H 형강을 나타내고, 18은 H 형강(13)과 콘크리트 슬래브(12)를 결합시키는 전단 연결재이다.As shown in FIG. 1, the H-beams are also used in the lower part of the concrete slab 12 to support the concrete slab 12. In the composite beam 10 structure, the upper portion of the neutral axis A-A 'receives compressive stress, and the lower portion of the neutral axis A-A' receives tensile stress. That is, the concrete slab 12 and the upper flange 14 are subjected to compressive stress, and the lower flange 16 is subjected to tensile stress. Therefore, the composite beam 10 has a problem that the cross section secondary moment and the tensile side cross section coefficient are small because the lower flange 16 alone resists tensile stress. On the other hand, reference numeral 13 denotes an H-shaped steel, 18 is a shear connector for coupling the H-shaped steel 13 and the concrete slab 12.
이러한 문제점을 해결하기 위해서 하부 플렌지(16)에 고강도 부재(미도시)를 결합함으로써 단면 2차 모멘트와 인장측 단면 계수 등을 크게 하는 방법이 제안되었다. 그러나, 상기 방법은 고강도 부재의 제작과 결합에 많은 비용이 소요되어 생산비가 증가된다는 문제점이 있다.In order to solve this problem, a method of increasing the cross-sectional secondary moment, the tensile side cross-sectional coefficient, and the like has been proposed by coupling a high strength member (not shown) to the lower flange 16. However, the method has a problem in that the production cost is increased due to the high cost of manufacturing and combining the high strength member.
본 발명은 상기 문제점들을 해결하기 위해 안출된 것으로서, 합성보의 단면 성능을 극대화할 수 있고 저렴한 비용으로 생산할 수 있는, 하부 플렌지의 두께가 상부 플렌지의 두께보다 두꺼운 H 형강 및 그 제조 방법을 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, to provide a H-shaped steel thicker than the thickness of the upper flange, which can maximize the cross-sectional performance of the composite beam and can be produced at a low cost and its manufacturing method There is a purpose.
상기 목적을 달성하기 위해 본 발명의 바람직한 실시예에 따른 H 형강은 하부 플렌지의 두께가 상부 플렌지의 두께보다 두껍다.In order to achieve the above object, H-shaped steel according to a preferred embodiment of the present invention has a thickness of the lower flange is thicker than the thickness of the upper flange.
바람직하게, 상기 H 형강은 상기 하부 플렌지의 폭이 상기 상부 플렌지의 폭보다 넓다.Preferably, the H-beam has a width of the lower flange is wider than the width of the upper flange.
본 발명의 다른 측면인 H 형강의 제조 방법에 따르면, 상부 플렌지의 상면과 하부 플렌지의 하면을 각각 가압하는 한 쌍의 수평 롤과, 상부 플렌지의 하면과 하부 플렌지의 상면 및 웹을 각각 가압하는 한 쌍의 수직 롤을 구비하는 압연기를 이용하여 H 형강을 제조하는 방법에 있어서, 상기 한 쌍의 수직 롤을 상측으로 소정 거리 이동시키는 단계를 포함한다.According to another aspect of the present invention, there is provided a method of manufacturing an H-beam, a pair of horizontal rolls for pressing the upper surface of the upper flange and the lower surface of the lower flange, and the upper surface of the upper flange and the upper surface of the lower flange and the web, respectively. A method of manufacturing an H-shaped steel using a rolling mill having a pair of vertical rolls, the method comprising moving the pair of vertical rolls a predetermined distance upwards.
이하, 본 발명의 바람직한 실시예에 따른 하부 플렌지의 두께가 상부 플렌지의 두께보다 두꺼운 H 형강 및 그 제조 방법을 첨부된 도면을 참조하여 상세히 설명한다. 이에 앞서, 본 명세서 및 청구범위에 사용된 용어나 단어는 통상적이거나 사전적인 의미로 한정해서 해석되어서는 아니되며, 발명자는 그 자신의 발명을 가장 최선의 방법으로 설명하기 위해 용어의 개념을 적절하게 정의할 수 있다는 원칙에 입각하여 본 발명의 기술적 사상에 부합하는 의미와 개념으로 해석되어야만 한다. 따라서, 본 명세서에 기재된 실시예와 도면에 도시된 구성은 본 발명의 가장 바람직한 일 실시예에 불과할 뿐이고 본 발명의 기술적 사상을 모두 대변하는 것은 아니므로, 본 출원시점에 있어서 이들을 대체할 수 있는 다양한 균등물과 변형예들이 있을 수 있음을 이해하여야 한다. Hereinafter, an H-shaped steel having a thickness of a lower flange according to a preferred embodiment of the present invention is thicker than a thickness of an upper flange and a manufacturing method thereof will be described in detail with reference to the accompanying drawings. Prior to this, terms or words used in the specification and claims should not be construed as having a conventional or dictionary meaning, and the inventors should properly explain the concept of terms in order to best explain their own invention. Based on the principle that can be defined, it should be interpreted as meaning and concept corresponding to the technical idea of the present invention. Therefore, the embodiments described in the specification and the drawings shown in the drawings are only the most preferred embodiment of the present invention and do not represent all of the technical idea of the present invention, various modifications that can be replaced at the time of the present application It should be understood that there may be equivalents and variations.
도 2는 본 발명의 바람직한 실시예에 따른 하부 플렌지의 두께가 상부 플렌지의 두께보다 두꺼운 H 형강을 나타낸 단면도이다. 2 is a cross-sectional view showing an H-shaped steel whose thickness of the lower flange is thicker than the thickness of the upper flange according to a preferred embodiment of the present invention.
도 2를 참조하면, 상기 H 형강(100)은 상부 플렌지(22)와, 상부 플렌지(22)의 두께보다 두꺼운 두께를 가지는 하부 플렌지(24) 및, 상부 플렌지(22)와 하부 플렌지(24)를 연결하는 웹(26)을 구비한다. Referring to FIG. 2, the H-beam 100 has an upper flange 22, a lower flange 24 having a thickness thicker than that of the upper flange 22, and an upper flange 22 and a lower flange 24. It has a web 26 for connecting.
상기 상부 플렌지(22)는 콘크리트 슬래브(도 1의 12)와 함께 합성보(도 1의 10)에 작용하는 압축 응력에 저항한다. 따라서, 상부 플렌지(22)는 하부 플렌지(24)에 비하여 그 단면적을 작게 할 수 있다. 즉, 상부 플렌지(22)의 두께를 하부 플렌지(24)의 두께에 비하여 작게 할 수 있다.The upper flange 22 resists compressive stress acting on the composite beam (10 in FIG. 1) with the concrete slab (12 in FIG. 1). Therefore, the upper flange 22 can make the cross-sectional area smaller than the lower flange 24. That is, the thickness of the upper flange 22 can be made smaller than the thickness of the lower flange 24.
바람직하게, 상기 상부 플렌지(22)는 국부 좌굴을 방지할 수 있는 소정의 폭-두께비(b1/T1)를 가진다. 즉, 콘크리트 슬래브(12)의 자중 및 콘크리트 슬래브(12)에 작용하는 하중에 저항하고, 시공시에 콘크리트 슬래브(12)가 경화되기 전까지 압축력에 저항하기 위해서 상부 플렌지(22)가 소정의 폭-두께비(b1/T1)를 가진다. 상기 폭-두께비(b1/T1)는 강구조 계산 규준에 규정되어 있다.Preferably, the upper flange 22 has a predetermined width-thickness ratio b1 / T1 that can prevent local buckling. That is, the upper flange 22 has a predetermined width − to resist the self-weight of the concrete slab 12 and the load acting on the concrete slab 12, and to resist the compressive force until the concrete slab 12 is cured during construction. It has a thickness ratio b1 / T1. The width-thickness ratio b1 / T1 is defined in the steel structure calculation standard.
상기 하부 플렌지(24)는 단독으로 합성보(10)에 작용하는 인장 응력을 받으므로 그 단면적을 크게 하여야 한다. 즉, 하부 플렌지(24)의 두께를 상부 플렌지(22)의 두께보다 두껍게 한다.Since the lower flange 24 is subjected to tensile stress acting on the composite beam 10 by itself, its cross-sectional area should be increased. That is, the thickness of the lower flange 24 is made thicker than the thickness of the upper flange 22.
이와 같이, 상기 H 형강(100)은 상부 플렌지(22)보다 하부 플렌지(24)의 두께가 두껍기 때문에 중립축이 아래로 이동하여 단면 2차 모멘트와 인장측 단면계수가 증가하게 된다.As described above, the H-shaped steel 100 has a thicker thickness of the lower flange 24 than the upper flange 22, so that the neutral axis moves downward to increase the cross-sectional secondary moment and the tension-side cross-sectional coefficient.
또한, 상기 H 형강(100)은 하부 플렌지(24)와 상부 플렌지(22)의 폭이 동일하므로 하부 플렌지(24)와 상부 플렌지(22)의 폭이 서로 다른 H 형강에 비하여 같은 공간에 더 많은 양을 적재할 수 있다.In addition, since the width of the lower flange 24 and the upper flange 22 is the same as the H-shaped steel 100, the width of the lower flange 24 and the upper flange 22 is more in the same space than the different H-shaped steel Can load quantity.
도 3은 롤(roll) 방식을 이용하여 H 형강(100)을 제조하는 과정을 나타낸 구성도이다. 상기 롤 방식은 반제품 형태로 제조된 주조물을 롤 유니트(30)를 이용하는 압연 공정을 거쳐 H 형강으로 제조한다. 이러한 롤 방식의 제조 공정은 H 형강의 제조를 위하여 통상적으로 널리 사용되는 방식이다. 3 is a configuration diagram showing a process of manufacturing the H-shaped steel 100 using a roll (roll) method. In the roll method, the casting manufactured in the form of a semi-finished product is made of H-shaped steel through a rolling process using the roll unit 30. The manufacturing method of such a roll method is a method generally widely used for the production of H-shaped steel.
상기 롤 유니트(30)는 상부 플렌지(22)의 상면과 하부 플렌지(24)의 하면을 가압하는 수평 롤(32) 및, 상부 플렌지(22)의 하면과 하부 플렌지(24)의 상면 및 웹(26)을 가압하는 수직 롤(34)을 구비한다. 수평 롤(32)과 수직 롤(34) 중 적어도 어느 하나는 구동 모터(미도시)에 의하여 회전되며 주조물 즉, H 형강(100)을 이동시킴과 동시에 가압한다.The roll unit 30 includes a horizontal roll 32 for pressing the upper surface of the upper flange 22 and the lower surface of the lower flange 24, the upper surface of the upper flange 22 and the upper surface of the lower flange 24 and the web ( And a vertical roll 34 for pressing 26. At least one of the horizontal roll 32 and the vertical roll 34 is rotated by a drive motor (not shown) and presses simultaneously with moving the casting, that is, the H-beam 100.
이 때, 수직 롤(34)을 상측으로 소정 거리 이동시키면 하부 플렌지(24)를 상부 플렌지(22)보다 두껍게 할 수 있다. 이와 같이, 상기 H 형강(100)은 기존의 H 형강 제조설비를 그대로 이용하여 제조될 수 있기 때문에 추가적인 설비 투자가 필요하지 않다는 장점이 있다. 한편, 도 3에서 점선으로 나타난 부분은 상측으로 이동시키기 전의 수직 롤(34)을 나타낸다. At this time, when the vertical roll 34 is moved a predetermined distance upward, the lower flange 24 may be thicker than the upper flange 22. As such, since the H-beam steel 100 may be manufactured using the existing H-beam steel manufacturing equipment as it is, there is an advantage that no additional facility investment is required. In addition, the part shown with the dotted line in FIG. 3 shows the vertical roll 34 before moving upwards.
한편, 도 4는 본 발명의 바람직한 다른 실시예에 따른 H 형강을 나타내는 단면도이다. 상기 H 형강(200)은 상부 플렌지(52)의 두께(T3)보다 하부 플렌지(54)의 두께(T4)가 두껍고, 상부 플렌지(52)의 폭(b3)보다 하부 플렌지(54)의 폭(b4)이 넓다. 즉, 단면 2차 모멘트와 단면계수를 더욱 크게 할 수 있다. On the other hand, Figure 4 is a cross-sectional view showing an H-shaped steel according to another preferred embodiment of the present invention. The H-shaped steel 200 has a thickness T4 of the lower flange 54 greater than the thickness T3 of the upper flange 52, and a width of the lower flange 54 greater than the width b3 of the upper flange 52. b4) wide In other words, the cross-sectional secondary moment and the cross-sectional coefficient can be made larger.
상술한 바와 같이, 본 발명에 따른 하부 플렌지의 두께가 상부 플렌지의 두께보다 두꺼운 H 형강 및 그 제조 방법은 다음과 같은 효과를 가진다.As described above, the thickness of the lower flange according to the present invention is thicker than the thickness of the upper flange H-shaped steel and its manufacturing method has the following effects.
첫째, 합성보의 단면 성능을 극대화할 수 있는 H 형강 및 그 생산 방법을 제공한다.First, it provides H-shaped steel and its production method that can maximize the cross-sectional performance of composite beams.
둘째, 기존의 생산 설비를 그대로 이용할 수 있고, 저렴한 비용으로 생산할 수 있는 H 형강 및 그 생산 방법을 제공한다.Second, it provides an H-shaped steel and its production method that can be used as it is, and can be produced at low cost.
셋째, 하부 플렌지와 상부 플렌지의 폭이 동일하기 때문에 하부 플렌지와 상부 플렌지의 폭이 서로 다른 H 형강에 비하여 같은 공간에 더 많은 양을 적재할 수 있는 H 형강 및 그 생산 방법을 제공한다.Third, since the width of the lower flange and the upper flange is the same, the width of the lower flange and the upper flange is different than the H-shaped steel can provide a larger amount of H-shaped steel and the production method thereof can be loaded.
